Short-term Outcomes of Hand-Assisted Laparoscopic Surgery vs. Open Surgery on Right Colon Cancer: A Case-Controlled...

This study was designed to evaluate short-term clinical outcomes by comparing hand-assisted laparoscopic surgery with open surgery for right colon cancer.

Sixteen patients who underwent a hand-assisted laparoscopic right hemicolectomy (HAL-RHC group) and 33 patients who underwent a conventional open right hemicolectomy (open group) during the same period were enrolled in this study with a case-controlled design.

The operation time was 217 minutes in the HAL-RHC group and 213 minutes in the open group (P = 0.389). The numbers of retrieved lymph nodes were similar between the two groups (31 in the HAL-RHC group and 36 in the open group, P = 0.737). Also, there were no significant difference in the incidence of immediate postoperative leukocytosis, the administration of additional pain killers, and the postoperative recovery parameters. First flatus was shown on postoperative days 3.5 in the HAL-RHC group and 3.4 in the open group (P = 0.486). Drinking water and soft diet were started on postoperative days 4.8 and 5.9, respectively, in the HAL-RHC group and similarly 4.6 and 5.6 in the open group (P = 0.402 and P = 0.551). The duration of hospital stay was shorter in the HAL-RHC group than in the open group (10.3 days vs. 13.5 days, P = 0.048). No significant difference in the complication rates was shown between the two groups, and no postoperative mortality was encountered in either group.

The patients with right colon cancer in the HAL-RHC group had similar pathologic and postoperative recovery parameters to those of the patients in the open group. The patients in the HAL-RHC group had shorter hospital stays than those in the open group. Therefore, hand-assisted laparoscopic right hemicolectomy for right-sided colon cancer is feasible.
