Perforated Sigmoid Diverticulitis Within a Strangulated Inguinal Hernia

Abstract

We present a rare case of perforated diverticulitis within an inguinal hernia sac adjacent to a synthetic mesh from a prior incisional hernia. An 80-year-old-female presented to the ED with abdominal pain. Cross-sectional imaging was significant for a small bowel obstruction with a transition point in the right lower quadrant (RLQ). On physical exam, the patient had palpable bilateral inguinal hernias that were reducible; however, after 48 hours of nonoperative management she failed to progress. Repeat imaging was concerning for incarcerated bowel within the inguinal hernia sac. She was taken to the operating room for exploratory laparotomy where the right inguinal hernia sac was found to contain sigmoid colon with diverticular perforation. A small bowel resection, right hemicolectomy and Hartmann’s procedure were performed. The previously placed synthetic mesh was not contaminated during this operation and was not removed. Her hospital course was otherwise unremarkable but prolonged by the patient’s deconditioned state.
