Gastric emptying. A comparison of the Heineke-Mikulicz and Finney pyloroplasties with the Ramstedt pyloromyotomy.

Roentgenographic complete gastric emptying times using dilute barium were measured in 31 conditioned mongrel dogs (1) under normal or basal conditions, (2) after subdiaphragmatic complete truncal vagotomy, and (3) after four different methods of gastric drainage. The drainage procedures in 24 dogs were divided into four groups of six dogs each: (1) Heineke-Mikulicz two-layer (HM1) pyloroplasty; (3) Finney pyloroplasty (FP); and (4) the Ramstedt pyloromyotomy (RP). Using the same protocol for measuring complete gastric emptying, a fifth group of seven dogs underwent two gastric drainage procedures each: RP followed by subsequent conversion to the HM1. The statistical comparison to these procedures for adequacy of gastric drainage demonstrated no significant differences or superiority of any procedure in the groups of animals tested.
