The impact of laparoscopic versus open inguinal hernia repair for inguinal hernia treatment: A retrospective cohort study

Abstract

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.

Laparoscopic versus open inguinal hernia repair in aging patients: A propensity score matching-based retrospective study

“…Previous studies have shown that surgeons need to go through a special learning curve from basic operations to pro ciency in mastering LIHR techniques [30] . Other medical centers have reported a range of 50 to 250 cases [31] , while our center recently reported 54 cases as well [9] . All patients this study were completed by the same group of senior and professional surgeons.…”

“…Laparoscopic inguinal hernia repair (LIHR) and open inguinal hernia repair (OIHR) procedures are often compared during the 20 years [4,[6][7][8][9] . Importantly, with the advantages of minimally invasive technology, such as reduced wound complications, less recurrence rate, and faster recovery, which is highly favored by not only surgeons, but also patients [10] .…”

Laparoscopic transabdominal preperitoneal herniorrhaphy performed using an articulating laparoscopic instrument is feasible and more efficient

“…Laparoscopic hernia surgery shows various advantages over open inguinal hernia surgery (7)(8)(9), including lower operation times, early recovery, and fewer complications (10). However, the choice between TEP and TAPP remains unclear (11)(12)(13).…”

“… 30 Other medical centers have reported a range of 50 to 250 cases, 31 while our center recently reported 54 cases as well. 9 All patients in this study were completed by the same group of senior and professional surgeons. Perhaps, the LIHR approach could be performed easier by exerted surgeons after overcoming the laparoscopic technical learning curve, thereby significantly shortening the operative time, which in this study was similar to that of the OIHR group.…”
