Routine abdominal drainage for uncomplicated liver resection.

The main reasons for inserting a drain after elective liver resections are (i) prevention of sub-phrenic or sub-hepatic fluid collection; (ii) identification and monitoring of post-operative bleeding; (iii) identification and drainage of any bile leak; and (iv) prevent the accumulation of ascitic fluid in cirrhotics. However, there are reports that drain use increases the complication rates.
