diverting ileostomy
Temporary surgical diversion of small bowel contents to protect a distal anastomosis.
Full Definition
A diverting ileostomy is a temporary surgical procedure that redirects the flow of intestinal contents away from a distal anastomosis to allow proper healing. This is commonly performed during low anterior resection for rectal cancer or other pelvic procedures where anastomotic complications could be catastrophic. The ileostomy is typically created in the right lower quadrant and can be reversed 6-8 weeks after the initial surgery once anastomotic integrity is confirmed. The procedure significantly reduces the morbidity associated with anastomotic leakage in high-risk patients.
