RESUMO
Objective To analyze the outcome of patients with acute obstruction of left colorectal cancer treated by modified antegrade colonic lavage with primary tumor resection and anastomosis.Methods From April 2002 to April 2007,112 patients with acute obstruction of left colorectal cancer underwent surgery.During the operation the left colon was exteriorized and placed into a sterilized plastic bag to protect the surgical field from contamination,then a catheter was inserted via the appendix,and after antegrade colonic lavage,primary resection and anastomosis was performed.Results Tumor resection and primary anastomosis was successfully done in the 112 cases.Postoperatively,1 case had anastomotic leak which healed after reoperation with proximal colostomy,and one patient died.Conclusions Modified antegrade colonic lavage is a simple procedure,the bowel can be rapidly decompressed with essentially no contamination,and has a high level of bowel cleansing.It is possible to safely perform primary resection and anastomosis for left colon cancer after the modified antegrade lavage.
