At the Institute, the focus is to give affordable comprehensive, state of the art Gastrointestinal care to all needy patients. The Institute has two major Divisions : Medical Gastroenterology and Gastro intestinal Surgery .The institute has a group of experienced, well trained physicians including Gastroenterologists, Hepatologists, Gastrointestinal surgeons, GI pathologists, Radiologists , Anesthetists and paramedical staff who work as a team. The various divisions cater to different categories of patients.

Advanced Endoscopy Center

The Center, recognised by the Society of Gastrointestinal endoscopy of India has a 16000 Sq ft endoscopy suite with all the state of the art endoscopy equipments including EXERA CV – 190 Olympus endoscopes, EU ME-2, Alfa 5 and F75 EUS units with Radial, Linear and Forward view EUS scopes as well as mini probes and intraductal probes, Siemens flat panel Axiom Luminos DRF fluoroscopy unit, GIVEN imaging Capsule endoscopy and spyglass cholangioscopy. The EUS Center is one of the most advanced in the country. Therapeutic EUS was first introduced to Kerala state by PVS Institue. EUS guided procedures are used to stage cancers and treat patients with pancreatic pseudocysts, bile duct obstruction etc. Pancreatobiliary unit deals with all pancreatic and bile duct diseases including chronic pancreatitis, pancreatic and bile duct tumors and provides advanced endoscopic treatment when needed. The spyglass cholangioscope is used to diagnose bile duct diseases and also treat large bile duct stones. Guided Radiofrequency ablation is done for inoperable bile duct malignancies. ERBE 300 unit with water jet is an added advantage for procedures like POEM for Achalasia Cardia, STER and Endoscopic submucosal dissection of superficial tumours of GIT. The endoscopy Center has one of the best scope reprocessing and disinfection system in the country, including fully automated Olympus scope reprocessor and Ultra sonic cleaner as well facility for ETO sterilization for accessories if required. Regular quality check with bacterial culture is maintained in the unit. We introduced packages for use of disposable endoscopic accessories (one time use) in the unit probably first time in India.

Aixplorer Supersonic Imagine

First hospital in Kerala to have this highly advanced Machine. Aixplorer® MultiWave™ Technology provides impeccable image quality and non-invasive, real-time, quantitative ShearWave™ Elastography (SWE™) for the Qualitative and Quantitative treatment monitoring – Anti Viral Therapy and Antifibrotic Drugs - to better image the progression or regression of liver diseases. This system leverages a unique Multi-Wave™ Technology that enables to detect, characterize and, in the future, treat palpable and non-palpable masses. Aixplorer is the first ultrasound system to provide you with the following imaging benefits of ShearWave Elastography: A real-time SWE map of liver elasticity to help accurately determininig the stiffest areas for measurement and biopsy As the SWE color-coded map is superimposed over the B-mode image, the user can verify the acquisition is in the liver, preventing incorrect measurements in the kidneys or in near-by vessels. Liver elasticity measurements can be obtained in challenging cases of obesity and ascites, with a depth of up to 12 cm A fast, real-time stiffness acquisition which is not affected by movement of the patient or the operator Operator skill independence and ease of use.Preliminary studies show that SWE is not only equivalent to the currently accepted techniques used to evaluate liver stiffness, but also has improved specificity and accuracy. It may also help in Characterization of Focal Liver Lesions (HCC/FMH/Cholangiocarcinomas/Hemangiomas) using Realtime Shearwave Elastography & CEUS.
