In this series of four patients, some modifications of the standard over-the-wire
(OTW) technique for stent deployment using the balloon overtube normally used in single-balloon
enteroscopy are presented. This modified technique allowed the use of OTW stents in
patients where there were difficulties that meant the standard technique was unsuccessful.
For each patient, the authors describe different small novel adaptations of this modified
technique that enabled self-expanding metal stents (SEMSs) and biodegradable stents
to be successfully deployed in different gastrointestinal locations. Moreover, in
one patient the stent was placed without fluoroscopic guidance.
