A.- Endoscopic ultrasonography guided drainage: Summary of consortium meeting, May 21, 2012, San Diego, California(2015) KAHALEH, Michel; ARTIFON, Everson L. A.; PEREZ-MIRANDA, Manuel; GAIDHANE, Monica; RONDON, Carlos; ITOI, Takao; GIOVANNINI, MarcEndoscopic retrograde cholangiopancreatography ( ERCP) is the preferred procedure for biliary and pancreatic drainage. While ERCP is successful in about 95% of cases, a small subset of cases are unsuccessful due to altered anatomy, peri-ampullary pathology, or malignant obstruction. Endoscopic ultrasound-guided drainage is a promising technique for biliary, pancreatic and recently gallbladder decompression, which provides multiple advantages over percutaneous or surgical biliary drainage. Multiple retrospective and some prospective studies have shown endoscopic ultrasound-guided drainage to be safe and effective. Based on the currently reported literature, regardless of the approach, the cumulative success rate is 84%-93% with an overall complication rate of 16%-35%. endoscopic ultrasound-guided drainage seems a viable therapeutic modality for failed conventional drainage when performed by highly skilled advanced endoscopists at tertiary centers with expertise in both echo-endoscopy and therapeutic endoscopy
- Surgery or EUS-guided choledochoduodenostomy for malignant distal biliary obstruction after ERCP failure(2015) ARTIFON, Everson L. A.; LOUREIRO, Jarbas F.; BARON, Todd H.; FERNANDES, Kaie; KAHALEH, Michel; MARSON, Fernando P.Background and Objectives: Endoscopic retrograde cholangiopancreatography (ERCP) is the method of choice for drainage in patients with distal malignant biliary obstruction, but it fails in up to 10% of cases. Percutaneous transhepatic cholangiography (PTC) and surgical bypass are the traditional drainage alternatives. This study aimed to compare technical and clinical success, quality of life, and survival of surgical biliary bypass or hepaticojejunostomy (HJT) and endoscopic ultrasound (EUS)-guided choledochoduodenostomy (CDT) in patients with distal malignant bile duct obstruction and failed ERCP. Patients and Methods: A prospective, randomized trial was conducted. From March 2011 to September 2013, 32 patients with malignant distal biliary obstruction and failed ERCP were studied. The HJT group consisted of 15 patients and the CDT group consisted of 14 patients. Technical and clinical success, quality of life, and survival were assessed prospectively. Results: Technical success was 94% (15/16) in the HJT group and 88% (14/16) in the CDT group (P = 0.598). Clinical success occurred in 14 (93%) patients in the HJT group and in 10 (71%) patients in the CDT group (P = 0.169). During follow-up, a statistically significant difference was seen in mean functional capacity scores, physical health, pain, social functioning, and emotional and mental health aspects in both techniques (P < 0.05). The median survival time in both groups was the same (82 days). Conclusion: Data relating to technical and clinical success, quality of life, and survival were similar in patients who underwent HJT and CDT drainage after failed ERCP for malignant distal biliary obstruction.

A.- Endoscopic ultrasound-guided fine-needle aspiration for the diagnosis of kidney lesions: A review(2015) LOPES, Roberto Iglesias; MOURA, Renata Nobre; ARTIFON, EversonTraditionally, treatment of renal lesions is indicated based only on imaging features. Although controversy exists about tissue sampling from small renal masses, renal biopsy is indicated in some cases. In this review, we discuss the rationale for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and summarize the recent advances in this field, providing recommendations for the practicing clinician. The use of EUS-FNA appears to be a safe and feasible means of confirming or excluding malignancy. EUS allows assessment and biopsy of masses or lesions within both kidneys and related complications are rare. The main advantages of EUS-FNA are that it can be done as an outpatient procedure, with good results, minimal morbidity and a short hospital stay. Nevertheless, EUS-FNA of renal masses should be indicated only in selected cases, in which there is potential to decrease unnecessary treatment of small renal masses and to best select tumors for active surveillance and minimally invasive ablative therapies. Additionally, some renal lesions may be ineligible for EUS-guided biopsy because of anatomical limitations. EUS-FNA renal biopsy will probably be best applied to central anterior renal masses, while tumors on the posterior aspect of the kidney, percutaneous access will probably be superior.
