Okamoto T. Malignant biliary obstruction due to metastatic non-hepato-pancreato-biliary cancer. World J Gastroenterol 2022; 28:985-1008. [PMID: 35431494 PMCID: PMC8968522 DOI: 10.3748/wjg.v28.i10.985] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 07/03/2021] [Accepted: 02/16/2022] [Indexed: 02/06/2023] Open
Abstract
Malignant biliary obstruction generally results from primary malignancies of the pancreatic head, bile duct, gallbladder, liver, and ampulla of Vater. Metastatic lesions from other primaries to these organs or nearby lymph nodes are rarer causes of biliary obstruction. The most common primaries include renal cancer, lung cancer, gastric cancer, colorectal cancer, breast cancer, lymphoma, and melanoma. They may be difficult to differentiate from primary hepato-pancreato-biliary cancer based on imaging studies, or even on biopsy. There is also no consensus on the optimal method of treatment, including the feasibility and effectiveness of endoscopic intervention or surgery. A thorough review of the literature on pancreato-biliary metastases and malignant biliary obstruction due to metastatic non-hepato-pancreato-biliary cancer is presented. The diagnostic modality and clinical characteristics may differ significantly depending on the type of primary cancer. Different primaries also cause malignant biliary obstruction in different ways, including direct invasion, pancreatic or biliary metastasis, hilar lymph node metastasis, liver metastasis, and peritoneal carcinomatosis. Metastasectomy may hold promise for some types of pancreato-biliary metastases. This review aims to elucidate the current knowledge in this area, which has received sparse attention in the past. The aging population, advances in diagnostic imaging, and improved treatment options may lead to an increase in these rare occurrences going forward.

Ultrasound for patients in a high HIV/tuberculosis prevalence setting: a needs assessment and review of focused applications for Sub-Saharan Africa. Int J Infect Dis 2016; 56:229-236.

Abstract
Ultrasound is increasingly used in point-of-care applications and has great potential to support the diagnosis of infectious diseases, especially in resource-limited settings. A cross-sectional study was performed involving 100 Malawian patients with a clinical indication for ultrasound. Furthermore, the literature on point-of-care ultrasound (POCUS) in Sub-Saharan Africa was reviewed to establish its applicability, most frequent indications, findings, and implications for treatment, and therefore relevance in POCUS curricula, with a main focus on infectious diseases. In Malawi, the main indications for ultrasound were weight loss, abdominal pain, and shortness of breath. Abnormal findings were observed in 77% of patients, the most common being enlarged abdominal lymph nodes (n=17), pericardial effusion (n=15), splenic microabscesses (n=15), and pleural effusion (n=14). POCUS led to a change in treatment in 72% of patients. The literature on the various POCUS applications used in Malawi was reviewed, including focused assessment with sonography for HIV-associated TB (FASH), heart, liver, kidney, deep venous thrombosis (DVT), and gynaecology. Based on disease prevalence, impact of POCUS on treatment, and technical difficulty, it is proposed that FASH, heart, and DVT are the most relevant POCUS applications in comparable Sub-Saharan African settings and should be incorporated in POCUS curricula.

Abstract
We herein describe a case of progressive human immunodeficiency virus (HIV)-associated cholangiopathy despite normalization of laboratory parameters, which had indicated liver dysfunction, after the initiation of combined anti-retroviral therapy (cART). HIV-associated cholangiopathy remains important as a differential diagnosis of bile duct disorders, although it is considered to be a rare disease in the era of cART. Magnetic resonance cholangiopancreatography could thus be a powerful tool for the diagnosis and follow-up of this disease.

Abstract
AIDS-associated cholangiopathy is a form of biliary tract inflammation with stricture formation seen in AIDS patients who are severely immunosuppressed. It is no longer common in countries in which HAART therapy is widely employed but is still seen in underdeveloped countries. The majority of patients are symptomatic at the time of presentation. Herein, we describe a seventy-four-year-old woman who presented with unilateral leg swelling after a prolonged airplane flight. She was otherwise entirely asymptomatic. Routine laboratory testing was notable for a hypochromic microcytic anemia, slight leukopenia, and mild hypoalbuminemia. Liver enzymes were all elevated. Deep venous thrombosis was confirmed, and a CT scan of the chest disclosed no pulmonary emboli. However, the visualized portion of the abdomen showed dilatation of the common bile and pancreatic ducts. This was confirmed on ultrasonography and MRCP, and no obstructive lesions were noted. An ERCP revealed a dilated common bile duct without filling defects or strictures. A balloon occlusion cholangiogram showed strictures and beading of the intrahepatic ducts. Shortly thereafter, serology for HIV returned positive along with a depressed CD4 cell count, and the patient was diagnosed with AIDS-associated cholangiography.

Abstract
BACKGROUND Cancer metastatic to the pancreas from other primary sites is uncommon, and it has been treated with an aggressive surgical approach in fit patients when the primary tumor is controlled and the pancreas is the only site of metastatic disease. The value of pancreatic resection in this setting is unclear. The purpose of this study was to review cases of cancer metastatic to the pancreas. METHODS We reviewed our experience with cancer metastatic to the pancreas and the literature regarding resection of pancreatic metastases. Patient and tumor characteristics were summarized using descriptive statistics. RESULTS A total of 220 patients with pancreatic metastasis were analyzed. Three patients were selected from our own experience, and 217 were selected from a literature review. In the 127 patients whose symptoms were recorded at the time of presentation, the most common presenting symptoms were jaundice (n=32, 25.2%) and abdominal pain (n=25, 19.7%). In the 189 patients for whom the location of the metastasis in the pancreas was revealed, the most common location was the head of the pancreas (n=79, 41.8%). The primary tumor site was most commonly kidney (n=155, 70.5%). Surgical resection was attempted in 177 of 220 patients; 135 patients suffering from renal cell carcinoma (RCC) metastasis also underwent pancreatic resection. In the latter group, a median survival of 70 mo was seen, as well as 78% and 65% 2- and 5 y survival rates, respectively. CONCLUSION Survival after resection of RCC with isolated metastasis to the pancreas is favorable. However, a more detailed analysis considering outcomes without surgery for each primary tumor site is needed before the value of this aggressive surgical approach can be completely assessed in the general occurrence of pancreatic metastasis.

Abstract
OBJECTIVE The purpose of this article is to describe the spectrum of MRI and MR cholangiopancreatography (MRCP) findings of hepatic, pancreatic, and biliary manifestations in patients with HIV infection. CONCLUSION The spectrum of MRI and MRCP findings in HIV-infected patients includes acute or chronic hepatitis (or both), pancreatitis, cholangitis, acalculous cholecystitis, and biliary strictures that may resemble primary sclerosing cholangitis. The presence of segmental extrahepatic biliary strictures is characteristic of AIDS cholangiopathy.

Abstract
One thousand and eighty-one evaluable HIV-infected patients were assessed for pancreatic abnormalities in a prospective case-control study including the whole follow-up period of each patient (minimum 12 months). The 435 patients (40.2%), who experienced at least one episode of confirmed pancreatic laboratory abnormality had a longer duration of seropositivity, exposure to protease inhibitors, a more frequent immunodeficiency, AIDS, chronic liver and/or biliary disease and hypertriglyceridaemia, while no relation was found with antiretroviral administration, and the duration of type of nucleoside analogues, when compared with the 646 controls. High and prolonged laboratory alterations eventually associated with signs of organ involvement occurred in 166 cases (38.2%), and were related to the administration of didanosine, stavudine, lamivudine, pentamidine, cotrimoxazole or antitubercular/antimycobacterial therapy, cytotoxic chemotherapy, illicit substance or alcohol abuse, opportunistic infections, chronic liver and/or biliary disease, a protease inhibitor-based highly active antiretroviral therapy (HAART) and hypertriglyceridaemia (usually associated with HAART administration). No difference was noticed between the 46 patients with clinical and/or imaging evidence of pancreatic involvement and the 120 asymptomatic subjects. Although recurrences of enzyme alterations involved 69.6% of patients, only in 30.1% of cases did a change of the underlying antiretroviral or antimicrobial therapy become necessary. An acute, uncomplicated pancreatitis occurred in nine of the 46 symptomatic subjects (19.6%). A two to four week gabexate and/or octreotide administration (performed in 79 cases of 166, 47.6%), achieved a significant laboratory, clinical and imaging cure or improvement in 82.3% of cases, with a better success rate of combined (gabexate mesilate plus octreotide) vs. single (gabexate mesilate or ocreotide) therapy. Reduced disease recurrences and a better tolerability of antiretroviral regimens, were also noticed.

Abstract
Acquired immune deficiency syndrome increases the risk of developing non-Hodgkin's B-cell lymphoma (NHL) (relative risk over 100). NHL tend to be high-grade and to affect the central nervous system and digestive tract. Biliary tract compression is usually due to external compression from enlarged lymph nodes, but is not usually the first manifestation.We describe 2 cases of bile duct obstruction secondary to NHL in patients diagnosed with HIV infection. Histological diagnosis of the lymphoma can be difficult but is necessary so that these patients do not undergo highly aggressive surgical treatment instead of chemotherapy, which currently produces the best results. Therefore, we emphasize the importance of including lymphomas in the differential diagnosis of bile duct obstruction in patients with HIV infection.

Abstract
In this article, the radiological manifestations of a variety of uncommon tumors of the pancreas are illustrated, with emphasis placed on their appearance at helical CT. Islet cell tumors, because of their vascularity, typically present as masses that are hyperattenuating to the normal pancreas at dual-phase helical CT. Lymphomas appear as hypoattenuating focal lesions or can diffusely infiltrate the gland. Absence of biliary tree dilatation, despite the presence of a bulky tumor, or associated extensive retroperitoneal adenopathy should offer clues to the diagnosis. Pancreatic metastases are usually seen in patients with advanced cancers, although isolated metastases from renal cell carcinoma can occurs years after the original tumor; such patients may benefit from surgical resection. Finally, the appearance of some rare neoplasms of mesenchymal origin is discussed.

Abstract
HIV cholangiopathy is a disease of advanced-stage AIDS that presents with biliary symptoms and anicteric cholestasis. An abnormal ultrasound examination in a patient with low CD4 count is evaluated by endoscopic retrograde cholangiopancreatography, which demonstrates the characteristic cholangiographic abnormalities. Besides being the gold standard for diagnosis, it offers therapeutic intervention and possible pain relief in the presence of papillary stenosis. An infectious pathogen is identifiable in a majority of patients, suggesting infection-related damage to the biliary tree. Anti-infective therapy, however, usually is ineffective, and prognosis is related to the underlying stage of AIDS.

Abstract
BACKGROUND Nutrients malabsorption frequently occurs in human immunodeficiency virus (HIV)-infected patients, but very few studies have investigated exocrine pancreatic digestive capacity in these patients. We therefore evaluated the frequency of exocrine pancreatic impairment and its eventual relation with fat malabsorption in HIV-infected patients. METHODS Thirty-five HIV-infected patients (30 male, 5 female: mean age +/- standard deviation, 33.6 +/- 7.2 years) and 51 sex- and age-matched controls without gastroenterologic diseases were studied. In all subjects fecal elastase 1 (EL-1) was assayed, and fecal fat excretion was evaluated with the steatocrit test. RESULTS Nineteen of 35 (54%) HIV-infected patients showed subnormal EL-1 values, whereas all the controls had normal values; furthermore, EL-1 values were significantly lower in patients than in controls: mean (95% confidence intervals), 207 ( 164-251 ) microg/g versus 312 (291-332) microg/g (P < 0.0001). Increased fecal fat excretion was observed in almost all (25 of 35) HIV-infected patients, and an inverse but not significant correlation was found between fecal EL-1 and steatocrit values. No association was found between reduced fecal EL-1 and the severity of HIV disease or nutritional and immunologic status. Opportunistic infections and drug administration had no influence on EL-1 concentrations in stools. CONCLUSIONS Reduced exopancreatic function is frequent in HIV-infected patients but does not seem to be a major factor contributing to fat malabsorption.

Abstract
Acute pancreatitis is a clinical condition that develops when active pancreatic inflammation is induced by stimuli noxious to the pancreas. Patients infected with human immunodeficiency virus (HIV) often have histologic abnormalities of the pancreas, and acute pancreatitis is much more common in HIV-infected patients than in the general population. This article reviews the epidemiology and etiology of acute pancreatitis in HIV-infected patients. The clinical presentation and treatment of acute pancreatitis in HIV-infected patients are also reviewed.

Abstract
Acute cholecystitis in a patient with HIV infection represents a difficult diagnostic problem. With improved antiretroviral therapy, many of the biliary problems we have seen in these patients are identical to those in nonimmunosuppressed patients (ie, they are largely caused by gallstones). The indication for cholecystectomy is usually right upper quadrant abdominal pain that has been persistent for weeks to months. Although cholecystectomy will result in pain relief in many patients, the presence of coexisting HIV cholangiopathy in about half these patients increases the likelihood of ongoing symptoms. Patients should be counseled that postoperative endoscopic retrograde cholangiopancreatography (ERCP) may be necessary and that some of the variants of HIV cholangiopathy do not respond to endoscopic therapy. The high perioperative mortality in these patients is not related to biliary tract disease but is rather a manifestation of severe underlying disease associated with advanced HIV infection. HIV cholangiopathy represents a complication of severe immunosuppression. Patients are generally in poor condition and often have coexisting infections or malignancies. The decision regarding how aggressively to approach a patient with suspected HIV cholangiopathy, a nonfatal condition, is best made with consideration of the degree of pain being reported. All patients should undergo an abdominal ultrasound, with ERCP being offered to those with severe or debilitating pain and who are found to have dilated bile ducts suggesting papillary stenosis. Should this finding be confirmed at cholangiography, sphincterotomy is effective palliation for abdominal pain in most cases. ERCP is considerably less useful in patients who have elevated liver enzyme levels without symptoms; there is only a small likelihood of identifying an infection not previously recognized or better diagnosed noninvasively. These patients do not generally benefit from sphincterotomy. The regular use of ERCP in patients with HIV for the evaluation of elevated liver enzyme levels is to be discouraged, because the very limited potential benefit of the procedure does not outweigh the risks.

Abstract
In the first part of our review, we discussed the general evaluation and clinical presentation of the various hepatic infections occurring in patients with AIDS. In addition, we focused on specific hepatic parenchymal infections. In this article, we will discuss the major clinical syndromes arising from opportunistic infections affecting the gallbladder (acalculous cholecystitis), biliary tree (AIDS-cholangiopathy), and pancreas (pancreatitis). Acalculous cholecystitis can develop in patients with AIDS who have not experienced the severe precipitating physiologic stresses normally required in patients without AIDS. The most common presentation is with right upper quadrant (RUQ) pain and tenderness. The diagnosis is a clinical one since there is no standard test, other than surgery. Cholecystectomy is the treatment of choice. The most common AIDS-associated infective complication of the biliary tree is AIDS-cholangiopathy. This is best viewed as a form of secondary sclerosing cholangitis resulting from a variety of opportunistic infections within the biliary tree. Affected persons present with RUQ pain and have marked elevations in the canalicular enzymes, alkaline phosphatase, and gamma-glutamyl transferase. Morphologic abnormalities are identified by endoscopic retrograde cholangiopancreatography. These include stricturing, dilatation, and beading of the biliary tract. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. Opportunistic infections within the pancreas gland have been documented in both pre- and postmortem studies. However, the true incidence of pancreatitis related to infections is unknown. The presentation is similar to that of pancreatitis from other causes. A computerized tomogram of the abdomen is the investigation of choice. Tissue aspiration or biopsy of the pancreas is required to demonstrate the presence of an opportunistic infection. The management is usually supportive, as it is rare that a specific infection is identified and treated.

Abstract
The liver, spleen, biliary tract, pancreas, and kidneys are commonly affected by opportunistic infection, malignancy, and inflammatory disorders during the course of human immunodeficiency virus (HIV) infection. Clinical manifestations of solid abdominal visceral involvement are protean and usually nonspecific, but it is important to establish a specific diagnosis promptly in these often critically ill patients. This presentation reviews the cross-sectional imaging spectrum of HIV-associated lesions of these organs.
