Abstract
Background: Total gastrectomy with D2 dissection is the standard treatment in Japan for early upper-third gastric cancer. The purpose of this study was to confirm the safety and radicality of proximal gastrectomy as an alternative operation. Methods: Between 1993 and 1999, 45 patients with an apparent primary early gastric cancer in the upper third of the stomach were treated by proximal gastrectomy with jejunal interposition. The spleen was preserved, but the suprapancreatic nodes were cleared. Results: Histology confirmed early gastric cancer in 37 patients while eight had advanced disease. Nodal metastasis was observed in six patients. There was no hospital death and no early postoperative complications. One patient died from nodal recurrence and two from unrelated causes. Two patients had reflux symptoms without endoscopic oesophagitis. Mean weight loss was 11·5 per cent of initial bodyweight. Conclusion: Proximal gastrectomy for early upper-third gastric cancer can be performed safely with an excellent cure rate. This procedure deserves further clinical evaluation to assess patients' quality of life.
