Comparing Laparoscopic Ultrasound and Fluorescence Cholangiography with Indocyanine Green During Difficult Laparoscopic Gallbladder Surgery

What this Trial Is About

Researchers are evaluating two imaging methods, laparoscopic ultrasound LUS and fluorescence cholangiography with indocyanine green ICG, to identify biliary anatomy during technically challenging laparoscopic gallbladder removal surgery. This multicenter, prospective, interventional clinical trial aims to compare the success of these techniques in detecting critical junctions of bile ducts, which is important for patient safety during surgery. Participants will undergo both imaging tests during their gallbladder surgery in a set order first LUS, then fluorescence cholangiography before the key surgical dissection. This allows direct comparison of the two methods within the same procedure. The study focuses on patients who have anticipated surgical difficulty due to conditions like acute cholecystitis, prior abdominal surgeries, or obesity. During the study, researchers will monitor how clearly each imaging method identifies important bile duct junctions, how long it takes to visualize these structures, total surgery time, and any complications during or after surgery. The study also involves tracking patient outcomes intraoperatively and postoperatively to assess safety and effectiveness. Participation begins with surgery and includes follow-up for these measures.
