肠梗阻是腹部外科术后最常见的并发症之一。全腹腔镜技术的应用使得肠梗阻的发生率大大降低，且以粘连型为主，仅有极少数病例需行手术治疗。腹腔镜右半结肠癌根治术后因系膜扭转诱发肠梗阻的病例未见报道。本病例术后40天左右出现肠梗阻，经保守治疗后缓解不明显，影像学资料并无肠系膜扭转征象，术中见回肠末端狭窄闭锁，吻合口周围小肠系膜部分扭转，行回结肠侧侧吻合后痊愈出院，较为少见。

Intestinal obstruction is one of the most common complications after abdominal surgery. The application of total laparoscopy greatly reduces the incidence of intestinal obstruction, and the main type of intestinal obstruction is adhesions, and only a few cases need surgical treatment. No case of mesenteric torsion induced intestinal obstruction after laparoscopic radical resection of right colon cancer have been reported. In this case, intestinal obstruction occurred about forty days after surgery, which was not significantly relieved after conservative treatment. Radiographic findings showed no signs of mesenteric torsion. During the operation, stenosis and atresia of the terminal ileum and partial torsion of the small mesentery around the anastomotic site were observed, which were relatively rare. Lateral anastomosis of the ileocolon was performed and the patient was cured and discharged.
