Description

<p>Unilateral or bilateral swelling from the parotid gland to the cervical region may occur after esophagogastroduodenoscopy (EGD). Of the seven cases we experienced, one case was bilateral and six were on the left side. In all cases, the onset of swelling occurred after peroral endoscopy, which had been performed without sedation in six patients and with sedation during double-balloon endoscopic retrograde cholangiopancreatography (DBERCP) in one patient. Two patients previously experienced similar swelling. Six patients felt no pain, and one patient felt slight pain at the swollen site. The swelling improved after about one hour in six patients, but disappeared after approximately 12 hours in one patient. Two patients underwent X-ray examination, but pooling of air could not be seen in either patient. One patient underwent computed tomography scan, and swelling of the parotid gland was diagnosed. Swelling from the parotid gland to the cervical region after EGD is not harmful and resolves spontaneously, but we believe that knowledge of the cases we report herein can be of importance to endoscopists.</p>
