摘要:目的：回顾性分析比较左半结肠癌急性梗阻一期手术与同期左半结肠癌根治术患者的手术临床资料,探讨左半结肠癌急性梗阻一期手术的可行性。方法： 回顾性将我中心2004年1月至2007年3月收治的59例左半结肠癌急性梗阻一期手术病例分为A组,将同期226例左半结肠癌根治术病例分为B组,比较两组之间清除淋巴结数、术后进食时间、吻合口漏发生率、肺部感染率、切口感染率、住院时间、复发和转移率。结果： 在上述观察指标中,在A组分别为（133±18）枚,（36±09）d,1/59（169%）,4/59（678%）,2/59（339%）,(124±09)d,6/59（1017%）；B组分别为128±15,32±08,1/226（044%）,8/226（354%）,6/226（265%）,117±15,23/226（1062%）；经统计学处理,两组间没有显著性差异。结论：术中合理应用结肠灌洗,良好的手术技巧,术后积极辅助治疗,左半结肠癌急性梗阻一期手术是安全可行的,可避免二次手术带给患者的痛苦,术后并发症也无明显增加。Abstract: Objective: Retrospective analysis and comparison of acute obstruction of left colon cancer onestage surgery and the same period a radical mastectomy in patients with left colon cancer surgery clinical data,To study the possibility of acute obstruction of left colon cancer onestage surgery. Methods:A retrospective of my center from January 2004 to March 2007 were treated 59 cases of acute obstruction of left colon cancer onestage surgery patients were divided into A group, will be left over the same period 226 cases of radical resection of colon cancer patients were divided into group B, compare the number of lymph nodes removed between the two groups, after the consumption of time, the incidence of anastomotic leakage, pulmonary infection, incision infection, length of stay, recurrence and metastasis rate. Results: Observed in the above indicators, in the A group were 133±18,36±09,1/59 (169%),4/59 (678%), 2/59 (339%),124±09,6/59 (1017%); B group were 128±15,32±08,1/226 (044%), 8/226 (354%), 6/226 (265%), 117±15,23/226 (1062%); Statistical analysis between the two groups there was no significant difference. Conclusion: Rational application of intraoperative colonic irrigation, good surgical technique, postoperative adjuvant treatment of active, acute obstruction of left colon cancer onestage surgery is a safe and feasible, it may avoid the second operation to bring the patient’s pain, postoperative complications and no increased significantly.

Experience of the Treatment of Acute Obstructive Suppurative Cholangitis

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。

Application of The Double Cavity Casing Negative Pressure Drainage by Inside and Outside of The Intestine in The Primary Resection and Anastomosis of Left Colon Cancer Combined with Acute Obstruction

ObjectiveTo investigate the feasibility and safety of the double cavity casing negative pressure drainage by inside and outside of the intestine in the primary resection and anastomosis of left colon cancer combined with acute obstruction. MethodsEighty-one cases of left colon cancer combined with acute obstruction who underwent surgeries in our hospital from January 2009 to December 2012 were collected prospectively, and were divided into one-stage surgery group (n=41) and control group (n=40). Cases of one-stage surgery group received double cavity casing negative pressure drainage by inside and outside of the intestine in the primary resection and anastomosis, and cases of control group underwent two-stage surgeries. Comparison of operation time, blood loss, time of anal exhaust after operation, hospital stay, hospital expense, and incidence of complication between the 2 groups was performed. ResultsThere were no significant difference in the operation time[(166±19) minutes vs. (173±23) minutes], blood loss[(253±42) mL vs. (273±50) mL], and time of anal exhaust after operation[(3.24±0.73) days vs. (3.50±0.95) days]beeween one-stage surgery group and control group, but hospital stay[(15.1±2.3) days vs. (23.1±4.1) days]and hospital expense[(3.70±0.68) ×105 yuan vs. (5.77±0.95) ×105 yuan]of one-stage surgery group were lower than those of control group (P<0.05). In addition, there were no significant difference in the incidences of wound infection[7.3% (3/41) vs. 10.0% (4/40)], intraabdominal infection[4.9% (2/41) vs. 10.0% (4/10)], pulmonary infection[12.2% (5/41) vs. 15.0% (6/40)], and anastomotic leakage[2.4% (1/41) vs. 5.0% (2/40)]beeween one-stage surgery group and control group (P>0.05). All of the cases were followed up for 1-36 months, and the median time were 22 months. There were no significant difference in the mortality[0 (0/41) vs. 2.5% (1/40)], recurrence rate[2.4% (1/41) vs. 5.0% (2/40)], and metastasis rate[7.3% (3/41) vs. 10.0% (4/40)]beeween one-stage surgery group and control group too (P>0.05). ConclusionIn the case of negative pressure drainage of double cavity casing, underwent decompression of the small bowel, and irrigation of colon, the primary resection and anastomosis of left colon cancer combined with acute obstruction was safe and feasible.

Roles of PI3K/AKT-S1PR2 pathway in systemic inflammatory response induced by acute obstructive cholangitis in rats

ObjectiveTo investigate activation of phosphatidylinositol 3 hydroxykinase (PI3K)/AKT pathway and sphingosine 1-phosphate receptor 2 (S1PR2) in peripheral blood mononuclear cells (PBMCs) of acute obstructive cholangitis (AOC) rats and their effects on systemic inflammation in rats.Methods① In vitro experiment: The isolated PBMCs from the rats were divided into 4 groups: a control group, LY294002 treatment group, lipopolysaccharide (LPS) treatment group, and LPS+LY294002 treatment group. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the supernatant were detected and the phosphorylation levels of PI3K and AKT and protein level of S1PR2 in the PBMCs were detected. ② In vivo experiment: The rats were randomly divided into four groups: a control group, LY294002 treatment group, AOC model group, and AOC+LY294002 treatment group. The survival rate of rats was recorded, the liver function (ALT, AST, and TBIL), TNF-α, and IL-6 levels in the serum were detected. The phosphorylation levels of PI3K and AKT and protein level of S1PR2 in the PBMCs of the rats were detected. Results① The results of in vitro experiment: The levels of TNF-α and IL-6 in the LPS+LY294002 treatment group were significantly lower than those in the LPS treatment group (P<0.050). The phosphorylation levels of PI3K and AKT and protein level of S1PR2 in the LPS+LY294002 treatment group were significantly lower than those in the LPS treatment group (P<0.050). ② The results of in vivo experiment: The survival rate of rats in the AOC+LY294002 treatment group was higher than those in the AOC group. The serum levels of ALT, AST, TBIL, TNF-α, and IL-6 in the AOC+LY294002 treatment group were significantly lower than those in the AOC model group (P<0.050). The phosphorylation levels of PI3K and AKT and protein level of S1PR2 in the AOC+LY294002 treatment group were significantly lower than those in the AOC model group (P<0.050).ConclusionInhibition of activation of PI3K/AKT pathway in PBMCs can inhibit expression of S1PR2, then alleviate systemic inflammatory response induced by AOC in rats.
