To determine whether laparoscopic anterior fundoplication gives the same degree of antireflux control as a total fundoplication, we analyzed a prospectively followed cohort of patients from randomized controlled trials of laparoscopic antireflux surgery. There were 167 patients who returned for routine esophageal pH studies within 6 months of surgery (123 laparoscopic total fundoplications and 44 anterior fundoplications). There was no difference in percentage time pH <4 between fundoplication groups, but the total number of reflux episodes was significantly different (total fundoplication, four reflux events vs. partial fundoplication, six reflux events; p = 0.03). It is difficult to believe that this difference is either biologically or clinically important. In patients with a second esophageal pH study more than 5 years later, both the percentage time pH <4 (0.1% total fundoplication vs. 2.7% partial fundoplication; p = 0.004) and total number of reflux episodes (three total fundoplication vs. 24 partial fundoplication; p = 0.002) were significantly different. However, the postoperative esophageal acid exposure was within the normal range for both total and partial fundoplication, so whether the statistical difference is clinically important, remains a moot point.enLaparoscopic fundoplicationGastro-esophageal refluxEsophageal pH monitoringRandomized controlled trialJournal article002008178810.1007/s11605-008-0486-y0002581128000082-s2.0-4884908563042569Myers, J.
