Postoperative outcomes using Lichtenstein open hernioplasty versus Nyhus preperitoneal hernioplasty in inguinal hernia: A comparative analysis with 1‐year follow‐up

Abstract

Abstract Background and Aim Inguinal hernia is the most common defect of the abdominal wall in 75% and their treatment consists of surgical repair. The technique of choice is laparoscopic because of its overall benefits. However, when this is not available, open approaches may be a viable option. Currently, the most commonly used open techniques are Lichtenstein and Nyhus. However, there are few medium‐ or long‐term studies that have compared outcomes between these two techniques. Methods This is a retrospective comparative study that included patients undergoing open inguinal hernia correction with mesh, using Lichtenstein open hernioplasty versus Nyhus preperitoneal hernioplasty, in two tertiary referral centers in Bogota, Colombia, during a period of 2 years. A bivariate analysis was performed to compare groups, according to the complications presented between the two techniques. Results A total of 193 patients were included, of whom 53.36% were men and 112 (58.03%) were approached with the Nyhus technique versus 81 patients with the Lichtenstein technique. Nonabsorbable suture fixation was performed in 100% of patients. Among the main complications, seroma (5.18%), pain (4.14%), bleeding (2.07%), recurrence (10.88%), and reoperation (0.51%) were observed, of which only recurrence showed a statistically significant difference, which is lower in the Nyhus approach (3.57% vs. 20.67%; p < 0.001). No patients died. Conclusions Both Nyhus and Lichtenstein hernioplasty techniques were shown to cause a low incidence of postoperative complications, with significantly lower recurrence using the Nyhus technique up to 1 year postoperatively.
