Endoscopic Mucosal Resection (EMR)


What is Endoscopic submucosal resection?

Endoscopic submucosal resection is a minimally invasive advanced endoscopic procedure that is used to remove or resect pre-cancerous or early cancerous lesions of the gastrointestinal tract (GI).

Lesions or masses are isolated and fluid is injected underneath to ‘lift’ the area. It is then cut out using a thin wire (snare) fed after forming a loop circumferentially around the tumor.

An electrical current is passed through the wire which both removes the tumor and also cauterizes the wound.


     Indications: -


  1. Early cancers or microinvasive cancers of the upper gastrointestinal tract like the esophagus, stomach, or duodenum 

  2. Masses or polyps (< 2 cm) in the lower gastrointestinal tract, especially neoplastic polyps 

  3. Barrett’s esophagus



   Advantages of SMR over surgery

    1. Minimally invasive procedure 

    2. Complete resection prevents the spread of cancer 

    3. Accurate staging and grading 

    4. Minimal stay in the hospital (1-2 days max) 

    5. No complications 

    6. Excellent prognosis

What is Achalasia?

Image
 Achalasia Achalasia is an esophageal disorder caused due to tightening or contraction of the lower portion of the esophagus (as it loses the ability to relax). The esophageal musculature around the lower esophageal sphincter is affected leading to unopposed contraction.  The exact cause is not yet known, but its pathogenesis has been linked to loss of neurons (nerve cells) which help dilate the esophagus Signs and Symptoms  1. Feeling of food getting ‘stuck’ in the chest. 2. Abrupt onset of difficulty in swallowing both solids and liquids. 3. Heartburn  4. Vomiting of food undigested food particles  5. Pain in the chest that is waxing and waning i.e (comes and goes) Evaluation  1. Upper Endoscopy to rule out other structural causes of esophageal dysphagia.  2. Esophageal manometry  Management  The type of therapy is decided by considering the severity of signs and symptoms and investigative evaluation. Medical therapy is instituted if the di...
