Which procedure involves creating an opening into the stomach for medical purposes?

The procedure that involves creating an opening into the stomach for medical purposes is gastrojejunostomy. This is often performed to allow for direct access to the stomach for feeding, especially in patients who are unable to eat by mouth due to various medical conditions. The creation of this opening, or stoma, enables nutrient delivery and can be essential for the management of chronic illnesses or post-operative care.

Gastroscopy, while involving examination or intervention within the stomach, does not create a permanent opening; it typically utilizes instruments inserted through the mouth to visualize or treat conditions within the stomach. Laparotomy refers to a surgical procedure involving a large incision in the abdominal wall to access the abdominal cavity for various purposes, but it does not specifically involve creating an opening in the stomach itself. Appendectomy pertains specifically to the removal of the appendix and does not involve the stomach at all.

Thus, gastrojejunostomy is the only option that directly correlates to the act of creating a permanent access point into the stomach for ongoing medical treatment or intervention.
