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.
There are 200 patients undergoing open inguinal hernia repair (IHR) with tension-free technique (mesh repair).We found no differences in analgesic efficacy (NRS value ≥4 in the first 96 hours: 26% in group K vs 32% in group T, P = .43); the proportion of patients with NRS ≥4 was similar in both groups, and the time trajectories were not significantly different (P for interaction = .24). Side effects were higher (12% vs 6%) in the tramadol group, although not significantly (P = .14), with a case of bleeding in the ketorolac group and higher incidence of constipation in tramadol group. One patient in each group developed chronic pain.
