Gastroenterology

Gastroenterology covers the digestive system. It focuses on diagnosing, treating, and managing conditions of the stomach, intestines, liver, and pancreas.

Discover the modern approach to digestive system health! In the video below, Assoc. Prof. Dr. Çağdaş Erdoğan explains how Liv Hospital combines advanced diagnostic technologies with patient comfort to provide life-saving treatments for complex gastrointestinal conditions.

In this comprehensive overview, we explore the innovative procedures, tailored treatments, and patient-centered protocols that define our state-of-the-art gastroenterology department.

Overview and Definition

The Science of Inner Health

The digestive system is the engine of the human body. It fuels every cell, regulates our immune system, and even influences our mood—scientists now call the gut our "Second Brain." When this complex system falters, it affects not just your stomach, but your entire quality of life.

At Liv Hospital, the Department of Gastroenterology and Hepatology is more than just an endoscopy clinic. We are a comprehensive "Digestive Disease Center" dedicated to the diagnosis, treatment, and prevention of diseases affecting the gastrointestinal tract and liver. We have moved beyond the era of simply diagnosing problems; today, we fix them. Using advanced Interventional Gastroenterology techniques, we can remove early-stage tumors, clear bile duct stones, and treat swallowing disorders entirely through an endoscope—without a single incision on your skin.

Whether you are seeking a routine cancer screening or a solution for a complex liver condition, our team combines academic expertise with the latest technology (like AI-assisted colonoscopy) to provide care that is safe, precise, and surprisingly comfortable.

What is Gastroenterology?

Gastroenterology is the branch of medicine focused on the digestive system and its disorders. It covers a massive territory, from the mouth to the anus, including the accessory organs that aid digestion.

The Digestive Tract

• Esophagus: The swallowing tube (Reflux, Achalasia).
• Stomach: The mixing chamber (Ulcers, Gastritis, Cancer).
• Small Intestine: Where nutrients are absorbed (Celiac Disease, Crohn's).
• Colon and Rectum: Waste processing (Polyps, Colitis, Cancer).

The Accessory Organs

• Liver (Hepatology): The body's chemical factory (Hepatitis, Fatty Liver, Cirrhosis).
• Pancreas: Produces enzymes and insulin (Pancreatitis, Cysts).
• Gallbladder & Bile Ducts: Stores and transports bile (Stones, Blockages).

At Liv Hospital, our specialists are often sub-specialized. You might see a Hepatologist for your liver and an Interventional Endoscopist for your polyp removal. This ensures you are treated by a master of that specific organ.

Symptoms and Risk Factors

Interventional Gastroenterology

The most significant advancement in our field is the ability to perform "surgery" from the inside. By passing specialized tools through the endoscope, we can treat conditions that previously required major open surgery.

ERCP

• The Problem: A gallstone slips out of the gallbladder and blocks the main bile duct, causing jaundice and severe infection (Cholangitis). Or, a tumor blocks the duct.
• The Solution: We guide a scope down the throat into the small intestine. We locate the tiny opening of the bile duct (papilla), cut the muscle slightly, and use a basket to pull the stone out or place a stent to open the blockage.
• The Benefit: No abdominal incision, immediate relief of jaundice, and often discharged the next day.

EUS (Endoscopic Ultrasound)

• The Tech: A standard endoscope only sees the surface of the stomach wall. An EUS scope has a mini-ultrasound probe at the tip.
• The Vision: It allows us to see through the stomach wall to examine the pancreas, lymph nodes, and liver adjacent to it.
• The Biopsy (FNA/FNB): If we see a suspicious mass in the pancreas, we can extend a needle from the scope to take a biopsy instantly. It is the gold standard for diagnosing Pancreatic Cancer.

ESD and EMR

• The Revolution: In the past, a large polyp or early-stage stomach cancer meant removing part of the stomach surgically.
• ESD (Endoscopic Submucosal Dissection): We inject fluid under the tumor to lift it, then use a tiny electric knife to "peel" the tumor off the muscle layer in one piece.
• The Result: The organ is saved. You keep your stomach or colon intact, and the cancer is cured.

POEM

• For Achalasia: A condition where the muscle at the bottom of the esophagus is too tight, preventing food from entering the stomach.
• The Procedure: We tunnel through the lining of the esophagus and cut the tight muscle from the inside.

Diagnosis and Evaluation

How GI Conditions Are Diagnosed at Liv Hospital

Doctors use several tools to diagnose digestive conditions. Gastroscopy (for the upper GI tract) and colonoscopy (for the lower GI tract) let doctors see inside and take tissue samples. Capsule endoscopy, where you swallow a small camera, helps view the small intestine. Breath tests can find food intolerances or bacterial overgrowth.

Treatment and Management

Specialized Clinics for Chronic Conditions

Digestive diseases are often chronic. We offer dedicated clinics to manage them long-term.

IBD Center (Inflammatory Bowel Disease)

For patients with Crohn’s Disease and Ulcerative Colitis.

• Goal: Mucosal Healing (no ulcers visible).
• Therapies: We use the latest Biologic drugs (Anti-TNF, Anti-Integrin) and small molecules (JAK inhibitors) to induce and maintain remission.

Motility and Reflux Center

For heartburn (GERD), constipation, and swallowing issues.

• pH-Metry: Measuring acid levels in the esophagus over 24 hours to confirm reflux.
• Manometry: Measuring the pressure and coordination of the esophageal muscles. Crucial before any reflux surgery.

Pancreatic Cyst Clinic

Incidental cysts are often found on MRI scans. Most are benign, but some are pre-cancerous (IPMN). We use EUS and cyst fluid analysis to determine which ones need surgery and which can be safely watched.

Recovery and Prevention

Why Choose Liv Hospital for Gastroenterology?

1. Safety First: Endoscopes are complex instruments that are hard to clean. We use hospital-grade Automated Endoscope Reprocessors (AER) that wash and sterilize scopes at high temperatures. We track every scope electronically to ensure 100% sterility for every patient.
2. The "One-Stop" Concept: In many countries, you wait weeks for a consult, then months for a scope. At Liv Hospital, we can often arrange your consultation, blood work, and endoscopy/colonoscopy within 48 hours.
3. Cancer Screening Packages: For international patients, we offer "Gastro-Check" packages that combine Gastroscopy and Colonoscopy in a single sedation session, saving you time and cost.
4. Multidisciplinary Tumor Board: If cancer is found, your case is immediately discussed by the GI Tumor Council (Surgeon, Oncologist, Radiologist, Gastroenterologist) to plan the best treatment.
