Use of a gentamicin-impregnated collagen sheet (Collatamp(®) ) following implantation of a sacral nerve stimulator for faecal incontinence.

ABSTRACT

AIM: Gentamicin-impregnated collagen (Collatamp(®) ) is well described for the prevention of infection in surgery. This technical note describes its intraoperative use as a prophylactic measure to prevent infection following implantation of a sacral nerve stimulator for faecal incontinence. METHOD: Following implantation of the Interstim II Neurostimulator (Medtronic Neuromodulation, 710 Medtronic Parkway, Minneapolis, USA) in a subcutaneous pocket overlying the gluteal muscle, a single sheet of 10cm × 10cm gentamicin-impregnated collagen is placed within the wound covering the implant. The subcutaneous tissue and skin are then closed in separate layers. RESULTS: To date eight patients [median age 46.5 (30-59) years] have received prophylactic cover with gentamicin-impregnated collagen following permanent sacral nerve stimulator implantation. At a median interval of 89.5 (51-128) days, none of these patients developed a wound infection at the site of the neurostimulator implant. CONCLUSION: Gentamicin-impregnated collagen (Collatamp(®) ) used in the implantation of a sacral nerve stimulator may be a useful addition to the technique.
