Background:
Even though the goal of safely performing cholecystectomy is already a priority in general surgical training programs, we aimed to study how many residents and attendings reached the critical view of safety (CVS) in laparoscopic cholecystectomy.
Materials And Methods:
Retrospective review of prospectively collected data of all patients with biliary surgical conditions, which underwent laparoscopic cholecystectomy and their corresponding postoperative notes with self-reported CVS from May 2019 to May 2020 in an academic hospital. Comparisons of operative variables between postgraduate year and attendings were made.
Results:
Laparoscopic cholecystectomy was performed in 126 elective cases (62.6%) and 75 (37.3%) emergency cases. On 105 (83.3%) of the elective cases and on 54 (66.7%) emergency cases, a CVS was successfully performed. PGY3 and PGY5 had higher odds of achieving CVS compared to attendings OR 6.09 (95% CI 2.05 to 8.07) and 4.51 (95% CI 1.0 to 10.20), respectively. Overall, attendings had decreased odds ratio of achieving CVS of 0.488 when compared to all residents. Elective procedures had increased odds ratios of achieving CVS of 3.44 (95% CI 1.52 to 7.74). On elective cases, attendings performed significantly faster procedures when compared to PGY2-4, but not PGY5. No differences were seen between operative speeds between PGY. Third-year residents were identified as having the highest frequency of CVS; however, these differences were not statistically significant. In emergency cases, blood loss, operative time, CVS, and bile duct injuries revealed non-significant differences between operators.
Conclusion:
CVS was reached significantly more often in elective than in emergency surgeries. There is still a lack of residents and attending surgeons who still failed to complete CVS during LC, highlighting the need for further education. Future studies should be attempted to repeat this study with a larger sample size and multiple coaching sessions to determine long-term efficacy.
