During the past three years, we have seen gastric bezoars after partial gastrectomy in 5 patients. All had had a Billroth I gastroduodenostomy and truncal vagotomy. Gastric bezoars appear to be a new complication of gastric surgery, as previous reports that contained follow-up data on many patients have not mentioned this possibility (5, 9). Only recently have case reports appeared of gastric bezoars in patients with such operations. Of particular interest in the etiology of gastric pouch bezoars is a case reported by Olivier et al. (7), in which peptic ulcer difficulties continued after a Billroth II gastrojejunostomy. The anastomosis was therefore converted to a Billroth I gastroduodenostomy which, however, did not control the symptoms, and a marginal ulceration developed. A vagotomy was the third operative procedure. Five months later, gastric fullness, vomiting, and epigastric pain led to the discovery of a large gastric bezoar that required surgical removal. Borg et al. (1) reported 3 cases of massive yeast bezoars after Billroth I gastroduodenostomies. One of the patients had also undergone a bilateral vagotomy. Bezoars in the gastric pouch after Billroth II gastric resections, which passed into the small bowel and caused obstruction, have also been reported (6). Chun and Dinan (2) reported 4 cases with this complication, McCabe and Knox (4) reported 2, and Wilde (10) reported 3. The obstructing bezoar usually consisted of undigested cellulose contents such as citrus fruit, apple, or potato skins. Also worthy of note is the fact that in none of the cases of gastric bezoar reviewed n 1939 by DeBakey and Ochsner (3) had gastric resection been performed. This fairly new complication may easily be misinterpreted on study of the gastrointestinal tract. The filling defects in the pouch may be recognized but dismissed as being recently ingested food. The radiologic diagnosis can be established easily, but awareness of this possibility is important. The condition must be distinguished from neoplastic lesions, jejunogastric intussusception, and mechanical obstruction at the stoma. Case Reports Case I: A 52-year-old man had a Billroth I gastroduodenostomy and vagotomy on Sept. 22, 1954, because of peptic ulcer. The immediate postoperative course was uneventful. but two weeks later the patient complained of fullness and a heavy feeling in the abdomen. On radiologic examination, the stoma was not obstructed. Remnants of food were seen in the residual gastric pouch. Vomiting, epigastric pain, anorexia, and failure to gain weight led to rehospitalization five weeks after the operation. A large gastric bezoar was present (Fig. 1). No retention of fluid was noted within the stomach. Gastric lavage successfully broke up the bezoar. The patient was instructed carefully in regard to mastication and diet.
