Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser therapy effectively treats gastrointestinal cancers and bleeding. This endoscopic treatment offers rapid symptom relief and improved outcomes for various conditions, including obstructive cancers and angiodysplasia.

Area of Science:

  • Gastroenterology
  • Oncology
  • Laser Medicine

Context:

  • Endoscopic laser therapy evolved from hemostasis to tumor destruction.
  • The Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser is prevalent in endoscopic gastroenterology.

Purpose:

  • To review the applications and efficacy of endoscopic Nd:YAG laser therapy in gastrointestinal conditions.

Summary:

  • Nd:YAG laser therapy rapidly alleviates dysphagia in 70-100% of patients with obstructive esophageal and cardia cancers.
  • It improves intestinal transit in 57-83% of colorectal cancer cases and controls rectal bleeding in 38-92%.
  • Sustained results require maintenance therapy every 4 weeks; it also treats villous tumors and controls gastrointestinal bleeding from angiodysplasia and Rendu-Osler-Weber disease.

Impact:

  • Provides a minimally invasive treatment option for patients unsuitable for surgery.
  • Offers significant symptom relief and improved quality of life for patients with GI malignancies and bleeding disorders.
  • Highlights the need for ongoing treatment to maintain therapeutic benefits.
