Outcomes following balloon sphincteroplasty as an adjunct to laparoscopic common bile duct exploration

Laparoscopic common bile duct exploration (LCBDE) at the time of cholecystectomy is an efficient pathway for management of choledocholithiasis. Performing this safely under one anesthetic offers advantages over a two-step process with cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP). Despite the proven efficacy of LCBDE, endoscopy continues to be predominantly utilized. Simplifying the intervention may drive LCBDE adoption. To this end, we refined a stepwise intraoperative pathway that utilizes over the wire balloon catheters to dilate the Sphincter of Oddi to facilitate stone passage into the duodenum. To determine the efficacy during the initial adoption phase on a general surgery service, we reviewed our experience with LCBDE balloon sphincteroplasty as part of this pathway.

We retrospectively reviewed the records of patients who underwent LCBDE with balloon sphincteroplasty at a single tertiary care center over a three-year period. Preoperative demographics, imaging/laboratory results, intra and postoperative outcomes were reviewed.

Choledocholithiasis was managed with transcystic balloon sphincteroplasty during LCBDE in 28 cases over a three-year period. The cohort included 16 women and 12 men with a mean age of 47 years (range = 19-89). Operative indications included cholecystitis (n = 11, 39%), choledocholithiasis (n = 13, 47%), cholelithiasis (n = 2, 7%), and gallstone pancreatitis (n = 2, 7%). The stones were successfully cleared by the balloon sphincteroplasty technique in 75% of the cases. The average fluoroscopy time during LCBDE was 338 s (± 214). The average operating room time was 173 min (± 35). Mean length of stay was 58 h (± 46). There were no intra- or postoperative complications.

Wire ready cholangiography followed by balloon sphincteroplasty with saline/contrast flush is a simple and safe way to clear the common bile duct. This technique is a gateway for further expansion and adoption of LCBDE.
