Jejunal pouch interposition with an antiperistaltic conduit as a pyloric ring substitute after standard distal gastrectomy: a comparison with the use of an isoperistaltic conduit.
OBJECTIVE
We performed jejunal pouch interposition with a short antiperistaltic conduit as a pylorus substitute after gastrectomy for gastric cancer and compared the outcome with an isoperistaltic conduit.


METHODS
After a standard distal gastrectomy and lymph node dissection, a 15-cm-long pouch was formed using 3 linear staples (Endo-GIA) and interposed between the residual stomach and duodenum. The distal jejunal limb was made into a 3-cm-long isoperistaltic conduit in the isoperistaltic group (n = 17), and the proximal jejunal limb was made into a 3-cm-long antiperistaltic conduit in the antiperistaltic group (n = 8). Postoperatively, the patients were interviewed periodically to document any complaints. A dual-phase, dual-isotope radionuclide gastro-pouch-emptying study was performed 1 and 6 months after surgery.


RESULTS
None of the patients developed postoperative complications and showed discomforts of dumping, stasis or reflux esophagitis. The dietary volume and body weight of patients gradually increased in both groups after 6 months. The combined radioisotope retention rate for the pouch and residual stomach was 31% for liquid food and 35% for solid food in the isoperistaltic group after 120 min, and 41% and 57%, respectively, in the antiperistaltic group. The pattern and emptying rate for solid food in the antiperistaltic group were more similar to those in healthy individuals than in the isoperistaltic group.


CONCLUSIONS
The gastro-pouch-emptying test in the antiperistaltic group demonstrated acceptable emptying for a pyloric ring substitute. A reasonably good quality of life has been obtained for patients having an antiperistaltic jejunal conduit.
