Which suffix would indicate a surgical procedure involving an opening?

The suffix that indicates a surgical procedure involving an opening is “-ostomy.” This term specifically refers to the creation of an artificial opening or stoma in an organ or structure. For instance, in a colostomy, a portion of the colon is brought through the abdominal wall to divert waste, creating an opening.

In contrast, the suffix “-otomy” refers to the act of cutting or incision, often to allow for access or examination of an internal structure rather than creating a permanent opening. Terms like “laparotomy” are examples, where a surgical incision is made into the abdominal cavity.

The suffix “-osis” signifies a condition, often implying a pathological state, while “-otic” pertains to the nature or condition of a disease or process. Neither of these suffixes is relevant to indicating a surgical opening.

Thus, “-ostomy” is the precise term used in medical terminology for procedures that involve creating an opening, making it the correct choice.
