Dr. Moses Ernest Fung

Dr. Moses Fung diagnoses and treats a wide range of digestive system disorders, including:

Inflammatory Bowel Disease (IBD) Focus

• Microscopic Colitis (often considered alongside IBD for chronic diarrhea): Though distinct from classic IBD, it's an inflammatory condition of the colon diagnosed by biopsy, causing chronic watery diarrhea.
• Indeterminate Colitis & IBD-Unclassified (IBD-U): Cases of IBD, particularly early in the disease course, where it is difficult to definitively distinguish between Crohn's disease and ulcerative colitis based on clinical, endoscopic, and histological features.
• Ulcerative Colitis (Proctitis, Left-sided Colitis, Pancolitis): A chronic inflammatory condition that causes inflammation and ulcers primarily in the lining of the large intestine (colon and rectum), typically presenting with bloody diarrhea, urgency, and abdominal pain.

Functional Gastrointestinal & Motility Disorders

• Rumination Syndrome: A condition in which people repeatedly and unintentionally spit up (regurgitate) undigested or partially digested food from the stomach, rechew it, and then reswallow it or spit it out.
• Gastroparesis (Delayed Gastric Emptying): A condition that affects the normal spontaneous movement of the muscles (motility) in your stomach, preventing proper and timely emptying of stomach contents, leading to nausea, vomiting, and fullness.

Small & Large Intestine (Colorectal) Disorders

• Microscopic Colitis (Lymphocytic & Collagenous Colitis): Inflammation of the colon that is only visible under a microscope when biopsies are examined, a common cause of chronic watery diarrhea, particularly in older adults.
• Colorectal Polyps (Adenomatous, Serrated) & Colorectal Cancer Prevention/Screening: Abnormal growths in the colon or rectum that can be precursors to colorectal cancer. Screening (e.g., colonoscopy, FIT) is vital for removal of polyps, prevention, and early detection of cancer.

This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Moses Fung.

• Helicobacter pylori (H. pylori) Testing & Eradication Therapy: Diagnosis of H. pylori infection using breath tests, stool tests, or endoscopic biopsies, and providing appropriate antibiotic regimens for eradication to treat ulcers and gastritis.
• Biofeedback Therapy Coordination for Pelvic Floor Dysfunction & Fecal Incontinence: Evaluation for defecatory disorders and fecal incontinence, with coordination of biofeedback therapy and other interventions to improve pelvic floor muscle function.
• Upper Endoscopy (EGD - Esophagogastroduodenoscopy) with Biopsy & Interventions: Diagnostic and therapeutic procedure to examine the esophagus, stomach, and duodenum using a flexible tube with a camera. Allows for targeted biopsies, polyp removal (polypectomy), dilation of strictures, control of bleeding (hemostasis), and foreign body removal.
• Screening & Prevention Strategies for Gastrointestinal Cancers: Risk assessment and counseling on screening for colorectal cancer, esophageal cancer (in Barrett's esophagus), gastric cancer, and liver cancer (in cirrhosis), including FIT testing and colonoscopy recommendations.
• Endoscopic Hemostasis for Acute & Chronic GI Bleeding: Various endoscopic techniques (e.g., injection therapy, thermal coagulation/APC, mechanical clips, hemostatic sprays) used to stop acute or recurrent bleeding from ulcers, varices, angiodysplasias, or tumors in the GI tract.
• Endoscopic Ultrasound (EUS) with Fine Needle Aspiration/Biopsy (FNA/FNB): Procedure combining endoscopy with ultrasound to obtain high-resolution images and tissue samples (FNA/FNB) of the digestive tract wall, surrounding organs (pancreas, liver, adrenal glands, gallbladder), and lymph nodes for staging cancers or diagnosing lesions.
• ERCP (Endoscopic Retrograde Cholangiopancreatography) - Diagnostic & Therapeutic: Specialized procedure combining upper endoscopy and X-rays to diagnose and treat problems of the bile and pancreatic ducts, such as gallstone removal from bile duct, stent placement for strictures or leaks, and sphincterotomy.

Note: This list provides a general overview. Specific procedures and treatments are determined after a thorough evaluation. Discuss with Dr. Fung for care relevant to your specific condition.

All medical and surgical services (if applicable) are provided in accordance with the standards of practice set by the College of Physicians and Surgeons of Alberta (CPSA) and relevant gastroenterological care guidelines. Contact the clinic or your referring physician regarding new patient intake and referral processes.

The clinic is fully accessible, with wheelchair access to accommodate all patients, and paid parking options are conveniently located nearby for those arriving by car.

Are consultations and procedures like endoscopies with Dr. Fung, a Gastroenterologist, covered by Alberta Health Care Insurance Plan (AHCIP) in AB?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Fung, as well as most diagnostic procedures (e.g., endoscopies for investigating symptoms, biopsies for medical reasons) and treatments for provincially insured digestive conditions (e.g., IBD, celiac disease, screening colonoscopies as per provincial guidelines, liver disease management), are generally covered by Alberta Health Care Insurance Plan (AHCIP) in AB when a referral from a family doctor or another specialist is in place. Procedures considered purely for screening outside of guidelines, or for non-medical reasons, and some advanced technologies or specific drug therapies might have different coverage. It's crucial to discuss coverage specifics for any proposed treatment or procedure with Dr. Fung's office, the hospital/clinic's financial services, or Alberta Health Care Insurance Plan (AHCIP) beforehand.

Do I need a referral from my family doctor to see Dr. Fung, a Gastroenterologist?

Yes, in nearly all cases, a referral from your family physician or another specialist (such as an internist or surgeon) is required to schedule an appointment with a Gastroenterologist like Dr. Fung for services covered by the provincial health plan. Gastroenterological issues often require initial assessment and preliminary investigations by your primary care provider. The referral ensures that a specialist consultation is appropriate, helps with prioritizing appointments, and facilitates coordinated care, including the transfer of relevant medical information.

How does a Gastroenterologist like Dr. Fung approach the management of Inflammatory Bowel Disease (IBD)?

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Fung is a highly individualized and long-term process. The primary goals are to induce and then maintain remission (control inflammation), alleviate symptoms, prevent complications, and improve the patient's overall quality of life. Treatment strategies often involve a combination of medications, which can include aminosalicylates (5-ASAs), corticosteroids (for acute flare-ups), immunomodulators (e.g., azathioprine, methotrexate), and increasingly, biologic therapies or small molecule drugs that target specific inflammatory pathways. Regular monitoring through clinical assessment, blood tests, stool tests (like fecal calprotectin), and endoscopic procedures is crucial to track disease activity and adjust treatment as needed. Nutritional counseling and lifestyle advice are also integral parts of comprehensive IBD care.

Are there significant risks associated with procedures like gastroscopy or colonoscopy?

Gastroscopy (upper endoscopy) and colonoscopy are generally very safe procedures, especially when performed by an experienced Gastroenterologist like Dr. Fung. Complications are uncommon. Potential risks can include bleeding, particularly if polyps are removed or biopsies are taken; perforation (a tear in the wall of the digestive tract); infection (rare); or adverse reactions to the sedative medication used. Before your procedure, Dr. Fung will thoroughly discuss the specific potential risks and benefits based on your individual health and the reason for the procedure, allowing you to make an informed decision.

Will I be asleep for my endoscopy or colonoscopy with Dr. Fung?

For most endoscopic procedures like upper endoscopy (gastroscopy) and colonoscopy, patients are typically given sedation to help them relax and be comfortable. This is often called 'conscious sedation' or 'moderate sedation,' meaning you'll be drowsy and may not remember much of the procedure, but you won't be under general anesthesia (completely unconscious with a breathing tube). The specific type and level of sedation can vary and will be discussed with you by Dr. Fung or the anesthesia provider beforehand. Because of the sedation, you will need to have someone accompany you to drive you home after the procedure.
