Introduction of a simple technique for partial splenectomy in multiple trauma patients

The spleen is the most commonly injured intraperitoneal organ in multiple trauma patients. Total splenectomy results in immunodeficiency and predisposes patients to certain infections.

Performing partial splenectomy with a safe, simple, and definite technique in trauma patients with hemodynamic instability and accompanying intra-abdominal injury could play an important role in the preservation of immune function and reducing morbidity.

From 2006 to 2009, a total of 20 patients underwent partial splenectomy, at Mobasher and Be'sat hospitals. Patients with splenic injuries of up to stage IV and grade 3 shocks underwent partial splenectomy. The operations were performed without vascular isolation and by wedge resection of the injured splenic tissue and repair with chromic 2/0 sutures in two rows. Three months later, patients were evaluated by a Tc99 liver-spleen scan, complete blood count, and blood smear.

There were 16 male and four female patients with an age range of 4 to 54 years old. Ten patients had additional intra and extra abdominal injuries. The salvaged spleen tissue was approximately 30% in nine patients, 40 to 50% in two, and more than 50% in another nine patients. The operation time was less than three hours and hospital stay was 3 to 15 days for 90% of the patients. No complications occurred after the surgery or during the follow up. For all patients, the complete blood count, peripheral smear, and liver-spleen scan were normal after six months.

Partial splenectomy with preserving at least 30% of the splenic tissue can be performed for trauma patients using wedge resection of the injured splenic tissue and repair by chromic 2/0 sutures in two rows. Using this technique, there is no need for vascular isolation or hemostatic materials. Splenic function is presented and associated intra and extra abdominal injuries are not contraindications for partial splenectomy.
