Prospective randomized trial comparing Shouldice and Bassini-Kirschner operation technique in primary inguinal hernia repair.

The authors conducted a prospective randomized trial to compare the Shouldice and the Bassini-Kirschner technique between April, 1994 and December, 1995. During this period 129 adult patients, mean age 54 (17-87) years underwent operation on primary inguinal hernias in their department. 63 Shouldice and 66 Bassini-Kirschner operations were performed by 17 surgeons. The duration of surgery, the technique of anesthesia, the perioperative complications, the duration of postoperative care, then one year after the operation the recurrence rate and the patient's subjective complains were investigated. 85 patients of 129 were examined one year after the operation in spite of that all the patients were invited for control. Both operations gave almost the same results in the perioperative period and nearly identical recurrence rate (4.44% in Shouldice and 5.0% in Bassini-Kirschner group). The patient's subjective complains were also very similar one year after the operation. The authors could not find significant difference in the results of the two types of surgery although they were well experienced with the Bassini-Kirschner operation and just starting to practice the Shouldice procedure. These facts suggest that having more experience with the Shouldice operation makes available the extreme low recurrence rate published by several authors.
