Abstract Aim This study has two aims: to evaluate long‐term chronic pain and complications after circular incision transabdominal preperitoneal inguinal hernia repair (C‐TAPP) and compare outcomes of unilateral and bilateral inguinal hernia cases. Methods A postoperative patient questionnaire was used to evaluate pain and complications in 1546 patients who underwent C‐TAPP for simple inguinal hernia. Questions concerned satisfaction with surgery, pain at rest, pain at movement, mesh discomfort on a 10‐point scale, and complications, such as recurrence. Patients were classified into unilateral (U Group) and bilateral (B Group) groups, and propensity score matching was performed to compare long‐term chronic pain and complications. Results The questionnaire return rates were 77.5% (1034 cases) and 79.9% (135 cases) in unilateral and bilateral cases. The frequency of moderate‐to‐severe (≥4 points) pain at rest, pain at movement, and mesh discomfort were 3.2%, 3.6%, and 4.5%, respectively. After propensity score matching, no significant differences in pain at rest (P = .726), at movement (P = .712), or mesh discomfort (P = .981) were detected between the U and B groups. Postoperative complications occurred in 2.1% of all patients, and the recurrence rate was 0.3%. In the post‐match comparison, no differences in complications with Clavian‐Dindo classification ≥III (U Group 0.7%, B Group 2.1%, P = .622) were detected. Conclusion C‐TAPP, which focuses on the layered structure, showed acceptable results for long‐term chronic pain. Bilateral cases did not have worse pain or complications compared to unilateral cases. |
