Background
Recognition of the importance of the spleen in immunological function and the potential threat of severe postsplenectomy complications have led to the development of parenchyma-preserving surgical procedures. The aim of the present study was to assess the impact of open splenic partial resection on the management of splenic cysts.
Patients and methods
From April 2003 to June 2007, 11 patients with splenic cysts were evaluated. All patients fulfilled the criteria for surgical resection. Ten of the patients (6 women and 4 men) 15–42 years of age (mean: 26.4 years) were subjected to open partial splenectomy. In one patient, a centrally located splenic cyst was considered unsuitable for partial splenectomy, and the patient therefore underwent total spleen excision. Patients with splenic cysts constituted 3.8% of all 290 patients subjected to splenectomy during the study period. Spleen parenchyma was cut with the aid of a LigaSure instrument. Bleeding from the transected splenic parenchyma was secured with argon plasma coagulation and absorbable tape sutures or oxidized cellulose.
Results
Nine of the ten patients underwent successful partial splenectomy. In one patient, insufficient arterial supply to the preserved splenic remnant after excision of the upper cyst-containing splenic pole led to total splenectomy. The mean operative time was 98 min (range: 85–160 min), and mean blood loss was 106 ml (55–200 ml). The mean cyst diameter was 9.1 cm (range: 7–17 cm) and weight was 738 g (range: 230–2,420 g). The postoperative course was uneventful in all cases. Pathological examination showed an epithelial cyst in 8 patients and a pseudocyst in 2. After a mean follow-up of 26.4 months, the size of the splenic remnant constituted, on average, 71% of preoperative spleen size. Moreover, normal splenic vein flow was observed. Platelet counts remained within the normal range, and no cyst recurrence was observed. There were no infections documented during the follow-up period.
Conclusions
Open partial splenectomy is a safe and effective method in the management of nonparasitic splenic cysts. It ensures complete cyst removal, lack of cyst recurrence, and preservation of the spleen functions.
