- Power-washing, traditionally used for cleaning surfaces, is now explored as a method for collecting cytology specimens from the stomach during endoscopy procedures for gastric cancer screening or surveillance.
- Led by Dr. Charles J. Lightdale and colleagues from Columbia University Irving Medical Center, a novel high-pressure liquid spray delivered via the ERBEJET flexible probe was tested in a proof-of-concept study.
- Standard biopsy collection methods, such as systematic random biopsies, can be laborious, time-consuming, costly, and prone to sampling error due to the large surface area of the stomach.
- The power-washing procedure involves spraying the gastric mucosa systematically with a high-pressure liquid spray, dislodging cells, which are then suctioned and collected for cytology examination. This method is performed using sweeping and painting motions.
