BACKGROUND: Hand-assisted laparoscopic surgery has been introduced as an alternative to conventional laparoscopic surgery. This study compared the efficacies and short-term clinical outcomes between hand-assisted laparoscopic anterior resection (HAL-AR) and conventional laparoscopic anterior resection (CL-AR) for treating left-sided colon cancer. MATERIALS AND METHODS: We retrospectively analyzed 248 patients who underwent anterior resection for colon cancer (118 HAL-AR and 128 CL-AR) between May 2000 and December 2006. The collected data included the perioperative and short-term oncologic outcomes. RESULTS: There were no significant differences between the HAL-AR and CL-AR groups, except for the operation time and the size of the primary tumor. The operation time of the HAL-AR group was significantly shorter than that of the CL-AR group (p = 0.004), and the size of the primary tumor in the HAL-AR group was significantly larger than that of the CL-AR group (p = 0.019). The operating time of the HAL-AR group reached an earlier mean plateau than did that of the CL-AR group. Before and after reaching the plateau, there were no differences in the perioperative results between the two groups. The operating time for the HAL-AR group was significantly shorter than that of the CL-AR group after reaching a plateau (p = 0.012). The short-term outcomes for both groups were similar in terms of survival and recurrence (p = 0.996 and p = 0.476, respectively). CONCLUSION: Hand-assisted laparoscopic anterior resection has a shorter operative time than does CL-AR and is more successful than CL-AR for resecting larger tumors, while both procedures result in similar short-term oncologic outcomes. Hand-assisted laparoscopic anterior resection is thought be a comparable operative technique for anterior resection of left-sided colon cancer.
