ObjectiveTo assess the effect of chewing gum on the recovery of postoperative gastrointestinal function in patients with colorectal cancer. MethodsA comprehensive search for relevant randomised controlled trials (RCTs) was conducted in domestic and international databases such as PubMed, The Cochrane Library, Web of Science, Chinese Science and Technology Journal Full-text Database, Chinese Periodicals Full-text Database, Wanfang data, and other databases, with a timeframe up to September 2023. The literature was screened according to the inclusion and exclusion criteria. Simultaneously, the literature quality evaluation and data extraction were performed. The continuous variables were described using mean difference (95% confidence interval) and the binary variables were described using odds ratio (95% confidence interval). Test level was α=0.05. ResultsA total of 28 RCTs covering 2 523 postoperative colorectal cancer patients were included. The meta-analysis results showed that the postoperative chewing gum could shorten the time of the first flatus [–11.99 (–14.45, –9.53)], the first defecation [–18.79 (–23.58, –14.00)], the first bowel sounds [–6.35 (–6.64, –6.06)] or the first starvation [–5.20 (–10.11, –0.28)], and the hospital stay [–1.35 (–1.99, –0.70)], as well as could increase the serum gastrin level [23.70 (14.88, 32.53)]. Furthermore, it also could decrease the incidence of postoperative complications, such as nausea [0.66 (0.48, 0.91)], abdominal distension [0.48 (0.35, 0.67)], and intestinal obstruction [0.34 (0.20, 0.59)]. However, there was a non-significant effect on vomiting [0.81 (0.60, 1.09)] or time of the first oral intake [–0.67 (–1.99, 0.65)]. ConclusionsFrom the results of this meta-analysis, postoperative gum chewing aids to promote the recovery of gastrointestinal function and reduce the risk of postoperative complications in colorectal cancer patients. Although further studies are needed to verify the long-term effects and the feasibility of clinical application, the results of this study provide an important empirical support for the utilize of chewing gum in the management of postoperative gastrointestinal function.
ObjectiveThis study was aimed to evaluate the clinical efficacy of mechanical thrombectomy using the AngioJet System for the treatment of lower extremity acute arterial embolism and thrombosis.MethodsThe clinical data of 20 patients with acute lower extremity arterial embolism and thrombosis admitted to the Department of Vascular Surgery in the People’s Hospital in Gansu Province where the author worked from September 2016 to March 2017, were retrospectively analyzed. All patients were treated with the AngioJet mechanical thrombectomy system. Clinical data of the patients were retrospectively collected. The clinical efficacy of AngioJet mechanical thrombectomy wasanalyzed.ResultsEighteen (90.0%) of the 20 patients successfully completed the mechanical thrombectomy by using the AngioJet System. The mean time for hospital stay and operation was (4.2±1.4) d and (1.3±0.4) h, respectively. The average doses of urokinase and heparin during operation were (35.80±12.30) ×104 U and (45.10±8.30) mg, respectively. Two patients received a complementary treatment of incision for removing the thrombus. Two patients received catheter-directed thrombolysis after the mechanical thrombectomy, 5 patients received bare-metal stent implantation after balloon expansion. Clinical success was in 16 cases. According to the Cooley standard, 10 patients were in excellent condition,6 in good condition, 2 in fair condition, and 2 in poor condition. There were 2 cases of distal arterial embolization,2 cases of antecardial discomfort of bradycardia, and 4 cases of bleeding at the puncture point, but no serious bleeding complications such as gastrointestinal and intracranial hemorrhage occurred. A total of 16 patients presented myoglobinuria during and after operation. All patients were followed up for 6–12 months. The results of ultrasound examination showed that the artery was patency in 15 cases. One patient died of myocardial infarction in 9 months after surgery,2 patients developed lower extremity ischemia symptoms again after surgery, and 2 patients had lower extremity ulcer caused by lower extremity ischemia symptoms. During the follow-up period, no lower limb necrosis, amputation, and death occurred in the remaining patients.ConclusionsThe AngioJet mechanical thrombectomy system is safe and effective. Combined with the use of catheter-directed thrombolysis and stent implantation, the AngioJet mechanical thrombectomy could lead to quick recovery of the perfusion of the lower extremity and improve the limb salvage rates, exhibiting excellent clinical value.
ObjectiveTo evaluate the efficacy and safety of intracavitary treatment for iliac vein compression syndrome（IVCS）with acute lower extremity deep venous thrombosis (DVT).MethodsThe clinical data of 57 patients with IVCS and lower extremity DVT, who undergoing with stent implantation, balloon expansion and Angiojet rheolytic thrombectomy from June 2015 to June 2018, were retrospectively analyzed. The effect of treatment was evaluated by the changes of thigh circumference difference between the affected side and the healthy side, and the thrombosis clearance rate in the operating. In addition, the incidence of post-thrombotic syndrome (PTS) and stent patency rate were analyzed after long-term follow-up based on the change of Villaita scale score and ultrasound examination of lower extremity veins.ResultsThe success rate of surgical technique was 100%, and there was no pulmonary embolism during operating and postoperative. Lower extremity deep vein thrombosis clearance levels Ⅲ 48 cases (84.2%), Ⅱ 9 cases (15.8%), the changes of thigh circumference difference between the affected side and the healthy side from preoperative (5.8±1.7) cm to (3.7±1.0) cm. One year follow-up after operation, the primary patency rate of stent was 86.0% and PTS occurred in 8 patients (14.0%).ConclusionStent implantation, balloon expansion and Angiojet rheolytic thrombectomy for IVCS with acute lower extremity DVT is a safe, effective with low incidence of complications and efficient thrombus clearance.
ObjectiveTo review the current status of case studies on drug comprehensive clinical evaluation published in China in the past decade, providing references for the standardized implementation of evaluation. MethodsA scoping review was conducted on the published cases of drug comprehensive clinical evaluation in China. The analysis was carried out from themes, dimensions, methods, and quality control. Descriptive analysis was used to analyze the evaluation themes, dimension, method, and quality control of the included studies. Meanwhile, VOSviewer 1.6.20 software was used to conduct co-occurrence network analysis of author's affiliation and evaluation dimensions. ResultsThe research on comprehensive drug clinical evaluation has developed the fastest in Beijing. Medical institutions, universities, and scientific institutions are the main research institutions. Universities and their affiliated hospitals have stronger collaboration, while some local hospitals show research isolation. The evaluation themes focus on chronic diseases and cancer, with some repetitions. The evaluation methods mainly rely on descriptive analysis. In nearly half of the cases, evidence-based medicine methods are inadequately applied. Only about 5% of the cases have conducted real-world research. For cases with the same theme, results may conflict due to differences in methods or data sources. The value integration mainly relies on quantitative scoring, which is lacking in 37.05% cases. Only 14.03% of the cases report quality control. In 31.87% of cases, the data provided by pharmaceutical companies were used, with a lack of conflict-of-interest disclosures. ConclusionAlthough the comprehensive clinical evaluation of drugs in China has developed rapidly, there are problems such as non-standardized methods and differences in data sources. It is necessary to improve the scientificity and decision-making value of evaluation results by coordinating theme selection, strengthening quality control, and developing reporting guideline.
