Patients and hospital managers want laparoscopic simulation training to become mandatory before live operating: a multicentre qualitative study of stakeholder perceptions

Training curriculum in minimally invasive emergency digestive surgery: 2022 WSES position paper

BACKGROUND

Minimally invasive surgery (MIS), including laparoscopic and robotic approaches, is widely adopted in elective digestive surgery, but selectively used for surgical emergencies. The present position paper summarizes the available evidence concerning the learning curve to achieve proficiency in emergency MIS and provides five expert opinion statements, which may form the basis for developing standardized curricula and training programs in emergency MIS.

METHODS

This position paper was conducted according to the World Society of Emergency Surgery methodology. A steering committee and an international expert panel were involved in the critical appraisal of the literature and the development of the consensus statements.

RESULTS

Thirteen studies regarding the learning curve in emergency MIS were selected. All but one study considered laparoscopic appendectomy. Only one study reported on emergency robotic surgery. In most of the studies, proficiency was achieved after an average of 30 procedures (range: 20-107) depending on the initial surgeon's experience. High heterogeneity was noted in the way the learning curve was assessed. The experts claim that further studies investigating learning curve processes in emergency MIS are needed. The emergency surgeon curriculum should include a progressive and adequate training based on simulation, supervised clinical practice (proctoring), and surgical fellowships. The results should be evaluated by adopting a credentialing system to ensure quality standards. Surgical proficiency should be maintained with a minimum caseload and constantly evaluated. Moreover, the training process should involve the entire surgical team to facilitate the surgeon's proficiency.

CONCLUSIONS

Limited evidence exists concerning the learning process in laparoscopic and robotic emergency surgery. The proposed statements should be seen as a preliminary guide for the surgical community while stressing the need for further research.

Portable Endoscopic Simulator for Urological Training: A Face/Content and Construct Validity Study

Mastering a surgical skill requires experience and repetition, yet opportunities for surgical trainees to gain real experience is variable and limited by case load. Surgical simulators have emerged in an attempt to overcome these limitations. However, the few currently available skills simulators for flexible endoscopy are costly, have limited accessibility and versatility, lack portability, and require dedicated time for practice. The use of a portable skills simulator to teach flexible endoscopy may provide a feasible alternative. This study introduces a novel, low-cost, portable, endoscopic simulation system for training basic endoscopic skills. Using custom software, the simulator presents a virtual environment featuring 3D models of anatomy, endoscopes, and endoscopic tools. The virtual endoscope and its tools are directly controlled in the simulation by motion input from a custom-manufactured portable endoscopic controller that communicates data via a Bluetooth interface. This two-part study presents proof of concept and initial pilot data examining the face/content validity and preliminary construct validity of the portable endoscopic simulator. In part one, experts (n = 2) and novices (n = 6) provided ratings of fidelity and utility as a training tool. In part two, experts (n = 4) and novices (n = 4) completed 10 simulated sequential basic endoscopic tasks and time to completion was assessed. Findings indicate that the simulator has good utility as a training tool, but some features require modification to be more realistic. Further, both novices and experts improved on the task with repeated measurements (p < .001), but there were no significant differences between experts and novices in time to completion. Although more robust validation is required, this simulator appears promising as a feasible and cost-effective tool for providing simulation training on basic endoscopic skills.
