In a previous randomized study, the tissue samples acquired were significantly larger with the use of the alligator forceps. Intuitively, the cup forceps, due to its smaller cup size, may yield smaller biopsy specimens.,, In the present study, the size of the biopsy samples, however, did not differ between the two groups, probably because we obtained at least four moderate-to-large tissue samples in both the study groups. The complication rate was also lower with the alligator forceps, similar to that reported in a previous study. It is likely that the cup forceps cuts through the blood vessels, whereas the alligator forceps crushes the blood vessels, thus leading to higher bleeding with the former method. In addition, the cup forceps has a smaller diameter (4 mm) compared with the alligator forceps (7 mm) in the open position; thus, it possibly reaches the lung segments more distally compared with the alligator forceps, leading to more pneumothoraces.
