Editing Drains (section)

== Common indications ==

* Good indications:
** High probability of leakage of bile or pancreatic juice
** Established pus-containing abscess (non-collapsible)
** Not satisfied with source control
** Urine leak is expected
** High-risk UGI anatomosis
** Expected bleeding - but be very selective
* Specifically:
** Draining an anastomosis: J-P drain 
** Lap chole: Leave a drain only if worried about unsolved or potential bile leak. 14-16Fr Blakes likely connected to Bellovac.
** Appendix - almost never indicated, given source control has been achieved and peritoneal toilet has been performed
** Perf DU - not unless you are worried about the quality of repair
** Emergency left colon resection - unnecessary
** Generalised peritonitis - do not drain unless there is a defined rigid cavity, or a controlled fistula is required
