Transverse, full-thickness incision in anterior wall of pylorus (1Ð2 cm on each side of pyloric ring) with double-layer longitudinal closure; requires full Kocher maneuver to avoid undue tension on suture line. Purpose is to aid gastric drainage after truncal or selective vagotomy has been performed or vagus nerve has been severed during esophagogastrectomy. Procedure should not be performed in presence of pyloric scarring or inflammation, and it makes pylorus nonfunctional after truncal vagotomy.
