Diaz-Plasencia and Rebaza-Iparraguirre developed a score for grading the severity of colonic gangrene consequent to volvulus. It can help identify patients at high risk for mortality who may benefit from more aggressive therapy. In Spanish this was called the Puntaje de Severidad de Gangrena por volvulo de Colon (PSGC); in English the Score of the Severity of Gangrenous Colon by volvulus (SSGC). The authors are from Hospital Belen de Trujillo, Peru.
