title: Nd-YAG laser applications in surgical endoscopy: a single center comprehensive experience.
abstract: A retrospective review of endoscopic procedures using the Nd-YAG laser was carried out for patients treated between September 1984 and November 1986. Two hundred twenty two procedures were performed on 104 patients (58M:46W) during this 26 month period. The study encompasses a unique period of time in this center, as it includes the initial use of the endoscopic laser technique, the learning curves associated with its application, and finally, the time when its use became routine. Treatment of tumors was the indication in 47 per cent of the cases. Gastrointestinal bleeding of benign cause was the indication in nearly half of the patients; arteriovenous malformations were the most common causes of bleeding. Laser photocoagulation of hemorrhoids was performed in 11 cases. Upper endoscopy was the route in 33 per cent of procedures. Anoscopy, flexible sigmoidoscopy, and colonoscopy were the routes in the remainder. The time spent on the procedure and the energy delivered were found to be variables of the type of lesion and the endoscopic route. Nd-YAG laser endoscopy can be used safely and effectively for a variety of bleeding and obstructive gastrointestinal conditions. Appropriate certification for granting of privileges to laser endoscopists is of utmost importance.
