K43.5: Parastomal hernia without obstruction or gangrene

Parastomal hernia without obstruction or gangrene is a medical condition that occurs when a part of the intestine or fat pushes through a weakened area in the muscles of the abdomen around an existing stoma. A stoma is a surgically created opening in the abdominal wall, often created as part of a colostomy or ileostomy. This condition does not involve any blockage (obstruction) of the intestine or tissue death (gangrene). Symptoms may include a bulge or swelling around the stoma, discomfort, and changes in the function or appearance of the stoma, such as increased size or prolapse. Despite these symptoms, some people may not notice any discomfort or visible changes. The progression of the condition often involves an initial small bulge that enlarges over time. While the hernia itself is not life-threatening, potential complications can occur, making immediate medical attention crucial if symptoms worsen or if significant changes occur.
