Dr. Benjamin Thériault

Dr. Benjamin Thériault diagnoses and treats a wide range of digestive system disorders, including:

Liver, Gallbladder, Bile Duct & Pancreatic Disorders

• Chronic Viral Hepatitis (Hepatitis B, C, D): Long-term viral infections that cause inflammation and damage to the liver, potentially leading to cirrhosis, liver failure, or liver cancer if untreated.
• Pancreatic Cysts, Tumors & Pancreatic Insufficiency (Evaluation & Co-management): Evaluation of fluid-filled sacs (cysts) or growths (tumors) on or in the pancreas, and management of exocrine pancreatic insufficiency (EPI) where the pancreas doesn't produce enough digestive enzymes.
• Gallstone Disease (Cholelithiasis), Cholecystitis & Choledocholithiasis: Formation of hardened deposits (gallstones) in the gallbladder. Cholecystitis is gallbladder inflammation. Choledocholithiasis refers to gallstones in the common bile duct.

Functional Gastrointestinal & Motility Disorders

• Cyclic Vomiting Syndrome: A disorder characterized by recurrent, stereotypical episodes of intense nausea and vomiting lasting for hours or days, with symptom-free intervals in between.
• 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.
• 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.

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.
• Celiac Disease & Gluten Sensitivity: Celiac disease is an autoimmune disorder triggered by gluten ingestion, damaging the small intestine. Non-celiac gluten sensitivity involves GI symptoms related to gluten without the autoimmune damage.

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

• Colonoscopy (Screening, Diagnostic, Surveillance) & Polypectomy: Comprehensive examination of the entire colon (large intestine) using a colonoscope to detect and remove precancerous polyps, screen for and diagnose colorectal cancer, evaluate symptoms, and diagnose other colonic conditions like colitis or diverticular disease.
• Personalized Nutritional Assessment & Medical Dietary Therapy for GI Conditions: Evaluation of nutritional status and provision of evidence-based dietary advice and medical nutrition therapy tailored to specific gastrointestinal disorders like IBD, IBS, celiac disease, eosinophilic esophagitis, gastroparesis, or food intolerances, often in collaboration with registered dietitians.
• 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.
• 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.
• Second Opinion Consultations for Complex Digestive Diseases: Providing expert second opinions on challenging or rare gastrointestinal diagnoses, unclear test results, and proposed complex treatment plans, including for IBD, liver disease, and pancreatic disorders.
• Comprehensive Gastroenterology Consultation & Digestive Health Assessment: In-depth assessment of digestive system disorders, including detailed review of medical history, family history, lifestyle factors, physical examination, symptom analysis, and development of a personalized diagnostic and treatment strategy.
• Capsule Endoscopy (Small Bowel & Colon): Non-invasive procedure where the patient swallows a vitamin-pill sized camera that takes pictures of the small intestine (for obscure GI bleeding, Crohn's disease) or colon (as an alternative to colonoscopy in select cases).

Medically necessary consultations with a licensed Gastroenterologist like Dr. Thériault, 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. Thériault'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. Thériault, 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. Thériault 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 exactly does a Gastroenterologist like Dr. Thériault specialize in?

A Gastroenterologist, often called a GI specialist, is a medical doctor who has undergone extensive specialized training beyond medical school and internal medicine residency to diagnose, treat, and manage diseases of the entire digestive or gastrointestinal (GI) system. This includes the esophagus, stomach, small intestine, colon (large intestine), rectum, anus, as well as associated organs like the liver, gallbladder, bile ducts, and pancreas. He is a Gastroenterologist specializing in the comprehensive medical and procedural management of digestive system disorders. Dr. Thériault is skilled in performing endoscopic procedures (like gastroscopy and colonoscopy) for both diagnosis and treatment, interpreting complex diagnostic tests, and developing comprehensive management plans for a wide variety of acute and chronic digestive health issues.

What are common reasons someone would be referred to a Gastroenterologist like Dr. {provider_name_doctor_last}?

Referral to a Gastroenterologist like Dr. Dr. Thériault 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.

What are some common procedures a Gastroenterologist like Dr. Thériault typically performs?

Gastroenterologists like Dr. Thériault 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, He 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.
