JAG-Certified Endoscopy Treatment Overview
If you are looking for expert endoscopy, gastroscopy and colonoscopy in London, Mr Ali Haque provides specialist assessment and treatment for a range of digestive and gastrointestinal conditions. Endoscopy allows the inside of the digestive tract to be examined using a flexible camera, helping identify the cause of symptoms and, where appropriate, allowing treatment during the same procedure.
A gastroscopy examines the upper digestive system, including the oesophagus, stomach and duodenum. It may be recommended for symptoms such as persistent indigestion, reflux, difficulty swallowing, abdominal discomfort, nausea or suspected gastrointestinal bleeding. During the procedure, biopsies can also be taken when clinically required.
A colonoscopy examines the large bowel and rectum and can help investigate changes in bowel habits, abdominal pain, rectal bleeding and other lower gastrointestinal symptoms. It can also be used for colorectal cancer screening and may allow polyps to be removed or tissue samples to be taken during the examination.

Dual Expertise: Surgery and Endoscopy
Mr. Haque brings together advanced endoscopic expertise and surgical experience, giving him a comprehensive understanding of gastrointestinal conditions and their treatment. Rather than simply identifying a problem, he can assess the wider range of management options — from minimally invasive endoscopic treatment to more advanced surgical procedures. This combined expertise can be particularly valuable when cases are complex or treatment decisions require careful consideration.
Advanced Technical Skills
Mr. Haque has received specialised training at leading tertiary centres and has developed extensive experience in both diagnostic and therapeutic endoscopy. His technical expertise, combined with sound clinical judgement, allows him to manage challenging anatomy and complex conditions while aiming to provide effective treatment during the same procedure whenever appropriate.
Compassionate Patient Care
Undergoing an endoscopy can understandably cause anxiety for many patients. Mr. Haque places strong emphasis on clear communication, taking time to explain the procedure beforehand and ensuring appropriate sedation and comfort measures are considered. His calm and supportive approach helps patients feel informed, reassured, and confident throughout their care.
Multidisciplinary Collaboration
Complex gastrointestinal conditions often benefit from input from several medical specialists. Mr. Haque works closely with gastroenterologists, surgeons, radiologists, oncologists, and pathologists to ensure that patients receive coordinated and comprehensive care. This collaborative approach is especially important when findings require further investigation or when multiple treatment options need to be considered.
State-of-the-Art Equipment
Diagnostic accuracy and therapeutic success depend on technology. Mr. Haque utilises modern endoscopic equipment with high-definition imaging, advanced optical systems, and specialised therapeutic devices ensuring optimal visualisation and intervention capability.
Upper GI Endoscopy (Gastroscopy): Diagnostic and Therapeutic Excellence
Upper GI endoscopy, commonly known as gastroscopy, is a procedure used to examine the oesophagus, stomach, and duodenum using a thin, flexible camera passed gently through the mouth. The procedure usually takes around 5–15 minutes and allows the doctor to directly assess the upper digestive tract and identify a range of conditions.
Common Reasons for an Upper GI Endoscopy:
- Persistent heartburn, reflux, or GERD symptoms
- Difficulty swallowing or a sensation of food sticking
- Unexplained weight loss or reduced appetite
- Ongoing nausea or vomiting
- Upper abdominal pain or discomfort
- Suspected gastritis or peptic ulcer disease
- Investigation of gastrointestinal bleeding
- Monitoring of Barrett’s oesophagus or suspicious changes
- Assessment before anti-reflux surgery
- Evaluation and treatment of strictures or swallowing problems
- Persistent heartburn, reflux, or GERD symptoms
What to Expect: You’ll receive mild sedation to ensure comfort, then Mr. Haque will gently pass the endoscope through your mouth. You’ll feel no pain—the sedation ensures relaxation and minimal discomfort. High-definition imaging allows precise visualisation. If biopsies are needed or therapeutic intervention required (such as bleeding control or polyp removal), these are performed during the same procedure. Most patients recover within 1-2 hours.
Lower GI Endoscopy (Colonoscopy): Prevention and Diagnosis
Colonoscopy is a detailed examination of the colon and rectum using a flexible camera inserted through the anus. It plays an important role in colorectal cancer screening, investigating lower GI symptoms, and monitoring inflammatory bowel conditions. With modern equipment and appropriate sedation, the procedure is generally safe, well tolerated, and can provide both diagnostic and therapeutic benefits.
Common Reasons for Colonoscopy
- Screening for colorectal cancer and prevention through polyp removal
- Investigation of persistent diarrhoea, constipation, or changes in bowel habits
- Evaluation of unexplained lower abdominal pain or rectal bleeding
- Assessment and monitoring of inflammatory bowel disease, including Crohn’s disease and ulcerative colitis
- Detection and removal of polyps or other precancerous abnormalities
- Collection of tissue samples (biopsies) when required
- Treatment of strictures and selected other bowel conditions
- Assessment of patients with a significant family history of colorectal cancer
Polyp Removal: Prevention in Practice
Many colorectal cancers begin as benign polyps that can gradually develop into cancerous growths. During colonoscopy, identified polyps can often be removed before they have the opportunity to progress. This makes colonoscopy an important tool not only for detecting disease but also for preventing colorectal cancer.
What to Expect
Good bowel preparation, usually with a prescribed laxative solution, is essential for a clear examination. Appropriate sedation may be provided to improve comfort and reduce awareness of the procedure. The colon will be carefully examined, and any suitable polyps may be removed. Biopsies can also be taken when necessary. Following the examination, the findings and recommended next steps will be explained during recovery.
The Benefits of Professional JAG-Certified Endoscopy
Accurate Diagnosis
High-definition endoscopic imaging allows detailed examination of the bowel and can help identify the underlying cause of symptoms. Where appropriate, biopsies and other findings can provide further diagnostic information.
Therapeutic Treatment
One of the major advantages of endoscopy is that certain problems can be treated during the same procedure. This may include removing polyps, controlling bleeding, taking biopsies, or dilating narrowed areas, potentially avoiding the need for a separate procedure.
Cancer Prevention
Colorectal cancer screening can identify precancerous polyps at an early stage. Removing these lesions can reduce the risk of future cancer development, making screening an important part of colorectal cancer prevention.
Minimal Invasiveness
Compared with traditional surgery, endoscopy is a minimally invasive procedure. It generally involves no external incision and often allows patients to return home on the same day, depending on the procedure and individual circumstances.
Peace of Mind
A normal examination can provide reassurance when no significant abnormality is found. If an abnormality is detected, the results can help guide appropriate follow-up, treatment, or further investigation.
Cost-Effective Care
By combining diagnosis and, where appropriate, treatment in a single procedure, endoscopy can help reduce the need for repeated investigations and may provide a more efficient approach to managing gastrointestinal symptoms.
Understanding Your Endoscopy Results
Normal Findings
A normal colonoscopy means that no significant abnormality was identified during the examination. Depending on the reason for the procedure and your individual risk factors, your doctor may advise that another examination is not required for several years.
Polyps Identified and Removed
If polyps are found and removed, they will usually be sent for laboratory examination. The recommended timing of future surveillance colonoscopy will depend on the number, size, type, and other characteristics of the polyps.
Inflammation or Infection
If inflammation or signs of infection are identified, tissue samples may be taken to help determine the cause. Your doctor can then discuss appropriate treatment, which may include medication, dietary changes, or additional investigations.
Source of Bleeding Identified
If the examination identifies a cause of gastrointestinal bleeding, treatment may sometimes be performed during the procedure. Further management and follow-up will depend on the underlying cause and the findings.
Dysplasia or Early Cancer
If abnormal cellular changes (dysplasia) or early cancer are detected, your doctor will explain the available management options. Depending on the findings, this may include endoscopic treatment, close surveillance, or referral for specialist surgical assessment.
