Chylothorax: unusual complication after laparoscopic gastric banding.

Laparoscopic adjustable gastric banding is one of the most frequently performed bariatric procedures because of its low operative risk and morbidity. Postoperative chylothorax has never been reported following bariatric surgery. We present the case of a 41-year-old woman who developed a massive right chylothorax after a laparoscopic gastric banding, whose lymphogram showed thoracic duct disruption. Good outcome was achieved after thoracoscopy approach with duct ligation. Although rare, chylothorax is a severe complication, and surgeons must be aware of anatomic landmarks. Chyle leak could be under-diagnosed in postoperative uncomplicated pleural effusions.
