The Safe Cholecystectomy: Evaluating the Use of Laparoscopic Subtotal Cholecystectomy Between Junior and Senior...

Laparoscopic Subtotal Cholecystectomy (SC) is a technique for performing safe cholecystectomy when excessive inflammation prevents exposure of the Critical View of Safety. Studies have evaluated outcomes and complications of laparoscopic cholecystectomy (LC), with mixed results in terms of surgeon experience. It is unclear if the rate of SC is associated with experience. We hypothesized that the rate of SC would decrease as surgical experience increased.

We performed a retrospective review of LC performed at an academic medical center. Demographics were analyzed using descriptive statistics. We performed a multivariable logistic regression to examine the relationship between years in practice and performance of SC. We performed a sensitivity analysis comparing those in their first year on faculty with all others.

Between November 1, 2017, and November 1, 2021, there were 1222 LC performed. 771 patients (63%) were female. 89 patients (7.3%) underwent SC. There were no bile duct injuries requiring reconstruction. Controlling for age, sex, and ASA class, there was no difference in the rate of SC by years of experience (OR .98, 95% CI .94-1.01). In a sensitivity analysis comparing first-year faculty to those beyond their first year, there was also no difference (OR .76, 95% CI 0.42-1.39).

We find no difference in the rate of performance of SC between junior and senior faculty. This reflects consistency, in keeping with best practice guidelines. This could be confounded by junior faculty requesting assistance during difficult operations. Further investigation into factors affecting decision-making may clarify this.
