What does pyloroplasty involve?

Pyloroplasty is a surgical procedure that involves the surgical enlargement of the pylorus, which is the opening from the stomach into the duodenum (the first part of the small intestine). This procedure is typically performed to relieve gastric outlet obstruction caused by various conditions, including ulcers or scarring. By enlarging the pylorus, the gastric contents can pass more freely into the duodenum, improving digestion and alleviating symptoms like vomiting and nausea associated with obstructive conditions.

The other options do not accurately describe pyloroplasty. For example, the connection between the esophagus and duodenum refers to an entirely different surgical procedure, such as an esophagogastroduodenostomy. Temporary cessation of bowel movement might occur in various surgical contexts but is not specific to pyloroplasty. Additionally, the direct connection of two bowel ends refers to anastomosis, a procedure distinct from the specific goal of pyloroplasty, which is focused on enlarging the pyloric channel rather than connecting segments of the bowel.
