The primary immunologic function of the spleen is to clear pathogens and antigens. However, there has been a presumed lack of essential function of the spleen that has led to the spleen being removed completely when indicated. The risk of lifetime post-splenectomy overwhelming sepsis is around 4.25%, with a mortality approaching 60%.


The indications for partial splenectomy include diagnostic partial splenectomy for idiopathic splenomegaly, splenic cysts, benign tumors, metastases, splenic infarct, iatrogenic injury to the spleen, and the hematologic disorder hereditary spherocytosis. Hereditary spherocytosis, an autosomal dominant inherited hemolytic disorder may be particularly relevant with children who are less than 4 years old, who may be at risk for overwhelming postsplenectomy infection (OPSI), but for whom partial splenectomy may reduce hemolytic complications such as anemia, gallstones, and exercise intolerance while preserving splenic function. Children may also be at additional risk of pulmonary hypertension after splenectomy and fulminant sepsis from cat or dog bites. This may not be the case with other hemoglobinopathies for which splenectomy is a treatment.


Animal studies have shown that 25% splenic preservation may be adequate to preserve splenic function. Splenic regrowth does not necessarily occur; but when it does, completion splenectomy may be indicated. Open partial splenectomy and splenic embolization have been described. However, laparoscopic splenectomy may hold advantages over an open approach for the decrease in postoperative pain and recovery time. Splenic embolization has been hampered by complications of splenic abscess, pain, nausea, and fever.

Operative techniques described include ligating the main splenic vessels and the short gastric vessels, but preserving the pedicle arising from the left gastroepiploic vessels. Alternatively the main splenic vessles can be ligated and the short gastric vessels preserved. In both cases, about 10-30% of splenic parenchyma are preserved and a rim of devascularized tissue is left behind to reduce splenic bleeding.
