目的 探讨内镜逆行胰胆管造影(ERCP)检查及内镜治疗在腹腔镜胆囊切除(LC)术前、术后的应用价值。 方法 对61例拟行LC的患者术前或术后行ERCP检查，发现异常再行内镜治疗。结果 LC术前行ERCP者42例中39例显影，其中37例伴有其他胆管疾病，占94.9%。术后行ERCP者19例均显影，总的插管成功率为95.1%。LC术前或术后42例行EST治疗，4例行EPBD，2例行ERBD，15例行ENBD，另4例在行ERCP检查后改开腹手术，取石成功率为92.9%。结论 诊治性ERCP在LC前、后的应用，对进一步明确诊断、选择手术方式、预防LC的并发症和提高LC的成功率具有重要价值。
Objective To investigate therapeutic effect of endoscopic sphincterotomy with small incision (SES) combined with endoscopic papillary balloon dilation (EPBD) in treatment of larger common bile duct stones. Methods The clinical data of 80 patients with common bile duct stones treated in our hospital from February 2014 to October 2015 were retrospectively analyzed. These patients were divided into endoscopic sphincterotomy (EST) group (n = 40) and SES+EPBD group (n = 40) according to the therapeutic methods. The diameter of common bile duct stone was 10–20 mm. The operation status, recurrence rate and residual rate of common bile duct stone, and complications rate within 3 months after operation were compared between these two groups. Results The age and gender had no significant differences between these two groups (P>0.05). The operation time was shorter (P<0.05) and the intraoperative bleeding was less (P<0.05) in the SES+EPBD group as compared with the EST group. There were no significant differences in the hospital stay and recovery time of gastrointestinal function between these two groups (P>0.05). The levels of ALT, AST, DBIL, and TBIL in these two groups before treatment had no significant differences (P>0.05); after treatment, the above indicators of liver function in the SES+EPBD group were significantly lower than those in the EST group (P<0.05), and which were significantly decreased more in the same group (P<0.05). The residual stone, stone recurrence, and complications such as acute pancreatitis, acute cholangitis, bile leakage and postoperative hemorrhage were not found in the SES+EPBD group, the rates of these indicators in the SES+EPBD group were significantly lower than those in the EST group (P<0.05). Conclusion SES combined with EPBD has a good therapeutic effect on larger common bile duct stones (diameter of common bile duct stone is 10–20 mm) and recurrence rate is low.
目的 探讨CT仿真内镜（CT virtual endoscopy，CTVE）在低位直肠癌术前分期中的价值。方法 收集我院2008年8月1日至2011年3月1日期间的直肠癌患者57例，术前行直肠CTVE检查，详细记录患者直肠癌周围组织浸润和淋巴结转移的情况；患者术后常规进行病理检查，比较两者结果的差异。结果 术前直肠CTVE检查与术后石蜡病理检查对直肠癌周围淋巴结转移的判断经四格表χ2检验，差异无统计学意义（χ2=2.5，P＞0.05），其对直肠癌周围淋巴结转移预测的敏感性为66.67%，特异性为93.94%。术前直肠CTVE预测直肠癌周围组织浸润和术后病理检查结果经四格表χ2检验，差异有统计学意义（χ2=4.4，P＜0.05），其对直肠癌周围组织浸润判断的敏感性为27.78%，特异性为42.86%。结论 CTVE在术前评估直肠癌周围淋巴结转移有较高的可信性，但对直肠癌周围组织浸润的评价较差。
Endoscopic retrograde cholangiopancreatography is one of the main methods for the diagnosis and treatment of biliary tract and pancreatic diseases. Compared with other digestive endoscopes, duodenoscopy has a special structure. Since the outbreaks of nosocomial infections caused by the transmission of multidrug-resistant organism through duodenoscopy in 2010, the reprocessing and design of digestive endoscopes represented by duodenoscopy have faced new challenges. This article reviews the international advances in duodenoscopy reprocessing in the past 10 years including the structural characteristics of duodenoscope, related infection outbreak cases, outbreak control measures, and the use of disposable duodenoscopy, so as to provide guidance and reference for the duodenoscopy reprocessing and related nosocomial infections prevention and control work in China.
ObjectiveTo summarize the current common clinical laparoscopic gastrointestinal tumor surgical localization methods, and to provide reference for clinicians to choose reasonable localization methods. MethodThe domestic and foreign literatures related to laparoscopic gastrointestinal tumor surgical localization methods were searched and reviewed. ResultsThe common localization methods for laparoscopic gastrointestinal tumor surgery were imaging localization, preoperative endoscopic localization, intraoperative endoscopic localization and intraoperative fluorescence localization, among which abdominal enhanced CT and endoscopic-related localization methods were the most commonly used localization methods in clinical practice at present. ConclusionA variety of methods are available for surgeons to choose from, and the precise localization of tumors is better facilitated by combining multiple methods.
【摘要】目的探索内镜直视下应用带膜记忆合金支架对晚期食管、贲门恶性狭窄的介入治疗方法。方法2005年1月2009年11月对49例失去手术机会或拒绝手术的晚期食管癌或贲门癌致食管或贲门狭窄患者,行电子胃镜引导下放置镍钛合金支架;对狭窄程度重、胃镜不能通过者,先行Savary探条扩张再放置支架。结果49例均成功置入支架,解除狭窄有效率达100%。结论内镜直视下带膜支架置入操作方法简便、安全,可改善患者的生存质量,延长生存时间。
