T. Ueno, M. Wada, K. Hoshino, Toshiharu Matsuura, S. Ida, H. Okuyama, Three-Year Prospective Follow-up of Potential Pediatric Candidate for Intestinal Transplantation, Transplantation Proceedings, 10.1016/j.transproceed.2018.03.067, 50, 9, 2779-2782, 2018.11, Intestinal transplantation (ITx) is a treatment for refractory intestinal failure (IF). However, the indications for and timing of ITx are still controversial because the course of IF is unknown. We performed a prospective multi-institutional cohort study to identify the prognostic factors for referral to an ITx facility. Patients under 18 years of age in Japan who suffered from IF and had received parenteral nutrition for longer than 6 months were enrolled in this study. They were followed up for 3 years. Seventy-two patients were followed. The mean age at the beginning of the study was 7.0 years. Diagnoses were short gut syndrome (n = 25), motility disorder (n = 45), and other (n = 2). The overall 3-year survival rate was 95%. The 3-year survival rate was 86% in patients with intestinal-failure-associated liver disease (IFALD) (n = 6) compared to 97% in those without IFALD (n = 66) (P =.0003). Furthermore, the 3-year survival rates of patients who did and did not meet the criteria for ITx were 82% (n = 11) and 97% (n = 62), respectively (P =.034). Six (44%) of 14 patients whose performance status (PS) was ≥3 at enrollment were dead or still had a PS ≥ 3 at 3 years. This study indicates that IFALD is a poor prognostic factor in pediatric patients with IF. Our indication for ITx, namely the presence of IFALD or loss of more than 2 parenteral nutrition access sites, seems to be applicable.. |

T. Ueno, M. Wada, K. Hoshino, T. Matsuura, H. Okajima, H. Okuyama, Impact of Donor Age on Outcome of Intestinal Transplantation in Japan, Transplantation Proceedings, 10.1016/j.transproceed.2018.04.021, 50, 9, 2775-2778, 2018.11, Background: Donor age for intestinal transplantation (ITx) is somewhat younger than that for other solid organs. Clear criteria for adequate donors have not been established. There is a donor scarcity for ITx in Japan due to the shortage of young donors. Methods: We reviewed outcomes associated with ITx in Japan based on donor age for cadaveric and living donation. Results: Standardized report forms were sent to all known ITx programs, asking for information on ITxs performed between 1996 and 2016. All programs responded. Patient and graft survival estimates were obtained using the Kaplan-Meier method. Five institutions provided data on 27 grafts in 24 patients. There were 14 cadaveric and 13 living donor transplants. Median donor age for ITxs was 40 (range, 17–60) years. Graft survival at 5 years was 66% for patients >40 years old (n = 18) and 47% for those 50 years old (n = 5) and 57% for those 40 years. Donor age for ITx can be extended from >40 to up to 50 years, which may help to mitigate the donor shortage. It will be necessary to clarify the donor criteria for ITx through accumulation of further data on ITx.. |

We aimed to compare the clinical data of BA patients with and without ICH. Methods: Sixty-three BA patients who underwent Kasai portoenterostomy were included in this study. We retrospectively reviewed their clinical records, and compared the ICH and non-ICH groups. Results: ICH occurred in seven patients (11.1%). The patients with ICH were significantly older at the time of Kasai portoenterostomy (median age: 90.0 vs 65.5 days). The hepatobiliary enzyme levels of the patients with ICH were significantly lower in comparison to the patients without ICH (T-Bil 6.7 vs 9.8 mg/dl; AST 95 vs 194 U/L; ALT 44 vs 114 U/L). On the other hand, the coagulation test values of the patients with ICH were significantly higher in comparison to the patients without ICH (PT 50.0 vs 12.4 s; APTT 200.0 vs 36.9 s). Although the survival rates did not differ to a statistically significant extent, persistent neurological sequelae occurred in two patients in the ICH group. Conclusions: The hepatobiliary enzyme levels of the patients with ICH were significantly lower than those without ICH. However, coagulopathy was found to be significantly more progressive in patients with ICH. Levels of Evidence: Level III.. |

a promising new treatment in pediatric surgery, Surgery today, 10.1007/s00595-019-01783-z, 49, 4, 316-322, 2019.04, Stem cells from human exfoliated deciduous teeth (SHEDs), being a type of mesenchymal stem cell, are an ideal cell source for regenerative medicine. They have minimal risk of oncogenesis, high proliferative capacity, high multipotency, and immunosuppressive ability. Stem cell transplantation using SHED has been found to have an anti-fibrotic effect on liver fibrosis in mice. SHED transplantation and the bio 3D printer, which can create scaffold-free 3-D images of the liver and diaphragm, provide a new innovative treatment modality for intractable pediatric surgical diseases such as biliary atresia and diaphragmatic hernia.. |

However, the usefulness and limitations of ICG navigation surgery for hepatoblastoma (HB) have not been fully clarified. We herein report our experiences with surgical navigation using ICG for in HB patients. Methods: In 5 HB patients, 10 ICG navigation surgeries were performed using a 10-mm infrared fluorescence imaging scope after the injection of 0.5 mg/kg ICG intravenously. The surgical and clinical features were collected retrospectively. Results: Navigation surgery using ICG was performed for primary liver tumors in 4 cases, and the timing of ICG injection was 90.5 ± 33.7 h before the operation. All tumors exhibited intense fluorescence from the liver surface. ICG navigation for the primary liver tumor was useful for detecting the residual tumor at the stump and invasion to the diaphragm during surgery. Six lung surgeries using ICG navigation were performed. The timing of ICG injection was 21.8 ± 3.4 h before the operation. The size of the metastatic tumor was 7.4 ± 4.1 mm (1.2–15 mm). Of 11 metastatic tumors detected by computed tomography (CT), 10—including the smallest tumor (1.2 mm)—were able to be detected by ICG from the lung surface. The depth of the 10 ICG-positive tumors from the lung surface was 0.9 ± 1.9 mm (0–6 mm), and the depth of the single ICG-negative tumor was 12 mm. One lesion not detected by CT showed ICG false positivity. Conclusion: Navigation surgery using ICG for patients with HB was useful for identifying tumors and confirming complete resection. However, in ICG navigation surgery, we must be aware of the limitations with regard to the tumor size and the depth from the surface.. |

In 2013, we introduced negative pressure wound therapy as a preventive treatment. We herein report the clinical outcomes of this intervention. Materials and Methods: We conducted a retrospective review of the 26 pediatric liver transplant recipients in our center since 2011. We excluded 1 girl whose wound could not be closed due to bowel edema. The first 13 of the 25 remaining patients were treated with conventional wound management (conventional group). The latter 12 were treated with prophylactic negative pressure wound therapy (prophylactic group). Incidences of surgical complications and patient characteristics were compared between groups. Results: Wound dehiscence occurred in 7 of the 13 patients in the conventional group and 3 of the 12 patients in the prophylactic group. When restricted to dehiscence that required surgical debridement, there were 6 cases in the conventional group and no cases in the prophylactic group. Although background data showed that liver insufficiency in the prophylactic group was more severe, this group had a lower incidence of wound dehiscence (P = .015). Conclusions: Prophylactic negative pressure wound therapy is thought to be effective for preventing wound dehiscence among pediatric liver transplant recipients.. |

Due to the superior survival and higher differentiation efficiency, three-dimensional spheroid culture systems have been an important topic of MSC research. Stem cells from human exfoliated deciduous teeth (SHED) have been considered an ideal source of MSCs for regenerative medicine. Thus, in the present study, we introduce our newly developed method for fabricating SHED-based micro-hepatic tissues, and demonstrate the therapeutic effects of SHED-based micro-hepatic tissues in mouse disease models. Methods: SHED-converted hepatocyte-like cells (SHED-HLCs) were used for fabricating spherical micro-hepatic tissues. The SHED-HLC-based spheroids were then transplanted both into the liver of mice with CCl4-induced chronic liver fibrosis and the kidney of factor VIII (F8)-knock-out mice. At 4 weeks after transplantation, the therapeutic efficacy was investigated. Results: Intrahepatic transplantation of SHED-HLC-spheroids improved the liver dysfunction in association with anti-fibrosis effects in CCl4-treated mice. Transplanted SHED-converted cells were successfully engrafted in the recipient liver. Meanwhile, renal capsular transplantation of the SHED-HLC-spheroids significantly extended the bleeding time in F8-knock-out mice. Conclusions: These findings suggest that SHED-HLC-based micro-hepatic tissues might be a promising source for treating pediatric refractory diseases, including chronic liver fibrosis and hemophilia A.. |

The aim of this study was to evaluate the utility of near-infrared fluorescence cholangiography (NIR-FCG) with ICG in primary surgery for biliary atresia (BA). Methods: We performed NIR-FCG with ICG in 10 BA patients and observed the fluorescence of their hilar micro-bile ducts and hilar exudate in order to assess the appropriate level at which to dissect the hilar fibrous corn. We compared the jaundice outcome of 10 patients using NIR-FCG (Group A) to that of 35 historical patients in whom NIR-FCG had not been used (Group B). Results: The mean age of patients was 74.8 days. The classification of BA was type I in two cases and type-III in eight cases. NIR-FCG visualized the hilar micro-bile ducts, and the incidence of positive fluorescence was 80%. The ratio of postoperative normalization of hyperbilirubinemia in Group A was significantly higher than that in Group B (1.0 vs. 0.65, p |

Tsuyoshi Iwanaka, Takayoshi Yamaza, Soichiro Sonoda, Koichiro Yoshimaru, Toshiharu Matsuura, Haruyoshi Yamaza, Shouichi Ohga, Yoshinao Oda, Tomoaki Taguchi, A model study for the manufacture and validation of clinical-grade deciduous dental pulp stem cells for chronic liver fibrosis treatment, Stem Cell Research and Therapy, 10.1186/s13287-020-01630-w, 11, 1, 2020.03, Background: Human deciduous pulp stem cells (hDPSCs) have remarkable stem cell potency associated with cell proliferation, mesenchymal multipotency, and immunosuppressive function and have shown beneficial effects in a variety of animal disease models. Recent studies demonstrated that hDPSCs exhibited in vivo anti-fibrotic and anti-inflammatory action and in vivo hepatogenic-associated liver regeneration, suggesting that hDPSCs may offer a promising source with great clinical demand for treating liver diseases. However, how to manufacture ex vivo large-scale clinical-grade hDPSCs with the appropriate quality, safety, and preclinical efficacy assurances remains unclear. Methods: We isolated hDPSCs from human deciduous dental pulp tissues formed by the colony-forming unit-fibroblast (CFU-F) method and expanded them under a xenogeneic-free and serum-free (XF/SF) condition; hDPSC products were subsequently stored by two-step banking including a master cell bank (MCB) and a working cell bank (WCB). The final products were directly thawed hDPSCs from the WCB. We tested the safety and quality check, stem cell properties, and preclinical potentials of final hDPSC products and hDPSC products in the MCB and WCB. Results: We optimized manufacturing procedures to isolate and expand hDPSC products under a XF/SF culture condition and established the MCB and the WCB. The final hDPSC products and hDPSC products in the MCB and WCB were validated the safety and quality including population doubling ability, chromosome stability, microorganism safety, and stem cell properties including morphology, cell surface marker expression, and multipotency. We also evaluated the in vivo immunogenicity and tumorigenicity and validated in vivo therapeutic efficacy for liver regeneration in a CCl4-induced chronic liver fibrosis mouse model in the final hDPSC products and hDPSC products in the WCB. Conclusion: The manufacture and quality control results indicated that the present procedure could produce sufficient numbers of clinical-grade hDPSC products from a tiny deciduous dental pulp tissue to enhance clinical application of hDPSC products in chronic liver fibrosis.. |

We conducted a multinational, retrospective study on patients who underwent ITx in Korea, Taiwan, and Japan, to provide an overview and to foresee future developments and collaborations in this region. RECENT FINDINGS: Total 71 ITx were performed in 67 patients. Living donor ITx was most commonly conducted in Japan (n = 13). Despite the low caseload, all three countries demonstrated acceptable patient survival rates of approximately 70% at 5 years. Over 70% of recipients with a functioning graft were free from total parenteral nutrition. SUMMARY: There is an urgent need to establish a nationwide and multinational registry of ITx recipients and patients with intestinal failure in East Asia. An efficient referral system to specialized intestinal rehabilitation and ITx centers and a multidisciplinary team approach is also warranted to provide state-of-the-art treatment for patients desperately waiting for a chance to survive.. |

a retrospective study, Transplant International, 10.1111/tri.13131, 31, 6, 620-628, 2018.06, A graft volume/standard liver volume ratio (GV/SLV) > 35% or graft/recipient weight ratio (GRWR) > 0.8% has been considered as a standard criteria of graft selection. Even if the graft size meets these selection criteria, small-for-size syndrome can still occur depending on the portal venous flow (PVF). The aim of this study was to identify other factors contributing to portal hyperperfusion and the post-transplant course, focusing on the graft volume-to-spleen volume ratio (GV/SV). Thirty-seven BA patients who underwent living donor liver transplantation were reviewed retrospectively. First, we evaluated the preoperative factors contributing to portal hyperperfusion. Second, we evaluated the factors contributing to post-transplant complications, such as thrombocytopenia, hyperbilirubinemia, and coagulopathy. The GV/SLV was >35% in all cases; however, portal hyperperfusion (≥250 ml/min/100 g graft) was found in 12 recipients (35.3%). Furthermore, although the GRWR was >0.8% in over 90% of cases, portal hyperperfusion was found in 10 recipients (32.3%). In contrast, the GV/SV showed a significant correlation with the PVF after reperfusion. If the GV/SV was |

Our aim was to investigate the clinical features and establish the optimal management of CPSVS with or without PAH. Methods: Twenty-four patients with CPSVS treated in Kyushu University Hospital between 1990 and 2015 were enrolled in this study. The patients were divided into a PAH group (n = 9) and a non-PAH group (n = 15). Clinical characteristics and outcomes were evaluated. Results: The first manifestation of CPSVS at diagnosis (28.5 [1-216] months) was hypergalactosemia in 13 (54%) or PAH in six (25%) patients. PAH was the cause of all three deaths. The PAH group had higher levels of serum total bile acid, manganese, and total bilirubin, along with higher pulmonary vascular resistance index (PVRI) than the non-PAH group (7.2 [5.1-38.1] vs 1.2 [0.5-3.3] unit/m2, P |

Toshiharu Matsuura, Yusuke Yanagi, Makoto Hayashida, Yoshiaki Takahashi, Koichiro Yoshimaru, Tomoaki Taguchi, The incidence of chylous ascites after liver transplantation and the proposal of a diagnostic and management protocol, Journal of Pediatric Surgery, 10.1016/j.jpedsurg.2017.06.004, 53, 4, 671-675, 2018.04, Background: No protocol has been established for the diagnosis and management of chylous ascites after liver transplantation (LT). In this study, we retrospectively reviewed our cases of posttransplant chylous ascites (PTCA) and aimed to propose a diagnostic and management protocol. Patients and methods: We retrospectively reviewed the clinical records of 96 LT recipients who underwent LT at our department. The incidence of PTCA and the associated risk factors were analyzed and our protocol for chylous ascites was evaluated. Results: PTCA occurred in 6 (6.3%) patients (mean age: 10.7 ± 11.0 years) at a mean of 10.8 ± 3.6 days after LT. The primary disease in all of PTCA cases was biliary atresia (BA). The periportal lymphadnopathy was an independent risk factor for PTCA. In all cases PTCA successfully resolved according to our protocol. Octreotide was administered in 4 of our 6 PTCA cases. The mean postoperative hospital stay was 40.2 ± 8.4 days, which was similar to that of cases without PTCA. Conclusions: The incidence of PTCA in LT patients, especially in those with BA, is relatively high. Our diagnostic criteria and our management protocol were helpful for patients with refractory ascites after LT. Type of study: Diagnostic test: Level II. Treatment study: Level III.. |

Our aim was to investigate the clinical features and establish the optimal management of CPSVS with or without PAH. Methods: Twenty-four patients with CPSVS treated in Kyushu University Hospital between 1990 and 2015 were enrolled in this study. The patients were divided into a PAH group (n = 9) and a non-PAH group (n = 15). Clinical characteristics and outcomes were evaluated. Results: The first manifestation of CPSVS at diagnosis (28.5 [1-216] months) was hypergalactosemia in 13 (54%) or PAH in six (25%) patients. PAH was the cause of all three deaths. The PAH group had higher levels of serum total bile acid, manganese, and total bilirubin, along with higher pulmonary vascular resistance index (PVRI) than the non-PAH group (7.2 [5.1-38.1] vs 1.2 [0.5-3.3] unit/m2, P |

In vivo and ex vivo methods for growing a liver bud are essential for paving the way for the clinical translation of liver bud transplantation. We herein report a novel transplantation method for liver buds that are grown in vivo involving orthotopic transplantation on the transected parenchyma of the liver, which showed long engraftment and marked growth in comparison to heterotopic transplantation. Furthermore, this study demonstrates a method for rapidly fabricating scalable liver-like tissue by fusing hundreds of liver bud-like spheroids using a 3D bioprinter. Its system to fix the shape of the 3D tissue with the needle-array system enabled the fabrication of elaborate geometry and the immediate execution of culture circulation after 3D printing-thereby avoiding an ischemic environment ex vivo. The ex vivo-fabricated human liver-like tissue exhibited self-tissue organization ex vivo and engraftment on the liver of nude rats. These achievements conclusively show both in vivo and ex vivo methods for growing in vitro-generated liver buds. These methods provide a new approach for in vitro-generated liver organoids transplantation.. |

The aim of this study was to analyze the clinical features and parameters that contribute to a diagnosis of BA. Methods: From January 2000 to December 2013, 37 patients who underwent operative cholangiography were evaluated retrospectively. The patients were divided into two groups: a BA group, and a group with other cholestatic diseases (non-BA group). The demographic data and preoperative liver function test results were analyzed. Results: Of the 37 patients, 29 patients were confirmed to have BA. Age at operation was not significantly different between the two groups (P = 0.77). On preoperative liver function tests, only the level of γ-glutamyl transpeptidase (γ-GTP) was significantly higher in the BA group (P = 0.015). The predominant non-BA disease was inspissated bile syndrome (IBS). In the IBS patients, the jaundice was relieved after lavage of the biliary tree. Conclusion: The preoperative differentiation of cholestasis is difficult based on laboratory data and imaging. Preoperative γ-GTP may be useful for diagnosing BA, but operative cholangiography should be performed when BA is suspected and cannot be ruled out by other methods, given that the most common non-BA disease may be IBS.. |

We aimed to investigate a morphological study of the removed livers and the patient's clinical status. Methods: We examined 8 BA patients who had undergone LT in adulthood at our hospital. The presence of hypertrophic or atrophic areas of the removed liver was recorded macroscopically. We graded the microscopic findings in the porta hepatis area, a hypertrophic area, and an atrophic area, respectively. Moreover, we investigated the relationship between these morphological findings and the pre-transplant clinical status (MELD score). Results: Macroscopically, a hypertrophic area existed in central liver in all cases (8/8 cases), while an atrophic area was existed in peripheral liver (7/8 cases). Microscopically, an atrophic area was the most severely impaired, while the porta hepatis and hypertrophic area were relatively intact. The pathological score in a compensatory hypertrophic area was strongly correlated with the MELD score. Conclusions: This study suggests that the partial shrinking is not uncommon in BA cirrhotic liver. It may be due to the imbalance of bile drainage by the different segment. The patient's pre-transplant status depends on the compensatory hypertrophic liver.. |

Focus on long-term outcomes, Journal of Pediatric Gastroenterology and Nutrition, 10.1097/MPG.0b013e3182421878, 54, 4, 552-557, 2012.04, BACKGROUND AND AIM: The prophylactic oral administration of vitamin K to newborns has markedly reduced the incidence of vitamin K deficiency (VKD); however, intracranial hemorrhage (ICH) is still one of the complications found in biliary atresia (BA) patients and is associated with VKD bleeding. Therefore, we aimed to investigate the incidence and long-term outcome of ICH in patients with BA who previously received prophylactic vitamin K during the neonatal period. METHODS: Eighty-eight consecutive infants with BA were treated and followed up at Kyushu University Hospital from 1979 to 2009. The clinical records and imaging study results were retrospectively reviewed in the infants with BA who presented with ICH. RESULTS: ICH occurred in 7.95% of patients with BA. The onset of ICH occurred at 47 to 76 days after birth, before the patients underwent surgery for BA (9-37 days after the onset of ICH). Coagulopathy was found upon admission in all of the cases with available data and improved after intravenous administration of vitamin K. A craniotomy was required in 2 cases before the surgery for BA. During the 22 to 278 months of follow-up, some neurologic sequelae persisted in 5 of 7 cases. Follow-up head computed tomography scans showed a low-density area in the left hemisphere in 5 cases. CONCLUSIONS: Although vitamin K prophylaxis had been given during the neonatal period, ICH-associated VKD bleeding was still found in 7.95% of patients with BA. Persistent neurologic sequelae were found in 5 of 7 cases, with low-density area in the left hemisphere.. |

Materials and Methods: A total of 57 LDLTs were performed between October 1996 and December 2010. There were 16 cases (28%) with PVT/PVS that underwent modified portal vein anastomosis (m-PVa). The m-PVa techniques were classified into 3 groups: patch graft (Type-1), interposition graft (Type-2), and using huge shunt vessels (Type-3). The reconstruction patterns were evaluated with regard to age, graft vessels, PV flow, and complication rate. Results: The m-PVas were Type-1 in 10 cases, Type-2 in 3 cases, and Type-3 in 3 cases. The vessel graft in Type-1 was the inferior mesenteric vein (IMV) in 8 and the jugular vein in 2 cases, whereas the vessel graft in Type-2 was IMV in 2 and the saphenous vein in 1 case; in Type-3, the vessel grafts were renoportal, gonadal-portal, and coronary-portal anastomoses, respectively. The postoperative PV flow was sufficient in all types and slightly higher in Type-3. The postoperative complications occurred in 20% of the patients who underwent Type-1, in 33% who underwent Type-2, and in 0% who underwent Type-3. Conclusion: The m-PVa was effective to overcome the surgical difficulty during transplantation. Pretransplant planning for the selection of the type of reconstruction is important for recipients with PVT/PVS.. |
