Jaundice-Should "yellow" be a red code?

Objective: Jaundice is the clinical manifestation, of hyperbilirubinemia. It is considered as a sign of either a liver disease or, less often, of a hemolytic disorder. It can be divided into obstructive and non obstructive type, involving increase of indirect (non-conjugated) bilirubin or increase of direct (conjugated) bilirubin, respectively, but it can be also manifested as mixed type. Methods: This article updates the current knoweledge concerning the jaundice's etiology, pathophysiological mechanisms, and complications ant treatment by reviewing of the latest medical literature. It also presents an approach of jaundice's treatment and pathogenesis, in special populations as in neonates and pregnant women. Results: The treatment is consistent in the management of the subjective diseases responsible for the jaundice and its complications.The clinical prognosis of the jaundice depends on the etiology. Surgical treatment of jaundiced patients is associated with high mortality and morbidity rates. Studies have shown that the severity of jaundice and the presence of malignant disease are importan risk factors for post-operative mortality. Conclusions: Early detection of jaundice is of vital importance because of its involvement in malignancy or in other benign conditions requiring immediate treatment in order to avoid further complications.

La maladie liée aux IgG4: une cause possible d'ictère obstructif [IgG4-related disease: a possible cause of obstructive jaundice].

Immunoglobulin G4 related disease (IgG4-RD) has been recognized since early 2000s as an entity comprising a set of inflammatory diseases with common histopathological features. The disease may affect almost all organs and tissues, and often occurs in a subacute fashion in males over 50 years as a mass or diffuse enlargement of affected organs. The histopathological appearance is characterized by a lymphoplasmacytic infiltration with predominantly IgG4-positive plasma cells and progressive fibrosis. Its clinical and radiological features can make the distinction with a malignancy difficult. The disease responds well to systemic glucocorticoids however with a high rate of recurrence after treatment discontinuation.

Simultaneous biliary drainage and portal vein embolization before extended hepatectomy for hilar cholangiocarcinoma: preliminary experience.

BACKGROUND: Patients with resectable hilar cholangiocarcinoma often present obstructive jaundice and a small future remnant liver (FRL) ratio. A sequential approach comprising preoperative biliary drainage followed by portal vein embolization (PVE) is usually performed but leads to long preoperative management (6-12 weeks) before patients can undergo resection. To simplify and shorten this phase of liver preparation, we developed a new preoperative approach that involves percutaneous biliary drainage and PVE during the same procedure. We report the outcomes of this combined procedure. METHODS: During 1 year, four patients underwent simultaneous biliary drainage and PVE followed 1 month later by surgical resection of hilar cholangiocarcinoma. Liver volumes were assessed by CT before, and 1, and 3 months after the combined procedure. Serum liver enzymes were assessed before and 1 month after the combined procedure. RESULTS: The combined procedure was feasible in all cases, with no related complications. After the combined procedure, transaminases remained stable or decreased, whereas gamma-glutamyl-transpeptidase, alkaline phosphatase, and bilirubin decreased. During the first month, the left lobe volume increased by +27.9 % (range 19-40.9 %). The FRL ratio increased from 24.9 to 33.2 %. All patients underwent R0 liver resection with a favorable postoperative outcome. The remnant liver volume increased by +132 % (range 78-245 %) between 1 and 3 months. CONCLUSIONS: Simultaneous percutaneous biliary drainage and PVE is feasible. This all-in-one preoperative approach greatly decreases waiting time until surgical resection. These encouraging results warrant further investigation to confirm the safety and to evaluate the reduction in the dropout rate for liver resection in this tumor with poor prognosis.

Maladie de Weil: à propos d'un cas de leptospirose acquise en Suisse [Weil's disease: a case report of acquired leptospirosis in Switzerland].

Leptospirosis is a rare disease in Switzerland. However its incidence is probably underestimated, due to its broad spectrum of presentations, including subclinical benign forms and the ictero-hemorragic form of the Weil's syndrome, whose mortality is high. We describe here a case of Weil's syndrome acquired in Switzerland with a favourable outcome under antibiotherapy. Even in the absence of any travel, the association of an acute renal insufficiency and jaundice with only moderate hepatic cytolysis should lead to the suspicion of leptospirosis. Clinical and epidemiological aspects of the disease are discussed in the article.

The 5th anniversary of "Patient Safety in Surgery" - from the Journal's origin to its future vision.

A prospective study was undertaken to determine prognostic markers for patients with obstructive jaundice. Along with routine liver function tests, antipyrine clearance was determined in 20 patients. Four patients died after basal investigations. Five patients underwent definitive surgery. The remaining 11 patients were subjected to percutaneous transhepatic biliary decompression. Four patients died during the drainage period, while surgery was carried out for seven patients within 1-3 weeks of drainage. Of 20 patients, only six patients survived. Basal liver function tests were comparable in survivors and nonsurvivors. Discriminant analysis of the basal data revealed that plasma bilirubin, proteins and antipyrine half-life taken together had a strong association with mortality. A mathematical equation was derived using these variables and a score was computed for each patient. It was observed that a score value greater than or equal to 0.84 indicated survival. Omission of antipyrine half-life from the data, however, resulted in prediction of false security in 55% of patients. This study highlights the importance of addition of antipyrine elimination test to the routine liver function tests for precise identification of high risk patients.

Enzyme polymorphism and clinical variability of diseases: a study of diabetes mellitus.

We investigated possible relations among four common neonatal manifestations of diabetic pregnancy (macrosomia, hypoglycemia, hypocalcemia, jaundice) and four enzyme polymorphisms (PGM1, ADA, AK1, ACP1 in a sample of infants born of diabetic mothers. The pattern of associations observed between the two sets of variables is consistent with known differences in enzymatic activity within phenotypes of each system, suggesting that low enzymatic activity may have unfavorable effects on fetal development and on adaptability of the neonate to the extrauterine environment, Some of the polymorphic enzymes studied influence fetal growth in normal pregnancy as well. Analysis of relations between genetic polymorphisms and the clinical pattern of common diseases may provide a better understanding of the genetic basis of the clinical variability of diseases within and between human populations.

Budd-Chiari syndrome due to prothrombotic disorder: mid-term patency and efficacy of endovascular stents.

Our objective was to evaluate efficacy and patency of metallic stent placement for symptomatic Budd-Chiari syndrome (BCS) due to prothrombotic disorders. Eleven patients with proved BCS due to prothrombotic disorders were referred for endovascular treatment because of refractory ascites (n=9), abdominal pain (n=8), jaundice (n=6), and/or gastrointestinal bleeding (n=4). Stents were inserted for stenosed hepatic vein (n=7), inferior vena cava (n=2), or mesenterico-caval shunt (n=2). Clinical efficacy and stent patency was evaluated by clinical and Doppler follow-up. After a mean follow-up of 21 months, 6 patients had fully patent stents without reintervention (primary stent patency: 55%). Two patients with hepatic vein stenosis had stent thrombosis and died 4 months after procedure. Restenosis occurred in 3 cases (2 hepatic vein and 1 mesenterico-caval shunt stenosis) and were successfully treated by balloon angioplasty (n=2) and addition of new stents (n=1) leading to a 82% secondary stent patency. Of 9 patients with patent stent, 7 were asymptomatic (77%) at the end of the study. Stent placement is a safe and effective procedure to control of symptomatic BCS. Prothrombotic disorder does not seem to jeopardize patency in anticoagulated patients.
