Abstract
The results of experimental work to measure the diameter of the pylorus during full
function are presented. This measurement was undertaken in the belief that adherence
to the strict physiologic diameter of the pylorus in anastomoses between the stomach
and duodenum or jejunum would serve to prevent the so-called dumping syndrome.
We found that this diameter never exceeded 1.9 cm which, we believe, represents the
normal threshold for gastric emptying without functional disturbances from the intestine.
Any increase in this diameter threshold involves a rather precipitous emptying of
the stomach contents into the intestine, which is the initiating factor in the dumping
syndrome.
This principle was applied in more than 1,300 gastroenteroanastomoses after gastrectomy
between 1954 and 1971, with the diameter never exceeding the limit of 2 cm. The technic
of the anastomosis and the surprisingly good functional results will be presented
in the second part of this work.
