Detectability of Hygroscopic Clips Used in Breast Cancer Surgery.

Sonographically detectable clips were introduced over the last decade. We retrospectively studied the rate and duration of sonographically detectable clip detectability in patients with breast cancer who had sonographically detectable clips inserted over a 2-year period. Nine of 26 patients had neoadjuvant chemotherapy, with all clips remaining detectable 140 to 187 days after insertion.

Ultrasound evaluation of visceral and subcutaneous fat reduction in morbidly obese subjects undergoing laparoscopic gastric banding, sleeve gastrectomy, and Roux-en-Y gastric bypass: a prospective comparison study.

Background: Visceral fat (VF) plays a major role in the development of metabolic syndrome associated with obesity. The aim of our study is to compare VF and subcutaneous fat (SCF) reduction measured by ultrasonography (US) after laparoscopic adjustable gastric banding (LAGB), laparoscopic sleeve gastrectomy (LSG), and laparoscopic Roux-En-Y gastric bypass (LRYGB).

Methods: Thirty-nine morbidly obese patients were prospectively evaluated by US before surgery and 3, 6, and 12 months following surgery to determine VF and SCF thickness.

Ileocolic versus small-bowel intussusception in children: can US enable reliable differentiation?

Purpose: To assess clinical and ultrasonographic (US) criteria that can be used to confidently differentiate ileocolic from small-bowel intussusception.

Materials And Methods: Institutional review board approval was obtained for this retrospective study, and the need to obtain informed consent was waived. US and clinical data for children given a diagnosis of intussusception in the years 2007 through 2011 were evaluated.
