A33yo woman is undergoing a laparoscopic splenectomy for ITP. She has not responded to corticosteroids. Just prior to surgery, her plt count is 22K. There is persistent oozing from her trocar sites and w/in her abd as the spleen is being isolated from the surrounding structures. Her vital signs are stable.

Sarcoidosis
A 44yo man is seen in the office b/c of abd pain. He has thalassemia major. Vital signs are normal. His spleen is massively enlarged. In addition to decreasing the risk for splenic rupture, what is the most likely benefit of splenectomy for this pt?

Carcinoma
A 70yo man has massive upper GI bleeding while he is in the surgical ICU, where he is being txd for severe pancreatitis w/ necrosis. Arterography shows bleeding form the splenic artery into the pancreatic phlegmon w/ a fistula to the stomach. Splenic artery embolization is performed. If the spleen completely infarcts, which of the following would you expect to see on the peripheral blood smear?
Increased Howell-Jolly bodies
A 18yo man is admitted to SICU following surgery for injuries sustained in a MVC. He underwent splenectomy for Grade 5 splenic rupture and open reduction and internal fixation of compound right tibia and fibula fractures. He has multiple fractured ribs on the left and a pulmonary contusion on the left. He is intubated. Vital signs are stable. What is the optimal timing for administering polyvalent pneumococcal vaccine for this pt?
