Comparing outcomes of single-use vs reusable ureteroscopes: a systematic review and meta analysis.

Flexible ureterolithotripsy is a frequent urological procedure, usually used to remove stones from the kidney and upper ureter. Reusable uretero-scopes were the standard tool for that procedure, but recent concerns related to sterility and maintenance and repair costs created the opportunity to develop new technologies. In 2016, the first single-use digital flexible ureteroscope was introduced.

Antibiotics prophylaxis at the time of catheter removal after radical prostatectomy: a systematic review of the literature and meta-analysis.

Purpose: To conduct a systematic literature review with meta-analysis to identify whether antibiotic prophylaxis after removal of the indwelling urinary catheter reduces posterior infections.

Methods: A systematic literature review was conducted in the databases PubMed, Embase, Cochrane, Google Scholar, and Latin American and Caribbean Health Sciences Literature, using the keywords "antibiotics" AND "prostatectomy" AND "urinary catheter."

Results: Three articles were identified having the scope of our review, with 1,040 patients, which were subjected to our meta-analysis revealing a marginally significant decrease in the risk of urinary infection after indwelling urinary catheter removal (odds ratio-OR = 0.

Does displacement of lower pole stones during retrograde intrarenal surgery improves stone-free status? A systematic review and meta-analysis.

Purpose: Kidney stones are one of the most common urological diseases worldwide. The size and location of the stone are the most important factors in determining the most suitable treatment options. The aim of this review was to evaluate the displacement of lower pole stones.

Comparing financing models for supplementary healthcare in appendectomy: activity-based costing (fee-for-service) vs. diagnosis related group remuneration (bundled payment) - a systematic review and meta-analysis.

Purpose: In Brazil, healthcare services traditionally follow a fee-for-service (FFS) payment system, in which each medical procedure incurs a separate charge. An alternative reimbursement with the aim of reducing costs is diagnosis related group (DRG) remuneration, in which all patient care is covered by a fixed amount. This work aimed to perform a systematic review followed by meta-analysis to assess the effectiveness of the Budled Payment for Care Improvement (BPCI) versus FFS.

Tamsulosin vs. Tadalafil as medical expulsive therapy for distal ureteral stones: a systematic review and meta-analysis.

Purpose: Medical expulsive therapy (MET) is recommended for distal ureteral stones from 5 to 10 mm. The best drug for MET is still uncertain. In this review, we aim to compare the effectiveness of tadalafil and tamsulosin for distal ureteral stones from 5 to 10 mm in terms of stone expulsion rate (SER), stone expulsion time (SET) and the side effect profile.

Use of artificial intelligence for sepsis risk prediction after flexible ureteroscopy: a systematic review.

Introduction: flexible ureteroscopy is a minimally invasive surgical technique used for the treatment of renal lithiasis. Postoperative urosepsis is a rare but potentially fatal complication. Traditional models used to predict the risk of this condition have limited accuracy, while models based on artificial intelligence are more promising.

Endoscopic ultrasound-guided biliary drainage: a literature review.

Neoplasms of the biliopancreatic confluence may present with obstruction of the bile tract, leading to jaundice, pruritus and cholangitis. In these cases drainage of the bile tract is imperative. Endoscopic retrograde cholangiopancreatography (ERCP) with placement of a choledochal prosthesis is an effective treatment in about 90% of cases, even in experienced hands.

EUS-guided choledochoduodenostomy for malignant biliary obstruction: A multicenter comparative study between plastic and metallic stents.

Background And Objectives: EUS-guided choledochoduodenostomy (EUS-CDS) is commonly employed to address malignant biliary obstruction (MBO) after a failed ERCP. In this context, both self-expandable metallic stents (SEMSs) and double-pigtail stents (DPSs) are suitable devices. However, few data comparing the outcomes of SEMS and DPS exist.

Palliative therapy for malignant gastric outlet obstruction: how does the endoscopic ultrasound-guided gastroenterostomy compare with surgery and endoscopic stenting? A systematic review and meta-analysis.

Introduction: The gold-standard procedure to address malignant gastric outlet obstruction (MGOO) is surgical gastrojejunostomy (SGJJ). Two endoscopic alternatives have also been proposed: the endoscopic stenting (ES) and the endoscopic ultrasound-guided gastroenterostomy (EUS-G). This study aimed to perform a thorough and strict meta-analysis to compare EUS-G with the SGJJ and ES in treating patients with MGOO.

Quality indicators in colonoscopy: observational study in a supplementary health system.

Purpose: Colorectal cancer is responsible for 9.4% of cancer deaths, and low polyp detection rate and cecal intubation rate increase the risks of interval colorectal cancer. Despite several population studies that address colonoscopy quality measures, there is still a shortage of these studies in Latin America.

DIFFICULT BILIARY CANNULATION: SHOULD WE ALWAYS TRY A SECOND ERCP AFTER A FAILED NEEDLE-KNIFE FISTULOTOMY?

Background: A successful bile duct cannulation is a prerequisite for the realization of endoscopic retrograde cholangiopancreatography (ERCP). When biliary cannulation is not possible, needle-knife fistulotomy (NKF) can be performed. However, when biliary access is not successfully achieved even after performing NKF, it is possible to interrupt the procedure, and repeat the ERCP after a short interval.

Gastrointestinal mucosal damage in patients with COVID-19 undergoing endoscopy: an international multicentre study.

Background: Although evidence suggests frequent gastrointestinal (GI) involvement during coronavirus disease 2019 (COVID-19), endoscopic findings are scarcely reported.

Aims: We aimed at registering endoscopic abnormalities and potentially associated risk factors among patients with COVID-19.

Methods: All consecutive patients with COVID-19 undergoing endoscopy in 16 institutions from high-prevalence regions were enrolled.

Robotic endoscopy. A review of the literature.

Purpose To present new endoscopic robotic devices in the context of minimally invasive procedures with high precision and automation. Methods Review of the literature by December 2018 on robotic endoscopy. Results We present the studies and investments for robotic implementation and flexible endoscopy evolution.

Choledochoduodenostomy: Outcomes and limitations.

The EUS-guided biliary drainage (EUS-BD) has gained broad acceptance as the preferred approach after failed ERCP for malignant biliary obstruction. Despite the drainage route, namely, transhepatic or transduodenal, the technical and clinical success rates are high. Because of such good outcomes with tolerable adverse events (AEs) rate, the EUS-BD might soon even replace the ERCP for primary biliary decompression in patients at high risk of failed biliary cannulation.

Background: To evaluate the effectiveness of virtual reality simulator (VRS) training compared to box-trainer training (BT) for learning outcomes in minimally invasive surgery (MIS) techniques.

Materials And Methods: A systematic review of the literature was performed using CENTRAL, MEDLINE, EMBASE, Scopus, CINAHL, LILACS. The primary outcomes were time to perform MIS and performance score in MIS.

EUS-FNA WITH 19 OR 22 GAUGES NEEDLES FOR GASTRIC SUBEPITHELIAL LESIONS OF THE MUSCLE LAYER.

Background: Tissue diagnosis is required for gastric subepithelial lesions for differential diagnosis of GISTs. However, there has not been consensus about the best needle for EUS-guided sampling of these lesions.

Aim: To evaluate the diagnostic yield of EUS-FNA for gastric subepithelial lesions of the proper muscle layer with large-bore 19 gauge needles.

Papillary fistulotomy conventional cannulation for endoscopic biliary access: A prospective randomized trial.

Aim: To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique catheter and guidewire standard access.

Methods: From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire (Group I) and papillary fistulotomy (Group II). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications (pancreatitis, bleeding, perforation) were recorded.

Endoscopic approach for management of biliary strictures in liver transplant recipients: A systematic review and meta-analysis.

Unlabelled: The most common biliary complication after liver transplantation is anastomotic stricture (AS) and it can occur isolated or in combination with other complications. Liver graft from a cadaveric donor or a living donor has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. Endoscopic treatment using balloon dilation and insertion of biliary stents by endoscopic retrograde cholangiopancreatography (ERCP) is the initial approach to these complications.

Endoscopic Ultrasonography-Guided Hemostasis Techniques.

Endoscopic ultrasonography (EUS)-guided hemostasis is an evolving technique that has the potential to improve the care of patients with refractory variceal and nonvariceal gastrointestinal bleeding. EUS-guided treatment of fundal varices with coil and/or cyanoacrylate seems to be highly effective in active bleeding, as well as for primary and secondary bleeding prophylaxis. Reports of EUS-guided treatment of refractory nonvariceal sources of bleeding are more scarce, but show high success rates.

SEDATION IN COLONOSCOPY BY USING THREE DIFFERENT PROPOFOL INFUSION METHODS AND ANALYSIS OF PLASMA CONCENTRATION LEVELS: A PROSPECTIVE COMPARATIVE STUDY.

Background: The propofolemia becomes directly linked to the clinical effects of this anesthetic and is the focus for studies comparing propofol clinical use, in different administration methods routinely used in endoscopy units where sedation is widely administered to patients.

Aim: To evaluate the effects of three different regimens of intravenous propofol infusion in colonoscopies.

Methods: A total of 50 patients that underwent colonoscopies were consecutively assigned to three groups: 1) intermittent bolus infusion; 2) continuous manually controlled infusion; 3) continuous automatic infusion.

Endoscopic stenting for inoperable malignant biliary obstruction: A systematic review and meta-analysis.

Aim: To analyze through meta-analyses the benefits of two types of stents in the inoperable malignant biliary obstruction.

Methods: A systematic review of randomized clinical trials (RCT) was conducted, with the last update on March 2015, using EMBASE, CINAHL (EBSCO), MEDLINE, LILACS/CENTRAL (BVS), SCOPUS, CAPES (Brazil), and gray literature. Information of the selected studies was extracted in sight of six outcomes: primarily regarding dysfunction, complication and re-intervention rates; and secondarily costs, survival, and patency time.

Reality named endoscopic ultrasound biliary drainage.

Endoscopic ultrasound (EUS) is used for diagnosis and evaluation of many diseases of the gastrointestinal (GI) tract. In the past, it was used to guide a cholangiography, but nowadays it emerges as a powerful therapeutic tool in biliary drainage. The aims of this review are: outline the rationale for endoscopic ultrasound-guided biliary drainage (EGBD); detail the procedural technique; evaluate the clinical outcomes and limitations of the method; and provide recommendations for the practicing clinician.
