Transpyloric prolapse of polypoid gastric carcinoma.
Four patients with discrete intraluminal filling defects in the duodenal bulb secondary to transpyloric prolapse of polypoid gastric carcinoma are reported. The lesions were pedunculated in 2 cases and sessile in the remaining 2. The clinical, radiological,and pathological findings are discussed. Prolapsed gastric carcinoma should be included in the differential diagnosis of localized intraluminal filling defects in the duodenal bulb and endoscopy and biopsy performed in patients with appropriate clinical and radiological findings.
