Paracecal hernia due to membranous adhesion of the omentum to the right paracolic gutter

Abstract

Abstract Background Paracecal hernias, also known as pericecal hernias, are an exceptionally rare type of internal hernia. We report a unique case of paracecal hernia due to membranous adhesion of the omentum to the right paracolic gutter. Case presentation An 86-year-old female was admitted to our hospital with vomiting and abdominal pain. Laboratory findings showed a slightly elevated C-reactive protein level. Computed tomography scan showed dilated loops of the small intestine in the right paracolic gutter with medial displacement of the cecum and ascending colon. Internal hernia around the cecum due to postoperative adhesion after appendectomy was suspected, and she underwent emergency laparotomy. Intraoperative findings revealed the adhesion between the omentum and right paracolic gutter forming a cavity with the small intestine incarcerated. No abnormal adhesion in the ileocecal region was seen. We transected the omental adhesion from the orifice to the far end of the cavity near the hepatic flexure of the colon to release strangulation and to prevent recurrence. The patient was discharged on postoperative day 14 without complications. Conclusions Paracecal hernias have a type of membranous adhesion of the omentum to the right paracolic gutter. Surgeons should be aware of this paracecal hernia type, when they encounter the internal hernia.
