Gastric remnant cancer after billroth II procedure

Six cases of gastric remnant cancer that occurred many years after Billroth II gastrectomy and gastrojejunostomy for benign disease are reported. They are classified as intestinal type and gastric type on the basis of their morphologic appearance. Their cytologic and histologic features are tabulated along with a summary of the clinical histories. Emphasis is placed on the possible high risk for patients with Billroth II procedures of developing cancer 10 to 25 years after surgery. Endoscopic follow‐up including cytologic study is essential to diagnose gastric remnant cancer in its early stage to secure a better prognosis.
