[Boix Ochoa's antireflux procedure returns patients to normalcy: 24 hour esophageal pH monitoring of 21 cases].
A great controversy exist concerning the surgical management of gastroesophageal reflux (GER). It is well known that Nissen procedure produces a hypercorrection of the gastroesophageal competency and often a "gas bloat syndrome". On the other hand, the Boix Ochoa's technique is more physiological but corrects GER allowing the persistence of a "radiological" reflux. The aim of the study was to demonstrate the accuracy of this procedure. 287 pediatric patients were studied because of GER and abnormal barium upper gastrointestinal series. 24 hours esophageal pH monitoring was performed in all this patients and in 21 the results were clearly pathological. They were operated on and six months later were new evaluated with upper GI series and continuous 24 hours esophageal pH monitoring. The results were compared with those previous to operation and also with a control group. Statistical great significance was found between presurgical and postsurgical data, what determine the efficacy of the procedure. No statistical significance was found between postsurgical data and the control group, what means that Boix Ochoa's procedure resolve GER without hipercorrection.
