Abstract
BACKGROUND Sex is emerging as an important clinical variable associated with surgical outcomes and decision making. However, its relevance in regard to baseline and treatment differences in primary and incisional ventral hernia repair remains unclear. STUDY DESIGN This is a retrospective cohort study using the Abdominal Core Health Quality Collaborative database to identify elective umbilical, epigastric, or incisional hernia repairs. Propensity matching was performed to investigate confounder-adjusted treatment differences between men and women. Treatments of interest included surgical approach (minimally invasive or open), mesh use, mesh type, mesh position, anesthesia type, myofascial release, fascial closure, and fixation use. RESULTS A total of 8,489 umbilical, 1,801 epigastric, and 16,626 incisional hernia repairs were identified. Women undergoing primary ventral hernia repair were younger (umbilical 46.4 vs 54 years, epigastric 48.7 vs 52.7 years), with lower BMI (umbilical 30.4 vs 31.5, epigastric 29.2 vs 31.1), and less likely diabetic (umbilical 9.9% vs 11.4%, epigastric 6.8% vs 8.8%). Women undergoing incisional hernia repair were also younger (mean 57.5 vs 59.1 years), but with higher BMI (33.1 vs 31.5), and more likely diabetic (21.4% vs 19.1%). Propensity-matched analysis included 3,644 umbilical, 1,232 epigastric, and 12,480 incisional hernias. Women with incisional hernia were less likely to undergo an open repair (60.2% vs 63.4%, p < 0.001) and have mesh used (93.8% vs 94.8%, p = 0.02). In umbilical and incisional hernia repairs, women had higher rates of intraperitoneal mesh placement and men had higher rates of preperitoneal and retro-muscular mesh placement. CONCLUSIONS Small but statistically significant treatment differences in operative approach, mesh use, and mesh position exist between men and women undergoing ventral hernia repair. It remains unknown whether these treatment differences result in differing clinical outcomes.

Short-term complications after minimally invasive retromuscular ventral hernia repair: no need for preoperative weight loss or smoking cessation? Hernia 2022; 26:1315-1323. [PMID: 35995885 DOI: 10.1007/s10029-022-02663-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Accepted: 07/30/2022] [Indexed: 11/04/2022]
Abstract
PURPOSE Obesity and smoking are associated with postoperative wound complications following open hernia repair. However, with the advancements in minimally invasive surgical techniques, we hypothesized that obese and/or smoking patients undergoing minimally invasive repairs were not subjected to an increased risk of postoperative surgical complications. As opposed to nonobese and/or nonsmoking patients. METHODS This was a retrospective cohort study including patients undergoing minimally invasive retromuscular repair at a single university hospital. Patients were divided into two groups according to exposure; obese vs. nonobese and smoking vs. nonsmoking. One month postoperatively, all patients underwent clinical follow-up. The main outcome was surgical site occurrence (SSO). RESULTS A total of 94 patients were included, undergoing both laparoscopic (n = 32) and robotic (n = 62) retromuscular repair. Of these, 7.7% of the obese patients had SSO when compared with 19.1% of the nonobese patients. A total of 17.2% of the nonsmokers had SSO compared with 13.3% of the active smokers. Of the nonsmokers, 12.5% developed seroma and 6.2% hematoma postoperatively, the corresponding numbers were 13.3% and 0% among the active smokers. After multivariable analysis, there was no significant risk factors for developing postoperative SSO. CONCLUSION There was no association between obesity or smoking and surgical complication in patients undergoing minimally invasive retromuscular repair. If the results of the current study are confirmed, patients who are unable to obtain weight loss or smoking cessation may be offered minimally invasive retromuscular ventral hernia repair without inducing an increased risk of short-term complications.

Abstract
BACKGROUND A substantial knowledge gap exists in understanding sex as a biological variable for abdominal wall hernia repair, which also extends to hernia repair practices in females of childbearing age. We sought to determine the incidence of mesh repairs in females of childbearing age and to characterize factors associated with mesh use. METHODS Using a statewide hernia-specific data registry, we conducted a retrospective study identifying females of childbearing age, defined as 18-44 per CDC guidelines, who underwent clean ventral hernia repair between January 2020 and Dec 2021. The primary outcome was mesh use. Multivariable logistic regression was used to examine factors associated with mesh use. To further delineate whether childbearing status may affect decision to use mesh, we also examined mesh practice stratified by age, comparing women 18 to 44 to those 45 and older. RESULTS Eight hundred and thirty-six females of childbearing age underwent ventral hernia repair with a mean age of 34.8 (6.2) years. Mesh was used in 547 (65.4%) patients. Mesh use was significantly associated with minimally invasive approach [aOR 29.46 (95% CI 16.30-53.25)], greater hernia width [aOR 1.50 (95% CI 1.20-1.88)], and greater BMI [aOR 1.05 (95% CI 1.03-1.08)]. Age was not significantly associated with mesh use [aOR 1.02 (95% CI 0.99-1.05)]. Compared to 1,461 female patients older than 44 years old, there was no significant association between childbearing age and mesh use [aOR 0.77 (95% CI 0.57-1.04)]. CONCLUSIONS Most females of childbearing age had mesh placed during ventral and incisional hernia repair, which was largely associated with hernia size, BMI, and a minimally invasive surgical approach. Neither chronologic patient age nor being of childbearing age were associated with mesh use. Insofar as existing evidence suggests that childbearing status is an important factor in deciding whether to use mesh, these findings suggest that real-world practice may not reflect that evidence.
