The surgical procedure that involves the excision of the pylorus is known as pylorectomy. This procedure specifically targets the pylorus, which is the section of the stomach that connects to the small intestine. By removing the pylorus, the operation addresses issues such as pyloric stenosis, ulcers, or malignancies in that region.

In contrast, pyloroplasty refers to the surgical technique that widens the pylorus but does not involve removal; gastrojejunostomy entails creating an anastomosis between the stomach and jejunum, bypassing the pylorus entirely; and cholecystectomy is the removal of the gallbladder, which is unrelated to the pylorus. Understanding the specific goals and techniques of these various procedures highlights why pylorectomy is distinctly characterized as the excision of the pylorus.
