Background: Even though the introduction of endoscopic surgical techniques to inguinal hernia therapy dates back 10 years, only a few data exist concerning the problem of development of a recurrence after endoscopic repair. Similarly there are only anecdotal reports on the feasibility of an endoscopic reintervention for this situation. For the first time we are able to present data of a prospective study on both issues.
Study Design: We analyzed the data of a prospectively documented series of 46 transperitoneal hernia repair reinterventions after endoscopic hernia repair. In 33 patients from our own clinic we evaluated the cause of recurrence after transperitoneal hernia repair. Together with these and 13 more patients sent to us from external clinics we examined the efficiency of an endoscopic reoperation.
Results: When implanting a 13 × 8-cm mesh with an incision (phase I) we found the main cause of recurrence to be that the mesh was too small (47.4%) and the region of the mesh incision was insufficient (42.1%). After a change to a 15 × 10-cm implant without incision (phase II) the main cause of recurrence was found to be a mesh dislocation (38.9%) and the rate of recurrence dropped from 2.8% (phase I) to 0.36% (phase II). The transperitoneal reoperation lasted for a median of 75 minutes (range 45 to 170 minutes) for the medial recurrence and a median of 110 minutes (range 65 to 190 minutes) for the lateral recurrence (p = 0.009). The total rate of complications was 10.9%, and the rate of re-recurrence was 0% after a median followup of 26 months (range 2 to 72 months).
Conclusions: To avoid hernia recurrence after transperitoneal hernia repair operations a sufficiently large mesh (at least 15 × 10 cm) has to be implanted, preferably without an incision, after an extensive parietalization. The endoscopic reoperation for recurrence can be done only in a transperitoneal way and is effective with comparably low complication rates. The procedure is significantly easier for a medial recurrence compared with a lateral recurrence. This method of reoperation should be reserved for endoscopically experienced surgeons.
