FIGURE 3. The feasibility of the hanging maneuver (2000–2005). The feasibility of the hanging maneuver clearly demonstrated leaning curve. The feasibility was significantly higher in the recent years than that in the initial years (143 of 152 [94.1%] in 2003–2005 vs. 58 of 76 [76.3%] in 2000–2002, P < 0.0001).
