Endoscopy Services

Endoscopy is a procedure that allows doctors to look inside your body through the use of an endoscope. Scopes have a small camera attached to the end of a long, thin tube. The physician uses the scope to see inside an organ. 

If you would like to view and download your specific instructions for pre-procedure preparation, please visit our patient resources page. 
Types of endoscopic procedures performed at Lawrence General include:
  • colonoscopy (colon area),
  • endoscopic retrograde cholangiopancreatography (liver, gallbladder, bile ducts and pancreas) 
  • endoscopic ultrasound (digestive and lung areas) 
  • gastroscopy (stomach area) 
The Lawrence General Hospital endoscopy team, led by gastrointestinal medical director Maurice Cohen, MD, will provide you with the highest level of comfort, privacy and convenience, before, during and after examinations. 

Our process allows a patient to move smoothly and quickly through their procedure. Our nursing staff, which includes certified gastrointestinal nurses, is highly trained and dedicated to patient care.

Endoscopic procedures should be schedule through your primary care physician. Please speak with your physician about scheduling an appointment.
