This report describes two cases of oesophageal tumours managed by transendoscopic neodymium:yttrium-aluminum-garnet laser ablation and polypectomy snare electrocautery. In each dog oesophagoscopy revealed caudal oesophageal masses, suspected to beSpirocerca lupi-induced oesophageal neoplasia. To resect the masses, transendoscopic neodymium:yttrium-aluminum-garnet laser ablation was used in the first case and polypectomy snare electrocautery in the second. Recovery was uneventful. Histopathology was consistent with oesophageal fibrosarcoma and osteosarcoma in each case, respectively. Follow-up oesophagoscopy revealed apparently healthy oesophageal tissue except for focal scar tissue in the first case. Transendoscopic laser ablation and polypectomy snare electrocautery is a potential non-invasive, cost effective alternative for surgical oesophageal mass resection.
