Cap-assisted water immersion for minimal sedation colonoscopy: prospective, randomized, single-center trial.

Background And Aim: Water immersion insertion is able to reduce discomfort and need for sedation during colonoscopy. A cap attached to the colonoscope tip may improve insertion during air insufflation colonoscopy. According to several reports, both techniques alone may result in higher detection of neoplastic lesions.

The role of chronic inflammation: chronic pancreatitis as a risk factor of pancreatic cancer.

Pancreatic carcinoma is a condition with late diagnosis and one for which there is no effective screening method. One possible diagnostic approach of so-called early adenocarcinoma is the identification and systematic examination of individuals at risk for this condition. Between 1992 and 2005 we systematically observed 223 individuals diagnosed with chronic pancreatitis.

Combination of water immersion and carbon dioxide insufflation for minimal sedation colonoscopy: a prospective, randomized, single-center trial.

Objective: Water immersion insertion and carbon dioxide (CO2) insufflation, as alternative colonoscopic techniques, are able to reduce patient discomfort during and after the procedure. We assessed whether the combination of water immersion and CO2 insufflation is superior in efficacy and patient comfort to other colonoscopic techniques.

Methods: In a prospective, randomized study, a total of 420 patients were randomized to either water immersion insertion and CO2 insufflation during withdrawal (water/CO2), water insertion and air insufflation during withdrawal (water/air), CO2 insufflation during both insertion and withdrawal (CO2/CO2), or air insufflation during both insertion and withdrawal (air/air).

[Pancreatic cancer--association with diabetes mellitus and smoking].

Introduction: Pancreatic cancer is a disease with rather poor prognosis. This can be explained, among other reasons, by unusually aggressive course of the tumour growth and, in the majority of cases, late, and thus further treatment limiting, diagnosis. In addition, no effective screening programme for pancreatic cancer is available and thus identification of risk factors associated with the development of pancreatic cancer represents a possible approach to diagnosing early stages of the disease.

EuroOOPS: an international, multicentre study to implement nutritional risk screening and evaluate clinical outcome.

Background & Aims: The aim of the study was to implement nutritional risk screening (NRS-2002) and to assess the association between nutritional risk and clinical outcome.

Methods: NRS-2002 was implemented in 26 hospital departments (surgery, internal medicine, oncology, intensive care, gastroenterology and geriatrics) in Austria, the Czech Republic, Egypt, Germany, Hungary, Lebanon, Libya, Poland, Romania, Slovakia, Spain and Switzerland. Being a prospective cohort study, randomly selected adult patients were included at admission and followed during their hospitalisation.
