Meanings of type of surgical procedure in English

Thirty-seven non-hemophiliac patients served as matched pairs who matched for age, gender, accompanying diseases, and the type of surgical procedure.

There were no differences between the two groups with respect to age, gender, weight, duration, or type of surgical procedure or intraoperative opioid requirements.

From PREZIES data, we selected data from 2009 to 2014 relating to 13 types of surgical procedures.
