Application of mechanical and manual sutures enclosing the bronchus.

The mechanical suture was introduced into thoracic surgical procedures by Amonosow and Androsow, Soviet surgeons, in the late 50s. The aim of the paper is to compare the incidence of bronchopleural fistulae that develop after the mechanical suture has been applied in bronchus surgery with the corresponding figures for traditional manual sutures. In the period of January 1997-March 1999 a series of 524 anatomical lung parenchyma resections was performed at the Department of Thoracic Surgery, Medical Academy of Gdańsk. In 460 cases (87.8%) the indication for the procedure came from primary lung carcinoma, and in 64 cases (12.2%) from tuberculosis, hamartoma, arteriovenous fistula, inflammatory lesions, asperpilloma, and metastases to the lungs. Depending on the way the bronchus was surgically closed the patients were subgrouped as follows: group I comprised 209 subjects (40.6%) whose bronchus was closed with a mechanical TA Premium Auto Suture, and group II that embraced 306 subjects (59.4%) whose bronchus was closed with a manual PDS 3/0 or Maxon 3/0 suture. The bronchopleural fistula developed in 11 cases of which 5/216 (2.3%) had the bronchus stump closed with a mechanical suture, and 6/308 (2.0%) cases had it closed with a manual suture. Of 11 cases of bronchopleural fistula 10 cases were noted after pneumonectomy. After the right side pneumonectomy, one fistula was discovered following the application of mechanical suture and six fistulas were found when the manual suture was used. After the left side pneumonectomy, no fistulae were discovered when the manual suture was used, and 3 those found were exclusively present when the mechanical suture was applied.
