Dr. Myriam Dumas-Campagna

Dr. Myriam Dumas-Campagna diagnoses and treats a wide range of digestive system disorders, including:

Inflammatory Bowel Disease (IBD) Focus

• 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.
• Crohn's Disease (Ileal, Colonic, Ileocolonic, Perianal): A chronic inflammatory condition that can affect any part of the digestive tract from mouth to anus, causing transmural (full-thickness) inflammation, pain, diarrhea, weight loss, and potential complications like strictures or fistulas.

Small & Large Intestine (Colorectal) Disorders

• Ischemic Colitis: Inflammation and injury of the large intestine that results from inadequate blood flow.
• 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.
• Small Intestinal Bacterial Overgrowth (SIBO) & Intestinal Methanogen Overgrowth (IMO): An abnormal increase in the bacterial population in the small intestine, or an overgrowth of methane-producing archaea, leading to symptoms like bloating, gas, abdominal pain, and altered bowel habits.

Functional Gastrointestinal & Motility Disorders

• Functional Dyspepsia & Epigastric Pain Syndrome: Persistent or recurrent pain or discomfort centered in the upper abdomen (dyspepsia) or specifically in the epigastric region, without an identifiable structural cause after investigation.
• Chronic Idiopathic Constipation (CIC) & Opioid-Induced Constipation (OIC): Persistent constipation that does not have an identifiable underlying cause (CIC) or is a side effect of opioid medications (OIC).
• 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.

This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Myriam Dumas-Campagna.

• Endoscopic Mucosal Resection (EMR) & Endoscopic Submucosal Dissection (ESD) for Early GI Cancers & Large Polyps: Advanced endoscopic techniques for the removal of large, flat, or early-stage cancerous or precancerous lesions from the lining of the GI tract, offering a less invasive alternative to surgery in select cases.
• Placement & Management of Percutaneous Endoscopic Gastrostomy (PEG) & Jejunostomy (PEJ) Tubes: Endoscopic procedure to place a feeding tube directly into the stomach (PEG) or jejunum (PEJ) for long-term enteral nutritional support, including tube care and replacement.
• Placement of Esophageal, Enteral & Colonic Stents: Endoscopic placement of self-expanding metal or plastic stents to relieve obstruction caused by tumors or benign strictures in the esophagus, small intestine, or colon.
• Radiofrequency Ablation (RFA) for Barrett's Esophagus & Other Conditions: Endoscopic procedure using radiofrequency energy to ablate dysplastic Barrett's esophagus or treat other conditions like gastric antral vascular ectasia (GAVE).
• Argon Plasma Coagulation (APC) & Other Thermal Therapies: Endoscopic technique using argon gas and electrical current or other thermal modalities to treat bleeding lesions (e.g., angiodysplasias, GAVE), ablate abnormal tissue (e.g., Barrett's esophagus, radiation proctitis), or reduce tumor ingrowth.
• Esophageal, Gastric & Colonic Variceal Banding, Sclerotherapy & Glue Injection: Endoscopic treatment to prevent or manage bleeding from esophageal, gastric, or ectopic varices, typically in patients with portal hypertension due to liver cirrhosis.
• Foreign Body Removal from the Upper & Lower GI Tract: Endoscopic retrieval of ingested or inserted foreign objects lodged in the esophagus, stomach, duodenum, or colon, often requiring specialized instruments.

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

Are consultations and procedures like endoscopies with Dr. Dumas-Campagna, a Therapeutic Endoscopist (Gastroenterologist), covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations with a licensed Therapeutic Endoscopist (Gastroenterologist) like Dr. Dumas-Campagna, 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 Régie de l'assurance maladie du Québec (RAMQ) in QC 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. Dumas-Campagna's office, the hospital/clinic's financial services, or Régie de l'assurance maladie du Québec (RAMQ) beforehand.

Do I need a referral from my family doctor to see Dr. Dumas-Campagna, a Therapeutic Endoscopist (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 Therapeutic Endoscopist (Gastroenterologist) like Dr. Dumas-Campagna 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.

What are some common procedures a Therapeutic Endoscopist (Gastroenterologist) like Dr. Dumas-Campagna typically performs?

Gastroenterologists like Dr. Dumas-Campagna are highly skilled in performing a range of endoscopic procedures. The most common are upper endoscopy (also called EGD or gastroscopy) to examine the esophagus, stomach, and duodenum, and colonoscopy to visualize the entire colon. During these procedures, She can take biopsies (small tissue samples for analysis), remove polyps (which can prevent colon cancer), dilate narrowed areas (strictures), control bleeding, and place feeding tubes. Other procedures may include flexible sigmoidoscopy (examining the lower colon), capsule endoscopy (swallowing a tiny camera to see the small intestine), and more specialized interventions like ERCP or EUS depending on their training and practice focus. Many also specialize in managing specific areas like hepatology (liver disease) or IBD.

What are common reasons someone would be referred to a Gastroenterologist like Dr. Dumas-Campagna?

Referral to a Gastroenterologist like Dr. Dumas-Campagna is common for various reasons, including: persistent heartburn or acid reflux (GERD); difficulty or pain when swallowing; unexplained abdominal pain or bloating; chronic nausea or vomiting; significant changes in bowel habits (e.g., chronic diarrhea, severe constipation); blood in the stool or rectal bleeding; iron deficiency anemia with no obvious cause; suspected or diagnosed Inflammatory Bowel Disease (Crohn's disease, ulcerative colitis); Irritable Bowel Syndrome (IBS) not responding to initial management; celiac disease; abnormal liver function tests or suspected liver disease (like hepatitis or fatty liver); pancreatitis; or for screening and surveillance colonoscopies to prevent colorectal cancer, especially if there's a family history or personal history of polyps.

How does a Therapeutic Endoscopist (Gastroenterologist) like Dr. Dumas-Campagna approach the management of Inflammatory Bowel Disease (IBD)?

The management of IBD (Crohn's disease and ulcerative colitis) by a Therapeutic Endoscopist (Gastroenterologist) like Dr. Dumas-Campagna 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.

What is generally involved in preparing for a colonoscopy procedure?

Preparing for a colonoscopy is a critical step to ensure the procedure is effective and safe. Dr. Dumas-Campagna's office will provide very specific instructions, which must be followed closely. Typically, preparation involves dietary changes for a few days beforehand (e.g., low-residue diet), followed by a clear liquid diet for the 24 hours prior to the exam. The most important part is the bowel cleansing process, which involves drinking a prescribed laxative solution designed to completely empty and clean your colon. This usually starts the evening before and may continue the morning of the procedure. You'll also need to arrange for transportation home, as sedation is commonly used.
