手部复杂组织缺损的急诊显微外科修复

目的 探讨应用显微外科技术急诊一期修复手部复杂组织缺损的手术方法及临床效果，方法 自2000年1月至2005年8月，对手部复杂组织缺损的49例，应用再植、再造、游离皮瓣或组合皮瓣技术进行急诊一期修复重建，其中手部小组织块再植与再造21例，再植组合吻合血管的皮瓣移植15例，再植同时进行再造并组合皮瓣移植8例，多指组合再造联合皮瓣移植5例。吻合血管的游离皮瓣移植包括股前外侧皮瓣、背阔肌皮瓣、足背皮瓣、足内侧皮瓣及足底内侧皮瓣等。结果 除1例冉植手指坏死外，其余皮瓣及再植与再造手指全部成活。创口一期愈合45例，二期愈合4例。随访6个月～3年，手部功能及修复部位外形恢复良好，按中华医学会手外科学会上肢部分功能评定试用标准，优良率为85．7％．结论 应用显做外科技术修复手部复杂组织缺损具有疗程短、功能效果好的优点，根据缺损部位、范围以及术者的技术水平，在急诊再植与再造的同时组合不同的显微外科皮瓣或组织瓣进行一期修复，可获得理想的临床效果。

Emergency reparation and reconstruction for complicated tissue defects in hand

Objective To explore the operative methods and clinical outcomes in emergency or sube- mergency repair for the complicated tissue defects in hand in first stage applying microsurgical technique. Methods From Jan.,2000 to Aug.,2005,49 emergency cases of complicated hand tissue defects were re- paired in the first stage with replantation,reconstruction,free flaps,combined finger reconstruction and flap transplantation,including 21 cases in mini tissue mass replantation or reconstruction,15 cases in replantation combined with free flap transplantation,8 cases in replantation and reconstruction combined with free flap transplantation,5 cases in combined multiple digits reconstruction with free flap transplantation.The free flap transplantation included the anterolateral femoral flap,the latissimus dorsi myocutaneous flap,the dorsalis pe- dis flap,the media pedis flap and the instep flap.Results All the flaps,the replanted and reconstruceted finger survived uneventfully except for one replanted finger necrosis.45 cases healed in the first stage and the other 4 cases healed in the second stage.During a follow-up from 6 months to 3 years postoperatively,a satis- factory appearance and function of the reconstructed hand was achieved.The excellent and good rate was 85.7% assessed with provisional functional assessment criterion for upper limbs issued by Chinese Society of Hand Surgery.Conclusion The emergency or subemergency repair for the complicated tissue defects in hand has the advantage of short-term treatment and desirable functional outcome.The emergency replantation and reconstruction combined with various flaps or tissue mass can be applied to repair tissue defect in hand in the first stage according to the position and area of the defect along with the technique level of the surgeon, having been proved to achieve desirable clinical outcomes.And the key points leading to a successful operation is the correct treatment for the raw surface of the defects,suitable choice for various flaps,logical design of combination pattern and prevention and timely treatment for vessel crisis.
