Laparoscopic Colorectal Surgery Modifies Risk Factors for Postoperative Morbidity

PURPOSE: METHODS: RESULTS:The overall morbidity rate was 27.1 percent, with the rate in the laparoscopic group (18.7 percent) being less than that in the open group (31.5 percent; P = 0.003). Patients who underwent laparoscopic resection had a faster recovery of bowel function (P = 0.0001) and a shorter length of stay (P = 0.0001). In the whole cohort of patients, multivariate analysis identified open surgery (P = 0.003), duration of surgery (P = 0.01), and homologous blood transfusion (P = 0.01) as risk factors for postoperative morbidity. In the open group, blood loss (P = 0.01), homologous blood transfusion (P = 0.01), duration of surgery (P = 0.009), weight loss (P = 0.06), and age (P = 0.08) were related to postoperative morbidity. In the laparoscopic group the only risk factor identified was duration of surgery (P = 0.005). CONCLUSION:
