| Abstract |
PURPOSE
Divided end-loop colostomy is recommended in some cases of unresectable rectal cancer or anal incontinence, because a conventional loop colostomy is difficult to managing due to bulky stoma volume for a long period. In such case of the divided end-loop colostomy, severe inflammation may occur at the stoma site by poor conditions of the patient so that cause to be retracted or detached, and distal loop may be disrupted. To avoid these problems, we designed subtotally divided end-loop colostomy and studied its clinical effectiveness retrospectively.
METHODS
About a 3 cm diameter, round skin incision as presumed colostomy size was made at the left lower abdomen, and entered the abdominal cavity by splitting the rectus muscle fibers. The caudal side of colon can be identified by confirming the fusioned taenia at the rectosigmoid colon level. After pulling out the colonic loop, the distal colon far from the lesion was subtotally divided by a GIA staple or manual suture, which cut obliquely 80% or 90% from the antimesenteric side of the distal loop while maintaining the 10% or 20% mesenteric side of the colonic loop. Then an end-loop colostomy is matured with a small fistularization of the distal loop as the undivided mesenteric side of colon.
RESULTS
In 8 cases, subtotally divided colonic loop using a GIA staple. But in 9 cases, divided manually because of makedly thickened, edematous colonic wall resulting from prolonged obstruction. There were several mild complications, i.e. transient dermatitis in 5 cases, transient bulky stoma due to edema in 4 cases, mild retraction of stoma in 2 cases, and mild prolapse of stoma in 1 case. There were no major functional abnormalities during the follow-up period.
CONCLUSIONS
Although we need to get further clinical experiences, the subtotally divided end-loop colostomy seems to be a useful alternative surgical procedure for unresectable rectal cancer. |
