Objectives:
Although laparoscopic inguinal hernia repair (LIHR) has been widely accepted for treating inguinal hernia, the procedure remains very technical and challenging. The present study aimed to assess the effect of LIHR in relation to operation time, intraoperative hemorrhage and postoperative hospitalization.
Methods:
A total of 503 patients with inguinal hernia admitted at the Wuxi Rehabilitation Hospital between June 2019 and July 2021 were included in this retrospective cohort study. Binary logistic and linear regressions were used for categorical and continuous outcomes, respectively. The learning curve was drawn by cumulative sum analysis.
Results:
Multivariate logistic regression analysis identified LIHR as an independent factor associated with prolonging operation time (odd ratio [OR] = 1.750, 95% confidence interval [CI]: 1.215-2.520, p = 0.003) and decreasing intraoperative hemorrhage levels (OR = 0.079, 95 CI: 0.044-0.142, p < 0.001). Multivariate linear regression identified LIHR (Coefficient = -0.702, 95% CI: [-1.050] to [-0.354], p < 0.001) as an independent factor for shortening postoperative hospitalization time. After learning curve, LIHR (OR = 1.409, 95% CI: 0.948 to 2.094, p = 0.090) no longer resulted as a risk factor prolonging operation time.
Conclusions:
LIHR is an important independent predictive factor for decreasing intraoperative hemorrhage levels and shortening postoperative hospitalization time. Additionally, LIHR does not prolong operation time after the learning curve.
