I believe care must be customized
to each patient because the practice
of medicine is not a “one size fits all”.

EGD

  • Complex esophageal stricture dilation
  • Percutaneous endoscopic gastrostomy (PEG) placement
  • Eradication of esophageal varices
  • Endoscopic mucosal resection (EMR) of esophageal, stomach, and duodenal polyps and lesions
  • Nasojejunal feeding tube placement
  • Esophageal stent placement for malignant obstruction or traheo-esophageal fistula
  • Duodenal wallstent placement for malignant gastric outlet obstruction
  • Large pneumatic balloon dilation for achalasia

COLONOSCOPY

  • Advanced techniques to reach cecum in previous unsuccessful colonoscopy
  • Large complex polypectomy using endoscopic mucosal resection (EMR)
  • Colonic wallstent placement for malignant obstruction
  • Eradication of hemorrhoids with endoscopic banding
  • Insertion of decompression tube for colonic pseudo-obstruction

ERCP

  • Ampullectomy
  • Direct-cholangioscopy with Spyglass
  • ERCP guided gallbladder stenting for cholecystitis
  • removal of complex biliary stones with electro-hydraulic lithotripsy

ENDOSCOPIC ULTRASOUND (EUS)

  • EUS-guided fiducial placement for stereotactic radiation therapy (Cyberknife)
  • EUS-guided pancreatic and biliary drainage in post-operative patients
  • EUS eradication of gastric varices
  • EUS- guided drainage of pelvic abscesses

ENDOSCOPIC SUBMUCOSAL DISSECTION (ESD)

  • What is an Endoscopic Submucosal Dissection (ESD)?
    ESD is an advanced endoscopic procedure used to remove gastrointestinal either early cancers or pre-cancerous tumors that have not entered the muscle layer of the wall of the gastrointestinal (GI) tract. ESD may be done in the esophagus, stomach or colon.
  • About the Procedure
    Under anesthesia, an endoscope is passed to reach the lesion in the esophagus, stomach, or colon. The removal part of the procedure consists of three steps:

    1. Injecting fluid into the middle wall layer or submucosa to elevate the lesion
    2. Cutting the surrounding superficial wall layer or mucosa of the lesion
    3. Dissecting the submucosa beneath the lesion
