Laparoscopic splenectomy is a reliable procedure, especially for smaller spleens. Experienced surgeons can simplify this operation using anterior or lateral approaches and splenic artery embolization for larger spleens.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Techniques
  • Gastrointestinal Surgery

Background:

  • Laparoscopic splenectomy initially reported as challenging with a steep learning curve.
  • Limited scope suggested for laparoscopic approach in early stages.

Purpose of the Study:

  • To review and present simplified approaches for laparoscopic splenectomy.
  • To evaluate the feasibility and outcomes of different surgical strategies.

Main Methods:

  • Descriptive study of a prospective database from a tertiary care teaching hospital.
  • Analysis of 51 consecutive laparoscopic splenectomy cases over 4 years.
  • Utilized anterior and lateral surgical approaches, with selective preoperative splenic artery embolization.

Main Results:

  • Low morbidity (11%), mortality (2%), and conversion rates.
  • High recovery rate of accessory spleens (24%).
  • Improved outcomes over time including reduced operating time (3 hours), shorter hospital stay (3 days), and less blood loss.

Conclusions:

  • Laparoscopic splenectomy is reliable for spleens <20 cm; lateral approach simplifies this.
  • Preoperative embolization advised for spleens 20-30 cm; requires experienced surgeon.
  • Laparoscopic splenectomy not recommended for spleens >30 cm; anterior approach reserved for large spleens/partial procedures with embolization.
