RESUMO

BACKGROUND: Endoscopic removal of packed, large, or impacted stones, in which a basket cannot be deployed or is unable to grasp the stone(s), is challenging and inevitably leads to repeated procedures such as stent insertion and extra- or intracorporal lithotripsy. In this study, we describe the results of an alternative stone disintegration technique in a considerable series of patients using an esophageal/pyloric balloon for stone fragmentation or making working space in the bile duct to allow the deployment of the basket, a technique we call endoscopic biliary large balloon lithotripsy. METHODS: We retrieved data from 1,429 endoscopic retrograde cholangiopancreatographies (ERCPs) from 2 prospective trials performed between 2014 and 2019. Patients with difficult bile duct stones, in which a balloon dilator up to 15 mm was used to crush or increase the working space parallel to the stones in the common or hepatic duct, were included in the study. RESULTS: From the 1,429 ERCPs, 299 had difficult stones (>1 cm, impacted or multiple stones). Large balloon lithotripsy was employed in 46 cases after endoscopic papillotomy and endoscopic biliary large balloon dilation with failed attempted balloon or basket stone(s) extraction. Failure to clear the bile duct at first ERCP occurred in 4 cases (91.3% of success). Complications were observed in 5 patients (10.8%; 1 perforation, 1 pancreatitis, and 3 bleedings), who were treated conservatively. CONCLUSIONS: Large balloon lithotripsy, in order to crush the stones or make working room for baskets or balloons in the bile duct, is an effective, safe, and low cost technique for impacted, packed, or giant bile duct stones.

RESUMO

BACKGROUND AND AIMS: Linked-color imaging (LCI) is a new technology that emphasizes changes in mucosal color by providing clearer and brighter images, thus allowing red and white areas to be visualized more clearly. We investigated whether LCI increases the detection of colorectal adenomas compared with white-light imaging (WLI) and blue-laser imaging (BLI)-bright. METHODS: Consecutive patients undergoing colonoscopy were randomized (1:1:1) into examination by WLI, BLI-bright, or LCI during withdrawal of the colonoscope. The adenoma detection rate (ADR), mean number of adenomas per patient, and withdrawal time were evaluated. The lesions were evaluated according to size, morphology, location, and histology. RESULTS: A total of 379 patients were randomized, and 412 adenomas were detected. The ADR was 43.2%, 54.0%, and 56.9% for WLI, BLI-bright, and LCI, respectively, and was significantly higher in the LCI group than in the WLI group (P = .03). No significant difference was observed between LCI and BLI-bright (P = .71) or BLI-bright and WLI (P = .09). The mean number of adenomas per patient was 0.82, 1.06, and 1.38 for WLI, BLI-bright, and LCI, respectively, with a significant difference between LCI and WLI (P = .03). Withdrawal time did not differ among the groups. A total of 102 adenomas were detected by WLI, 131 by BLI-bright, and 179 by LCI. LCI provided a higher rate of detection of adenomas ≤5 mm in size than WLI (P = .02), with a borderline significance for a higher detection of sessile serrated adenomas (P = .05). Nonpolypoid adenomas were more commonly located in the right colon segment and polypoid adenomas in the left colon segment, with a significant difference only between BLI-bright (P < .01) and LCI (P = .03). CONCLUSIONS: Our findings show that LCI increases the detection of colorectal adenomas during colonoscopy. (Clinical trial registration number: RBR-9xg6dx.).

RESUMO

OBJECTIVES:: The removal of pre-malignant colorectal lesions prevents cancer. Hyoscine has been proposed as a means of improving diagnosis by reducing colonic movements. The aim of this study was to analyze whether this anti-spasmodic enhances the detection of pre-malignant colorectal lesions. METHODS:: In a randomized, double-blinded fashion patients received hyoscine or a saline solution in all consecutive colonoscopies in which the cecum was reached. Lesions were analysed with respect to number, size, location, histology and capillary pattern. RESULTS:: A total of 440 colonoscopies were randomized. The overall polyp detection rate (PDR) and the adenoma detection rate (ADR) were 65.2% and 49.3%, respectively. In the hyoscine group, non-polypoid lesions were detected significantly more often (p=0.01). In the placebo group 281 lesions were diagnosed (202 adenomas) and in the hyoscine group 282 lesions were detected (189 adenomas) (p=0.23). The PDR and ADR were similar between the placebo and hyoscine groups (64% vs 66% and 50% vs 47%, respectively). No differences were observed between the two groups in the advanced-ADR or advanced neoplasia detection rate, as well the mean numbers of polyps, adenomas, advanced adenomas and advanced neoplasias detected per patient. The administration of hyoscine also did not improve the diagnostic accuracy of digital chromoendoscopy. The presence of adenomatous polyps in the right colon was detected significantly more frequently in the hyoscine group (OR 5.41 95% CI 2.7 - 11; p<0.01 vs OR 2.3 95% CI 1.1 - 4.6; p=0.02). CONCLUSION:: The use of hyoscine before beginning the withdrawal of the colonoscope does not seem to enhance the PDR and the ADR.

RESUMO

Background Acute pancreatitis is the most common complication after ERCP, occurring in about 4 % of the procedures. Only the placement of pancreatic duct prosthesis and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) have shown benefit in the prevention of post-ERCP pancreatitis (PEP). Although the benefit of rectal administration of indomethacin or diclofenac is recommended by some studies and society guidelines especially in a selected group of high-risk patients, there is so far, no standardization of time or route of NSAID administration. The aim of the current study is to investigate the role of an intravenous NSAID administered before the procedure for PEP prevention. Methods In this randomized double-blind clinical trial, all consecutive patients who underwent ERCP were randomized to receive saline infusion with ketoprofen or saline, immediately before the procedure. Results A total of 477 patients were enrolled and completed follow-up. The majority of patients (72.1 %) had bile duct stones, and only 1.5 % had a clinical suspicion of sphincter of Oddi dysfunction. PEP developed in 5 of 253 (2 %) patients in the placebo group and in 5 of 224 (2.2 %) patients in the ketoprofen group (p = 1.). Conclusions Intravenous administration of ketoprofen immediately prior to ERCP did not result in reduction in PEP in a general population of ERCP patients.
