Splenectomy Indications · Observe/Embolize vs Splenectomy

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Etiology + emergency?
   Trauma or hematologic/splenic disease? Hemodynamically unstable?
   • Splenic rupture (trauma), hemodynamically unstable → Trauma + unstable → emergency splenectomy
   • Trauma, stable → Trauma stable → spleen-preserving ± embolization
   • Hematologic: refractory ITP / severe hereditary spherocytosis / certain hemolytic anemias → Refractory hematologic → laparoscopic splenectomy
   • Splenic tumor/symptomatic cyst/abscess, significant hypersplenism → Splenic mass/hypersplenism → resection
2. [End] Trauma + unstable → emergency splenectomy
   Traumatic splenic rupture + hemodynamic instability → emergency laparotomy splenectomy (or splenorrhaphy/partial resection); rapid resuscitation and transfusion.
3. [End] Trauma stable → spleen-preserving ± embolization
   Trauma, stable → non-operative management (monitoring) ± splenic artery embolization (high-grade injury/contrast extravasation); failure/becoming unstable → surgery; preserve the spleen where possible (especially in children).
4. [End] Refractory hematologic → laparoscopic splenectomy
   Refractory ITP (failed steroids/IVIG/TPO-RA/rituximab), severe hereditary spherocytosis, etc. → elective laparoscopic splenectomy; vaccinate 2 weeks preoperatively (pneumococcal/meningococcal/Hib); partial splenectomy in children to preserve immunity; prevent overwhelming post-splenectomy infection (OPSI).
5. [End] Splenic mass/hypersplenism → resection
   Splenic tumor/symptomatic cyst/abscess, significant hypersplenism → splenectomy (laparoscopic preferred; massive/malignant may be open); likewise preoperative vaccines and OPSI prevention.
