Computed Tomography-guided Radiofrequency Ablation for Sub-diaphragm Hepatocellular Carcinoma: Safety and Efficacy of Inducing an Artificial Pneumothorax.
Acta medica Okayama, 2016Co-Authors: Hiroyasu Fujiwara, Yasuaki Arai, Hiroaki Ishii, Susumu KanazawaAbstract:We retrospectively evaluated the safety and efficacy of Artificial Pneumothorax induction to perform computed tomography (CT)-guided radiofrequency ablation (RFA) for sub-diaphragm hepatocellular carcinomas (HCCs). From June 2008 to October 2010 at our institution, 19 HCCs (16 patients) were treated using CT-guided RFA after Artificial Pneumothorax induction. A 23-G needle was inserted into the liver surface at a site of 2 connected pleurae without lung tissue. After a small amount of air was injected, the pleural space widened, creating a small Pneumothorax. Additional air was insufflated via a newly inserted 18-G cannula to raise the lung away from the planned puncture line for RFA. The electrode was then advanced transthoracically. Ablation was performed using a cool-tip electrode with manual impedance control mode. The injected air was then aspirated as much as possible. Artificial Pneumothorax was successfully induced in all cases. The average total volume of injected air in each case was 238ml. No Artificial Pneumothorax-related complication occurred; lung injury occurred in one case during RF electrode insertion. No local progression occurred during follow-up. Recurring HCCs were observed in eight patients. Artificial Pneumothorax induction is safe and effective for CT-guided RFA of sub-diaphragm HCCs, which are difficult to locate on US.

Technique for creation of Artificial Pneumothorax for pain relief during radiofrequency ablation of peripheral lung tumors: report of seven cases.
Journal of vascular and interventional radiology : JVIR, 2011Co-Authors: Takao Hiraki, Hideo Gobara, Kentaro Shibamoto, Hidefumi Mimura, Yuko Soda, Mayu Uka, Yoshihisa Masaoka, Shinichi Toyooka, Susumu KanazawaAbstract:Abstract This report describes seven cases in which a Pneumothorax was Artificially created for relief from severe pain that occurred during radiofrequency (RF) ablation of peripheral lung tumors. In this procedure, the multitined probe surrounding the lesion was advanced into the chest, displacing the tines and the peripheral tumor away from the parietal pleura and the chest wall and resulting in pain relief in one patient; in the remaining patients, an intravenous catheter was also introduced, followed by the administration of carbon dioxide (CO 2 ) into the space between the tumor and the parietal pleura. The pain decreased considerably immediately after this procedure. No complication related to the creation of the Artificial Pneumothorax was observed. Creation of an Artificial Pneumothorax is a safe and effective method for pain relief.

Artificial Pneumothorax for pain relief during microwave ablation of subpleural lung tumors
Indian Journal of Cancer, 2015Co-Authors: Xia Yang, K Zhang, Aimin Zheng, Guanghui Huang, Zhigang Wei, Jian Wang, Xiaoying HanAbstract:Background: When microwave ablation (MWA) is used for subpleural lesions, severe pain was the common side effect under the local anesthesia conditions during the procedure and postprocedure. To study the pain relief effect of Artificial Pneumothorax in the treatment of subpleural lung tumors with MWA. Materials and Methods: From February 2012 to October 2014, 37 patients with 40 subpleural lung tumors underwent MWA, including 17 patients of 19 sessions given Artificial Pneumothorax prior to MWA (group-I), and 20 patients of 21 sessions without Artificial Pneumothorax (group-II). Patient's pain assessment scores (10-point visual analog scale [VAS]) at during-procedure, 6, 12, 24, and 48 h after the MWA procedure and mean 24 h morphine dose were compared between the two groups. Complications of the Artificial Pneumothorax were also summarized. Results: Pain VAS were 0.53, 0.65, 1.00, 0.24, and 0.18 at during-procedure, 6, 12, 24, and 48 h for group-I and 5.53, 2.32, 2.82, 1.21, and 0.21 for group-II, respectively. Pain VAS in group I was significantly decreased at during-procedure, 6, 12, and 24 h after the MWA (P 0.05). The mean 24 h morphine dose was 5.00 mg in group-I and 12.63 mg in group-II (P = 0.000). “Artificial Pneumothorax” related complications occurred in two patients from group-I, including one pleural effusion and one minor hemoptysis. No patient in group-I and group-II died during the procedure or in 30 days after MWA. Conclusion: Artificial Pneumothorax is a safe and effective method for pain relief during MWA of subpleural lung tumors.

"Artificial Pneumothorax" related complications occurred in two patients from group-I, including one pleural effusion and one minor hemoptysis. No patient in group-I and group-II died during the procedure or in 30 days after MWA. Artificial Pneumothorax is a safe and effective method for pain relief during MWA of subpleural lung tumors.

Thoracoscopic resection of bulky thymoma assisted with Artificial Pneumothorax: A report of 19 consecutive cases
Oncology letters, 2016Co-Authors: Miao Zhang, Xuefeng Pan, Wang Heng, Wu Wenbin, Zhang HuiAbstract:The aim of the present study was to examine the feasibility and efficacy of thoracoscopic radical resection of large retrosternal thymoma using Artificial Pneumothorax. A retrospective analysis was performed on 19 patients with bulky thymoma who underwent thoracoscopic resection using Artificial Pneumothorax by CO2 insufflation. The operations were performed with unilateral or bilateral thoracic incisions via single lumen endotracheal intubation and two-lung ventilation. This approach provided excellent exposure of the thoracic cavity and reliable control of the neuro-vascular structures in the anterior mediastinum, which was of vital importance for the extended resection of malignant thymoma. The operation time was 140.0±51.4 min without conversion to thoracotomy or sternotomy. The pathological diagnosis was confirmed by immunohistochemistry, including 5 cases of thymus lipomyoma, 1 case of thymus hyperplasia, 1 case of thymus cyst, 2 cases of type AB thymoma, 4 cases of type B1 thymoma, 4 cases of type B3 thymoma, and 2 cases of thymic carcinoma. Furthermore, there were no complications such as recurrent laryngeal nerve injury, phrenic nerve injury, pulmonary infection or atelectasis, with a hospital stay of 5.0±3.0 days. In conclusion, the thoracoscopic resection of thymoma using Artificial Pneumothorax is a preferable approach, that may be considered for patients with bulky retrosternal tumors.
