Which term refers to the surgical procedure of suturing the abdomen?

The surgical procedure for suturing the abdomen is specifically referred to as gastropexy. Gastropexy is a technique commonly used to attach the stomach to the abdominal wall to prevent conditions such as gastric torsion or bloat, which can be life-threatening.

In contrast, herniorrhaphy is the surgical repair of a hernia, where tissue protrudes through an abnormal opening. While it also involves the abdomen, it is not a direct procedure for suturing the abdomen itself.

Nephrectomy is a surgical procedure that involves the removal of a kidney, which is not related to suturing the abdomen.

Abdominocentesis is a diagnostic procedure where a needle is inserted into the abdomen to collect fluid or gas, not a surgical suturing process.

Thus, gastropexy accurately describes the procedure concerning suturing related to the abdominal area.
