Advanced technology in surgery

Robotics in endoscopy

PURPOSE OF REVIEW

The increasing complexity of intralumenal and emerging translumenal endoscopic procedures has created an opportunity to apply robotics in endoscopy. Computer-assisted or direct-drive robotic technology allows the triangulation of flexible tools through telemanipulation. The creation of new flexible operative platforms, along with other emerging technology such as nanobots and steerable capsules, can be transformational for endoscopic procedures. In this review, we cover some background information on the use of robotics in surgery and endoscopy, and review the emerging literature on platforms, capsules, and mini-robotic units.

RECENT FINDINGS

The development of techniques in advanced intralumenal endoscopy (endoscopic mucosal resection and endoscopic submucosal dissection) and translumenal endoscopic procedures (NOTES) has generated a number of novel platforms, flexible tools, and devices that can apply robotic principles to endoscopy. The development of a fully flexible endoscopic surgical toolkit will enable increasingly advanced procedures to be performed through natural orifices.

SUMMARY

The application of platforms and new flexible tools to the areas of advanced endoscopy and NOTES heralds the opportunity to employ useful robotic technology. Following the examples of the utility of robotics from the field of laparoscopic surgery, we can anticipate the emerging role of robotic technology in endoscopy.

Telementoring: an important enabling tool for the community surgeon

This study evaluated the efficacy of telementoring as an enabling tool for community general surgeons to perform advanced laparoscopic surgical procedures. We present a series of 19 patients who underwent advanced laparoscopic surgical procedures in two community hospitals, between November 2002 and July 2003, by four community surgeons with no formal advanced laparoscopic training. Each surgeon was telementored by an expert surgeon from a tertiary care hospital. Telementoring was achieved with real-time two-way audio-video communications over Internet Protocol or Integrated Services Digital Network lines with bandwidths from 385 kbps to 1.2 mbps. The procedures included 10 bowel resections, 5 Nissen fundoplications, 2 splenectomies, 1 reversal of a Hartmann procedure, and 1 ventral hernia repair. Two of the 19 procedures (11%) were converted to open. There were no intraoperative complications and two postoperative complications (11%). The primary surgeon considered telementoring useful in all cases (median score, 4 of 5). The mentor was also comfortable with the quality of the laparoscopic surgery performed (median score, 4 of 5). Telecommunication bandwidth for audio and video transmission was found to be a critical factor in the quality of telementoring process. Telementoring is safe and feasible. It allows community surgeons with no formal advanced laparoscopic training to benefit from expert intraoperative advice during the performance of advanced laparoscopic procedures. It may also reduce health-care costs by avoiding the need to refer and transfer patients to tertiary care centers.

Improving efficiency in endoscopy with robotic technology

The adoption of robotic systems will alter endoscopy suite environments in terms of staff roles, work processes, and the physical layout and design of the workspace.
