APONTE, Raul et al. Intraoperative assessment of the distensibility of the gastroesophageal junction in antireflux fundoplication. Gen [online]. 2014, vol.68, n.1, pp.17-20. ISSN 0016-3503.

Introduction: The altered distensibility of the gastro esophageal junction (GEJ) is recognized as a primary pathophysiologic factor in the development of gastro esophageal reflux disease (GERD). The increase in GEJ distensibility allows reflux of large volumes of gastric contents into the esophagus, increases transient relaxations of the lower esophageal sphincter and increases the number of reflux and esophageal exposure to acid. Moreover, other pathologies with functional obstruction of the GEJ as achalasia have very little distensibility. Recently was reported that GEJ can be calibrated during surgery using balloon catheter, allowing real-time measurement of capacity, diameter and GEJ pressure during surgery. Objectives: To review the usefulness of the measurement of the distensibility of the GEJ as a predictor of success in laparoscopic fundoplication (LP) using Endoflip® commercial catheter, used intra-operatively in patients undergoing LP anti reflux surgery practicing measurements before and after plication. Material and Methods: The Toupet Fundoplication (TFP) was performed under standard technique, balloon distension measurements were taken, filling with 40 ml of 0.2% saline solution as specified by the manufacturer: a) after induction of anesthesia and once the pneumo peritoneum was stabilized b) After repairing the crura of the diaphragm and c) after the wrapping. Data was analyzed by students t P <0.05 and was considered significant. Results: A total of 9 patients (6 men), age average was 45.2 (32-72), all patients had previous functional and endoscopic studies and surgical indication existed, they all had a diagnosis of hiatal hernia, they all signed informed consent. No patient had postoperative complications. The Toupet Fundoplication (TFP) significantly reduced average GEJ distensibility to 40 ml of 52.8 to 29.8 mm2/mmHg mm2/mmHg (p = 0.0021, which represents a reduction of 43.5%). Conclusion: This method allows the gastro surgical team to make decisions on GEJ surgery in which the target value of distensibility can define the success of the surgery and avoid postoperative adverse events.
