 note = {Introduction: The employment of laparoscopic resection for the treatment of colorectal cancer has been
expanding rapidly. However, its indication is still on debate. We have been actively employing laparoscope-assisted colectomy （LAC） for patients with early colorectal cancer. Here we retrospectively review the 71 cases of early colorectal 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 was employed as a definitive non-endoscopic treatment in 44 cases. Mean operative time was 163 min, and mean blood loss was 57 ml. Complications were encountered in 8 cases（ 11.3%）. Advanced lesions invading to the muscularis propria or the serosa were more included in the group initially treated with LAC alone（ p=0.04）. The reasons for additional LAC were the depth of submucosal invasion >1000 μm in 15 cases and lymphatic or microvascular invasion in 5 cases. 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 both
radicality and less invasiveness. Cooperation between endoscopists and laparoscopic surgeons is important to apply LAC appropriately for colorectal cancer., 弘前医学. 62, 2011, p.173-179},
