As for the gastrointestinal tract, stents are most commonly applied in the esophagus. Majority of the esophageal stents are implanted for the purpose of palliation of the inoperable malignant dysphagias, however they may also be used, although less frequently, for dilatation of the constricted anastomosis, covering of fistulas and least frequently for dilatation of the benign stenoses. Increasingly frequently the stents are used in the prepyloric gastric region, duodenal and rectosigmoid portion of the colon. The paper describes our own six-year experience in application of the gastrointestinal stents for palliation of dysphagia.

ABSTRACT: The purpose of this study was to evaluate technical and clinical results of self-expanding esophageal stent implanted in patients with malignant esophageal strictures and clinically significant dysphagia. From June 1992 to September 1994, 27 patients with inoperable tumors of the esophagus or gastric cardiac were treated by placement of 37 self-expanding nitinol stents. Water-soluble contrast and endoscopy studies were performed after the procedure and during the follow-up period. Successful stenting of the stricture was achieved in 27 patients. The mean dysphagia grade dropped from 2.3 to 1 (SD +/- 0.54) immediately after the procedure. After the insertion of the stent, 16 patients died in a period of time ranging from 0 to 13 months (mean 5.6 months), whereas at the end of the study 11 patients were alive 4-15 months after the procedure (mean 8.3 months). No major complications were observed. The results of this study are encouraging because esophageal stent placement was technically easy and clinically effective.European Radiology 02/1996; 6(2):230-5.

ABSTRACT: In a pilot study between May 1988 and May 1989, ten consecutive patients with advanced esophageal cancer were treated with a short intensive course of intraluminal curietherapy without external beam irradiation at the Kaiser Permanente-Los Angeles Medical Center. Nine of ten patients achieved effective palliation comparable to that of standard external beam teletherapy from other series. Most patients had already failed other palliative modalities including chemotherapy, laser debridement, dilation, and electrocautery. The duration of response was generally longer than with these techniques. All patients completed therapy, and tolerance was excellent. Intraluminal irradiation is an attractive, effectual therapeutic alternative, especially in patients with advanced local or distant disease unlikely to tolerate 5 to 7 weeks of external beam therapy.Journal of Surgical Oncology 08/1990; 44(4):234-7.
