]]> Introduction
Duodenal perforations are a rare complication during interventional endoscopy. Their mortality is high, and the treatment in most cases is surgical.
We report a case of duodenal perforation (type I, Stapfer) (1) during an interventional endoscopic ultrasound (EUS) procedure resolved using an over-the-scope clip called OTSC®.
Case report
A 74-year-old woman presented obstructive jaundice. Computed tomography revealed a pancreatic head tumor with dilatation of the common bile duct (CBD) and pulmonary metastases. Biliary drainage by ERCP was indicated.
Papilla had tumoral signs of infiltration. Cannulation was not achieved after several attempts with a papillotome. We accessed the distal CBD after performing a pre-cut, but the guidewire could not pass deeply. After replacing the duodenoscope with a linear echoendoscope with the intention of performing biliary drainage guided by EUS, a 10 mm duodenal perforation (type I, Stapfer) was visualized in the posterior wall of the duodenal bulb (Fig. 1A), surely caused by the tip of the echoendoscope. An OTSC atraumatic clip (9.5-11 mm) was deployed with successful closure of the perforation (Fig. 1B). Two endoclips were applied in a margin to ensure complete sealing.
An immediate abdominal CT reported air in retroperitoneum without free fluid (Fig. 2A). The patient was maintained on absolute diet and received antibiotics. Gastrointestinal transit at 5 days showed no extraluminal leakage (Fig. 2 B). Oral feeding was restarted on day 6 and biliary drainage was performed by PTC.
Discussion
]]> The risk of duodenal perforation may be increased in cases of tumor infiltration and passage of an echoendoscope. The use of these OTSC clips is limited in duodenum; however, there are reports in animal models (2) and clinical case series (3-5) supporting its efficacy. We believe that OTSC clips are useful in the closure of duodenal perforations caused by interventional endoscopy.
