Abstract:
Objective To introduce a novel technique of intracolonic shunt procedure used in the anus - preserving operation for acute intestinal obstruction resulted from cancer at low and middle portions of rectum and assess the clinical significance. Methods In total, 81 patients with acute obstruction of low and middle portion of rectum caused by cancer were randomly ( random number) divided into control group and study group. In control group, 42 patients were operated with preventive transverse colonostomy or terminal ileum stoma after low proximal resection of rectum involved in cancer, while 39 patients were operated with intracolonic shunt procedure by using a biodegradable anastomosis ring and a condom placed 5 cm above anastomosis for protection in study group. Results There were no significant differences in sex, age, tumor site, tumor size and the distance from anstomosis to anal-edge between two groups. In both groups, the bowel movement resumed in 2 ~ 5 days after operation (P > 0.05). In study group, the rate of anastomosis leakage was 7.7% (3/39), and leakages were treated with drainage for 7.1 days in average to be healed, and the biodegradable anastomosis ring detached and were discharged in 14 -23 days (17 days in average), and there were no complications of drainage happened. The anastomotic stenosis occurred in three patients (7. 7% ) within 6 months after operation. In control group, 11.9% patients (5/42) had anastomosis leakage and they treated with drainage for 18.2 days in average to get the leakage healed, and 35. 7% patients (15/42) had stoma complications, and anastomotic stenosis happened in 28.6% patients (12/42) within 6 months after operation, and 7. 1% patients need another operation because of severe anastomosis stenosis. There were no significant differences in rate of anastomosis leakage between tow groups ( P > 0. 05), but there were significant differences in drainage days after anstomosis leakage happened and 6 - months anastomosis stenosis between two groups (P<0.05). Conclusions In the anus -preserving operation for acute intestinal obstruction at low and middle portions of rectum caused by cancer , the intracolonic shunt procedure is convenient and safty, and reduces the hazard incurred by anastomosis leakage and anastomosis stenosis compared with classic stoma operation.
