A proper delineation of the stricture anatomy is a prerequisite. A host of electrocautery and mechanical devices may be used, the most common being the use of needle knife, either standard or insulated tip. The technique entails radial incision and cutting off of the stenotic rim. Adjunctive therapies, to prevent re-stenosis, such as balloon dilatation, oral or intralesional steroids or argon plasma coagulation can be used. The common strictures where EIT has been successfully used are Schatzki's rings(SR) and anastomotic strictures(AS). Short segment strictures(< 1 cm) have been found to have the best outcome. When compared with routine balloon dilatation, EIT has equivalent results in treatment na?ve cases but better long term outcome in refractory cases. Anecdotal reports of its use in other types of strictures have been noted. Post procedure complications of EIT are mild and comparable to dilatation therapy. As of the current evidence, incisional therapy can be used for management of refractory AS and SR with relatively short stenosis(< 1 cm) with good safety profile and acceptable long term patency.展开更多

Due to anatomical challenges and a diverse bacterial flora in this area, surgical site infections (SSI) represent a common, debilitating and sometimes life-threatening complication. The INVIPS-Trial evaluates the role of Negative Pressure Wound Therapy (NPWT) on closed inguinal incisions in elective vascular surgery to prevent SSI and other wound complications. Methods: This randomized controlled trial (RCT) registered at ClinicalTrials.gov (Identifier: NCT01913132) compares the effects of a NPWT dressing (PICO, Smith & Nephew, UK) and the center’s standard wound dressing (Vitri Pad, ViTri Medical, Sweden) on postoperative wound complications, especially SSI. The study includes two distinct vascular procedures with different SSI risk profiles: endovascular aortic repair (EVAR) and open surgical approaches involving the common femoral artery (OPEN). Results: Four hundred ninety-five groin incisions in both treatment arms are anticipated to be included in the EVAR group and 147 inguinal incisions in both treatment arms in the OPEN group. Since a large percentage of inguinal vascular procedures in both groups but especially in the EVAR group are performed bilaterally, many patients can serve as their own control by randomly receiving NPWT on one and the standard dressing on the contralateral inguinal incision. Conclusions: This ongoing RCT attempts to elucidate the potential benefit of NPWT on closed inguinal incisions after different vascular procedures. Outcome and conclusions of this trial could have implications on postoperative wound care of patients in both vascular surgery and other surgical specialties.展开更多

文摘目的研究多个小切口联合负压治疗对毒蛇咬伤后肿胀消退和炎症反应的影响。方法选择2015年4月至2016年7月我科收治的毒蛇咬伤患者29例,其中男性18例,女性11例,年龄18~70岁,用随机数字法将研究对象分为对照组和观察组(注册号:Chi CTR-TRC-14004189)。对照组采用传统综合治疗,观察组行患肢近端皮肤多个小切口手术后予以负压吸引,同时采用传统综合治疗。分别在治疗前(0 h),治疗后6、12、24、48、72 h 6个时间点,测量并计算患肢近端、中部、远端肢体周径与健侧对应部位肢体周径差值,同时测血清IL-6和TNF-α浓度,记录平均住院时间。结果不同时间下测量的观察组与对照组肢体周径差值差异有统计学意义,观察组小于对照组(P<0.05);在不同测量时间下对照组与观察组IL-6与TNF-α浓度差异有统计学意义(P<0.05),观察组低于对照组;两组平均住院时间差异有统计学意义(P=0.001),观察组少于对照组[观察组(5.43±1.07)d,对照组(7.67±1.95)d]。结论毒蛇咬伤后在传统综合治疗基础上采用小切口负压治疗可有效控制肿胀,加速肿胀消退,减轻全身炎症反应,缩短住院时间。
