Commentary Gallbladder adenocarcinoma is relatively uncommon, with <2 cases per 100,000 people in the United States. In the current case, the authors diagnosed this rare cancer in an elderly woman who experienced acute cholecystitis requiring EUS-guided gallbladder drainage by use of a LAMS. After introducing the upper endoscope through the LAMS, the authors were able to visualize frond-like masses and take a biopsy sample, examination of which later indicated gallbladder adenocarcinoma. They illustrate 2 relatively new enhanced imaging modes, which help in diagnosing early cancer. Texture and color enhancement imaging (TXI) combines 3 images into 1 image: 1 with dark areas brightened, 1 with color difference expansion, and 1 with enhanced texture sharpness. The “3-in-1” approach has been shown in randomized trials to increase the adenoma detection rate during colorectal cancer screening. Unique about TXI compared with NBI is that it preserves a somewhat normal appearance to the image while allowing enhanced lesion detection and characterization. Finally, although the authors showcase RDI in their last image, this technology is primarily designed to allow easier identification of bleeding points in a bloody field during endoscopic surgery rather than for diagnostic purposes.
