Purpose:
The aim of this study was to compare oncologic outcomes and perioperative variables following conventional laparoscopic surgery (LAP) versus hand-assisted laparoscopic surgery (HALS) for rectal cancer.
Methods:
Between January 2008 and December 2012, 2680 consecutive patients who underwent curative resection for rectal cancer were analyzed. We used 1:1 propensity score matching to adjust for potential baseline confounders between groups including age, sex, body mass index, American Society of Anesthesiologists score, tumor distance from the anal verge, clinical T and N categories, pathologic T and N categories, preoperative carcinoembryonic antigen level, and the status of preoperative concurrent chemoradiotherapy. After matching, we analyzed 278 patients in each group (n = 556).
Results:
The median follow-up period was 36.2 and 37.4 months in the HALS group and the conventional LAP group, respectively. Postoperative complications were not significantly different between the two groups (P = 0.531). The 5-year overall survival rate was 88.8 % in the HALS group and 91.2 % in the conventional LAP group (P = 0.329). The 5-year disease-free survival rate was 77.0 % in the HALS group and 79.7 % in the conventional LAP group (P = 0.591).
Conclusions:
HALS is considered a safe and feasible approach for rectal cancer treatment that enables the preservation of the advantages of conventional laparoscopic surgery.
