Investigation of treatment methods in obstructive colorectal cancer.

ABSTRACT

PURPOSE: The aim of this study was to explore the treatment strategies for patients with obstructive colorectal cancer at different sites. METHODS: Treatment strategies were adopted according to the location of colorectal cancer and the condition of the patients when they were admitted to the hospital. Among a total of 134 patients, 29 patients were subjected to stent placement to relieve the obstruction before undergoing colorectal resection, 15 patients underwent per anum ileus catheterization to alleviate the symptoms of obstruction and waited for removal of the tumor within a limited time; 39 underwent intraoperative colonic lavage and colon resection with anastomosis and the remaining 51 patients were subjected to emergency surgery due to strangulation of the bowel, perforation, septic shock or other conditions before surgery. RESULTS: Stent placement was successfully performed on 23 patients, with a success rate of 79%. Ninety-five of 134 patients (71% had stage I anastomosis and only one case had anastomotic fistula. Infection of incision happened in 9 (7%) cases and 2 (1.5%) patients died of infection. CONCLUSIONS: Individualized treatment for patients with obstructive colorectal cancer can lead to tumor resection and stage I anastomosis, thereby avoiding the suffering of second-stage surgery or colostomy.
