    OBJECTIVES: To compare the efficacy and safety of sedation with midazolam and remimazolam for colorectal endoscopy. METHODS: This single-center, two-arm, post-hoc analysis of the REM-IICTJP01 study investigated the efficacy and safety of remimazolam for gastrointestinal endoscopic sedation. We enrolled 40 and 208 patients who underwent colonoscopy under remimazolam and midazolam sedation, respectively, during the same period. The primary outcome was the time from the end of the colonoscopy until discharge. The secondary outcomes included the time from the end of the colonoscopy until awakening, dosage, and adverse events. Propensity score matching was employed to eliminate the effect of confounding factors. RESULTS: Thirty-seven patients in each group were matched. After propensity matching, the time to awakening after colonoscopy was 28.0 (13.0-37.0) min in the midazolam group and 0 (0-0) min in the remimazolam group; moreover, the time till discharge was 40.0 (35.0-46.5) min in the midazolam group and 0 (0-5.0) min in the remimazolam group, both of which were significantly shorter in the remimazolam group (p < 0.01). The number of additional doses was 0 (0-0) and 2 (1-3) in the midazolam and remimazolam groups, respectively. The total dose was 2.0 (2.0-3.5) and 6.0 (5.0-7.0) mg in the midazolam and remimazolam groups, respectively. CONCLUSIONS: Remimazolam yielded significantly faster times to awakening and discharge safely compared to midazolam.

    INTRODUCTION: We conducted an investigator-initiated clinical trial in which remimazolam was used to achieve sedation in patients undergoing colonoscopy. METHODS: This multicenter, double-blind, placebo-controlled, phase III investigator-initiated trial included patients who underwent colonoscopy under sedation achieved with remimazolam (initial dose: 3 mg; additional doses: 1 mg) or normal saline (placebo). The primary endpoint was the sedation success rate during colonoscopy, defined as successful sedation (modified observer's alertness/sedation [MOAA/S] score ≤4 prior to colonoscopy), the successful completion of the colonoscopy, and no more than five additional doses of remimazolam per 15 min during the procedure. RESULTS: The sedation success rate was 95.0% (38/40 patients) in the remimazolam group and 0.0% (0/11 patients) in the placebo group (p&lt;0.01). The time from the end of the procedure to awakening was 0.0 (interquartile range: 0.0-0.0) min in both groups. The time from the end of the procedure to ambulation was 5.0 min (interquartile range: 0.0-10.0 min) in the remimazolam group and 0.0 min (interquartile range: 0.0-0.0 min) in the placebo group (p=0.02). No serious adverse events occurred. CONCLUSION: The use of remimazolam to achieve sedation in Japanese patients undergoing colonoscopy was more effective than the use of a placebo. CLINICAL TRIAL REGISTRATION: This study was registered in the Japan Registry of Clinical Trials (registration number: jRCT2031200360).

    OBJECTIVES: To assess the effectiveness of remimazolam against normal saline (placebo) as a sedative agent for endoscopy in a multicenter, randomized, double-blind, investigator-initiated phase III controlled trial. METHODS: We included 48 Japanese patients undergoing upper gastrointestinal endoscopy. For the procedure, an initial remimazolam dose of 3 mg and additional doses of 1 mg were administered, as determined in the phase II clinical study. The primary study end-point was the successful sedation rate during gastrointestinal endoscopy, determined as a Modified Observer's Assessment of Alertness/Sedation score ≤4 before the start of endoscopy, the completion of gastrointestinal endoscopy, and two or fewer additional doses per 6 min. RESULTS: The successful endoscopy sedation rates were 91.9% and 9.1% in the remimazolam and placebo groups, respectively (P < 0.01). The time from the end of endoscopy to arousal was 0.0 (0.0-0.0) min for both groups. The number of additional doses required to achieve sedation was lower in the remimazolam group than that in the placebo group (P < 0.01). CONCLUSIONS: Remimazolam demonstrated a significantly higher sedation effect during upper gastrointestinal endoscopy in Japanese patients with safe and fast recovery compared with placebo.

    BACKGROUND: Endoscopic submucosal dissection (ESD) is the standard treatment for early gastric neoplasms (EGN). Controlling intraoperative bleeding is crucial for ensuring safe and reliable procedures. ESD using the spray coagulation mode (SCM-ESD) has been developed to control bleeding more effectively than ESD using the conventional forced coagulation mode (FCM-ESD). This study aims to compare the hemostatic efficacies of SCM-ESD and FCM-ESD. METHODS: This multicenter, prospective, parallel, randomized, open-label superiority trial will be conducted in five Japanese institutions. Patients with a preoperative diagnosis of intramucosal EGC will be randomized to undergo either SCM-ESD or FCM-ESD. The primary outcome measure is the completion of ESD with an electrosurgical knife alone, without the use of hemostatic forceps. Secondary outcomes include the number and duration of hemostasis using hemostatic forceps, procedure time, curability, and safety. A total of 130 patients will be enrolled in this study. DISCUSSION: This trial will provide evidence on the hemostatic efficacy of SCM-ESD compared with FCM-ESD in patients with intramucosal EGN, potentially improving the safety and reliability of ESD procedures. TRIAL REGISTRATION: The trial has been registered at the University Hospital Medical Information Network Clinical Trials Registration (UMIN-CTR) as UMIN000040518. The reception number is R000054009.

    <p>Objectives: Endoscopic submucosal dissection (ESD) is a widely used treatment for early gastrointestinal cancer. However, colon ESD remains challenging. Previous studies on colon ESD using the traction method used a small sample, single-center design, providing insufficient evidence of this procedureʼs efficacy. We thus aimed to investigate the efficacy and safety of the traction method in colon ESD in this multicenter randomized trial.</p><p>Methods: We conducted a prospective, multicenter, randomized, two-arm controlled trial at 10 facilities in Japan. A 1:1 allocation was conducted for the conventional ESD (C-ESD) and traction ESD (T-ESD) groups. The primary end-point was ESD procedure time.</p><p>Results: We included 128 C-ESD and 123 T-ESD cases from April 2020 to August 2021. The median procedure times for C-ESD and T-ESD were 61 (40-100) and 53 (40-76) min (<i>p</i> = 0.18), respectively, and no significant differences were observed between the groups. Subgroup analysis showed that the median procedure times for patients with a lesion diameter of ≥30 mm in the C-ESD and T-ESD groups were 89 (57-80) and 69 (50-104) min (<i>p</i> = 0.05), respectively, and for nonexpert operators were 81 (62-120) and 64 (52-109) min (<i>p</i> = 0.07), respectively.</p><p>Conclusions: The traction method did not contribute to a significantly shortened ESD procedure time. However, this method may be useful when the tumor diameter is large or if the procedure is conducted by nonexpert endoscopists.</p>

    OBJECTIVES: Reflux hypersensitivity (RH) is a form of refractory gastroesophageal reflux disease in which duodenogastroesophageal reflux (DGER) plays a role. This study aimed to determine the usefulness of an endoscopy system equipped with image-enhanced technology for evaluating DGER and RH. METHODS: The image enhancement mode for detecting bilirubin and calculated values were defined as the Bil mode and Bil value, respectively. First, the visibility of the Bil mode was validated for a bilirubin solution and bile concentrations ranging from 0.01% to 100% (0.002-20 mg/dL). Second, visibility scores of the Bil mode, when applied to the porcine esophagus sprayed with a bilirubin solution, were compared to those of the blue laser imaging (BLI) and white light imaging (WLI) modes. Third, a clinical study was conducted to determine the correlations between esophageal Bil values and the number of nonacid reflux events (NNRE) during multichannel intraluminal impedance-pH monitoring as well as the utility of esophageal Bil values for the differential diagnosis of RH. RESULTS: Bilirubin solution and bile concentrations higher than 1% were visualized in red using the Bil mode. The visibility score was significantly higher with the Bil mode than with the BLI and WLI modes for 1% to 6% bilirubin solutions (P < 0.05). The esophageal Bil value and NNRE were significantly positively correlated (P = 0.031). The area under the receiver operating characteristic curve for the differential diagnosis of RH was 0.817. CONCLUSION: The Bil mode can detect bilirubin with high accuracy and could be used to evaluate DGER in clinical practice.

    PURPOSE: Small gastrointestinal stromal tumors (GISTs) can generally have nonspecific CT findings similar to those with benign submucosal tumors of the stomach. The purpose of this study was to explore the potential dual-layer dual-energy CT (dlDECT) parameters to differentiate small-sized (≤ 4 cm) GISTs from leiomyomas of the stomach. MATERIALS AND METHODS: This retrospective study included 26 SMTs ≤ 4 cm in diameter with pathological confirmation of either GIST (n = 17) or leiomyoma (n = 9) from May 2018 to January 2022. All patients received contrast-enhanced CT. The normalized iodine concentration (NIC) and spectral slope (λHU) were compared between GIST and leiomyoma. Receiver-operating characteristic (ROC) curves were plotted and the areas under the curve (AUCs) were calculated to estimate the diagnostic performance of these markers for differentiating GISTs from leiomyomas. RESULTS: NIC was significantly higher in GIST than in leiomyoma in the portal (P = 0.0019) and delayed phases (P = 0.0011). λHU was significantly higher in GIST than in leiomyoma in the portal (P = 0.0006) and delayed phases (P = 0.0009). AUC of the ROC curves using NIC to differentiate between GIST and leiomyoma were 0.875 and 0.895 in the portal and delayed phase; using λHU, they were 0.918 and 0.902 in the portal and delayed phase. CONCLUSION: dlDECT parameters including NIC and λHU show promise as indicators for differentiating small-sized GISTs from leiomyomas.

    BACKGROUND: The clinical course and surveillance strategy for patients who undergo cold snare polypectomy (CSP) for high-grade dysplasia (HGD) or cancer is unclear. We investigated the management of colorectal HGDs and cancers following CSP. METHODS: This Japanese nationwide multicenter exploratory study was retrospectively conducted on patients who had undergone CSP for colorectal HGDs or cancers and follow-up colonoscopy at least once from 2014 to 2020. We investigated the detection rate of CSP scars, local recurrence rate (LRR), risk factors for local recurrence, and follow-up strategy. This study was registered with the University Hospital Medical Information Network (UMIN) Clinical Trials Registry (UMIN000043670). RESULTS: We included 155 patients with 156 lesions. CSP scars were identified in 22 (31.4%), 41 (54.7%), and 10 (90.9%) patients with curative, borderline, and non-curative resection, respectively. Among them, residual tumors were observed in one (4.5%), six (14.6%), and three (30.0%) cases, respectively. The total LRR was 13.7% (95% confidence interval: 6.8-23.8). R1 resection cases (either horizontal or vertical margins positive for tumors) were associated with local recurrence (p = 0.031). Salvage endoscopic and surgical resections were performed on 21 and 10 patients, respectively. Among them, the proportion of endoscopically suspected residual tumors was significantly higher (p < 0.001) in the residual tumor-positive group (100%) than in the residual tumor-negative group (28.6%). CONCLUSIONS: LRR after CSP for HGDs or cancers was 13.7% based on scar-identified cases. Salvage endoscopic or surgical resection should be performed according to the curability of the lesion and endoscopic findings during colonoscopic surveillance.

    BACKGROUND/AIMS: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studies have reported conflicting associations between duodenal tumor development and Helicobacter pylori (H. pylori) infection or endoscopic gastric mucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopic gastric mucosal atrophy. METHODS: This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopic or surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophy and the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies at two of the seven participating institutions. RESULTS: For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected (p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%) control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent risk factor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44-8.40; p<0.001). CONCLUSIONS: Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

    INTRODUCTION: Endoscopic ultrasound guided fine-needle aspiration/biopsy (EUS-FNA/B) is the gold standard for diagnosing subepithelial lesions (SELs); however, its diagnostic ability for SELs <20 mm is low. We developed a new diagnostic method to differentiate between gastrointestinal stromal tumor (GIST) and non-GIST by measuring high-frequency impedance (H-impedance) using an EUS-FNB needle. METHODS: The H-impedance of gastric epithelial neoplasms from 16 cases were measured using a conventional impedance probe to confirm whether H-impedance is clinically useful for assessing cell density (Study 1). The H-impedance values of exposed SELs from 25 cases using the conventional probe (Study 2) and non-exposed SELs from 20 cases using the EUS-FNB needle probe (Study 3) were measured to determine the diagnostic ability of H-impedance for differentiating GISTs from non-GISTs. RESULTS: H-impedance significantly positively correlated with cell density (P=0.030) (Study 1). The H-impedance of GIST (99.5) measured using conventional probe was significantly higher than those of the muscular layer (82.4) and leiomyoma (89.2) (P<0.01) (Study 2). The H-impedance of GIST measured using the EUS-FNB needle was also significantly higher than that of leiomyoma (GIST: 80.2 vs. leiomyoma: 71.8, P=0.015). The diagnostic yield of the impedance method for differentiating GISTs from non-GISTs had 94.4% accuracy, 88.9% sensitivity, 100% specificity, and 0.95 area under the curve. Diagnostic ability was not affected by lesion size (P=0.86) (Study 3). CONCLUSION: Auxiliary differential diagnosis between gastric GISTs and non-GISTs by the H-impedance measurement during EUS-FNB could be a good option especially when the lesion is smaller than 20 mm.

    BACKGROUND & AIMS: Hybrid endoscopic submucosal dissection (H-ESD), which incorporates ESD with endoscopic mucosal resection, has been developed to make ESD technically easier. This study aimed to determine if H-ESD is superior to conventional ESD (C-ESD) for small early gastric neoplasms (EGN). METHODS: We conducted a multi-center, prospective, open-label, randomized controlled trial to compare the treatment outcomes of H-ESD and C-ESD (Hybrid-G Trial). The patients with differentiated-type intramucosal EGN ≤ 20 mm in diameter and without ulceration were randomly assigned (1:1) to groups that underwent H-ESD or C-ESD. A single multi-functional snare, SOUTEN (ST1850-20, Kaneka, Medix, Tokyo, Japan), was used for H-ESD. The primary outcome was procedure time. Secondary outcomes included mucosal incision time, time and speed of submucosal dissection, curability, and endoscopic procedural adverse events. RESULTS: A total of 39 and 40 patients underwent H-ESD and C-ESD, respectively. The procedure time of H-ESD was significantly shorter than that of C-ESD (33.16 min vs. 62.46 min, H-ESD/C-ESD ratio: 0.53, 95% confidence interval 0.41-0.69, P<0.0001). There was no significant difference in mucosal incision time between the two groups; the time and speed of submucosal dissection of H-ESD were significantly shorter than those of C-ESD. No difference was observed between the two groups in other outcomes. CONCLUSIONS: H-ESD has significantly shorter procedure time than C-ESD, with high and comparable curability and safety for both H-ESD and C-ESD. H-ESD can be a good option for the endoscopic treatment of small EGNs.

    Gastrointestinal stromal tumors (GISTs) are common subepithelial lesions (SELs) and require treatment considering their malignant potential. We recently developed an endoscopic ultrasound-based artificial intelligence (EUS-AI) system to differentiate GISTs from non-GISTs in gastric SELs, which were used to train the system. We assessed whether the EUS-AI system designed for diagnosing gastric GISTs could be applied to non-gastric GISTs. Between January 2015 and January 2021, 52 patients with non-gastric SELs (esophagus, n = 15; duodenum, n = 26; colon, n = 11) were enrolled. The ability of EUS-AI to differentiate GISTs from non-GISTs in non-gastric SELs was examined. The accuracy, sensitivity, and specificity of EUS-AI for discriminating GISTs from non-GISTs in non-gastric SELs were 94.4%, 100%, and 86.1%, respectively, with an area under the curve of 0.98 based on the cutoff value set using the Youden index. In the subanalysis, the accuracy, sensitivity, and specificity of EUS-AI were highest in the esophagus (100%, 100%, 100%; duodenum, 96.2%, 100%, 0%; colon, 90.9%, 100%, 0%); the cutoff values were determined using the Youden index or the value determined using stomach cases. The diagnostic accuracy of EUS-AI increased as lesion size increased, regardless of lesion location. EUS-AI based on gastric SELs had good diagnostic ability for non-gastric GISTs.

    BACKGROUND: High-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders (EMDs); however, it requires specialized equipment. The development of more accessible screening examinations is expected. We evaluated the utility of barium esophagography (BE) screening using two novel findings to diagnose EMDs. METHODS: Between January 2013 and October 2020, 244 patients with suspected EMDs who underwent both HRM and BE were analyzed. The EMD diagnosis was based on HRM findings using Chicago Classification version 3.0. BE was performed using sequential esophagography with barium sulfate. Three conventional BE findings (air-fluid level, rosary-bead/corkscrew appearance, and absent/weak peristalsis) and two novel BE findings (wave appearance and supra-junctional ballooning) were used for diagnosis. RESULTS: The sensitivity and specificity of BE screening using the two novel findings and conventional findings to diagnose EMDs were 79.4% and 88%, respectively [area under the receiver-operating characteristic curve (AUC) = 0.837]. Without these novel findings, they were 63.9% and 96%, respectively (AUC = 0.800), respectively. Achalasia was highly correlated with the air-fluid level (88.7%). Absent contractility was highly correlated with absent/weak peristalsis (85.7%). Relatively high correlations were observed between distal esophageal spasm and rosary-bead/corkscrew appearance (60%), and between achalasia and wave appearance (59.7%). The intra-observer reproducibility and inter-observer agreement for individual BE findings were 84.4% and 75%, respectively. Wave appearance was associated with higher integrated relaxation pressure (IRP) and shorter distal latency. Supra-junctional ballooning was associated with higher IRP. CONCLUSIONS: BE screening using two additional novel findings to diagnose EMDs could be useful in general practice.

    OBJECTIVES: Endoscopic submucosal dissection (ESD) is a widely used treatment for early gastrointestinal cancer. However, colon ESD remains challenging. Previous studies on colon ESD using the traction method used a small-sample, single-center design, providing insufficient evidence of this procedure's efficacy. We thus aimed to investigate the efficacy and safety of the traction method in colon ESD in this multicenter randomized trial. METHODS: We conducted a prospective, multicenter, randomized, two-arm controlled trial at 10 facilities in Japan. A 1:1 allocation was conducted for the conventional ESD (C-ESD) and traction ESD (T-ESD) groups. The primary endpoint was ESD procedure time. RESULTS: We included 128 C-ESD and 123 T-ESD cases from April 2020 to August 2021. The median procedure times for C-ESD and T-ESD were 61 (40-100) and 53 (40-76) min (p=0.18), respectively, and no significant differences were observed between the groups. Subgroup analysis showed that the median procedure times for patients with a lesion diameter of ≥30 mm in the C-ESD and T-ESD groups were 89 (57-80) and 69 (50-104) min (p=0.05), respectively, and for non-expert operators were 81 (62-120) and 64 (52-109) min (p=0.07), respectively. CONCLUSIONS: The traction method did not contribute to a significantly shortened ESD procedure time. However, this method may be useful when the tumor diameter is large or if the procedure is conducted by non-expert endoscopists.

    BACKGROUND: Mucosal incision-assisted biopsy (MIAB) is a valuable alternative to endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNAB) for sampling gastric subepithelial lesions (SELs). This study aimed to evaluate the potential risk of dissemination and impact on postoperative prognosis associated with MIAB, which has not yet been investigated. METHODS: Study 1: A prospective observational study was conducted to examine the presence or absence and growth rate of tumor cells in gastric juice before and after the procedure in patients with SELs who underwent MIAB (n = 25) or EUS-FNAB (n = 22) between September 2018 and August 2021. Study 2: A retrospective study was conducted to examine the impact of MIAB on postoperative prognosis in 107 patients with gastrointestinal stromal tumors diagnosed using MIAB (n = 39) or EUS-FNAB (n = 68) who underwent surgery between January 2001 and July 2020. RESULTS: In study 1, although no tumor cells were observed in gastric juice in MIAB before the procedure, they were observed in 64% of patients after obtaining samples (P < 0.001). In contrast, no tumor cells were observed in the gastric juice in EUS-FNAB before and after the procedure. In study 2, there was no significant difference in 5-year disease-free survival between MIAB (100%) and EUS-FNAB (97.1%) (P = 0.27). CONCLUSION: MIAB is safe, with little impact on postoperative prognosis, although the procedure releases some tumor cells after damaging the SEL's pseudocapsule.

    BACKGROUND: Neuroendocrine neoplasms of the ampulla of Vater (ampullary NEN) have features of both gastrointestinal and pancreato-biliary (PB) NEN. However, the limited number of studies examining ampullary NEN makes it difficult to clarify their unique characteristics. This study aimed to elucidate the clinical characteristics of ampullary NEN. METHODS: We enrolled 162 patients with PB-NEN diagnosed at Kyushu University Hospital between 2011 and 2020. Clinical features, pathological diagnoses, treatments, and prognoses were retrospectively analyzed. We also compared ampullary NEN with pancreatic NEN (PanNEN). RESULTS: We analyzed 10 ampullary NEN cases and 149 PanNEN cases. The ampullary NEN cases consisted of four cases of NET G1 (neuroendocrine tumor Grade 1), one NET G2 (Grade 2), and five NECs (neuroendocrine carcinoma). The incidences of NEC and cholangitis were significantly higher in ampullary NEN than in PanNEN. All ampullary NETs had a submucosal tumor-like appearance, as identified by endoscopic ultrasound-guided fine needle aspiration. We treated small NET G1 (<10 mm) with endoscopic papillectomy and large NET G1 with pancreaticoduodenectomy. There were no cases of recurrence after resection. All ampullary NECs presented with the characteristic endoscopic finding of a ''crater sign" similar to deep-mining ulcers seen in gastric malignant lymphoma. Four cases underwent surgical resection, and one case was unresectable. Two patients who underwent multidisciplinary treatment were maintained without recurrence for over 2 years. CONCLUSIONS: Endoscopic findings showed identifiable distinctions between ampullary NETs and NECs.

    Objective: To compare treatment outcomes between injection endoscopic submucosal dissection using ProKnife (P-ESD) and conventional ESD (C-ESD) for gastric lesions. Methods: In this randomized controlled trial, we compared treatment outcomes of P-ESD and C-ESD for simulated gastric lesions ≥3 cm in resected porcine stomachs. Predictive factors associated with ESD difficulties were investigated using logistic regression analysis. Results: Seventy lesions were screened; however, two lesions were excluded. A total of 12 endoscopists performed 68 ESDs: 34 P-ESDs and 34 C-ESDs. The ESD procedure time of P-ESD (36.3 [28.4-46.8] min) was significantly shorter than that of C-ESD (46 [36.4-64.6] min; p = 0.0014). The technical success rates did not differ between the P-ESD and C-ESD groups (en bloc resection rate, 100% in both groups; complete resection rate, 94.1% and 85.3%, respectively; p = 0.23). The number of injections during P-ESD (7.5 [6-10] times) was significantly higher than during C-ESD (4 [3-5] times; p < 0.001), but the total volume of injected solution during P-ESD (20 [16-26.3] ml) was significantly smaller than during C-ESD (27.5 [20-31.5] ml; p = 0.0019). In multivariate analysis, less ESD experience (odds ratio [OR], 3.9) and selection of C-ESD as the ESD method (OR, 3.8) were independent predictive factors associated with ESD difficulties. Conclusions: Compared with C-ESD, P-ESD had a shorter procedure time but also allowed for notable technical success and safety.

    BACKGROUND AND STUDY AIMS: Gastrografin administration (GA) is performed for adhesive small bowel obstruction (ASBO) in cases when decompression therapy using an ileus tube fails to relieve the obstruction. This study evaluated the efficacy of GA and optimized its timing after ileus tube insertion. PATIENTS AND METHODS: In this retrospective study, we evaluated data from patients with ASBO admitted between January 2014 and August 2018 and included patients who underwent ileus tube intubation and GA. The patients were classified as those treated with GA within 48 h after admission (early GA [EGA]) and those treated later with GA (delayed GA [DGA]). Propensity score matching was performed to compensate for differences between the groups. Short-term outcomes were compared between the two groups. RESULTS: We included 67 and 80 patients in the EGA and DGA groups, respectively, and 55 pairs with similar background characteristics were matched. The rates of successful conservative management were 87.3% (48/55) in the EGA group, 96.4% (53/55) in the DGA group, and 91.8% (101/110) in the entire sample. The median period of ileus tube insertion in the DGA group was significantly lower than that in the EGA group, whereas other outcomes did not significantly differ between the groups. Aspiration pneumonia occurred in one patient in the EGA group. CONCLUSIONS: GA with an ileus tube achieved a high rate of successful conservative management. Follow-up using decompression with an ileus tube for at least 48 h after admission is recommended in patients with ASBO.

    BACKGROUND: Endoscopic submucosal dissection (ESD) is widely accepted as a local treatment for gastrointestinal tract tumors. As a simplified endoscopic procedure, hybrid ESD (H-ESD) has been performed for colorectal neoplasms in recent times. However, whether H-ESD is superior to conventional ESD (C-ESD) for patients with early gastric neoplasms (EGN) remains unclear. In this trial, we will compare the treatment outcomes of H-ESD and C-ESD. We hypothesize that the procedure time for H-ESD is shorter than that for C-ESD. METHODS: This is an investigator-initiated, multi-center, prospective, randomized, open-label, parallel-group trial to be conducted beginning in August 2020 at nine institutions in Japan. We will determine if H-ESD is superior to C-ESD in terms of procedure time in patients with EGN diagnosed as macroscopically intramucosal (T1a) differentiated carcinoma ≤ 20 mm in diameter without ulcerative findings according to current Japanese gastric cancer treatment guidelines. A total of 82 patients will be recruited and randomly assigned to either the C-ESD or the H-ESD group. The primary outcome is ESD procedure time. Secondary outcomes include mucosal incision, time and speed of submucosal dissection, en bloc resection, complete resection, curability, adverse events related to the ESD procedure, extent of dissection before snaring, volume of injection solution, number and time of hemostasis, thickness of the submucosal layer in the resected specimen, and handover to another operator. The stated sample size was determined based on the primary outcome. According to a previous report comparing the procedure times of C-ESD and H-ESD, we hypothesized that H-ESD would provide a 0.2 reduction in logarithmically concerted procedure time (-37%). We estimated that a total of 82 participants were needed to reach a power of 80% for a t-test with a significance level of 0.05 and considering a 10% dropout. DISCUSSION: This trial will provide high-quality data on the benefits and risks of H-ESD for EGN patients. The results of this study could lead to improved outcomes in patients with EGN undergoing ESD. The results will be presented at national and international meetings and published in peer-reviewed journals. TRIAL REGISTRATION: UMIN-CTR UMIN000041244 . Registered on July 29, 2020.

    Objectives: The colonic self-expandable metallic stent (C-SEMS) with a 9-French (Fr) delivery system allows for a small-caliber endoscope (SCE) to be used to treat malignant colonic obstruction. Despite the lack of evidence, the SCE has become popular because it is considered easier to insert than the large-caliber endoscope (LCE). We aimed to determine whether the SCE is more suitable than the LCE for C-SEMS placement. Methods: Between July 2018 and November 2019, 50 consecutive patients who were scheduled to undergo C-SEMS for colon obstruction were recruited in this study. Patients were randomized to the SCE or LCE group. The SCE and LCE were used with 9-Fr and 10-Fr delivery systems, respectively. The primary outcome was the total procedure time. Secondary outcomes were the technical success rate, complication rate, clinical success rate, insertion time, guidewire-passage time, stent-deployment time, and colonic obstruction-scoring-system score. Results: Forty-five patients (SCE group, n = 22; LCE group, n = 23) were analyzed. The procedure time in the LCE group (median, 20.5 min) was significantly (p = 0.024) shorter than that in the SCE group (median, 25.1 min). The insertion time in the LCE group (median, 2.0 min) was significantly (p = 0.0049) shorter than that in the SCE group (median, 6.0 min). A sub-analysis of the procedure difficulties showed that the insertion time in the LCE group (median, 5.0 min) was significantly shorter than that in the SCE group (median, 8.5 min). Conclusion: Both LCE and SCE can be used for C-SEMS; however, LCE is more suitable than SCE as it achieved a faster and equally efficacious C-SEMS placement as that of SCE.

    異所性膵は胃角部から前庭部に多く発生する消化管粘膜下腫瘍として見つかることが多い疾患である。多くの異所性膵は良性で経過し診断がつけば基本的には経過観察が可能である。診断は上部消化管内視鏡検査ならびに超音波内視鏡を用いた画像診断や病理学的評価が有用とされている。超音波内視鏡による画像診断は非常に有用であるが、内部の性状だけでなく病変の由来層の確認が極めて重要である。また超音波内視鏡下吸引穿刺細胞診/生検以外の診断法として近年報告が増えている粘膜切開生検が、EUS-FNABで診断困難な症例における新たな診断オプションとして期待される。(著者抄録)

    異所性膵(heterotopic pancreas)は本来の膵臓とは連続性をもたず、血行支配も異なる他臓器に存在する膵組織のことで、大半の異所性膵は無症状で経過することが多い。消化管管腔内に発生する場合、ときに、サイズが増大し閉塞を起こす症例や出血を伴うもの、癌化を伴うものもあり、胃部不快感や痛み症状が出現することもある。その診断は通常光内視鏡での粘膜下腫瘍の確認ならびに超音波内視鏡検査での内部性状、病理学的評価が有用とされているが、超音波内視鏡下吸引穿刺細胞診(EUS-FNAB)でも診断率は十分とは言えず、診断に苦慮する症例も存在する。癌化が疑われる症例、腫瘍径が30mm以上と大きいもの、急速にサイズが増大するものは悪性の可能性があるとされ外科的加療を考慮する必要があるものの、良性例での増大もあり必ずしも悪性とは言えないことに注意が必要である。(著者抄録)

    Language:English   Publishing type:Research paper (scientific journal)  

    BACKGROUND: Intraductal tubulopapillary neoplasm (ITPN) is a rare pancreatic intraductal neoplasm. It is characterized by a tubulopapillary growth pattern, entirely high-grade atypical cells, minimal cytoplasmic mucin, and no obvious luminal mucin secretion. Most of its biological nature remains unclear. CASE PRESENTATION: We herein report a case of intrapancreatic recurrence of ITPN in the remnant pancreas of a patient who underwent pancreatoduodenectomy 16 years previously for a noninvasive intraductal pancreatic head tumor. We reexamined the primary tumor and compared it with the most recently resected specimen. Histologically, the primary tumor showed a tubulopapillary growth of high-grade atypical cells with scanty cytoplasmic mucin, which was similar to the recently resected specimen except for the invasive area. Immunohistochemically, the neoplastic cells in both specimens showed focal staining of MUC1 and positivity for MUC6 but negativity for MUC2, MUC5AC, CDX2, and trypsin. Molecular analysis revealed no KRAS/GNAS/BRAF/PIK3CA mutations in either of the specimens. CONCLUSIONS: These findings of the original tumor and recently resected tumor were compatible with the features of ITPN. Thus, recurrence is possible even for a primary noninvasive ITPN, and long-term surveillance is recommended.

    膵神経内分泌腫瘍(pancreatic neuroendocrine tumor:PanNEN)の術後再発率は比較的高く,再発高リスク群を同定することが予後改善に重要である。最近,われわれはPan-NEN切除例に関する多施設後方視的研究を行い,切除例の疫学データを明らかにした。その中で,NET G1/G2 371例を対象としてAIを用いた再発予測モデルを構築した。PanNET G1/G2の術後再発率は14.0%(52/371)であり,random survival forestモデルは従来のCox比例ハザード回帰モデルよりも優れた再発予測性能を示した。5年無再発生存率はKi-67指数と反比例して直線的に低下することから,実臨床ではKi-67指数の実数値が重要である。また,病変サイズが20mmを超えると無再発生存率が急速に低下し,40mmでプラトーに達した。本稿ではPanNEN診療の現状と課題について概説するとともに,われわれの研究結果の一部を紹介する。(著者抄録)
