Introduction:
The present study was performed to compare postoperative pain following transinguinal preperitoneal repair (TIPP) and transabdominal preperitoneal repair (TAPP) performed by a single surgeon with adequate experience in each procedure.
Material And Methods:
Adult patients who underwent herniorrhaphy for elective unilateral primary inguinal hernia repair from April 2013 to October 2019 were identified. After propensity score matching, a numeric rating scale was used to compare postoperative pain scores at 1 day, 1 week, and 1 month between patients who underwent TAPP and TIPP.
Results:
Among 784 patients who underwent herniorrhaphy during the study period, 354 were analyzed by propensity score matching (TAPP, n = 177; TIPP, n = 177). Postoperative pain during normal activity was significantly lower in the TAPP group than in the TIPP group on day 1 (2.75 ± 1.67 versus 3.59 ± 1.86, p < 0.01), at 1 week (0.98 ± 1.11 versus 1.75 ± 1.51, p < 0.01), and at 1 month (0.11 ± 0.48 versus 0.29 ± 0.78, p = 0.01). There was no difference in pain at rest on day 1 and at one week, although TAPP was associated with significantly less pain at rest at one month than was TIPP (0.01 ± 0.08 versus 0.1 ± 0.49, p = 0.02).
Conclusion:
TAPP is preferable to TIPP in patients undergoing elective unilateral primary inguinal hernia repair in terms of reducing short-term pain.
