Incarcerated and perforated stomach found in parastomal hernia: a case of a stomach in a parastomal hernia and subsequent strangulation-induced necrosis and perforation.

Parastomal hernias (PSHs) are a common type of incisional hernia and the most frequent complication to colostomies. Usually only mobile structures of the abdomen herniate in the hernial sac of the non-traumatic hernia. This case describes a large PSH adjacent to a lower left quadrant colostomy containing the mobile small intestine, part of the colon and a perforated stomach. The PSH presented with acute abdomen requiring explorative laparatomy and debridement. Large hernias may over time predispose to stretching of ligaments and mobilization of otherwise immobile structures with damage to these structures. The case report includes a short overview of hernia types associated with dislocation of the fixed organs of the abdominal space.
