Previous research has shown that the repair of a recurrent inguinal hernia is subject to a greater risk of additional recurrence. Further, bilateral inguinal hernia is subject to a greater recurrence risk than unilateral inguinal hernia. These increased risks may be due to certain anatomical difficulties that complicate the surgical approach in these types of patients. Some clinicians have suggested that laparoscopic approaches are better suited to recurrent and bilateral hernias, and in we delineate separate comparisons for primary, bilateral, and recurrent hernia.
Data were collected retrospectively from patient files and were analyzed for 405 male and female patients with 483 primary inguinal hernias. All patients included had undergone surgical repair for inguinal hernia by the laparoscopic transabdominal preperitoneal (TAPP) approach using Parietex ProGrip meshes performed in the same clinical center in Germany. Pre-, peri-, and postoperative data were collected and a follow-up after 12 and 24 months was performed prospectively. Complications, pain scored on a 0 to 10 NRS scale, patient satisfaction, and hernia recurrence were assessed.Two patients had to be reoperated due to a hematoma in inguinal canal. At mean follow-up at 22.8 months, there were only eight reports of hernia recurrence: 1.9% of the hernias. Most patients (94.9%) were satisfied or very satisfied with their hernia repair with only 1.2% reporting severe pain (NRS score 7 to 10) and 3.6% reported mild pain.
