title: Partial splenic decapsulation: a simplified operation for splenic pseudocyst.
abstract: Splenic pseudocysts have traditionally required splenectomy because of the risks imposed by partial splenectomy or excision of the cyst lining. During the past 2 years, a 6-year-old boy and a 9-year-old girl presenting with vague upper abdominal discomfort, palpable splenomegaly, and a large unilocular sonolucent cyst within the spleen, were treated by partial splenic decapsulation with preservation of the hilar blood supply. This procedure involves mobilizing the spleen by dividing the renal, colic, and diaphragmatic attachments; decompressing the liquefied cyst contents through a thoracostomy trochar; excising the outer splenic capsule and gaining hemostasis of the splenic wall with a running interlocked silk suture; and providing external tube drainage of the left upper quadrant. During the follow-up period of 26 and 12 months, splenic size has returned to normal. Serial nuclear scan and ultrasound show a small residual crescent-shaped deformity of the functioning splenic remnant. We conclude that partial splenic decapsulation for splenic pseudocyst is simpler and safer than other preservation procedures attempted, and carries no increased risk of recurrence from leaving a portion of the pseudocyst wall.
