The subject underwent reshape balloon insertion procedure on (b)(6) 2017.Per md, he experienced difficulty and resistance while trying to advance the balloon through the pharnyx and esophagus.Md decided to remove the delivery catheter/balloon assembly to apply additional lubrication and then reinsert.As he retracted the deliver catheter, the balloon detached from the catheter, leaving the balloons in the posterior pharynx and across the upper esophageal sphincter (ues).Patient's o2 saturation levels dropped until md was able to retrieve the balloon using magill forceps.Md speculated that a ues spasm may have impeded retraction of the balloon.Due to the temporary airway compromise, patient was admitted to the hospital for observation on (b)(6) 2017 and was discharged in stable condition the next morning ((b)(6) 2017) with no further sequelae.
