Esophageal submucosal tumor diagnosed with EBUS-guided transbronchial mediastinal cryobiopsy: A case report.

ABSTRACT: Cryobiopsy is advantageous for collecting larger specimens with minimum crushing compared to forceps biopsy and transbronchial needle aspiration (TBNA), but it has not been widely used for mediastinal tumors. In this report, a leiomyoma of the thoracic esophagus was diagnosed with endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-cryo). An asymptomatic 49-year-old woman had a 2.6-cm sized submucosal tumor (SMT) of the esophagus adjacent to the trachea and left main bronchus. EBUS-TBNA and EBUS-guided intranodal forceps biopsy were performed, followed by EBUS-cryo. The biopsy forceps could not be inserted into the tumor, but the cryoprobe was smoothly inserted. EBUS-TBNA could not obtain enough spindle-shaped tumor cells for immunohistochemical staining, but EBUS-cryo provided sufficient specimens for diagnosing the leiomyoma. Adding EBUS-cryo to EBUS-TBNA has recently been reported to achieve high diagnostic yields for lymphomas, uncommon tumors, and benign diseases. EBUS-cryo seems a valid diagnostic option for esophageal SMTs that are difficult to diagnose with needles and forceps.

Project description:BackgroundPatients with mediastinal lymph node enlargement (MLNE) are diagnosed depending on lymph node biopsy. Whereas, how to obtain larger tissue masses from mediastinal lymph nodes and improve the diagnostic yield of the disease remains to be investigated.ObjectivesAiming to assess the diagnostic value of endobronchial ultrasound-guided intranodal forceps biopsy via transbronchial laser photoablation (EBUS-IFB-TLP) in patients with MLNE.DesignA prospective, self-controlled study.MethodsThis study was conducted on 67 MLNE patients requiring a lymph node biopsy for diagnosis at the Henan Provincial People's Hospital and the Fuwai Central China Cardiovascular Hospital in China, from January 2020 to December 2022. Each patient underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA group) and EBUS-IFB-TLP (EBUS-IFB-TLP group) on the same mediastinal lymph node for biopsies. The operation time, diagnostic efficiency, and complication rates of the two biopsy methods were compared.ResultsThe number of diagnosed patients in the EBUS-IFB-TLP and the EBUS-TBNA groups was 65 (97.0%) and 57 (85.1%), respectively (p = 0.021). In the EBUS-IFB-TLP group, 28 cases (96.6%) were diagnosed with lung cancer and were classified into different epithelial types. In the EBUS-TBNA group, there were 27 cases (93.1%) diagnosed with lung cancer, of which 26 (89.7%) were classified into different epithelial types. There were 37 (97.4%) and 30 (78.9%) non-lung cancer patients diagnosed in the EBUS-IFB-TLP and EBUS-TBNA groups, respectively (p = 0.039), while 27 cases (96.4%) of sarcoidosis in the EBUS-IFB-TLP group and 20 cases (71.4%) of sarcoidosis in the EBUS-TBNA group were diagnosed (p = 0.016). The percentages of intraoperative mild to moderate bleeding complications were 23.9% (16/67) and 14.9% (10/67) in the EBUS-IFB-TLP and in the EBUS-TBNA groups, respectively (p = 0.109).ConclusionThis study demonstrated that EBUS-IFB-TLP could be a feasible and effective method in the diagnosis of patients with MLNE, presenting an analogous safety profile compared with EBUS-TBNA. Further studies are needed to verify the diagnostic performance of EBUS-IFB-TLP for MLNE.
