BACKGROUND gastric cancer patients are first diagnosed with an unresectable tumor in up to 40% of cases. Gastric outlet obstruction causes nausea, vomiting, dehydration and malnutrition. The aim of the study was to compare self-expanding metal stents to antrectomy and Roux-en Y gastrojejunostomy for palliation of obstructive adenocarcinoma of the gastric antrum. METHODS retrospective study in...
Very late stent thrombosis occurs in patients with bare metal stent implantation, although the annual incidence is much lower than that after drug-eluting stent implantation. In-stent neoatherosclerosis with ruptured plaques and thin-cap fibroatheromas has been observed in bare metal stents. Atherosclerotic plaques harvested from patients with very late stent thrombosis and those with acute cor...
Transl Androl Urol 2014;3(3):320 www.amepc.org/tau Although the concept of ureteral stenting has been around since the 1800s, it was not until the 1960s that the more modern version ureteral stents (at that time referred to as splints) were placed endoscopically. Many of the common problems with ureteral stents (irritative voiding symptoms, hematuria, encrustation, bacterial colonization, etc.)...
BACKGROUND & AIMS Plastic stents, placed via endoscopy to drain pancreatic fluid collections (PFCs), require repeat access. Covered metal stents are larger in diameter and can be inserted in a single step, but can migrate. We evaluated the safety and efficacy of a lumen-apposing, covered, self-expanding metal stent (LACSEMS) for PFC drainage. METHODS We performed a prospective study of the ou...
Background and aims. Dysphagia is the most common disabling symptom in patients with inoperable esophagogastric carcinoma. Self-expanding metal stents are highly effective in the palliation of these patients.Methods. In 35 patients with inoperable carcinoma of the esophagus or the stomach, with recurrent tumor or complications after transhiatal esophagectomy or gastrectomy or with esophageal st...
BACKGROUND Self-expanding metal and plastic esophageal stents (SEMS and SEPS, respectively) are used in conjunction with chemoradiation for palliation of malignant dysphagia. To date, the dosimetric effects of stents undergoing proton radiotherapy are not known. STUDY AIM To investigate the proton radiotherapy dose perturbations caused by esophageal stents of varying designs and materials und...
BACKGROUND Malignant airway obstruction is a feared complication and will most probably occur more frequently in the future because of increasing cancer incidence and increased life expectancy in cancer patients. Minimal invasive treatment using airway stents represents a meaningful and life-saving palliation. We present a new removable airway stent for improved individualised treatment. METH...
