Anterior cervical spinal surgery can lead to various complications. We hereby present a case of two rare complications combined-pharyngo-oesophageal diverticulum and its perforation after cervical plate dislodgement. A 53-year old male patient presented with progressive dysphagia 18 years after anterior cervical spinal fusion with tricortical bone graft and custom-made plate at the C6/7 level. Oesophagography revealed a pharyngo-oesophageal diverticulum in front of the cervical plate. It was confirmed by subsequent oesophagoscopy, which also demonstrated a 3-cm longitudinal defect at the posterior wall of the diverticulum. During surgical exploration of the patient's neck, the plate was removed, the diverticulum was completely mobilized and excised, the oesophageal wall manually sutured and a cricopharyngeal myotomy performed. An oesophageal suture line failure was suspected postoperatively, but was not confirmed during reoperation. A year later, the patient has no dysphagia or any other symptoms.

Background: Thymic epithelial tumors are rare thoracic tumors for which pathological diagnosis is challenging due to the definition of multiple subtypes, tumor heterogeneity, and variations in interobserver reproducibility. In this study, we aimed at analyzing the quality of pathological reporting in line with the consistency between initial diagnosis and final diagnosis after expert review through a collaboration between the largest thoracic oncology center in Estonia, and one expert center in France. Methods: Hospital electronic database and pathology databases from the Tallinn North Estonia Medical Centre were searched for thymic and mediastinal tumors from 2010 to 2017. Pathology specimens were referred to the Pathology Department of the Lyon University hospital. Overall, 55 tissue specimens from 49 patients were included. Results: From pathology reports, tumor size, diagnosis, and invasion had been mentioned in ≥80% of cases, while resection status and staging were assessed in only 48% and 17% of cases, respectively. The initial diagnosis was consistent with that of the review in 60% of cases. Diagnostic concordance for thymoma subtypes was low (Cohen's kappa 0.34, 95% CI: 0.16-0.52). Overall, a major change in the management of 8 (16%) patients had to be made after pathological review: 3 patients had a normal thymus according to the reference centre, while thymoma B1 or B2 had been diagnosed locally; 5 additional patients had a final diagnosis of non-thymic tumor. Conclusions: Implementing structured pathology reports may help to decrease discrepancies in the diagnosis of thymic epithelial tumors. The development of expert networks is an opportunity to improve diagnosis and patient care, particularly in regard to rare cancers.

Left tracheal sleeve pneumonectomy is rare and challenging surgical procedure with high postoperative complication and mortality rates. We describe the least invasive single-stage surgical approach using uniportal video-assisted thoracoscopic surgery (VATS) currently successfully applied for a left centrally located bronchogenic carcinoma with tracheal involvement. This case shows how uniportal VATS can be effectively used in challenging cases for reducing invasiveness without compromising patient safety nor oncological principles of complete surgical resection.
