Acute duodenal perforation during endoscopic ultrasound (EUS) is a serious complication. The conventional endoscopic treatment for duodenal perforations such as endoscopic clipping is unsatisfactory; recently, the effectiveness of over-the-scope clipping (OTSC) has been reported. A 91-year-old woman was referred to our hospital with the chief complaint of jaundice. Contrast-enhanced computed tomography showed a 2-cm mass in the pancreatic head; we planned EUS-guided fine-needle aspiration. During exploration for a puncture route from the duodenal bulb using a linear echoendoscope under carbon dioxide insufflation, the duodenal lumen was suddenly filled with blood. A perforation

Abstract Background Methods have been developed for preventing delayed bleeding (DB) after gastric endoscopic submucosal dissection (GESD). However, none of the methods can completely prevent DB. We hypothesized that DB could be prevented by a modified search, coagulation, and clipping (MSCC) method for patients at low risk for DB and by combining the use of polyglycolic acid sheets and fibrin glue with the MSCC method (PMSCC method) for patients at high risk for DB (antibleeding [ABI] strategy). This study assessed the technical feasibility of this novel strategy. Method We investigated 123 lesions in 121 consecutive patients who underwent GESD in Kushiro Rosai Hospital between April 2018 and January 2020. The decision for continuation or cessation of antithrombotic agents was based on the Guidelines for Gastroenterological Endoscopy in Patients Undergoing Antithrombotic Treatment. Results Oral antithrombotic agents were administered to 28 patients (22.8%). The en bloc R0 resection rate was 98.4%. The MSCC method and the PMSCC method for preventing DB were performed in 114 and 9 lesions, respectively. The median time of the MSCC method was 16 min, and the median speed (the resection area divided by the time of method used) was 3.6 cm2/10 min. The median time of the PMSCC method was 59 min, and the median speed was 1.3 cm2/10 min. The only delayed procedural adverse event was DB in 1 (0.8%) of the 123 lesions. Conclusions The ABI strategy is feasible for preventing DB both in patients at low risk and in those at high risk for DB after GESD, whereas the PMSCC method may be necessary for reduction of time.

Acute duodenal perforation during endoscopic ultrasound (EUS) is a serious complication. The conventional endoscopic treatment for duodenal perforations such as endoscopic clipping is unsatisfactory; recently, the effectiveness of over-the-scope clipping (OTSC) has been reported. A 91-year-old woman was referred to our hospital with the chief complaint of jaundice. Contrast-enhanced computed tomography showed a 2-cm mass in the pancreatic head; we planned EUS-guided fine-needle aspiration. During exploration for a puncture route from the duodenal bulb using a linear echoendoscope under carbon dioxide insufflation, the duodenal lumen was suddenly filled with blood. A perforation <15 mm was identified in the superior duodenal horn. We attempted an endoscopic closure with multiple endoclips but could not completely close the perforation site. Strips of bioabsorbable polyglycolic acid (PGA) sheets were placed over the gaps between the endoclips with biopsy forceps and fixed in place with fibrin glue, completely covering the perforation site. Two days after the procedure, the perforation site had closed. Nine days later, endoscopic biliary stenting was performed. The patient was diagnosed with pancreatic cancer through bile cytology, and the optimal supportive care for her age was selected. Endoscopic tissue shielding with PGA sheets and fibrin glue is increasingly being reported for use during gastrointestinal endoscopic procedures. In this case, surgery was avoided due to successful endoscopic treatment using endoclips and PGA sheets with fibrin glue without OTSC. This method may be useful for repairing acute duodenal perforations during EUS and should therefore be known to pancreatobiliary endoscopists. [ABSTRACT FROM AUTHOR]

• Rectovaginal fistula is a refractory complication following low anterior resection for rectal cancer. • Rectovaginal fistula is often managed with stoma creation, closure of the fistula and/or re-anastomosis. • Our case was successfully treated with primary closure of the fistula following administration of estriol. Rectovaginal fistula (RVF) is a refractory complication that occurs after anastomotic leakage following low anterior resection for rectal disease. Due to its refractory nature, RVF is often managed with surgical treatment, such as stoma creation for fecal diversion, closure of the fistula and/or re-anastomosis, rather than conservative therapy. A 72-year-old woman who underwent laparoscopic low anterior resection developed RVF on post-operative day (POD) 15. Conservative therapy with the administration of estriol and total parenteral nutrition was started. In addition, a polyglycolic acid (PGA) sheet was inserted into the fistula using colonoscopy, and fibrin glue was applied. However, this treatment with the PGA sheet and fibrin glue seemed to be unsuccessful. Therefore, an operation for simple closure of the RVF was performed on POD47. The PGA sheet was then removed, and primary closure of the RVF from both sides of the rectum and vagina was performed. Following re-operation, solid food with low dietary fiber content was started on original POD55 (POD14 after re-operation), and the dietary fiber content was gradually increased. The patient was discharged from the hospital on original POD 83 (re-operation POD42). The administration of estrogen might result in increased vaginal compliance, decreased vaginal pH, increased vaginal blood flow and improved lubrication. Therefore, vaginal suture was made possible because the vaginal extensibility was restored. Primary closure of the RVF following administration of estriol may be an effective treatment.
