Stapled hemorrhoidopexy uses a circular stapling device to excise a ring of rectal mucosa above hemorrhoidal cushions, lifting prolapsed hemorrhoids back into position. Less painful than traditional hemorrhoidectomy with faster recovery.
Hemorrhoid embolization (emborrhoid technique) uses catheter-delivered embolic agents to reduce arterial blood flow to hemorrhoidal tissue, causing shrinkage. A minimally invasive alternative to surgical hemorrhoidectomy.
Self-expanding stents are available for esophageal strictures, biliary obstruction, and colonic obstruction. They restore luminal patency in malignant or benign strictures, serving as bridge to surgery or palliative treatment.
