Fig. 2. Endoscopic view of antral web ablation. Mucosal tearing is evident by gaps within the gray mucosal tissue revealing dark muscular tissue of the pylorus underneath as viewed endoscopically through the balloon. Serial balloon dilatation using controlled radial expansion balloons (CRE; Boston Scientific, Marlborough, MA, USA) were inserted in the pylorus and gradually expanded first to 9 then to 10 mm, and then to 11 and 12 mm, then a third balloon was used to dilate to 13.5 mm and then finally 15 mm, ranging between 1 to 2 minutes at each session (2 minutes for the final two).
