LC-First vs. ERCP-First Approach for Cholecystocholedocholithiasis

Medical researchers have evaluated the efficacy and safety of two different sequencing methods for patients undergoing a single-stage surgical intervention for cholecystocholedocholithiasis (CCL), a condition involving stones in both the gallbladder and the common bile duct.

The treatment strategy involves combining laparoscopic cholecystectomy (LC), the surgical removal of the gallbladder, and endoscopic retrograde cholangiopancreatography (ERCP), a procedure used to remove stones from the bile duct.

While combining these procedures into a single operative session has gained popularity due to financial considerations and patient satisfaction, the optimal order of the procedures—whether to perform LC first or ERCP first—has remained a point of clinical debate.

Comparative Findings on Operative Efficiency

A retrospective comparative cohort study involving 115 patients who underwent the combined procedure between January 2021 and December 2023 analyzed the outcomes of these two approaches. The patients were divided into Group A, which received the ERCP-first approach, and Group B, which received the LC-first approach.

The study found that the LC-first approach offered a significant advantage in terms of time efficiency. The mean total operative time for the combined procedures was 75.1 ± 19.3 minutes for Group B, compared to 81.9 ± 16.7 minutes for Group A.

Specifically, the mean duration of the laparoscopic cholecystectomy was significantly shorter in the LC-first group (37.2 ± 12.2 minutes) than in the ERCP-first group (41.2 ± 8.98 minutes).

Conversely, the duration of the ERCP procedure itself was comparable between the two groups, with Group A averaging 43.3 ± 11.8 minutes and Group B averaging 39.5 ± 13.5 minutes.

Clinical Efficacy and Safety Outcomes

Despite the difference in operative time, both sequencing methods demonstrated high levels of effectiveness in clearing the common bile duct of stones.

Group B (LC-first) showed a common bile duct clearance rate of 95.7%, while Group A (ERCP-first) showed a rate of 88.2%. The study noted that these results were comparable, with a p-value of 0.163.

In terms of safety and complications, the study monitored the occurrence of post-ERCP pancreatitis. This complication occurred in four patients in the ERCP-first group and two patients in the LC-first group, a difference that was not statistically significant (p = 0.701).

Clinical Context and Conclusions

The research concludes that both the LC-first and ERCP-first approaches are feasible and highly effective strategies for treating cholecystocholedocholithiasis through single-stage management.

The primary distinction between the two methods lies in the operative duration, with the LC-first approach proving to be the more time-efficient option for the surgical team and the patient.

This finding contributes to the broader medical discussion regarding the management of common bile duct stones, where the shift toward single-stage treatments aims to reduce the burden on patients and the healthcare system compared to traditional two-stage treatments.
