摘要：

腹腔镜胰十二指肠切除术后输出袢梗阻罕见，其诊断较困难，严重影响患者预后及生存质量。本例患者因体检发现十二指肠腺癌就诊，行腹腔镜胰十二指肠切除术，术后第4天出现畏寒发热及呕吐含有胆汁胃内容物，经上消化道造影及胃镜证实胃肠吻合口输出袢梗阻。患者经保守治疗无效后二次剖腹探查行Braun吻合术，使消化液及胃内容物通过输入袢后经Braun吻合口到达远端空肠，从而解除输出袢梗阻，术后患者痊愈出院。该病例的救治经验证实了Braun吻合术治疗输出袢梗阻的有效性。而在腹腔镜胰十二指肠切除手术过程中，临床医生应尽量原位吻合，避免手术并发症的发生。

Abstract：

Postoperative output loop obstruction following laparoscopic pancreaticoduodenectomy is rare and difficult to diagnose, significantly impacting patient prognosis and quality of life. A patient was admitted for duodenal adenocarcinoma detected during a physical examination. After undergoing laparoscopic pancreaticoduodenectomy, the patient developed chills, fever, and vomiting of bile-stained gastric contents on the fourth postoperative day. Upper gastrointestinal contrast imaging and endoscopy confirmed an obstruction at the output loop of gastrointestinal anastomosis. After conservative treatment failed, a second exploratory laparotomy was performed with Braun anastomosis. This procedure allowed digestive fluids and gastric contents to pass through the afferent loop and then via the Braun anastomosis into the distal jejunum, thereby resolving the output loop obstruction. The patient recovered fully and was discharged. The management of this case confirms the efficacy of Braun anastomosis in treating output loop obstruction. Clinicians should prioritize in-situ anastomosis during laparoscopic pancreaticoduodenectomy to minimize surgical complications.
