RESUMEN

Background: Common bile duct exploration (CBDE) is performed uncommonly. Issues surrounding its uptake in the laparoscopic era include perceived difficulty and lack of training. We aim to determine the success of CBDE performed by "specialist" and "nonspecialist" common bile duct (CBD) surgeons to determine whether there is a substantial difference in success and safety. Methods: A 10-year retrospective audit was performed of patients undergoing CBD exploration for choledocholithiasis. Northern Health maintains an on-call available "specialist" CBD surgeon roster to aid with CBDE. Results: Five hundred fifty-one patients were identified, of which 489/551 (88.7%) patients had stones successfully cleared. Specialists had a higher success rate (90.8% versus 82.6%, P = .008), associated with a longer surgical time. Method (transcystic or transductal), approach (laparoscopic or open), and indication for operation were similar between groups. There was no significant difference in complications. To be confident of a surgeon having an 80% success rate, 70 procedures over 10 years were required, however, an "in-control" 50% success rate may only require 1 procedure per year. Conclusion: While specialist CBDE surgeons have improved success rates, nonspecialist general surgeons also have a good and comparable success rate with an equivalent complication rate. With realistic annual targets, nonspecialist CBD surgeons should be encouraged to perform CBDE in centers without specialist support.

RESUMEN

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) can be performed to treat choledocholithiasis at the time of laparoscopic cholecystectomy. The aim of this study was to identify factors that predict the success of LCBDE. MATERIALS AND METHODS: A retrospective audit was performed on patients who underwent LCBDE for the management of choledocholithiasis at Northern Health between 2008 and 2018. RESULTS: A total of 513 patients were identified with an overall success rate of 90.8%. Most LCBDE were done through a transcystic approach with the remainder through a choledochotomy. When comparing patients with a successful operation to those that were unsuccessful, univariate analysis demonstrated significant differences in preoperative white cell count and number of duct stones found. Age and elevated nonbilirubin liver function tests were found to be significant factors associated with the failure of LCBDE on multivariate analysis. The likelihood of a failed operation in those with multiple stones was observed to be almost halved compared with patients with single stone although this did not reach significance [odds ratio (OR): 0.53, 95% confidence interval (CI): 0.28-1.01, P=0.055]. Multivariate analysis indicated that unsuccessful procedures (OR: 10.13, 95% CI: 4.34-23.65, P<0.001) and multiple duct stones (OR: 3.79, 95% CI: 1.66-8.67, P=0.002) were associated with an increased risk of severe complications. CONCLUSIONS: A single impacted stone may be more difficult to remove, however complications were more likely to be associated with multiple duct stones. With no other clinically relevant predictive factors, and because of the high success of the procedure and the low morbidity, LCBDE remains an option for all patients with choledocholithiasis.

RESUMEN

Coronary artery disease (CAD) confers increased perioperative risk in patients undergoing liver transplantation (LT). Although routine screening for CAD is recommended, there are limited data on the effectiveness of screening strategies. We evaluated the safety and efficacy of a 3-tiered cardiac risk-assessment protocol that stratifies patients based on age and traditional cardiac risk factors. We peformed a single-center, prospective, observational study of consecutive adult patients undergoing LT assessment (2010-2017). Patients were stratified into low-risk (LR), intermediate-risk (IR), or high-risk (HR) cardiac groups and received standardized investigations with selective use of transthoracic echocardiography (TTE), dobutamine stress echocardiography (DSE), computed tomography coronary angiography (CTCA), and coronary angiography (CA). Primary outcomes were cardiac events (CEs) and cardiovascular death up to 30 days after LT. Overall, 569 patients were included, with 76 patients identified as LR, 256 as IR, and 237 as HR. Cardiac risk factors included diabetes mellitus (26.0%), smoking history (47.3%), hypertension (17.8%), hypercholesterolemia (7.2%), family (17.0%) or prior history of heart disease (6.0%), and obesity (27.6%). Of the patients, 42.0% had ≥2 risk factors. Overall compliance with the protocol was 90.3%. Abnormal findings on TTE, DSE, and CTCA were documented in 3, 23, and 44 patients, respectively, and 12 patients were not listed for transplantation following cardiac assessment (1 LR, 2 IR, and 9 HR). Moderate or severe CAD was identified in 25.4% of HR patients on CTCA following a normal DSE. CEs were recorded in 7 patients (1.2%), with 2 cardiovascular deaths (0.4%). Cardiac risk stratification based on traditional cardiac risk factors with the selective use of DSE, CTCA, and CA is a safe and feasible approach that results in a low perioperative cardiac event rate.
