Box-whisker plots illustrating the seal-breaking pressure of ex-vivo lungs repaired by each method. There was a significant difference between lungs repaired using Methods 3 and 2 (p = 0.03) and Methods 3 and 1 (p = 0.03). Data were analyzed using the Wilcoxon rank sum test. In three out of the four cases repaired using Method 3, pressure measurements ceased because the intact pleura burst before the repaired site failed. Method 1: sprayed mixed fibrin glue over the PGA sheet. Method 2: using the finger-rubbing method, sprayed fibrinogen solution over the seat. Method 3: with gentle ventilation, the finger-rubbing method was performed and sprayed fibrin glue over the seat
