Background: We tested the added value of 3D-vision on procedure time and surgical performance during robotic pancreatoduodenectomy anastomoses in biotissue. Robotic surgery has the advantage of articulating instruments and 3D-vision. Consensus is lacking on the added value of 3D-vision during laparoscopic surgery. Given the improved dexterity with robotic surgery, the added value of 3D-vision may be even less with robotic surgery.
Methods: In this experimental randomized controlled cross-over trial, 20 surgeons and surgical residents from 5 countries performed robotic pancreaticojejunostomy and hepaticojejunostomy anastomoses in a biotissue organ model using the da Vinci® system and were randomized to start with either 3D- or 2D-vision. Primary endpoint was the time required to complete both anastomoses. Secondary endpoint was the objective structured assessment of technical skill (OSATS; range 12-60) rating; scored by two observers blinded to 3D/2D.
Results: Robotic 3D-vision reduced the combined operative time from 78.1 to 57.3 min (24.6% reduction, p < 0.001; 20.8 min reduction, 95% confidence intervals 12.8-28.8 min). This reduction was consistent for both anastomoses and between surgeons and residents, p < 0.001. Robotic 3D-vision improved OSATS performance by 6.1 points (20.8% improvement, p = 0.003) compared to 2D (39.4 to 45.1 points, ± 5.5).
Conclusion: 3D-vision has a considerable added value during robotic pancreatoduodenectomy anastomoses in biotissue in both time reduction and improved surgical performance as compared to 2D-vision.

Background: Anastomotic suturing is the Achilles heel of pancreatic surgery. Especially in laparoscopic and robotically assisted surgery, the pancreatic anastomosis should first be trained outside the operating room. Realistic training models are therefore needed.

Background: Robotic surgery may improve surgical performance during minimally invasive pancreatoduodenectomy as compared to 3D- and 2D-laparoscopy but comparative studies are lacking. This study assessed the impact of robotic surgery versus 3D- and 2D-laparoscopy on surgical performance and operative time using a standardized biotissue model for pancreatico- and hepatico-jejunostomy using pooled data from two randomized controlled crossover trials (RCTs).
Methods: Pooled analysis of data from two RCTs with 60 participants (36 surgeons, 24 residents) from 11 countries (December 2017-July 2019) was conducted.
Development of a Senior Medical Student Robotic Surgery Training Elective.

As robotic surgery has become more widespread, early exposure to the robotic platform is becoming increasingly important, not only to graduate medical education, but also for medical students pursuing surgical residency. In an effort to orient students to robotic technology and decrease the learning curve for what is likely to become an integral part of residency training, we created a formal, elective robotic surgery curriculum for senior medical students. Throughout this 2-week fourth year rotation, students completed online training modules and assessment; mastered exercises on the simulator system related to the console, camera, energy, dexterity, and suturing skills; attended didactics; utilized the dual console during one-on-one simulation lab sessions with attending robotic surgery experts; and translated new skills to biotissue anastomoses as well as bedside-assisting in the operating room.

Background: It is currently unclear what the added value is of 3D-laparoscopy during pancreatic and biliary surgery. 3D-laparoscopy could improve procedure time and/or surgical performance, for instance in demanding anastomoses such as pancreatico- and hepaticojejunostomy. The impact of 3D-laparoscopy could be negligible in more experienced surgeons.
