PURPOSE: Acute suppurative infection in soft tissues around the anorectal region and the radical excision of presacal tumor often results in cavity wound,which are characterized by large and deep surgical lesion.These cavity wound resulted in common postoperative problems including anal incontinence,delayed healing,long hospital stay,postoperative wound pain during dressing,and tremendous mental distress.Vacuum sealing drainage(VSD)technology is an arisen new approach in recent years to promote wound repair which has been widely used in all sorts of traumatic wound treatment and considered safe and reliable.Therefore,this study is to explore the safety and efficacy of VSD technology in management of cavity wound caused by anorectal disease.METHODS: Patients with cavity wound caused by anorectal disease were identified.If wound types extend below the subdermal layers of the skin and expose underlying structures such as tendons,muscle,and bone,they are referred to as “cavity wounds”.Demographics and clinical data,including predisposing factors,times of VSD used,surgical and postoperative management,were collected and analysed.RESULTS: Twelve eligible patients underwent VSD.Infection in all the case was under controlled.The demographic and clinical characteristics was listed in Table 1.The blood loss in patients was 50 ml(range,10~150ml).The mean postoperative visual analog scale score for pain was 3(range,1~4),2(range,1~4),3(range,2~6),1(range,0~3),and 1(range,0~2)at 12 h,days 1,2,3,and 7.No patients developed anal incontinence.The averaged healing time was 24.2 ± 7.6 days.CONCLUSIONS: The VSD technique seems to be beneficial to faliciate wound healing,relieve the postoperative pain,shorten hostpital stay.It appeared that VSD is a safe and effective technique in management of cavity wound caused by anorectal disease.
