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

GASTROENTEROLOGY
  • 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

GASTROENTEROLOGY
  • 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.

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.

GASTROENTEROLOGY

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.

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.

The "Artificial Intelligence" Endoscopy Suite

Colonoscopy is the most effective cancer prevention tool in medicine, but it relies on the human eye. At Liv Hospital, we augment human skill with AI.

  • CAD EYE™ Technology: As the camera moves through the colon, an Artificial Intelligence system scans every pixel in real-time. If it spots a polyp (which can be flat and hard to see), it highlights it on the screen with a blue box and alerts the doctor.
  • The Impact: This technology increases the “Adenoma Detection Rate” (ADR). Finding more polyps means preventing more cancers.
  • Comfort Sedation: We perform procedures under Deep Sedation (TIVA) administered by an anesthesiologist. You are not “awake but numb”; you are asleep. You wake up in the recovery room with no memory of the procedure and no pain.

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.

GASTROENTEROLOGY scaled LIV Hospital

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.

FREQUENTLY ASKED QUESTIONS

Is a colonoscopy painful?

No. At Liv Hospital, it is performed under Deep Sedation (Propofol). You will be asleep. You will not feel the tube, the air, or the biopsy. Most patients wake up asking, “Is it over already?”

The “bowel prep” (cleaning the colon) is the hardest part for most people.

  • Old Way: Drinking 4 liters of salty, bad-tasting liquid.

Liv Way: We use modern, low-volume prep solutions (often just 2 glasses split into two doses) combined with plenty of clear water or juice. It is much easier to tolerate.

Yes. This is called a “Double Balloon” or simply “Double Procedure.” It is very common. You receive one sedation, and we check both the stomach (upper) and colon (lower) in the same session. It takes about 30–40 minutes total.

  • IBS (Irritable Bowel Syndrome): A functional disorder. The gut looks normal on camera, but functions poorly (pain, diarrhea/constipation) due to sensitive nerves. It does not cause permanent damage.

IBD (Inflammatory Bowel Disease): A structural disease (Crohn’s/Colitis). The immune system attacks the gut, causing ulcers and bleeding. It requires strong medication to prevent damage.

No. Diagnostic endoscopy and most therapeutic procedures (like polyp removal or stone removal) are performed through natural body openings (mouth or anus). There are no external cuts and no external scars.
