Dr. Thomas Krahn

Dr. Thomas Krahn diagnoses and treats a wide range of digestive system disorders, including:

Esophageal, Stomach & Upper GI Disorders

• 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.
• Hiatal Hernia & Paraesophageal Hernia: Condition where part of the stomach pushes upward through an opening (hiatus) in the diaphragm into the chest, potentially contributing to GERD and other symptoms.

Liver, Gallbladder, Bile Duct & Pancreatic Disorders

• 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.
• 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.
• Alcohol-Related Liver Disease (ARLD): Liver damage caused by excessive alcohol consumption, ranging from fatty liver and alcoholic hepatitis to advanced cirrhosis.

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.
• Microscopic Colitis (often considered alongside IBD for chronic diarrhea): Though distinct from classic IBD, it's an inflammatory condition of the colon diagnosed by biopsy, causing chronic watery diarrhea.

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

• 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.
• Enteroscopy (e.g., Double-Balloon, Single-Balloon, Spiral Enteroscopy): Advanced endoscopic techniques allowing deep visualization, biopsy, and therapy within the small intestine, beyond the reach of standard endoscopes, for conditions like obscure bleeding or small bowel tumors.
• 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.
• 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.
• 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).
• Interpretation & Correlation of Advanced Digestive Health Diagnostic Tests: Expert analysis and clinical correlation of results from endoscopies, biopsies, imaging studies (CT, MRI, MRCP, ultrasound), breath tests (e.g., for H. pylori, SIBO, lactose intolerance), stool tests (e.g., calprotectin, FIT), motility studies, and genetic testing for GI conditions.
• 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.

Note: This list provides a general overview. Specific procedures and treatments are determined after a thorough evaluation. Discuss with Dr. Krahn 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 Alberta (CPSA) and relevant gastroenterological care guidelines. Contact the clinic or your referring physician regarding new patient intake and referral processes.

Are consultations and procedures like endoscopies with Dr. Krahn, a Gastroenterologist, covered by Alberta Health Care Insurance Plan (AHCIP) in AB?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Krahn, 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 Alberta Health Care Insurance Plan (AHCIP) in AB 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. Krahn's office, the hospital/clinic's financial services, or Alberta Health Care Insurance Plan (AHCIP) beforehand.

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

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

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Krahn 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 an integral part of comprehensive IBD care.

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

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