Gastrointestinal stromal tumors
No full textThe gastrointestinal stromal tumor is one of the most common types of primary non-epithelial intestinal neoplasms. This kind of tumor arises from mesenchymal cells located in organ walls. It exhibits a very large range of differentiation pathways. Clinically, gastrointestinal stromal tumors are usually asymptomatic and can be the cause of surgical emergencies involving bleeding, intussusception or perforation

Virtual endoscopy: already a feasible proposition or a future prospect in diagnostic? A review of the literature
No full textThe aim of this article was to carry out a retrospective analysis of the feasibility of using virtual endoscopy in the field of gastrointestinal diseases. After a retrospective review of the international literature the authors analyse the most controversial aspects of virtual endoscopy such as its effective diagnostic reliability and potential clinical employment with specific reference to diagnosing colon diseases. The international literature shows that virtual endoscopy is currently poorly sensitivity in detecting lesions measuring less than 10 mm in diameter and that the radiologist's experience can negatively condition the trustworthiness of this procedure. Virtual endoscopy is likely to be the future gold standard in the field of diagnostic imaging. Furthermore, it eliminates all the compliance-related problems and any risk of iatrogenic lesions such as perforations and bleedings which are typical of traditional endoscopy. Its current sensitivity, however, is poor and it is unable to detect lesions smaller than 10 mm. Its reliability therefore needs to be improved
Ambulatory surgery: preoperative assessment
No full textOver the past 20 years public health expenditure has progressively increased for various reasons. With the aim of reducing public health expenditure and hospital stays, alternative models of public health care have been more widely adopted over the past two decades: Day Hospital, day surgery and ambulatory surgery. What is meant by ambulatory surgery is the clinical, organisational and administrative possibility of performing surgical operations and/or invasive and semi-invasive diagnostic procedures without hospitalisation of patients, in doctors' surgeries, outpatient departments or protected outpatient facilities. For both the patients and the centres providing the service to be able to exploit all the advantages stemming from this kind of health care provision, careful patient selection is mandatory, including assessment of the impact of any potential concomitant pathologies. Starting from their own personal experience and existing reports in the international literature, the authors analyse the impact that concomitant pathologies may have on patient selection for ambulatory surgery. The authors conclude that thorough preoperative evaluation of all the possible variables involved is the only way of ensuring the success of ambulatory surgery
