Robot performs complex 'keyhole' intestinal surgery on pigs without human aid

A robot has successfully performed "keyhole" intestinal surgery on pigs without any aid from humans, according to a study from John Hopkins University (published in Science Robotics). What's more, the Smart Tissue Autonomous Robot (STAR) handled the tricky procedure "significantly better" than human doctors. The breakthrough marks a significant step towards automated surgery that could one day help "democratize" patient care, the researchers said. Laparoscopic or keyhole surgery requires surgeons to manipulate and stitch intestines and other organs through tiny incisions, a technique that requires high levels of skill and has little margin for error. The team chose to do "intestinal anastomosis" (joining two ends of an intestine), a particularly challenging keyhole procedure.
