Proximal gastrectomy and jejunal pouch interposition for the treatment of early cancer in the upper third of the stomach: Surgical techniques and evaluation of postoperative function

Background. Limited surgery for the treatment of early gastric cancer located in the upper third of the stomach should be based on a well-balanced reduction in the extent of lymph node dissection and gastric resection while assuring a favorable quality of life and prognosis after operation. Methods, We have used interposition of a double jejunal pouch between the esophagus and the remnant stomach after performing proximal gastrectomy. To assure anastomosis and hemostasis during this operation we currently use a surgical stapler with a vaginoscope and our new edge clamps. This method has been used in 12 patients to date. Results, On histopathologic examination the 12 cases comprised 11 early cancers (seven mucosal and four sub-mucosal cancers) and one subserosal cancer There was no evidence of lymph node metastasis or postoperative complications such as anastomotic leakages or hemorrhage, demonstrating the low-risk nature of this procedure. Conclusions. The evaluation of postoperative quality of life, in terms of clinical signs and symptoms and dietary status, yielded favorable results. Thus our method has the important advantage of allowing good organ preservation.
