Laparoscopic antireflux surgery: comparative study of Nissen, Nissen-Rossetti, and Toupet fundoplication. Société Française de Chirurgie Laparoscopique.

BACKGROUND: The aim of this retrospective study was to compare the results of Nissen, Nissen-Rossetti, and Toupet laparoscopic fundoplication in terms of gastroesophageal reflux disease (GERD). METHODS: From 1992 to 1996, 1,470 laparoscopic fundoplications were performed using one of three procedures: Nissen (n = 655), Nissen-Rossetti (n = 423), and Toupet (n = 392). Preoperative checkup included esophagogastroduodenoscopy in 1,437 patients (97. 7%), esophageal manometry in 934 patients (63.5%), and 24-h pH-metry in 799 patients (54.3%). The results were estimated at 1 month, 3 months, and 2 years. Patients unable to visit the hospital center were contacted by telephone. RESULTS: The three groups were quite similar regarding demographic data such as age, gender, preoperative clinical symptoms, and duration of GERD. One death (0.07%) occurred. At 3 months, there were no differences among the three groups concerning conversion, morbidity, dysphagia, early reintervention, or postoperative length of stay. The length of surgery was more important in the Toupet procedure. In the Nissen group, there were fewer Visick grade I patients but more Visick grade III patients. At 2 years, the recurrence and reintervention rates were similar. The overall residual severe dysphagia rate was 0.35% (n = 5). In the Nissen group, there were fewer Visick grade I patients but more in Visick grade II patients. There was no difference in Visick grade III and IV among the groups. More than 90% of the patients were satisfied (Visick I + Visick II), with no significant difference among the three groups. CONCLUSIONS: The results of this study do not differ significantly from the data reported in the literature, suggesting such surgical techniques are effective and well tolerated, and that both can be properly used in the treatment of GERD.

[Laparoscopic fundoplication for gastro-esophageal reflux. Multicenter study of 1,470 cases].

STUDY AIM: The aim of this multicenter retrospective study was to evaluate the immediate and 2-year results of the laparoscopic fundoplication for gastroesophageal reflux disease (GERD). PATIENTS AND METHODS: From 1992 to 1996, 1,470 laparoscopic fundoplications were performed for symptomatic GERD. Preoperative workup included upper GI tract endoscopy in 1,437 patients (97.7%), 24-hour pHmetry in 799 patients (54.3%) and esophageal manometry in 934 patients (63.5%). Four procedures were performed: Nissen, Nissen-Rossetti, Toupet and Toupet with cardiopexy. The results were estimated at 1 month and 3 months. The patients were examined or called 2 years after surgery in order to evaluate the functional results with Visick classification. RESULTS: Mean length of hospital stay was 4.6 days (range 2-48 days). Morbidity and mortality rates were 3.2% (47 patients) and 0.07% (1 patient) respectively. Conversion rate into laparotomy was 6.5% (96 patients). After 3 months, 87 patients (5.9%) had severe dysphagia and 91.9% of the patients were satisfied. At 2 years, 78 patients (5.6%) had a clinical recurrence. Five patients (0.35%) had a persistent dysphagia, 90 patients (6.5%) had secondary side effects; 38 patients had been reoperated; 92.7% of the patients were satisfied. There was no significant difference between the results of the four procedures, 3 months and 2 years after surgery. CONCLUSIONS: Laparoscopic fundoplication for treatment of GERD is a safe and effective procedure; 92.7% of the patients were satisfied 2 years after surgery.

[Anatomical study of the intramural esophageal branches of the vagus nerve with gastric distribution in man].

Thoraco-abdominal oseophagus was removed in continuity with the stomach during autopsy of 30 patients--two patients had undergone troncular vagotomy and pyloroplasty, the other 28 had not been operated on. In 22 cases (including the 2 which had undergone vagotomy) one or more branches of the thoracic vagus nerve existed. These branches (intramural nerves) reached the stomach after passing for 1.5 to 10 cm between the two muscular layers (of the oesophagus). They originated more often from the anterior (18) than from the posterior vagus nerve (-6). Intramural nerves are spared during abdominal vagotomy: are they the cause of some therapeutic failures of vagotomy?

Morbidity of laparoscopic fundoplication for gastroesophageal reflux: a retrospective study about 1470 patients.

BACKGROUND/AIMS: The aim of this retrospective study was to report and quantify the immediate and 3-year complications after laparoscopic anti-reflux surgery in order to understand the mechanism. METHODOLOGY: From 1992 to 1996, 1470 laparoscopic fundoplications were performed for symptomatic gastroesophageal reflux disease. Preoperative checkup included upper gastrointestinal tract endoscopy in 1437 patients (97.7%), esophageal manometry in 934 patients (63.5%), and 24-hour pHmetry in 799 patients (54.3%). Three procedures were performed: Nissen (n = 655), Nissen-Rossetti (n = 423), and Toupet (n = 392). The results were estimated at 1 and 3 months; thereafter they were evaluated at 3 years. Patients unable to return to the hospital center were contacted by telephone. RESULTS: Mean length of hospital stay was 4.6 days (range: 2-48 days). The preoperative complication rate was 2.1% (n = 31). The postoperative morbidity and mortality rates were 2.9% (43 patients) and 0.07% (1 patient), respectively. Conversion rate to laparotomy was 6.5% (96 patients). At 3 months, 87 patients (5.9%) had invalid dysphagia but there was no difference between the 3 procedures. Twelve patients have been reoperated (0.8%). At 3 years, 78 patients (5.6%) presented a clinical recurrence. The rate of dysphagia was 0.35%, and 38 patients were reoperated. CONCLUSIONS: Laparoscopic fundoplication is safe and effective with a low morbidity and mortality rate if junior surgeons commenced this procedure under the direct supervision of an experienced surgeon. Despite the advantage of this technique, we believe that indications for surgical management remain unchanged in the laparoscopic era.
