Summary
In 27 dogs esophagogastric anastomoses were performed in a single-layered end-on, a three-layered end-on and a double-layered inverting technique The anastomoses were reinvestigated on the 2., 4., 7., 15. and 30. postoperative . day. Suture line leakages were not observed. The inverted suture resulted in considerable anastomosic stenosis, ulceration of the mucosa, disordered and initially incomplete revascularisation, and widespread granulomatous inflammatory reaction. In contrast, the end-on technique led to almost no stenosis, ordered revascularisation, and narrow and delicate scar tissue formation while maintaining a normally layered structure. The single-layered methode was superior to the three-layered one. The best results were obtained by the extramucous technique.
Zusammenfassung
Bei 27 Hunden wurden einreihig-auf Stoß, dreireihig-auf Stoß und zweireihig-invertierend genähte transthorakale Oesophagogastrostomien am 2., 4., 7., 15. und 30. postoperativen Tag untersucht. Anastomoseninsuffizienzen wurden nicht nachgewiesen. Invertierende Anastomosen zeigten Stenosierung, Schleimhautulcerationen, unruhigen Gefäßdurchbau mit anfänglichen avasculären Bezirken und ausgedehnte granulierende Entzündung. Bei schichtgerechten Anastomosen fanden sich nur geringe Stenosierung, schichtgerecht geordneter Gefäßdurchbau und niveaugleiche zarte Vernarbung. Die einreihige Naht war der dreireihigen überlegen, wobei die extramuköse Technik das günstigste Resultat zeigte.
