Abstract
In a prospective, randomized, clinical trial, we compared a partial (180–200‡, Toupet) with a total fundoplication (360‡, Rossetti) in the surgical treatment of gastroesophageal reflux disease. Seventy-one patients entered the trial; 33 were allocated to a partial fundoplication and 38 to a 360‡ fundic wrap. Each patient was investigated prior to as well as 3 and/or 6 months after the operation, including an endoscopic and clinical assessment. Manometry was carried out via a triple lumen catheter and the pressure in the high pressure zone (HPZ) in the distal esophagus was measured as well as the length of the intraabdominal segment by a “station pull-through” technique. Acid exposure of the esophageal mucosa was evaluated by ambulatory 24-hour pH measurements. Acid exposure of the esophageal mucosa was “normalized” by the 2 operations. In addition, the length of the HPZ was increased to a “normal” level by both operations. The pressure of the HPZ was, however, “normalized” only in patients allocated to a Rossetti fundoplication, whereas patients operated on with a partial fundoplication had a significantly lower HPZ pressure (p<0.01). The clinical assessment revealed excellent results in both groups with no significant differences between the 2 operations except for a higher incidence of dysphagia at 3 months after a Rossetti fundoplication (p<0.01), which disappeared during the subsequent 3 months. Dans une étude clinique prospective, randomisée, nous avons comparé la plicature partielle de la grosse tubérosité (180–200‡, opération d'A. Toupet) et la plicature totale (opération de Nissen-Rossetti) dans le traitement chirurgical du reflux gastrooesophagien. Parmi les 71 patients inclus dans cette étude, 33 ont eu une plicature partielle et 38, une plicature totale. Chaque patient a eu un examen clinique complet et endoscopique avant son intervention, et 3 et 6 mois après. Tous les patients ont eu une manométrie par cathéter à trois lumières, une mesure de l'hyperpression de l'oesophage distal, ainsi que la celle de la longeur de l'oesophage intra-abdominal. Une pH-métrie a été effectuée pendant 24 heures en ambulatoire pour mesurer l'exposition “acide” de l'oesophage. L'exposition “acide” a été corrigée par les deux opérations. La pression du bas oesophage n'a été, par contre, que “normalisée” chez les patients ayant eu une plicature totale alors qu'elle a été nettement abaissée chez ceux ayant eu une fundoplicature partielle (pp<0.01). La valoración clínica reveló excelentes resultados en ambos grupos sin diferencia entre las 2 operaciones, excepto por una incidencia mayor de disfagia a los 3 meses después de la fundoplicación, una diferencia que desvaneció en los 3 meses siguientes.Keywords
