How effective is robot-assisted laparoscopic cholecystectomy?
All trials were at high risk of bias. In one trial, about one-sixth of the laparoscopic cholecystectomies in which robot assistance was used, required temporary use of a human assistant. The reviewers were unable to identify trials comparing one type of robot assistant with another.
About 10-15% of the adult Western population have gallstones¹,² and between 1% and 4% become symptomatic in a year.¹,² The role of a robotic assistant in laparoscopic cholecystectomy is controversial. 1.
