Objective To systematically evaluate the effectiveness and safety of China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding. Methods Such databases as PubMed, MEDLINE, Springer, The Cochrane Library, CNKI, VIP, CBM and WanFang data were searched to collect the randomized controlled trials (RCTs) about China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding, and the references of included studies were also retrieved. The retrieval time was from inception to December 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.1 software. Results A total of 11 RCTs were included. Among all 1 075 patients, 544 were in the treatment group, while the other 531 were in the control group. The results of meta-analysis showed that, there were no significant differences in the total effective rate (OR=0.68, 95%CI 0.35 to 1.33, P=0.26) and safety (RR=1.33, 95%CI 0.45 to 3.91, P=0.96) between the China-made omeprazole and imported omeprazole. Conclusion China-made omeprazole is effective and safe in treating acute non-variceal upper gastrointestinal bleeding in comparison with the imported omeprazole.
Objective To discuss the common clinical problems and make the individualized treatment for a patient with obscure gastrointestinal bleeding by means of evidence-based medicine, so as to ultimately control the symptoms and reduce the mortality. Methods After the clinical problems were put forward, the systematic reviews and randomized controlled trials (RCTs) were collected in The Cochrane Library (online), MEDLINE, EMBase, SCIE and CNKI databases, from the date of their establishment to 2010. The treatment protocol was made by combining the assessment of evidence with the willingness of both patient and relatives. Results A total of 30 RCTs and 5 systematic reviews were identified. A rational diagnostic and therapeutic plan was made upon a serious evaluation of the data and willingness of patients. The Mickel’s diverticulum was found through capsule endoscopy, which was then locally excised under laparoscopy. After a 6-month follow-up, the plan proved to be optimal. Conclusion The treatment efficacy in diagnosed obscure gastrointestinal bleeding has been improved by adopting an individualized treatment plan according to evidence-based methods.
【Abstract】 Objective To evaluate the detection and localization of obscure lower gastrointestinal bleeding by using SPECT/CT and intraoperative endoscopy. Methods Twenty-six cases of patients with obscure lower gastrointestinal bleeding were analyzed retrospectively. Results The positive detection rate of SPECT/CT was 88.5%. All 26 patients (100%) were identified the bleeding source by using intraoperative endoscopy. No recurrence was found during 1-24 months follow-up. Conclusion SPECT/CT examination should be chosen firstly for patients with obscure lower gastrointestinal bleeding in order to localize the bleeding site roughly. Intraoperative endoscopy can localize the bleeding site accurately in patients who undergoes operation.
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.
Acute nonvariceal upper gastrointestinal bleeding (ANVUGIB) is one of the most common emergencies of the digestive system. With the continuous development of digestive endoscopy technology and widespread use of proton pump inhibitors, the morbidity and mortality of ANVUGIB have declined, but there are still numerous difficulties to be solved in clinical treatment. The International Consensus Group in 2019 updated the international consensus guideline in 2003 and 2010 with new clinical recommendations on fluid resuscitation, risk assessment, pre-endoscopic treatment, endoscopic treatment, drug therapy, and secondary prevention, etc. This paper interprets the update to provide references for the clinical treatment of ANVUGIB.
Objective To investigate the effect of emergency fast-track treatment on dangerous upper gastrointestinal bleeding. Methods Seventy-six patients who received traditional treatment between October 2020 and March 2021 were included in the traditional treatment group, and 82 patients who entered the emergency fast track for dangerous upper gastrointestinal bleeding between April 2021 and September 2021 were included in the fast-track treatment group. The patients in the traditional treatment group were treated with the traditional single-subject diagnosis and treatment mode, and the patients in the fast-track treatment group were treated according to the multidisciplinary diagnosis and treatment procedures of emergency fast track for dangerous upper gastrointestinal bleeding. The length of emergency stay, 24-hour endoscopic completion rate, effective rate, and length of hospital stay were compared between the two groups. Results The length of emergency stay [(3.75±3.19) vs. (6.51±4.72) h], the effective rate (96.3% vs. 85.5%) and the length of hospital stay [(8.26±2.51) vs. (11.07±2.79) d] were significantly better in the fast-track group than those in the traditional treatment group (P<0.05). There was no significant difference in the 24-hour endoscopic completion rate between the two groups (96.3% vs. 96.1%, P>0.05). Conclusion Compared with the traditional treatment mode, the fast-track treatment mode can significantly improve the treatment efficiency, and reduce the lengths of emergency stay and hospital stay.
Objective To investigate the risk factors for postoperative gastrointestinal bleeding (GIB) in patients with type A aortic dissection, and further discuss its prevention and treatment. Methods The clinical data of patients with type A aortic dissection admitted to the Department of Cardiovascular Surgery of the First Affiliated Hospital of Naval Medical University from 2017 to 2021 were retrospectively analyzed. Patients were divided into a GIB group and a non-GIB group based on the presence of GIB after surgery. The variables with statistical differences between two groups in univariate analysis were included into a multivariate logistic regression model to analyze the risk factors for postoperative GIB in patients with type A aortic dissection. Results There were 18 patients in the GIB group including 12 males and 6 females, aged 60.11±10.63 years, while 511 patients in the non-GIB group including 384 males and 127 females, aged 49.81±12.88 years. In the univariate analysis, there were statistical differences in age, preoperative percutaneous arterial oxygen saturation (SpO2)<95%, intraoperative circulatory arrest time, postoperative low cardiac output syndrome, ventilator withdrawal time>72 hours, postoperative FiO2≥50%, continuous renal replacement therapy (CRRT) rate, extracorporeal membrane oxygenation (ECMO) rate, infection rate, length of hospital stay and ICU stay, and in-hospital mortality (all P<0.05). In the multivariate logistic regression analysis, preoperative SpO2<95% (OR=10.845, 95%CI 2.038-57.703), ventilator withdrawal time>72 hours (OR=0.004, 95%CI 0.001-0.016), CRRT (OR=6.822, 95%CI 1.778-26.171) were risk factors for postoperative GIB in patients (P≤0.005). In the intra-group analysis of GIB, non-occlusive mesenteric ischemia (NOMI) accounted for 38.9% (7/18) and was the main disease type for postoperative GIB in patients with type A aortic dissection. Conclusion In addition to patients with entrapment involving the superior mesenteric artery who are prone to postoperative GIB, preoperative SpO2<95%, ventilator withdrawal time>72 hours, and CRRT are independent risk factors for postoperative GIB in patients with type A aortic dissection. NOMI is a major disease category for GIB, and timely diagnosis and aggressive treatment are effective ways to reduce mortality. Awareness of its risk factors and treatment are also ways to reduce its incidence.
