For this gastroenterologist and his colleagues, it can mean treating cancer sooner
(January 2012) Harry Aslanian, MD, enjoyed playing the early Atari video games in his youth. This may have contributed to the excellent hand-eye coordination that now make him a sought-after expert in complex endoscopy procedures.
A gastroenterologist who uses specialized endoscopy to diagnose and treat disorders of the pancreas and bile ducts, Dr. Aslanian was drawn to the field because he liked the immediate visual representation of disease and the technical challenge of endoscopy.
Focusing largely on endoscopic ultrasound, he uses an endoscope (a flexible lighted tube with a camera) with an ultrasound probe built into its tip to examine places that are difficult to reach. "The pancreas is right near the stomach and it's a notoriously difficult area to get detailed pictures of. By looking from inside the stomach we get the most accurate imaging," he says.
Dr. Aslanian performs a procedure.
If he sees an abnormality, Dr. Aslanian is able to pass a tiny needle through the endoscope and perform a biopsy of the pancreas. The cells are analyzed immediately in the procedure room, by cytologists, experts in analyzing the microscopic appearance of cells. This often allows Dr. Aslanian to provide a diagnosis before the patient goes home. If a cancer is identified, the patient is referred to a team of highly skilled specialists.
More and more, Dr. Aslanian, Priya Jamidar, MD, and their colleagues in the Yale Interventional Endoscopy Program are able to detect and treat early cancers and other conditions during the same procedure. They immediately remove precancerous polyps and superficial tumors of the colon, esophagus, stomach or small bowel through the endoscope.
In addition to endoscopic ultrasound and colonsocopy, Dr. Aslanian performs a procedure called endoscopic retrograde cholangio-pancreatography (ERCP), which combines endoscopy, a contrast dye and fluoroscopic X-rays to image and treat disorders of the bile and pancreas ducts, including blockages due to stones or tumors.
Technological advances in imaging continue to improve Dr. Aslanian's ability to detect abnormalities. Using probe-based confocal microscopy, he can pass a very small microscope through the endoscope or the tip of a needle and see individual cells inside the intestine, bile duct or pancreas.
"There's nothing else like it because it's so miniaturized and gives you views down to the cellular level in real time," he says.
Meanwhile, he and his colleagues are working on new endoscopic ablative treatments that can destroy precancerous tissues of the esophagus, bile duct and pancreas. "There's a continual evolution of tools and techniques, and it's an exciting time to be performing interventional endoscopy," Dr. Aslanian says.
