title: [The use of Wallstent in malignant constrictions of the gastrointestinal tract].
abstract: Prosthesis implantation in malignant oesophageal stenosis, postoperative gastric outlet obstruction and jejunal stenosis is a quick and efficient method. The expansile metal stents are a new alternative to conventional plastic prosthesis. The Wallstent is made of surgical steel alloy elements braided in tubular fashion. The Wallstent is delivered in a small diameter device, but it expands to a much larger size after placement than the inner diameter of plastic stent. The small predilatations diameter makes implantation of the Wallstent less prone to cause complications or severe discomfort to the patient. The authors implanted seven Wallstents in six patients. One patient had oesophageal cancer, one ischaemic jejunal stenosis and four jejunal stenosis due to extraluminal tumour recurrences following total gastrectomy for cancer. The authors discuss in detail the usefulness of the Wallstent implantation in two cases with malignant disease of the oesophagus and jejunum. They remained symptoms free for 7 and 10 months after Wallstent implantation until death. Despite their higher initial cost, the metal stents are cost effective because of the absence of early and severe complications and the decrease in the hospitalization.
