Jejunal pouch interposition after pylorus-preserving gastrectomy.

BACKGROUND

To improve the quality of life of patients undergoing gastrectomy, a nerve-conserving jejunal pouch was interposed after pylorus-preserving gastrectomy (PPG) with vagal nerve preservation. We report the details of the operative technique and the outcome.

METHODS

PPG with lymph node dissection was performed, preserving the hepatic, pyloric, and celiac branches of vagal nerve. The jejunum was cut approximately 20 cm distal to the ligament of Treitz. Marginal vessels were not divided in order to preserve the nerves in the jejunum that were used to construct the pouch. A linear stapler was used to perform a side-to-side jejunojejunostomy. A 12-cm-long pouch was formed by firing the stapler twice. The pouch was interposed between the residual parts of the stomach. Postoperatively, the patients were interviewed periodically. A dual-phase, dual-isotope radionucleid pouch-emptying study was performed 6 months after surgery.

RESULTS

A total of 13 patients underwent the operation. No complication developed. During the first 6 months after surgery, the body weight of the patients was maintained at 91% of the preoperative level. The radioisotope retention rate for the combined pouch and residual stomach was 46% for liquid food and 76% for solid food 120 min after ingestion. The pattern of its emptying was similar to that in healthy individuals.

CONCLUSIONS

The pouch-emptying test demonstrated a satisfactory retention capacity and acceptable emptying for the gastric substitute. A reasonably good quality of life has been obtained for patients undergoing PPG with interposition of a nerve-preserving jejunal pouch.
