title: A report of 15 cases of small-bowel obstruction secondary to phytobezoars: predisposing factors and diagnostic difficulties.
abstract: Phytobezoars are a rare cause of acute bowel obstruction. The purpose of this work was to identify the predisposing factors and diagnostic difficulties of this rare entity.
  
  
  METHODS
  This was a retrospective study including all cases of small-bowel obstruction secondary to phytobezoars observed between April 2001 and August 2007. The diagnosis of bezoars was established by surgical exploration or by computed tomography (CT).
  
  
  RESULTS
  During the study period, 375 patients were hospitalized at our institution with a diagnosis of bowel obstruction that, in 15 (4%) cases, was secondary to phytobezoars. The average patient age was 55 years, with a gender ratio of 1.7, favoring men. The predisposing factors were gastroduodenal surgery for peptic ulcer in nine patients, and excessive consumption of prickly pears (cactus figs) in 12. The diagnosis was established by CT scans in three patients, who were successfully treated with gastric aspiration, thereby avoiding surgery. Laparotomy was performed in 12 patients to allow digital fragmentation of the bezoar, which was then washed into the colon. There were no postoperative deaths and morbidity was about 13%.
  
  
  CONCLUSIONS
  An abdominal CT scan should be obtained for patients with small-bowel obstruction. This examination offers a precise diagnosis of bezoars, reducing the number of unnecessary surgical procedures, and helping to guide the approach if surgery is needed.
