The Colonoscopy Satisfaction and Safety Questionnaire (CSSQP) for Colorectal Cancer Screening: A Development and Validation Study.

Colonoscopy services working in colorectal cancer screening programs must perform periodic controls to improve the quality based on patients' experiences. However, there are no validated instruments in this setting that include the two core dimensions for optimal care: satisfaction and safety. The aim of this study was to design and validate a specific questionnaire for patients undergoing screening colonoscopy after a positive fecal occult blood test, the Colonoscopy Satisfaction and Safety Questionnaire based on patients' experience (CSSQP).

Colonic stenting as a bridge to surgery versus emergency surgery for malignant colonic obstruction: results of a multicentre randomised controlled trial (ESCO trial).

Background: The aim of colonic stenting with self-expandable metallic stents in neoplastic colon obstruction is to avoid emergency surgery and thus potentially reduce morbidity, mortality, and need for a stoma. Concern has been raised, however, about the effect of colonic stenting on short-term complications and long-term survival. We compared morbidity rates after colonic stenting as a bridge to surgery (SBTS) versus emergency surgery (ES) in the management of left-sided malignant large-bowel obstruction.

Tumor regression and survival after perioperative MAGIC-style chemotherapy in carcinoma of the stomach and gastroesophageal junction.

Background: We assessed the effectiveness of perioperative MAGIC-style chemotherapy in our series focused on the tumor regression grade and survival rate.

Methods: We conducted a retrospective study of 53 patients following a perioperative regimen of epirubicin, cisplatin, and fluorouracil or capecitabine (ECF/X). Forty-four (83 %) neoplasias were located in the stomach and 9 (17 %) were located at the esophagogastric junction.

Accuracy for optical diagnosis of colorectal polyps in clinical practice.

Background: Optical diagnostic involves predicting polyp histopathology from its endoscopic characteristics. It is only recommended for diminutive polyps ( < or = 5 mm) and for predictions made with high confidence.

Objectives: To evaluate the accuracy of optical imaging in clinical practice and to assess if optical diagnosis is useful for predicting future colonoscopy surveillance intervals without waiting for histopathological analysis.

Relationship between tobacco, cagA and vacA i1 virulence factors and bacterial load in patients infected by Helicobacter pylori.

Background And Aim: Several biological and epidemiological studies support a relationship between smoking and Helicobacter pylori (H. pylori) to increase the risk of pathology. However, there have been few studies on the potential synergistic association between specific cagA and vacA virulence factors and smoking in patients infected by Helicobacter pylori.

Laparoscopic sleeve gastrectomy with endoscopic versus bougie calibration: results of a prospective study.

Introduction: The use of the endoscope for the calibration of the gastric sleeve, instead of the standard use of the bougie, is a safe procedure and gives the surgeon a higher sense of security. The aim of this study was to evaluate the effect of the use of endoscopic guidance on postoperative complications and mid-term results of the bariatric procedure.

Patients And Methods: A prospective, nonrandomized study was performed at the General University Hospital of Elche (Alicante, Spain) between 2010 and 2013.

Direct peroral cholangioscopy using an ultrathin endoscope: making technique easier.

Background: Cholangioscopy is a useful tool for the study and treatment of biliary pathology. Ultrathin upper endoscopes allow direct peroral cholangioscopy (DPC) but have some drawbacks.

Objective: The aim of the study was to evaluate the success rate of DPC with an ultrathin endoscope using a balloon catheter to reach the biliary confluence.

Factors related to the effectiveness of variable stiffness colonoscope: results of a multivariate analysis.

Background: Various studies and two meta-analysis have shown that a variable stiffness colonoscope improves cecal intubation rate. However, there are few studies on how this colonoscope should be used.

Objective: The aim of this study was to identify factors related to the advancement of the colonoscope when the variable stiffness function is activated.

Material And Methods: All patients who attended the outpatient clinic for gastroscopy or colonoscopy examinations were included in the study.

Understanding the mechanisms of paracentesis-induced crculatory dysfunction.

Large-volume paracentesis induces early beneficial haemodynamic changes that may be shortly followed by a disorder known as paracentesis-induced circulatory dysfunction, characterized by a marked activation of the renin-angiotensin axis. Evidence is accumulating however that this disorder is secondary to an accentuation of an already established arteriolar vasodilatation. The causes of this syndrome are probably multiple and may include the dynamics of paracentesis (the rate of ascitic fluid extraction), release of nitric oxide from the vascular endothelium and mechanical modifications due to abdominal decompression.

Intestinal permeability is increased in patients with advanced cirrhosis.

Background/aims: The dysfunction of the intestinal barrier is a factor that has been related to bacterial translocation from lumen to extra-intestinal sites and consequently to the development of spontaneous bacterial peritonitis. The aim of this study was to investigate if the alterations of the intestinal barrier in cirrhosis are related with the degree of liver failure and associated with other clinical complications.

Methodology: Intestinal permeability was assessed by means of the lactulose/mannitol test in 79 cirrhotic and 25 controls subjects.
