Advanced procedures offered by Riverview Endoscopy

Endoscopic Submucosal Dissection (ESD) is a highly advanced, minimally invasive procedure used to remove early-stage cancers and precancerous lesions from the digestive tract without the need for surgery. Using a specialised endoscope, the lesion is carefully lifted and dissected from the deeper layers of the gastrointestinal wall, allowing for en-bloc (single-piece) removal.

This technique offers significant advantages over standard endoscopic resections or surgery, including organ preservation, faster recovery, and reduced complications. ESD allows precise removal of large or complex lesions in the digestive tract.

At Riverview Endoscopy, ESD procedures are performed by Dr Niroshan Muwanwella, an interventional gastroenterologist with extensive local and international experience in advanced therapeutic endoscopy. Our focus is on achieving complete resection with optimal safety, patient comfort, and long-term outcomes.

Zenker’s Per-Oral Endoscopic Myotomy (Z-POEM) is a cutting-edge, minimally invasive endoscopic procedure used to treat Zenker’s diverticulum, a pouch that can form at the top of the oesophagus and cause swallowing difficulties. Unlike traditional surgery, Z-POEM is performed entirely through the mouth using a flexible endoscope—no external incisions are required.

This advanced “third-space” technique allows precise division of the muscle responsible for the diverticulum, restoring normal swallowing and providing lasting relief. 

At Riverview Endoscopy, Dr Niroshan Muwanwella performs Z-POEM using the latest high-definition endoscopic technology, offering patients a safe, effective, and organ-preservingalternative to open surgery.
