Prospective randomized trial comparing Nissen to Nissen-Rossetti technique for laparoscopic fundoplication

Results: Division of the SGV resulted in a significant increase of the operating time (P <0.0001). The operation abolished reflux in both groups. Also, both types of Nissen fundoplication significantly increased the amplitude of peristalsis at distal esophagus (division group: from 56 ± 20 mm Hg to 64 ± 25 mm Hg, P = 0.01; nondivision group: from 65 ± 27 mm Hg to 75 ± 26 mm Hg, P <0.001) and the lower esophageal sphincter pressure (division group: from 16 ± 10 mm Hg to 24 ± 7 mm Hg, P <0.001; nondivision group: from 22 ± 8 mm Hg to 28 ± 5 mm Hg, P <0.001). No differences in the incidence of postoperative severe dysphagia (division group: 5 of 24; nondivision group: 3 of 32) and overall esophageal transit were accounted between groups. However, division of the SGV was associated with a significant increased incidence of gas-bloating syndrome (division group, 13 of 24, versus nondivision group, 9 of 32, P = 0.02).
