abstract

  • BACKGROUND: An effort was made to assess the respiratory outcomes of laparoscopic Nissen fundoplication (LNF). METHODS: Prospective follow-up of 69 patients undergoing LNF for gastroesophageal reflux disease. Outcomes included pulmonary function testing, 24-h pH recording, esophageal manometry, and symptom assessment. RESULTS: There was an improvement (p < 0.0001) in heartburn and cough scores. There was a significant fall in spirometry (p < 0001), diffusing capacity (p < 0.0001), and respiratory muscle strength (p < 0.0001) 36 h after surgery, which had returned to baseline by 1 month. At 6 months, the patients (n = 16) with impaired preoperative diffusing capacity showed improvement (17.8 +/- 3.7 to 19.8 +/- 4.6 ml/min/mmHg, p = 0.0245). CONCLUSION: Patients undergoing LNF have impaired gas exchange before surgery which tends to improve 6 months after surgery. There is an early reversible impairment in respiratory function due to diaphragm dysfunction. Patients with a preoperative 1-s forced expired volume > 1.5, or 50% predicted, are unlikely to develop significant early respiratory complication.
