Endoscopic laser therapy for neoplastic lesions of the colorectum.
Surgical resection is the therapy of choice for most colorectal neoplasms. Endoscopic laser therapy (ELT) is a recently developed alternative for treatment of colorectal neoplasms and is applicable in a variety of clinical circumstances in which nonoperative treatment is preferable. The experience with ELT using the Nd:YAG (neodynium:yttrium-aluminum-garnet) laser in 42 patients was analyzed. The diagnosis was colorectal adenocarcinoma in 32 patients (76%) and neoplastic polyps in 10 (24%). ELT was undertaken either as a palliative treatment for malignant disease (60%), with curative intent for benign disease (26%), or as a temporizing measure (14%) in a total of 84 treatment sessions. Successful palliation or cure was achieved in 40 patients (95%) with 4 minor complications (9%) and no procedure-related deaths. This experience confirms ELT as an effective alternative to surgical therapy in the palliative, curative, or interim treatment of certain colorectal neoplasms in patients with prohibitive operative risk, limited anticipated survival, incurability, or diffidence toward operation.
