[Palliative endoscopic intubation of esophago-gastric neoplastic stenosis: analysis of factors that may influence immediate results].

The paper examines a series of 172 patients undergoing endoscopic intubation with plastic stent due to unoperable esophago-gastric tumoral stenoses during the period 1980-1991. An analysis of the data enabled the following conclusions to be drawn: (1) The majority of perforations occur during the treatment of distal stenoses (15%), anastomotic stenosis (20%) and extrinsic compression stenoses (23% vs 7% in the case of stenosing primary esophageal neoplasia). (2) Severe respiratory problems may occur during treatment of cervical stenoses. (3) Malfunctioning of prostheses is more frequent in the treatment of cardias stenosis (10%). Having a few technical comments on the subject of passing the guide thread through the most twisting and narrow stenoses, the authors express the wish that expandable metal prostheses will be more widely used in order to render the method less traumatic, increase the percentage of success (extending the indications regarding the site and type of stenosis) and reduce severe complications.
