Impact of bedside assistant on outcomes of robotic thyroid surgery: A STROBE-compliant retrospective case-control study

Experience matters for robotic assistance: an analysis of case data

Many robotic procedures require active participation by assistants. Most prior work on assistants' effect on outcomes has been limited in procedural focus and scope, with studies reporting differing results. Knowing how assistant experience affects operating room time could inform operating room case scheduling and provide an impetus for additional assistant training. As such, this retrospective cohort study aimed to determine the association between assistant experience and operating room time for 2291 robotic-assisted operations performed from 2016 to 2022 at our institution. Linear regression showed a significant association between the presence of a junior resident and increased case length differential with an increase of 26.9 min (p = 0.01). There were no significant associations between the presence of a senior resident (p = 0.52), presence of a fellow (p = 0.20), or presence of a physician assistant (p = 0.43) and case length differential. The finding of increased operating room time in the presence of a junior resident during robotic cases supports consideration of the adoption of formal assistant training programs for residents to improve efficiency.

The effect of bedside assistant technical performance on outcomes in robotic surgery

Technical performance in surgery has been associated with patient outcomes. Robotic surgery is unique in that both a console surgeon and bedside surgeon are required. A systematic review according to PRISMA guidelines identified all pertinent literature regarding skill level of the bedside assistant with regards to patient outcomes in robotic surgery. 10 studies met inclusion criteria. In all studies, the skill level of the assistant was based on experience, either by post-graduate year of the resident or number of cases previously performed by the assistant. Five studies reported significant, shorter operative times with increasing experience of the bedside assistant. No study reported a significant difference in postoperative outcomes. The existing literature fails to show improved patient outcomes with more experienced bedside assistants in robotic surgery. Metrics should be developed to measure actual technical performance of the bedside assistant rather than using arbitrary assessments of experience in future studies.

Improving ergonomics for the bedside assistant in robotic colorectal surgery

The aim of the study was to document when significant bedside assistant (BA) and robotic arm collisions occurred during robotic colorectal surgery (RCS). An observational study of 10 consecutive RCS cases, from May 2022 to September 2022, was performed. Situations when there was significant collision between BA arm and robotic arm (to cause inadvertent movement of the assistant instrument) were documented. The assistant port was randomly placed to the right or the left side of the camera port. Situations which led to detrimental BA ergonomics include dissection at the most peripheral working field, proximity of the target (mesenteric vessels), small bowel retraction, placement of the assistant port in the medial position (on the left side of the camera port), during intra-corporeal suturing and robotic stapler use. The robotic console surgeon can predictably identify and avoid situations when injury to the BA may occur.

The role of the bedside assistant in robot-assisted surgery: A critical synthesis

INTRODUCTION

Robot-assisted surgery has grown exponentially since its inception and first approval in the United States in the year 2000. The surgeon operating with the assistance of the robot sits remotely to the patient and another practitioner assists at the bedside. The role of the bedside assistant and the training that is required to undertake this role are understudied topics.

AIM

To explore the functions, training and professional development of the bedside assistant in robot-assisted surgery and propose the necessary foundations for the safe enactment of the role in the United Kingdom.

METHODS

Through critical interpretative synthesis, relevant literature was systematically searched and analysed to inform integration of evidence.

RESULTS

Seventy-three studies were retrieved from the literature, across several health care disciplines and surgical specialities. These were critically analysed to inform a theoretically sound account grounded on evidence.

CONCLUSION

The role, functions and skills of the bedside assistant in robot-assisted surgery vary across contexts. These were analysed and critically synthetised to produce several keys to the success of bedside assistants in robot-assisted surgery in the context of the United Kingdom and of its national regulations.

Introduction of robotic surgery does not negatively affect cardiothoracic surgery resident experience

The objective of this study was to evaluate the educational impact following the implementation of a robotic thoracic surgery program on cardiothoracic (CT) surgery trainees. We hypothesized that the introduction of a robotic thoracic surgery program would adversely affect the CT surgery resident experience, decreasing operative involvement and subsequent competency of surgical procedures. CT surgery residents and thoracic surgery attendings from a single academic institution were administered a recurring, electronic survey from September 2019 to September 2020 following each robotic thoracic surgery case. Surveys evaluated resident involvement and operative performance. This study was exempt from review by our Institutional Review Board. Attendings and residents completed surveys for 86 and 75 cases, respectively. Residents performed > 50% of the operation independently at the surgeon console in 66.2 and 73.3% of cases according to attending and resident responses, respectively. The proportion of trainees able to perform > 75% of the operation increased with each increasing year in training (p = 0.002). Based on the Global Evaluative Assessment of Robotic Skills grading tool, third-year residents averaged higher scores compared to first-year residents (22.9 versus 17.4 out of 30 possible points, p < 0.001), indicating that more extensive prior operative experience could shorten the learning curve of robotic thoracic surgery. CT surgery residents remain actively involved in an operative role during the establishment of a robotic thoracic surgery program. The transition to a robotic thoracic surgery platform appears feasible in a large academic setting without jeopardizing the educational experience of resident trainees.
