title: Outlet Obstruction of Temporary Loop Diverting Ileostomy.
abstract: Stoma formation is commonly performed in operations to treat carcinoma, inflammatory bowel disease (IBD) and familial adenomatous polyposis (FAP). In this study, we report several cases of stomal outlet obstruction and investigate the clinical features of cases of outlet obstruction in patients who underwent diverting loop ileostomy. Sixty-one patients with IBD, FAP or rectal cancer who required diverting loop ileostomy were identified for inclusion in this study. We defined outlet obstruction as a small bowel obstruction at the opening of the ileostomy following surgery. All cases of outlet obstruction were diagnosed by computed tomography. In the univariate analysis the type of diagnosis, type of operation, age, and white blood cell count were the factors significantly associated with outlet obstruction following ileostomy, and outlet obstruction was considered to have a connection with restorative proctocolectomy. In conclusion, we found that adhesion and twisting of the ileostomy were the causes of outlet obstruction. For temporary diversion, simple rotation of the ileostomy should be recommended, especially in restorative proctocolectomy. Additional study is required to explore other risk factors of outlet obstruction.
