What is the primary goal of a pyloroplasty?

The primary goal of a pyloroplasty is to enlarge the outlet of the stomach and relax the muscle at the pylorus, which is the opening from the stomach into the small intestine. This surgical procedure is performed to improve the passage of food from the stomach into the duodenum, facilitating digestion and helping to alleviate symptoms associated with gastric outlet obstruction. By relaxing the pyloric muscle, pyloroplasty enhances gastric emptying, thereby reducing symptoms such as nausea, vomiting, and abdominal discomfort that patients may experience due to a narrowed pylorus.

The other options do not accurately describe the purpose of the procedure. For instance, increasing stomach size or providing more space for digestion does not align with the specific, targeted aim of addressing pyloric obstruction. Additionally, removing part of the stomach is a different type of surgery, such as a gastrectomy, which is unrelated to pyloroplasty.
