Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

This study explores automatic analysis of Minimally Invasive Surgery (MIS) videos for better surgical training and patient safety. Techniques like 3D reconstruction and tool tracking from laparoscopic images show promising results for surgical navigation.

Area of Science:

  • Medical image analysis
  • Computer-assisted surgery
  • Minimally Invasive Surgery (MIS)

Background:

  • Minimally Invasive Surgery (MIS) video analysis offers a non-intrusive method for improving surgical training and patient safety.
  • Existing surgical training and evaluation systems lack objectivity and reproducibility.

Purpose of the Study:

  • To present methods and techniques for automatic analysis of Minimally Invasive Surgery (MIS) videos.
  • To demonstrate the potential of surgical video analysis for 3D reconstruction and tool/organ tracking.

Main Methods:

  • 3D reconstruction of the surgical field from laparoscopic video images.
  • Segmentation and tracking of surgical tools and organs using video analysis.
  • Calculation of 3D tool position and orientation from 2D images.

Application of Laparoscopic Ultrasonography in Primary Choledochal Suture during Combined Two-lens Surgery

Published on: March 28, 2025

  • Translation of preoperative plans into surgical procedures using image shading.

    • Main Results:

    • Demonstrated the ability to calculate the 3D position and orientation of a surgical tool from its 2D laparoscopic image.
    • Showcased the translation of a preoperative resection plan into a hepatectomy procedure using image shading information.
    • Illustrated the potential of surgical video analysis for enhanced surgical navigation and planning.

    Conclusions:

    • Automatic analysis of Minimally Invasive Surgery (MIS) videos holds significant potential for advancing surgical training, evaluation, and navigation.
    • Further research is needed to fully leverage the information within surgical videos for improved patient outcomes.
    • Developed techniques show promise in creating objective evaluation systems and enhancing surgeon assistance.
