At Cooley Dickinson Hospital, patients benefit from a dedicated Endoscopy Center and an expert nursing staff. Each week we perform over a hundred endoscopy procedures that help detect and screen for colon cancer, diagnose gastrointestinal problems, treat ulcers, find and remove polyps, as well as treat and diagnose other diseases and disorders. Many of the procedures in our Endoscopy Center require sedation, and we have a skilled anesthesia team to assist with procedures. Commonly performed procedures include:

  • Upper G.I. endoscopy
  • Colonoscopy
  • Polypectomies
  • Flexible sigmoidoscopy
  • Endoscopic Retrograde Cholangiopancreatography (ERCP) – endoscopic imaging of the liver, pancreas, bile ducts and gallbladder
  • Bronchoscopy

The center features four procedure rooms and twelve admission and recovery bays that provide privacy and comfort for patients. Our technology and equipment help gastroenterologists and pulmonologists perform procedures accurately and efficiently.
