BackgroundLaparoscopic total fundoplication is considered the most effective surgical option for gastroesophageal reflux (GER) disease. Some authors assume that total fundoplication may expose the patient to delayed transit of the swallowed bolus and increased risk of dysphagia, particularly when peristaltic dysfunction is present. We undertook this study to evaluate by means of combined multichannel intraluminal impedance and esophageal manometry (MII-EM) the impact of fundoplication on esophageal physiology. An objective measurement of the influence of the total wrap on bolus transit may be helpful in refining the optimal antireflux wrap (ie, partial vs. total).MethodsIn this study, 25 consecutive patients who underwent laparoscopic Nissen-Rossetti fundoplication had MII-EM and combined 24-hour pH and multichannel intraluminal impedance (MII-pH) before and after the surgical procedure. All patients completed preoperative and postoperative symptom questionnaires. The following were calculated for liquid and viscous deglutition lower esophageal sphincter pressure and relaxation, distal esophageal amplitude, the number of complete esophageal bolus transits and the mean total bolus transit time. The acid and nonacid GER episodes were calculated by MII-pH with the patient in both upright and recumbent positions.ResultsThe postoperative MII-EM showed an increased lower esophageal sphincter pressure (P < 0.05), whereas lower esophageal sphincter relaxation and distal esophageal amplitude did not change after surgery (P = NS). Complete esophageal bolus transits and bolus transit time did not change for liquid swallows (P = NS), but was more rapid for viscous after surgery (P < 0.05). Twenty-four hour pH monitoring confirmed the postoperative reduction of both acid and nonacid reflux (P < 0.05).ConclusionsLaparoscopic Nissen-Rossetti is effective in controlling both acid and nonacid GER without impairment of esophageal function. Appropriate preoperative investigation, meticulous patient selection and correct surgical technique are extremely important in securing good results.
