Incidence of Endoscopic Retrograde Cholangiography after Subtotal Fenestrating and Reconstituting Cholecystectomy.

BACKGROUND

Laparoscopic subtotal cholecystectomy (SC) is used for the difficult cholecystectomy, but published experience with resource utilization for SC is limited. We hypothesized that the need for advanced resources are common after SC.

STUDY DESIGN

Retrospective review of laparoscopic cholecystectomies between 2017 and 2021 at a large center. SC cases were identified using a medical record tool. Baseline characteristics were assessed with student's t-test and chi-squared. Primary outcome was ERC within 60-days. Secondary outcomes were reconstituted SC on post-op ERC and length of stay (LOS). Uni- and multivariable logistic regression were used for binary outcomes. Multiple linear regression was used for LOS. Covariates included age, sex, BMI, ASA class.

RESULTS

A total of 1222 laparoscopic cholecystectomies were performed between 2017 and 2021. Of these, 87 (7%) were SC. Male (p<0.001) and older (p<0.001) patients were more likely to undergo SC. Odds of post-op ERC were higher in the SC group (OR 9.79 95% CI 5.90, 16.23 p<0.001). There was no difference in pre-op ERC (17% vs 21% p=0.38). Reconstituting SC had lower odds of post-op ERC (OR 0.12, 0.023-0.58, p=0.009). LOS was 1.81 times higher in the SC group(p=<0.001). Post-op ERC was not associated with LOS (p=.24).

CONCLUSIONS

We present one of the largest single-center series of SC. SC patients are more likely to be male, older, have higher ASA class, and have increased LOS. SC should be performed when access to ERC and interventional radiology is available. Absent these adjuncts, reconstituting SC decreases the need for early ERC, but long-term outcomes are unknown.
