Objective To investigate the measures to prevent the anastomotic leakage following anterior resection of rectum. Methods A series of seventy-four patients with rectal cancer undergoing anterior resection from January 1991 to October 1998 were analyzed.Results The clinical anastomotic leakage rate was 4.05 per cent (3/74). The causes of leakage were presacral infection and insufficiency of blood supply in incisional margin. Conclusion The proximal colon must be completely mobilized and blood supply of incisional margin should be sufficient. Persistent postoperative presacral suction must be performed to protect fluid accumulation resulting in infection. Intracolonic drainage is an important factor in prevention of anastomotic leakage. Temporary stoma is not necessary.
For a long time, the monitoring of ventilator-associated pneumonia (VAP) has many drawbacks, such as complex diagnostic criteria, high subjectivity, low comparability, low attributable mortality, and difficulty in automated monitoring. The U.S. Center for Disease Control and Prevention proposed a new monitoring definition of ventilator-associated event (VAE) in January 2013 to address the existing problems of VAP. VAE monitoring can better predict the adverse prognosis of patients, adopt objective diagnostic criteria, and realize automatic monitoring. However, VAE surveillance also has some shortcomings: poor identification of VAP patients, lack of sufficient evidence of preventive strategies so far, inconclusive application in neonates and children groups, as easy to be interfered with as VAP. The applicability of VAE in China, its risk factors and preventive strategies need to be further studied.
目的 探讨直肠癌前切除术吻合口漏的原因及对策。方法 对符合行直肠前切除术的73例直肠癌患者行全直肠系膜切除术,用双吻合器技术（double-stapling technique,DST）吻合结直肠。2004年1月以后收治的病例特别注意了会阴助推、 远侧直肠密闭试验、吻合器穿刺头穿刺点的选择、吻合口漏气试验和经肛门至结肠及经腹壁至吻合口旁放置引流管的技术细节。结果 全组2例(2.74%)发生吻合口漏，均为2004年1月以前的病例，1例经横结肠造瘘治愈，另1例经引流管冲洗治疗治愈； 2004年1月以后的65例无吻合口漏发生。结论 注意直肠癌前切除术中的一些技术细节， 可在一定程度上降低全直肠系膜切除条件下DST吻合的吻合口漏发生率。
ObjectiveThis study aimed to discuss the risk factors associated with the delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.MethodsClinical data were collected retrospectively on 130 consecutive patients undergoing defunctioning ileostomy following sphincter-preserving surgery for rectal cancer, between January 2014 and December 2014 in the Sixth Affiliated Hospital of Sun Yat-sen University. According to the reversal time of ileostomy, the patients were divided into two groups, including the delay reversal ileostomy group (≥120 d, n=72) and the normal ileostomy group (<120 d, n=58).ResultsOne hundred and thirty patients were studied (median time to reversal 132 d, range 39–692 d). Logistic regression model showed that adjuvant chemotherapy (OR=14.106, P=0.002), distance of tumor from the anal verge (OR=0.019, P=0.002), and anastomotic leakage (OR=32.440, P=0.001) were significant independent risk factors for delayed reversal. Time to reversal was significantly longer in those patients who had adjuvant chemotherapy, anastomotic leakage, and short distance of tumor from the anal verge.ConclusionAdjuvant chemotherapy, short distance of tumor from the anal verge, and anastomotic leakage are the independent risk factors for delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.
【摘要】目的评估双吻合器在直肠癌保肛术中的应用价值，并探讨吻合口漏等并发症的防治措施。方法对81例采用双吻合器行直肠癌前切除术患者的临床资料进行回顾性分析。结果全组术中肿瘤切除后远端直肠的缝合、吻合过程顺利，手术时间120～190 min,平均160 min。术后发生吻合口漏3例（3.7%），吻合口狭窄1例（1.2%），无手术死亡。结论双吻合器技术可帮助外科医生顺利完成直肠癌前切除术中结直肠的吻合，并且安全、可靠。
Objective To investigate the changes in terms of knowledge, attitudes, behavior, and mental status in hospital outpatients after the Wenchuan earthquake so as to provide more convenient and efficient outpatient services for patients from the disaster areas. Method A self- designed questionnaire was used to survey the outpatients in West China Hospital. Data analysis was performed with SPSS 13.0 software. Result The duration of earthquake feeling was correlated with age, gender, family address, disaster experience, and casualties of relatives and friends. Sleep quality after the earthquake was also significantly correlated with age, gender, family address, disaster experience, casualties of relatives and friends, and the duration of eartqhauke feeling. Seeking medical treatment after the earthquake was associated with the availability of medical insurance. Knowledge about post-quake epidemics was correlated with the responders’ educational background. Conclusion Stress response is related to age and disaster experience. Many factors may effect the development, extent, and duration of people’s stress response. People became more aware of risk after the quake and had a b demand for post-disaster psychological counseling.
早产儿视网膜病变（ROP）是儿童盲的重要致盲原因之一，随着ROP防治指南的颁布以及ROP筛查工作的开展，我国ROP发病率和致盲率有所下降。正确认识和理解ROP分类、筛查标准和治疗指南；建立完善的ROP筛查体系，提高筛查水平；加强ROP临床和基础研究，将有助于进一步降低我国ROP发病率和致盲率
The authors invrstigated whenther samll dose of ursodeoxycholic acif treatment influences biliary concentration, nucleation time and gallbladder empting. 3 patients with cholesferd gallstones receired 400 mg ursodeoxychilic acid per prior to cholecystectomy. Treatment with small dose of ursodeoxycholic acid decreased the gallbladder chlesterol saturation index and prolonged the nucleation time ,bur had no effect on gallbladder empyting. We bilieve that snall dose of ursodeoxyxholic acis mat prevent the gallstone formation by decreasing xholecterol saturation index and lengthening the nucleation time.
