1/19. Emergency and elective surgical treatment of portal hypertension. A review of 23 years' experience.A retrospective review of surgical treatment for portal hypertension during a 23-year period in a regional unit is reported and the immediate and subsequent management of patients with bleeding oesophageal varices is discussed. Fifty-four patients with recurrent varix haemorrhage uncontrolled by conservative methods have been treated by oesophageal transection with a mortality of 22.2% (26.6% for cirrhotic patients). Thirty-two per cent of the cirrhotics were alive after 2 years. Only a minority (12%) of the survivors were considered suitable for a subsequent shunt procedure. Therapeutic portacaval anastomosis has been performed on 65 patients with a 51.2% 5-year survival (43-5% for cirrhotic patients). Further haemorrhage due to shunt thrombosis occurred in 5-3% of cases. The frequent occurrence of portal-systemic encephalopathy, increasing with duration of time following a shunt, is emphasized. The high morbidity and mortality in the poor-risk cirrhotic indicated that this type of patient is unsuitable for a portal-systemic shunt and is better treated by medical means.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/19. Ectopic intestinal varices as a rare cause of lower gastrointestinal haemorrhage.Ectopic intestinal varices are rarely responsible for lower gastrointestinal (GI) haemorrhage. A case of 55 years old male with recurrent melena is being presented, who was found to have scattered varices on small as well as large intestine. Selective review of literature regarding presentation, diagnosis and management of these cases is also part of presentation.- - - - - - - - - - ranking = 30.869182768253keywords = gastrointestinal haemorrhage, haemorrhage (Clic here for more details about this article) |
3/19. Transjugular intrahepatic portosystemic shunt for the treatment of portal hypertension secondary to non-cirrhotic perisinusoidal hepatic fibrosis.Non-cirrhotic perisinusoidal hepatic fibrosis is a process of imprecise pathogenesis involving collagenization of the space of Disse. Exposure to chemicals, auto-immunity, thrombophilia and/or infections are suspected primary agents. Here, we present the case of a patient who developed severe portal hypertension with histological features suggesting a non-cirrhotic perisinusoidal hepatic fibrosis. A 52-year-old man was hospitalized for oesophageal variceal haemorrhage. liver cirrhosis or portal vein thrombosis were absent as attested by laboratory tests, duplex sonography, computed tomography scan and histological examination of a liver biopsy specimen. Presinusoidal portal hypertension was suggested by a normal wedge-free hepatic vein gradient. Only electron microscopy examination of a liver biopsy specimen could disclose perisinusoidal fibrosis. This was most probably secondary to a combined chemotherapy received 4 years earlier for non-Hodgkin large-cell lymphoma. As variceal ligation failed to control oesophageal varices while liver function tests were normal, a transjugular intrahepatic portosystemic shunt (TIPS) was performed. This dramatically improved the signs of portal hypertension. This case illustrates the use of TIPS in the treatment of portal hypertension secondary to non-cirrhotic perisinusoidal fibrosis.- - - - - - - - - - ranking = 0.5keywords = haemorrhage (Clic here for more details about this article) |
4/19. Pancreatic carcinoma presenting as bleeding from segmental gastric varices: pitfalls in diagnosis.splenic vein occlusion leading to gastric variceal haemorrhage should be considered in cases of obscure upper gastrointestinal bleeding. We report an unusual case in which the underlying pathology was a resectable carcinoma of the pancreatic tail.- - - - - - - - - - ranking = 0.5keywords = haemorrhage (Clic here for more details about this article) |
5/19. Fatal variceal haemorrhage after paracetamol overdose.A patient is described where oesophageal varices developed and bled 13 days after a paracetamol overdose. The bleeding was unresponsive to medical management and proved fatal. There was no evidence that the patient had pre-existing liver disease. At necropsy the liver showed severe acute parenchymal necrosis but chronic lesions were absent. The portal vein and hepatic veins were patent.- - - - - - - - - - ranking = 2keywords = haemorrhage (Clic here for more details about this article) |
6/19. Oesophageal varices associated with busulphan-thioguanine combination therapy for chronic myeloid leukaemia.5 patients receiving continuous busulphan and 6-thioguanine for chronic myeloid leukaemia (CML) were found to have oesophageal varices associated with abnormal liver function tests. 3 of these cases presented with gastrointestinal haemorrhage and 1 patient died. The 2 other cases had varices discovered at endoscopy. Nodular regenerative hyperplasia (NRH) of the liver was identified as the cause of portal hypertension in the 4 patients on whom liver biopsies were done. The administration of busulphan and thioguanine in combination is likely to be associated with the development of NRH, with portal hypertension and oesophageal varices occurring in a substantial proportion of cases.- - - - - - - - - - ranking = 7.5922956920633keywords = gastrointestinal haemorrhage, haemorrhage (Clic here for more details about this article) |
7/19. Repeated shunt surgery in a patient with portal hypertension.A 45-year-old male with chronic active hepatitis and portal hypertension had a mesocaval interposition graft performed because of repeated uncontrolled bleeding from oesophageal varices. Acute hepatocellular failure, manifested by Grade IV encephalopathy and severe coagulopathy, developed early in the post-operative course despite the absence of hepatic necrosis or other precipitating factors. Both encephalopathy and coagulopathy resolved rapidly following ligation of the shunt. Variceal bleeding recurred and nine months later an emergency distal lienorenal shunt was performed. Post-operatively the shunt was shown to be patent and there has been no encephalopathy or recurrence of variceal bleeding. It is concluded that (1) the splanchnic haemodynamic effects of a mesocaval interposition graft can result in severe hepatocellular failure and this can be reverted by shunt ligation and (2) the distal lienorenal shunt, while effectively reducing the risk of haemorrhage from varices, may be less likely to result in post-operative encephalopathy than more conventional forms of portal decompressive surgery.- - - - - - - - - - ranking = 0.5keywords = haemorrhage (Clic here for more details about this article) |
8/19. Bleeding colonic varices controlled by propranolol.A 64-year-old man with hepatic cirrhosis developed severe haemorrhage from oesophageal varices. He underwent a course of sclerotherapy injections which successfully obliterated the oesophageal varices and prevented further oesophageal bleeding. He later developed serious bleeding from a site in the region of the ascending colon; angiography and radionuclide imaging suggested that varices were present in that region. Therapy with oral propranolol was effective in preventing any recurrence of gastrointestinal bleeding.- - - - - - - - - - ranking = 0.5keywords = haemorrhage (Clic here for more details about this article) |
9/19. Bilateral gastric venous decompression by a modified Warren shunt.A new modification of the Warren shunt by which the coronary and short gastric venous systems can be simultaneously decompressed was carried out on two patients with oesophagogastric varices due to liver cirrhosis. One was an elective and the other an emergency operation. The left gastric vein entering the splenic vein was also drained through a Gore-Tex graft between the splenic and left renal veins. The proximal end of the splenic vein was ligated at its junction to the superior mesenteric vein. Porta-azygos disconnection was achieved by ligating the right gastric and gastro-epiploic veins. The shunt was patent and its effect on the varices was immediate with good decompression in both patients. The patients have had no recurrent variceal haemorrhage or postshunt encephalopathy. This modification may be indicated for selected patients with portal hypertension for both elective and emergency operations.- - - - - - - - - - ranking = 0.5keywords = haemorrhage (Clic here for more details about this article) |
10/19. Development of cutaneous gangrene during continuous peripheral infusion of vasopressin.Five patients given vasopressin by infusion to reduce portal hypertension developed signs of cutaneous gangrene 18-24 hours after the start of the infusion. Four patients were treated by application of local dressings; in three cases the lesions healed, but the fourth patient died from variceal haemorrhage. The remaining patient required split skin grafting but died 48 hours after operation. The mechanism of this effect of vasopressin is not clear, but if local blanching of the skin is noted during infusion the catheter should be flushed immediately with a vasodilator in an effort to counteract the drug's vasoconstrictor effect.- - - - - - - - - - ranking = 0.5keywords = haemorrhage (Clic here for more details about this article) |
