Shoulder girdle abscess due to Streptococcus agalactiae complicating esophageal dilation.

Bacteremia can result very unusually in significant complications after esophageal dilation. Procedure-related mucosal trauma may be a determinant, whereas pathogenic bacteria primarily originate from the patient's oropharyngeal flora. We describe an unusual case of Streptococcus agalactiae bacteremia and shoulder girdle abscess complicating esophageal bougienage. Consideration of specific risk factors and use of scrupulous procedural technique are warranted and will likely reduce pyogenic sequelae.
