Síndrome colestásico como forma de presentación de linfoma no Hodgkin. Reporte de un caso pediátrico / Cholestatic syndrome as a presentation of non-Hodgkin lymphoma. A pediatric case report

La ictericia colestásica se debe a la alteración de la secreción de bilirrubina conjugada; es una de las posibles causas la alteración del flujo biliar por obstrucción de la vía biliar extrahepática. El linfoma es la tercera neoplasia más frecuente en pediatría, mientras que los tumores pancreáticos son poco frecuentes y, en su mayoría, lesiones benignas. Las manifestaciones clínicas de los tumores de localización retroperitoneal son poco específicas y suelen ser tardías, por lo que la sospecha clínica debe ser alta. El objetivo del siguiente trabajo es presentar el caso de un niño de 7 años con síndrome colestásico en el que se halló un tumor en la cabeza del páncreas que comprimía la vía biliar extrahepática. El diagnóstico del tumor fue linfoma no Hodgkin (LNH). Se destaca la infrecuencia de este tumor en esta localización en la edad pediátrica

Cholestatic jaundice is due to an alteration in conjugated bilirubin secretion; a possible cause is an altered bile flow resulting from an obstruction of the extrahepatic bile duct. A lymphoma is the third most common neoplasm in pediatrics, while pancreatic tumors are rare and mostly benign. The clinical manifestations of retroperitoneal tumors are not very specific and are usually late, so a high level of clinical suspicion is required. The objective of this study is to describe the case of a 7-year-old boy with cholestatic syndrome with a tumor in the head of the pancreas compressing the extrahepatic bile duct. The tumor diagnosis was non-Hodgkin lymphoma (NHL). It is worth noting that the presence of a tumor in this location in pediatric age is uncommon

Epidemiological profile, referral routes and diagnostic accuracy of cases of acute cholangitis among individuals with obstructive jaundice admitted to a tertiary-level university hospital: a cross-sectional study

ABSTRACT BACKGROUND: Obstructive jaundice may lead to ominous complications and requires complex diagnostic evaluations and therapies that are not widely available. OBJECTIVE: To analyze the epidemiological profile, referral routes and diagnostic accuracy at admittance of cases of acute cholangitis among patients with obstructive jaundice treated at a referral unit. DESIGN AND SETTING: Cross-sectional study at a tertiary-level university hospital. METHODS: Patients with obstructive jaundice who were treated by means of endoscopic retrograde cholangiopancreatography, resection and/or surgical biliary drainage were evaluated. The main variables analyzed were epidemiological data, referral route, bilirubin levels and time elapsed between symptom onset and admittance and diagnosing of acute cholangitis at the referral unit. The accuracy of the clinical diagnosis of acute cholangitis was compared with a retrospective analysis on the medical records in accordance with the Tokyo criteria. RESULTS: Female patients predominated (58%), with an average age of 56 years. Acute cholangitis was detected in 9.9% of the individuals; application of the Tokyo criteria showed that the real prevalence was approximately 43%. The main referral route was direct contact (31.8%) and emergency care (29.7%); routing via official referral through the public healthcare system accounted for 17.6%, and internal referral from other specialties, 20%. The direct route with unofficial referral was the most important route for cases of neoplastic etiology (P < 0.01) and was the fastest route (P < 0.01). CONCLUSIONS: There is a deficiency in the official referral routes for patients with obstructive jaundice. The accuracy of the clinical diagnosis of acute cholangitis was poor. Wider dissemination of the Tokyo criteria is essential.

Primary hepatic lymphoma mimicking cholangiocarcinoma

Primary hepatic lymphoma [PHL] presenting with obstructive jaundice is rare and can mimic a preoperative diagnosis of cholangiocarcinoma. We should consider PHL in patients with radiological hepatic disease with normal serum alpha-fetoprotein and carcinoembryonic antigen levels, and elevated lactate dehydrogenase

We present the case of a 67-year-old male with no significant medical history presented with abdominal pain, jaundice, fever, and abnormal liver function tests. Abdominal sonography and computed tomography scan suggested a diagnosis of obstructive jaundice and cholangitis due to cholangiocarcinoma [Klatskin tumor]

A subsequent liver biopsy diagnosed PHL, and the patient was treated with combination chemotherapy, including rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP]. PHL should be considered in patients presenting with biliary obstruction

A case of obstructive jaundice caused by tuberculous lymphadenitis: A literature review

Obstructive jaundice caused by tuberculous lymphadenitis is a rare manifestation of tuberculosis (TB), with 15 cases having been reported in Korea. We experienced a case of obstructive jaundice caused by pericholedochal tuberculous lymphadenitis in a 30-year-old man. The patient's initial serum total bilirubin level was 21.1 mg/dL. Abdominal computed tomography revealed narrowing of the bile duct by a conglomerated soft-tissue mass involving the main portal vein. Abrupt obstruction of the common bile duct was observed on cholangiography. Pathologic analysis of a ultrasonography-guided biopsy sample revealed chronic granulomatous inflammation, and an endoscopic examination revealed esophageal varices and active duodenal ulceration, the pathology of which was chronic noncaseating granulomatous inflammation. Hepaticojejunostomy was performed and pathologic analysis of the conglomerated soft-tissue mass revealed chronic granulomatous inflammation with caseation of the lymph nodes. Tuberculous lymphadenitis should be considered in patients presenting with obstructive jaundice in an endemic area.

Ictericia colestásica inducida por metimazol en una paciente con hipertiroidismo / [Methimazole-induced cholestatic jaundice in a hyperthyroid patient].

Hyperthyroidism is one of the most frequent endocrine disorders and its current treatment is based on drugs, surgery and radioactive iodine. Methimazole is the antithyroid drug of choice because of its potency and infrequent side effects, usuaIly mild. This medication is rarely associated with liver toxicity, usually manifested as cholestatic jaundice. Here we report the case of a 33-year-old woman treated at the University Hospital Fundación Santa Fe de Bogota, with hepatotoxicity induced by a methimazole-based treatment for Graves’ disease. The pruritus and jaundice appeared after three weeks of therapy, viral hepatitis markers were negative, hepatobiliary ultrasonography was normal, and an increase of the levels of alkaline phosphatase, total bilirubin and aminotransferases was found The causal diagnosis of methimazole-induced hepatotoxicity was supported by the results of a liver biopsy. According to the CIOMS scale the score was 10, and the causal relationship of the hepatic adverse reaction by methimazole is highly probable. The clinical course was satisfactory when the medication was suspended, with clinical improvement at 5 days, and normalization of liver tests at 5 weeks. We discuss this case from a diagnostic and therapeutic approach.

One-stage percutaneous triple procedure for treatment of endoscopically unmanageable patients with malignant biliary obstruction and marked ascites

Background and study aims: To assess the feasibility, safety and efficacy of one-stage percutaneous triple procedure including; ascites drainage, primary metallic biliary stenting, and tract embolisation with N-butyl 2-cyanoacrylate [NBCA], in treatment of patients with malignant biliary obstruction and marked ascites

Patients and methods: This study involved 25 patients with malignant biliary obstruction and marked ascites [age range, 46-78 y; mean age +/- SD, 65 y +/- 5] for whom endoscopic treatment failed or was unsuitable. Ascites drainage, percutaneous primary metallic biliary stenting, and tract embolisation with lipiodol/NBCA mixture were performed in a one-stage procedure. The mean +/- SD follow up period was 26 +/- 2 weeks

Results: The technical and clinical success rates were 96% and 88% respectively. No procedure related deaths or major complications were observed. The reported minor complications included; moderate pain and vomiting during and after balloon dilation, postprocedural cholangitis, and bile leakage in 44%, 16%, and 8% of the patients respectively. Primary stent patency was achieved in 96%. The 30-days mortality was 8%. The stent obstruction occurred in 3 [13%] of the 23 patients who survived more than 30-days

Conclusions: Percutaneous drainage of ascites followed immediately by primary biliary stenting, together with tract embolisation with NBCA is technically feasible, safe, and effective alternative palliative treatment for endoscopically unmanageable patients with malignant biliary obstruction and marked ascites

Percutaneous Placement of Self-Expandable Metallic Stents in Patients with Obstructive Jaundice Secondary to Metastatic Gastric Cancer after Gastrectomy

OBJECTIVE: To evaluate the outcomes of patients undergoing percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy. MATERIALS AND METHODS: Fifty patients (mean age, 62.4 years; range, 27-86 years) who underwent percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy were included. The technical success rate, clinical success rate, complication rate, stent patency, patient survival and factors associated with stent patency were being evaluated. RESULTS: The median interval between the gastrectomy and stent placement was 23.1 months (range, 3.9-94.6 months). The 50 patients received a total of 65 stents without any major procedure-related complications. Technical success was achieved in all patients. The mean total serum bilirubin level, which had been 7.19 mg/dL +/- 6.8 before stent insertion, decreased to 4.58 mg/dL +/- 5.4 during the first week of follow-up (p < 0.001). Clinical success was achieved in 42 patients (84%). Percutaneous transhepatic biliary drainage catheters were removed from 45 patients (90%). Infectious complications were noted in two patients (4%), and stent malfunction occurred in seven patients (14%). The median stent patency was 233 +/- 99 days, and the median patient survival was 179 +/- 83 days. Total serum bilirubin level after stenting was an independent factor for stent patency (p = 0.009). CONCLUSION: Percutaneous transhepatic placement of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy is a technically feasible and clinically effective palliative procedure.

Periampullary carcinoid: An uncommon tumor at an unusual site.

Gastrointestinal carcinoid tumors represent a group of well-differentiated tumors originating from various neuroendocrine cells located in the gastrointestinal mucosa and submucosa. Consequently, there is diversity in their clinical presentation, incidence at specific anatomic sites, biological behavior, hormone production, morphologic characteristics, and immunophenotype. Periampullary carcinoids are extremely rare and less then 100 patients have been reported in the world literature, that too mostly as case reports. We are reporting two cases of periampullary carcinoids, one of which presented with rare manifestation as gastrointestinal bleed and both are doing well after successful pancreatoduodenectomy.

Hemobilia: diagnóstico por imágenes a propósito de dos casos / Hemobilia: imaging report of two cases

El diagnóstico de hemobilia resulta difícil en la práctica diaria; el tratamiento está destinado a detener el sangrado y resolver la causa del mismo. Los aneurismas de la arteria hepática constituyen una patología poco frecuente y una de las causas raras de hemobilia, la presentación clínica es inespecífica e incluye dolor abdominal, ictericia obstructiva y sangrado digestivo alto. Recientemente con el desarrollo de la radiología intervencionista se ha logrado reducir el número de cirugías, mediante la embolización transarterial, obteniendo tasas de éxito entre 80-100%.2 Se presentaran 2 casos de hemobilia, todos fueron estudiados con ecografía, colangiografía por resonancia magnética y angiotomografía. Se describen las características de esta patología con los distintos métodos por imágenes; se destaca la indicación de la arteriografía no sólo para el diagnóstico sino también como tratamiento (embolización). En un caso, la hemobilia fue identificada por duodenoscopia y en el otro por gastroscopia. A ambos pacientes se le realizó ultrasonido abdominal el cual mostró hepatomegalia, vesícula distendida con barro biliar, dilatación de vías biliares e imagen hipoecogénica en segmento V hepático. El doppler revela flujo activo en la vía biliar. Angiotomografía y colangiografía por resonancia magnetica revelaron aneurisma en la arteria hepática derecha en íntimo contacto con la vía biliar, correlacionado con la imágen hipoecogénica observada por ultrasonido. Ambos casos fueron resueltos por la liberación de coils intra-arteriales sin complicaciones.

The diagnosis of hemobilia is difficult in daily practice; treatment is designed to stop the bleeding and resolve its cause. Hepatic artery aneurysms are an uncommon condition and one of the rare causes of hemobilia; clinical presentation is nonspecific and includes abdominal pain, obstructive jaundice and upper gastrointestinal bleeding. Recently, due to the development of interventional radiology, the number of surgeries has successfully been reduced through transarterial embolization, achieving success rates between 80-100%.2 We present 2 cases of hemobilia that were evaluated by ultrasound, MRI cholangiography and angiotomography. We describe the characteristics of this disease with the use of different imaging methods; with emphasis on the use of arteriography not only for diagnosis but also for treatment (embolization). In one case, the hemobilia was identified by duodenoscopy, and in the other by gastroscopy. Both patients underwent abdominal ultrasound that showed hepatomegaly, distended gallbladder with biliary sludge, distended bile ducts and a hypoechoic image in liver segment V. Doppler revealed active flow into the bile duct. Angiotomography and MRI reported an aneurysm in the right hepatic artery in close contact to the bile duct, correlated to the hypoechoic image seen by ultrasound. Both cases were treated with transarterial coil placements without any complications.

Obstructive Jaundice Caused by Clonorchiasis-associated Duodenal Papillitis: A Case Report

We describe an unusual presentation of Clonorchis sinensis infection with obstructive jaundice due to duodenal papillitis which was relieved dramatically by endoscopic sphincterotomy. A 26-yr-old male presented with complaints of fatigue, weight loss and painless jaundice. The history was significant for frequent ingestion of raw freshwater fish. The patient underwent endoscopic retrograde cholangiopancreatography for evaluation of obstructive jaundice. The duodenal papilla was markedly edematous with a bulging configuration and hyperemic changes at the orifice. Cholangiography revealed mild bile duct dilatation and irregular wall changes with multiple indentations. However, there were no biliary stricture or stones noted as the cause of obstructive jaundice. We performed an endoscopic sphincterotomy for effective bile drainage through the duodenal papilla. After the sphincterotomy, the patient's jaundice was dramatically improved. Pathology of the duodenal papilla showed eosinophilic infiltration of the mucosa. Parasitic eggs, consistent with the diagnosis of C. sinensis, were found in the bile sample.

The Safety Assessment of Percutaneous Transhepatic Transpapillary Stent Insertion in Malignant Obstructive Jaundice: Regarding the Risk of Pancreatitis and the Effect of Preliminary Endoscopic Sphincterotomy / 대한소화기학회지

BACKGROUND/AIMS: Metal stent insertion through percutaneous transhepatic biliary drainage (PTBD) track is an important palliative treatment modality for malignant biliary obstruction. Acute pancreatitis is one of serious complications of biliary metal stenting. The purpose of this study was to investigate the risk of pancreatitis for patients who underwent metal stent insertion via PTBD track. METHODS: A retrospective analysis of 90 consecutive patients who received metal stent insertion via PTBD track from Jan. 2002 to Dec. 2007 was carried out. Patients were devided into the transpapillary and non-transpapillary group, and the risks of pancreatitis were compared. The effects of preliminary endoscopic sphincterectomy (EST) was also investigated in transpapillary group. RESULTS: The rate of pancreatitis was higher in transpapillary group compared to nontranspapillary group (odd ratio 1.87, 95% CI 0.516-6.761), but it showed no stastically significance (p=0.502). In transpapillary group, patients who received preliminary EST showed lower rate of pancreatitis (odd ratio 0.91, 95% CI 0.656-1.273), but it showed no stastically significance (p=0.614). CONCLUSIONS: Metallic stent insertion through the intact sphincter of Oddi might have a risk of developing pancreatitis. Further study is needed to elucidate the mechanism of pancreatitis and the way of prevention.

significance of ultrasound in diagnosing gallstone disease

The efficacy and sensitivity of transabdominal ultrasonography [TUS] for detecting gallstones in patients with biliary colic and biliary tract diseases was studied. A prospective study was carried out between February 2003 and February 2007, in the Surgical Department of Al-Gamhouria Teaching Hospital. Patients with Ultrasound diagnosis of gallbladder [GB] and common bile duct [CBD] stones diseases [including 2 cases with biliary colic like pain and negative TUS result] were admitted to the hospital for cholecystectomy and, in indicated cases for choledochotomy. Presence or absence of stones were noted. CT-scanning was ordered in patients with obstructive jaundice. The computer program Quickcalcs of Graphpad software was applied for data processing [http:/graphpad.com/quickcalcs]. TUS was performed on 114 consecutive patients; 103 [90.35%] were women and 11 [9.65%] were men. The ages ranged between 20 to 80 years, with mean age of 43.62 years. For gallbladder stones; there were 108 True Positive, 2 True Negative, 3 False Positive and one False Negative scans, yielding 94.74% sensitivity, 66.67% specificity, and 96.49% accuracy. Positive Predictive Value [PPV] for gallbladder stones was 16.66% and Negative Predictive Value [NPV] was 97.22%. Nine patients out of 114 [7.9%] had associated with common bile duct obstruction, 6 women [5.26%] and 3 men [2.63%], with 7 True Positive, one False Positive, and one False Negative results for choledocholithiasis, yielding 77.78% sensitivity, 92.11% specificity, and 98.25% accuracy. PPV was 45.78%, whereas NPV was 97.98%. The Ultrasound provided an effective and reliable means for the diagnosis of GB and CBD stone diseases

Etiological spectrum of obstructive Jaundice

The objective of this study was to determine the etiological spectrum of obstructive jaundice in this part of the world. This prospective study was carried out at Liaquat National Hospital, Karachi from March 1997 to February 2001 and later at Isra University Hospital, Hyderabad from January 2003 to December 2006. Sixty five patients with obstructive jaundice were included in this study. The data was collected with respect to patient's identity, age, gender and cause of the obstructive jaundice. Fifty seven percent of patient had malignant obstructive jaundice and carcinoma of head of pancreas being the leading cause of malignant obstructive jaundice. Forty three percent patients had benign causes of obstructive jaundice, choledocholithiasis being the most common benign cause. Choledocholithiasis and malignancy are the two major causes of obstructive jaundice

Obstructive Jaundice due to Compression of the Common Bile Duct by Right Hepatic Artery Originated from Gastroduodenal Artery / 대한소화기학회지

Obstructive jaundice by vascular compression is rare. The causative arteries were identified as the right hepatic artery, gastroduodenal artery, cystic artery, proper hepatic artery, and an unspecified branch of the common hepatic artery. Also the venous system, such as enlarging collateral veins in cases of portal hypertension was a causative vessel. Herein, we describe a case of a proximal choledocholithiasis due to compression of the common bile duct by right hepatic artery originated from gastroduodenal artery. Final diagnosis and treatment were achieved through an operation.
