Surgeons often work in dimly lit areas to protect their eyes, but seeing clearly is still vital. A recent review looked at a technique called fluorescence-guided imaging using indocyanine green. This dye helps surgeons see key structures inside the body that are hard to spot with standard white light alone. The review examined data from elective and acute care settings where patients had symptomatic gallstone disease. The goal was to see if this special imaging could make operations safer and faster. The results showed that visualization of important biliary structures improved significantly. This means surgeons could identify critical areas more easily during the procedure. The review also noted potential reductions in complications, the need to convert to open surgery, and the time spent in the operating room. These benefits sound promising for patients facing these common operations. However, the review highlighted some important limitations. Dosing protocols varied between studies, and liver function can sometimes interfere with the imaging signal. The technology also requires specialized equipment that not all hospitals have. Because the evidence comes from a review rather than a single large trial, the exact benefits are not fully defined. Still, this radiation-free method extends the surgeon's visual capabilities without adding radiation exposure. It remains a tool that needs careful consideration before becoming standard practice everywhere.

Key Takeaway
Consider fluorescence-guided imaging with ICG as a potential adjunct, but recognize evidence remains preliminary.
This is a mini review that synthesizes evidence on fluorescence-guided imaging with indocyanine green (ICG) versus white light for symptomatic gallstone disease in elective and acute care settings. The authors report that ICG may improve visualization of key biliary structures and suggest potential reductions in complications, conversion to open surgery, and operative time. No pooled effect sizes, absolute numbers, or statistical measures are provided, as the evidence is qualitative.
The review notes several limitations, including heterogeneity in dosing protocols, interference from hepatic background fluorescence, and reliance on specialized imaging equipment. The authors acknowledge that the place of this technology in routine surgical practice is not established.
Practice relevance is described as a pragmatic, radiation-free modality that extends the surgeon's visual capabilities. However, the authors caution against overstating clinical benefits and the technology's role in routine practice. The review does not report specific study populations, sample sizes, or adverse events.

Fluorescence imaging may improve visibility and reduce risks during gallstone surgery, though equipment needs vary. View Original Abstract ↓
Laparoscopic cholecystectomy (LC) remains the standard treatment for symptomatic gallstone disease, yet bile duct injury persists as a serious and feared complication, predominantly caused by misidentification of biliary anatomy. Fluorescence-guided imaging with indocyanine green (ICG) has gained prominence as an adjunct to enhance real-time anatomical interpretation and strengthen intraoperative safety. This mini review synthesizes current evidence supporting fluorescent cholangiography in both elective and acute care settings, where inflammation, distorted anatomy, and urgent decision-making heighten surgical risk. The manuscript provides an updated overview of the technical foundations of ICG fluorescence, practical considerations for its administration, and its incorporation into modern surgical workflows. It compiles data demonstrating improved visualization of key biliary structures, and potential reductions in complications, conversion to open surgery, and operative time. The review also addresses persistent limitations, such as heterogeneity in dosing protocols, interference from hepatic background fluorescence, and reliance on specialized imaging equipment, that continue to impede universal standardization. Taken together, these findings position fluorescence imaging as a pragmatic, radiation-free modality that extends the surgeon's visual capabilities “beyond white light,” contributing to safer and more precise LC. Ongoing technological refinement and well-designed multicenter studies will be crucial to confirm its clinical benefits and define its place in routine surgical practice.
