Villous adenomas of the rectum. Results of endoscopic treatment with argon and Nd:YAG lasers.

Endoscopic treatment of rectal villous adenomas with argon and neodymium:yttrium aluminum garnet lasers is reported in 56 patients. Patients treated include 25 who had polyp recurrence after non-laser polyp treatment, 8 who had small sessile polyps that would otherwise require major surgery, and 23 who had contraindications to surgery. Complete tumor ablation was documented over a 3-24-mo follow-up period in 42 of the 56 treated patients. Of the remaining 14 patients, 5 were referred for other therapy because invasive carcinoma developed during treatment, 5 could not be assessed with confidence because of radiation proctitis, and 4 were lost to follow-up. In all patients with symptoms, improvement was noted when 75% of the tumor was destroyed. Treatment was well tolerated with no major complications. The results compare favorably with conventional treatment. Because laser tissue destruction precludes complete histologic evaluation of polyp tissue, laser ablation of polyps should presently be limited to (a) patients with recurrent tumors after previous non-laser treatment who refuse surgery, (b) patients with serious contraindications to surgery, and (c) small benign tumors that would require major surgery.

[Gastric metastasis of a malignant melanoma of the choroid].

Gastric metastases of choroid malignant melanoma seem to be exceptional since less than 10 cases have been previously published. We report the case of a 71 year old patient with a gastric melanosarcoma secondary to a choroid malignant melanoma. Gastric metastasis was revealed by digestive bleeding occurring 18 years after right eye enucleation. Gastroscopy showed black ulcerated tumors. Histology confirmed the diagnosis portraying typical melanic pigments within the gastric mucosa. Laser photocoagulation of the gastric lesion was used for the first time in this indication. As a result, hemorrhage decreased and the patient's comfort was improved.
