Real‐Time In Vivo Monitoring of Anastomotic Intestinal Ischemia Using Implantable Resorbable Organic Sensors

open access: yesAdvanced Science, EarlyView.
Resorbable impedance sensors are successfully implanted into porcine small intestinal anastomoses. Impedance was recorded for 2 hours prior, and 2 hours following ischemia induction, and a significant drop in tissue impedance was observed. Abstract Anastomotic failure remains one of the most severe complications in gastrointestinal surgery.

High‐Speed, Maneuverable, and Terrain‐Adaptive Micro‐Robot with Tree Frog‐Inspired Bionic Feet

open access: yesAdvanced Science, EarlyView.
A 7.5 mm micro‐robot integrates tree frog‐inspired bionic feet with an electromagnetic linear motor to achieve high‐speed locomotion, slope climbing, and precise turning. It reaches 39 body lengths per second and ascends 30° slopes. The system demonstrates strong potential for inspection tasks in confined and complex environments, such as micro‐aero ...

SERS‐AI‐LUA‐Driven Salivary Diagnosis of Head and Neck Cancer Using Graphene‐Assisted Plasmonic Nanocorals

open access: yesAdvanced Science, EarlyView.
The developed graphene‐assisted plasmonic nanocoral platform enables sensitive, label‐free surface‐enhanced Raman scattering analysis of salivary metabolites for head and neck cancer (HNC) detection. When combined with machine learning classification and nonnegative least squares‐based spectral deconvolution, this approach achieves 98% diagnostic ...

Safety and Efficacy of Pelvic Reinforcement Procedure for Preventing Postoperative Perineal Hernia After Robotic Abdominoperineal Resection: A Single‐Center, Retrospective Cohort Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study aimed to investigate the safety and efficacy of pelvic reinforcement procedure (PRP) in robotic abdominoperineal resection (Ro‐APR). PRP‐ had a significantly higher rate of imaged perineal hernia (PH) (39.2% vs. 6.7%, p = 0.005) and symptomatic PH (19.6% vs.
