Postoperative complications and waiting time for surgical intervention after radiologically guided drainage of intra-abdominal abscess in patients wi…

2021

Abstract Background In patients with active Crohn’s disease (CD), treatment of intra-abdominal abscess usually comprises antibiotics and radiologically guided percutaneous drainage (PD) preceding surgery. The aim of this study was to investigate the risk of postoperative complications and identify the optimal time interval for surgical intervention after PD. Methods A multicentre, international, retrospective cohort study was carried out. Details of patients with diagnosis of CD who underwent ultrasonography- or CT-guided PD were retrieved from hospital records using international classification of disease (ICD-10) diagnosis code for CD combined with procedure code for PD. Clinical variable…

Bayesian hierarchical nonlinear modelling of intra-abdominal volume during pneumoperitoneum for laparoscopic surgery

2021

Laparoscopy is an operation carried out in the abdomen or pelvis through small incisions with external visual control by a camera. This technique needs the abdomen to be insufflated with carbon dioxide to obtain a working space for surgical instruments' manipulation. Identifying the critical point at which insufflation should be limited is crucial to maximizing surgical working space and minimizing injurious effects. Bayesian nonlinear growth mixed-effects models are applied to data coming from a repeated measures design. This study allows to assess the relationship between the insufflation pressure and the intra--abdominal volume.

Visceral fat area as a new independent predictive factor of survival in patients with metastatic renal cell carcinoma treated with antiangiogenic age…

2011

Abstract Purpose. A better identification of patients who are more likely to benefit from vascular endothelial growth factor–targeted therapy is warranted in metastatic renal cell carcinoma (mRCC). As adipose tissue releases angiogenic factors, we determined whether parameters such as visceral fat area (VFA) were associated with outcome in these patients. Experimental Design. In 113 patients with mRCC who received antiangiogenic agents (bevacizumab, sunitinib, or sorafenib) (n = 64) or cytokines (n = 49) as first-line treatment, we used computed tomography to measure VFA and subcutaneous fat area (SFA). We evaluated associations linking body mass index (BMI), SFA, and VFA to time to progres…

La Sindrome Compartimentale Addominale (ACS) dopo chirurgia dell'Aneurisma dell'Aorta Addominale (AAA)

2009

Introduction: The Abdominal Compartment Syndrome (ACS) is a “condition in which increased tissue pressure in a confined anatomic space, causes decreased blood flow leading to ischaemia and dysfunction and may lead to permanent impairment of function” Materials and Methods: between june 2007 and june 2008 we treated surgically 23 cases of AAA (14 in election and 9 in emergency), with indirect intra-abdominal pressure (IAP) monitoring (intra-vescical catheter). Mean age was 68 (64-84) years. Mean transverse diameter was 6,2 cm (min 5,5 e max 9,0). Rise in IAP more then 20 mmHg was considered for surgical decompression. In 1 case we registered preoperatively IAP more than 20 mmHg treated with …

Body composition with dual energy X-ray absorptiometry: from basics to new tools

2020

Dual-energy X-ray absorptiometry (DXA) in nowadays considered one of the most versatile imaging techniques for the evaluation of metabolic bone disorders such as osteoporosis, sarcopenia and obesity. The advantages of DXA over other imaging techniques are the very low radiation dose, its accuracy and simplicity of use. In addition, fat mass (FM) and lean mass (LM) values by DXA shows very good accuracy compared to that of computed tomography and magnetic resonance imaging. In this review we will explain the technical working principles of body composition with DXA, together with the possible limitations and pitfalls that should be avoided in daily routine to produce high-quality DXA examina…

Síndrome compartimental abdominal y síndrome de distrés intestinal agudo

2013

Seriously ill patients frequently present intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) as complications, and the associated mortality is very high. This review offers an update on the most controversial aspects of these entities: factors favoring their appearance, the most common causes, prognosis, and methods of measuring intra-abdominal pressure (IAP), physiopathological consequences in relation to the different organs and systems, and the currently accepted treatment measures (medical and/or surgical). Simultaneously to the strictly physical mechanisms of injury, such as direct compression of intra-abdominal organs and vessels, the transmission of IAP to ot…

Global validation of the WSES Sepsis Severity Score for patients with complicated intra-abdominal infections : a prospective multicentre study (WISS …

2015

BACKGROUND: To validate a new practical Sepsis Severity Score for patients with complicated intra-abdominal infections (cIAIs) including the clinical conditions at the admission (severe sepsis/septic shock), the origin of the cIAIs, the delay in source control, the setting of acquisition and any risk factors such as age and immunosuppression. ----- METHODS: The WISS study (WSES cIAIs Score Study) is a multicenter observational study underwent in 132 medical institutions worldwide during a four-month study period (October 2014-February 2015). Four thousand five hundred thirty-three patients with a mean age of 51.2 years (range 18-99) were enrolled in the WISS study. ----- RESULTS: Univariate…

Leisure-time physical activity and intra-abdominal fat in young adulthood: A monozygotic co-twin control study

2016

Objective To investigate differences in abdominal fat compartments between young adult monozygotic twin pairs discordant for leisure-time physical activity. Methods Ten young adult male monozygotic twin pairs (age range 32-36 years) discordant for leisure-time physical activity during the past 3 years were systematically selected from a population-based Finnish twin cohort. Magnetic resonance image at the level of the L2-L3 intervertebral disc was used to predict intra-abdominal and subcutaneous abdominal fat masses. Dietary intake was assessed with a 4-day food diary. Results Inactive twins had 31% more intra-abdominal fat than their active co-twins (mean difference 0.52 kg, 95% CI 0.12 to…

Vacuum-Assisted Abdominal Closure in Surgical Emergency: A Single Institution Experience Treating a Cohort with a Prevalence of Faecal Peritonitis

2021

Abstract Vacuum-assisted abdominal closure (VAAC) has evolved as a promising method for treatment of emergent surgical patients. The aim of the study was an assessment of the complication rate and outcomes following routine application of VAAC in a cohort of patients suffering predominantly with peritonitis of the lower gastrointestinal tract (GIT) origin. The prospectively collected data was analysed retrospectively, including demographic data, aetiological factors, comorbid conditions and severity of the disease. The indications for VAAC included complicated intra-abdominal infection, purulent peritonitis with sepsis and/or risk of increased intra-abdominal pressure. In total, 130 patient…
