Abstract

BACKGROUND: The methods for managing chest drainage tubes during the postoperative period differ among thoracic surgeons and, as a result, the optimal method remains controversial. PATIENTS AND METHODS: We reviewed 170 consecutive patients undergoing a pulmonary lobectomy for either primary lung cancer or metastatic lung cancer from January 1998 to December 2002. After the operation, the chest drainage tube was placed on a suction pump with a negative pressure of -10 cmH(2)O in 120 patients before 2001, while such drainage tubes were kept on water seal in 47 cases mainly since 2001. RESULTS: Regarding the preoperative and postoperative variables, postoperative air leak as well as the video-assisted thoracic surgery (VATS) procedure were more frequently observed in the water seal group than in the suction group (p=0.01580, p<0.001, respectively). In comparing these different populations, each Kaplan-Meier curve, which presented the duration of the postoperative air leak seemed to be similar between the two methods. CONCLUSION: These observations suggest that applying chest tubes on water seal seems to be an effective method for preventing postoperative air leak in clinical practice. However, a prospective randomized trial using a larger series of patients is warranted for this subject.
