Which term would indicate a surgical fixation using the correct suffix?

The term that indicates a surgical fixation is "pexy." This suffix is used to describe the procedure of surgically securing an organ or tissue in place. For example, a “gastropexy” refers to the surgical fixation of the stomach.

The other suffixes, while related to surgical procedures, indicate different actions. The suffix "-scopy" refers to the visual examination of an organ or body cavity using an instrument, such as in "endoscopy." The suffix "-rrhaphy" signifies surgical suturing or stitching, commonly seen in terms like "herniorrhaphy." Conversely, "-ectomy" indicates the surgical removal of a body part or organ, as in "appendectomy," which denotes the removal of the appendix. Thus, "pexy" is the correct suffix to denote fixation.
