Objective: To assess the mechanical behavior of the main antireflux techniques in an experimental animal model.
Design: Prospective, experimental research
Setting: Third level health care general hospital.
Material and methods: The following antireflux techniques: Nissen, Toupet, Guarner, Collis, and Collis-Nissen were performed in 10 albino York pigs, weighing between 25 and 30 kg. The intragastric pressure was measured in each until gastroesophageal reflux was obtained. Basal pressure with and without insufflation was assessed. Statistical analysis: ANOVA and t tests, at a confidence level of 99% (p ‹ 0.01) were used.
Results: The basal intragastric pressure before insufflation presented a minimal value of –2 and a maximal of 1 mmHg (mean 0.90 ± 0.876 mmHg). Basal pressure with insufflation had minimal and maximal values of 7 and 12 mmHg, respectively (mean 10.4 ± 1,578 mmHg). Comparison of the pressures needed to produce gastroesophageal reflux with the different surgical techniques revealed a significant difference between the Nissen technique and those of Toupet, Guarner, and Collis (p = 0.001), and between the Collis-Nissen and those of Toupet, Guarner, and Collis (p = 0.001).
Conclusion: Complete antireflux techniques are mechanically more effective than the partial techniques.

Key words: Esophagus, hiatal hernia, surgery, antireflux surgery, animal model.
