Dr. Andrew Szilagyi diagnoses and treats a wide range of digestive system disorders, including:

Liver, Gallbladder, Bile Duct & Pancreatic Disorders

• Pancreatitis (Acute Recurrent & Chronic): Inflammation of the pancreas that can be sudden and severe (acute), recurrent, or long-lasting (chronic), causing significant abdominal pain and digestive enzyme deficiencies.
• Alcohol-Related Liver Disease (ARLD): Liver damage caused by excessive alcohol consumption, ranging from fatty liver and alcoholic hepatitis to advanced cirrhosis.

Small & Large Intestine (Colorectal) Disorders

• 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.
• 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.

Functional Gastrointestinal & Motility Disorders

• Pelvic Floor Dysfunction & Anorectal Disorders (e.g., Dyssynergic Defecation): Inability to correctly relax and coordinate pelvic floor muscles to facilitate a normal bowel movement, often requiring specialized testing like anorectal manometry and biofeedback therapy.
• 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).

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

• Endoscopic Dilation of Gastrointestinal Strictures (Esophageal, Pyloric, Colonic): Procedure to stretch narrowed areas (strictures) in the esophagus (e.g., due to reflux, EoE), stomach outlet (pylorus), small intestine, or colon using balloons or Savary-Gilliard dilators passed through an endoscope.
• 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.
• Gastrointestinal Motility Disorder Evaluation & Management Coordination: Initial evaluation of symptoms suggestive of GI motility disorders (e.g., gastroparesis, achalasia, chronic intestinal pseudo-obstruction), with coordination for specialized testing like esophageal manometry, antroduodenal manometry, wireless motility capsule, or gastric emptying studies, and subsequent management strategies.
• 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.
• 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.
• Flexible Sigmoidoscopy with Biopsy: Examination of the lower part of the colon (sigmoid colon and rectum) using a flexible sigmoidoscope, often for evaluation of rectal bleeding, diarrhea, or as part of some screening protocols.
• 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.

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

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

Medically necessary consultations with a licensed Gastroenterologist like Dr. Szilagyi, 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. Szilagyi'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. Szilagyi, 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. Szilagyi 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.

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

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. Szilagyi or the anesthesia provider beforehand. Because of the sedation, you will need to have someone accompany you to drive you home after the procedure.

How does Dr. Szilagyi approach treating functional GI disorders like IBS or functional dyspepsia?

Treating functional GI disorders like Irritable Bowel Syndrome (IBS) or functional dyspepsia often involves a multi-faceted approach tailored by Dr. Szilagyi to your specific symptoms and triggers. Since these conditions don't have a structural cause seen on tests, management focuses on symptom relief and improving quality of life. This may include dietary modifications (like identifying trigger foods or trying a low FODMAP diet for IBS), lifestyle adjustments (stress management, regular exercise), fiber supplements, over-the-counter remedies, and prescription medications. Medications can target specific symptoms like pain (antispasmodics), diarrhea (anti-diarrheals), constipation (laxatives), or abnormal gut-brain interaction (neuromodulators in low doses). He will work with you to find the most effective combination of strategies.

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. Szilagyi'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.

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. Szilagyi. 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. Szilagyi 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.
