Objective:
The implementation of leech therapy for surgical flaps is not always logistically easy or comfortable for patients or healthcare providers. We examine different methods of placing sutures in the medicinal leech, Hirudo medicinalis, to make the implementation of leech therapy easier.
Methods:
Sixteen leeches were randomly divided into 3 groups: a control group, a deep anchoring suture group, and a superficial anchoring suture group. The leeches were observed to determine if either of these methods had an adverse effect on survival compared with the control group.
Results:
No difference in survival time was observed across the different groups.
Conclusion:
The placement of anchoring sutures in leeches can ease the implementation of leech therapy by allowing for greater control of the leeches and thus increased patient comfort.
