Drain tube use in incisional hernia repair: a national survey.

purposeThere is debate regarding the use of drain tubes in incisional hernia repair. This has become topical in Australia, with a court judge suggesting that drain tubes are mandatory. There continues to be a lack of evidence to support generalised decision-making regarding the use of drain tubes.

methodsThe general surgeon membership of General Surgeons Australia (GSA) were surveyed regarding incisional hernia repair, their use of drains, and the decision-making behind their use.

resultsA total of 196 surgeons' survey responses were analysed. Most surgeons perform less than 20 incisional hernia repairs per year (78%), prefer an open approach (78%), and preferably perform a pre-peritoneal (sub-lay) repair (53%). There was a variety of approaches to leaving a drain, with the most common answer being "sometimes" (31.28%) and an equal number of surgeons claiming to always or never leaving a drain (11.79% each). There was also no consensus in the duration the drain should stay in, with most surgeons averaging less than 5 days. Interestingly, there was a range of views on the effects of drain tubes, with some surgeons believing drains decreased infections and more believing they increased infections. Most surgeons felt seromas were decreased, but there was increased post-operative pain. The majority of surgeons agreed there was no evidence to support their beliefs.

conclusionPlacement of drain tubes is not universally practiced by the general surgeons who participated in the survey. The lack of evidence is reflected by a varied approach to incisional hernia repair and the use of drain tubes.
