Dilation characteristics and measures of success.
| Patient | Size of stenosis at time of the first dilation (diameter in mm) | Max luminal diameter achieved by study end (mm)∗∗ | Time from TL to the first dilation (weeks) | Time from TL at study end (weeks) | Number of dilations at study end | Average time interval between dilations (weeks) | Retrograde approach used? | Lumen patency string in place (weeks) | Use of fluoroscopy | Diet/GT score∗∗∗: start of the study period | Diet/GT score: end of the study period | Technical success? | Clinical success? |

∗Complete lumen occlusion. ∗∗Max luminal caliber achieved prior to dilation during the study period. ∗∗∗Diet/GT scale: Score 1 = GT present and NPO, Score 2 = GT present and liquid/pureed diet, Score 3 = GT present and soft/regular diet, Score 4 = no GT and liquid/pureed diet, and Score 5 = no GT and soft/regular diet. ∗∗∗∗GT recommended but patient refused.
