Purpose: There are various opinions about the postoperative complications of the two methods for laparoscopic inguinal hernia surgery; totally extraperitoneal repair (TEP) and transabdominal preperitoneal repair (TAPP). The aim of this study was to compare the postoperative course after TAPP and TEP, focusing on immediate postoperative pain, incidence of postoperative urinary retention (POUR), and chronic pain. Methods: This study retrospectively analyzed a consecutive series of 344 inguinal hernia patients who were treated with laparoscopic surgery between November 2016 and December 2019 at a single tertiary referral center. Results: Patient demographics did not differ significantly between the groups. The operation time was significantly shorter in the TEP group than in the TAPP group (43.1 ± 14.9 minutes vs. 63.5 ± 16.5 minutes, p < 0.001). The postoperative pain scores were significantly lower in the TEP group than in the TAPP group immediately (3.6 ± 1.3 vs. 4.4 ± 1.1, p < 0.001) and 6 hours (1.5 ± 1.4 vs. 2.3 ± 1.8, p < 0.001) after the operation. The other complications did not differ significantly between the groups. Age was a significant risk factor for POUR (odds ratio [OR], 1.083; 95% confidence interval [CI], 1.018–1.151; p = 0.011), and history of benign prostate hyperplasia (BPH) was a significant risk factor for chronic pain (OR, 5.363; 95% CI, 1.028–27.962; p = 0.046). Conclusion: TEP and TAPP seem to be safe and effective for laparoscopic inguinal hernia repair and have similar postoperative outcomes. Age was a significant risk factor for POUR, and BPH history was a significant risk factor for chronic pain. KCI Citation Count: 0
