AIM To investigate the effectiveness of low-volume plus ascorbic acid [polyethylene glycol plus ascorbic acid (PEG + Asc)] and high-volume plus simethicone [polyethylene glycol plus simethicone (PEG + Sim)] bowel preparations. METHODS A total of one hundred and forty-four outpatients (76 males), aged from 20 to 84 years (median age 59.5 years), who(More)
BACKGROUND Video-games have become an integral part of the new multimedia culture. Several studies assessed video-gaming enhancement of spatial attention and eye-hand coordination. Considering the technical difficulty of laparoscopic procedures, legal issues and time limitations, the validation of appropriate training even outside of the operating rooms is(More)
PURPOSE To assess the best technique and the diagnostic accuracy of Quasistatic Ultrasound Elastography (QUE) in thyroid nodules. Interobserver agreement was also evaluated. MATERIALS AND METHODS A preliminary study of 50 patients with 54 thyroid nodules was performed with quantitative software in order to define the best cut-off value of different(More)
Construct validity of virtual laparoscopic simulators for basic laparoscopic skills has been proposed; however, it is not yet clear whether the simulators can identify the actual experience of surgeons in more complex procedures such as laparoscopic Roux-en-Y gastric bypass. This study tested the ability of the Lap Mentor simulator to recognize the(More)
PURPOSE To assess the clinical value of quantitative elastosonography compared with multiparametric ultrasound in differentiating the nature of thyroid nodules. METHODS AND MATERIALS Ninety-seven consecutive patients (32 males, 65 females, mean age, 54 years, range 20-81 years) with thyroid nodules previously detected at color-Doppler ultrasound (CDUS),(More)
Intestinal intussusception is a rare pathology in adults and counts for approximately 5-16% of all invaginations, according to literature. We report the case of a 54 years-old male affected by a double ileo-ileal and ileocecocolic invagination secondary to a submucosal intestinal lipoma. Because of a bowel obstruction symptomathology, the diagnosis was(More)
Internal abdominal hernias are a rare cause of intestinal obstruction (0.2-0.9%). Transmesenteric hernia is a rare type of internal hernia and usually in adult people is acquired. We report the case of a 44 year-old caucasian female with a small bowel occlusion after right nephrectomy for clear cell renal carcinoma caused by an acquired transmesenteric(More)
To assess whether ultrasound elastography (USE) with strain ratio increases diagnostic accuracy of Doppler ultrasound in further characterisation of cytologically Thy3 thyroid nodules. In two different university diagnostic centres, 315 patients with indeterminate cytology (Thy3) in thyroid nodules aspirates were prospectively evaluated with Doppler(More)
This study was done to compare quantitative elastosonography and ultrasound analysis in the characterisation of thyroid nodules. From July 2009 to September 2011, 123 patients with 147 thyroid nodules were included in our study. All patients enrolled had to undergo thyroidectomy because of nodular thyroid disease (goitre or nodules). After preliminary(More)
BACKGROUND The rising interest towards minimally invasive surgery has led to the introduction of laparo-endoscopic single site (LESS) surgery as the natural evolution of conventional multiport laparoscopy. However, this new surgical approach is hampered with peculiar technical difficulties. The SPIDER surgical system has been developed in the attempt to(More)
