Comparison of HGS versus CDS

	CDS	HGS
Technical considerations	Long endoscope position in duodenal bulb	Dilated intrahepatic duct of approximately 4 mm is required
Clinical benefits	Smaller diameter (6 or 8 mm) cautery-enhanced LAMs make procedure technically easier	Does not interfere with surgical resection Multiple luminal access points
Limitations	Difficulty managing stent misdeployment Might interfere with pancreaticoduodenectomy (Whipple) May be more stent occlusion due to food, particularly in GOO	Technically more challenging Lack of dedicated stents in most countries
