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]
