Abstract
Introduction: Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. Intussusception secondary to MD is rare in adults and often presents with bowel obstruction.
Case presentation: We report a case of a 45-year-old female patient with no prior medical history who presented with five days of abdominal pain, vomiting, and cessation of feces and gas. Physical examination revealed diffuse abdominal tenderness with mild distension. Laboratory tests showed an inflammatory syndrome (WBC: 9,400/µL, CRP: 21 mg/L). Abdominal CT revealed small bowel obstruction with a distended ileum and jejunum. Urgent laparotomy revealed an ileo-ileal intussusception 10 cm from the ileocecal valve. A 20-cm segment of small bowel including the intussusception was resected, followed by manual end-to-end anastomosis. The specimen contained Meckel’s diverticulum, confirmed by histopathology. The patient recovered well postoperatively.
Conclusions: Adult intussusception due to MD is rare and challenging to diagnose preoperatively. Segmental bowel resection with anastomosis is the treatment of choice to prevent complications and ensure complete removal of ectopic mucosa.
