[A comparative study of technics for intestinal anastomosis].

Two different intestinal anastomosis techniques were compared in 10 mongrel dogs. The first was classical enteral anastomosis (CEA) and the second was "U" suture enteral anastomosis (UEA) performed with "U" separated suture and inverted intestinal edges in one layer. The follow-up was over 21 days average. Once the follow-up was finished, animals were reoperated to obtain gut with CEA and UEA for macroscopic measures and microscopic studies with hematoxilin-eosin stains. UEA was easier and faster than CEA and lesser fibrotic and inflammatory tissue reaction were showed as well as lesser stenosis in UEA group. Both techniques had similar seal in anastomosis suture line as mean similar security. We think that UEA gives enough trust and security to be performed for good training surgeons.
