Transhiatal Chest Drainage After Hybrid Ivor Lewis Esophagectomy: Proof of Concept Study.

BACKGROUND

Intercostal pleural drainage is standard practice after transthoracic esophagectomy but has some drawbacks. We hypothesized that a transhiatal pleural drain introduced through the subxyphoid port site incision at laparoscopy can be as effective as the intercostal drainage and may enhance patient recovery.

PATIENTS AND METHODS

A proof of concept study was designed to assess a new method of pleural drainage in patients undergoing hybrid Ivor Lewis esophagectomy (laparoscopy and right thoracotomy). The main study aims were safety and efficacy of transhiatal pleural drainage with a 15 Fr Blake tube connected to a portable vacuum system. Pre- and postoperative data, mean duration, and total and daily output of drainage were recorded in an electronic database. Postoperative complications were scored according to the Dindo-Clavien classification.

RESULTS

Between June 2015 and December 2016, 50 of 63 consecutive patients met the criteria for inclusion in the study. No conversions from the portable vacuum system to underwater seal and suction occurred. There was no mortality. The overall morbidity rate was 40%. Two patients (4%) required reoperation for hemothorax and chylothorax, respectively. Percutaneous catheter drainage for residual pneumothorax was necessary in 2 patients (4%) on postoperative day 2. The mean duration of drainage was 7 days (interquartile range [IQR] = 2), and the total volume of drain output was 1580 mL (IQR = 880). No pleural effusion on chest X-ray was detected at the 3-month follow-up visit.

CONCLUSIONS

Transhiatal pleural drainage is safe and effective after hybrid Ivor Lewis esophagectomy and could replace the intercostal drain in selected patients.
