[Airtightness of intestinal anastomoses when laser resection technics are used]

Experiments were conducted on 168 dogs to appraise the biological and physical air-tightness of single- and double-row anastomoses formed on the small and large intestine after resection with a routine and laser scalpel. Microbiological, histological, histobacteriological, and statistic methods of examination were employed. A direct connection was revealed between the degree of infection of the abdominal cavity via the sutures of the anastomoses and the size of the destructive-inflammatory processes in the zone of the communication which depended on the type of the sutures and the method of resection of the intestine. The results allowed the expediency of using laser resection techniques and Pirogov's single-row suture to be substantiated from new standpoints (standpoints of higher biological air-tightness of the anastomoses).
