PS01.007: THE ROLE OF HIGH RESOLUTION MANOMETRY AFTER TOUPET-FUNDOPLICATION: COMPARING THE RESULTS WITH THE SYMPTOMS REMAINED 6 MONTHS AFTER SURGERY

Abstract Background Fundoplication is a well accepted method in treatment of gastro-esophageal reflux disease. High Resolution Manometry (HRM) is essential in diagnosis of functional esophageal diseases. The aim of our study was to find the place and value of HRM after 6 months of Toupet-fundoplication, and find correlation in symptoms remained, if any. Methods In 2016–2017 98 Toupet-fundoplications were performed by single surgeon. Surgeries were after HRM, EGD and pre-operative reflux symptom questionnaire performed in our Esophageal Center. Six months after surgery EGD, HRM and post-operative symptom questionnaire was planned to manage in each patients. Results Until Feb/01/2018 74/98 patients were more than 6 months after their operation. 72/74 patients completed the questionnaire and the EGD as well. 28/72 patients absolved HRM also. 25/28 patients had no complains and pre-operative symptoms relieved completely requiring neither PPI nor H2 blockers. 2/28 patients had gastric emptying problems, and 1/28 had moderate reflux associated symptom. Compared to that 22/28 patients HRM verified abnormal values mostly in DCI, however these 22 patients were asymptomatic. It has to be mentioned that DCI was better pre-operatively than post-operatively in 12 out of 22 cases. Conclusion Post-operative HRM can qualify and describe the wrap objectively (its location and basic pressure) however the latest Chicago-criteria was not developed for after-surgery states. We can conclude that post-operative routine HRM can mislead the physician, has importance only in patients with significant complains. Disclosure All authors have declared no conflicts of interest.
