Free Fibula Flap in Traumatic Femoral Bone Reconstruction: A 10-year Review.

Introduction: The loss of femoral bone substance represents a major therapeutic issue. When the loss of bone substance is extensive, or the local condition is unfavourable, there are few satisfactory solutions. In this study, we share our experience of large femoral bone reconstruction by free fibula flap.

NORMAL VALUES OF ESOPHAGEAL 24-HOUR IMPEDANCE-PH AMBULATORY IN AN ARGENTINE COHORT OF HEALTHY VOLUNTEERS.

Background: There are no data of reference values on 24-hour multichannel intraluminal impedance and pH (pH-MII) monitoring in Argentinian populations.

Objective: Our aim was to obtain the normal values of pH-MII variables among healthy asymptomatic volunteers in a metropolitan Health Care Center of Argentina, and to compare them with data already published from other regions around the world.

Methods: A cross-sectional study was undertaken in a tertiary referral center in Buenos Aires.

Outcomes of ulnar shortening osteotomy using a new compression plate.

Ulnar impaction syndrome (UIS) is a frequent cause of ulnar-sided wrist pain. Several open and arthroscopic surgery techniques have been described. Ulnar shortening osteotomy (USO) is often the method of choice.

A case of pyoderma gangrenosum in hand surgery.

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis that can take many clinical forms. Its diagnosis is difficult and often delayed. We report the case of a 36-year-old man with PG complicating a chemical burn of the wrist.

Development of Autologous Platelet-Rich Plasma Mixed-Microfat as an Advanced Therapy Medicinal Product for Intra-Articular Injection of Radio-Carpal Osteoarthritis: From Validation Data to Preliminary Clinical Results.

Wrist osteoarthritis (OA) is one of the most common conditions encountered by hand surgeons with limited efficacy of non-surgical treatments. The purpose of this study is to describe the Platelet-Rich Plasma (PRP) mixed-microfat biological characteristics of an experimental Advanced Therapy Medicinal Product (ATMP) needed for clinical trial authorization and describe the clinical results obtained from our first three patients 12 months after treatment (NCT03164122). Biological characterization of microfat, PRP and mixture were analysed in vitro according to validated methods.

Insertion of fully covered self-expanding metal stents in benign biliary diseases.

Introduction: Benign biliary diseases are traditionally treated using plastic stents. However, fully covered self-expanding metal stents are currently gaining acceptance for the treatment of these pathologies.

Objective: To assess the effectiveness and complications associated with the placement of temporary endoscopic fully covered self-expanding metal stents for the treatment of benign biliary diseases.

Upper limb nerve transfers: A review.

While upper limb nerve transfers were first described and performed several years ago, they have seen expanded use in the past 20 years. Initially indicated for surgical repair of brachial plexus injuries with nerve root avulsion, the indications have been extended to post-ganglionic lesions because of the excellent results of certain intraplexus nerve transfers. The traditional nerve repair techniques - primary suture and nerve grafting - form the basis of nerve surgery.

Post-ERCP pancreatitis: early precut or pancreatic duct stent? A multicenter, randomized-controlled trial and cost-effectiveness analysis.

Background: Pancreatitis is the most frequent complication due to ERCP. Pancreatic duct stent placement has been described as a preventive measure. There is also evidence pointing towards the preventive effect that early precut may provide.

Early precut is as efficient as pancreatic stent in preventing post-ERCP pancreatitis in high-risk subjects - A randomized study.

Background: The most common adverse event of endoscopic retrograde cholangiopancreatography is pancreatitis. Precut sphincterotomy has been regarded as a risk factor. Some authors have stated that early precut may actually reduce post-ERCP pancreatitis risk.

[Endoscopic ultrasound-guided choledocho-duodenostomy in advanced pancreatic cancer with duodenal obstruction].

Endoscopic retrograde cholangiopancreatography (ERCP) is considered the first-approach for biliary drainage. In cases of ERCP failure, patients are usually referred for percutaneous transhepatic biliary drainage or surgical biliary bypass. In the last decade, the indications of endoscopic ultrasound (EUS) in the management of patients with pancreatic cancer have increased, and numerous cases of EUS-guided biliary drainage have been reported in patients with failures during the ERCP.

[Hilar bile duct tumors: Endoscopic or percutaneous drainage? A prospective analysis].

Background And Objective: Both the endoscopic and the percutaneous approach are widely accepted for the drainage of hilar tumors. Our primary objective was to report on the effectiveness and complications of these procedures.

Methods: Prospective observational analysis of the endoscopic and/or percutaneous management of all hilar tumors treated at a referral hospital from October 2011 until October 2014.

[Sphincterotomy plus large balloon dilation versus sphincterotomy alone for the extraction of complex lithiasis: A prospective analysis].

Background And Purpose: Mid-size sphincterotomy associated with large balloon dilation is an alternative to wide sphincterotomy to remove complex lithiases. However, which of the two techniques is most effective remains unclear. Hence, we conducted this study to compare both methods prospectively.

[Quality and competence in endoscopic cholangiography. Towards certainty].

Introduction: The American Society of Gastroenterology (ASGE) and the American College of Gastroenterolog (ACG) have established indicators to recognize high-quality studies in endoscopic retrograde cholagiopancreatography (ERCP). The indicators were: a) Pre-procedure: adequate indication, informed consent, assessment of the degree of difficulty of the procedure and antibiotic prophylaxis. b) Intraprocedure: cannulation, choledocholithiasis extraction and stents placement rates.

[Colorectal cancer: epidemiologic characteristics in a hospital center of Rosario, Argentina].

Objective: To obtain clinical and epidemiological information that could be relevant for the purpose of screening and diagnostic strategies in colorectal cancer (CRC).

Patients And Methods: A retrospective, descriptive, observational study was performed during a three year-period at the Hospital Provincial del Centenario in Rosario, Argentina. A population of symptomatic patients referred for colonoscopic examination was evaluated after the histopathologic diagnosis of colorectal adenocarcinoma was made.
