Quick Answer
Endoscopic ultrasound (EUS) places a high-frequency ultrasound probe directly inside the gut, producing the most detailed images possible of the pancreas, bile duct and surrounding organs. Dr. Anando Sengupta performs both diagnostic EUS (with FNA / FNB biopsy) and therapeutic EUS (pseudocyst drainage, coeliac block, biliary drainage) at Fortis Hospital, Shalimar Bagh.
Diagnostic EUS
| Indication | What EUS shows |
| Pancreatic mass | Size, vascular invasion, lymph nodes, FNA biopsy |
| Pancreatic cysts (IPMN, MCN) | Wall features, mural nodules, fluid analysis |
| Bile duct stones | Distal CBD stones missed on MRCP |
| Sub-mucosal tumours (GIST, leiomyoma, lipoma) | Layer of origin, size, vascularity |
| Mediastinal & abdominal lymph nodes | Characterisation + FNA |
| Rectal cancer | T-staging, sphincter involvement |
| Chronic pancreatitis | Parenchymal & ductal changes (Rosemont criteria) |
Therapeutic EUS
- EUS-guided pseudocyst drainage — transgastric or transduodenal stenting
- EUS-guided drainage of walled-off necrosis with lumen-apposing metal stents
- EUS-guided coeliac plexus block / neurolysis — for pain in chronic pancreatitis or pancreatic cancer
- EUS-guided biliary drainage — when ERCP fails
- EUS-guided gastrojejunostomy for gastric outlet obstruction (selected centres)
Why EUS-FNA is so valuable
Pancreatic and lymph-node lesions are often deep and inaccessible to standard biopsy. EUS-FNA brings the needle to within millimetres of the target under real-time ultrasound guidance, achieving over 90% diagnostic accuracy with minimal complications. This is the standard of care for diagnosing pancreatic cancer.
Frequently Asked Questions
EUS is a procedure that combines endoscopy with ultrasound. A specialised endoscope with an ultrasound probe at the tip is passed into the upper or lower GI tract to obtain very high-resolution images of organs adjacent to the gut wall — the pancreas, bile duct, mediastinum and rectal wall — along with biopsy capability.
EUS is used to evaluate pancreatic masses and cysts (with or without FNA biopsy), stage gastrointestinal cancers, characterise sub-mucosal lesions, biopsy lymph nodes, drain pancreatic pseudocysts, perform coeliac plexus block, and guide a number of advanced therapeutic procedures.
No. EUS is performed under deep sedation or general anaesthesia, similar to regular endoscopy. Most patients feel only mild bloating afterwards.
Diagnostic EUS takes 20–45 minutes; therapeutic EUS (cyst drainage, coeliac block, EUS-guided ERCP) can take 60–90 minutes.
Once a target lesion (pancreatic mass, lymph node, sub-mucosal tumour) is identified on EUS, a fine needle is passed through the endoscope and into the lesion under real-time ultrasound guidance to obtain cells or core tissue. Diagnostic accuracy is over 90%.
Diagnostic EUS at Fortis Shalimar Bagh: ₹25,000–₹40,000. EUS-FNA / FNB: ₹40,000–₹60,000. Therapeutic EUS varies depending on stents and accessories used.
Yes. Dr. Anando Sengupta consults at North Delhi Nursing Home, Ashok Vihar Phase II (Mon–Sat, 5:30–7:30 PM) — within easy reach of Model Town (3 km), GTB Nagar, Mukherjee Nagar, Wazirpur and Shastri Nagar. Morning slots and procedures (endoscopy, colonoscopy, ERCP, EUS) are at Fortis Hospital, Shalimar Bagh (~3 km from Pitampura, with cashless insurance on all major panels). Both clinics serve patients from across North Delhi.
