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. Similarly, clipping requires palpation, making minimally invasive procedures, such as laparoscopic or robotic-assisted surgery, impractical.

Materials And Surgical Technique: The indocyanine green fluorescence method is employed intraoperatively to monitor blood and lymph flow in the intestinal tract. Here, we discuss the effectiveness of preoperative indocyanine green marking in accurately locating tumors during robot-assisted rectal colorectal surgery.

Discussion: By using the fluorescence properties of indocyanine green, surgeons can precisely identify the tumor site, overcoming the limitations of traditional methods. This technique improves surgical accuracy while minimizing intraoperative risks and achieving optimal oncological outcomes. Preoperative indocyanine green tattooing represents a valuable enhancement to current techniques in rectal cancer surgery, particularly for robot-assisted approaches. Our findings underscore the applicability of preoperative indocyanine green tattooing as a promising alternative in robot-assisted surgery for patients with rectal cancer.

Identification of lesion demarcation during thoracoscopic anatomical lesion resection is fundamental for treating children with congenital lung malformation. Existing lesion demarcations do not always meet the needs of clinical practice. This study aimed to explore the safety and efficacy of near-infrared fluorescence imaging with nebulized inhalation of indocyanine green for thoracoscopic anatomical lesion resection in children with congenital lung malformation.

Purpose: To validate the Axillary Reverse Mapping (ARM) technique with indocyanine green (ICG), focusing on the detection rate and the procedure's feasibility. The predictive factors for metastatic involvement of ARM nodes are also analyzed to define the target population for ARM indication.

Methods: This prospective, observational, non-randomized study of patients with breast cancer included patients with an indication for axillary lymph node dissection (ALND) performed between June 2021 and June 2023.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.
