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.
ObjectiveTo summarize the research progress of CT related to esophageal varices of cirrhotic patients complicated with portal hypertension.MethodsRelevant CT literatures of esophageal varices of cirrhotic patients complicated with portal hypertension were collected to make an review,then summarized the research status and progress of CT in the diagnosis and evaluation of lower esophageal varices.ResultCT had a good correlation with endoscopic diagnosis of esophageal varices, and CT was of great value in evaluating the presence, degree, and risk of esophageal varicose veins, especially in predicting the risk of esophageal varicose veins, which could be used as an effective modality to assist endoscopic examination to a certain extent.ConclusionsCT is an important examination method for esophageal varices, which has important value in diagnosis and evaluation. In the future, more further researches can be carried out to provide more strong and accurate support for the diagnosis and treatment of esophageal varices.
ObjectiveTo investigate the relationship between chronic obstructive pulmonary disease (COPD) and respiratory failure in patients with upper gastrointestinal bleeding and recent prognosis. MethodsWe retrospectively analyzed the clinical data of 73 patients with COPD and respiratory failure treated from February 2009 to May 2011. The patients were assigned to the observing group (n=33) and control group (n=40). General characteristics, improvement rates, mortality rates, lengths of hospital stay, endotracheal tube rates and arrhythmia rates were compared between the two groups. ResultsAge, sex, and medical history of the patients were similar in both groups (P>0.05). Compared with the control group, the improvement rate was lower (P<0.001), the mortality rate (P<0.001), length of hospital stay (P<0.001), endotracheal tube rate (P<0.05) and arrhythmia rate (P<0.05) were all higher in the observing group after treatment. ConclusionUpper gastrointestinal bleeding is a high risk factor for short-term prognosis patients with COPD and respiratory failure.
Objective To assess the clinical efficacy and safety of proton pump inhibitor （PPI） and H2RA for stress ulcer bleeding in stroke patients. Methods Randomized controlled trials （RCT） were identified from MEDLINE （ 1966- Oct. 2005 ） ,EMBASE （ 1984- Oct. 2005 ）, The Cochrane Library （ Issue 4,2005 ）, CBMdisc （ 1980- Oct. 2005 ） and VIP（ 1980- Oct. 2005 ）. We handsearched the related published and unpublished data and their references. The quality of included trials was evaluated. Data were extracted by two reviewers independently with a designed extraction form. RevMan 4. 2.7 software was used for data analysis. Results Twenty RCT were included with 2 624 patients. The results of meta-analysis were listed as follows： （1） stress ulcer bleeding （SUB） ： PPI （ OR 0.14,95% CI 0.08 to 0.24, NNT = 3 ） and H2RA （OR 0.24,95% CI 0.15 to 0.39, NNT =5） significantly reduced the incidence of SUB in comparison with control group. PPI significantly reduced the incidence of SUB compared with H2R.A（P 〈0. 00001 ）. （2） Mortality： PPI （OR 0.22,95% CI 0. 11 to 0.47, NNT =8） and H2RA （OR 0.53,95% CI 0. 34 to 0.81, NNT =16） significantly decreased the mortality compared with non-prophylaxis group. PPI significantly decreased the mortality compared with H2RA （OR 0.28,95% CI 0.09 to 0. 89）. （3） Adverse effect： There were not evident adverse effects in both PPI and H2RA groups. Conclusions PPI and H2RA may reduce the incidence and mortality of SUB in stroke patients, and PPls are better in reducing incidence of SUB than H2RA.
Anemia and coagulopathy are frequently presented in critically ill patients on the intensive care unit. Scientific use of blood products assist the treatment of critically ill patients. However, life-threatening adverse effects are also a risk. In 2020, the European Society of Critical Care Medicine (ESICM) published a clinical practice guideline on transfusion strategies for non-bleeding critically ill adults in an attempt to resolve the transfusion strategy problems of relevant critically ill patients. This paper interprets the key contents in order to assist Chinese clinicians for better understanding and using of the guideline.
Coronary heart disease with gastrointestinal bleeding is common in clinical practice. The disease is dangerous and has a high mortality rate. This article will review the risk factors for coronary heart disease with gastrointestinal bleeding (including Helicobacter pylori infection, long-term use of antiplatelet drugs and combined anticoagulation drugs), blood transfusion strategies (including hemoglobin transfusion thresholds and platelet transfusion strategies), and the management of antithrombotic drugs after bleeding (including the management of antiplatelet drugs and the management of anticoagulation combined with antiplatelet drugs). The purpose is to provide a theoretical basis for the diagnosis and treatment of coronary heart disease with gastrointestinal bleeding.
ObjectiveTo evaluate the safety and efficacy of unconventional abdominal drainage after laparoscopic hepatectomy.MethodsThe clinicopathologic data of patients who underwent laparoscopic hepatectomy for liver tumors in the Mianyang Central Hospital from June to December 2019 and met the inclusion criteria were retrospectively collected. Based on whether drainage tube was placed in the abdominal cavity during operation, the patients were divided into non-catheterized group (without drainage tube) and catheterized group (with drainage tube). The intraoperative data and postoperative complications (e.g. intraabdominal hemorrhage, bile leakage, abdominal infection, and liver failure) were compared between the two groups. Then, the intraoperative data and postoperative conditions of liver cancer and non-liver cancer patients with or without abdominal drainage tube were compared and analyzed.ResultsA total of 117 eligible patients were included in the study. The non-catheterized group had 59 patients and the catheterized group had 58 patients. The patients with liver cancer had 84 patients (44 non-catheterized patients and 40 catheterized patients) and the patients without liver cancer had 33 patients (15 non-catheterized patients and 18 catheterized patients). ① On the whole, the groups were comparable in the baseline data between the non-catheterized group and the catheterized group, such as gender, age, HBV infection, body mass index, hepatic function index, liver stiffness value, disease category, etc. (P>0.05). Compared with the catheterized group, the non-catheterized group had earlier off-bed activities and earlier flatus time (P<0.001), and shorter postoperative hospital stay (P=0.030). However, no statistically significant differences were found in other indicators between the two groups (P>0.05). ② Whether the patients had liver cancer or not, the non-catheterized patients still had earlier off-bed activities and earlier flatus time as compared with the catheterized patients (P<0.001). Among the patients with liver cancer, no difference was found in postoperative hospital stay. However, among the patients without liver cancer, the non-catheterized patients had shorter postoperative hospital stay than the catheterized patients (P=0.042). No statistically significant differences were found in other indicators between the catheterized patients and non-catheterized patients (P>0.05).ConclusionFor technologically skilled laparoscopic hepatectomy center, selectively not placing peritoneal drainage tube after surgery might better promote the health of patients.
Objective To find a simple, practical and cheap way in suturation to prevent incision complications after celoscope surgery. Methods Using the elastic snell needle to stitch small incision under laparoscopy. Chosed 3 120 cases using the elastic snell needle to stitch stratified suturation as research group, and 3 120 cases by using trditional arc shaped needle in celoscope surgery as control group. The incident rate of incisional hernia and incision bleeding among groups were compared. Results In research group, the incident rate of incision bleeding was 0.16%, among which was 0.15% in epigastrium group, 0.18% in hypogastrium group, while in control group, the incident rate of incision bleeding was 0.68%, among which was 0.64% in epigastrium group, 0.70% in hypogastrium group. The incident rate of incision bleeding was obviously decreased (P＜0.05), and the incident rate of incision bleeding in hypogastrium group was obviously decreased as well (P＜0.05), compared research group and control group. In research group, the incident rate of incisional hernia was 0.07%, among which was 0 in epigastrium group, 0.12% in hypogastrium group, 0.15% in gerontism group, while in control group, the incident rate of incisional hernia was 0.44%, among which was 0.24% in epigastrium group, 0.59% in hypogastrium group, 0.99% in gerontism group, and the incident rate of incisional hernia after surgery was obviously decreased (P＜0.05), the incident rate of incisional hernia after surgery in hypogastrium group was obviously decreased as well (P＜0.05), comparing research group and control group. Conclusions Using the elastic snell needle to stitch small incision under laparoscopy, the peritoneal layer and muscular layer can be apposition sutured in the case without prolonging incision and costing more, hidden hernia and abdominal wall defects located at the incision can be found, ligation and stitched, thereby the incident rate of incisional hernia and incisional bleeding after celoscope surgery are significantly reduced.
ObjectiveTo examine the intrauterine residual tissue in patients with prolonged vaginal bleeding after drug abortion by both B-ultrasound and pathology through cleaning the remnant of uterine, in order to investigate the relationship between prolonged vaginal bleeding after medical abortion with mifepristone and the residual tissues (decidua/villi). MethodsBetween June and December 2011, 144 patients with vaginal bleeding after medical abortion were involved in the study. B-ultrasound and pathology through cleaning the remnant of uterine were adopted to study the residual tissue respectively. ResultsBased on the ultrasound results, the difference in residual tissues was statistically significant between patients with bleeding for 15 days or shorter and patients with bleeding for more than 15 days (P<0.05). The pathological results showed that the difference in decidua and villi on the residual tissues was not statistically significant between patients with bleeding for 15 days or shorter and patients with bleeding for more than 15 days (P>0.05). ConclusionAfter drug abortion, the prolonged vaginal bleeding was correlated with intrauterine residual tissues, and was not correlated with whether the residual tissue was villi or decidua.
ObjectiveTo indirectly compare the efficacy and safety of bipolar radiofrequency ablation versus hysterectomy in abnormal uterine bleeding by using network meta-analysis. MethodsThe PubMed, EMbase, Web of Science, Cochrane Library, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy and safety of different surgical methods in abnormal uterine bleeding from inception to May 20, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Network meta-analysis was then performed by using Stata 16.0 software. ResultsA total of 39 RCTs involving 3 307 patients were included. The results of network meta-analysis showed that hysterectomy was superior to bipolar radiofrequency ablation in terms of amenorrhea rate and reintervention rate, while the hospital stay and patient satisfaction rate were opposite. ConclusionCurrent evidence shows that bipolar radiofrequency ablation has more advantages in terms of hospital stay and satisfaction rate, while hysterectomy has more advantages in terms of amenorrhea rate and reintervention rate. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
