Atraumatic intracutaneous skin closure with self-made fishing line suture compared to commercial thread.
OBJECTIVE
The aim of this study was to prove, whether the intracutaneous skin closure with self made fishing line suture is equivalent to commercial sutures.


METHODS
It was a randomised blinded animal study.


METHODS
The study was performed in December 2002 at the Muhimbili University College of Health Sciences in Dar-es-salaam.


METHODS
Both German surgeons from Mannheim, and Tanzanian surgeons from Dar es salaam operated on nine one year old Tanzanian domestic sheep.


METHODS
108 standardised cutaneous wounds on the backs of the animals were closed by intracutaneous sutures either with self produced fishing line suture or a commercial nylon suture (Ethilon).


METHODS
The clinical and histological outcomes, as well as the costs of this self-made fishing line suture, with a commercial nylon thread were evaluated and compared.


RESULTS
There are no significant differences between the two sutures in histological or clinical findings, or in the reported ease of use by the surgeons. The cost of a self-produced atraumatic thread is US$ 0.12, less than one-twentieth of the cost of the commercial thread.


CONCLUSIONS
Self-made fishing nylon suture has characteristics and properties in sheep skin wounds comparable to commercial nylon suture. The advantage of the commercial thread is the guaranteed quality assurance. It is discussed whether this quality assurance justifies the large price difference, and whether the self-produced thread should be recommended to surgeons in countries where the costs of surgical material often remains an obstacle for life saving operations.
