INTRODUCTION: Meckel's diverticulum (MD) is the prevailing anomaly of the gastrointestinal tract, found in about 2% of the population; it rarely gives rise to symptoms and its discovery is usually accidental. Phytobezoar is a concretion of poorly digested fruit and vegetable fibres that is found in the alimentary tract and rarely can be the cause of small intestinal obstruction. Herein we report a rare case of intestinal obstruction due to phytobezoar formation into a MD.

PRESENTATION OF CASE: A 50 year-old patient, was admitted to author's institution with an history of abdominal pain, nausea and multiples episodes of vomiting. Plain X-ray showed dilated small-bowel loops. Computed tomography (CT) revealed jejunal loops with air-fluid levels. The patient underwent explorative laparotomy where we found a giant Meckel's diverticulum, filled by a phytobezoar that caused small bowel compression. We performed a segmental ileal, resection, containing the MD. The histological exam confirmed Meckel's diverticulum.

DISCUSSION: Bowel obstruction due to a phytobezoar in a Meckel's diverticulum is rare: only 7 cases have been reported in literature. MD complications are rare and phytobezoar is one of them with only few cases described in literature.

CONCLUSION: The conventional x rays studies were inconclusive whereas abdominal contrast enhanced CT led to a definitive diagnosis. Explorative laparotomy or laparoscopy is mandatory in these cases.
