Abstract

The objective of this study was to perform an experimental study to be compared under the pathological-anatomic, point of view, the manual and mechanical sutures in the main bronchus after left pneumonectomy in dogs. Eighteen adult mongrel, healthy dogs, both male and female, were utilized weighing from 9 to 27.5 kg. The dogs were submitted to a selective intubation and left thorax incision in the 5 th intercostal space where a pneumonectomy was performed. Were separated into 2 groups of 9 dogs according to the type of suture employed: Group A - a manual suture with polypropylene 5-O; Group B- a mechanical suture with a mechanical stapler, model TL-30. Each group was subdivided into 3 subgroups of 3 animals and a temporal postoperative study was established at 7, 15 and 36 days where an pathological-anatomic evaluation was made on the healing of the manual and mechanical sutures. During the histopathological evaluation, the intensity of inflammation, fibrosis, neoformed vessels, and the presence or absence of granulation tissue, foreign body reaction and necrosis were evaluated qualitatively and semi-quantitatively. The results found were analyzed statistically. Regarding the histopathologic analysis, foreign body reaction occured in the left bronchial stump in 88,9% of the dogs submitted to a manual suture and in none of the dogs submitted to a mechanical suture. There is still, significant statistical difference in the dogs in Groups A and B in relation to the intensity of the inflammation, the greatest intensity being in the dogs submitted to the manual suture. It is concluded that both types of sutures brought an adequate healing of the main left bronchial stump, although there was a greater intensity of inflammation and a greater occurence of foreign body reaction in the dogs submitted to the manual suture.
