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.
