ABSTRACT
Data of 643 patients who underwent endoscopic polypectomy with high-frequency electrotome in 6 hospitals of Sichuan Province between June 2020 and September 2020 were summarized. The rate of complete polypectomy and the incidence of delayed post-polypectomy bleeding (DPPB) and perforation were analyzed. DPPB occurred in 18 cases (2.80%) and postoperative perforation occurred in 1 case (0.16%). All of the 1 828 polyps were completely resected (100.0%). Univariate analysis showed that polyps′ diameter≥10 mm, long peduncle or laterally spreading tumor (LST), adenomatous polyp, endoscopic mucosal resection, mixed cutting mode 1 of electrocoagulation were significantly correlated with DPPB( P<0.05). Multivariate Logistic regression analysis revealed that polyp diameter≥10 mm ( P=0.001, OR=3.575, 95% CI: 1.175-9.955), morphology of long peduncle or LST ( P=0.004, OR=2.981, 95% CI: 1.233-14.858) were independent risk factors for DPPB. Endoscopic colorectal polypectomy with high-frequency electrotome is effective and safe. Polyps′ diameter≥10 mm, polyps with long pedicle or LST are the risk factors for DPPB.
ABSTRACT
Objective:To investigate the clinical characteristics and therapeutic methods of coronary artery aneurysm (CAA).Methods:The clinical data and coronary angiography of 32 patients confirmed by coronary angiography as coronary aneurysm in Shenzhen Hospital of Southern Medical University and Shenzhen People′s Hospital were collected. They were followed up, and the different therapeutic methods were analyzed.Results:Thirty-two cases (1.8%) of coronary artery aneurysms were found in 1 778 patients undergoing coronary angiography. The main sites of coronary ectasia were right coronary artery, anterior descending branch and circumflex branch, and the left main branch was rare. Among the patients with coronary artery aneurysms, there were 25 patients with coronary artery stenosis. All the 32 patients were given anticoagulant, antiplatelet, improvement of coronary spasm and statin therapy, among whom 2 patients were treated with stent implantation and 6 patients were treated with coronary artery bypass graft (CABG) and ligation of coronary aneurysm. During the follow-up (average 15 months) of 1 patient, acute myocardial infarction reoccurred, and coronary angiography indicated that the stenosed coronary segments after artery ectasia was occluded because of thromboembolism. In the remaining patients, there were no major cardiovascular events such as angina pectoris, acute myocardial infarction and sudden cardiac death.Conclusions:Coronary artery aneurysm is not a rare heart disease. Coronary thromboembolism, thrombosis and vasospasm are the main causes of angina pectoris and myocardial infarction. Anticoagulant, antiplatelet, antispasmodic drugs and suitable coronary artery bypass can significantly improve the clinical prognosis of patients with coronary artery aneurysm.
ABSTRACT
OBJECTIVE To evaluate risk factors of the death among lung cancer patients with nosocomial pneumonia.METHODS A total of 312 lung cancer patients with nosocomial pneumonia in our hospital were retrospectively analyzed.RESULTS Eighty-seven patients died and remaining 225 patients were cured finally.Risk factors by multivariate analysis were more than 62 years old(OR 1.75,95%CI 1.06-2.98),metastatic disease(OR 9.24,95%CI 5.21-16.17),bacteria/fungi infection(OR 2.31,95%CI 1.15-4.67),and lower serum albumin concentration(OR 1.87,95%CI 1.08-3.13).CONCLUSIONS Older,metastatic diseases,double infections and lower serum albumin concentration are the risk factors correlated with the mortality among lung cancer patients with nosocomial pneumonia.
