Successful management of severe gastroesophageal reflux disease with laparoscopic Nissen fundoplication

Abstract

Background: Nissen fundoplication has been shown to be superior to medical treatment in the management of severe or complicated gastroesophageal reflux disease (GERD). Rapid advances in minimally invasive surgical technique and recognition of the advantages of reduced incision-related morbidity have fostered application of laparoscopic techniques to antireflux surgery. A prospective evaluation of 70 patients undergoing laparoscopic Nissen fundoplication for severe GERD was undertaken.

Patients and methods: Rigid selection criteria for laparoscopic Nissen fundoplication included severe or refractory disease with documentation of abnormal esophageal acid exposure by 24-hour pH probe monitoring, documentation of a mechanically defective lower esophageal sphincter by esophageal manometry, and absence of severe esophageal and/or gastric motility disorders.

Results: Sixty-eight of 70 patients were completed laparoscopically with an intraoperative morbidity rate of 9%. Major postoperative complications occurred in 3 patients (4%) and included deep venous thrombosis (n = 1), delayed gastric leak (n = 1), and trocar site hernia (n = 1). The average hospital stay was 3.0 days, and the average time to return to normal activity was 7.0 days. All patients experienced relief of symptoms of reflux with mean follow-up of 7.7 months. Transient, mild dysphagia was experienced by 37% of patients, and persistent, severe dysphagia by 7%. The mean increase in lower esophageal sphincter pressure was 16.2 mm Hg. The total and intra-abdominal sphincter lengths increased an average of 1.5 and 1.4 cm, respectively.

Conclusions: These preliminary data suggest that laparoscopic Nissen fundoplication can be performed by experienced laparoscopic surgeons with excellent symptomatic and physiologic results and a morbidity rate comparable to conventional open antireflux procedures. Rigid patient selection criteria will help identify the patients most likely to benefit from reconstruction of a mechanically defective lower esophageal sphincter. Adherence to established operative principles for Nissen fundoplication will reduce the incidence of significant postfundoplication symptoms.
