Torsed gangrenous Meckel’s diverticulum causing gangrenous ileal segment: A rare case report of small bowel obstruction in children

INTRODUCTION: Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal system. It is caused by an incomplete obliteration of the vitelline duct. Rarely, it can present with complications like torsion and gangrene formation. CASE PRESENTATION: A 13-year previously healthy girl presented with sudden onset periumbilical pain and bilious vomiting who was subsequently diagnosed with Meckel's diverticulum. Intraoperatively, torsed gangrenous diverticulum forming band adhesion was found. Resection of Meckel's diverticulum along with gangrenous ileal segment followed by ileoileal anastomosis was done. DISCUSSION: Axial torsion of Meckel's diverticulum with gangrene formation is a rare occurrence. Mesodiverticular band adhesion along with herniation of small bowel segments under it endangers viability of herniating segments. Preoperative diagnosis of complicated MD is difficult as it mimics other common acute abdominal conditions. CT scan and enteroclysis are imaging modalities of choice. Surgical resection of MD along with resection and anastomosis of gangrenous bowel segment results in complete cure. CONCLUSION: Meckel's diverticulum with complications should be kept in the differential of acute abdominal conditions presenting with atypical symptoms. Surgical resection ensures complete cure.
