Evaluation of the knowledge of the critical view of safety and recognition of the transoperative complexity during the laparoscopic cholecystectomy.

Introduction: Since the establishment of the Critical view of safety (CVS), different strategies have been created such as bailout procedures (SC, subtotal cholecystectomy), classifications for preoperative and intraoperative complexity (The Parkland grading scale, PGS) and objective evaluation of the CVS (doublet score, DS) to establish a "Culture of Safety in Cholecystectomy, COSIC"; to avoid complications.

Methods: A multiple choice questionnaire was applied to residents and graduated surgeons from different Hospitals in Mexico during different national meetings; evaluating the knowledge of this different concepts (CVS, SC, PGS, DS), univariate logistic regression was used to assess the association of the knowledge with adverse events (AE) like the Bile duct injury.

Results: A total of 744 questionnaires were evaluated; 284 (38.17%) women and 460 (61.83%) men; 436 (58.6%) were residents and 308 (41.4%) graduated surgeons. 708 (95.16%) reported knowing the CVS; however, only (51.98%, p ≤ 0.001) defined the concept correctly, while 136 (18.28%) reported knowing the DS, but only 44 (5.91%) defined it correctly. Regarding the PGS, 398 (53.49%) mentioned knowing it, but only 262 defined it correctly. The concept of SC 642 (86.29%) reported knowing it; however, only (56.7%, p ≤ 0.001) correctly defined the techniques, being the reconstituting technique the preferred one (42.37% vs 34.89%). In this survey, the correct knowledge of the CVS (OR 0.47, p < 0.001), the subtotal techniques (OR 0.71 p = 0.07), the DS (OR 0.48 p < 0.001) and of the PGS (OR 0.28, p < 0.001) decreased the risk of presenting BDI.

Conclusion: Despite the COSIC and the timing of publication of the CVS; the percentage of people who can correctly define basic safety concepts is low among residents and licensed surgeons. Therefore, it is important to emphasize the dissemination of these concepts to obtain safe LC and thus reduce the incidence of complications.
