RESUMO

OBJECTIVE: To provide a comprehensive follow-up of 381 patients after laparoscopic Nissen fundoplication (LNF) using a technique of minimal paraesophageal dissection. METHODS: Patients underwent a 24-hour pH recording, esophageal manometry, and symptom score assessment for six symptoms of gastroesophageal reflux disease preoperatively. To date, 260 patients have undergone repeat studies at 6 months and 108 patients at 2 years. RESULTS: LNF was associated with a significant (p < 0.0001) increase in the lower esophageal sphincter (LES) pressure and a significant (p < 0.0001) drop in duration of acid reflux in 24 hours and symptom score 6 and 24 months after surgery when compared to preoperative values. Twelve patients (3%) have experienced recurrence of reflux symptoms, 8 presenting in the first 6 months and 4 by the second year after surgery, but only 1 has required repeat surgery. The incidence of clinical dysphagia was found to be 1.3% of the patient group. CONCLUSIONS: LNF remains an effective antireflux procedure at 2 years. Most recurrences occur early, and there is no significant deterioration in the high-pressure zone at the LES, the percentage reflux in 24 hours, or symptom control between 6 months and 2 years after surgery, suggesting that the long-term results should be satisfactory.
