Analysis of risk factors associated bowel resection in patients with incarcerated groin hernia

Incarcerated groin hernia (IGH) is a common surgical emergency. However, there are few accurate and applicable predictors for differentiating patients with strangulated groin hernia from those with IGH. In this study, we aimed to identify the independent risk factors for bowel resection in patients with IGH.

We retrospectively collected 323 patients who underwent emergency hernia repair surgery for IGH between January 2010 and October 2019. The patients were categorized into those who received bowel resection and those who did not require bowel resection. The receiver-operating characteristic curve was used to identify the best cutoff values for continuous variables. Following this, univariate and multivariate analyses were performed to identify potential risk factors for bowel resection in these patients.

Univariate analysis identified 6 variables that were significantly associated with bowel resection among patients with IGH. On multivariate analysis, neutrophil-to-lymphocyte ratio (NLR) (odds ratio [OR] = 3.362, 95% confidence interval [CI] 1.705-6.628, P = .000) and bowel obstruction (OR = 3.191, 95% CI 1.873-5.437, P = 0.000) were identified as independent risk factors for bowel resection among patients with IGH.

In this study, an elevated NLR and those with bowel obstruction are associated with an increased risk of bowel resection among patients with IGH. Based on our findings, surgeons should prioritize prompt emergency surgical repair for patients who present with elevated NLR and bowel obstruction concurrent with IGH.
