Easterday A, et al. - Researchers sought to develop a model that may allow predicting the need for emergent surgery and mortality after resection for sigmoid volvulus. Searching the NSQIP database from 2012 to 2016, they included 2,086 patients who underwent segmental resection for sigmoid volvulus. Emergency surgery was observed in correlation to the following factors: female gender, relative hematocrit elevation, relative leukocytosis, acute kidney injury, preoperative sepsis, prior functional independence, and bleeding disorders. In nonemergent setting, they observed more frequent undertaking of laparoscopic resection and mechanical bowel preparation. Postoperative superficial surgical site infection, pneumonia, cardiac arrest, septic shock, myocardial infarction, and receipt of perioperative transfusion were more frequent among patients having emergent resection. Increased age, systemic sepsis, and emergent surgery were the predictive factors of postoperative mortality. The protective effect was observed of independence before illness, higher albumin levels, and lower BMI.
