Efferent Loop Stimulation Previous to Ileostomy Closure. Ileostim Trial.

The loop ileostomy is an effective method used to bypass faecal contents and reduce the sequelae of possible anastomotic leakage. I t is most often performed after a low anterior resection indicated for lower-middle rectal cancer. A second operation is required for closure, with a morbidity of about 25%. Many studies have been completed in order to detect possible risk factors - both patient-related and surgery-related - for complications in ileostomy closure surgery. Currently, there is a lack of research studies focused on the preoperative management of these patients. Our purpose is to reduce the complication rate by optimizing the preoperative status of the distal ileum and to analyze its impact on the reduction of postoperative ileus. Main objective: To assess whether efferent loop stimulation two weeks before ileostomy closure decreases the incidence of postoperative paralytic ileus.
