P-BN55 Results of the ARROW survey of anti-reflux practice in the UK
Abstract Background Gastro-oesophageal reflux disease (GORD) affects 10-20% of the population. Lifestyle modifications and medications such as proton pump inhibitors are generally well tolerated, however a variety of surgical and endoscopic interventions may be more suitable for well selected patients. Despite national guidelines and evidence from trials there is lack of consensus regarding the best approach to antireflux surgery (ARS). We designed a national audit (ARROW) to describe variation in UK clinical practice of ARS and adherence to clinical guidelines. Our audit was designed in two phases. First, a survey of national practice; Second, a prospective audit of adherence to available guidelines. Methods Survey questions were iteratively developed by the ARROW steering committee and an online tool was developed to gather survey responses and contact details for the audit phase. The final questionnaire consisted of 90 fields per surgeon and 57 fields per institution. Participants were enlisted through AUGIS, social media, personal contacts and the ROUX group of upper GI surgical trainees. The online tool was piloted in three centres. The protocol for the study was peer reviewed and published in Diseases of The Esophagus in January 2021 Results Survey responses were received from 151 surgeons at 57 institutions with a median of 40 cases annually and 4 surgeons/institution. Surgeons perform a median of 12(range 0-75) NHS cases and 6(range 0-75) private cases. 150/151 NHS surgeons perform some form of fundoplication for ARS, 4 surgeons perform LINX™, 4 STRETTA™ and 49 roux-en-y bypass for GORD. Fundoplication procedures performed in the UK include Nissen (111/151), Watson (39/151), Toupet (72/151) and Dor (61/151). 104 surgeons adjust the wrap performed according to clinical symptoms, manometry or both. 20/57 centres had no access to a benign MDT to discuss ARS. Conclusions ARS in the UK lacks standardised approaches that can be reliably compared and therefore improved most surgeons perform less than 20 cases a year. Our survey revealed differences in which investigations are considered mandatory, which procedures are available to whom and with what variations, and available resources to facilitate shared decision making for patients with GORD and ARS surgeons. Our audit phase (begun in April 2021) will establish current practice, compliance with clinical guidelines and inform improvement projects and randomised trials in the future.
