AI Article Synopsis

  • Accurate localization of tumors is crucial for successful gastric cancer surgery, and the study evaluated the effectiveness of near-infrared fluorescent clips for this purpose.
  • In a clinical trial with 20 patients undergoing laparoscopic gastrectomy, fluorescent clips were placed near tumors and detected during surgery using specialized equipment.
  • Results showed a 75% detection rate for the clips with no related complications, demonstrating the method's safety and feasibility in surgical practice.

Article Abstract

Introduction: Accurate tumor localization and resection margin acquisition are essential in gastric cancer surgery. Preoperative placement of marking clips in laparoscopic gastrectomy as well as intraoperative gastroscopy can be used for gastric cancer surgery. However, these procedures are not available at all institutions. We conducted a prospective clinical trial to investigate the diagnostic performance of near-infrared fluorescent clips (ZEOCLIP FS) in laparoscopic gastrectomy.

Materials And Methods: Patients with gastric cancer or neuroendocrine tumor in whom laparoscopic distal, pylorus-preserving, or proximal gastrectomy was planned were enrolled (n = 20) in this study. Fluorescent clips were placed proximal and/or distal to the tumor via gastroscopy on the day before surgery. During surgery, the clips were detected using a fluorescent laparoscope, and suturing was performed where fluorescence was detected. The clip locations were then confirmed via gastroscopy, and the stomach was transected. The primary endpoint was the detection rate of the marking clips using fluorescence, and the secondary endpoints were complications and distance between the clips and stitches.

Results: Among the 20 patients enrolled, distal and pylorus-preserving gastrectomies were performed in 18 and 2 patients, respectively. All clips were detected in 15 patients, indicating a detection rate of 75.0% (90% confidence interval: 54.4%-89.6%). Furthermore, no complications related to the clips were observed. The median distance between the clips and stitches was 5 (range, 0-10) mm.

Conclusions: We report the feasibility and safety of preoperative placement and intraoperative detection of near-infrared fluorescent marking clips in laparoscopic gastrectomy.

The nanosecond pulsed fibre laser (NsPFL) treatment is extensively employed to distinguish hospital surgical instruments (micro-surgical forceps, surgical blades, orthopaedic drills, and high-precision laparoscopic tools), which are generally composed of stainless steel. Nevertheless, if the laser parameters are not properly optimised, this process may unintentionally provoke corrosion. Maintaining the structural integrity of these materials is essential for ensuring patient safety and minimising long-term costs.

This study aimed to evaluate the diagnostic accuracy of ultrasonography in assessing the response of clipped axillary lymph nodes to neoadjuvant chemotherapy. Between February 2022 and September 2023, 43 patients who underwent axillary lymph node marking for targeted axillary dissection were retrospectively analyzed. Ultrasonography parameters such as the number, size, shape, cortical thickness, hilum status, and treatment response of the clipped lymph node were assessed.

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.

Article Synopsis
  • Identifying the tumor bed (TB) after surgical removal of a tumor is essential for effective radiotherapy planning, but segmenting it from surrounding tissues using CT images poses significant challenges.
  • A new deep learning model enhances the delineation of TB by using prior tumor location information from both pre-operative and post-operative CT scans, improving accuracy in identifying treatment volumes.
  • The model demonstrated a significant improvement in segmenting TB, achieving a higher dice similarity coefficient compared to traditional methods and models without prior information, indicating better performance in clinical applications.
