Malfunctions in real with da Vinci surgery

Abstract: "Robotic surgery (RS) technology has undergone rapid growth in the surgical field since its approval. In clinical practice, failure of robotic procedures mainly results from a surgeon’s inability or to a device malfunction. We reviewed the literature to estimate the impact of this second circumstance in RS and its consequent legal implications. According to data from the literature, device malfunction is rare. We believe it is necessary to complement surgical training with a technical understanding of RS devices." 

The conclusion: "– In   clinical   practice,   failure   of   robotic   procedures    mainly results from a surgeon’s inability or to a device  dysfunction.
– The  likelihood  of  the  a  patient’s  being  damaged  not   directly by the actions of the operator, but rather from  the  RS  device,  has  always  been  a  debated  among   robotic surgeons and legal medicine specialists.
– The  learning  curve  involved  in  RS  should  consider   both a purely technical part and a part to master the  use of the device and resolution of technical problems.
In total, from 2005  to 2014, 386 malfunctions were described out of 14141 procedures (2.7%), 20.9% of which was damage caused by malfunc - tion of the RS arms and instruments. The total percentage  of conversion in reported cases was about 2%. From a RS  malfunction, 16 caused patient damage, of which 13 were  mild and resolved without sequelae, and 3 were complex,  including  an  external  iliac  vein  lesion,  ileal  perforation,   and  urethral  lesion."
