Which procedure is performed to remove the stomach?

The procedure performed to remove the stomach is a gastrectomy. This surgical operation involves the complete or partial removal of the stomach and is typically indicated for conditions such as stomach cancer, ulcers, or severe obesity. During a gastrectomy, the surgeon can remove either the entire stomach, known as total gastrectomy, or just a portion of it, referred to as partial gastrectomy.

In contrast, the other procedures listed have different purposes: an appendectomy is the surgical removal of the appendix, fundoplication is a procedure to treat gastroesophageal reflux disease (GERD) by wrapping the top of the stomach around the esophagus, and herniorrhaphy is a surgical repair of a hernia. Each of these procedures addresses specific medical conditions and involves different surgical techniques, which clarifies why gastrectomy is the correct answer for the removal of the stomach.
