Prognosis analysis
death
Patients underwent emergent laparotomy under general anesthesia. The periods between definite diagnosis (by contrast CT scan) and surgery were measured. Operative factors included combined colon resection, end-enterostomy or reanastomosis, length of functional residual small intestine (length between the Treitz ligament and the end-enterostomy or ileocecal area), and blood transfusion. Both postoperative anticoagulant agents and postoperative antiplatelet agents were recorded. Postoperative mortality was defined as death after intestinal resection. The periods between intestinal resection and death were measured. The 30-day mortality was analyzed for short-term results. The prognosis was revealed by the survival curve.
