Introduction: The employment of laparoscopic resection for the treatment of colorectal cancer has beenexpanding rapidly. However, its indication is still on debate. We have been actively employing laparoscope-assistedcolectomy （LAC） for patients with early colorectal cancer. Here we retrospectively review the 71 cases of earlycolorectal cancer treated with LAC and analyzed the initial institutional surgical outcome.Results: LAC was indicated as an additional surgical resection after endoscopic treatment in 27 cases, while it wasemployed as a definitive non-endoscopic treatment in 44 cases. Mean operative time was 163 min, and mean blood losswas 57 ml. Complications were encountered in 8 cases（ 11.3%）. Advanced lesions invading to the muscularis propriaor the serosa were more included in the group initially treated with LAC alone（ p=0.04）. The reasons for additionalLAC were the depth of submucosal invasion >1000 μm in 15 cases and lymphatic or microvascular invasion in 5cases. Lymph node metastases were detected pathologically in 9 patients, in which one suffered relapse after surgery.Conclusion: Implementation of LAC for early colorectal cancer seems an acceptable strategy in terms of bothradicality and less invasiveness. Cooperation between endoscopists and laparoscopic surgeons is important to applyLAC appropriately for colorectal cancer.
