A rare case of acute abdomen caused by diverticulum perforation in the jejunum

Diverticulitis of the small bowel is a rare condition that is typically asymptomatic. This study presents a case of diverticulitis of the jejunum in a 70-year-old male. The patient presented to our clinic with acute abdominal pain. Abdominal CT revealed the presence of a diverticulum in the jejunum with mesenteric air and fat stranding. Due to clinical deterioration, the patient was taken to the operating room for surgical exploration. Exploratory laparoscopy revealed multiple diverticula in the proximal jejunum over a length of 50 cm, with signs of diverticulitis in one segment. The laparoscopic procedure was converted to an open approach. A segmental resection of the small bowel was performed, which included the inflamed portion and most of the diverticulum. Laparoscopy and laparotomy are both recommended for managing complications associated with diverticulitis in the jejunum. In cases with complications such as perforation and abscess formation, segmental resection is the preferred approach.
