“…Endoscopic stenting is used as a definitive treatment, a bridge to surgery, or a palliation of symptoms in patients with various gastrointestinal conditions, including benign or malignant strictures, obstructions, perforations, leaks, and fistulae. 1 , 2 It is a minimally invasive technique and thus is typically suitable for patients who are malnourished and frequently have multiple comorbidities. 2 …”

“…Rigid plastic stents were formerly used for the palliation of malignant strictures related to esophageal cancer. 1 The introduction of uncovered self-expanding metal stents (SEMS) in the early 1990s reduced the use of rigid stents 1 ; however, problems such as mucosal hyperplastic reaction (over- or in-growth) with subsequent obstruction of the stent were encountered. 3 Therefore, SEMS were fully covered with a silicone membrane to reduce ingrowth of granulation tissue.…”

“… 4 Unfortunately, covered stents are more apt to migrate, are less flexible, and have a shorter radial force. These problems prompted the development of partially covered metal stents with flared uncovered segments at both ends 1 , 4 , 5 and self-expanding plastic stents (SEPS) to minimize hyperplastic tissue reactions. 6 The need for removal is an important disadvantage of SEPS and SEMS.…”

Background and Objectives:Endoscopic stenting is a minimally invasive treatment modality for patients with various gastrointestinal conditions. We evaluated the safety and efficacy of uncovered biodegradable stents for postoperative leaks and strictures in the upper gastrointestinal tract.Methods:This was a retrospective study of patients treated endoscopically with biodegradable stents from January 2010 through November 2017.Results:Thirteen patients were enrolled, 7 of whom were men. Their mean age was 46 (range, 21–82) years. The indications for stent placement were postoperative leakage and stricture in 9 and 4 patients, respectively. The primary diagnoses were obesity in 7 patients, gastric cancer in 5, and peptic ulcer in 1. The average time to stent placement after surgery was 35 (range, 17–125) and 166 (range, 153–185) days for patients with postoperative leakage and stricture, respectively. Stent insertion was successful at the first attempt in all patients. Complete resolution of the leak and stricture was achieved after stent application in 11 patients, for a clinical success rate of 85%. The mean follow-up duration was 50 (range, 24–76) months. There were no major complications.Conclusions:Compared to self-expanding metal and plastic stents, the main advantages of uncovered biodegradable stents are that they do not have to be removed and have a low migration rate. Our results suggest that these stents have promise for management of postoperative gastrointestinal complications. Further randomized trials with larger sample sizes are necessary to determine the role of biodegradable stents in the treatment algorithm.

Esophageal stenting is used in patients with malignant esophageal tumours to reduce dysphagia and inanition. The objective of this study was to analyse the main reasons for esophageal stenting in Rīga East Clinical University Hospital (RECUH) and their association with dysphagia and mortality. A cross-sectional study of all patients hospitalised in RECUH who received esophageal self-expanding metal stents (SEMS) from October 2013 to December 2015 was performed. A total of 29 patients, 24 (82.8%) male and 5 (17.2%) female, with mean age 63.7 ± 11.3 years, underwent the procedure. The most common indications for stenting were tumour-related stenosis (52.9%) and fistulae (17.6%). Mean time from establishing the diagnosis of esophageal cancer to stent placement was 338.6 days. Median survival after stenting was 4.8 months. A complex case of a patient requiring placement of three palliative stents illustrates the challenges of esophageal cancer care. Esophageal stent placement is an effective palliative method for treating tumour-related symptoms but carries risks of stent complications and fistula development over time. SEMS are being successfully used in cancer patient treatment in Latvia.
