The records of eleven patients who underwent splenectomy for Gaucher's disease at The Mount Sinai Hospital from 1967 to 1981 have been reviewed. The major indications for operation were hypersplenism, pain, and mechanical problems associated with a massively enlarged spleen. There were no operative mortalities and the hematologic picture returned to normal in all cases. Because of the danger of overwhelming sepsis following splenectomy, partial splenectomy should be considered as a therapeutic modality in these patients.

Transcatheter embolization of the spleen is gaining popularity as a non-surgical method of treatment for hypersplenism. While early reports documented frequent serious complications, a more recent study noted good results using a fractionated approach with only partial embolization of the periphery of the spleen. This technique was recently used on three patients with hypersplenism associated with severe liver disease. All had grave complications, including sepsis, pneumonia, abscess formation, and progressive liver failure, and all died within six weeks of the angiographic procedure in spite of good haematological responses. Since it is frequently this category of patient in whom the procedure is attempted, definitive surgical splenectomy is suggested following the embolization as soon as the clotting parameters return to normal.

In patients with end-stage liver disease complicated with hypersplenism, neutropenia and thrombocytopenia are risk factors for systemic sepsis and spontaneous bleeding. Granulocyte-macrophage colony-stimulating factor is a naturally occurring cytokine that promotes proliferation and differentiation of granulocyte and monocyte progeny cells. In addition, it is reported to promote the proliferation of megakaryocytes. Its use as an intravenous infusion is Federal Drug Authority (USA) approved for the enhancement of myeloid recovery following autologous bone-marrow transplantation. The present study was initiated to determine whether granulocyte-macrophage colony-stimulating factor could be used to increase the white blood cell and platelet count in patients with cirrhosis and hypersplenism and to determine whether the more convenient subcutaneous route can be used with the same efficacy as the recommended intravenous route. Nine patients with cirrhosis and hypersplenism manifested by a reduced absolute neutrophil count (mean value of 1300 +/- 200/mm3) were studied. In eight patients, Indium white blood cell splenic sequestration scans were obtained before and after the administration of granulocyte-macrophage colony-stimulating factor intravenous infusion or subcutaneously for 7 days. One patient had to discontinue the therapy due to a reaction to granulocyte-macrophage colony-stimulating factor. Following intravenous infusion of granulocyte-macrophage colony-stimulating factor, the mean absolute neutrophil count increased to 2600 +/- 1100/mm3. Following subcutaneous administration, the mean absolute neutrophil count increased to 4100 +/- 200/mm3. No significant change in platelet count occurred with either route of administration. Indium scans obtained before and after the treatment period revealed no significant difference in the splenic uptake.(ABSTRACT TRUNCATED AT 250 WORDS)

We assessed the long-term efficacy of transjugular intrahepatic portasystemic stent-shunt (TIPSS) in 64 patients. Insertion was successful in 56 patients (87.5%). The reasons for its use were: variceal bleeding (49); ascites (6); portal hypertensive gastropathy (6); hypersplenism (2); and embolization of a spontaneous shunt (1). Fourteen patients were Childs A, 20 Childs B and 28 Childs C cirrhotics. Two patients were non-cirrhotic; one with amyloidosis and one with non-cirrhotic portal fibrosis. Patients were followed clinically and radiologically (Doppler ultrasonography and routine portography at 6 months). During 33 patient-years of follow-up, 22 died, 12 during index admission (two were procedure-related) and nine were transplanted. Twenty-five patients are alive, with a mean survival of 7.1 (SD 7) months. Variceal rebleeding occurred in 10 patients (22.7%), one of whom died, and was always associated with shunt insufficiency (shunt thrombosis 2, hepatic vein stenosis (HVS) 1, intimal hyperplasia (IH) 4, dislocated stent 1, inadequate stent 2). Clinical encephalopathy was induced in seven patients (17.1%) following TIPSS. All responded to medical therapy, but two required reduction in shunt size. Ascites improved after TIPSS in 36 patients (87.8%), but reaccumulated in seven (17.5%), associated with shunt dysfunction in five (SBP 2, IH 3, HVS 2). Fatal sepsis occurred in two patients, and 14 other episodes of infection required antibiotics. TIPSS is a useful treatment for variceal bleeding, resistant ascites and portal hypertensive gastropathy. Shunt dysfunction and sepsis occur frequently, and regular surveillance is necessary.

Hypersplenism is defined as the association of anemia, leukopenia, or thrombocytopenia with bone marrow hyperplasia and splenomegaly. Hypersplenism is common in liver cirrhosis and frequent in patients with portal hypertension. The effects of portacaval shunt are variable; hypersplenism hardly ever improves but rarely develops after surgery. Since the spleen is a major component of the mononuclear phagocyte system, splenectomy reduces antibody synthesis. Although splenectomy abolishes hypersplenism, it may lead to sepsis. Recently, partial splenic embolization, using gelform injected directly into the splenic artery, has been performed in patients with cirrhosis. Partial splenic embolization induces an increase in the number of circulating blood cells. In addition, the levels of albumin, hepaplastintest, cholesterol and cholinesterase are increased significantly after treatment. Partial splenic embolization rarely causes problems and may actually be beneficial.

Liver transplantation is one of the most extensive operations in visceral surgery. Preexisting cardiopulmonary abnormalities, disturbances of glucose, hormone, and electrolyte metabolism and cirrhosis-associated diseases, including hypersplenism with thrombopenia and severe coagulopathy, require advanced surgical skills. Optimal perioperative intensive care management is necessary because of the patient's immunosuppressed condition. In principle, patient management after liver transplantation is similar to that performed after major visceral surgery. However, special attention should be paid to initial liver perfusion and function. Like for sepsis in visceral surgery, in liver transplantation monitoring of cytokines and other mediators is important. New approaches for bioartificial liver support in patients with acute liver failure have primarily been developed as a bridging system to liver transplantation, but they may also be of value for patients with septic liver failure or liver failure after major liver resections.

Since the beginning of the decade we can remark an increasing of publications about laparoscopic approach in splenic surgery. We report about 17 unselected own cases (8 males, 9 females). Main indications were 12 hematologic diseases: 9 idiopathic thrombopenic purpuras, 1 hemolytic anemia, 1 Hodgkin's disease and 1 recurrent splenic infarction with hypersplenism and extramedulary hemapoiesis, further 1 unclear sepsis with focal lesions and splenomegaly, 1 dysontogenetic splenic cyst, 1 splenic co-affection of Wegener's disease, and 2 traumatic lesions. We performed in 13 cases asplenectomy, under these 1 time combined with a laparoscopic hernioplasty and 1 time with a complete staging, further in 1 case a partial splenic resection, in 1 case a diagnostic excision and in 2 cases a hemostyptic management without splenectomy. We had to convert in no case, the lethality rate was also 0. As a complication we noted one postoperative bleeding, we could managing also laparoscopically. Our mean operating time of 137 min was evident shorter than the published ones by other authors. Because of our good results and the excellent tolerance by patients we can recommend this proceeding. Nevertheless, it should be limited for surgeons with a large experience at laparoscopic centers.

Absence of the spleen or splenic function predisposes individuals to risk of overwhelming infection. These infections are most often due to encapsulated organisms, especially pneumococcus, Haemophilus influenzae type b, and meningococcus, but any bacterial agent may cause the rapid onset of septicemia, meningitis, pneumonia, and shock characteristic of the asplenic-hyposplenic condition. The risk is greatest in infants and young children, but asplenic-hyposplenic adults also have an increased risk of infection. Prophylactic antibiotics and immunization with polyvalent pneumococcal, H. influenzae type b, and meningococcal vaccines have reduced the incidence of infections in asplenic-hyposplenic individuals, but even these measures have not eliminated the risk. Surgeons have adopted techniques to save as much splenic tissue as possible and some splenic functions, such as pitting red cells, have been preserved, but conservative surgery has not provided total protection against overwhelming infection. Therapies designed to interrupt the cascade of overwhelming sepsis have not yet been successful. In those cases in which the spleen is surgically removed, the underlying disease or condition leading to splenectomy influences the risk of sepsis. Splenectomy incidental to other operations, such as gastrectomy, results in the lowest risk for overwhelming infection, but this is still some 35-fold greater than the risk for overwhelming infections in the general population. In increasing order of risk, the other main indications for surgical removal of the spleen are idiopathic thrombocytopenia purpura, trauma, transplantation procedures, hereditary spherocytosis, staging Hodgkin's disease, portal hypertension with hypersplenism, and thalassemia. Pathologists should comment on the risk of overwhelming sepsis when spleens are processed as surgical specimens, and should carefully weigh all splenic tissue, including accessory spleens and splenic implants (splenosis), in autopsy cases with and without overwhelming sepsis.

Liver injury is associated with parenteral nutrition therapy. Severity of injury varies from minimal and transient increases in liver-related blood tests to biliary cirrhosis and liver failure. Severe parenteral nutrition-related liver disease is usually confined to patients who have undergone massive intestinal resection. In these patients, early sepsis appears to cause initial liver injury, and recurring sepsis and inflammation, local or systemic, may result in its perpetuation and progression. Liver disease associated with parenteral nutrition is not necessarily related either to duration of parenteral nutrition or to delayed intestinal feeding. However, treatment includes enteral nutrition to promote enterohepatic circulation of bile acids and management of inflammation and sepsis, including control of intestinal bacterial overgrowth. Restriction of intravenous lipid emulsions may be important. The clinical picture of advanced liver failure related to short bowel syndrome differs from liver failure with an anatomically normal gastrointestinal tract. In the former, hyperbilirubinemia, hepatosplenomegaly, and functional hypersplenism dominate the clinical picture, and severe ascites and esophageal variceal hemorrhage are unusual. Early referral of these patients for intestinal and/or liver transplantation may provide the best chance for long-term survival.

Partial splenic embolization (PSE) has been demonstrated to be an effective alternative to splenectomy for patients with hypersplenism. Splenectomy in these patients can be associated with an increased risk of perioperative complications, overwhelming post-splenectomy sepsis (OPSS) and mortality. Partial splenic embolization has the advantages of non- operative intervention and resolution of the complications of hypersplenism. We report the use of this technique in patients with portal hypertension and hypersplenism awaiting liver transplant and patients that have undergone othotopic liver transplantation (OLTx) with persistent hypersplenism post-transplant. Six patients--three awaiting liver transplantation and three patients with persistent hypersplenism status post-OLTx--were treated during the period of 1993-99 at the LSUHSC/Willis Knighton Regional Transplant Center in Shreveport, Louisiana. Three patients were male and three female. All six patients had concomitant thrombocytopenia and neutropenia with platelet counts below 50,000. Patients underwent selective arterial catheterization and embolization via a percutaneous approach with Cook microcoils or PVA particles. The lower pole of the spleen was selectively embolized in all patients to achieve a 30-50% reduction in flow as determined by angiography. Patients were followed with routine computed tomography (CT) scans, platelet and WBC counts for a mean of 26 months in the pre-transplant and 37 months in the post-transplant group. In both groups, all patients had persistent resolution of thrombocytopenia and neutropenia after embolization. In the post-transplant group, one patient had persistent splenomegaly and required splenectomy for pain control. No procedure-related complications occurred in any patient. In this limited review, PSE appears to be a safe and effective treatment of persistent hypersplenism in patients with portal hypertension and those who have undergone OLTx.
