Endoscopic retrograde cholangiopancreatography (ERCP) had become the favored method to access the pancreaticobiliary system because it is a safer and less invasive method compared to surgery. However, as with any procedure, ERCP comes with its own risks and potential complications. We present a unique case of a patient who underwent ERCP and developed necrotizing infection of the neck and a submandibular abscess. The patient is a 66-year-old female who presented to an outside hospital with complaint of right upper quadrant abdominal pain, workup of which revealed choledocholithiasis. ERCP was attempted; however, cannulation was unsuccessful. The patient was discharged home after the procedure, but within 48 h she presented to our institution complaining of left-sided neck pain, dysphagia, and drooling. CT of the neck revealed extensive gas and fluid collections at the left submandibular space. The patient was taken to the operating room for drainage of the left neck abscess. Drainage and irrigation of the abscess yielded Streptococcus mitis and Hemophilus parainfluenza. The rest of patient’s hospital course was uncomplicated, and she was discharged with appropriate follow-up. In the case of our patient, ERCP was complicated by a perforation of the hypopharynx. Pharyngeal perforation can be subclassified into supraglottic and infraglottic. The most frequent cause of perforations is due to increased pressure in an intrinsically weak anatomical region of the pharynx. Such perforations are commonly due to the advancement of the endotracheal tube or transthoracic echo probe, but can also be due to advancement of an endoscope.
