Modified Heineke-Mikulicz pyloroplasty as an effective gastric drainage procedure.

Rats were prepared with modified Heineke-Mikulicz pyloroplasty with longitudinal seromuscular incision, centering at pyloric ring, separation of submucosal layer around the pylorus and addition of transverse closure. This procedure combined with vagotomy was applied to the rats with cortisone administration and obstructive jaundice or exposure to the restraint plus cold water stress. Pyloroplasty and vagotomy seemed to prevent the occurrence of the severe damage on gastric mucosa without any suture line leakage whereas. Control rats had often erosive gastritis or hemorrhage.
