Background:
This is a retrospective cohort of patients undergoing laparoscopic cholecystectomy with intraoperative cholangiography (IOC) with positive findings for filling defects. We comparatively assessed differences in complication risks for patients that had their cholangiography catheter maintained in its transcystic duct (TCD) position postoperatively. This is a practice proposed to overcome the limited availability of Endoscopic Retrograde Cholangiopancreatography (ERCP) as well as to avoid surgical exploration of the common bile duct.
Methods:
Retrospective medical record review of all positive IOC from January 2015 to December 2018 were assessed. Patients' demographic and perioperative data from the hospital stay period in which the cholecystectomy occurred until the last surgical ambulatory visit for perioperative characteristics were compared between groups (with vs. without TCD catheter). Complications were operationalized using the Clavien-Dindo scale.
Results:
Univariate analysis of complications showed a 2.4-fold risk increase in complications (95% CI 1.13-5.1) between comparison groups. Number of ERCPs (18 vs. 30), and MRCPs (5 vs. 17) were not significantly different between maintaining or not the TCD catheter postop, respectively. Stratified analysis followed by exact logistic regression supported the findings that maintaining the TCD catheter postoperatively increased complication rates (OR = 5.34, 95% CI 1.22, 29.83, p = 0.022), adjusting for potential confounders.
Conclusion:
The maintenance of the TCD catheter postoperatively did not prove to be effective in significantly reducing the number of ERCP nor associated complications. Also, outcomes inherited from the practice caused adverse events that surpassed its potential benefits. Moreover, expectant follow-up is reasonable for patients with evidence of common bile duct stones, even in setting with limited resource availability. We do not recommend this practice, even in settings where there are limited resources of more modern management of choledocholithiasis.
