643 Background: Safety and validity of performing laparoscopic surgery after preoperative lavege using the self-expandable metallic stent (SEMS) for left-sided obstructive colorectal cancer were examined. We evaluated the short-term outcome of SEMS insertion compared with laparoscopic surgery without SEMS. Methods: Patients with left-sided colorectal cancer treated by either laparoscopic surgery with stent placement (n = 8) or laparoscopic surgery only (n = 42) in our hospital between April, 2012 and January, 2013 were registered. Short-term outcomes were compared with the two groups about patient characteristics (sex, age, American Society of Anesthesiologists Physical Status, body mass index, prior abdominal surgery), pathological data of patients (tumor location, size of tumor , tumor differentiation, number of harvested lymph nodes, pTNM classification, UICC pathological stage), and operative and post operative results (procedures, conversion, operative time, blood loss, morbidity, solid food intake, postoperative hospital stay, total hospital stay). Results: Except for tumor size in the patient characteristic parameters, there were no statistically significant difference between the two groups. Conversion rate to laparotomy was higher in the stent group (2 versus 1, p = 0.013). There was no difference in operation time, blood loss and postoperative complications between the two groups. Conclusions: Although the long-term oncological result requires further investigation, laparoscopic surgery after self-expandable metallic stent is a safe and feasible treatment as a “brige to surgery” for left-sided obstructive colorectal cancer.
