【Abstract】Objective To introduce the current studies of the role of vascular endothelial growth factorC (VEGFC) and VEGFD in lymphangiogenesis and lymph node metastasis of gastrointestinal neoplasma. Methods The related literatures in recent 5 years were reviewed. Results The growth factors VEGFC and VEGFD enhance lymphangiogenic metastasis of gastrointestinal neoplasma with the property of angiogenesis and lymphangiogenesis. In gastric adenocarcinoma, VEGFC mRNA and tissue protein expression correlate with lymphatic invasion, lymph node metastasis, venous invasion and reduced 5year survival rates. The role of VEGFC in esophageal squamous cancer and colorectal cancer and VEGFD in colorectal cancer is not certain, with conflicting reports in the published literatures.Conclusion The VEGFC, VEGFD/VEGFR3 signal pathway may become the ideal target for inhibition of tumor proliferation and metastases, antilymphangiogenesis therapy may be a novel potential strategy in tumor biological therapy.
ObjectiveTo systematically review the efficacy of Chinese herbal enema in ileus patients. MethodsThe randomized controlled trials (RCTs) and quasi-RCTs about Chinese herbal enema and gastrointestinal intubation versus western medicines in the treatment of ileus disease was searched in PubMed, Web of Science, EMbase, The Cochrane Library (Issue 4, 2013), CBM, CNKI, VIP and WanFang Data from the date of their establishment to July 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.1. ResultsA total of 27 RCTs and 3 quasi-RCTs involving 3 074 patients were included. The results of meta-analysis showed that the Chinese herbal enema and gastrointestinal intubation group was superior to the control group in raising the total clinical effective rate (OR=4.69, 95%CI 3.70 to 5.94, P < 0.000 01), as well as shortening the hospitalization time (SMD=-1.19, 95%CI-1.42 to-0.96, P < 0.000 01), time of anus exhaust (SMD=-1.52, 95%CI-1.76 to-1.28, P < 0.000 01), defecation (SMD=-2.27, 95%CI-3.43 to-1.11, P=0.000 1), time of gastric tube indwelling (SMD=-1.56, 95%CI-1.86 to-1.27, P < 0.000 01), and symptoms complete resolution (SMD=-0.74, 95%CI-1.11 to-0.37, P < 0.000 1), all with significant differences. ConclusionChinese herbal enema and gastrointestinal intubation is more beneficial than western medicine alone for ileus. Due to limited quality of the included studies, the abovementioned conclusion still needs to be verified by conducting more high quality blinding RCTs.
ObjectiveTo investigate the specific CT findings of high-risk gastrointestinal stromal tumors (GISTs). MethodsCT findings of 24 patients with high-risk GISTs from August 2009 to March 2014 proved by surgery and pathology were retrospectively reviewed. ResultsTwelve of the high-risk GISTs were from the stomach, 11 from the small intestine (5 from duodenum, 4 from jejunum, and 2 from ileum), and 1 from the rectum. The biggest transverse diameter of the tumor was between 2.5 and 15.0 cm, and 2 were less than 5 cm and 22 of them were over 5 cm. The tumors appeared as irregular in 20 cases, and with indefinite boundary in 21 cases. Twenty-four tumors showed different levels of necrosis and cystic change, 15 showed ulcer, 2 showed perforation with effusion and pneumatosis, and 3 showed calcification. The enhancement of lesion was mostly moderately to markedly inhomogeneous. High-risk small intestinal stromal tumors had more significant enhancement and vessels. Hepatic metastasis in 3 cases was detected. ConclusionCT features of HRGISTs can be found with certain characteristics, which may contribute to the diagnosis.
ObjectiveTo investigate the reason, prevention, and treatment measures of gastrointestinal unplanned reoperation. MethodsClinical data of 21 patients who carried out gastrointestinal unplanned reoperation for various reasons from Jun. 2012 to Jun. 2013 in our hospital were retrospectively analyzed. ResultsTwenty-one of 2 492 patients with gastrointestinal tract surgery carried out gastrointestinal unplanned reoperation, and the incidence of reoperation was 0.8%. The causes of reoperation were intra-abdominal hemorrhage in 10 cases, gastrointestinal fistula in 7 cases, inflammatory intestinal obstruction with peritonitis in 1 case, and incision dehiscence in 3 cases. After undergoing suture hemostasis, colostomy, anastomotic fistula repair, debridement, and suture,20 cases were cured or improved, and 1 case died. The median of hospitalization expense was 76 000 yuan(46 000-116 000 yuan), and the median of hospital stay was 25-day(16-49 days). ConclusionsGastrointestinal unplanned reoperation can cause more serious economic and emotional burden to patients, standardizing surgical procedure and enhancing perioperative monitoring can reduce the incidence of unplanned reoperation. In addition, grasp legitimately the indications of reoperation, implement timely, and effective reoperation can avoid further deterioration of the disease.
Objective To investigate preoperative blood neutrophil-to-lymphocyte ratio （NLR） in patients with gastrointestinal stromal tumor （GIST） and analyze the relationship of the NLR to prognosis. Methods The data of NLR of peripheral blood samples on 3d before surgery and the results of immunohistochemistry of 42 patients with GIST were analyzed respectively，the relation between the NLR and the prognosis of patients with GIST was understood by the survival analysis. Results The patients with high NLR （NLR≥2.5） was found in 22 cases， low NLR （NLR＜2.5） in 20 cases.The NLR was related to mitotic figures （χ2=9.45，P=0.002） and tumor size （P=0.041）. The 3-year survival rate of the patients with high NLR was shorter than that of the low NLR （χ2=5.44，P=0.022）. The 3-year survival rate was associated with NLR，mitotic figures，and tumor size （P＜0.05） in univariate analysis. The NLR and mitotic figures were independent prognostic indicators of 3-year survival （P=0.018，P=0.000） in Cox multivariate analysis. Conclusion Blood NLR and mitotic figures have some predictive value for the prognosis of patients with GIST.
Objective To explore how to integrate the various sources of information in designing an evidence-based nursing care plan for preventing gastrointestinal hemorrhage (GIH) after pancreaticoduodenectomy (PD). Method Papers and references about prevention of GIH after PD were searched between September and October 2015, and an evidence-based nursing care plan was drawn up and implemented from November 2015 to January 2016. Results A total of 79 papers were found and of which 17 were aviliable. Thirty-nine patients were cared on the basis of the effective project, of whom one was dignosed with GIH on the 3rd postoperative day and the rate of post-PD hemorrhage was 2.6%. All patients were diacharged on the 6th or 7th postoperative day. Conclusion Exploring evidences under the guidance of scientific method and applying them to clinical nursing can prevent post-PD hemorrhage and improve life quality of patients.
Objective To perform a systematic review on the safety (i.g. cardiovascular, mortality and gastrointestinal bleeding) of clopidogrel versus clopidogrel combined with proton pump inhibitors (PPIs) for the patients with coronary heart disease. Methods Such databases as The Cochrane Library, PubMed, EMbase, SSCI, VIP, CNKI, and CBM were searched from the date of their establishment to September 2010. The bibliographies of the retrieved articles were also checked. The data was extracted and evaluated by two reviewers independently. The RevMan 5.0 software was used for meta-analyses. Results A total of 29 studies were included. The results of meta-analyses showed that the use of clopidogrel combined with PPIs was associated with increasing the risk of cardiovascular events (RR=1.27, 95%CI 1.09 to 1.47), as well as myocardial infarction (RR=1.45, 95% CI 1.20 to 1.76), total mortality (RR=1.23, 95%CI 1.06 to 1.43), and rethrombosis (RR=1.37, 95%CI 1.01 to 1.86). However, there was no enough evidence to reach the conclusion that the combination use could benefit the situation of gastrointestinal bleeding (RR=0.84, 95%CI 0.47 to 1.50). Conclusion?Compared with clopidogrel, the combination use of clopidogrel and PPIs increases cardiovascular events, mortality, and the risks of myocardial infarction and rethrombosis. However, more clinical studies are required to assess the effect of reducing gastrointestinal bleeding.
Objective To evaluate the role of CT in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma. MethodsTwenty preoperative CT scans and clinical data were obtained in 20 patients who subsequently had bowel ruptures verified surgically. CT findings were analyzed retrospectively in these patients. Retrospective interpretation was made by consensus of at least two radiologists. ResultsTwenty cases of CT scan showed intraperitoneal fluid (18 cases), pneumoperitoneum (18 cases), extravasations of gastrointestinal tract contents (2 cases), bowel wall findings (14 cases) and mesenteric injury (15 cases). Conclusion CT is fast, sensitive and noninvasive in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma.
Objective To investigate the effect of short-term administration of growth hormone (GH) on serum insulin-like growth factor-1 (IGF-1) level and nutritional status in patients after gastrointestinal operation, and evaluate whether postoperative application of GH rise the risk of tumor recurrence. Methods Forty-eight patients undergoing major gastrointestinal operation were randomly divided into two groups: GH group （n=24） and control group （n=24）. The two groups received isocaloric isonitrogenous nutrition with daily injection of either GH 0.15 U/kg or placebo for a period of day 3-9 postoperatively. Serum albumin, fibronectin, and IGF-1 were measured before operation as a baseline, and day 3 and 10 after operation using standard laboratory techniques. Nitrogen balance was measured daily from day 3 to day 9 after operation. Postoperative complications and adverse reaction were observed. All cancer patients received regular abdominal B-type ultrasonography and chest X-ray examination during 2 years of follow-up. Results Compared with control group, GH treatment did not influence serum IGF-1 and serum albumin level （Pgt;0.05）, but improved significantly the rise from day 3 to day 10 of serum fibronectin level 〔(22.8±5.8) mg/L vs.（9.6±3.6） mg/L， P＜0.05〕 and the cumulative nitrogen balance 〔（11.37±16.82） g vs.（－9.11±17.52） g， P＜0.01〕 postoperatively. There was no severe adverse effects and complications during GH treatment. The tumor-recurrence rates were not statistically different between two groups during follow-up. Conclusions Short-term administration of low-dose GH combined with early nutrition support can improve total nitrogen retention and protein metabolism, but not influence serum IGF-1 level after major abdominal surgery. Short-term administration of low-dose GH may not cause the tumor-recurrence.
【Abstract】ObjectiveTo study the diagnosis and the treatment of gastrointestinal stromal tumor (GIST). Methods In this retrospective study, tissue slices, including immunohistochemical examinations, of 48 patients with GIST from January 1999 to December 2004 were collected. All of their clinical symptoms, pathologic characters, and surgical treatment and other information were also analyzed. ResultsTwenty-seven males and 21 females with a mean age of 68 were included in this report. All patients received tumor resections. Tumors were located in the stomach in the 29 cases (60.4%), and 11 cases (22.9%) were in the small intestine. The main clinical manifestations were alimentary tract hemorrhage (52.1%) and abdominal mass (35.4%). Immunohistochemical examination showed the positive rate of CD117 was 83.3%(40/48), and CD34 was 77.1%(37/48). Conclusion GIST mostly occurs at stomach and small intestine in aged people with clinical manifestations of alimentary tract hemorrhage and abdominal mass. The diameter of the mass is an important clinical index to distinguish malignant and benign tumors. The diagnosis of GIST depends on the combination of pathological and immunohistochemistry examinations. Complete regional resection of the tumor may be the most effective treatment.
