AIM: To apply intraoperative ultrasound (IO-US) for the first time using a laparascopic probe to detect malignancy-susceptible solitary pulmonary nodules (SPN) and assess macrovascularization using color-coded doppler sonography or power doppler. Description of technical feasibility. METHODS: Technical description on intrathoracic endoscopic ultrasound. A positive ethics vote from the local ethics committee and written patient consent were available. Intraoperative ultrasound was performed using a laparascopic probe (Lap 13-4cs, Mindray) on the T9 ultrasound machine (Mindray, China). B-scan was used to detect the SPN. Color-coded doppler sonography (CCS) and power doppler were used to assess macrovascularization. Primary end pointwas the description of the technical performance of the Io-US. Secondary endpoints were the functions of Io-US in characterizing SPN. RESULTS: Io-US was successfully applied using (n = 2) cases in video-assisted thoracic surgery. All SPN were successfully detected intraoperatively with the intrathoracically placed laparascopy probe using B-mode and examined using CCS or power Doppler (100%). Resection was sonography-guided with marking of the tumor area in all cases without complications. Histological workup revealed malignancy in both cases. CONCLUSION: Intrathoracic application of laparascopically guided Io-US was technically feasible. In addition to B-mode detection, Io-US using power doppler and color-coded doppler sonography provided initial evidence for characterization of SPN based on macrovascularization.
