Prolapse

Prolapse occurs at a rate ranging from 5.4 to 6.8%; one study quotes the incidence of prolapse in loop transverse colostomy as high as 47%. [23, 24] Prolapse can be easily seen on imaging as redundant bowel protruding through the ostomy site and hanging outside the body (Fig. 18.10). Stoma prolapse can be unsightly for the patient and also cause physical discomfort or pain. While most prolapses are asymptomatic and do not require any intervention, some can develop stenosis, strangulation, and/or obstruction. From a surgical standpoint, prolapse can be associated with or worsened by the presence of a PH. If the surgeon is planning an operative repair, then the prolapse will also need to be addressed at the time of the operation.
