In this video, we present the laparoscopic technique of pancreas-preserving segmental resection for GISTs of the 4th portion of the duodenum. A 54-year-old male presented with a polypoid mass of about 3 cm in diameter with a large base, in the 4th portion of the duodenum, about 4 cm from the ampulla. Multiple endoscopic biopsies were taken, and all were negative for adenocarcinoma. CT scan of the abdomen confirmed that the mass, suggestive of GIST, was limited to the duodenum, a limited part intraluminal and the vast majority in the duodenal wall. A laparoscopic segmental resection with a 3D video system was accomplished. The operation lasted 160 min. Recovery was uneventful.

在本视频中，我们介绍了十二指肠第四部分胃肠道间质瘤的腹腔镜保留胰腺节段切除术。患者，男，54岁，十二指肠第4段距壶腹约4cm，发现一直径约3cm、基底较大的息肉样肿块。进行了多次内镜活检，腺癌均为阴性。腹部 CT 扫描证实，提示 GIST 的肿块仅限于十二指肠，有限部分位于管腔内，绝大多数位于十二指肠壁。使用 3D 视频系统完成腹腔镜部分切除术。手术持续了160分钟。恢复过程很顺利。
