The Center for Interventional Endoscopy at SEVG provides patients minimally invasive endoscopic procedures for the evaluation and management of various digestive disorders.

The physicians at SEVG work with a multidisciplinary team of physicians, including interventional radiologists, oncologists, surgeons, and pathologists to deliver high quality patient care.

The interventional endoscopists at SEVG have completed a dedicated training program beyond general gastroenterology/ hepatology training at leading therapeutic endoscopy training programs across the country, which sets SEVG apart from other local GI groups in metropolitan Phoenix.

In fact, SEVG receives referrals throughout Arizona for advanced endoscopic procedures.

Specialized Procedures Include:


Endoscopic Ultrasound/Fine Needle Aspiration (EUS/FNA)

EUS is a specialized endoscopic procedure that combines endoscopy with ultrasound technology for the examination of benign and malignant conditions of the upper and lower gastrointestinal tract, pancreas, gallbladder, bile duct, liver, and lymph nodes or lesions in the chest and abdomen. Evaluation of these internal organs previously required interventional radiology or surgery. Now, a specialized endoscope that has an ultrasound probe on its tip is able to take detailed, realtime ultrasound images and direct biopsies of abnormal lesions.


What are the indications?

  1. Cancer staging (evaluation of esophageal, gastric, pancreas, bile duct, rectal, and lung cancer)
  2. Sub-epithelial lesions of GI tract (lipomas, leiomyoma/ sarcoma, GIST, pancreatic rest, carcinoids, granular cells)
  3. Pancreaticobiliary disorders (pancreatic cysts, chronic pancreatitis, missed bile duct stones on conventional radiological imaging)
  4. Interventional EUS (Pain control by celiac plexus block for patients with pancreatic cancer, endoscopic mucosal resection of GI sub-epithelial lesions, localized injection of chemotherapy in tumors/fiducial seeds for radiation therapy)
  5. New indications are evolving as EUS provides a minimally invasive diagnostic and therapeutic intervention.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is an endoscopic procedure in which a specialized side-viewing upper endoscope, combined with X-Ray, allows for visualization and instrumentation of the bile duct and pancreatic duct. An interventional endoscopist can examine these structures for stones; strictures (blockage point); tumors of bile duct, pancreas duct, and ampulla; bile duct leaks after gallbladder surgery; or any pathology that impedes the flow of bile or pancreas juice into the intestine (duodenum). Although ERCP is a relatively safe and minimally invasive alternative to surgery for pancreaticobiliary disorders, complications may include bleeding, pancreatitis, perforation, infection, and sedation related complications. Therefore, only appropriately trained endoscopists should perform ERCP.
