Sigmoid volvulus: outcomes of treatment and predictors of morbidity and mortality.

Purpose: To analyze the treatment outcomes for sigmoid volvulus (SV) and identify risk factors of complications and mortality.

Methods: Observational study of all consecutive adult patients diagnosed with SV who were admitted from January 2000 to December 2020 in a tertiary university institution for conservative management, urgent or elective surgery. Primary outcomes were 30-day postoperative morbidity, mortality and 2-year overall survival (OS), including analysis of risk factors for postoperative morbidity or mortality and prognostic factors for 2-year OS.
