A surgical operation to make the pylorus larger, sometimes combined with treatment for peptic ulcers.
A surgical operation in which the outlet of the stomach (pylorus) is widened by a form of reconstruction. It is done to allow the contents of the stomach to pass more easily into the duodenum, particularly after ‘vagotomy to treat peptic ulcers (which would otherwise cause delay in gastric emptying).
Operation to repair or alter the pylorus, especially one to increase the caliber of the pyloric opening.
Pyloroplasty is a surgical procedure that involves enlarging the pylorus (the outlet from the stomach) to facilitate unrestricted passage of food into the intestine. This technique might be conducted as part of peptic ulcer surgery or to prevent constriction of the pyloric muscles following vagotomy (the surgical cutting of the vagus nerve to decrease stomach acid production).
