    Abstract:
    BACKGROUND: Bezoars are large conglomerates of vegetable fibers, hairs, or concretions of various substances located in the stomach or small intestine of humans and certain animals, mainly ruminants. Gastrointestinal bezoars have constituted a relatively common clinical reality ever since the introduction of truncal vagotomy associated with drainage or gastric resection in the treatment of gastroduodenal peptic ulcer. STUDY DESIGN: This study presents a series of 87 cases of intestinal bezoar treated in our department of general surgery. Analysis was made of data obtained retrospectively from clinical histories, together with a clinical and endoscopic review of the patients. RESULTS: Most of the patients had had previous operative treatment (76.3 percent), the most commonly used technique being bilateral truncal vagotomy plus pyloroplasty (75.8 percent). An excessive intake of vegetable fiber was revealed in 39.5 percent of the cases, and alterations in dentition and mastication in 24 percent. Operative treatment was used in all patients. We attempted to fragment the bezoar and milk it to the cecum. Enterotomy and bezoar extraction were reserved for cases where fragmentation was impossible, as enterotomy was associated with more complications (p < 0.05). CONCLUSIONS: Bilateral truncal vagotomy plus pyloroplasty and a excessive ingestion of vegetable fiber are the main factors predisposing to bezoar formation. Clinically, intestinal bezoars manifest themselves in most cases as complete intestinal obstruction. Simple roentgenography of the abdomen is the fundamental technique for diagnosing the occlusive syndrome. Treatment must be operative, during which the bezoar is fragmented and milked to the cecum. The stomach must be explored for associated bezoars.
