What each procedure is, when it is used, and what it involves.
01
Pancreas and bile ducts
Complex pancreato-biliary endoscopy is a core part of Dr. Roy Chaudhuri’s work.
ERCP
Endoscopic retrograde cholangiopancreatography. An endoscope passed through the mouth reaches the opening of the bile and pancreatic ducts, so that stones can be removed, narrowings widened and stents placed without open surgery.
Endoscopic ultrasound (EUS)
An endoscope with a small ultrasound probe at its tip gives detailed images of the pancreas, the bile ducts and the wall of the gut from the inside.
Therapeutic EUS
EUS can also guide treatment: taking biopsies with a fine needle, draining fluid collections around the pancreas into the stomach (cystogastrostomy), and draining a blocked bile duct (choledochoduodenostomy, CDS).
02
Third-space endoscopy and resection
Treatment carried out within the wall of the gut, through the endoscope.
POEM
Peroral endoscopic myotomy. The tight muscle at the lower end of the food pipe is divided from the inside, with no cuts on the outside. Used for achalasia and related swallowing disorders.
Full-thickness resection (FTRD)
A device fitted to the endoscope removes selected growths from the wall of the gut in one piece, including some that cannot be removed by standard techniques.
Complex therapeutic endoscopy
Endoscopic treatment for problems that might otherwise need an operation, planned case by case.
03
GI bleeding
Finding the source and stopping it.
Endoscopic control of bleeding
The source of bleeding in the food pipe, stomach or bowel is located and treated through the endoscope.
04
Tests of gut function
When the structure looks normal but the gut is not working as it should.
Manometry
A thin pressure-sensing tube measures how the muscles of the gut squeeze and relax. Used to investigate swallowing difficulty and other motility disorders.
05
Diagnostic endoscopy
The starting point for many digestive symptoms.
Upper GI endoscopy
A thin, flexible camera examines the food pipe, the stomach and the first part of the small intestine.
Colonoscopy
A flexible camera examines the large intestine, for symptoms such as bleeding or a lasting change in bowel habit.
Before a procedure
What you will be told in advance
Preparation differs from one procedure to another, so the exact instructions are given when yours is scheduled.
