Prevalence and Risk Factors of Low Anterior Resection Syndrome in Epithelial Ovarian Cancer Surgery

Abstract

Background In this study, we aimed to determine the prevalence and risk factors of low anterior resection syndrome (LARS) in epithelial ovarian cancer (EOC) surgery. Methodology A descriptive cross-sectional study was conducted at the Gynecologic Oncology Section of the Department of Surgical Oncology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Lahore, Pakistan. Using non-probability consecutive sampling technique, all patients who underwent cytoreductive surgery involving low anterior resection for EOC between January 2016 and January 2021 were included. Patients were assessed for LARS symptoms using the LARS score, along with its risk factors. Descriptive statistics, that is, continuous variables were expressed as the median and interquartile range, while categorical variables were expressed as frequencies and percentages. The LARS score was categorized according to a two-tier model with "no or minor LARS" and "major LARS." Univariate analyses were performed by the chi-square tests providing odds ratios and 95% confidence intervals to identify risk factors for major LARS. Results Overall, 95% of cases had LARS scores that fell in "no or minor LARS," while only 5% of cases had "major LARS." Univariate analyses relieved no statistically significant association between the occurrence of major LARS and any of the risk factors. Conclusions The prevalence of LARS was 5%, and no risk factors were associated with major LARS in our study population.
