Two Cases of Small Bowel Obstruction due to Gastric Bezoars after Selective Vagotomy and Pyloroplasty

Ileus due to intestinal incarceration of a postoperatively formed gastric bezoar is a very rare disease. We encountered two cases of ileus due to gastric bezoars formed after selective vagotomy and plyoroplasty (SV+P). Patient No.1 was a 57-year-old mart, who underwent SV + P for a duodenal ulcer 9 years earlier. In November of 1981, the patient experienced upper abdominal pain, nausea and vomiting and was hospitalized under a diagnosis of ileus. On Day 3 of hospitalization, an emergency operation was performed, and a goose-egg sized mass of foreign matter was found in the jejunum, and excized. Patient No.2 was a 54-year-old man who underwent SV + P for a duodenal ulcer 16 years earlier. In November of 1989, with the main complaint of abdominal pain, the patient was hospitalized under a diagnosis of ileus. By intestinal radioscopy, the disease was diagnosed as ileus due to intestinal foreign matter, and he was operated on Day 21 of hospitalization. A hen-egg sized mass of foreign matter was found in the ileum, and excised. In both cases, the foreign matter was believed to be a diospyrobezoar on the basis of constituent analysis.
