Gastroenterology and Hepatology at Double Check

Gastroenterology is a vast subsection of internal medicine, and covers disorders of the oesophagus, the gastrointestinal tract, and the large organs in the abdominal cavity. Double Check® offers an extensive spectrum of diagnostic and treatment services in the area of gastroenterology, including:

What is Gastroscopy?
Gastroscopy is a highly effective method for diagnosing non-specific upper abdominal pain. It involves an endoscope being placed in the mouth and moved down the oesophagus and into the stomach. This helps, for example to identify and prescribe treatment for bacterial infection (helicobacter pylori), gastric and duodenal ulcers, oesophageal and gastric tumours or gluten intolerance.

What is Colonoscopy?
Colonoscopy (examination of the entire large intestine, the rectum, and the anus using a flexible viewing tube) is an important part of preventative health examinations. It is also indicated for resolving the causes of non-specific abdominal pains, irregular bowel movements, blood in the stool, endoscopic polyps monitoring, removal of polyps and other precancerous lesions and the diagnosis or progress monitoring of chronic inflammatory bowel diseases (Crohn’s disease/ulcerative colitis).

What is Proctoscopy?
A proctoscopy (examination of the lowest part of the rectum and anal canal using a viewing tube) may be recommended to diagnose or classify the severity of haemorrhoids and prescribe therapy. It is also a reliable and safe method for excluding anal carcinoma (malicious tumours in the anal canal) or anal fissures (tiny tears in the anal mucous membrane).

What is Endoscopy?
An endoscopy enables us to look inside the body, using a specially-illuminated optical instrument (an endoscope) to examine the interior of a hollow organ or body cavity. Gastrointestinal endoscopy (or stomach endoscopy) enables us to see the inside lining of your digestive tract and to enable the diagnosis and treatment of gastrointestinal diseases.

Ultrasound of the abdominal organs and vessels:
For many complaints, an ultrasound of the abdominal organs is a safe and non-invasive diagnostic tool. When performed properly by Double Check’s® experts, it is also a very effective method to confirm or exclude various internal illnesses.
