根部结扎肠系膜下血管在乙状结肠癌根治术中的意义

目的探讨乙状结肠癌根治术中于根部结扎肠系膜下血管的合理性。方法回顾性分析2005年12月~2006年12月间30例行乙状结肠癌根治术病例资料,手术时于根部切断结扎肠系膜下血管,注意保护内脏神经的腹主动脉丛和上腹下丛,分析肠系膜淋巴结转移和手术并发症情况。结果本组淋巴结转移者8例(26.7%),其中肠系膜根部有转移者3例(10.0%)。合并梗阻者一期切除吻合后有2例发生吻合口瘘,经引流等非手术治疗治愈,无手术死亡病例。结论乙状结肠癌根治术从根部处理肠系膜下血管合理可行。

High Ligation of the Inferior Mesenteric Vessel in Sigmoid Colon Cancer Radical Resection

Objective To evaluate the rationality of high ligation of the inferior mesenteric vessel(IMV) in sigmoid colon cancer operations.Methods 30 sigmoid colon cancer patients underwent radical resection admitted from December 2005 to December 2006 were retrospectively analyzed.During operation,the IMV was ligated at the root and visceral nerves were preserved.The metastasis state of lymph node in mesentery was analyzed postoperatively.Results 8(26.7%) patients had mesentery lymph node metastasis,and 3(10.0%) had metastasis at the root of IMV.Anastomotic fistula occurred in 2 intestinal obstruction cases that underwent one-stage anastomosis,and healed later by drainage.No operative fatality occurred.Conclusion It is safe and reasonable to ligate the IMV at the root in sigmoid colon cancer surgery.
