P3.02-011 - Evaluation of a New Chest Tube Management Using Digital Air Leak Monitoring after Lung Resection (ID 2440)
09:30 - 09:30 | Author(s): K. Otani
- Abstract
Background:
The use of digital drainage systems after thoracic surgery is becoming accepted as a safe method. The aim of this study was to assess the effectiveness of the digital drainage system versus traditional devices on chest tube removal and air leak duration after lung resection. We report the management of a digital drainage system in patients undergoing lung resection.
Methods:
This study is retrospective study of patients undergoing anatomical lung resection (segmentectomy, lobectomy, sleeve lobectomy, or bilobectomy).145 patients who underwent lung resections for lung cancer were evaluated. Chest tubes were removed when an air leak was not evident anymore and the drained fluid was less than 200 mL/day.
Results:
These series includes 140 lobectomies, 2 sleeve lobectomies, 1 bilobectomy and 2 anatomical segmentectomies. Patients who use digital drainage system had a significantly shorter air leak duration (0.9 versus 1.7 days; p=0.037), no significance of duration of chest tube placement (4.4 versus 5.5 days; p=0.112) and no significance of chest tube placement after the air leakage disappearance (3.5 versus 3.8 days; p=0.71).
Conclusion:
Patients managed with digital drainage system experienced a shorter duration of air leak compared with those managed with traditional devices. Digital devices appear to be safe and effective and may prove to be a useful tool in the management of lung resection.

P3.08-032 - Maximizing Use of Robot-Arms in the Robot-Assisted Thoracic Surgery (ID 875)
09:30 - 09:30 | Author(s): K. Otani
- Abstract
Background:
We have previously reported on the importance of appropriate robot-arm settings and replacement of instrument-ports in robot-assisted thoracic surgery. Because the thoracic cavity requires a large space to access all lesions in various areas of the thoracic cavity from the apex to the diaphragm and mediastinum and the chest wall. Moreover it can be difficult manipulate the da Vinci[® ]Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) using only arms No. 1 and No. 2 depending on the tumor location. In this report, we show how robot-arm No. 3 can be used with maximum effectiveness in the da Vinci[®]-assisted thoracic surgery.
Methods:
Robot-arm No. 3 of the da Vinci® Surgical System was usually positioned on the same side of arm No. 2, and sometimes it was used as an assistant arm to avoid conflict with other arms in our previous report. We describe new effective application of robot-arm No. 3 for the da Vinci S®-assisted thoracic surgery. A 62-year-old man had an anterior mediastinal tumor suspected to be non-invasive thymoma. Instead of arm No. 1, arm No. 3 was placed in the 6th intercostal in the mid-axillary line inserted from reverse the side, rotating it behind the body of the da Vinci® Surgical System.
Results:
Robotic surgery enables access to tumors located throughout in the thoracic cavity. The time required for the da Vinci S ® -setting was 12 minutes and the console-time (the da Vinci S ®working time) was 75 minutes. Thymectomy was performed successfully, and the amount of bleeding was 68 ml, and there were no complications. The pathological findings were thymoma, Masaoka stage II.
Conclusion:
Arm No. 3 has wider range of motion than other arms because it has one more additional joint. That is the reason why arm No. 3 enables good operability and ability to reach remote lesions, such as in the apex, diaphragm, or costophrenic angle. Moreover, between the space of the camera-arm and arm No. 3 make enough working space than using arm No. 1 to avoid conflict between arms. This use of the da Vinci S ® arms should be helpful in robotic procedures for thoracic surgeons in manipulating the da Vinci S ® instrument arms. Our recent experience has taught us that arm No. 3 is extremely useful when used as the main arm instead of arm No. 1. This idea should facilitate the da Vinci S®-assisted thoracic surgery procedures as a new effective application of robot-arm No. 3.
