“Stomal necrosis has been reported to occur in up to 20% of ostomates in the immediate postoperative period ([Fig. 1]). Specific risk factors for stoma necrosis include emergent operation, inadequate mobilization of the bowel, excessive mesenteric resection resulting in inadequate arterial blood supply to or venous drainage from the bowel, and constriction in the abdominal wall due to excessively small openings in the fascia, abdominal wall mesh, or skin.  Importantly, the obese patient is seven times more likely to experience stoma necrosis than the nonobese patient. Stoma necrosis is much less common for loop stomas given the dual blood supply to both the afferent and efferent limbs.”
