A CASE OF MULTIPLE GASTRIC CANCER CAUSED BALL VALVE SYNDROME

Abstract

Ball valve syndrome is defined as clinical phenomenon in which the sudden obstruction of the lumen of the pylorus by a gastric tumor intussusception. We report a rare case of Ball valve syndrome in which one lesion of multiple gastric cancer prolapsed into the duodenal bulb. A 76-year-old bedridden man with cerebral infarction was referred because of abdominal fullness and vomiting. Gastrointestinal endoscopy showed the irregular, double-headed polyp with the long, wide stalk on the greater curvature of the pyloric antrum. Another two protruding lesions on the posterior wall of the upper corpus and the anterior wall of the ventricular angle were also shown. UGI series demonstrated prolapse of a large pedunculated polyp which consisted of 2 parts, through the pylorus into the duodenal bulb. Biopsy specimens taken from these lesion were diagnosed as gastric cancer. Resection of the tumors was performed. After treatment, his symptoms were resolved. Because of elderly patients who have complicated disease with deteriorated Activities of Daily Living, local resection seemed to be one of the treatment for this case.
