Background:
The use of prostheses in inguinal hernia repair reduces the incidence of recurrence. Quality of life and pain after hernia repair are largely correlated with the technique and type of prosthesis.
Aims Of Study:
To evaluate the 2-year incidence of recurrence and pain for two types of hernioplasty, Lichtenstein repair and laparoscopy (totally extraperitoneal approach or TEP), and two types of mesh, polypropylene mesh and beta-D: -glucan-coated mesh (Glucamesh).
Patients:
A total of 410 consecutive patients of mean age 54 years (18-84) underwent repair of inguinal hernias, 96 (23%) of which were bilateral and 56 (13%) recurrent. A total of 273 (66.5%) patients underwent Lichtenstein repair: 215 (78.7%) with polypropylene mesh, 58 (21.3%) with Glucamesh; 137 patients underwent laparoscopy: 80 (58.4%) with polypropylene mesh, 57 (41.6%) with Glucamesh. In each group, the populations were comparable and the techniques utilized were identical.
Methods:
The patients were followed-up for at least 2 years, after which the incidence of recurrence was determined, and chronic pain was assessed by means of a visual analog scale and a validated questionnaire.
Results:
A total of 349 patients (85.1%) were reassessed, 117 of whom had undergone laparoscopy and 232 Lichtenstein repair. There were ten recurrences (2.8%), and incidence which was independent of the technique (laparoscopy 1.7% vs. Lichtenstein 3.4%) (ns) and the type of prosthesis (Glucamesh 1.9% vs. polypropylene 2.4%) (ns). Chronic pain was noted in 69 patients (19.7%) and severe pain in 11 (3.1%). The incidence of chronic pain was the same for the two techniques: laparoscopy 17.9% vs. Lichtenstein 20.7% (ns). The same was true for severe pain: laparoscopy 3.4% vs Lichtenstein 3% (ns). The incidence of chronic pain was closely correlated with the type of prosthesis utilized: Glucamesh 4.8% vs. polypropylene 26.5% (P = 0.02), irrespective of the technique. The same was true for severe pain (0.9 vs. 4%) (P = 0.02).
Conclusion:
The utilization of beta-D: -glucan-coated mesh did not involve more recurrence and was accompanied by a significant decrease in chronic pain at 2 years, independent of the technique. After 2 years, the results of hernia repair show that the choice of prosthesis was more determinant than choice of technique.
