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 assess the value of endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) for diagnosis of extrahepatic bile duct lesions. Methods A retrospective analysis was performed on the data of 11 patients with extrahepatic bile duct lesions undergoing EUS-FNA in the Third People′s Hospital of Chengdu between January 2012 and December 2016. The result of biopsy was compared with that of surgical finding and follow-up study. Results EUS-FNA was successfully performed on 11 patients with 1 lesions in proximal bile duct, 6 in distal bile duct, and 4 in ampulla. According to the results of biopsy, 7 lesions were pathologically confirmed as adenocarcinoma, 1 was suspicious of adenocarcinoma, 1 couldn′t be excluded as carcinoma, and 2 were considered to be benign. Compared with the results of surgical pathology and follow-up study, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of EUS-FNA in diagnosis of extrahepatic bile duct lesions were 89%(8/9), 100%(2/2), 91%(10/11), 100%(8/8), and 67%(2/3), respectively. One case suffered mild pancreatitis after EUS-FNA without other complications. Conclusion EUS-FNA is a safe, feasible and effective method for diagnosis of lesions in extrahepatic bile duct.
ABSTRACT
Objective To evaluate the clinical application of transendoscopic Doppler ultrasonogra-phy in various gastrointestinal diseases. Methods Transendoscopic Doppler ultrasonography was performed in 59 patients with various gastrointestinal diseases. Results The Doppler signals were detected beneath the peptic ulcer base in 29 of 39 patients (74. 4% ) . For acute ulcer bleeding and non - bleeding, the Doppler - positive rates were 87. 5% and 65. 2% , respectively, and the measured depth of vessels were 0. 49 mm and 0. 65mm (P
