Purpose: The purpose of this study was to be of much really help to surgern to carry out laparoscopic surgery. We introduced Hand-Assisted Laparoscopic Surgery (HALS) about colorectal surgery that is helpful in complex laparoscopic surgery. Methods: A prospective study was performed in 13 patients who had undergone surgical intervention with Hand-Assisted Laparoscopic Surgery (HALS) for colorectal tumor between January, 2002 and March, 2003. We performed by using conventional laparoscopic surgical instrument except EndoGIA and Omniport^TM (Weck Closure Systems, Research Triangle Park NC) for hand port. Results: The average age of patients was 61.3⁑13.1 years. These patients had benign diseases of 2 case and malignant diseases of 11 case. The benign disease were villous adenoma in sigmoid colon and mucocele in appendix. The malignant disease were early colorectal cancer of 9 cases and advanced colorectal cancer of 2 cases. The operations introduced low ant. resection (LAR) in 5 cases, ant. resection (AR) in 6 cases and right hemicolectomy in 2 cases. The average operative time were 176.0⁑51.1 minutes in LAR, 147.5⁑35.0 minutes in AR and 190.0⁑7.0 minutes in right hemicolectomy. The average intraoperative blood loss were 278.0⁑14.9 ml in LAR, 385.0⁑21.3 ml in AR and 125.0⁑35.3 ml in right hemicolectomy. The average postoperative stay were 9 days in LAR , 10 days in AR and 9 days in right hemicolectomy. The average hand port incision lengh was 8.1⁑0.2 cm. None of the patients required conversion to open surgery as a result of an unmanageable air leak. Conclusion: HALS is not a alternative procedure but a specific procedure for complexed colorectal surgery not performing by pure laparoscopic colorectal surgery.
