Surgeon-performed ultrasound for the staging of acute diverticulitis: Preliminary results of a prospective study.

Introduction: Although contrast-enhanced abdominal computed tomography (CEACT) is still considered the criterion standard for the assessment of suspected acute diverticulitis, in recent years, the use of point-of-care ultrasound (POCUS) has been spreading more and more in this setting. The aim of this study was to compare CEACT to POCUS for the diagnosis and staging of suspected acute diverticulitis.

Methods: This is a prospective study conducted on 55 patients admitted to the emergency department of two Italian Hospitals with a clinical suspicion of acute diverticulitis between January 2014 and December 2017.

[Postoperative radiologic follow-up of rectocolonic anastomoses. The visualization of fistulous passages after evacuation].

The early postoperative study of colo-rectal anastomoses is a common diagnostic procedure with symptomatic patients which is extended to asymptomatic patients by some authors. Eighty-eight anastomotic fistulas were early diagnosed after intervention in 316 patients who underwent a water-soluble contrast enema. Four out of these fistulas (4.

[Gastrointestinal interventional radiology. Technics and preliminary results].

Gastrointestinal interventional radiology allows the positioning of feeding tubes in difficult situations, as well as the balloon dilatation of stenoses and the transintestinal drainage of fistulas and collections, with some advantages over endoscopic and surgical procedures. In the present series feeding tubes were positioned in 26 patients, both to get over the strictures in the upper gastrointestinal tract and to exclude fistulous tracts or anastomotic leaks from alimentary transit. Balloon dilatation was performed in 10 patients with stenoses of different aetiologies, at different levels of the gastrointestinal tract: in all cases the clinical symptoms diminished.

[Structuring and use in clinical research of a software for the diagnosis and features of polypoid lesions of the colorectum].

Double contrast enema and endoscopy are very important in the diagnosis of adenomas and early cancer of the colon and rectum. These exams can not only detect the presence, but also suggest the histologic diagnosis, of polypoid lesions of the colon. An Olivetti M24 Personal Computer was used to create a software to study the results obtained by double contrast enema, and to compare them with endoscopy and pathology.

[Proposal for a radiological classification of multiple adenomatosis of the colon].

The double contrast enemas of 47 patients with multiple adenomatosis of the colon and rectum were analyzed. According to the density and the distribution of polyps on the mucosal surface, the radiological patterns were classified into three different groups: sporadic, dense and confluent adenomas. Radiographic patterns of each patient were related to the clinical and pathological data collected during the diagnosis and the follow-up.
