A Comparison of Bronchial Closure With the Aid of Staples or Suture: An Experimental Study on Pig Tracheae

Abstract

The objective of this study was to determine the resistance to pressure of a bronchial stump depending upon the closure technique. For the experimental study, 30 pig tracheae were alternatively closed either by a double-layer running suture at 90° to the cartilaginous rings or with an automatic stapling device. Sutures were placed under pressure until air leakage was observed. The air leakage pressure was digitally recorded. A statistically significant difference existed between the two groups. The mechanical suture proved more resistant to pressure (p= .011). Thus, under ideal conditions, the resistance to pressure of a mechnical suture is equal to, if not better than, that of the manual suture.
