Purpose
The aim of this study was to evaluate the outcome, with a special reference to recurrence and postoperative chronic pain, of the modified Kugel herniorrhaphy (MKH) using standardized dissection of the preperitoneal space.
Patients and methods
Operative results were examined based on medical records and questionnaire surveys in 340 consecutive cases of MKH performed at a single institution. The operation was performed with an original 3-stage dissection of the preperitoneal space only via the internal inguinal ring.
Results
The mean follow-up period was 50.5 ± 24.3 months. The mean operating time was 42.2 ± 13.1 min, and by Nyhus classification, significant difference was observed between types IIIA and IIIB (39.5 ± 10.8 vs. 45.6 ± 15.6 min, P = 0.0279). Eight surgeons performed 10 or more operations, and no significant difference was found in their operating time. Thirty-one patients used additional analgesics postoperatively (9.1 %) and the length of postoperative stay was 1.2 ± 0.7 days. Seven patients (2.1 %) developed complications related to the hernia operation, but none of them required re-operation. The period required to return to normal daily activities was 3 ± 3.2 days. Questionnaire forms were returned from 77.7 % of all the patients, in which 12 patients reported chronic pain (4.7 %). Visual analog scale for patients with chronic pain scored 3.8 ± 2.4, with no patient indicating restrictions on daily life. Recurrence was observed in only one case (0.3 %).
Conclusion
MKH using standardized dissection of the preperitoneal space is a highly reproducible procedure with acceptable rate of postoperative chronic pain and recurrence.
