This study evaluates the use of acellular dermal matrix (ADM) in conjunction with negative pressure wound therapy (NPWT) and delayed split-thickness skin graft (STSG) application as an alternative to free tissue transfer for defect coverage of the penile shaft. Five patients with genital lymphedema and one with penile skin deficiency underwent penile shaft reconstruction with a two-stage surgical procedure. The first procedure aimed to the correction of skin defect and to neodermis regeneration through the use of an ADM (Integra®, Integra Lifesciences Corp., Plainsboro, NJ, USA) and NPWT. The second procedure 3 weeks later aimed to the covering of the skin defect with an unmeshed STSG. Both the Integra and skin graft showed completely taking at 7 days postop. No major complications occurred. At 6 months grafts gained sufficient elasticity to allow the sliding of the epidermis over the dermal layer, similarly the physiological penile shaft skin. Our results suggest that combined therapy might be an alternative to free tissue transfer for defect coverage of the penile shaft, leading to a good esthetic result, an optimal shaft coverage and providing adequate extensibility during erections. For best results we advise that in these cases urologists should collaborate with plastic surgeons.
本研究评估了脱细胞真皮基质 (ADM) 与负压伤口治疗 (NPWT) 和延迟性刃厚皮片移植 (STSG) 联合应用作为阴茎干缺损覆盖的游离组织转移替代方法。5 例生殖器淋巴水肿患者和 1 例阴茎皮肤缺损患者接受了阴茎干重建的两阶段手术。第一阶段的目的是通过使用 ADM(Integra®,Integra Lifesciences Corp.,Plainsboro,NJ,USA)和 NPWT 来纠正皮肤缺损和新生真皮。3 周后的第二阶段旨在使用非网眼 STSG 覆盖皮肤缺损。Integra 和皮片均在术后 7 天完全成活。没有发生重大并发症。6 个月时,移植物获得了足够的弹性,使表皮能够在真皮层上滑动,类似于生理阴茎干皮肤。我们的结果表明,联合治疗可能是阴茎干缺损覆盖的游离组织转移的替代方法,可获得良好的美学效果、最佳的阴茎干覆盖,并在勃起时提供足够的伸展性。为了获得最佳效果,我们建议在这些情况下泌尿科医生应与整形外科医生合作。
