Pleural drainage after transthoracic esophagectomy: experience with a vacuum system.

Conventional pleural cavity drainage after esophagectomy involves one to two large-bore drainage tubes connected to underwater bottles. The purpose of this study is to evaluate the use of a small mobile vacuum drainage system. Out of 173 patients who underwent transthoracic esophagectomy, 167 (97%) had the vacuum drain successfully placed at the end of the operation. Of those, use of the vacuum drain was uneventful for 131 until its removal (78%). Air leaks necessitating connection to underwater drainage occurred in 34 patients (20%), but in 26 of them this was only temporary. Overall success was therefore achieved in 157 patients (94%). Median in-situ placement of the vacuum drain was 4 days, and 85% of patients had their drains removed by the seventh postoperative day. The presence of lung adhesions significantly increased the need for underwater drainage. Postoperative outcomes were no different from a historical cohort with conventional underwater drainage. No drain-related complications were reported. The vacuum drain is an alternative to the conventional, large-bore, chest tube system after transthoracic esophagectomy.
