Spy Glass Laser Endoscopy
The only tertiary care center in Trichy to do spyglass endoscopy. Spyglass endoscopy is a state-of-the-art technology done on patients to diagnose and treat CBD stones. It plays a major part in diagnosing and sampling CBD cancers.


Endoscopic Ultrasonography
EUS (endoscopic ultrasonography) is a minimally invasive procedure that combines endoscopy and ultrasonography to create detailed images of the digestive tract and surrounding organs. It is used to diagnose and treat a variety of conditions, including cancer, pancreatitis, and gallstones.
24 Hours Ambulatory Oesophageal pH Monitoring
Oesophageal 24-hour pH/impedance reflux monitoring measures the amount of reflux (both acidic and non-acidic) in your esophagus during a 24-hour period, and assesses whether your symptoms are correlated with the reflux.


High Resolution Spatiotemporal Manometry
High Resolution Spatiotemporal Manometry (HRSM) is an innovative diagnostic tool in gastroenterology that assesses esophageal motility and pressure patterns with exceptional accuracy. By employing advanced sensors and presenting data as detailed, color-coded topographic maps, HRSM offers valuable insights into conditions such as dysphagia, achalasia, GERD, and esophageal spasms. This minimally invasive method improves diagnostic accuracy, supports personalized treatment planning, and marks a significant leap forward in the diagnosis and management of esophageal disorders.

Fluoroscopy
Fluoroscopy is a medical imaging procedure that uses X-rays to produce real-time images of internal structures and motion. It is used for a variety of diagnostic and therapeutic procedures, such as barium swallow, cardiac catheterization, arthrography, and interventional radiology procedures. Fluoroscopy is a safe and effective procedure, but it does expose patients to some radiation.
