USEFULNESS OF CT COLONOGRAPHY IN PATIENTS WITH OCCLUSIVE COLORECTAL CANCER BEFORE METALLIC STENT PLACEMENT: A SINGLE ENTER EXPERIENCE

2015

Up to 15% of patients with colorectal cancer (CRC) present with large bowel obstruction. Currently, computed tomography colonography (CTC) is regarded as a promising technique for complete evaluation of the proximal colon and simultaneous assessment of extraluminal status. Aim of this retrospective, observational study is to evaluate the feasibility of using CTC for preoperative examination of the proximal colon before metallic stgent placement in patients with colon obstruction caused by CRC. Sixteen patients who demonstrated colonic obstruction caused by CRC, underwent CTC immediately after incomplete colonoscopy. Per-patient sensitivity of CTC for lesion 5 mm larger in diameter in the co…

Probiotics, prebiotics and symbiotics in inflammatory bowel diseases: state-of-the-art and new insights

2013

Inflammatory bowel disease (IBD) consists of two distinct clinical forms, ulcerative colitis (UC) and Crohn's disease (CD), with unknown aetiology, which nevertheless are considered to share almost identical pathophysiological backgrounds. Up to date, a full coherent mechanistic explanation for IBD is still lacking, but people start to realize that the pathogenesis of IBD involves four fundamental components: the environment, gut microbiota, the immune system and the genome. As a consequence, IBD development might be due to an altered immune response and a disrupted mechanism of host tolerance to the non-pathogenic resident microbiota, leading to an elevated inflammatory response. Consideri…

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

2021

Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…

FOCAL ACTIVE COLITIS AS A PREDICTOR OF INFLAMMATORY BOWEL DISEASE: RESULTS FROM A SINGLE-CENTER EXPERIENCE.

2017

The term focal active colitis (FAC) is conventionally used to describe the presence of isolated cryptitis, characterized by an inflammatory infiltrate consisting of intraepithelial neutrophils and/or neutrophils invading the lumen of the criptae, with no other microscopic alteration of the colonic mucosa and, in particular, without the presence of signs of chronic inflammation. To date, only four studies, including one conducted in a pediatric population, have been performed to evaluate the clinical significance of this disease. The aim of this retrospective study on prospectively-collected data is to evaluate the clinical implications of the focal active colitis, since there still remains …

A rare complication of ERCP: Mallory-Weiss syndrome

2005

OBJECTIVE: To describe the management and outcome after endoscopic treatment of hematemesis by Mallory-Weiss Syndrome (MWS) occurred after CPRE (suspected choledocolithiasis). Background data: Although cough and retching is common during EGD or CPRE, MWS resulting from endoscopy seems to be uncommon (0.0001-0.04%) and always self-limiting. Case report: The patient was submitted to CPRE with the suspicion of choledocholithiasis. Eight hours after CPRE the patient presented with hematemesis amd hypotension. With emergency EGD, the AA identified a small bleeding mucosal tear (visible vessel with spurting) just proximal to the esophagogastric junction. The patient was safely treated with endosc…

Nutrition, malnutrition and dietary interventions in inflammatory bowel disease

2014

Inflammatory Bowel Disease (IBD), which includes both Crohn's disease (CD) and Ulcerative Colitis (UC), is a chronic idiopathic inflammatory disorder affecting the gastrointestinal tract. Diet, as a source of luminal antigens, is thought to be an important factor in the pathogenesis of IBD. often the nutritional status of patients is significantly compromised, particularly in CD. several factors, including drug-nutrient interactions, disease location, symptoms, and dietary restriction can lead to protein energy malnutrition and specific nutritional deficiencies. solid evidence regarding the accountability of certain dietary components in the etiology of IBD are lacking. With regard to malnu…

CD40 ligand and MCP-1 as predictors of cardiovascular events in diabetic patients with stroke.

2009

Aim: Up-regulation of soluble CD40 ligand (sCD40L) and of monocyte chemoattractant protein-1 (MCP-1) has been found in diabetes and in patients with acute cerebral ischemia. We asked whether (i) the two molecules are similarly upregulated among non-lacunar and lacunar diabetic strokes and (ii) sCD40L and/or MCP-1 predict the risk of cardiovascular events in this setting.Methods: Ninety patients with type 2 diabetes mellitus presenting with an acute ischemic stroke (compared with 45 control subjects) were evaluated on admission and up to 36 months (median 24 months) after the event.Results: Diabetic patients with acute stroke had higher plasma CD40L and MCP-1 than controls (p<0.0001), wit…

Colorectal cancer in patients with type 2 diabetes mellitus: a single-center experience

2017

Type 2 diabetes mellitus (T2DM) is associated with an increased risk of colorectal cancer (CRC). The aim of the study is to evaluate the prevalence of CRC in a cohort of Caucasian patients with T2DM and the association with other variables previously known to be related with increased risk of CRC. We retrospectively evaluated the data of 741 consecutive Caucasian patients with T2DM who underwent colonoscopic screening in our tertiary referral center. A control cohort of 333 patients with thyroid disease was selected to evaluate the difference in the incidence of CRC. At a median follow-up of 132.5 months (range 33.3-175.7), 67 cases of cancer (prevalence 9%) occurred; among these, 14 cases …

Gastric polypoid lesions. Our experience.

2010

BACKGROUND AND AIM: The Authors report the results of their experience on polypoids lesions of the stomach and on endoscopic polypectomies. PATIENTS AND METHODS: A study on 2000 OGD (oesophagogastroduodenoscopy) has been carried out on 95 patients with polypoid lesions. The authors have analysed the associations existing between histological type and symptomatology and localisation of the lesion and the status of the Helicobacter pylori and the risk of cancerization. The data were confronted with the ones already available. RESULTS: In the majority of the cases, the polypoid lesions were asymptomatic, the localization changed according to the histological type, with the antrum as the most a…

OSSERVAZIONi A PROPOSITO DI UN CASO DI CISTI GIGANTE DELLA MILZA

2005

The Authors, on the basis of a case of giant spleen cyst with positive tumoral markers, analyse some epidemiological and clinical aspects related to splenic non parasitic cysts. They affirm the priority of the conservative surgery, whenever possible, followed by an appropriate follow-up, although in this case their therapeutic choice was radical, due to the lack of residual parenchyma. In accordance with the data of several publications, as well as on the basis of the results obtained, the conservative approaches have been reevaluated, above all in view of the modern findings related to the function of the spleen. The conservative approach cannot be carried out in the following cases: neopl…

Pouchitis: A tridimensional view

2016

The preferred surgical treatment of ulcerative colitis (UC) and familial adenomatous polyposis (FAP) is represented by proctocolectomy with ileal pouch-anal anastomosis (IPAA). However, patients with UYC who have undergone IPAA are prone to develop several complications, which include surgery related/mecchanical complications; inflammatory or infectious disoreders; dysplasia or neoplasia; and systemic or metabolic disorders. Pouchitis, which is defined as the acute and/or chronic inflammation of the ileal reservoir, represent the most common long-term adverese sequela after IPAA. Gut microbiota play a pivotal role in the initiation and disease progression of pouchitis. Pouchitis can be clas…
