Precision Vision for Inner Health

The digestive tract is a dark, winding tunnel hidden deep within the body. For centuries, doctors could only guess what was happening inside based on symptoms. Today, we don’t guess; we see.

At Liv Hospital, Gastroenterology Diagnosis is defined by two words: Precision and Comfort. We utilize the world’s most advanced optical technology—including Artificial Intelligence (AI) enhanced cameras and capsule robots—to inspect every millimeter of the digestive lining. We can detect a precancerous polyp the size of a grain of rice, measure the stiffness of your liver without a needle, and diagnose acid reflux with a wireless chip.

Crucially, we understand that procedures like colonoscopy can be anxiety-inducing. That is why our “Comfort Endoscopy” protocol ensures that every diagnostic procedure is performed under Deep Sedation (TIVA) administered by an anesthesiologist. You sleep peacefully, feel no pain or embarrassment, and wake up only when the work is done.

The "Gold Standard" Endoscopy Suite

Endoscopy is the cornerstone of digestive health. It involves using a flexible, high-definition tube (scope) to examine the gut. At Liv Hospital, we use Fujifilm ELUXEO™ systems with Blue Light Imaging (BLI) and Linked Color Imaging (LCI), which enhance the contrast of blood vessels to make tumors “glow” against healthy tissue.

Gastroscopy (Upper GI Endoscopy)

Gastroenterology
  • What it sees: The Esophagus, Stomach, and Duodenum (start of small intestine).
  • Why we do it: To diagnose ulcers, gastritis, H. pylori infection, Celiac disease, and Esophageal Cancer.
  • The Experience: It takes 10–15 minutes. We spray the throat with numbing medicine and administer sedation. You will not gag or feel the tube.
  • Rapid Urease Test (CLO): During the procedure, if we see redness, we take a tiny biopsy and test it immediately for H. pylori bacteria. We often have the result before you wake up.

Colonoscopy (Lower GI Endoscopy)

  • What it sees: The entire Colon (Large Intestine) and Rectum.
  • Why we do it: It is the only test that prevents cancer. We look for polyps (fleshy growths) that can turn into cancer over 5–10 years. If we find them, we remove them instantly (Polypectomy).
  • The AI Advantage (CAD EYE™): The human eye can miss flat or small polyps hidden behind folds. Our AI system scans the video feed in real-time. If it detects a polyp, a blue box flashes on the screen and a sound alerts the doctor. This increases our detection rate significantly.
  • Carbon Dioxide Insufflation: Instead of using regular air to inflate the bowel (which causes bloating and cramps later), we use CO2. The body absorbs CO2 150 times faster than air, meaning you wake up with almost no gas pain.

Capsule Endoscopy

There is a “blind spot” between the stomach and colon: the 6-meter long Small Intestine. Standard scopes cannot reach here.

  • The Tech: You swallow a pill-sized camera (about the size of a large vitamin).
  • The Journey: As it travels through your system naturally over 8 hours, it takes 50,000+ photos and transmits them wirelessly to a recorder on your belt.
  • The Diagnosis: It helps find obscure bleeding sources (AVMs), Crohn’s Disease ulcers in the small bowel, or small tumors. The camera is disposable and passes naturally in the stool.

Advanced Interventional Diagnostics (EUS & ERCP)

Sometimes, we need to look deeper than the surface lining or fix a problem in the ducts.

FibroScan (Transient Elastography)

  • The Procedure: A probe is placed on your right rib cage. It sends a shear wave (vibration) through the liver.
  • What it Measures:
    • Stiffness (kPa): Tells us how much scarring (fibrosis) is present. (e.g., F0 is healthy, F4 is Cirrhosis).
    • CAP Score (Fat): Tells us how much fat is in the liver (Steatosis).
  • The Benefit: It takes 5 minutes, is completely painless, and requires no sedation. It is the gold standard for monitoring Fatty Liver Disease and Hepatitis.

Liver Biopsy (Ultrasound-Guided)

While rare now, biopsy is still needed for complex cases (like Autoimmune Hepatitis or unexplained liver enzyme spikes).

  • Safety: We use real-time ultrasound to guide the needle, avoiding blood vessels and the gallbladder. It is performed under local anesthesia and light sedation.

Functional Testing: How Does it Work?

Sometimes the anatomy looks normal (no tumor), but the organ doesn’t move correctly.

High-Resolution Esophageal Manometry

  • For: Difficulty swallowing (Dysphagia) or chest pain not caused by the heart.
  • The Test: A thin catheter with 36 pressure sensors is passed through the nose into the esophagus. You swallow sips of water.
  • The Map: The computer creates a colorful “pressure map” (Clouse Plot) showing how your muscles squeeze. It is the only way to diagnose Achalasia (where the lower valve fails to open).

Wireless pH Monitoring (Bravo Capsule)

  • For: Severe heartburn (GERD) where surgery is being considered, or “silent reflux” (chronic cough).
  • The Test: During a gastroscopy, we clip a tiny chip (size of a gel cap) to the bottom of the esophagus.
  • The Recording: It measures acid levels for 48–96 hours while you eat, sleep, and live normally.
  • The Result: It proves definitively if acid is the cause of your symptoms. The capsule falls off naturally after a few days.

Hydrogen Breath Tests

  • For: Bloating, gas, and diarrhea.
  • The Concept: Bacteria in the gut ferment sugars, producing hydrogen or methane gas, which is exhaled in your breath.
  • Types:
    • Lactose Intolerance: Can you digest dairy?
    • Fructose Intolerance: Can you digest fruit sugar?
    • SIBO (Small Intestinal Bacterial Overgrowth): Do you have too many bacteria in your small bowel?

The "Gastro-Check" Lab

Diagnostic accuracy depends on the laboratory behind the scope.

  • Fecal Calprotectin: A stool test that measures inflammation. It helps distinguish between IBS (no inflammation) and IBD (high inflammation) without needing an immediate colonoscopy.
  • Helicobacter Stool Antigen: A non-invasive way to check if your antibiotic treatment successfully killed the H. pylori bacteria.
  • Genetic Testing: For patients with a family history of colon cancer, we test for Lynch Syndrome markers (MSI) on polyp samples.

Preparation and Safety: The Liv Standard

We know that for many patients, the preparation is worse than the procedure. We have optimized it.

  • Split-Dose Prep: We divide the laxative drink into two smaller doses (night before and morning of). This is proven to clean the colon better and is much easier to tolerate than drinking 4 liters at once.
  • Private Recovery Rooms: After your procedure, you wake up in a private bay with a dedicated nurse. You are offered juice and a light snack immediately.
  • Infection Control: We use automated washer-disinfectors that track every endoscope by serial number. We can trace exactly which machine cleaned your scope and at what temperature, ensuring 100% sterility.

FREQUENTLY ASKED QUESTIONS

Can I travel the day after a colonoscopy?

Yes. The sedative wears off fully in 24 hours. However, if we removed a large polyp, we might advise waiting 2–3 days before a long-haul flight to minimize the (very low) risk of delayed bleeding.

No. The capsule is great for the small intestine, but it is not a replacement for colonoscopy. It cannot take biopsies, remove polyps, or clean the colon walls. Colonoscopy remains the gold standard for cancer prevention.

Not at all. It feels like a gentle flick or vibration against the skin on your right side. There are no needles involved.

  • Average Risk: Start at age 45, then every 10 years if normal.
  • Family History: Start at age 40 (or 10 years before your relative was diagnosed), then every 5 years.

Previous Polyps: Every 3–5 years depending on the type and number of polyps found.

This is extremely rare at Liv Hospital because we use TIVA (Total Intravenous Anesthesia) administered by an anesthesia specialist, not just mild sedation by a nurse. The doctor monitors your brain activity and vital signs to ensure you stay asleep and comfortable throughout the entire procedure.
