Acute Jejunal Diverticulitis With Abscess Formation Complicated by Perforation: A Case Report

Jejunal diverticulum perforation is a rare condition and presents diagnostic challenges. A 41-year-old male presented to the emergency room with a history of vague, generalized, and continuous abdominal pain for two days. He was vitally stable; however, the abdominal examination revealed a soft and distended abdomen with positive rebound tenderness. A computed tomography scan with contrast showed signs of a perforated proximal jejunal segment, along with adjacent pneumoperitoneum and a small fluid collection. The patient underwent diagnostic laparoscopy, which was converted to a midline laparotomy for further exploration of the small bowel. An 8-cm jejunal diverticulum with micro-perforation and abscess was identified during the procedure. The pathological diagnosis confirmed acute diverticulitis with abscess formation, and malignancy was ruled out. The patient remained stable throughout his postoperative recovery and was discharged on the sixth postoperative day.
