Laser effects on biological tissue depend on wave-length, power-density (W/cm2) and duration of pulsed radiation. Thermal effects may be used for cutting, coagulation and vaporisation. Non-linear effects such as photoablation or photo-disruption are suitable for non-thermal tissue ablation and shock waves can be induced to destroy concrements. Laser is mostly used in clinical surgery for endoscopic treatment of gastrointestinal bleeding and tumors. Laser angioplasty, arthroscopic laser treatment and laser lithotripsy are not yet widely applicable in clinical practice.

UI	MeSH Term	Description	Entries
D007415	Intestinal Obstruction	Any impairment, arrest, or reversal of the normal flow of INTESTINAL CONTENTS toward the ANAL CANAL.	Intestinal Obstructions,Obstruction, Intestinal
D008096	Lithotripsy	The destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. Focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. Lithotripsy does not include the dissolving of stones by acids or litholysis. Lithotripsy by laser is LITHOTRIPSY, LASER.
