For a study, researchers aimed to identify prognosis factors for favorable functional recovery after CES. About 140 patients were taken between January 2010 and 2019. Univariate and multivariate cox proportional hazard regression models were done. Patients were young with a median age of 46.8 years (range 18–86 years). At presentation, 60% were affected by a motor deficit, 42.8% a sensitive deficit, 70% urinary dysfunctions, and 44% bowel dysfunctions. The mean follow-up was 15.5 months. Bilateral motor deficit (P=0.017) and an initial deficit severity of 0 to 2 (P=0.001) represented prognosis factors of poor motor recovery. Initial anal incontinence (P=0.007) was related to poor bowel recovery. Only 32.8% of the patients went back to work. Initial motor deficit (P=0.015), motor sequelae (P=0.001), sphincter dysfunctions sequelae (P=0.02), and long LOS (P=0.02) were poor return-to-work prognosis factors. Time to surgery within an early timing less than 24 or 48 hours or later did not represent a prognosis factor of recovery in CES. Incomplete versus complete CES did not show better recovery. Early or later surgical cauda equina decompression did not show to represent a prognosis factor for functional recovery.
