Clinical observation of endoscopic submucosal dissection for uppergastrointestinal ectopic pancreas (36 cases) / 中国内镜杂志

ABSTRACT

Objective To evaluate the feasibility, efficacy, and safty of endoscopic submucosal dissection (ESD) in treatment of uppergastrointestinal ectopic pancreas. Methods 36 uppergastrointestinal ectopic pancreas were treated with ESD from January 1 2012 to November 30 2014. The definitive histological diagnosis of ectopic pancreas was made after the endoscopic treatment. We analyzed the operation method, dissected tissue, complication, retrospec-tively. Results 34 cases were located in stomach, the other 2 in duodenum. All cases underwent ESD, the mean op-erating time was 66 min. The mean dissected tissue diameter was 21 mm × 16 mm in the 36 cases. The curative re-section rate was 100.00 %. Bleeding rate of ESD was 2.77 %(1/36). Perferation rate of ESD was 2.77 %(1/36). 2 cases suffered from low grade fever. None need surgical intervention. Recurrence rate was 0.00%. Conclusions ESD is a minimally invasive technique that allows resection of whole lesions and provides precise histological information, which is particularly suitable for uppergastrointestinal ectopic pancreas.
