Abstract
AbstractObjectivesThe purpose of this study is to report a case of iatrogenic pharyngoesophageal diverticulum post‐anterior cervical discectomy and fusion (ACDF) surgery, its management and management of postoperative complications. We also did a thorough review of literature about iatrogenic pharyngoesophageal diverticulum which is a rarely encountered complication occurring after a commonly performed surgery; ACDF.MethodsHere we describe a case of iatrogenic pharyngoesophageal diverticulum post‐ACDF surgery. In this paper we also make comparisons to the 23 cases reported in the literature in terms of: presentations, clinical findings, management courses, and complications. This study was approved by the Institution Review Board of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. (Ref. no.: IRB‐2023‐01‐473). The reported subject provided written informed consent before initiation of this study.ResultsOur case is a 45‐year‐old male with a history of ACDF surgery 8 years ago. He presented with dysphagia and regurgitations which started 1 year after ACDF. He was labeled as a case of Zenker's diverticulum and underwent multiple failed open and endoscopic surgeries prior to presenting to us. Upon presenting to our center, barium swallow showed the pharyngoesophageal diverticulum. Patient definitive diagnosis of iatrogenic rather than Zenker's diverticulum was established intra‐operatively with esophagoscopy which revealed exposed hardware inside the diverticulum. He underwent open diverticulectomy and diverticulopexy. Postoperatively he developed pharyngocutanous fistula and right vocal fold palsy, both successfully managed conservatively.ConclusionIatrogenic Pharyngoesophageal diverticulum is a rare complication following ACDF, however prolonged dysphagia shall warrant further investigation by contrast studies. Open diverticulectomy with muscle reinforcement is a good management modality. Due to the complicated anatomy secondary to previous operations, we recommend conservative management for patients with postoperative pharyngocutaneous fistula.
