Experience of 10 years in routine trans operative endoscopy and calibration in fundoplication due to gastroesophageal reflux disease

Background: Endoscopy and intraoperative calibration in fundoplication for gastroesophageal reflux disease (GERD), confirm an adequate technique avoiding postoperative failure. Intraoperative changes and morbidity in routine use are unknown.Methods: Retrospective study in a single center, data were taken primarily from electronic archive medical records. A total of 899 who underwent fundoplication surgery with endoscopy and/or routine intraoperative calibration due to GERD met the required criteria between 1 January 2010 and 31 December 2020. The primary objective was to identify the number of calibration and intraoperative endoscopy findings. Also, the morbidity associated with its routine use was analyzed.Results: Over a 10-year study period, the most frequent calibration in the Nissen Fundoplication was 60Fr in 472 cases (61.4 %). The most used calibration in Toupet Fundoplication was 60Fr in 26 cases (21.1%). Endoscopy was performed in 786 patients (71.38%), of which; 3 patients (0.3%) required changes, secondary to fundoplication rotation in 2 patients (0.2%) and redundant gastric fundus in 1 patient (0.1%).Conclusions: Routine intraoperative calibration and endoscopy achieved excellent results in 96.8% of fundoplication’s, ensuring adequate esophageal position and corroborating an adequate intraoperative technique; decreasing the rate of failures and immediate postoperative dysphagia
