Dr. William Angelo Haniak

Dr. William Haniak diagnoses and treats a wide range of digestive system disorders, including:

Esophageal, Stomach & Upper GI Disorders

• Eosinophilic Esophagitis (EoE): A chronic immune system disease characterized by a buildup of eosinophils (a type of white blood cell) in the esophagus, causing inflammation, difficulty swallowing, food impaction, and chest pain.
• Esophageal Motility Disorders (e.g., Achalasia, Esophageal Spasms, Nutcracker Esophagus): Disorders affecting the coordinated muscle movements of the esophagus required for swallowing, leading to symptoms like dysphagia (difficulty swallowing), chest pain, and regurgitation.
• Gastritis (Inflammation of Stomach Lining) & Duodenitis: Inflammation of the stomach lining (gastritis) or the first part of the small intestine/duodenum (duodenitis), which can be acute or chronic and caused by various factors including infection, irritants, or autoimmune processes.

Liver, Gallbladder, Bile Duct & Pancreatic Disorders

• Autoimmune Liver Diseases (Autoimmune Hepatitis, PBC, PSC): Conditions where the body's immune system mistakenly attacks liver cells (Autoimmune Hepatitis), bile ducts within the liver (Primary Biliary Cholangitis), or larger bile ducts inside and outside the liver (Primary Sclerosing Cholangitis).
• 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.
• Non-Alcoholic Fatty Liver Disease (NAFLD) & Non-Alcoholic Steatohepatitis (NASH): A spectrum of conditions characterized by excessive fat accumulation in the liver not caused by alcohol. NASH involves liver inflammation and cell damage and can progress to cirrhosis.

Small & Large Intestine (Colorectal) Disorders

• 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.
• Diverticular Disease (Diverticulosis, Diverticulitis, Diverticular Bleeding): Diverticulosis is the presence of small pouches (diverticula) in the colon wall. Diverticulitis is inflammation or infection of these pouches. Diverticular bleeding can also occur.

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

• 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).
• 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.
• 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.
• Irritable Bowel Syndrome (IBS) Comprehensive Diagnosis & Management (including subtypes IBS-D, IBS-C, IBS-M): Multifaceted approach to managing IBS symptoms (abdominal pain, bloating, diarrhea, constipation, mixed pattern) including thorough exclusion of other conditions, dietary modifications (e.g., low FODMAP diet), lifestyle changes, stress management, and targeted medications.
• 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.
• Diagnosis & Management of Small Intestinal Bacterial Overgrowth (SIBO) & Intestinal Methanogen Overgrowth (IMO): Utilizing glucose or lactulose breath tests for diagnosis and providing targeted antibiotic/antimicrobial therapy, prokinetics, and dietary advice for SIBO and IMO.
• 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.

Note: This list provides a general overview. Specific procedures and treatments are determined after a thorough evaluation. Discuss with Dr. Haniak 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 British Columbia (CPSBC) and relevant gastroenterological care guidelines.

Are consultations and procedures like endoscopies with Dr. Haniak, a Gastroenterologist, covered by Medical Services Plan (MSP) in BC?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Haniak, 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 Medical Services Plan (MSP) in BC 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. Haniak's office, the hospital/clinic's financial services, or Medical Services Plan (MSP) beforehand.

Do I need a referral from my family doctor to see Dr. Haniak, 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. Haniak 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. Haniak 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. Haniak 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.

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

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Haniak 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's the difference between Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD)? Can Dr. Haniak diagnose and treat both?

Yes, a Gastroenterologist like Dr. Haniak can diagnose and treat both IBS and IBD, but they are very different conditions. IBD, which includes Crohn's disease and ulcerative colitis, is characterized by chronic inflammation and physical damage (like ulcers and strictures) to the digestive tract, visible during endoscopy and on biopsies. It's an autoimmune-related condition. IBS, on the other hand, is a functional gut disorder, meaning the GI tract doesn't work correctly, but there's no visible inflammation or damage on standard tests. IBS causes symptoms like abdominal pain, bloating, and altered bowel habits. While IBS can significantly impact quality of life, it doesn't cause the destructive inflammation seen in IBD. Diagnosis involves different criteria and investigations for each.
