Intestinal ultrasonography in adults with Crohn's disease: a 2020 update.

In the last years intestinal ultrasonography (IUS) has increased its role in the management of inflammatory bowel diseases (IBD), that include Crohn's disease (CD) and ulcerative colitis. This is due to the fact that IUS is a non-invasive, inexpensive, and well-tolerated examination technique. Furthermore, it allows a real-time diagnosis with no radiation exposure.

Power Doppler sonography to predict the risk of surgical recurrence of Crohn's disease.

Purpose: The aim of this work is to investigate the role of power Doppler sonography as an additional predictor of surgical recurrence in Crohn's disease.

Methods: A sample of 33 patients, with ileal or ileocolonic Crohn's disease, that had underwent intestinal resection, were retrospectively enrolled. All patients had bowel ultrasonography 7-16 months after resection.

Role of bowel ultrasound as a predictor of surgical recurrence of Crohn's disease.

Background: In Crohn's disease natural history, about 80% of the patients require surgery, which is not curative: unfortunately, the disease recurs in many patients.

Objective: To investigate the role of intestinal ultrasound to predict the risk of post-operative surgical recurrence in Crohn's disease.

Material And Methods: A total of 196 patients, with ileal or ileocolonic Crohn's disease, undergoing intestinal resection, were retrospectively enrolled.

US evaluation of patients affected by IBD: how to do it, methods and findings.

Intestinal US has to be performed very accurately, to obtain an exploration of both small bowel and cholical loops that will be the most complete that is possible; so, this technique requires adequately trained operators. Convex and linear probes with frequency between 3.5 and 7.

[The usefulness of computer tomography in planning cochlear implant surgery].

In recent years, technical progress has created new complex acoustic implants which send an electrical stimulus to the eighth cranial nerve through one or more electrodes inserted through the round window into the scala tympani of the cochlea. The abnormal--mostly osteosclerotic--processes which cause deep hearing loss may prevent electrode insertion. Therefore, internal ear anatomy must be detailed, which is essential to assess the feasibility of surgery and, if surgery is indicated, to plan it properly.

[Therapy of malignant hepatic tumors using percutaneous hot saline injections. Feasibility study and preliminary results].

Purpose: To investigate the feasibility and the results of percutaneous hot saline injection therapy (PSIT) of liver tumors.

Material And Methods: Eight patients with hepatocellular carcinoma (11 nodules), 1 with cholangiocarcinoma and 1 with a metastasis from colon cancer underwent PSIT. The patients were selected according to variable criteria; thus, each patient was considered apart.

[The diagnostic reliability of percutaneous biopsy specimens obtained under instrumental guidance using 4 different types of needles].

To assess if the effectiveness of biopsy sampling, whose usefulness is widely recognized, can be influenced by different cutting mechanisms, we compared four different types of needles (A, B, C, D) in 76 patients, each needle being of the same length (15 cm) and calibre (18 G) but with different tip shapes. Forty biopsy samples were obtained with each type of needle for a total of 160 samples in 76 patients; 61 samples were acquired under CT guidance and 99 under US guidance. The results were subdivided in 6 categories based on biopsy result: PI (diagnosis histotype in malignant lesions), PN (diagnosis of malignancy in neoplastic lesions), P (correct diagnosis in benign lesions), S (suspicion of neoplastic lesion), E (misdiagnosis), NI (insufficient material).

[Pheochromocytoma in childhood. Report of a case of a familial type in an 8-year-old boy].

A case of right adrenal pheochromocytoma in an 8-yr-old boy and its successful surgical management are described. Clinical and statistical data are given for this form and its symptomatology and aetiopathogenesis are illustrated. Particular stress is laid on the occasionally misunderstood importance of the part played by continuous hypertension.
