The ideal treatment procedure for GI remains controversial.PRESENTATION OF CASE: A 63-year-old female was admitted to our hospital following persistent nausea and vomiting for 7 days. Computed tomography revealed a partially calcified 4-cm circular object in the jejunum, and the proximal intestine was dilated, with concomitant pneumobilia. Based on the preoperative diagnosis of GI, enterotomy with stone extraction by single-incision laparoscopic surgery (SILS) was performed. The patient’s postoperative course was uneventful, and the cholecystoduodenal fistula closed spontaneously 4 months after the surgery.DISCUSSION: Recent studies have reported that enterotomy with stone extraction alone is associated with better outcomes than with more invasive techniques. This case also suggests that enterotomy with s
tone extraction alone and careful postoperative follow-up is feasible for the management of GI. Although the use of laparoscopy in the management of GI has been described previously, laparoscopic surgery has not been widely performed, and SILS is not generally performed. When only this less demanding procedure is required, laparoscopic surgery, including SILS, can be a viable option.CONCLUSION: SILS can be an alternative surgical procedure for the management of GI..

BWS presents with a variety of clinical features, including overgrowth and an increased risk of embryonal tumors. Notably however, reports of patients with BWS and breast tumors are rare, and the association between these conditions is still unclear. Insulin-like growth factor-2 (IGF2) expression is known to be associated with the development of various cancers, including breast cancer, and patients with BWS with specific subtypes of molecular defects are known to show characteristic clinical features and IGF2 overexpression.
Case presentation:A 17-year-old girl who had been diagnosed with BWS based on an umbilical hernia, hyperinsulinemia, and left hemihypertrophy at birth, visited our department with a gradually swelling left breast. Her left breast was markedly larger than her right breast on visual examination. Imaging examinations showed two tumors measuring about 10 cm each in the left breast, and she was diagnosed with juvenile fibroadenoma following core needle biopsy. The two breast tumors were removed surgically and the patient remained alive with no recurrence. The final diagnosis was juvenile fibroadenoma without malignant findings. Immunohistochemical staining using IGF2 antibody revealed overexpression of IGF2 in the cytoplasm of ductal epithelial cells. Because of her clinical features and IGF2 overexpression, molecular defects of 11p15.5 including a possible genetic background of paternal uniparental disomy of chromosome 11 or hypermethylation of imprinting center 1 was suspected.
Conclusions:In this case, overexpression of IGF2 suggested a possible relationship between BWS and breast tumors. Moreover, the characteristic clinical features and IGF2 staining predicted the subtype of 11p15.5 molecular defects in this patient..

This review summarizes the literature describing surgical approaches for MIPD.
Methods: A systematic literature search of PubMed (MEDLINE) was conducted for studies reporting robotic and laparoscopic pancreaticoduodenectomy; the reference lists of review articles were searched. Of 444 articles yielded, 23 manuscripts describing the surgical approach to dissect around the superior mesenteric artery (SMA), including hand-searched articles, were assessed.
Results: Various approaches to dissect around the SMA have been reported. These approaches were categorized according to the direction toward the SMA when initiating dissection around the SMA: anterior approach (two articles), posterior approach (four articles), right approach (16 articles), and left approach (three articles). Thus, many reports used the right approach. Most articles provided a technical description. Some articles showed the advantage of their method in a comparison study. However, these were single-center retrospective studies with a small sample size.
Conclusions: Various approaches for MIPD have been reported; however, few authors have reported the advantage of their methods compared to other methods. Further discussion is needed to clarify the appropriate surgical approach to the SMA during MIPD.
