Intestinal Obstruction Due to Necrotic Torsion of a Meckel's Diverticulum: A Case Report in a Young Adult

Meckel’s diverticulum is recognized as the most prevalent congenital anomaly of the gastrointestinal system. While frequently asymptomatic, it can occasionally result in serious complications such as gastrointestinal hemorrhage, diverticulitis, or bowel obstruction. We present the case of a 20-year-old male who developed acute small bowel obstruction, initially resembling mesocoeliac appendicitis. Surgical intervention revealed a necrotic Meckel’s diverticulum twisted around a viable loop of ileum, creating an internal constrictive band and causing the obstruction. Treatment included segmental resection of the diverticulum, a double-barrel ileostomy, and peritoneal lavage. This case underscores the need to consider Meckel’s diverticulum as a differential diagnosis in intestinal obstruction, particularly among young adults with no prior abdominal surgeries.
