Dr. Davide Maggio 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.
• 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.

Esophageal, Stomach & Upper GI Disorders

• Dysphagia (Difficulty Swallowing) & Odynophagia (Painful Swallowing): Symptoms requiring investigation to determine underlying causes, which can range from structural abnormalities and motility disorders to inflammatory conditions or tumors.
• Peptic Ulcer Disease (Gastric, Duodenal, H. pylori-related, NSAID-induced): Open sores that develop on the inside lining of the stomach (gastric ulcer) and the upper portion of the small intestine (duodenal ulcer), commonly caused by H. pylori infection or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Functional Gastrointestinal & Motility Disorders

• 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).
• 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.
• 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.

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

• 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.
• 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.
• 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).
• 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.
• 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.
• 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.
• Management of Functional Dyspepsia & Functional Abdominal Pain Syndrome: Diagnosis and management of chronic upper abdominal pain or discomfort (dyspepsia) or generalized abdominal pain without an identifiable structural cause, often involving lifestyle, dietary, and neuromodulator therapies.

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

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

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

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. Maggio. 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. Maggio 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. Maggio?

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