Surgical treatment of recurrent groin hernia

Recurrent groin hernia is not uncommon in Taiwan. Subsequent surgical repairs are difficult, due to cicartrization and deterioration of the inguinal floor. In this report, the intermediate and long-term outcomes of 212 patients with recurrent groin hernias who underwent surgical repair within a 10-year period were analyzed in order to assess the effectiveness of two modified repair techniques. Patients with unilateral first-time recurrent hernia (UR; n = 87) were treated by a modified Shouldice technique using an inguinal approach. Those with bilateral or multiple recurrences (MRs; n = 125) were treated with giant prosthetic reinforcement of the visceral sac (GPRVS, Stoppa operation) using a midline preperitoneal approach. Complete exploration of the groin floor on the side of recurrence revealed a high rate of direct space defects (UR, 41.5%; MR, 65%) and multiple posterior wall defects (UR, 29.9%; MR, 30%). In the UR group, a 4 x 10-cm preperitoneal prosthetic mesh was incorporated to reinforce the repair. For MR patients, I reduced the transverse dimension of the mesh prosthesis by 2 cm compared with the original Stoppa protocol; to reduce crinkling, the average dimensions were 23 x 14 cm. Complications in the UR group included testicular atrophy (3 patients) and femoral vein thrombosis (1). Complications in the MR group were transient scrotal fluid accumulation (9 patients), fatal perioperative acute myocardial infarction (1), and failure of the peritoneum to grow over the mesh (1). The average hospital stay was 3 days in the UR group and 6 days in the MR group. The long-term follow-up (1-9 years) revealed a 5.7% re-recurrence rate with an 86.2% follow-up rate in the UR group, and a 1.9% re-recurrence rate with an 86.6% follow-up rate in the UR group. I conclude that GPRVS is an excellent treatment for URs, but the transverse dimension of the prosthetic mesh should be reduced for Taiwanese subjects. However, for first-time MRs, a modified Shouldice technique with incorporation of a preperitoneal prosthetic mesh is still recommended. The surgical dissection is less extensive and the hospital stay is shorter, while the re-recurrence rate is acceptably low.
