Robo-surgery: As Safe And Capable As Human Assistant In Key-hole Gallbladder Removal

Summary:
Using a robotic assistant to remove a patient's gallbladder by key-hole surgery (laparoscopic cholecystectomy) is as safe as working with a human assistant, a Cochrane Review has concluded. Comparisons between robot- and human-assisted surgery showed that there were no differences in terms of morbidity, the need to switch to open surgery, total operating time, or length of stay in hospital.

Using a robotic assistant to remove a patient's gallbladder by key-hole surgery (laparoscopic cholecystectomy) is as safe as working with a human assistant, a Cochrane Review has concluded. Comparisons between robot- and human-assisted surgery showed that there were no differences in terms of morbidity, the need to switch to open surgery, total operating time, or length of stay in hospital.

Between 10 and 15% of the adult western population develop gallstones, placing a huge demand on health services. In the USA alone, more than 500,000 people have their gall bladder removed each year. The preferred way of doing this is now to use keyhole surgery that involves a surgeon and an assistant. In key-hole surgery, the surgeon sees inside the patient via a long camera introduced through a 1 cm abdominal cut. The camera guides the surgeon in using the surgical instruments introduced through other small cuts (ranging from 0.5 to 1 cm). The assistant's job is to move the camera, which acts as the surgeon's eyes.

A range of robots can now perform this task: this study looked at trials involving 'Endoassist', 'Aesop', 'Passist' and 'Zeus'.

To assess how well robots were performing, a team of researchers considered data from five randomised trials that included a total of 453 patients. The results showed a marginal (though not statistical) decrease in the numbers of gallbladders that burst during robot-assisted surgery, but overall there was no appreciable difference.

"We need more trials that see whether the success rates using robotic assistants increase once surgeons have more experience using them," said lead researcher Kurinchi Gurusamy, who works at the University Department of Surgery at the Royal Free Hospital, London.

One of the aims behind using robots is that it could enable a surgeon to perform an emergency operation without having to wait for a human assistant to become available. This could have distinct advantages in countries where there are limits to the numbers of hours assistants are allowed to work.

Current data suggest that we are not yet at that point. "Robotic assistants seem to be an exciting possibility, but we are not yet at the stage that they should be used as replacements for human assistants," says Gurusamy.
