Application of Real-Time Augmented Reality Laparoscopic Navigation in Splenectomy for Massive Splenomegaly

Area of Science:

• Minimally Invasive Surgery
• Surgical Navigation Technologies
• Gastrointestinal Surgery

Background:

• Massive splenomegaly presents surgical challenges in laparoscopic splenectomy.
• Accurate intraoperative guidance is crucial for complex procedures like splenic artery dissection.

Purpose of the Study:

• To assess the clinical impact and technical feasibility of augmented reality laparoscopic navigation (ARLN) in laparoscopic splenectomy for massive splenomegaly.
• To compare surgical outcomes between patients who underwent ARLN-assisted and conventional laparoscopic splenectomy.

Main Methods:

• A comparative study involving 17 patients in the ARLN group and 26 in the Non-ARLN group.
• Propensity score matching (PSM) was used to create comparable groups for analysis.
• Clinical data including intraoperative blood loss, surgical success rates, and postoperative hospital stay were collected.

Main Results:

• The ARLN group demonstrated significantly lower mean intraoperative blood loss (306.6 ml vs. 462.6 ml).
• Successful splenic artery dissection was achieved in all ARLN patients, compared to 12 in the Non-ARLN group.
• Postoperative hospital stay was significantly shorter in the ARLN group (3.8 days vs. 4.5 days).

Conclusions:

• Augmented reality laparoscopic navigation (ARLN) is technically feasible and clinically impactful for laparoscopic splenectomy in massive splenomegaly.
• ARLN provides accurate intraoperative image guidance, enhancing surgical performance and patient outcomes.
• The use of ARLN can lead to reduced complications and improved efficiency in complex laparoscopic surgeries.
