RESUMEN
@#Objective To systematically evaluate the safety, efficacy, and economics of intracardiac echocardiography (ICE) versus transesophageal echocardiography (TEE) in left atrial appendage occlusion (LAAO). Methods PubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Database were systematically searched to collect relevant studies on comparing ICE and TEE-guided LAAO from inception to June 15th, 2022. Two reviewers independently screened the literatures, extracted the data, and assessed the risk of bias of the included studies. Meta-analyses were performed using RevMan 5.3 and R 4.0.3. Retrospective cohort studies were excluded for sensitivity analysis. Subgroup analyses were performed based on the types of occluder and ICE catheter. Results A total of 14 studies with 6 599 patients were included. Meta-analyses showed no statistical differences in technical success rate, overall complications, device embolization, peri-device leakage, device-related thrombus, stroke, vascular complications, bleeding, operation time, fluoroscopy time, or contrast agent volume between the ICE and TEE-guided LAAO. The total in-room time (MD=–33.47 min, 95%CI –41.20 to –25.73, P<0.000 01) and radiation dosage (MD=–170.20 mGy, 95%CI –309.79 to –30.62, P=0.02) were lower in the ICE group than those in the TEE group, whereas the incidence of pericardial effusion/tamponade was higher than the TEE group (RR=1.57, 95%CI 1.01 to 2.45, P=0.048). Except for pericardial effusion/tamponade, subgroup analyses and sensitivity analysis showed similar results. The analysis based on the cost data from the United States showed comparable or even lower total costs for ICE versus TEE, but comparative domestic cost studies were lacking. Conclusion Current evidence suggests that ICE-guided LAAO can reduce radiation dosage and total in-room time, and there is no statistical difference in the overall complication rate between the two groups. Owing to the limitations of sample size and quality of the included studies, the conclusion still needs to be verified by large sample size and high-quality randomized controlled trials.
RESUMEN
Objective To observe the near future curative effect and toxicity of the combination of weekly dose of cisplatin in the treatment of elderly patients with esophageal cancer intensity-modulated radiotherapy observa-tion.Methods 60 patients with locally advanced esophageal cancer patients aged by method randomly were divided into synchronous chemotherapy group( CRT group) and 30 cases of radiotherapy alone group( RT group) 30 cases,the two groups using 6MV-X ray intensity modulated radiotherapy,radiotherapy dose:DT 60 Gy/30/6 week.The CRT treated group was given cisplatin 20-25mg/m2 in the radiotherapy of second day,1 times per week,a total of 6 times. Results Radiotherapy and chemotherapy, radiotherapy group recent effective rate were 80.0% and 63.3%, the difference was statistically significant(χ2 =5.934,P0.05). Conclusion Intensity modulated radiotherapy combined with weekly dose of cisplatin in the treatment of elderly patients with esophageal cancer significant short-term effect,less adverse reactions,patient tolerance is good,which is worth the clinical promotion.
