Area of Science:

  • Oncology
  • Gastroenterology
  • Medical Technology

Background:

  • Surgical palliation for advanced gastrointestinal malignancy has high morbidity and limited success.
  • Unresectable tumors of the esophagus, stomach, and rectum often present with debilitating symptoms like obstruction, bleeding, and pain.

Purpose of the Study:

  • To evaluate the safety and efficacy of ablative laser therapy for palliation in patients with advanced gastrointestinal malignancy.
  • To assess the symptomatic response and impact on performance status following Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser treatment.

Main Methods:

  • A retrospective review of 30 consecutive patients with unresectable gastrointestinal tumors treated with endoscopic Nd:YAG laser therapy.
  • A total of 97 laser treatments were administered, with an average energy of 4525 joules per treatment.

Main Results:

  • Seventy percent of patients experienced a good to excellent symptomatic response.
  • Performance status improved in 19 of 20 patients with esophageal cancer.
  • The procedure demonstrated a low complication rate, with no perforations or fistulizations, and one 30-day mortality attributed to cachexia.

Conclusions:

  • Endoscopic Nd:YAG laser photo-ablation is a safe and effective palliative modality for advanced gastrointestinal cancers.
  • Laser therapy provides significant symptomatic relief and can improve quality of life in patients with unresectable GI malignancies.
  • Further treatment may be required for symptom recurrence, but the overall safety profile supports its use in palliative care.
