RESUMO
Background: Many abdominal-pelvic surgeries utilize incisions not along the linea alba, such as transverse, laparoscopic, ostomy reversal, or ostomy formation incisions. The prevalence of ventral incisional hernias (VIH) at these sites and the efficacy of prophylactic mesh in preventing VIH remains unclear. Methods: PubMed, Embase, Scopus, and Cochrane databases were systematically reviewed from inception to September 2022. We included published randomized controlled trials (RCTs) that compared prophylactic mesh reinforcement versus no mesh. The primary outcome was the incidence of VIH at postoperative follow-up equal to or greater than 24 months. Secondary outcomes included surgical site infection (SSI) and surgical site occurrence (SSO). Results: Of 3186 screened articles, only 3 RCTs with at least an 80% 2-year follow-up, encompassing a total of 901 patients, were included for analysis of non-midline VIH. Fifteen additional RCTs were included for analysis of secondary outcomes. The rate of parastomal hernias with prophylactic mesh was 21%, while it ranged from 44%-64% in the control group. The rate of incisional hernia after ostomy reversal with prophylactic mesh was 10%, and 16% in the control group. No clear evidence of a difference was found in rates of SSI or SSO between groups. Conclusion: There is limited evidence on the role of prophylactic mesh in preventing non-midline VIH. More studies at low risk for bias are needed to elucidate the balance of the long-term risks and benefits of prophylactic mesh for non-midline incisions.
RESUMO
Objective: We aimed to evaluate the prevalence of highly detailed ventral hernia repair (VHR) operative reports and associations between operative report detail and postoperative outcomes in a medico-legal dataset. Background: VHR are one of the most common surgical procedures performed in the United States. Previous work has shown that VHR operative reports are poorly detailed, however, the relationship between operative report detail and patient outcomes is unknown. Methods: This is a retrospective cross-sectional observational study. Operative reports describing VHR were obtained from a medical-legal database. Medical records were screened and data was extracted including clinical outcomes, such as surgical site infection (SSI), hernia recurrence, and reoperation and the presence of key details in each report. Highly detailed operative reports were defined as having 70% of recommended details. The primary outcome was the prevalence of highly detailed VHR operative reports. Results: A total of 1011 VHR operative reports dictated by 693 surgeons across 517 facilities in 50 states were included. Median duration of follow-up was 4.6 years after initial surgery. Only 35.7% of operative reports were highly detailed. More recent operative reports, cases with resident involvement, and contaminated procedures were more likely to be highly detailed (all P < 0.05). Compared to poorly detailed operative reports, cases with highly detailed reports had fewer SSIs (13.2% vs 7.5%, P = 0.006), hernia recurrence (65.8% vs 55.4%, P = 0.002), and reoperation (78.9% vs 62.6%, P = 0.001). Conclusions: In this medico-legal dataset, most VHR operative reports are poorly detailed while highly detailed operative reports were associated with lower rates of complications. Future studies should examine a nationally representative dataset to validate our findings.
