目的 :探讨预防梗阻性左半结肠癌一期切除吻合术后吻合口漏发生的新方法。方法 :将梗阻性左半结肠癌一期切除吻合的病例 ,在肠道重建方面采用一层吻合加带蒂大网膜移植到吻合口上。结果 :12例手术患者未发现吻合口漏及腹腔脓肿。结论 :一层吻合加大网膜移植的方法 ,具有预防吻合口狭窄、改善吻合口血供、促进吻合口愈合及增加一层保护措施的作用 ,能有效预防及减少梗阻性左半结肠癌一期切除吻合术后吻合口漏的发生 Objective :To explore a new method to prevent anastomotic leakage after primary resection and anastomosis in obstructive left colon cancer. METHODS: One-stage resection and anastomosis of obstructive left colon cancer was performed. An anastomosis plus pedicled omentum was used to transplant the anastomosis in the reconstruction of the bowel. Results : There was no anastomotic leakage and abdominal abscess in 12 patients. Conclusion: One layer of anastomosis with omentum transplantation can prevent anastomotic stenosis, improve anastomotic blood supply, promote anastomotic healing, and increase a layer of protective measures. It can effectively prevent and reduce obstructive left colon cancer. Anastomotic leakage after resection and anastomosis
