Standards recommended by the American Society for Gastrointestinal Endoscopy (ASGE).

Our liver and digestive system experts work together with a team of specially trained medical staff and use leading technologies to provide international standard diagnoses and treatments, from identifying the causes of illnesses in their initial stages through delivering highly technical treatment of digestive disorders. They work quickly, accurately and safely to ensure efficiency in the treatments we provide, improving our patients’ quality of life. Endoscopy experts are also on hand to consult alongside specialist physicians on the diagnosis and treatment of colon cancer. We offer treatment for Thais and foreign nationals using the latest medical equipment and technology, and meeting international standards accepted by medical professionals throughout the world. Our hospital has received Joint Commission International (JCI) accreditation.

The Liver and Digestive Institute at Samitivej Hospital has displayed a continued commitment to raising the level of treatment we provide. We have entered into a partnership with Sano Hospital, a leading hospital from Japan noted for its high level of expertise in the field of digestive endoscopic procedures, as well as in the analysis of the digestive mucosal wall, especially through image enhanced endoscopy. Prof. Yasushi Sano, Director of Sano Hospital and Director of the Liver and Digestive Institute, has a proven track record in his native Japan and is an innovator in terms of epithelium classification methods used to diagnose colonic polyps, making him highly regarded among Western physicians. Most recently, Samitivej Hospital has adopted two techniques from Japan which raise the standard of our services. The first technique, Narrow Band Imaging (NBI), is used to assist diagnosis of colorectal polyp irregularities that have the potential to develop into colon cancer. Not only can this technique detect polyps that are not yet protruding from the mucosal wall, but it also works up to 2 times faster than traditional detection techniques. The second technique we have adopted from Sano Hospital is endoscopic submucosal dissection (ESD), a form of minimally invasive, one-time surgery aimed at removing large polyps. The surgery, which does not involve opening up the patient’s abdomen, can be used to treat colon polyps and early stage stomach cancer. Crucially, the Liver and Digestive Institute is one of just a few private hospitals capable of carrying out liver transplants for patients suffering from serious liver conditions. Success rates for our liver transplantation procedures are as high as 90%, and most patients are able to make a full recovery.

The Liver and Digestive Institute uses innovative, state-of-the-art medical equipment necessary to provide speedy, accurate and reliable screening for a complete range of gastrointestinal and liver disorders including liver infections, alcohol poisoning, cirrhosis, fatty liver disease, pancreatitis, gallstones, stomach cancer, colon cancer, and many more related conditions. Our team of expert medical staff has experience from within Thailand and abroad. The Liver and Digestive Institute, located on the 1st Floor of The Japanese Hospital, Samitivej Sukhumvit Hospital, has a permanent staff of 11 doctors and 15 nurses working across 13 screening rooms, 5 endoscopy rooms and 10 recovery rooms.

The Liver and Digestive Institute provides services to both Thai and foreign nationals, with Japanese patients making up the largest percentage of the latter group. Each year, Samitivej Hospital provides treatment for up to 135,000 Japanese nationals, an average of 400 per day, making Samitivej Hospital the largest private care provider for Japanese people outside of Japan. We employ Japanese speaking medical staff who provide treatment and rehabilitation services in a warm, caring environment. We offer a range of convenient facilities which we believe can play a crucial role in helping our patients make a speedy return to full health. We assign a personal nursing assistant to each patient entering our hospital for treatment to ensure there is always someone close by who has a deep understanding of the patient’s situation and is fully aware of the subtle and important details of their treatment.

  • Endoscopic submucosal dissection (ESD) technique, a form of minimally invasive endoscopic surgery aimed at removing large polyps in a single procedure, without the need for open-abdomen surgery. The technique can be used to treat both colon and stomach cancers. Traditionally, when doctors detect an abnormality in the form of a regular polyp during an endoscopic procedure, they will remove the polyp immediately. However, there are limitations. Where polyps are large in size, a patient would have to undergo a separate operation to remove the large polyps or tumors. This is where ESD can be extremely helpful, as the technique enables surgeons to remove large polyps from the colon and stomach without the need for further surgery. ESD therefore reduces the risk of complications related to open-abdomen surgery, such as scarring, while also dramatically shortening hospital rehabilitation stays and reducing overall recovery time. All of this means patients can make a fast, safe and problem-free return to their daily lives.

The Liver and Digestive Institute specializes in endoscopy and offers fullcycle diagnostic services and treatment for diseases related to the liver and gastrointestinal (GI) system, such as viral hepatitis, alcoholic hepatitis, cirrhosis, fatty liver disease, pancreatitis, gallstone-related diseases and many more. Samitivej also specializes in cutting edge and tertiary treatments such as liver transplants. Today, liver transplants have a success rate of over 90% and most patients are able to resume their normal activities after recovering from the surgery.


Samitivej has entered into collaboration with Sano Hospital, a world leader in diseases of the GI tract and the classification of epithelial tissue, particularly in patients with abnormal epithelial tissue such as colonic polyps, colon cancer and stomach cancer. The two hospitals have also launched a medical exchange program providing an opportunity for Samitivej doctors to study innovative medical techniques from their counterparts in Japan.


Samitivej has adopted NarrowBand Imaging (NBI) International Colorectal Endoscopic classification (NICE) with magnification. This technology uses specific wavelengths of green and blue light to enhance the details and other obscure aspects of a gastrointestinal endoscopy. The efficacy of colon cancer screening is increased by offering the following benefits:

  • Enables earlier identification of colorectal diseases, even in the absence of physical tumors
  • Provides more accurate diagnoses leading to more precise treatments
  • Shortens medical procedures, promotes faster recovery and reduces complications, with no need for patients to stay at the hospital
  • If abnormalities are detected, biopsies can be taken safely, without the need for unnecessary surgery

The American Society for Gastrointestinal Endoscopy (ASGE) has determined quality indicators for colonoscopy in colorectal cancer (CRC) screening, which include cecal intubation success rate, average colonoscopy withdrawal time and adenoma detection rate (ADR). All standards have been met by Samitivej hospital, with ADR especially exceeding the standard. Overall ADR is recommended to be 25%. A higher ADR indicates an endoscopist who examines colons adequately and detects polyps effectively.  Samitivej’s current ADR (updated in 2015) is at 36.4% vs. 25% industry average (as laid out by The American Society for Gastrointestinal Endoscopy) and increasing after applying the NBI with magnification technique. We are thrilled that this innovative technique has raised the standards of our practice even higher. Currently, Samitivej Hospital is performing around 2,600 colonoscopies per year with no cases of complications during or after the procedure (2016). 

Part of our holistic approach includes the extra care provided by our medical personnel. For difficult treatments, each patient will be assigned a Case Manager. This is a nurse who has a complete understanding of their case and the importance of the care they are receiving. Learn more about the experience of our Case Managers here. 

The Liver and Digestive Institute uses the latest medical innovations and technologies. We are equipped with a team of specialists who draw from years of training and experience both in Thailand and abroad to provide Thai, expatriate and international patients with the most accurate diagnoses and best treatment plans for a variety of liverrelated diseases and digestive ailments.

Located on the second floor of Samitivej Sukhumvit Hospital, the Institute has 10 specialist doctors, 12 nurses, 4 technology experts, 12 examination rooms, 5 endoscopy rooms and 10 patient recovery rooms.
