N2 - Balloon dilatation is a standard therapy for gastrointestinal luminal narrowings. The choice of hydrostatic balloon dilator brand that has been used was arbitrary. The purpose of this invitro study was to compare the dilating force of hydrostatic balloon dilators. METHODS: The balloon dilator brands tested were Achiever™ (Microvasive, Natick, MA), Eliminator™ (CR Bard, Inc., Tewksbury, MA) and MaxForce TTS™ (Microvasive, Natick, MA). Diameter sizes of each brand tested were: 6mm, 8mm, 10mm, 12mm, 15mm and 18mm. Each balloon was placed in a water bath at body temperature and inflated to the manufacturer's suggested pressure within a Chatillon Digital Force Gauge (DFGS50). Dilatation force was measured five times with each balloon dilator brand within a fixed metal narrowing that was 2mm smaller than each maximum balloon diameter. RESULTS: BALLOON BRAND AVERAGE RADIAL FORCE (lbs) STANDARD DEVIATION Achiever™ 10.9 0.8 Eliminator™ 28.3 3.5 MaxForce TTS™ 34.5 7.0 CONCLUSIONS: The MaxForce TTS™ delivered significantly higher average dilating force than the Eliminator™ and Achiever™ (P<0.05). The Eliminator™ delivered a significantly higher average dilating force than Achiever™ (P<0.05). The choice of dilator is no longer an arbitrary decision if one assumes that dilating force is clinically important. However, further research must be done to determine the effect of dilating force on patient outcomes.
