Resultados da herniorrafia inguinal bilateral simultânea pela técnica de Lichtenstein

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

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.

Assessment of postoperative risk of complications on inguinal hernioplasty and its relation to risk factors

INTRODUCTION Abdominal wall hernias are a highly prevalent pathology, considering that 55 percent of the world population is affected by this disease at some point in their lives. As a large part of these patients present comorbidities, it is important to correlate the incidence of complications with the presence of previous pathologies. OBJECTIVES To evaluate whether the presence of comorbidities in patients submitted to inguinal hernioplasty increases the risk of acute and chronic complications in the postoperative period, as well as to explain which of these prior diseases present a greater association with the incidence of complications. METHODS This is a cross-sectional descriptive study carried out through the retrospective analysis of 313 medical records of patients submitted to open inguinal hernioplasty surgery between March and June 2017 at the General Surgery Service of the Cruz Vermelha Hospital - Paraná Branch, located in the City of Curitiba, state of Paraná, Brasil. RESULTS Of the 313 cases studied, the most prevalent comorbidities were: 107 patients with hypertension (34.19%), 52 smokers (16.61%), 30 cases with diabetes (9.58%), 14 with hypothyroidism (4,47%) and 10 with COPD (3.19%). Regarding the total of the sample evaluated, 130 patients (41.53%) did not present any comorbidity. When evaluating the complications, there were 49 cases (15.65%) of complications in the early postoperative period and 9 cases (2.88%) of chronic complications. The comorbidities that presented significant statistical influence (p <0.05) on the incidence of acute complications were hypertension (p = 0.02927) and smoking (p = 0.03196). CONCLUSION It is important to note the presence of acute postoperative complications of inguinal hernioplasty in patients who have hypertension or smoke, high prevalence diseases.
