The vagotomy develops the hypotonic stomach, myoelectrographic delay of propagation velocity and the pyloric spasm secondary to the rise of intragastric pressure. Even by SPV, the weakness of motility of the antrum was observed by myoelectrography and gastric emptying.
The transection developed a marked excitation of the antral-pyloric portion, and the degree of excitation enlarged as the transection was done nearer to pylorus.
While, intrapyloric pressure increased at the level of transection from upper third stomach to 2.0cm apart from pyloric ring, however, the pressure was kept same degree as that of intact stomach when the transection line was placed at 1.5－1.0cm apart from pyloric ring.
Pylorus preserving gastrectomy was originated upon these phenomena, and it is useful to understand these phenomena for the adaptation of drainage procedure, too.
In case of both vagotomy and transection were done at the same time, transection produced a powerful effect on the antral-pyloric motility, compaired with vagotomy. This suggeseed that the excitation of antral-pyloric portion developed by transection was not able to be controlled by preservation of ‘Latarjet’ nerve alone.
