Failing to prepare: the erosion of intraoperative cholangiography in the rising surgical workforce-a national review of general surgery residents' laparoscopic cholecystectomy and intraoperative cholangiogram experience.

Background: With the advent of advanced imaging and endoscopy, we hypothesized that IOC resident training has declined and is currently insufficient. To this end, we evaluated the national general surgery resident experience with laparoscopic cholecystectomy both with and without intraoperative cholangiography.

Methods: The National Accreditation Council for Graduate Medical Education (ACGME) operative logs were evaluated from 2012 to 2023 for general surgery residents. The number of completed laparoscopic cholecystectomy (CCY) operations and CCY with cholangiogram were evaluated and compared by postgraduate year, program (academic, community, hybrid, military), and resident role (first assistant, surgeon junior, and surgeon chief). ANOVA testing was used to analyze the data.

Results: The cholecystectomy case volumes of graduating general surgery residents in all cholecystectomies increased between the 2012-2013 and 2022-2023 academic years (123.9 v 143, p < 0.01). The number of performed CCY + IOC declined significantly over this period (25.1 v 21.6, p = 0.02). University-affiliated programs demonstrated statistically lower numbers of IOCs than community-based (19.3 v 34.1, p < 0.01), hybrid (24.0, p < 0.01), or military programs (26.3, p < 0.01). Community-based programs performed more CCY with IOC than any other group (p < 0.01). Despite the number of CCY + IOC declining during the study period, an increasing percentage of the CCY + IOC were performed by chief (PGY5) residents (p < 0.01).

Conclusion: Trainee experience with IOC is declining. The decreased rate and number of IOCs performed by residents has correlated with a "seniorization" of resident experience. This change may result in a future general surgeon workforce with inadequate IOC experience and ultimately impact patient safety. To bolster experience with both technique and interpretation, liberal IOC should be advocated for in training environments. A national IOC assessment may be necessary to address this looming deficit.
