Gastroenterology

Gastroenterology is an important branch of medicine that studies the gastrointestinal system and digestive health. This field diagnoses and treats diseases affecting the digestive system, which extends from the mouth to the anus. The system includes the esophagus, stomach, small intestine, and large intestine. Additionally, the liver, gallbladder, and pancreas are also areas of focus in gastroenterology.

Gastroenterologists treat many digestive disorders such as heartburn (reflux), gastritis, and ulcers. Intestinal diseases like irritable bowel syndrome, Crohn’s disease, and ulcerative colitis are also included in this specialty.

Celiac disease, liver diseases, and gallstones are other conditions treated by gastroenterologists. Pancreatitis and digestive system cancers are important health issues managed by these specialists as well.

To diagnose and treat these diseases, gastroenterologists use various procedures such as endoscopy, colonoscopy, and biopsy. When necessary, surgical interventions for bile duct issues and other problems are carried out under their guidance. The diagnosis and treatment of specific conditions like stomach pain and gallstones are managed by gastroenterology experts. Swallowing difficulties related to esophageal problems also fall within this department’s scope.

The main goal of the gastroenterology department is to accurately diagnose and treat digestive system disorders.

Within this scope, services are provided in the following areas:

• Gastroesophageal Reflux Disease (GERD)

• Peptic Ulcer Disease

• Inflammatory Bowel Diseases (IBD)

• Liver Diseases

• Gallbladder and Biliary Tract Diseases

• Pancreatic Diseases

• Colorectal Diseases

• Functional Bowel Disorders

• Endoscopic Procedures

• Food Intolerances and Allergies

• Gastrointestinal Bleeding

Gastroenterology focuses on the digestive system. This field examines several organs, including:

• Esophagus

• Stomach

• Duodenum

• Small intestines

• Large intestines

• Bile ducts

• Pancreatic duct

Gastroenterology diagnoses and treats health problems related to these organs. In this process, various advanced diagnostic and treatment methods play a vital role. Here are some commonly used basic procedures in gastroenterology:

Examining the internal structure of the digestive system is important. Different imaging techniques are used to make an accurate diagnosis and plan treatment.

Endoscopy: Provides direct visualization of the inner surface of the digestive system through a thin, flexible tube with a camera at the tip. Different types of endoscopy focus on different parts of the digestive system:

• Upper Endoscopy (Gastroscopy): Examines the esophagus, stomach, and duodenum in detail. It is important for diagnosing upper digestive system problems such as difficulty swallowing, stomach pain, and acid reflux.

• Colonoscopy: Visualizes the inner surface of the large intestine and plays a critical role in diagnosing bowel diseases and detecting/removing polyps.

• ERCP (Endoscopic Retrograde Cholangiopancreatography): Used to image the bile ducts and pancreatic duct and intervene in problems in these areas. It is important for diagnosing and treating gallstones and strictures in the bile ducts.

• Enteroscopy: A method used to examine deeper parts of the small intestine.

• Capsule Endoscopy: Non-invasive imaging of the small intestine using a small camera capsule swallowed by the patient.

• Biopsy: Samples taken from suspicious tissues during endoscopy for microscopic examination, vital for diagnosing cancer and other bowel diseases.

Imaging Tests: Non-invasive methods to obtain general and detailed images of the digestive system:

• Abdominal X-ray: Shows a general view of the digestive system, helping to detect obstructions or perforations.

• CT Scan (Computed Tomography): Provides cross-sectional images of digestive organs and surrounding tissues, offering important information about tumors, inflammations, and other health issues.

• Magnetic Resonance Imaging (MRI): Provides clear and detailed images of digestive organs and surrounding tissues, especially useful for assessing liver, bile ducts, and pancreatic diseases.

• Ultrasound: Produces real-time images of abdominal organs and blood flow, commonly used for evaluating the liver, gallstones, and pancreas.

• Liver Function Tests: Assess how well the liver is working and help diagnose and monitor liver diseases.

• Stool Tests: Used to detect infections, inflammation, or bleeding in the gastrointestinal system.

• Lactose Intolerance Test: A test used to diagnose lactose intolerance.

• Hydrogen Breath Test: Used to detect bacterial overgrowth in the small intestine (SIBO) or sugar malabsorption.

Gastroenterology is a dynamic medical specialty focused on improving the health of the digestive system. Following diagnostic procedures, gastroenterologists aim to enhance patients' quality of life through various innovative treatment methods. These treatments range from minimally invasive endoscopic procedures to complex surgical interventions. Here are commonly applied and specialized treatment methods in gastroenterology:

Endoscopic treatments involve reaching the inner parts of the digestive system using specialized instruments. These methods do not require surgical incisions or only involve minimal incisions.

These approaches allow patients to heal faster, experience less pain, and reduce hospital stay durations:

• Polypectomy: Protective Intervention Against Colon Cancer: This procedure involves the surgical removal of polyps detected in the colon during colonoscopy. Different techniques (hot polypectomy, cold polypectomy, etc.) may be applied depending on the type and size of the polyp. This simple but effective intervention reduces the risk of polyps turning into cancer and plays an important role in preventing colon cancer.

• Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD): Promising Treatments for Early-Stage Cancers: Early-stage digestive system cancers, especially stomach, esophagus, and colon cancers, can be removed endoscopically without large incisions. EMR is used to remove small tumors in the mucosal layer, while ESD allows removal of larger and more complex lesions extending into the submucosal layer in one piece. These methods are preferred because they preserve organs and improve patients’ quality of life.

• Variceal Ligation and Sclerotherapy: Effective Solutions for Esophageal Varices: Varices, enlarged veins in the esophagus due to conditions like liver cirrhosis, pose a serious bleeding risk. Endoscopic methods control bleeding and prevent recurrence. Variceal ligation ties varices with special rubber bands; sclerotherapy injects medications that constrict veins. These treatments are critical in managing life-threatening bleeding.

• Stent Placement: Easy Solution for Obstructions: Stents are placed to open narrowed or blocked bile ducts or esophagus, allowing passage of fluids or food. Stents can be metal or plastic tubes. This method greatly improves quality of life for patients unsuitable for surgery or needing palliative care, especially relieving jaundice from bile duct obstruction and aiding feeding in patients with swallowing difficulties.

• Percutaneous Endoscopic Gastrostomy (PEG) and Jejunostomy (PEJ): Reliable Methods for Nutritional Support: These methods insert feeding tubes directly into the stomach (PEG) or small intestine (PEJ) for patients who cannot take adequate nutrition orally. Suitable for patients with neurological disorders or swallowing difficulties, as well as those requiring long-term postoperative enteral nutrition, these methods offer safe and comfortable nutritional support.

In gastroenterology, advanced endoscopic or surgical interventions may be required in certain cases:

Endoscopic Full-Thickness Resection (EFTR): This procedure involves the endoscopic removal of lesions that involve all layers of the digestive tract wall. It is used for deeper and more complex lesions compared to ESD.

Endoscopic Ultrasound (EUS) Guided Interventions: EUS provides detailed images of the digestive tract wall and surrounding organs. It allows for needle biopsy procedures known as EUS-FNA/FNB. Treatments such as cyst drainage and drug injection are also possible with this method.

Surgical Treatments: Surgery may be necessary in cases such as advanced cancers or complicated inflammatory bowel diseases. Surgery is also indicated when endoscopic methods are insufficient. Minimally invasive techniques like laparoscopic and robotic surgery are increasingly used alongside traditional open surgery.

Treatment methods in gastroenterology are continuously evolving and becoming more personalized. The most appropriate treatment is selected based on the patient’s condition, disease stage, and overall health.
