The frequency of splenic vein obstruction secondary to pancreatic or retroperitoneal diseases has been only recently appreciated. The diagnosis is important because it frequently results in development of gastric and duodenal varices. It is often assumed that the diagnosis should only be suspected in patients with splenomegaly. This report describes 19 patients in whom splenic vein thrombosis was diagnosed by angiography although clinically unsuspected. In 11, the spleen was normal in size although extensive gastric varices were present. In 3 patients the presenting problem was massive hematemesis. Review of the upper gastrointestinal examinations in these patients showed thickened gastric or duodenal folds although in the absence of esophageal varices, the diagnosis was not made prior to angiography. More liberal use of angiography in patients with an appropriate clinical background, such as a history of pancreatitis, may lead to earlier and more frequent diagnosis of splenic vein obstruction. Varices that result from splenic vein obstruction can be cured by splenectomy.

Of 21 patients with cirrhosis of the liver 9 had collateral arterial flow to the liver from the superior mesenteric artery. The degree of collateral arterial flow in cirrhosis was related to the presence of centrifugal portal flow, the degree of bilirubinemia and the presence of a markedly enlarged spleen with increased splenic blood flow. Of 27 non-cirrhotic 6 had collateral arterial flow to the liver from the superior mesenteric artery. The greatest degree of collateral arterial flow was associated with celiac stenosis in 4/6 patients. One patient had pancreatitis and an explanation was not evident in one patient.

Ultrasonic assessment of the pancreas is rendered difficult by interposed gas-containing loops of bowel and stomach. In 50% of the cases, meteorism and ileus prevent the diagnosis of acute pancreatitis. In the case of chronic pancreatitis, focal pancreatitis and carcinoma of the pancreas, too, further diagnostic procedures (CT, ERCP, fine-needle aspiration) are required. As a rule, the caliber of the pancreatic duct can readily be assessed, and may, for example, indicate a carcinoma in the head of the pancreas. Splenomegaly and focal or diffuse parenchymal lesions are detectable by ultrasonography, although an etiological differentiation is not usually possible. The most common lesions are the so-called "bland" splenic cysts. Of importance is the diagnosis of rupture of the spleen, which requires immediate treatment.

Biliary mucinous cystadenocarcinoma is an extremely rare tumour. Less than 50 cases have been reported. It is usually a multilocular cystic tumour covered with mucous producing epithelium, with papillary excrescences containing mucinous mass arising from bile ducts. The size of the tumour varies from 3.5 to 25 cm in diameter. It is more frequent in women. The majority of patients belong to the middle age population. We present a 63-year-old man who had been suffering from an epigastric and right subcostal pain of unknown aetiology for over 35 years. During the last 10 years he suffered from multiple attacks of cholangitis with high temperature, rigor, chills, pain and obstructive jaundice. Five years ago he had the attack of pancreatitis with retroperitoneal fatty necrosis for which he was operated on in another institution and cholecystectomy and pancreatic necrectomy were carried out. The attacks of cholangitis continued they were more serious and more frequent until June 1987, when the "cyst" in the left lobe of the liver, dilated bile ducts and "polyps" in the common bile duct were diagnosed by ultrasonography. During the operation advanced biliary cirrhosis, portal hypertension, splenomegaly, very dilated common bile duct full of jelly and the "cyst" in the liver filled with jelly, were found. The removal of the jelly and choledochojejunostomy resulted in temporary relief. Two months later he was reoperated for recurrent obstructive jaundice during which left lobectomy, partial excision of the cyst and cystojejunostomy between the rest of the cyst and another Roux-en-Y jejunal limb, were carried out.(ABSTRACT TRUNCATED AT 250 WORDS)

Splenectomy for massive splenomegaly and hypersplenism carries a significant morbidity and mortality. We have used partial splenic embolization (PSE) as an effective alternative to splenectomy. Ten PSE procedures were performed on nine patients without mortality and with minimal morbidity. The age of the patients ranged from 8 months to 32 years (mean 14 years). The causes of splenomegaly and hypersplenism included cystic fibrosis with cirrhosis (2), tyrosinemia and cirrhosis (1); thalassemia (1), hemophilia with Human Immune Deficiency Virus infection (2), chronic hepatitis with portal hypertension (1), malignant histiocytosis (1), and Wiskott-Aldrich Syndrome (1). All procedures were performed under local anesthesia with sedation. A percutaneous femoral artery approach to the splenic artery was used to deliver Ivalon sponge particles (280-800 microns) into the spleen. Splenic infarction was assessed by postembolization angiograms. All of the patients except one demonstrated improvement of hematologic parameters. In one patient, however, cytopenia improved only after a second embolization. In the total series, there was an early mean rise of 8,600/mm3 in the leukocyte count (range 2,900-14,900) and 212,000/mm3 in the platelet count (range 30,000-718,000). Follow-up ranged from 4 months to 7 years. Improvement of the blood picture has been persistent in seven of the eight patients who showed initial improvement. Transient procedural complications included fever (5), pleural effusion (2), pneumonia (1), and splenic abscess (1). One patient had paralytic ileus lasting for 10 days and one patient developed a streptococcal peritonitis 3 weeks after embolization. No patient developed pancreatitis or vascular compromise of other abdominal viscera.(ABSTRACT TRUNCATED AT 250 WORDS)

During a period of 19 months, 22 organ preserving splenic operations were performed. Eleven of these, were severe third degree traumatic bursting ruptures, which were treated using a resorbable compressive mesh. An intralienal pancreatic cyst, a case of splenomegaly suspicious for lymphoma, one traumatic and two accidental polar lesions were treated by partial splenic resection using stapler. In two patients with traumatic and four with accidental first and second degree lienal lesions, collagen tampon and fibrin adhesive were employed. None of these patients required a second laparotomy. Aside from an edematous tail pancreatitis, no complications arose. Two patients succumbed to their severe cranial injuries. In the same period, four posttraumatic splenectomies were performed. Thus, excluding incidental and technical splenectomies, the application of the described methods resulted in orthotopic splenic preservation in 78% of traumatic splenic ruptures.

The most common cause of occlusion of the splenic vein is pancreatic disease, such as pancreatitis or carcinoma of the pancreas. As compared with benign causes, carcinoma of the pancreatic body or tail may readily involve not only the splenic vein, but also, eventually, the splenic artery. Therefore, the clinical features of occlusion of the splenic vein may be profoundly altered according to the nature of the underlying causes. In an attempt to clarify the pathophysiologic findings and hemodynamic mechanism of occlusion of the splenic vein associated with carcinoma of the pancreas, three patient reports were selected from our past experience. Upon analyzing the clinical course of these patients, three consecutive phases may be distinguished. Phase 1 is the insidious or latent phase represented by Patient No. 1. The splenic vein is partially occluded and gastric varices or splenomegaly has not developed. Phase 2, the collateral developing phase, is represented by Patient No. 2. The splenic vein is completely occluded while the splenic artery is patent, resulting in marked gastric varices and splenomegaly. Phase 3 is the vanishing phase and is represented by Patient No. 3. The occlusion of the splenic artery is superimposed on the occlusion of the splenic vein, causing gastric varices to vanish and the enlarged spleen to shrink.

Postoperative treatment after pancreas surgery is concentrated on the function of the exocrine and endocrine part of the gland. While functional disturbances of the endocrine pancreas may give rise to serious problems associated with diabetes, functional disturbances of the exocrine pancreas are less important. On the other hand, flow disorders of the exocrine pancreas may lead to pancreatitis, fistulas, cysts, and abdominal sepsis. Pancreatic tumours are not infrequently apudomas whose biology has an important bearing on the after-treatment. Thrombophlebitic splenomegaly may lead to portal and possibly to segmental portal hypertension. In this event, a careful follow-up examination will be needed to decide whether further surgery is necessary.

Essential thrombocythemia (ET) in an 11-year-old dog was characterized by persistently high platelet counts (range, 4.19 X 10(6)/microliters to 4.95 X 10(6)/microliters, abnormal platelet morphology, marked megakaryocytic hyperplasia in the bone marrow, absence of circulating megakaryoblasts, and history of splenomegaly and gastrointestinal bleeding. Increased numbers of megakaryocytes and megakaryoblasts (15% to 20%) in the bone marrow were confirmed by a positive acetylcholinesterase reaction. Another significant finding was the presence of a basophilia in blood (4,836/microliters) and bone marrow. The marked persistent thrombocytosis, absence of reactive (secondary) thrombocytosis, abnormal platelet morphology, and quantitative and qualitative changes in the megakaryocytic series in the bone marrow suggested the presence of a myeloproliferative disease. Cytochemical and ultrastructural findings aided in the diagnosis of ET. The dog was treated with radiophosphorus. The results was a rapid decline in the numbers of megakaryoblasts and megakaryocytes in the bone marrow and platelets and basophils in the peripheral blood. The dog died unexpectedly of acute necrotizing pancreatitis and diabetes mellitus before a complete remission was achieved.

The purpose of this study is to clarify the clinicopathophysiology of splenic vein occlusion due to pancreatic disease from hemodynamic points of view. We reviewed the angiographic findings and medical records of 82 patients who had pancreatitis, pancreatic cyst or pancreatic cancer in the pancreatic body and tail. According to the site of occlusion in 16 patients with complete splenic vein occlusion, this entity may be divided into two categories: Type A, an occlusion close to the spleen in which short-gastric system seems to be major collateral, and Type B, an occlusion distant from splenic hilum in which gastroepiploic system becomes prominent as collateral. As compared to 7 patients with incomplete splenic vein occlusion, gastric varices and splenomegaly were frequently observed with the patients having complete occlusion. Among these 16 patients, splenic arterial occlusion was superimposed in 3 patients with pancreatic cancer in whom gastric varices were not detected. Thus, clinical features of this entity must be carefully assessed according to the nature of the underlying disease. Based on these observations, three consecutive phases: Phase 1 Insiduous or latent phase, Phase 2 Collateral developing phase, Phase 3 Vanishing phase may be distinguished for splenic vein occlusion secondary to pancreatic disease.
