Jejunal diverticulosis complicated with perforation: A rare acute abdomen etiology

Introduction: Jejunal diverticulosis is a rare intestinal pathology with an incidence of 0.5-1%. While most cases are asymptomatic, 30-40% of the cases may become symptomatic with chronic abdominal pain, malabsorption, hemorrhage, diverticulitis, obstruction, abscess formation and, rarely, diverticula perforation. It is generally localized on the mesenteric side and it develops from the entry points of the vessels into the jejunum.

Case presentation: Case 1 - A 36-year Case 2 a 75 old female patient patient was admitted to the emergency department with the complaint of widespread abdominal pain, Case 1 8 diverticules, one with diverticule perforation, was observed in the jejunum segment between the 50th and 90th centimeters after the Treitz Ligament. Case 2 - In the diverticulum 100 cm distal from the Treitz ligament, mesenteric perforation area of 4-5 mm were observed.

Results: Segmentary small bowel resection and side-by-side anastomosis were performed in these cases. In the histopathological examination, the Diverticula were seen to be pseudodiverticullar lesions including herniation of the mucosa and submucosa.

Conclusion: Jejunoileal diverticulosis is a rare disease with life-threatening complications such as perforation, obstruction and bleeding, it is usually asymptomatic or presents with nonspecific symptoms. It should be considered in the differential diagnosis of acute abdomen.
