Safety and feasibility of oesophageal ultrasound for the work-up of thoracic malignancy in patients with respiratory impairment.

ABSTRACT: Biopsying lung tumours with endobronchial access in patients with respiratory impairment is challenging. However, fine needle aspiration with the endobronchial ultrasound-endoscope via the oesophagus (EUS-B-FNA) makes it possible to obtain tissue samples without entering the airways. Safety of EUS-B-FNA in these patients has not earlier been investigated prospectively. Therefore, this study aimed at assessing feasibility and safety of EUS-B-FNA from centrally located tumours suspected of thoracic malignancy in patients with respiratory insufficiency. The study is a prospective observational study. Patients with indication of EUS-B-FNA of centrally located tumours and respiratory impairment defined as modified Medical Research Council (mMRC) dyspnoea scale score of ≥3, saturation ≤90% or need of continuous oxygen supply were included prospectively in three centres. Any adverse events (AEs) were recorded during procedure and 1-hour recovery. AEs were defined as hypoxemia (saturation <90% or need for increased oxygen supply) or any kind of events needing intervention. Late procedure-related events were recorded during 30-day follow-up. Between April 1, 2020 and January 30, 2021, 16 patients were included. No severe AEs (SAEs) occurred, but AEs were seen in 50% (n=8) and 13% (n=2) of the patients during procedure and recovery respectively. AEs included hypoxemia corrected with increased oxygen supply and in two cases reversal of sedation. Late procedure-related events were seen in 13% (n=2) and included prolonged need of oxygen and one infection treated with oral antibiotics. In this cohort, EUS-B-FNA of centrally located tumours was safe and feasible in patients with respiratory impairment, when examined in the bronchoscopy suite. A variety of mostly mild and manageable complications may occur, a few even up to 30 days post-procedure.

Project description:Background and objectiveThe measurement of portal venous pressure (PVP) has been extensively studied, primarily through indirect methods. However, the potential of ultrasound-guided percutaneous transhepatic PVP measurement as a direct method has been largely unexplored. This study aimed to investigate the accuracy, safety, and feasibility of this approach.MethodsIn vitro, the experiment aimed to select a needle that could accurately transmit pressure, had a small inner diameter and was suitable for liver puncture, and performed on 20 healthy New Zealand white rabbits. An ultrasound-guided percutaneous transhepatic portal vein puncture was undertaken to measure PVP. Additionally, free hepatic venous pressure (FHVP) and wedged hepatic venous pressure (WHVP) were measured under digital subtraction angiography (DSA). The correlation between the two methods was assessed. Enroll study participants from October 18, 2023 to November 11, 2023 with written informed consent. Five patients were measured the PVP under ultrasound guidance before surgery to determine the feasibility of this measurement method.ResultsThere was no significant difference in the results obtained using 9 different types of needles (P > 0.05). This demonstrated a great repeatability (P < 0.05). The 22G chiba needle with small inner diameter, allowing for accurate pressure transmission and suitable for liver puncture, was utilized for percutaneous transhepatic PVP measurement. There were positive correlations between PVP and HVPG (r = 0.881), PVP and WHVP (r = 0.709), HVPG and WHVP (r = 0.729), IVCP and FHVP (r = 0.572). The PVP was accurately and safely measured in 5 patients with segmental hepatectomy. No complications could be identified during postoperative ultrasound.ConclusionPercutaneous transhepatic portal venous puncture under ultrasound guidance is accurate, safe and feasible to measure portal venous pressure.Clinical trial registration numberThis study has been registered in the Chinese Clinical Trial Registry with registration number ChiCTR2300076751.
