Mean ± SD area measurements [mm2] and epithelial score for the quadrants (Q) 1–4 for each group (3M: n = 7; 6M: n = 5; 12M: n = 6). LC—lumen of the control; SC—area of secretion (control); AS—area of the stent; LT—area of the total ET lumen; L—area of the lumen within the stent; S—area of L taken by secretion; T—area of AS occupied by tissue; SR—area of secretion outside the stent lumen.
