[Advances in the treatment of gastroesophageal reflux. Intraoperative calibration of posterior fundoplication].
Posterior partial fundoplication can be as effective as total fundoplication in the long-term control of gastroesophageal reflux if the gastric fundus valve is encircled around the distal esophagus for no less than 270 degrees to obtain effective pressures in the newly built sphincter. In order to minimize the adverse effects, to reach constant results and to guarantee the reproducibility of the technique we have modified the 270 degrees posterior fundoplicatio (formerly described by Lind) according to the following principles: 1) the length of the gastric valve must be limited to 3 cm for each side of the esophagus; 2) the gastric valve must be fixed to the right and left side of the hiatal orifice by a single stitch; 3) the gastric valve must be calibrated with an intraoperative manometry, this allowing the standardization of the valve pressure to an average value of 35 mmHg by varying its wrapping angle; 4) the hiatal orifice must not be closed unless it is large enough for thoracic migration of the gastroplasty. Since 1984 to 1991 43 patients with proven gastroesophageal reflux not controlled by medical treatment were submitted to surgery. Twelve Nissen procedures (NP) and 31 posterior calibrated fundoplications (PCF) were performed; PCF seemed to be superior to NP in terms of postoperative mobility. After two years 20 patients treated with PCF were evaluated clinically, manometrically and by 24-hour pH monitoring. No dysphagia was reported; in two patients a pH-metric, asymptomatic relapse was observed, while one patient complained mild and occasional heartburn.(ABSTRACT TRUNCATED AT 250 WORDS)
