Increasing resident utilization and recognition of the critical view of safety during laparoscopic cholecystectomy: a pilot study from an academic medical center

Background Laparoscopic cholecystectomy (LC) is a commonly performed surgical procedure; however, it is associated with an increased rate of bile duct injury (BDI) when compared to the open approach. The critical view of safety (CVS) provides a secure method of ductal identification to help avoid BDI. CVS is not universally utilized by practicing surgeons and/or taught to surgical residents. We aimed to pilot a safe cholecystectomy curriculum to demonstrate that educational interventions could improve resident adherence to and recognition of the CVS during LC. Methods Forty-three general surgery residents at Thomas Jefferson University Hospital were prospectively studied. Fifty-one consecutive LC cases were recorded during the pre-intervention period, while the residents were blinded to the outcome measured (CVS score). As an intervention, a comprehensive lecture on safe cholecystectomy was given to all residents. Fifty consecutive LC cases were recorded post-intervention, while the residents were empowered to “time-out” and document the CVS with a doublet photograph. Two independent surgeons scored the videos and photographs using a 6-point scale. Residents were surveyed pre- and post-intervention to determine objective knowledge and self-reported comfort using a 5-point Likert scale. Results In the 18-week study period, 101 consecutive LCs were adequately captured and included (51 pre-intervention, 50 post-intervention). Patient demographics and clinical data were similar. The mean CVS score improved from 2.3 to 4.3 ( p 4 increased from 15.7 to 52 % ( p
