Postoperative wound healing is studied after tracheal suturing in 5 pr
imates operated on in two stages. First by double level hemisection co
mparing continuous and interrupted sutures with polydioxanone. In a se
cound stage:comparison of continuous sutures after tracheal segmental
resection. The tracheas were harvested sequentially to study the evolu
tion of the sutured zone by measuring its diameter and by histopatholo
gic examination. The reduction of the tracheal diameter observed was n
ot statistically significant after hemisection using continuous (p = 0
.7) or interrupted sutures (p = 0.6). But after tracheal resection the
stenosis was significant with continuous sutures (p < 0.05). Histolog
ic study revealed that polydioxanone is well tolerated and is absorbed
within 26 weeks. The authors recommend the use of continuous sutures
to repair simple wounds and of interrupted sutures after tracheal rese
ction anastomosis.
