In which procedure is a connection established between the stomach and the intestines?

The procedure that establishes a connection between the stomach and the intestines is gastroenterostomy. This surgical procedure involves creating a new passageway between the stomach and the jejunum, which is part of the small intestine. This connection allows for food to bypass a part of the digestive tract, often used in cases where there are obstructions, ulcers, or other gastric issues that necessitate such a diversion to ensure proper digestion and nutrient absorption.

In contrast, gastric bypass primarily refers to a type of weight-loss surgery that alters the stomach and intestines in a way that reduces the amount of food the stomach can hold and changes the way nutrients are absorbed, but it is not solely about creating a direct connection between the stomach and intestines. Gastrostomy is a procedure in which an opening is created from the stomach to the abdominal surface, allowing for feeding directly into the stomach without involving the intestines. Pyloroplasty is a surgical procedure that involves widening the opening (pylorus) between the stomach and the small intestine to improve gastric drainage but does not directly connect the stomach to the intestines in the way gastroenterostomy does.
