Abstract
Background
Stenosis after sleeve gastrectomy (SG) is common though diagnostic criteria and predictors of treatment response is unknown. Endoluminal functional impedance planimetry (EndoFLIP) is a diagnostic tool for measuring lumen geometry. We aimed to use EndoFLIP to characterize SG stenosis.
Methods
We enrolled SG stenosis patients undergoing serial pneumatic dilations between May 2018 and November 2018. Outcomes of interest included pre- and post-dilation EndoFLIP measurements and post-dilation symptom response.
Results
We included 10 patients who underwent a mean of 1.8 ± 0.7 dilations. Pre-dilation EndoFLIP characteristics were similar for responders and non-responders. Responders had larger mean post-dilation diameter (19.9 ± 2.9 mm vs 13.1 ± 1.3 mm, p = 0.007) and DI (21.3 ± 1.0 mm2/Hg vs 4.0 ± 5.4 mm2/Hg, p = 0.04) than non-responders.
Conclusion
Our pilot study supports the use of EndoFLIP in the management of SG stenosis.
