A parastomal hernia is an incisional hernia related to an abdominal wall stoma. Parastomal hernia occurs frequently after the formation of a colostomy or ileostomy and it is the most common late stoma complication. Contents of parastomal hernia almost exclusively are limited to the mobile structures of the abdomen. Parastomal hernia including stomach is extremely rare. We describe a case of parastomal hernia containing stomach in a 65 year old woman who underwent rectal resection and left lower quadrant colostomy two years ago for rectal adenocarcinoma. The patient was presented to our emergency department with abdominal pain, vomiting and upper abdominal distension proceeding for 2 weeks. Abdominal CT revealed mild gastric dilatation associated with a parastomal hernia that contained the gastric corpus and antrum. The parastomal hernia was manually reduced. After 7 days, the patient fully recovered and was discharged. Parastomal hernia may contain stomach in patients presenting with obstructive symptoms. To the best of our knowledge, the current case has been published the ninth of such cases. Although rare, the present case is noteworthy in highlighting both the importance of being aware of this entity as well as radiologic confirmation to make correct diagnosis.
