Laparoscopic left hepatectomy in a goat as a training model for laparoscopic anatomic liver resection: results of training courses with a total of 70 goats. Surg Endosc 2023; 37:3634-3641. [PMID: 36627539 DOI: 10.1007/s00464-023-09864-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 01/03/2023] [Indexed: 01/11/2023]
Abstract
BACKGROUND To create a suitable animal model for the training of laparoscopic anatomic liver resection, we performed left hepatectomy using a goat and found its suitability. We have since started using goats for wet-lab training and have gradually standardized the relevant procedures. Herein, we report our standardized training procedures using a goat and discuss its feasibility as a novel training model. METHODS The standardized wet-lab training courses of laparoscopic liver resection conducted on 62 tables with a total of 70 goats were reviewed. The training course began by encircling the hepatoduodenal ligament for the Pringle maneuver, which was repeated during the parenchymal dissection. Following partial liver resection of the left lateral section, left hepatectomy was performed by a standardized procedure for humans in which the liver was split, exposing the entire length of the middle hepatic vein trunk from the dorsal side after extrahepatic transection of the left Glissonean pedicle. If a goat deceased before initiating left hepatectomy, the training was restarted with a new goat. The surgical procedures were performed by surgeons of varying skill levels. RESULTS A total of 184 surgeons including 10 surgical residents participated in the training. Partial liver resection was initiated in 62 tables, with 8 (13%) dying during or after the procedure of partial liver resection. Subsequently, left hepatectomy was initiated in 61 and completed in 59 tables (98%), regardless of whether the goat survived or deceased, and was not completed in 2 tables (3%) due to time limitation. In 14 tables (23%), the goats deceased during the procedure, however, the procedure was completed. The causes of death were multifactorial, including massive bleeding, reperfusion injury after the Pringle maneuver, and carbon dioxide gas embolism. CONCLUSIONS Left hepatectomy in a goat is useful as a training model for laparoscopic anatomic liver resection.

Laparoscopic pelvic lymph node dissection in cadaver surgical training from the combined perspectives of urologists, gastroenterologists and gynecologists improves overall knowledge and technique: initial experience of multidisciplinary cadaver surgical training at a single institution in Japan. Anat Sci Int 2022; 97:303-306.

Abstract
Surgeons in Japan have recently become more familiar with cadaver surgical training (CST). Extended pelvic lymph node dissection (PLND) considering the vesicohypogastric fascia and ureterohypogastric nerve fascia is gradually being performed not only in urology, but also in gynecology and gastroenterology. We performed CST using a 76-year-old female cadaver who was fixed by the Thiel method, with the aim of confirming the differences in the extent of PLND performed by certified laparoscopic specialists in urology, gastroenterology and gynecology. Even in the common surgeries, there are still several areas where anatomical structures are poorly understood. In recent years, with the spread of robotic surgery, the techniques related to PLND in these three departments have gradually become similar. Through this CST program, we were able to understand the differences in procedures and the extent of PLND in these three departments. By continuing these CSTs, we hope that a standardized PLND procedure will be performed not only within the same department, but also between different departments, and that high-quality PLND will be safely performed.

Development of a novel educational tool to assess skills in laparoscopic liver surgery using the Delphi methodology: the laparoscopic liver skills scale (LLSS). Surg Endosc 2021; 36:2321-2333. [PMID: 33871719 DOI: 10.1007/s00464-021-08507-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 04/07/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND No specific performance assessment scales have been reported in laparoscopic liver resection. This study aimed at developing an objective scale specific for the assessment of technical skills for wedge resection in anterior segments (WRAS) and left lateral sectionectomy (LLS). METHODS A laparoscopic liver skills scale (LLSS) was developed using a hierarchical task analysis. A Delphi method obtained consensus among five international experts on relevant steps that should be included into the LLSS for assessment of operative performances. The consensus was predefined using Cronbach's alpha > 0.80. RESULTS A semi-structured review extracted 15 essential subtasks for full laparoscopic WRAS and LLS for evaluation in the Delphi survey. Two rounds of the survey were conducted. Three over 15 subtasks did not reach the predefined level of consensus. Based on the expert's comments, 13 subtasks were reformulated, 4 subtasks were added, and a revised skills scale was developed. After the 2nd round survey (Cronbach's alpha 0.84), 19 subtasks were adopted. The LLSS was composed of three main parts: patient positioning and intraoperative preparation (task 1 to 8), the core part of the WRAS and LLS procedure (tasks 9 to 14), and completion of procedure (task 15 to 19). CONCLUSIONS The LLSS was developed for measuring the skill set for the education of safe and secure laparoscopic WRAS and LLS procedures in a dedicated training program. After validation, this scale could be also used as an assessment tool in the operating room and extrapolated as an operative roadmap to other complex procedures.

The Thiel cadaveric model for pelvic floor surgery: Best rated in transferable simulation-based training for postgraduate studies. Eur J Obstet Gynecol Reprod Biol 2020; 256:165-171.

Abstract
OBJECTIVE To determine whether the Thiel cadaveric model is better and more realistic than other surgical simulation techniques for learning pelvic floor and perineal surgical procedures according to the opinions of urogynecologists and surgeons participating in international postgraduate pelvic floor surgery courses using cadavers embalmed by the Thiel method. STUDY DESIGN An observational prospective study was performed in urogynecologists and surgeons attending international postgraduate pelvic floor and perineal surgery courses using cadavers embalmed by the Thiel method. A survey was completed by the participants after finishing the course. Based on the answers collected, we analyzed the differences, including in the satisfaction degree and teaching level for each surgical procedure, between different surgical simulation models that the participants had already used and the Thiel simulation method employed. RESULTS The students recognized that Thiel cadavers present more similarities to patients than other simulation methods. The Thiel cadaveric method was considered by most responders to be the best for the simulation of surgical procedures on the pelvic floor and perineum. Most of the surgeons surveyed recommended conducting these courses with Thiel cadavers for different colleagues in other specialties as a reliable simulation method for training for difficult surgical procedures. CONCLUSIONS Participants in the course on pelvic floor surgery in Thiel cadavers recognized that this is the most realistic model for surgical simulation and the best way to gain confidence, self-determination and precise surgical skills for performing pelvic floor and perineal surgery.
