Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Diagnostic Imaging

Background:

  • Laparoscopic surgery offers advantages but the retroperitoneal approach is limited by restricted working space.
  • Developing solutions to overcome space limitations is crucial for expanding laparoscopic retroperitoneal procedures.

Purpose of the Study:

  • To evaluate the utility of a dilatator balloon for creating working space in laparoscopic retroperitoneal surgery.
  • To assess the role of peroperative ultrasound in guiding balloon placement and monitoring the procedure.

Main Methods:

  • A dilatator balloon was used to create space within the retroperitoneal cavity via a cutaneous access.
  • A blunt dissection technique was employed to create a path for the balloon.
  • Peroperative ultrasound was utilized for real-time guidance and monitoring during balloon insertion and positioning.

Main Results:

  • The dilatator balloon effectively created adequate maneuvering space in the retroperitoneal cavity.
  • Peroperative ultrasound accurately identified anatomical landmarks, such as the inferior renal pole.
  • Ultrasound monitoring facilitated precise control of the balloon catheter's apex and real-time visualization of retroperitoneal organ movement.

Conclusions:

  • The use of a dilatator balloon is a valuable solution for overcoming space limitations in laparoscopic retroperitoneal surgery.
  • Peroperative ultrasound significantly enhances the safety and efficacy of this technique by providing real-time guidance and control.
