Robotic Laser Tissue Soldering for Atraumatic Soft Tissue Fusion Guided by Fluorescent Nanothermometry.

Minimally invasive surgical techniques, including endoscopic and robotic procedures, continue to revolutionize patient care, for their ability to minimize surgical trauma, thus promoting faster recovery and reduced hospital stays. Yet, the suturing of soft tissues ensuring damage-free tissue bonding during these procedures remains challenging due to missing haptics and the fulcrum effect. Laser tissue soldering has potential in overcoming these issues, offering atraumatic seamless tissue fusion.

Nanothermometry-Enabled Intelligent Laser Tissue Soldering.

While often life-saving, surgical resectioning of diseased tissues puts patients at risk for post-operative complications. Sutures and staples are well-accepted and routinely used to reconnect tissues, however, their mechanical mismatch with biological soft tissue and invasiveness contribute to wound healing complications, infections, and post-operative fluid leakage. In principle, laser tissue soldering offers an attractive, minimally-invasive alternative for seamless soft tissue fusion.

Preparation of a pig experimental model of defective colon anastomosis - review.

Anastomotic leak is a serious complication in colorectal surgery. The problem of intestinal anastomosis healing disorders is dealt with by a number of experimental studies, especially in applied research. The design of animal models is diverse and the results of individual studies are difficult to compare.

Histological mapping of healing of the small and large intestine - A quantitative study in a porcine model.

Background: Gastrointestinal anastomoses are performed in many patients every year. The pathogenesis of aberrant anastomotic healing and the causes of intestinal leakage are not fully understood. The present study gathered and critically evaluated histological quantitative data to deepen current knowledge of anastomotic healing in the small and large intestine and its complications and outline the options for further experimental in vivo research in large porcine animal models.

Permanent intravenous access in experimental surgery – our experience.

Introduction: Permanent intravenous access is usually required in pigs used for surgical experiments, not only to enable repeated blood sample collections. The aim of this study was to evaluate the patency and complications of vascular access ports (VAP) implanted in pigs included in different surgical experiments. Methods: VAPs were implanted via the external jugular vein in a total of 211 pigs from 7 different experiments.
