Abstract
BACKGROUND/OBJECTIVES: An incisional hernia (IH) is a frequent postoperative complication after cytoreductive laparotomic surgery for advanced ovarian cancer (AOC). It occurs in 2-22% of patients in the first two years of follow-up, depending on the series. Although different risk factors have been described for various types of malignancies and surgeries, few studies have analyzed the risk factors for hernia development in ovarian cancer (OC). However, none have examined the role of enhanced recovery after surgery (ERAS) programs. METHODS: We performed a retrospective study that included patients with AOC and primary or interval debulking surgery through a median laparotomic approach. This study was conducted in Vall d'Hebron Hospital, Barcelona, Spain, between January 2015 and December 2022. Univariate and multivariate regression analyses were conducted. RESULTS: Of the 156 patients included, 30 (19.2%) presented with an IH. The patients with IHs were smokers in a higher proportion to non-smokers (53.9% vs. 16.1%, p = 0.003) and more frequently presented with wound dehiscence (34.4% vs. 15.0%, p = 0.026). Patients in whom negative pressure wound therapy was applied had a hernia less frequently than those who had not had it (12.5% vs. 26.7%, p = 0.043). Similarly, the incidence of hernia decreased when patients went through an ERAS protocol (10.1% vs. 28.8%, p = 0.008). In the multivariate analysis, smoking was the only independent risk factor (RR 10.84, CI 2.76-42.64), and applying an ERAS protocol was seen to be the sole protective factor (RR 0.22, CI 0.08-0.61) against the development of an IH. CONCLUSIONS: The implementation of ERAS is highly recommended due to its numerous benefits, most notably the reduction in hernia incidence. Additionally, the preoperative identification of current smokers provides an opportunity for smoking cessation and targeted respiratory prehabilitation, both of which further contribute to IH reduction.
