Diagnostic and
Endoscopic Services
At Gastrocare London, we offer a comprehensive range of diagnostic and advanced endoscopic procedures to investigate and treat digestive, liver, and pancreatic problems. Below are the procedures we perform with easy-to-understand explanations and links to trusted leaflets.
Gastroscopy (Upper GI Endoscopy)
A thin, flexible tube with a camera is passed through the mouth to examine the oesophagus, stomach, and upper part of the small intestine. It helps diagnose acid reflux, ulcers, or cancer.
Detects causes of heartburn, pain, or swallowing problems
Identifies ulcers, inflammation, or early cancer
Safe and minimally invasive with quick recovery
Colonoscopy
A long, flexible camera is passed through the rectum to examine the colon (large bowel). Used to investigate bleeding, changes in bowel habit, polyps, or screen for bowel cancer.
Detects and removes polyps before they become cancerous
Identifies ulcers, inflammation, or early cancer
Safe and minimally invasive with quick recovery
Flexible Sigmoidoscopy
A shorter version of colonoscopy that examines the lower part of the colon. It is often used to investigate bleeding, pain, or changes in bowel movements.
Quickly examines the rectum and lower colon for problems
Detects causes of bleeding, pain, or bowel habit changes
Can remove small polyps during the same procedure

Capsule Endoscopy (Small Bowel & Colon)
A small camera in a capsule is swallowed to take thousands of images as it passes naturally through the digestive tract. This helps identify causes of anaemia, bleeding, or Crohn’s disease in areas not reached by traditional scopes.
Non-invasive and painless — no tubes or sedation needed
Reaches parts of the small bowel not accessible by standard scopes
Helps diagnose bleeding, anaemia, and Crohn’s disease
ERCP (Endoscopic Retrograde CholangioPancreatography)
A specialised endoscopy combined with X-rays to examine and treat conditions of the bile ducts and pancreas - including stone removal, bile duct stenting, and treatment of strictures.
Diagnoses and treats bile duct and pancreatic disorders
Enables stone removal and stent placement to relieve blockages
Minimally invasive alternative to major surgery
EUS (Endoscopic Ultrasound)
An endoscope with a built-in ultrasound probe is used to closely examine the pancreas, bile ducts, and lymph nodes. It can also be used to take biopsies or drain fluid collections.
Provides highly detailed images of the pancreas and bile ducts
Allows safe biopsy of tissue for accurate diagnosis
Can guide drainage of fluid collections without surgery
SpyGlass Cholangioscopy
An ultra-thin endoscope passed through the ERCP scope to directly visualise the bile ducts. Useful for diagnosing difficult strictures or treating complex stones.
Directly visualises the bile ducts for precise diagnosis
Helps distinguish between benign and malignant strictures
Enables targeted treatment of complex or difficult stones

Polypectomy
Removal of abnormal tissue (polyps) from the colon during colonoscopy. This helps prevent bowel cancer by removing pre-cancerous growths early.
Safely removes pre-cancerous growths during colonoscopy
Prevents bowel cancer by treating polyps early
Quick procedure with no need for separate surgery
Enteral Stenting
Stents can be placed to open narrowed areas in the digestive tract (e.g., bile duct, duodenum, colon) that may be causing blockages due to cancer or strictures.
Relieves blockages in the digestive tract to restore normal flow
Minimally invasive alternative to major surgery
Provides rapid symptom relief and improves quality of life
Additional Diagnostics & Testing
FIT Test
Simple stool test to detect microscopic gastrointestinal bleeding.
Calprotectin
Detects inflammation in the intestines, helpful for IBD diagnosis and monitoring.
Fibroscan
Check liver function and stiffness.
MRCP, CT & MRI
Detailed scans to examine bile ducts, pancreas, and other abdominal organs.
