Endoscopic polypectomy, dilation, stent

• Authorization will be arranged by the rooms or hospital staff if required.

• Fasting:

• No solid food for 6 hours before the procedure

• No clear liquids for 2 hours before the procedure

• Bowel preparation may be required for lower gastrointestinal procedures.

• Most chronic medications may be taken unless advised otherwise.

• Inform your doctor if you are taking blood-thinning medication.

• Diabetic medication instructions will be discussed in advance.

​These procedures are performed under sedation. You will be monitored throughout and observed in recovery until the sedation has worn off. Therapeutic interventions are performed only if it is safe to do so.

The type of intervention performed depends on the findings during endoscopy.

Endoscopic Polypectomy

• Polyps are removed using a snare, cautery, or biopsy forceps.

• Removal reduces the risk of progression to cancer.

• The tissue is retrieved and sent for histological analysis.

Endoscopic Dilatation

• A narrowed area is gently stretched using a balloon or dilator.

• This improves swallowing or bowel passage.

• Multiple dilatation sessions may be required in some cases.

Endoscopic Stent Placement

• A self-expanding metal or plastic stent is placed across a narrowed or obstructed segment.

• Stents may be temporary or permanent.

• This is commonly used for obstruction caused by cancer or severe strictures.

The procedure usually takes 20–60 minutes, depending on the complexity and number of interventions performed.

• Bleeding (more common after polypectomy)

• Perforation (tear) of the oesophagus, stomach, or bowel

• Infection

• Pain, bloating, or cramping

• Stent migration or blockage (if a stent is placed)

• Need for repeat procedures

• Reaction to sedation

• Unintended damage to surrounding structures

• Complications are uncommon. Contact the rooms or seek urgent medical attention if you experience severe pain, persistent bleeding, black stools, fever, vomiting, or difficulty swallowing after the procedure.

• These are usually day procedures, and most patients go home the same day. Some patients may require short admission for observation, especially after stent placement.
