ND-YAG LASER VERSUS POLIDOCANOL INJECTION FOR PALLIATION OF ESOPHAGEAL MALIGNANCY - A PROSPECTIVE, RANDOMIZED STUDY

Palliation is often the only treatment that can be offered to patients affected by esophageal malignancy. This prospective study was carried out in order to compare two endoscopic palliative treatments: Nd:YAG laser and local injection of 3% polidocanol. We randomized 34 patients with inoperable malignancies to one of the two treatments. After the first course, 88.8% of the patients in the laser group and 81.5% in the polidocanol group were able to swallow a normal oral caloric intake. Only one major complication (esophageal perforation) was observed (polidocanol group) and was successfully treated with endoscopic placement of a prosthesis. We believe that both techniques are safe and effective for the palliation of esophageal malignant strictures but that polidocanol injection is cheap, simple, and more widely available.
