Evaluation of reconstruction after proximal gastrectomy: prospective comparative study of jejunal interposition and jejunal pouch interposition.

BACKGROUND/AIMS To prevent various distresses after proximal gastrectomy, reconstruction by interposed jejunal pouch has been advocated as an organ-preserving surgical strategy to ensure favorable quality of life for the patients. METHODOLOGY Proximal gastrectomy was performed in 9 patients with gastric cancer in the upper third of the stomach. Four patients were randomly selected for reconstruction by jejunal pouch interposition (JPI group), while 5 had reconstruction by jejunal interposition (JI group). The patients who underwent JPI and JI were followed up to evaluate resumption of normal diet, change in body weight, and clinical symptoms. RESULTS The JPI group showed a significant dietary advantage. Three months after surgery, JPI patients could eat more than 80% of the volume of their preoperative meals, whereas JI patients ate less than 50%. The percentage of postoperative body weight loss was higher in the JI group than in the JPI group because the volume of the remnant stomach was more adequate in the latter. Moreover, it was easier to enter the remnant stomach and duodenum for endoscopic fiberscopy in the JPI group for the treatment of hepato-biliary pancreatic disease. CONCLUSIONS JPI is an effective method for preservation of gastric function after proximal gastrectomy.
