A rare cause of acute abdomen: small bowel obstruction due to phytobezoar.

BACKGROUND Phytobezoars are a rare cause of acute small bowel obstruction. The aim of this work was to identify the diagnostic difficulties and treatment of this rare entity. METHODS Data of 14 patients operated between January 1999-January 2009 with small bowel phytobezoar were retrospectively studied. The patients (n=432) were treated in our clinic for small bowel obstructions. Of these, 14 (3.2%) phytobezoar-induced small bowel obstructions were included in this series. Median patient age was 57.25 years; nine (64%) of the patients were male, and five (36%) were female. RESULTS The predisposing factor was previous gastric surgery in 12 (87.5%) patients and previous abdominal surgery and total absence of the teeth in two (14.3%) patients. A completely obstructing terminal ileal phytobezoar was found in nine (64%) patients and jejunal phytobezoar in five (36%) patients during exploration. There was no mortality. CONCLUSION Phytobezoar-induced small bowel obstruction remains an uncommon diagnosis that poses a diagnostic and management challenge. It should be suspected in patients with an increased risk of bezoar formation, such as in the presence of previous gastric surgery, poor dentition or a history suggestive of increased fiber intake.
