RESUMO
Laparoscopic antireflux surgery is a minimally invasive procedure that should have similar results than classical surgical treatment. To report the results of a prospective study of laparoscopic antirelux surgery, 32 patients with gastroesophageal reflux and without Barret's esophagus, were subjected to endoscopy, amnometry and measurement of intraesophageal pH before and after laparoscopic surgery. Tehre were no postoperative deaths or complications. Gastroesophageal sphincter pressure and abdominal sphincter lenght increased from 9.1ñ3.9 to 13.0ñ3.5 mm Hg and from 8.1ñ6.2 to 13.5ñ5.4 cm after surgery (p<0.01). There was a decrease in acid reflux in 82 percent of patients. In conclusion, laparoscopic antireflux surgery reproduces exactly the results of open surgical procedures
