Advanced Endoscopy

Our team of specialists focuses on advanced endoscopic procedures that utilize specialized endoscopy, endoscopic ultrasonography and fluoroscopic imaging (X-rays) to achieve success where standard endoscopy and even surgery may not be successful or feasible.

We perform nearly 1,000 endoscopic retrograde cholangiopancreatography (ERCP) every year and various other advanced therapeutic endoscopy.

Endoscopic management of advanced gastrointestinal malignancies

  • Treatment of esophageal cancer with cryotherapy and esophageal stenting
  • Using stents to treat obstructive gastric, duodenal and colonic cancers
  • Using advanced ERCP techniques to access and selectively stent hilar biliary strictures
  • Advanced EUS and ERCP technique to manage concurrent biliary and duodenal obstructions in pancreatic cancer
  • Palliate cancer-related pain symptoms by performing celiac plexus neurolysis through endoscopic ultrasound
  • Endoscopic management of precancerous gastrointestinal lesions and early cancers
  • Advanced ablative techniques for dysplastic (precancerous) Barrett’s like hybrid argon plasma coagulation and cryoablation
  • Percutaneous endoscopic gastrostomy tube placement (PEG tube)

Endoscopic & Colonoscopic polypectomy

A polypectomy is the removal of a polyp. Colon and Gastric polyps can be removed colonoscopy and endoscopy. The endoscopist may snip off a small polyp with a forceps or remove a larger polyp with a snare that burns through the base of the polyp.

Polypectomy of colonic polyps has been shown to reduce the risk of colon cancer development.

Polypectomy is a skill utilized by all endoscopists who perform endoscopy and colonoscopy. Mastery of polypectomy is difficult and requires significant experience.

How painful is polyp removal?

Patient should feel no pain. Patient may feel abdominal discomfort during procedure due to air insufflations.

How long does a polypectomy take?

A polypectomy lasts about 15 to 60 minutes depends on size of polyp and is an outpatient procedure, allowing patients to return home the same day. They should be back to a normal routine as soon as the next day.


Polypectomy is not without some risk of complications. Most complications are related either to post-polypectomy hemorrhage or perforation. Hemorrhage is the most common and is usually divided into immediate (less than 12 h post-procedure) and delayed (after 12 h post-procedure but up to 30 d).
