Combined cumulative sum (CUSUM) and chronological environmental analysis as a tool to improve the learning environment for linear-probe endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) trainees: a pilot study

Objective: The ProCore ultrasound biopsy needle, used primarily to obtain intra-abdominal tissue core biopsies, has not been widely used for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this pilot study we evaluated the utility of the ProCore needle for sampling mediastinal or hilar lymph nodes during EBUS-TBNA. Design: Thirty-two patients were identified using both ProCore and conventional fine-needle aspiration (FNA) needles for sampling mediastinal or hilar lymph nodes (the study group). Another 33 patients underwent EBUS-TBNA using an FNA needle only (the control group). Specimen satisfactory rates were compared between the study and control groups. Aspirate smears and cell blocks were evaluated for the cellularity of lesional cells and bronchial contamination in a subset of patients in the study group. Results: Overall, the ProCore needle did not show additive value to specimen adequacy when comparing the satisfactory rates of the study and control groups (94 vs. 89%). The ProCore needle also did not procure significantly more lesional cells than the FNA needle. Conclusion: Our experience shows that the ProCore needle does not provide additive value when performing an FNA of mediastinal or hilar lymph nodes. The evaluation of more cases with this new technique is necessary to better determine the clinical utility of using ProCore during EBUS-TBNA.

We report a case of a 68-year-old gentleman, found to have a right hilar soft tissue mass whilst undergoing CT staging for prostate cancer. MRI imaging showed a heterogenous, enhancing solid mass without evidence of fat content. A linear probe endobronchial ultrasound-guided transbronchial needle aspiration was performed using a 19G needle. This confirmed the diagnosis of a benign chondroid hamartoma, avoiding the need for more invasive surgical biopsy.

Acute Pericarditis

A 27-year-old man was diagnosed with inflammatory myofibroblastic tumor, and multiple lymph node and subcutaneous metastases. After several administrations of anti-tumor therapy, he underwent mediastinal lymph node biopsy using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to confirm tumor relapse. Five weeks later, he complained of chest pain, then rapidly developed shock due to acute pericarditis. Although he was treated with antibiotics for anaerobic bacterial infection and cardiac drainage, mediastinal lymph node abscess and pericarditis did not improve. After the surgical procedure, his physical condition dramatically improved and he was treated with another molecularly targeted therapy. Pericarditis associated with EBUS-TBNA is extremely rare. In this case, salvage was achieved by surgical drainage of the lymph node abscess and pericarditis, and long survival was obtained with further administration of anti-tumor treatment.
