Key result
Hand-assisted laparoscopic surgery resulted in comparable 3-year relapse-free and overall survival rates to conventional laparotomy across all stages of colorectal cancer, while significantly reducing intraoperative blood loss.

Hand-assisted laparoscopic surgery for colorectal cancer offers comparable survival to conventional laparotomy while reducing surgical blood loss and hospital stay.
Tajima et al. (2014) conducted a cohort in Stage I/II/III colorectal cancer (n=212). Hand-assisted laparoscopic surgery (HALS) vs. Conventional laparotomy (CL) was evaluated on 3-year relapse-free survival (Stage I) (HR 0.781, 95% CI 0.280-2.181, p=0.671). Hand-assisted laparoscopic surgery resulted in comparable 3-year relapse-free and overall survival rates to conventional laparotomy across all stages of colorectal cancer, while significantly reducing intraoperative blood loss.
