Unlabelled: It is unclear whether a partial or complete gastric fundoplication done laparoscopically will offer the best control of reflux with the fewest side effects. Prospective evaluation of laparoscopic Rosetti-Nissen (360) and Toupet (180) fundoplication was performed with assessment of clinical and manometric data.Methods: Patients with severe gastroesophageal reflux referred for surgical correction underwent preoperative motility and upper endoscopy. A Rosetti-Nissen or Toupet fundoplication was then performed laparoscopically. Short gastrics were not divided. No bougie was used in the Toupet, which was sutured intracorporeally. A 2-cm, loose, floppy wrap about a 50-Fr bougie was performed in the Nissen. Eleven patients underwent Rosetti-Nissen and 11 Toupet fundoplication. Mean ages, duration symptoms, weight, and baseline LES, were not different. Preop esophagitis grades were similar, as were Visick Scores and presence of dysphagia.Results: Visick scores at 6 months were better in the Toupet group than the Rosetti-Nissen (P = 0.07). Persistent Dysphagia in four, Gas-Bloat in two, and Odynophagia in one within the Rosetti-Nissen group accounted for the difference, and were not seen in Toupets. LES pressures differed significantly pre and postop (P < 0.001). The change in LES pressure was significantly different between Toupet and Rosetti-Nissen (chart). Seven patients had postop 24-h pH tests; all had no reflux. Three Rosettis have required revision to Toupet, with resolution of their symptoms.Conclusions: In patients with severe GERD, laparoscopic Toupet and Rosetti-Nissen control symptoms and esophageal pH similarly. LES pressures are higher postop in the Rosetti-Nissen. Dysphagia and gas-bloat are more prevalent in the Nissen group. Laparoscopic Toupet fundoplication may be superior to Rosetti-Nissen in reducing the frequency of side effects frequently associated with antireflux surgery, yet with equal control of reflux.
