Endoscopic palliation for inoperable malignant dysphagia: long term follow up.

This prospective non-randomised trial of 128 selected patients with unresectable oesophageal or gastrooesophageal junction cancers aims to evaluate the initial relief of malignant obstruction by means of bipolar electrocoagulation for both circumferential and submucosal strictures of Nd:YAG laser for the other patients. A limited dilatation was performed initially if a small calibre endoscope was unable to pass through the stricture. Prompt and significant relief of dysphagia without complications was achieved in 83% of patients.

[Laser treatment of rectosigmoidal tumors: long-term results].

Over a 10 year period, 530 patients were treated at the Lille Laser Center for a rectosigmoid tumour. Both argon and Nd:YAG lasers were used. Two hundred patients were treated for palliation of symptoms from a rectosigmoid cancer, 313 patients were treated for a rectosigmoid villous adenoma, and 17 patients with a familial polyposis were treated for the rectal polyposis remaining after total colectomy.

[Laser treatment of rectosigmoid villous tumors. Study of a series of 313 patients].

Endoscopic laser treatment is reported in 313 patients with benign rectosigmoid villous adenomas. Total tumor destruction was achieved in 92% of them, without any major complications. The circumferential extension of the tumor base was the only factor affecting this result.

Endoscopic laser treatment for rectosigmoid villous adenoma: factors affecting the results.

Endoscopic laser treatment is reported in 264 patients with benign rectosigmoid villous adenomas revealed by biopsy. Patients include 100 who had contraindications to surgery, 60 who had a tumor recurrence after a nonlaser treatment, 101 for whom surgical resection appeared to be too drastic for a tumor found benign on biopsy, and 3 who refused surgery. Two types of lasers were used: the Nd:YAG and the argon laser.
