Endoscopic resection of descending duodenal polyp with the string-clip traction.

There is few studies about modified endoscopic treatment of duodenal lesions. The string-clip method is an effective option for large pedunculated duodenal polyp. On the one hand, it could increase the tension of the lesion and make endoscopic resection easy. What is more, with the help of clip and dental floss, we do not have to worry about specimen losing. We could deal with the wound first and then retrieve the resected specimen, resulting in an increased safety and efficiency of the endoscopic treatment.
