Hand assisted laparoscopic surgery versus conventional laparoscopy for colorectal surgery

Despite the limited number of trials performed, meta-analysis demonstrated a statistically significant decrease in conversion rates among the hand assisted group. There was no difference in operating time or perioperative complication rates. Additional adequately powered and methodologically sound trials are needed to determine if there is a clinically important difference in perioperative outcomes. Due to significant costs associated with the use of hand-assist devices, economic analyses are also warranted.
