Retrograde percutaneous enterostomies in children using a needle system with valve mechanism

The technique of enterostomy access frequently uses a needle preloaded with a suture anchor to appose the bowel wall to the abdominal wall. Two of the intrinsic disadvantages of this method are the possible dislodgment of the suture anchor out of the needle hub during the process of guide-wire insertion and the escape of air with subsequent deflation of the viscus, which may necessitate a second puncture. The use of a Check-Flo performer assembly with a valve mechanism provides a leakproof system. It avoids possible dislodgment of the suture anchor during deployment, maintains viscus distension, and may be useful for trainees to do the procedure in a controlled manner.
