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.
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.
ObjectiveTo investigate the effect of vacuum sealing drainage (VSD) combined with autologous platelet-rich plasma gel (PRP) on postoperative wound infection and chronic poor wound healing, so as to provide more economical and safe treatment in clinic.MethodsThe patients with postoperative wound infection and chronic poor wound healing in the Second Affiliated Hospital of Nanchang University and Sixth Affiliated Hospital of Sun Yat-sen University from September 2018 to July 2019 were collected, then were divide into PRP+VSD group and VSD group according to treatment methods. The patients in the PRP+VSD group were filled with PRP and activator calcium thrombin following debridement, then covered with silver ion dressing and continuous VSD; in the VSD group were directly covered with silver ion dressing and then continuous VSD. The general situations of patients in the two groups during the process of replacing the VSD and the wound condition during dressing replacing were observed.ResultsThere were 100 patients in this study, 50 in the PRP+VSD group and 50 in the VSD group. There were no significant differences in the age, gender, body mass index, wound area before treatment, and wound infection type between the two groups (P>0.05). Compared with the VSD group, the PRP+VSD group had higher score of fresh granulation tissue coverage area (P<0.05), shorter wound closure time (P<0.05), shorter wound healing time (P<0.05), lower pain score (P<0.05), and less hospitalization expenses (P<0.05), lower rates of second debridement (P<0.05) and recurrent infection (P<0.05).ConclusionAutologous PRP combined with VSD in treatment of postoperative wound infection and chronic poor wound healing could shorten growth time of wound granulation tissue, promote rapid wound healing, reduce cost, and provide an economic, safe, and effective treatment method for clinical practice.
目的 探討急性闌尾炎手術后切口感染的相關因素。方法 觀察我院2002年5月至2007年5月期間收治的665例急性闌尾炎患者采用術前預防使用抗生素、術中保護切口、術后加強切口管理等處理后切口感染情況，并分析切口感染與闌尾炎的病程、手術時間、切口選擇、留置引流和病理類型之間的關系。結果 本組患者中32例發生切口感染，感染率為4.81% (32/665)，急性闌尾炎術后切口感染與性別無關（ P ＞ 0.05），與病程長短、切口選擇、手術時間、腹腔留置引流與否以及病理類型均有關（ P ＜ 0.01）。結論 病程長、手術時間久、炎癥較重的急性闌尾炎病例切口感染率較高； 做好圍手術期的處理，術中盡量保護切口可以降低切口感染率。
Objective To investigate factors for surgical difficulty and complications following closure of temporary ileostomy for rectal cancer. Methods The clinical data of 103 patients with low rectal cancer treated with closure of temporary ileostomy from January 2014 to July 2017 in the Northern Theater Command General Hospital were retrospectively analyzed. The associated factors of surgical difficulty and postoperative complications were identified by the univariate and multivariate logistic regression analyses. Results In this study, there were 11 (10.7%) patients with surgical difficulty (operation time >100 min) in the 103 patients. The multivariate logistic regression analysis showed that the history of previous abdominal surgery ［OR=5.272, 95% CI (1.325, 20.977), P=0.018］ and minimally invasive surgery ［OR=0.166, 95% CI (0.037, 0.758), P=0.020］ were the independent influencing factors of the difficulty of surgery. The complications following closure of temporary ileostomy included 16 (15.5%) patients with the incision infection, 5 (4.9%) patients with the intestinal obstruction, and 3 patients with the pulmonary infection (2.9%). The multivariate logistic regression analysis showed that the diabetes ［OR=4.855, 95% CI (1.133, 20.804), P=0.033］, operation time >100 min ［OR=11.914, 95% CI (2.247, 63.171), P=0.004］, and peristomal dermatitis ［OR=18.814, 95% CI (3.978, 88.988), P<0.001］ were the independent influencing factors for the incision infection. Conclusions History of previous abdominal surgery is main cause for difficulty of surgery and minimally invasive surgery can reduce difficulty of surgery. Diabetes mellitus, longer operation time, and peristomal dermatitis are main causes of postoperative incision infection.

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.
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.
