Sheetz KH, et al. - Researchers explored outcomes of and trends in the use of robotic, laparoscopic, and open colectomy across diverse practice settings. They performed a population-based study of Medicare beneficiaries undergoing elective colectomy between January 2010 and December 2016. The instrumental variable analysis was applied to account for both measured and unmeasured differences in individual characteristics between robotic, open, and laparoscopic colectomy procedures. They examined data between January 21, 2019, and March 1, 2019. They enrolled a sum of 191,292 procedures (23,022 robotic procedures [12.0%], 87,639 open procedures [45.8%], and 80,631 laparoscopic colectomy procedures [42.0%]). The results showed that surgeons and hospitals should continue to question the value of robotics for colectomy.
