摘要

We report an unexpected, previously unreported complicationof Bravo pH capsule dislodgement. During BravopH testing of a 44-year-old man with gastroesophagealreflux disease, we were unable to endoscopicallyvisualize the capsule attached to the esophageal wallafter deployment. After multiple attempts to detect thecapsule, it was visualized in the left pyriform sinus. Asthere was significant risk for pulmonary dislodgement,ENT and pulmonary physicians were immediatelyconsulted to review options for safe removal. Ultimately,ENT successfully retrieved the capsule with a foreignbody removal forceps. The Bravo pH test is generallya well-tolerated diagnostic tool used to confirm thepresence of abnormal esophageal acid reflux. While fewcomplications have been reported, technical difficultiescan occur, including poor data reception, misplacement,and early dislodgement. Rarely, more serious complicationscan occur, ranging from esophageal wall traumato capsule aspiration. Gastroenterologists performingthis procedure should be aware of the low, but nontrivial,risk of complications.
