To explore the technical feasibility and clinical effect of assistant technique of laparoscopes for patients with colostomy.

From March 2009 to March 2015, fifty cases were randomly divided into two groups for laparoscopic colostomy (trial group, 25 cases) and conventional open colostomy (control group, 25 cases) in Zhongshan City People's Hospital. The following data of two groups were recorded: operation time (mean operative time, intraoperative blood loss), postoperative recovery (postoperative pain score, bowel function recovery time, hospital stay) and postoperative complications. The long-term survival of the two groups was evaluated after 1 year of follow-up.

All of the 50 patients underwent operations smoothly without intraoperative complications, postoperative bleeding or abdominal infection. In the trial group, 5 cases were transferred to the open abdomen; the average operation time and the amount of bleeding in the operation were slightly higher than those of the control group, but the difference was not statistically significant (t=0.625, 0.729, P=0.671, 0.823); the recovery time of gastrointestinal function was (3.5±0.5) d, and the average hospitalization time was (7.0±0.5) d, significantly shorter than those of the control group (4.7±1.5) d, (10.5±1.5) d (t'=3.795, 7.911, both P<0.01). The pain score of the patients in the trial group was significantly lower (U=3.502, P<0.01). After a median follow-up of 10 months, there were 5 cases of tumor recurrence, 42 cases of survival, 7 cases of anastomotic stenosis and re-anastomosis. No statistically significant difference was found in the incidence of anastomotic leakage and stenosis between the two groups ( χ²=0.166, P=0.684).

The application of laparoscopes in colostomy is safe and reliable, and it can significantly shorten the time of hospitalization and gastrointestinal function recovery with good clinical effect.
