Objective To evaluate the therapeutic efficacy of percutaneous transhepatic portal vein catheterization and thrombolysis on acute superior mesenteric vein thrombosis. Methods The treatment and therapeutic efficacy of 7 cases of acute superior mesenteric vein thrombosis underwent percutaneous transhepatic portal vein catheterization and thrombolysis under ultrasound guidance from August 2005 to April 2009 were analyzed. Results All the patients succeeded in portal vein catheterization and no bile leakage or abdominal bleeding occurred during the procedure. The clinical symptoms such as abdominal pain, abdominal distension， and passing bloody stool relieved were relieved and liquid diet began at postoperative of day 2-5. Emergency operation was done in one case and there was no intestinal fistula. The angiography after the operation showed that the majority of thrombosis were cleared and the blood of portal vein and superior mesenteric vein flowed smoothly. During the follow-up of 3 months to 3 years, all the patients’ status maintained well and no recurrence occurred. Conclusion Treatment of acute superior mesenteric vein thrombosis by percutaneous transhepatic portal vein thrombolysis is safe and effective.
Objective To prospectively evaluate the health-related quality of life (HRQOL) outcomes in patients undergoing laparoscopic total mesorectal excision (LTME) with anal sphincter preservation (ASP) for low rectal cancers. Methods From June 2001 to March 2004, 125 patients undergoing LTME and 103 patients undergoing OTME were included in this study. The international standard questionnaires (QLQ-C30 and QLQ-CR38) were used to evaluate the conditions of patients at 3 periods after surgery respetively: 3-6 months, 12-18 months, gt;24 months. Results In contrast to OTME patients, the LTME ones showed significantly better physical function during 3-6 months after surgery, less micturition problems within 12-18 months, less male sexual problems and better sexual function during 12-18 months after surgery, with better sexual enjoyment after postoperative 24 months. Both groups showed significant improvement in most subscales from the first to the second assessment, and improvement in sexual enjoyment from the second to the third assessment. The sexual function, micturition problems and male sexual problems in LTME group significantly improved from the first to the second assessment, whereas the sexual function in OTME group improved from the second to the third assessment.Conclusion Patients undergoing LTME for low rectal cancers have bette postoperative HRQOL than patients undergoing OTME, with better physical function, micturition function, overall sexual and male sexual functions in short term, and better sexual enjoyment in the long term. The HRQOL of both LTME and OTME patients may be expected to improve over time, particularly in the first postoperative year.
ObjectiveTo explore the protective effect of low-molecular-weight heparin calcium (LHC) combined with trimetazidine on intestinal smooth muscle of intestinal acute mesangial vein thrombosis (AMVT) in rats and it's mechanism of effect. MethodsA total of 120 SD male rats were randomly divided into three groups, with 40 rats in each group. LHC group: after the AMVT model established, rats were subcutaneous injection the LHC (30 U/100 g) per 12 h until 72 h after surgery. LHC+trimetazidine group (LHCT group): after the AMVT model established, rats were subcutaneous injection the LHC (30 U/100 g) and tail vein injection the trimetazidine (10 mg/kg) per 12 h until 72 h after surgery. Normal saline group (NS group): after the AMVT model established, rats were subcutaneous injection the NS (0.2 mL/100 g) per 12 h until 72 after surgery. The AMVT model were established by blocking superior mesenteric vein of 8 cm and the edge vein arch. Vena cava blood samples and intestinal segments were collected sequentially at 6 h, 12 h, 24 h, 48 h and 72 h afrer surgery. The levels of malondialdehyde (MDA) and creatine kinase (CK) in the blood, and the level of ATP in the intestinal tissue samples were measured with ELISA. Intestinal tissue were taken from the rats for inestinal tissue section, stained with hematoxylin and eosin, examined under light microscopy and evaluated histopathologically using mesemeche scoring system at different time. ResultsCompared with the LHC group and NS group, the levels of MDA and CK in blood and histopathology score of intestinal tissues in rats were significantly decreased, and the level of ATP significantly increased in LHCT group at different time point (P < 0.05). ConclusionTrimetazidine can improve intestinal smooth muscle energy metabolism in the AMVT disease, comined with LHC early can avoid intestinal smooth muscle wall permeability coagulation necrosis and reduce the intestinal smooth muscle damage.
目的 探讨腹腔镜全直肠系膜切除术盆腔自主神经保留的可行性及对术后性功能的影响。方法 对我院2004年2月至2006年5月期间21例中低位直肠癌患者施行腹腔镜全直肠系膜切除保留盆腔自主神经手术，调查了解患者术后性功能情况。结果 21例患者性功能均存在,绝大多数(18例)患者勃起功能良好。结论 腹腔镜下全直肠系膜切除术保留盆腔自主神经是可行的，患者性功能恢复满意。
ObjectiveTo analyze the therapeutic effects of open surgery and endovascular treatment for mesenteric venous thrombosis.MethodsThe clinical data of 22 patients with mesenteric venous thrombosis from March 2005 to January 2014 were analyzed retrospectively. One patient underwent open surgery including removal of necrotic small intestine and thrombectomy of superior mesenteric vein immediately admission to the hospital. Five cases were treated with simple anticoagulation and cured. Sixteen cases received thrombolytic therapy after primary anticoagulant therapy.ResultsOne case who underwent open surgery died of multiple organ failure at 72 h after the surgery. Five cases who received simple anticoagulant reached clinical relief finally. Sixteen patients who received thrombolytic therapy achieved recanalization totally or partially. Three cases died during follow-up (3 months to 7 years, average) of which 1 died of recurrence of acute superior mesenteric venous thrombosis, 1 died of myocardial infarction, and 1 died of stroke.ConclusionsFor patients with symptomatic mesenteric venous thrombosis, if there is no intestinal necrosis, there will be encouraging results by interventional thrombolytic therapy. And the treatment effect needs further experience accumulation in more cases.
目的 探讨小儿结肠系膜淋巴管瘤的诊断与治疗方法。方法 回顾性分析我院2006年1月至2011年12月期间手术治疗的5例小儿结肠系膜淋巴管瘤的临床资料。结果 3例诊断为腹腔包块性质待查的患儿，术中发现腹腔肿块来源于乙状结肠系膜，其中1例肿块侵犯到降结肠系膜达结肠脾曲而行左半结肠切除＋肠吻合术，另外2例行乙状结肠系膜淋巴管瘤切除＋部分乙状结肠切除＋肠吻合术；1例患儿诊断为急性化脓性阑尾炎合并乙状结肠系膜淋巴管瘤，行阑尾切除＋乙状结肠系膜淋巴管瘤切除＋肠吻合术，1例患儿诊断为乙状结肠系膜淋巴管瘤破裂并弥漫性腹膜炎，行乙状结肠系膜淋巴管瘤切除＋乙状结肠造瘘术，术后6个月后再行二期手术。5例患儿手术后恢复良好，未发生吻合口漏等并发症。术后随访5个月～5年， （2.3±1.1）年，1例失访，余均存活，仍在随访中，所有病例均未复发。结论 日常行阑尾手术中，应常规探查小肠、结肠；未进行肠道准备的结肠一期吻合手术中结肠灌洗可减少吻合口漏等并发症的发生率；腹腔感染严重的患儿结肠一期吻合不可取，结肠造瘘安全；小儿结肠系膜淋巴管瘤术前确诊困难，反复出现腹痛、腹部包块的患儿应想到结肠系膜淋巴管瘤的可能性，行充分的肠道准备后择期手术，手术是肠系膜淋巴管瘤唯一的治疗方法。
