Purpose: To investigate the applicability, safety, short-term and long-term outcomes of laparoscopic surgery in the treatment of right-sided colon carcinomas with D3 lymphadenectomy.
Methods: Between June 2003 and September 2010, 324 patients with right-sided colon carcinoma underwent surgical treatment in the same hospital, 177 cases were treated by laparoscopic surgery (LRH group) and 147 cases by open surgery (ORH group). We performed a retrospective analysis of the differences between the two groups in terms of the clinical data.
Results: There were no significant differences between the two groups in the demographic data; however, the recovery time was significantly shorter in the LRH group, the number of overall lymph nodes harvested and principle lymph nodes harvested in the LRH group was significantly higher than in the ORH group, the incidence of postoperative complications was 12.99 % in the LRH group and 22.45 % in the ORH group (P < 0.05), and the recurrence rate in the LRH group was lower than that in the ORH group, although the difference was not significant (15.25 vs 19.73 %). The cumulative overall survival for all stages at 1, 3 and 5 years in the LRH group (97.18, 83.73 and 70.37 %) were not significantly different compared to those in the ORH group (94.56, 77.84 and 66.97 %).
Conclusions: Laparoscopic-assisted right hemicolectomy with D3 lymphadenectomy for colon carcinomas is safe and effective, while it is also superior to open surgery regarding the short-term outcomes, and the long-term outcomes are similar to those of open surgery.
