Dr. Chad Evaschesen 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
- Gastroesophageal Reflux Disease (GERD) / Acid Reflux / Heartburn: Chronic condition where stomach acid frequently flows back into the esophagus, causing heartburn, regurgitation, chest pain, and potential complications like esophagitis.
- 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.
Small & Large Intestine (Colorectal) Disorders
- Irritable Bowel Syndrome (IBS) - All Subtypes (IBS-D, IBS-C, IBS-M, IBS-U): A common functional gastrointestinal disorder affecting the large intestine, causing symptoms like cramping, abdominal pain, bloating, gas, and changes in bowel habits (diarrhea, constipation, or mixed).
- 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.
- Ischemic Colitis: Inflammation and injury of the large intestine that results from inadequate blood flow.
This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Chad Evaschesen.
- 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.
- 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.
- 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 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.
- Management of Common & Chronic Digestive Symptoms: Investigating and treating common but potentially disruptive digestive symptoms such as heartburn, acid reflux, bloating, abdominal pain, cramping, excessive gas, constipation, diarrhea, difficulty swallowing (dysphagia), and unexplained weight loss.
- ERCP (Endoscopic Retrograde Cholangiopancreatography) - Diagnostic & Therapeutic: Specialized procedure combining upper endoscopy and X-rays to diagnose and treat problems of the bile and pancreatic ducts, such as gallstone removal from bile duct, stent placement for strictures or leaks, and sphincterotomy.
- 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.
Note: This list provides a general overview. Specific procedures and treatments are determined after a thorough evaluation. Discuss with Dr. Evaschesen for care relevant to your specific condition.

- Are consultations and procedures like endoscopies with Dr. Evaschesen, a Gastroenterologist, covered by Medical Services Plan (MSP) in BC?
- Medically necessary consultations with a licensed Gastroenterologist like Dr. Evaschesen, 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. Evaschesen'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. Evaschesen, 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. Evaschesen 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. Evaschesen?
- 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. Evaschesen or the anesthesia provider beforehand. Because of the sedation, you will need to have someone accompany you to drive you home after the procedure.
- What's the difference between Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD)? Can Dr. Evaschesen diagnose and treat both?
- Yes, a Gastroenterologist like Dr. Evaschesen 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.
- 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. Evaschesen'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.
