Objective To investigate the causes of benign thoracic disease unplanned reoperation,improve the level of diagnosis and treatment and reduce the rate of unplanned reoperation. Methods From May 2006 to May 2016,594 cases of benign thoracic disease were performed thoracic surgery,including 16 patients underwent the unplanned reoperation due to various reasons. The clinical characteristics, therapy course and results of benign thoracic disease unplanned reoperation were analyzed retrospectively. Results The patients underwent the unplanned reoperation were no deaths. The operative time 30～215(135.6±47.4)min, intraoperative blood loss 50～650 (313.6±93.1)mL,postoperation hospitalization duration 7～30(15.7±6.8)d. The causes of benign thoracic disease unplanned reoperation were as follows: postoperative bleeding (10 cases), prolonged air leaks (4 cases),incision infection (2 cases). Univariate analysis showed first-time classification of diseases, operative time and operation method were statistically significant (P<0.05), Multivariate Logistic regression analysis revealed first-time classification of diseases, operative time and operation method were independent factors associated with benign thoracic disease unplanned reoperation. Conclusion According to the different classification of benign thoracic disease to estimate and prevent possible complications, we need to have sufficient preoperative preparation, intraoperative careful operation. Early active processing can be taken in postoperative complications.It can reduce the incidence of unplanned reoperation in benign thoracic disease,especially the chest inflammatory diseases.

目的 比较腹腔镜前列腺癌根治术(laparoscopic radical prostatectomy,LRP)后发生尿失禁(postprostatectomy incontinence,PPI)与没有发生PPI的患者在尿动力学上的差异,为临床诊疗提供尿动力学依据。方法 对87例LRP术后的患者按术后是否并发PPI分成两组,行尿动力学检查后进行比较分析。结果 PPI组患者术中保留一侧或双侧神经血管束的比例少于非PPI组,且最大尿道闭合压(maximum urethral closure pressure,MUCP)、最大膀胱容量(maximum cystometric capacity,MCC)、排尿时膀胱开口压力和最大逼尿肌压均较非PPI组低。而腹压漏尿点压试验阳性与临床上是否漏尿并不完全相符。多变量回归分析表明,术中保留神经血管束、MUCP和MCC是PPI的相关因素。结论 PPI与LRP术中保留神经血管束、MUCP和MCC独立相关。尿动力学检查能为更精准有效指导临床治疗提供依据。

Objective To compare the urodynamic parameters in men with and without postprostatectomy incontinence(PPI) after laparoscopic radical prostatectomy(LRP). Methods 87 patients of prostatic carcinoma after LRP were divided into two groups according to have PPI or not. After urodynamic study, the data were collected to find the difference. Results Overall, the proportion of preservation of unilateral or bilateral neurovascular bundles(NVBs) during LRP was lower in PPI group than that in non-PPI group. Besides, the patients in PPI group had lower maximum urethral closure pressure (P=0.04), maximum cystometric capacity (P=0.04), detrusor pressure during opening (P=0.02)and maximum detrusor pressure (P<0.001), as compared with those in non-PPI group. In the multivariate logistic regression, the preservation of unilateral or bilateral NVBs, MUCP and MCC were identified as the related factor with PPI. Conclusion PPI is significantly associated with the preservation of unilateral or bilateral NVBs, MUCP and MCC. Urodynamic test can be used to make the treatment for PPI. It will be more accurate and effective in clinical practice.
