Abstract

Introduction

Choledocholithiasis is most often managed in a two-procedure pathway including endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). In contrast, a single-stage, surgery-first approach consisting of LC, cholangiogram, and laparoscopic common bile duct exploration (LCBDE) is associated with reduced hospital stays and equivalent morbidity. Despite this, nationwide referral patterns heavily favor ERCP, obscuring those undergoing ERCP with obstructions amenable to simple intraoperative interventions. We hypothesized that most patients had endoscopic findings consistent with simple sludge or small-to-medium stones, which could have been cleared by basic LCBDE maneuvers.

Methods

We retrospectively reviewed 294 patients > 18 years old who underwent preoperative ERCP for the management of suspected choledocholithiasis. Exclusion criteria included: failed ERCP, cholangitis, prior cholecystectomy, patient refusal of surgery, or medical conditions precluding surgical candidacy. Stone size was categorized as small (0–4 mm), medium (5–7 mm), and large (≥ 8 mm).

Results

At the time of ERCP, 37 (20.1%) patients had sludge only, 96 (52.2%) had stones only, 42 (22.8%) had sludge and stones, and 9 (4.8%) had no stones. Of the 138 patients with any stones, 37 (26.8%) had small stones, 41 (29.7%) medium, 43 (31.2%) large, and 17 (12.3%) had uncharacterizable stones. Overall, 74.3% of patients had findings of sludge, stones (0–7 mm), or negative ERCP.

Conclusion

The majority of patients who underwent preoperative ERCP for suspected choledocholithiasis had findings that are amenable to simple intraoperative interventions. In fact, over a quarter of the patients had a negative ERCP, sludge, or small stones which would likely be cleared by flushing/glucagon precluding any further instrumentation. While large stones may require more advanced techniques, this represents a small percentage of patients. Surgery-first management for suspected choledocholithiasis can offer an efficient alternative for the majority of patients.
