“…All stents were inserted under radiological guidance using an 'over the wire ' Data were collected by review of patient case notes and investigation reports using a pro forma, and analysed using SPSS  version 15 (SPSS, Chicago, Illinois, USA). This study followed on from a previous series reporting on patients undergoing colonic stent insertion at this institution between September 1995 and May 2002 11 , but there was no overlap with the data reported here. In this study 'palliation' referred to use of SEMS to provide symptomatic relief in patients with co-morbidities rendering them unfit for surgical intervention, and 'elective' indicated a planned procedure, undertaken on the next available list.…”

“…The remaining patient died 1 day after stent insertion owing to sepsis from presumed bowel perforation, although no imaging was undertaken to confirm this and it is not known whether the perforation was secondary to stent insertion or ongoing obstruction. Similarly poor outcomes in this group were encountered in the previous series from this institution 11 .…”

Biodegradable stents can alleviate intestinal obstruction and stenosis in patients. The objective of this study was to develop a biodegradable polydioxanone (PDO) stent using weft-knitting technology and then investigate its biodegradation behaviors in vitro. PDO monofilament with linear density of 100 ± 10 tex was knitted into a tubular stent using a tubular weft-knitting machine. The physical and mechanical properties were evaluated according to the British standard BS EN 13895:2003 and ISO 7198:1998. The biodegradation behaviors of PDO weft-knitted stent in a phosphate buffer solution (pH = 6.8 ± 0.2, 37 ± 0.5 °C) were then investigated. The results showed that the stent maintained more than 60% of its original radial force above 12 weeks. During the 16 weeks of degradation, weight, crystallization, and pH change indicated the degradation medium was diffused into the chain segments of low molecular weight due to the rupture of ester bonds in the monofilament. Fourier transform infrared spectroscopy results demonstrated that the chemical structure of PDO polymer is stable during the in vitro degradation. In conclusion, this biodegradable stent can find valuable applications in treatment of intestinal obstruction and stenosis clinically.

Hintergrund: Die Implantation von selbstexpandierenden Metallstents (SEMS) in das Kolorektum – insbesondere als «bridge to surgery» – hat sich zunehmend etabliert, obwohl die Charakteristika des Kolons eine Prothesenimplantation erschweren und bisher noch keine optimalen Stents für diese Lokalisation verfügbar sind. Mit einem Stent lässt sich beim Kolonileus sehr patientenschonend eine sofortige Dekompression des Darms herbeiführen und die sonst notwendige Notfalloperation mit hoher Letalität und Komplikationsrate vermeiden. Methode: Literaturübersicht. Ergebnisse: Trotz zahlreicher positiver Studienergebnisse («... Stenting ist sehr effektiv, sicher und komplikationsarm im Vergleich zur Operation ...») ergibt eine kritische Analyse der Publikationen aufgrund vieler Faktoren (Patientenselektion, Stenttyp, Implantationsmethode usw.) jedoch eine hohe Heterogenität. Schlussfolgerungen: Um gute Resultate zu erzielen, sollte eine Stentimplantation ins Kolon nur nach strenger Indikationsstellung von einem erfahrenen Endoskopiker durchgeführt werden. Dabei ist auch die mögliche Alternative einer endoskopisch eingelegten Dekompressionssonde zu prüfen; ebenso sind onkologische Gesichtspunkte (chirurgische Resektion als einziger kurativer Ansatz) zu beachten.
