Internal hernia with small bowel obstruction caused by Meckel's diverticulum: A case report.

We report a case of small bowel obstruction (SBO) caused by internal hernia from Meckel's diverticulum (MD). Abdominal CT scan showed an abnormal dilated blind-ending structure in continuity with the distal ileum in the right lower quadrant, suggesting Meckel's diverticulum. MPR images revealed a "double beak-sign" at the point of MD and a collapsed closed loop with mesenteric vessels converging to the diverticulum. Since the patient has no prior history of abdominal surgery, the diagnosis of internal hernia caused by Meckel's diverticulum was considered. On laparoscopic exploration, an abnormal orifice for internal hernia created by adhesion from the tip of Meckel's diverticulum to the adjacent mesentery was revealed, confirming the diagnosis. The patient was discharged after 7 days without postoperative complications. MD-associated internal hernia is a rare cause of small bowel obstruction and should be considered to avoid delay in treatment. Multidetector Computed Tomography (MDCT) is the first-line imaging modality of choice and may offer some suggestive imaging features to make an accurate preoperative diagnosis.
