A case report of small bowel occlusion due to Meckel diverticulum causing a life-threatening condition

INTRODUCTION AND IMPORTANCE: Meckel's diverticulum is a common congenital abnormality. In this study, we reported a case of small bowel occlusion due to Meckel's diverticulum causing a small bowel obstruction and a life-threatening condition. CASE PRESENTATION: 28-year-old man complaining of abdominal pain for 3 days. The physical examination found the patient appeared profusely unwell with a blood pressure of 80/40 mmHg. The abdominal examination found abdominal rigidity suggesting peritonitis. The patient's C-reactive protein was 210 mg/l with normal white blood cell count. Consequently, the patient was operated on using a laparotomy. A mechanical bowel obstruction due to a gangrenous Meckel's diverticulum was confirmed during the operation. Meckel's diverticulitis with the tip attached to the ileal mesentery through a band. A section of the band was performed followed by a resection of the Meckel's diverticulum and an ileo-ileal anastomosis. The postoperative follow-up was uneventful. Case discussion: Meckel's diverticulum results from yolk sac persistence during embryonic development, often remaining asymptomatic. However, it can lead to symptoms like abdominal pain, diarrhoea, and fever when inflamed or infected. Treatment involves surgery (diverticulectomy) for severe cases with complications, with good prognosis but associated surgical risks. CONCLUSION: The diverticulum can present a life-threatening condition. The treatment is essentially surgical. This surgery should be performed emergently to enhance the prognosis.
