Abstract： Objective To introduce the early experience of using vacuum-assisted closure （VAC） in the treatment of wound dehiscence after thoracic and cardiovascular surgery. Methods This report retrospective1y analyzed the clinical data of 12 patients who underwent VAC in the treatment of wound dehiscence after thoracic and cardiovascular surgery in the Affiliated Hospital of the Logistics University of CAPF between October 2010 and October 2011. There were 7 male patients and 5 female patients with their mean age of 64.3 years （ranging from 39 to 80 years）. All patients underwent operation via median sternotomy or lateral thoracic incision. All the wound dehiscence was deep to sternum or rib. After debridement of necrotic tissue, the wound surfaces were covered with VAC sponges, and intermittent negative pressure therapy was used. The VAC sponges were changed every 7-10 days. Results All the patients underwent an average of 2 times to change the VAC sponges during VAC treatment. After VAC treatment, the edema around the surgical wounds gradually disappeared, and the granulation tissue was refreshed. The overall conditions of all the patients were improved. The patients could leave their bed, walk in the ward, and look after themselves. Antibiotic treatment was no longer used. The residents checked up the negative pressure system every day to see whether it worked well. The patients were no longer afraid of changing dressing and pain every day. All the patients were healed, discharged from the hospital and followed up at outpatient department for a mean time of 7 months. Their wounds all healed well during follow-up. Conclusion VACsystem is easy to use. It can facilitate the healing of wound dehiscence quickly, decrease the inflammatory reaction of local wound and the body, and shorten the rehabilitation time. It’s also helpful to reduce the residents’ work load. It is recommended in the treatment of wound dehiscence after thoracic and cardiovascular surgery.
ObjectiveTo explore the surgical treatment of deep chest wall infection, improve the cure rate and reduce the recurrence rate.MethodsThe clinical data of 655 patients with deep chest wall infection treated in Yanda Hospital and Beijing Royal Integrative Medicine Hospital from June 2015 to June 2020 were retrospectively analyzed. There were 450 males and 205 females, aged 55.6±12.8 years. There were 8 patients with chest wall infection after tumor necrosis, 15 patients after radiotherapy and 632 patients after thoracotomy (612 patients after cardiovascular surgery and 20 patients after general thoracic surgery). Among them, 649 patients underwent debridement and reconstruction of chest wall defect with muscle flap.ResultsThe average operation time was 95±65 min, the average intraoperative blood loss was 180±100 mL, and the average postoperative hospital stay was 13±6 d. Of the 649 patients who underwent muscle flap reconstruction after debridement, 597 patients recovered within 2 weeks, and the primary wound healing rate was 94.4%. Twenty-three (3.5%) patients died. The median follow-up time was 25 (2-40) months. Among the remaining 632 patients, 20 recurred, with a recurrence rate of 3.1% (20/632).ConclusionPedicled muscle flap after thorough debridement of deep chest wall infection is one of the best methods to repair chest wall defect with pedicled muscle flap.
目的 分析胃肠外科手术切口感染的影响因素，为医院感染的防治提供理论依据。 方法 回顾性分析2010年12月－2012年12月764例行胃肠外科手术患者的临床资料，并用单因素χ2检验统计分析患者医院感染的危险因素。 结果 共有65例患者发生手术切口感染，其感染率为8.5%，且分离培养出合格菌株48株，阳性率73.8%，其中G−菌32株，占66.7%，G+菌16株，占33.3%。G−菌主要以大肠杆菌、变形杆菌、克雷伯杆菌和肠杆菌为主，分别占29.2%、18.8%、12.5%和6.2%；G+菌以肠球菌和表皮葡萄球菌为主，分别占22.9%和10.4%。单因素χ2检验显示年龄＞60岁、手术时间＞120 min、术中有输血、且有肿瘤病变的患者具有较高的切口感染发生率（P＜0.05）。 结论 胃肠外科手术切口感染的主要致病菌是G−杆菌，患者的年龄、手术时间、术中输血情况和疾病良恶性质是术后切口感染的高危因素，积极采取相应的预防措施有望减低其感染的发生率。
目的 探讨急性阑尾炎手术后切口感染的相关因素。方法 观察我院2002年5月至2007年5月期间收治的665例急性阑尾炎患者采用术前预防使用抗生素、术中保护切口、术后加强切口管理等处理后切口感染情况，并分析切口感染与阑尾炎的病程、手术时间、切口选择、留置引流和病理类型之间的关系。结果 本组患者中32例发生切口感染，感染率为4.81% (32/665)，急性阑尾炎术后切口感染与性别无关（ P ＞ 0.05），与病程长短、切口选择、手术时间、腹腔留置引流与否以及病理类型均有关（ P ＜ 0.01）。结论 病程长、手术时间久、炎症较重的急性阑尾炎病例切口感染率较高； 做好围手术期的处理，术中尽量保护切口可以降低切口感染率。
Objective To investigate the infection rate and observe the healing courses of the incision after gastrointestinal surgery which was managed by positioning extraperitoneal U-type latex drainage strip. Methods Two hundred patients after abdominal operation were divided into drainage group (n=97) and control group (n=103). Drainage group were treated with positioning extraperitoneal U-type latex drainage strip, while control group were treated with no latex drainage strip. The infection rate of incision, the mean time in hospital and mean time of incision healing were observed. Results The infection rate of drainage group was significantly lower than that of control group 〔7.22% (7/97) vs. 18.45% (19/103), P=0.024〕. The mean time in hospital and the mean time of incision healing in drainage group were significantly shorter than those in control group 〔(8.86±1.48) d vs. (14.12±2.63) d， P=0.000； (8.24±1.02) d vs. (12.32±3.47) d， P=0.000〕. Conclusion The infection rate and the healing course of incision of gastrointestinal surgery could be improved by positioning extraperitoneal U-type latex drainage strip.
Objective To evaluate outcomes of vacuum sealing drainage（VSD）for the treatment of wound infection after cardiac surgery.?Methods?We retrospectively analyzed clinical data of 70 patients（with valvular heart disease，congenital heart disease or coronary heart disease）who underwent cardiac surgery via mid-sternotomy and had postoperative wound infection from Jan. 2008 to Jan. 2012 in General Military Hospital of Guangzhou Command. According to different treatment strategy for wound infection, all the patients with wound infection （incision longer than 5 cm） were randomly divided into VSD group （n=35） and control group（n=35） by random number table，while VSD treatment was used for patients in VSD group and routine treatment was used for patients in control group. Treatment outcome，duration of wound infection, duration of antibiotic treatment and treatment cost were compared between the two groups.?Results?There was no in-hospital death in both groups. Wound exudate significantly decreased and fresh granulation tissue grew well in the wound in most VSD group patients after VSD treatment. The cure rate of VSD group was significantly higher than that of control group （94.3% vs. 60.0%，P＜0.05）. Duration of wound infection （12.9±3.4 d vs. 14.8±4.1 d；t=-2.094，P=0.040）and duration of antibiotic treatment （7.0±1.5 d vs. 8.3±1.9 d；t=-2.920，P=0.005） of VSD group were significantly shorter than those of control group. There was no statistical difference in treatment cost between the two groups. Fifteen patients in VSD group were followed up （42.9%） for 3 months with good wound healing, and 20 patients in VSD group were lost in follow-up.?Conclusion?VSD is effective for the treatment of wound infection after cardiac surgery with shortened treatment duration and similar treatment cost compared with routine treatment.
ObjectiveTo review the research on the reasons of unplanned reoperation (URP) for degenerative lumbar spine diseases, and to provide new ideas for improving the quality of surgery for degenerative lumbar spine diseases. Methods The literature about the URP of degenerative lumbar spine diseases at home and abroad in recent years was reviewed and analyzed. Results At present, the reasons for URP include surgical site infection (SSI), hematoma formation, cerebrospinal fluid leakage (CSFL), poor results of surgery, and implant complications. SSI and hematoma formation are the most common causes of URP, which happen in a short time after surgery; CSFL also occurs shortly after surgery but is relatively rare. Poor surgical results and implant complications occurred for a long time after surgery. Factors such as primary disease and surgical procedures have an important impact on the incidence of URP. ConclusionThe main reasons for URP are different in various periods after lumbar spine surgery. Interventions should be given to patients with high-risk URP, which thus can reduce the incidence of URP and improve the surgery quality and patients’ satisfaction.
