BACKGROUND AND OBJECTIVE: Most surgeons suggest the use of fecal diversion in @entity1 undergoing low anterior resections of @entity5 at high risk for @entity834 . We describe an exploratory study to evaluate the efficacy and safety of a new diversion method called a spontaneously closing cannula ileostomy, which was designed to protect rectal anastomoses in @entity1 at high risk for @entity834 . The outcomes of @entity1 treated with cannula ileostomy were compared to those of @entity1 treated with loop ileostomy. MAIN OUTCOME MEASURES: Outcomes included the rates of @entity834 , reoperation and other complications, as well as length of hospital stay and cost. DESIGN AND @entity1 : From January 2011 to December 2012, 294 @entity1 undergoing low colorectal or coloanal @entity254 were treated with ileum diversion using cannula ileostomy or traditional loop ileostomy. Demographics, clinical features, and operational data were recorded. RESULTS: The @entity834 rates were 8.1% (12/149) in the cannula ileostomy group and 8.3% (12/145) in the loop ileostomy group (p = 1.0). The reoperation rate was 3% (4/149) in @entity1 treated with a cannula ileostomy and 3.4% (5/145) in those who underwent a loop ileostomy (p = 0.75). The median length of the hospital stay was 8.6 days in the cannula ileostomy group and 17.1 days (p < 0.01) in the loop ileostomy group, including time for the initial and reversal operations. In the cannula ileostomy group, the median time to defecation from the anus was 16.5 days after the operation. During the follow-up period, 13 @entity1 in the loop ileostomy group retained their stoma, as compared to 2 in the cannula ileostomy group (p < 0.01). LIMITATIONS: This study was a nonrandomized design and lacked contrast enema data to identify @entity834 . CONCLUSIONS: Cannula ileostomy is a safe and effective diverting technique that protects low colorectal and coloanal anastomoses. @entity1 receiving a cannula ileostomy had shorter hospital stays and lower rates of permanent stoma than those receiving a loop ileostomy.
