Preoperative Indocyanine Green Tattooing for Robotic-Assisted Surgery in Rectal Cancer.
Asian J Endosc Surg
January 2025
Department of Surgery, Chibanishi General Hospital, Chiba, Japan.
Introduction: Preoperative identification of the site of rectal cancer surgery is crucial for ensuring accurate tumor localization and resection. Commonly employed methods include contrast-enhanced enterography and endoscopic marking techniques, such as clipping and India ink tattooing. However, India ink tattooing poses challenges, including obstruction of the surgical field, ink leakage into the abdominal cavity, and potential complications such as peritonitis and adhesive bowel obstruction.

Introduction: In robot-assisted sacrocolpopexy (RSC) for patients with cystocele, accurate identification of the vaginal point Aa from the serosal side is crucial for surgical mesh placement in the appropriate position. We developed a novel Pharus method for exactly locating the point Aa for RSC.
Methods: In the Pharus method, the tip of a rigid endoscope was placed directly on the vaginal point Aa.

Accurate tumor localization is crucial for the success of minimally invasive surgery, as it minimizes the resection of normal tissues surrounding tumors. Traditional methods for marking gastrointestinal (GI) tumors, such as ink tattooing, intraoperative gastroscopy or colonoscopy, and placement of metal clips, have major drawbacks in their application in laparoscopic surgery. Therefore, the development of safe and easy-to-operate marking methods for accurate and real-time detection of GI tumors during laparoscopic surgery remains an ongoing challenge.

Despite substantial progress in the diagnosis of jaundice/hyperbilirubinemia as the most common disease and cause of hospitalization of newborns, on the eve of Industry/Healthcare 5.0, the development of accurate and reliable wearable diagnostic sensors for noninvasive smart monitoring of bilirubin (BIL) is still in high demand. Aiming to fabricate a smart wearable sensor for early diagnosis of neonatal jaundice and its therapeutic monitoring, we here report a fluorescent dermal nanotattoo that further coupled with an IoT-integrated wearable optoelectronic reader for minimally invasive, continuous, and real-time monitoring of BIL in interstitial fluid.

Unlabelled: Transdermal drug delivery has emerged as an alternative to conventional drug delivery systems as it enables painless and convenient drug administration. However, next-generation healthcare systems need to facilitate "on-demand" delivery operations and should be highly efficient to penetrate the physiological barriers in the skin. Here, we report an ultrathin dye-loaded epidermal tattoo (UDET) that allows wirelessly stimulated drug delivery with high efficiency.
