Laparoscopic ‘physiological’ antireflux procedure: Preliminary results of a prospective symptomatic and objective study

Abstract

The ‘physiological’ antireflux procedure has been shown to be as effective as Nissen fundoplication in reflux control, but with a significant reduction in the incidence of mechanical complications. This technique was attempted laparoscopically in 26 patients in a prospective study involving independent symptomatic, manometric and pH assessment performed before operation and at a mean of 5.5 months after operation. The procedure was successfully completed laparoscopically in 23 (88 per cent) patients. Mean hospital stay was 3.8 days and mean time to return to work 1.8 weeks. There was neither mortality nor reoperation; 91 per cent of patients obtained symptomatic relief (82 per cent Visick grade 1). There was no gas-bloat or inability to belch or vomit. All 14 patients who underwent objective testing had a normal oesophageal pH profile, the mean percentage total time that pH < 4 falling from 11.0 to 1.1 (P < 0.001). Lower oesophageal sphincter characteristics, including relaxation, were similar to control values. These preliminary results suggest symptomatic and objective results comparable to those following open surgery, but with the benefits of a shorter hospital stay and time off work. In addition to a lower incidence of mechanical complications, the relative ease of performance of this procedure confers an additional advantage over Nissen fundoplication when performed laparoscopically.
