Appendectomy versus conservative treatment with antibiotics for patients with uncomplicated acute appendicitis: a propensity score-matched analysis of patient-centered outcomes (the ACTUAA prospective multicenter trial).

Purpose: The aim of this prospective multicenter study was to compare antibiotic therapy and appendectomy as treatment for patients with uncomplicated appendicitis confirmed by ultrasound and/or computed tomography.

Methods: The study was conducted from January 2017 to January 2018. Data regarding all patients discharged from the participating centers with a diagnosis of uncomplicated appendicitis were collected prospectively.

Predictive Factors of Intestinal Necrosis in Acute Mesenteric Ischemia.

Objectives: Acute mesenteric ischemia (AMI) is a gastrointestinal and vascular emergency in which the detection of patients requiring intestinal resection is mandatory.

Methods: Registered data of 55 consecutive patients admitted to our center between January 2010 and December 2016 that underwent an explorative laparotomy for a suspected diagnosis of irreversible transmural intestinal necrosis (ITIN) were analyzed. Demographic, clinical, laboratory and CT findings were statistically analyzed in order to search predictive factors of ITIN and their correlation to its clinical spectre.

Efficacy and safety of ultrasound-guided placement of central venous port systems via the right internal jugular vein in elderly oncologic patients: our single-center experience and protocol.

Background: Ultrasound-guidance has become the routine method for internal jugular vein (IJV) catheterization reducing dramatically failure and complication rates for central venous port (CVP) placement.

Aims: The aim of this study was to determine the safety and efficacy of ultrasound-guided IJV CVP placement in elderly oncologic patients.

Methods: Between January 2013 and December 2015, 101 elderly oncological patients underwent right IJV CVP placement under ultrasound-guidance.
