Background and Aim: Self-expandable metal stents (SEMS) are used for non-resectable malignant gastric outlet obstruction (GOO). Studies of covered versus uncovered SEMS have yielded inconsistent results as a result of heterogeneity in design and patient population. We carried out a meta-analysis to compare covered and uncovered gastroduodenal SEMS.Methods: Using MEDLINE, Embase, and the Cochrane database, we identified 1624 patients from 13 prospective and retrospective studies that evaluated covered and uncovered SEMS for malignant GOO and were published until October 2016. We pooled data on SEMS dysfunction, technical and clinical success, and adverse events using the fixed-effect or random-effects model. Conclusions: Outcomes of covered and uncovered gastroduodenal SEMS were comparable, although the lower dysfunction rate of covered SEMS observed in the analysis of randomized trials needs further investigation. Antimigration mechanisms for covered SEMS and identification of patients who can achieve longer patency from uncovered SEMS would help improve the outcomes of gastroduodenal SEMS. Results

“…48 The use of more permanent materials such as polytetrafluoroethylene (PTFE) or nylon has reduced this problem. 48, 49 Jang et al 48 reported an incidence of tumor overgrowth of 0.8% with the use of a dual stent covered with a nylon membrane with tumor obstruction occurring later after and more commonly in the duo- denal region. Some studies support that the use of chemotherapy after stent placement is associated with improved stents patency, 31,40 while others 50 studies show that it does not improve stent patency in patients with malignant GOO.…”

The treatment of malignant colonic and gastric outlet obstruction with self-expanding metallic stents (SEMS) is an established technique that can be performed by radiologic or a combination of radiologic and endoscopic guidance. The procedure is very effective to relieve the obstructive symptoms of advanced malignancies, with important clinical benefits and significant improvement in quality of life for the patients. Despite much advancement in the designs of SEMS, enteral stent placement is still associated with some significant early and late complications. Stent dysfunction mainly caused by tumor ingrowth/over growth, and stent migration when covered stent are used, are relatively common complications and many times require reinterventions.

“…7,9,26 Migration is much higher in fully covered braided stents, reported in up to 38% to 56% 7,26 and historically bare stents have been preferred. The membrane of double knitted or modular construction does not extend to the stent ends, allowing the bare metal to impress into the bowel mucosa.…”

“…The trade-off between the two primary modes of stent failure of stent occlusion by tumor ingrowth into bare metal stents and migration of fully covered stents have traditionally been reported as similar, ranging between 30% and 40% and increasing with survival. [5][6][7][8] Newer stent designs have tried to combine the anchoring capability of a bare stent with an additional membrane applied to the inside of the stent. Designs pursued currently, include metal stents where the membrane is sandwiched between two layers of metal and stents inserted as separate coaxial modules.…”

A B S T R A C TThe insertion of self-expanding stents into malignant strictures of the small and large bowel has become a routine procedure around the world. However, stent development has happened very much on a "trial & error" approach, based mostly on bright ideas of enthusiastic individuals or marketing decisions by the manufacturer. A large variety of stents are commercially available, covered to a variable degree by a membrane to reduce tissue ingrowth. However, in vitro characteristics and in vivo behavior vary significantly between stents and few operators are aware of the differences. While the ideal stent still remains to be defined, it is important that interventionists understand the variations, in order to make the best possible choice for the individual patient. This article illustrates current principles of stent construction.
