Full text available on request.Abstract
The OAGB is a bariatric procedure, which is frequently used in patients with morbid obesity. However the procedure still raises concerns regarding the high incidence of postoperative bile reflux, which has been associated with the possibility of developing (pre)cancerous lesions in the stomach or oesophagus. Therefore gastroscopies are performed with a low threshold to monitor the development of such lesions. Until now there is no consensus regarding the extent to which a gastroscopy should be performed in patients with bile reflux after OAGB. This research aims to give more insight in the extent to which gastroscopic findings lead to changes in the treatment of the patient, also taking the indication and patient-related factors into account. In this single-center retrospective cohort study of patients that underwent an OAGB at CON in 2019 and 2020 and that have had a gastroscopy since then. The study focused on the extent to which a gastroscopy caused a change in treatment and which patient-related factors could be predictive of a higher chance of changes in treatment. 82 patients were included, in which a total of 100 gastroscopies were performed. The incidence of postoperative bile reflux was 48%. There was no significant outcome of any variable when analyzing the predictive value. In conclusion, this study shows gastroscopies are performed to too great an extent. However, it remains undecided which gastroscopies are performed justly and which should be omitted.
