| 1 | Small diameter H-graft porta-caval shunt performed at different stages of liver disease显示文摘BACKGROUND: Partial porto-systemic shunts have been popularized because of reported low rate of mortality and morbidity (especially encephalopathy, liver failure and oc- clusion). To further investigate these assumptions, we ret- rospectively reviewed the results of partial porta-caval shunts performed at different stages of liver disease. METHODS: Twenty-nine cirrhotic patients underwent a partial porta-caval shunt with a ringed polytetrafluoroethy- lene interposition prosthesis of 8-mm ( 20 patients) or 10- mm (9 patients) in diameter. Pre- and post-shunt porta- caval pressure was measured in all patients. Twelve patients (41.4%) belonged to Child A, 11 Child B (37.9%), and 6 Child C (20.7%). Eleven patients (37.9%) suffered from hepatic encephalopathy preoperatively. Twelve patients (41%) were operated on in emergency/urgency. RESULTS: Porta-caval pressure gradient, reduced signifi- cantly using either 8- or 10-mm prosthesis. The overall ear- ly mortality and morbidity were 13. 8% and 48% respec- tively. The early mortality and morbidity were different be- tween patients of Child A and B when compared to those of Child C (0 vs 66.6% and 34.8% vs 66.6% respectively). No patient re-bled early from varices. The overall late mor- tality and morbidity were 40% and 64% respectively. Shunt thrombosis and stenosis took place in 16% and 8% of the two groups of patients respectively; variceal re-bleeding oc- curred in 4 patients (16%). Encephalopathy occurred post- operatively in 5 patients (20%), acute in 3 patients (12%), and chronic in 2 (8%). The actuarial survival rate at 3 and 5 years was 92% and 75% for patients of Child A, 70% and 60% for patients of Child B, and 0% for patients of Child C. CONCLUSIONS: Our results indicate that partial porta-ca- val shunt with a small diameter interposition H-graft is an effective procedure for the treatment of variceal bleeding, as well as for the prevention of re-bleeding in patients of Child A and those of Child B, as an elective or emergency/ urgency procedure, with a low rate of complications and encephalopathy. This technique could be used safely in pa- tients with good liver function but they should be moni- tored closely because of the risk of shunt occlusion. | Giacomo Batignani Francesco Vizzutti Luigi Rega Michele Zuckermann Geri Fratini Massimo Pinzani Francesco Tonelli | 2004 | Hepatobiliary & Pancreatic Diseases International2004，3，4： | 1 |

| 3 | Peripancreatic paraganglioma:Lesson from a round table显示文摘We described the case of a peripancreatic paraganglioma(PGL)misdiagnosed as pancreatic lesion.Surgical exploration revealed an unremarkable pancreas and a large well-defined cystic mass originating at the mesocolon root.Radical enucleation of the mass was performed,preserving the pancreatic tail.Histologically,a diagnosis of PGL was rendered.Interestingly,two previously unreported mutations,one affecting the KDR gene in exon 7 and another on the JAK3 gene in exon 4 were detected.Both mutations are known to be pathogenetic.Imaging and cytologic findings were blindly reviewed by an expert panel of clinicians,radiologists,and pathologists to identify possible causes of the misdiagnosis.The major issue was lack of evidence of a cleavage plane from the pancreas at imaging,which prompted radiologists to establish an intraparenchymal origin.The blinded revision shifted the diagnosis towards an extrapancreatic lesion,as the pancreatic parenchyma showed no structural alterations and no dislocation of the Wirsung duct.Ex post,the identified biases were the emergency setting of the radiologic examination and the very thin mesocolon sheet,which hindered clear definition of the lesion borders.Original endoscopic ultrasonography diagnosis was confirmed,emphasizing the intrinsic limit of this technique in detecting large masses.Finally,pathologic review favored a diagnosis of PGL due to the morphological features and immonohistochemical profile.Eighteen months after tumor excision,the patient is asymptomatic with no disease relapse evident by either radiology or laboratory tests.Our report strongly highlights the difficulties in rendering an accurate preoperative diagnosis of PGL. | Federica Petrelli Geri Fratini Andrea Sbrozzi-Vanni Andrea Giusti Raffele Manta Claudio Vignali Gabriella Nesi Andrea Amorosi Andrea Cavazzana Marco Arganini Maria Raffaella Ambrosio | 2022 | World Journal of Gastroenterology2022，28，21： | 0 |
