目的 观察运用两种不同缝线固定修补材料对疝修补术后的复发、切口感染、慢性疼痛等并发症发生情况。方法 对2008年4月至2010年4月期间笔者所在科室收治的250例腹股沟疝患者行无张力疝修补手术时,采用多股丝线或可吸收合成缝线固定修补材料进行前瞻性对比研究。结果 2组患者术后疝复发、切口感染和切口疼痛(包括慢性疼痛)发生率间的差异均无统计学意义(P>0.05)。结论 腹股沟疝无张力修补术后的复发、切口感染、慢性疼痛等并发症的发生与缝线选择无关。术者的操作技巧、严格的无菌操作原则、彻底止血以及组织损伤小才是防止术后感染、慢性疼痛等并发症发生的重要因素。
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 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。
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.
Objective To introduce the experience about thereconstruction of median sternotomy wound dehiscence. Methods From February 2002 to October 2004, 10 patients with median sternotomy wound dehiscence due to coronary artery revascularization were treated. There were 7 males and 3 females, aging from 68 to 76 years. The sizes of defects ranged from3 cm×5 cm to 5 cm×15 cm. After debridement of necrotic soft tissue, sternum and rib, infected median sternotomy wound was reconstructed with rectus abdominis myocutanous flap, pectoralis major myocutanous flap and latissimus dorsi flap or single muscle flap. The sizes of flaps ranged from 3 cm×5 cm to 5 cm×16 cm.Results Allpatients were followed up from 3 to 11 months with anaverage of 6 months. All the patients achieved healing by first intention with normal respiration and normal function of upper limbs. The wound of donor site healed well.No abdominal hernia and other complications occurred. The wound of donor site healed well.The results were satisfactory.Conclusion According to different stages of the disease and different conditions of an operation, the surgical management should vary with each individual.
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.
目的 探讨急性化脓穿孔性阑尾炎术后切口感染的相关因素。方法 回顾性分析2009年1月至2011年6月期间我院普外科手术治疗的化脓穿孔性阑尾炎161例患者的临床资料。结果 161例患者中35例(21.7%)发生了切口感染。单因素分析结果表明,肥胖(体质指数>30kg/m2)、手术时间超过1h、术前未预防性应用抗生素及术后首次切口换药时间>3d者切口感染发生率高(P<0.05);多因素分析结果表明,手术时间超过1h及术前未预防性应用抗生素是急性化脓穿孔性阑尾炎术后切口感染的独立危险因素(P<0.05)。结论 早期诊治、降低手术时间、术前合理预防性应用抗生素有助于减少切口感染机会。
