From October 19 to 22, 2024, the American College of Surgeons (ACS) Clinical Congress 2024 was held in MOSCONE CENTER, San Francisco, California. Thousands of global surgeons and researchers in related fields gathered at the congress. Associate research professor Yan Xiaopeng and PhD Zhang Miaomiao from Department of Hepatobiliary Surgery in the First Affiliated Hospital (FAH) of Xi’an Jiaotong University (XJTU) were invited to attend and deliver oral and e-Poster presentations at the meeting.

Associate research professor Yan Xiaopeng gave an oral presentation entitled "Feasibility experiment of a novel deformable self-assembled magnetic anastomosis ring (DSAMAR) for gastrointestinal anastomosis through natural orifice". DSAMAR is a novel type of magnetic anastomosis ring designed and developed by PhD Zhang Miaomiao, led by associate research professor Yan Xiaopeng, for the treatment of digestive tract stenosis via a single port. Revolutionary design concept and unique magnetic characteristics of DSAMAR yielded good operability and high clinical efficacy in clinical trials. The research results related to DSAMAR have been reported at multiple international academic conferences, receiving widespread recognition from by colleagues and peers in the field of magnetic surgery.

PhD Zhang Miaomiao gave an e-Poster presentation entitled “Comparative study of cylindrical and circular ring magnets in colonic anastomosis in rats”, illustrating the Peripheral Decision Theory of gastrointestinal magnetic anastomosis recently proposed by the magnetic surgery team based on the analysis of animal experimental results. This theory, along with Tissue Tension Theory, Magnetic Force Sea-Level Theory and Yan-Zhang's Staging of Digestive Tract MCA, constitutes an important fundamental theory of digestive tract magnetic anastomosis, which is the cornerstone for establishing digestive tract magnetic anastomosis system.
