Article Synopsis
  • The study evaluates the thermal safety of the BeShape One Device, a noninvasive ultrasound tool for waist reduction, using a swine model to analyze temperature changes and tissue impact.
  • The research involved various applicators and included assessments such as clinical observations, skin reactions, and advanced temperature measurement techniques.
  • Results indicated that the device is safe, with no lasting adverse effects on the skin or surrounding tissues, confirming its potential for effective fat reduction without thermal damage.

Background: New animal models provide insights into the pathogenesis of different types of inflammatory bowel disease as well as novel pathways for new therapeutic options. However, the scarcity of large animal models hinders the research and development of new surgical procedures and technological devices in inflammatory bowel disease surgery. Common small animal inducible models involve chemical agents that result in the development of acute intestinal inflammation.

Background: Performing a full-thickness intestinal wall resection of a sessile polyp located on the mesenteric side with a compression clip may lead to compression of mesenteric vessels. The application of such a clip may therefore cause a compromised blood supply in the particular bowel segment, leading to perforation.

Objective: To evaluate the performance of a newly developed, nitinol compression clip, called the NiTi clamp, for full-thickness resection of the bowel wall, while the clip is deliberately deployed endoluminally on the mesenteric side.

Foreign-body granulomas within intramyocardial arteries were detected in three domestic pigs (Sus scrofa domestica) in a routine transcoronary safety assessment study. The foreign bodies stained light grayish-blue by hematoxylin and eosin (H&E) and were strongly birefringent by polarized light microscopy. By their morphological features, they were identified as cotton fibers.

Background: Generations of investigators have attempted to achieve compression bowel anastomosis by a sutureless device, providing temporary support to the tissue and facilitating the natural healing process. The biocompatibility of nickel-titanium alloy has made it attractive for use in medical implants and devices, and several studies have described the creation of a side-to-side compression anastomosis in colon surgery with a nickel-titanium clip. We evaluated the feasibility and safety of a newly designed gun for applying a nickel-titanium compression anastomosis ring (CAR) to create an end-to-end colorectal anastomosis in a porcine model.
