目的 总结术后早期炎性肠梗阻的临床特点及诊治经验。方法 回顾性分析我院2004年1月至2010年12月期间收治的22例腹部手术后早期炎性肠梗阻患者的临床资料。结果 全组均行保守治疗，均治愈出院。肠梗阻解除时间平均6.5d。2例出院后再次出现慢性肠梗阻，经保守治疗好转。结论 术后早期炎性肠梗阻在腹腔严重感染性疾病术后多见，治疗以保守治疗为主，同时应动态观察腹部症状、体征变化，严防误诊、误治。
目的 探索急性化脓性梗阻性胆管炎20世纪90年代后期与80年代以前的差异，探讨对本病治疗的方向。 方法 收集我院1996～2000年病例，并与我院1950～1981年资料进行比较。 结果 ①发病率显著降低，从46.08%降至15.62%； ②发病年龄延后10～20岁； ③入院时病情相对较轻，有休克者从51.39%降至22.80%； ④病死率明显下降，从25.78%降至3.50%； ⑤再手术患者显著增加，从12.12%增至55.20%。造成上述差异的原因与患者就诊早，及时的治疗，医务人员的水平提高，药品与医学的发展等有关。 结论 对急性梗阻性化脓性胆管炎患者，虽然发病率和死亡率已明显下降，仍需足够重视，因术后T管造影和B超检查发现肝内残石或胆管狭窄者，高达85.1%，复发再手术率达55.2%，远不能令人满意。为提高远期效果，应在急诊手术引流后，待患者病情平稳后，再进一步检查和彻底处理肝内病变。
摘要:目的:探讨老年人梗阻性大肠癌的围手术期处理。方法:回顾性分析2003年至2008年间71例60岁以上老年人梗阻性大肠癌的围手术期处理情况。 结果:术前发现并存病者43例,术中出现并发症19例,术后发生并发症37例得,除5例死亡外,均得到有效控制,死亡原因与并存疾病有关。结论:加强围手术期处理,积极治疗并存疾病,老年人梗阻性大肠癌的治疗同样能取得满意的效果。Abstract: Objective:To study the perioperative measures for the aged patients with Obstructive Colorectal Cancer. Methods: Seventyone cases above 60 years with Obstructive Colorectal Cancer were analysed retrospectively on their individual accompanied diseases and perioperative treatments, from 2003 to 2008.Results: Fortythree cases of them had suffered from other diseases. Midoperative complications occurred in 19 cases. Postoperative complications occurred in 37 cases. Except 5 cases of death, complications occurring in others cases were well controlled. The death causes mainly were correlated with accompanied chronic diseases. Conclusion: Strengthen care, active management of other chronic diseases are important significantly for senile patients with colorectal carcinoma to get satisfied outcome.
【Abstract】Objective To explore the relation between the expression of telomerase and DNA ploidy with biliarypancreatic system cancer, so as to find a better way to diagnose and distinguish jaundice between malignance and benign disease.Methods Endoscopic retrograde cholangiopancreatography (ERCP) were performed before operation in patients with obstructive jaundice. The bile and pancreatice juice were collected before ERCP. Biopsy specimens from part of patients were obtained during ERCP. All cancer specimens were possessed once again during operation and were assessed by the activity of telomerase and DNA ploidy. Results ① Telomerase positive rate 〔87.50%(56/64)〕 of tissue specimens in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕，P=0.000. ② Telomerase positive rate〔71.88%(46/64)〕of Bile and pancreatice juice in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕， P=0.000, tissue specimens obtained by endoscopy with malignant obstructive jaundice had detectable telomerase activity, positive rate was 83.33%（20/24）. ③ The rate of DNA heteroploid with malignant obstructive jaundice was 62.50%（40/64）, that of diploid can be seen in all patients with benign obstructive jaundice, the difference was statistically significant (P=0.000). ④ The rate of telomerase positive and DNA heteroploid in high differentiation tumor were significantly lower than in middlelow differentiation tumor （P=0.028，P=0.001）.Conclusion Applying the duodenoscope we collected the bile and pancreatic fluid before operation and obtain biopsy specimens whose telomerase activity and DNA ploid were detected. This is simple, safe, quick method which can identify the malignant and benign obstructive jaundice.
目的 观察左侧结肠癌伴急性肠梗阻一期手术的疗效，探讨理想的手术治疗方法。方法 回顾性分析四川大学华西医院2007年1月至2009年11月期间收治的46例左侧结肠癌伴急性肠梗阻患者一期手术切除吻合的临床资料。结果 46例均未实施术中结肠灌洗，而行彻底的无污染肠减压法。其中行根治性切除一期吻合35例，姑息性切除一期吻合11例。术后发生吻合口漏3例，切口感染6例，肺部感染2例，盆腔积液1例，均经非手术方法治愈。全组手术无死亡病例。结论 左侧结肠癌伴急性肠梗阻一期切除吻合，用彻底的无污染肠减压法替代结肠灌洗是安全、可行的。
目的 探讨腹腔镜粘连松解术治疗粘连性肠梗阻的应用价值。方法 对我院2005年7月至2011年9月期间采用腹腔镜进行肠粘连松解术的27例患者的临床资料进行回顾性分析。结果 27例患者中除2例因术中探查发现小肠坏死而中转开腹行肠切除外，其余25例均手术成功，手术时间（65±15） min （40～115min）。27例均获随访，随访时间（14±6）个月（8个月～2年），1例患者于术后1个月时有阵发性腹痛，经保守治疗缓解，其余病例均无腹胀、腹痛等症状发生。结论 腹腔镜粘连松解术治疗粘连性肠梗阻具有创伤小、恢复快的优点，是较理想的治疗术后肠粘连的手段。
目的 探讨预防左半结肠癌伴梗阻Ⅰ期切除吻合术后吻合口漏发生的新方法。方法 将215例左半结肠癌伴梗阻接受术中结肠灌洗和Ⅰ期切除吻合等处理的患者分为两组。双管引流组术中经肛门放置肠腔内双管引流；扩肛组术中不放置肠腔内引流管，术后定时扩肛。对两组患者术后腹腔脓肿和吻合口漏发生率进行对比分析。结果 腹腔脓肿和吻合口漏发生率双管引流组分别为3.1%(4/130)和3.8%(5/130)，扩肛组分别为10.6%(9/85)和12.9%(11/85)，两组腹腔脓肿和吻合口漏发生率之差异均有显著性意义(P＜0.05)。结论 肠腔内双管引流法具有预防性结肠“内造瘘”、减压减张、冲洗洁净和持续性扩肛作用，能有效地预防和减少左半结肠癌伴梗阻I期切除吻合术后吻合口漏的发生。
Objective To investigate the effects and mechanisms of bile on small intestine mucosal barrier.Methods Fifty Wistar rats were assinged into 3 groups randomly: obstructive jaundice (OJ) group （n=20）, biliary external drainage group （n=20） and control group （n=10）. Ten days after operation, the plasma endotoxin level was determinated, the terminal ileum mucosas was obtained to be morphologically measured by light microscope, and immunohistochemistry and Western blot were uesd to examine the expressions of tight junction proteins zona occludens-1 (ZO-1) and occludin in the mucosas. Results Atrophy significantly appeared in the distal ileum mucosas in OJ group. Compared with control group, the intestinal villus height, mucosa thickness and crypt depth in OJ group were obviously decreased 27.8%, 21.7%, and 25.4% (P=0.001, 0.001, 0.040). There were no differences between external drainage group and control group (P=0.050, 0.070, 0.080); While the values of external drainage group were significantly higher than those in OJ group (all P=0.001). The level of plasma endotoxin was up to (1.49±0.27) EU/ml in OJ group compared with control group 〔（0.27±0.09） EU/ml〕, P=0.001. In external drainage group, the value was （0.91±0.25） EU/ml, which was obviously higher than that in control group and lower than that in OJ group （all P=0.001）. Immunohistochemical study showed b positive expression of ZO-1 dropped from 7/10 in the control group to 6/20 in OJ group （P=0.040）, occludin expression was 8/10 in control group and 7/20 in OJ Group （P=0.020）; expressions of them in external drainage group 〔8/20 （P=0.100,0.210） and 9/20 （P=0.060, 0.200）〕 displayed no significant differences compared with the other twogroups. Quantitative testing of Western blot showed the expressions of ZO-1 and occludin in OJ group were significantly lower than those in control group (P=0.001, 0.010), the values in external drainage group were higher than those in OJ group （P=0.005, 0.014）. The expression of ZO-1 was lower in external drainage group than that in control group (P=0.001), and there was no significant difference of occludin between the two groups (P=0.062）. Conclusion Lack of intestinal bile will undermine the intestinal tight junction protein composition, and make intestinal mucosal barrier impaired. The intestinal barrier more severely injured when biliary tract obstructs because of multiple factors. Bile plays an important role in the maintenance of intestinal mucosal barrier.
