11 META-ANALISI di 9 studi randomizzati (4 Nissen vs Toupet e 5 Nissen/Toupet vs Dor) better reflux control after Nissen fundoplication it has been consistently shown that tailoring antireflux surgery according to esophageal motility is not indicated there is significance evidence that anterior fundoplication offers less effective long-term reflux control GERD

34 CONCLUSION LA CHIRURGIA FUNZIONALE NON PUO’ PRESCINDERE DA UNA ATTENTO STUDIO FISIOPATOLOGICO. QUESTO VALE SIA PER LA SELEZIONE DEI PAZIENTI CHE PER IL CONTROLLO DELLA CORRETTA FUNZIONE DELL’INTERVENTO NEL TEMPO. GLI STUDI DI CHIRURGIA FUNZIONALE HANNO A LORO VOLTA COSTITUITO UN VALIDO MODELLO PER UNA AVANZAMENTO DELLA CONOSCENZA DELLA FISOLOGIA E DELLA FISIOPATOLOGIA.
