Diagnosing Gallbladder Cancer: Methods and Procedures
Introduction:
Gallbladder cancer, although relatively rare, can be a serious and challenging disease to diagnose. Early detection is crucial for effective treatment and improved outcomes. This article aims to provide an overview of the various methods and procedures employed in the diagnosis of gallbladder cancer.
Medical History and Physical Examination:
The initial step in diagnosing gallbladder cancer involves a comprehensive medical history review and physical examination. Your doctor will inquire about your symptoms, risk factors, and any relevant family history. During the physical examination, they may palpate the abdomen to check for any abnormalities, tenderness, or masses.
Imaging Tests:
Imaging tests play a pivotal role in identifying gallbladder abnormalities and determining the presence of cancer. These tests provide detailed visualizations of the gallbladder and surrounding structures. Common imaging techniques include:
a. Ultrasound (US): Ultrasound is often the first-line imaging modality for gallbladder cancer diagnosis. It uses sound waves to produce real-time images of the gallbladder, helping detect any masses, thickened walls, or other abnormalities.
b. Computed Tomography (CT) Scan: CT scans provide cross-sectional images of the abdomen, enabling doctors to assess the gallbladder and surrounding organs in more detail. This imaging technique can reveal the extent of cancer, potential spread to nearby structures, and presence of lymph node involvement.
c. Magnetic Resonance Imaging (MRI): MRI scans use powerful magnets and radio waves to create highly detailed images of the gallbladder. They are particularly useful in evaluating the biliary tree, liver, and nearby blood vessels, aiding in staging gallbladder cancer.
d. Positron Emission Tomography (PET) Scan: PET scans involve the injection of a small amount of radioactive glucose, which helps identify areas with increased metabolic activity. PET scans can help determine the spread of cancer beyond the gallbladder and aid in the staging process.
Blood Tests:
Blood tests may be conducted to assess various markers that can indicate the presence of gallbladder cancer. These markers include:
a. Liver Function Tests (LFTs): LFTs measure the levels of certain enzymes and proteins in the blood, providing insights into liver and biliary system function. Elevated levels of bilirubin or liver enzymes may suggest gallbladder cancer.
b. Tumor Markers: Tumor markers, such as carcinoembryonic antigen (CEA) and carbohydrate antigen 19–9 (CA 19–9), are substances that may be elevated in the blood when cancer is present. While these markers are not specific to gallbladder cancer, they can be used in combination with other diagnostic methods.
Biopsy and Pathology:
A definitive diagnosis of gallbladder cancer often requires a biopsy, which involves the removal of a small sample of tissue from the suspicious area for microscopic examination. Biopsies can be obtained through various methods, including:
a. Fine-Needle Aspiration (FNA): In FNA, a thin needle is inserted into the gallbladder under imaging guidance to extract a small tissue sample for analysis.
b. Endoscopic Retrograde Cholangiopancreatography (ERCP): ERCP combines endoscopy with X-ray imaging to examine the biliary system. During this procedure, a small brush or forceps can be used to collect tissue samples from suspicious areas.
c. Surgical Biopsy: In some cases, when imaging and non-surgical biopsies do not provide a conclusive diagnosis, a surgical procedure such as laparoscopy or open surgery may be necessary to obtain a larger tissue sample for analysis.
Conclusion:
Diagnosing gallbladder cancer involves a comprehensive approach, combining medical history evaluation, physical examination, imaging tests, blood tests, and, if needed, a biopsy for pathological analysis. Early detection of gallbladder cancer is challenging due to its often asymptomatic nature in the early stages. However, advancements in imaging techniques and the utilization of tumor markers have improved the accuracy and reliability of diagnosis.
It is essential to consult with a healthcare professional if you experience symptoms such as abdominal pain, jaundice, unexplained weight loss, or digestive issues. Prompt diagnosis and early intervention can significantly improve treatment outcomes and increase the chances of successful management.

Lupine Publishers| IgG4-Related Disease Misdiagnosed as Cholangiocarcinoma
Abstract
Immunoglobulin G4-related disease (IgG4-RD) is an increasingly recognized immune-mediated condition comprised of a collection of disorders that share particular pathologic, serologic, and clinical features [1,2]. These disorders were previously thought to be unrelated [3-5]. The commonly shared features include tumor-like swelling of involved organs, a lymphoplasmacytic infiltrate enriched in IgG4-positive plasma cells, and a variable degree of fibrosis that has a characteristic “storiform” pattern. In addition, elevated serum concentrations of IgG4 are found in 60 to 70 percent of patients with IgG4-RD.
IgG4-related sclerosing cholangitis (IgG4-SC) is a characteristic type of sclerosing cholangitis, with an unknown pathogenic mechanism. Patients with IgG4-SC display increased serum IgG4 levels [6] and dense infiltration of IgG4-positive plasma cells with extensive fibrosis in the bile duct wall [7]. Circular and symmetrical thickening of the bile duct wall is observed in the areas without stenosis that appear normal on cholangiography, as well as in the stenotic areas [8]. IgG4-SC has been recently recognized as an IgG4- related disease. IgG4-SC is frequently associated with autoimmune pancreatitis (AIP). IgG4-related dacryoadenitis/sialadenitis and IgG4-related retroperitoneal fibrosis are also occasionally observed in IgG4-SC [9-12]. However, some IgG4-SC cases do not involve other organs. IgG4-SC is most common in elderly men. Obstructive jaundice is frequently observed in IgG4-SC.
A number of diseases, such as, Cystic fibrosis, Chronic obstructive Choledocholithiasis, Biliary strictures (secondary to surgical trauma, chronic pancreatitis), Anastomotic strictures in liver graft, Neoplasms (benign, malignant, metastatic), Infections, hypertonic saline instillation in the bile ducts, Post-traumatic sclerosing cholangitis, Systemic vasculitis, Amyloidosis, Radiation injury, Sarcoidosis, Systemic mastocytosis, Hypereosinophilic syndrome, Hodgkin’s disease, may easily be confused with IgG4- related sclerosing cholangitis, or coexist in a patient [13]. In this case, report 57 years male patient presented with jaundice, fatigue, weight loss, oral moniliasis and right sided neck swelling. He was misdiagnosed as Cholangiocarcinoma.
Keywords: IgG4-Related disease; Cholangiocarcinoma; Neck swelling; Jaundice
Abbreviations: IgG4-RD: Immunoglobulin G4-Related Disease, AIP: Auto Immune Pancreatitis, MRCP: Magnetic Resonance Cholangio Pancreatography, CT: Computed Tomography, ERCP: Endoscopic Retrograde Cholangio Pancreatography, PSC: Primary Sclerosing Cholangitis
Introduction
IgG4-related disease is a newly recognized fibro inflammatory disorder. Tumefactive lesions, storiform fibrosis, IgG4-positive plasma cells infiltration and frequent but not always elevated serum IgG4 level characterize it [14]. IgG4-related sclerosing cholangitis (IgG4-SC) is the most common extra pancreatic manifestation of IgG4-related disease, and it has become the third distinct disease entity of sclerosing cholangitis [15]. The clinical and radiological abnormalities seen in IgG4-SC may resemble those seen in cholangiocarcinoma. IgG4-SC frequently keeps accompany with concurrent autoimmune pancreatitis (AIP). Only few cases were reported to be diagnosed with IgG4-SC in the absence of AIP, with a male preponderance [16].
Case Report
This is a 57 years old male patient, diabetic but not hypertensive, Presented with right submandibular swelling, epigastric fullness anorexia, jaundice, itching, fatigue, weight loss, oral moniliasis and Tea colored urine for 10 days, Laboratory tests showed normal white blood cell count, 5930/Ul, elevated serum bilirubin, total 6.3mg/dl (0.4 - 1.4), direct 4.1mg/dl (< 0.4), high alanine aminotransferase (ALT) 222 U/L (3-30) and high aspartate amino transferase (AST) 114 U/L (10-35). Under the tentative diagnosis of obstructive jaundice. He underwent abdominal ultrasonography and dilatation of bilateral intrahepatic bile ducts was noted. Magnetic resonance cholangiopancreatography (MRCP) was performed. A short segment of stenosis in both hepatic ducts with marked poststenotic dilatation was revealed. Then, he underwent triphasic abdominal computed tomography (CT), which showed small hilar hepatic mass with dilated intra hepatic biliary radicals.
PET/CT study showed hypermetabolic pancreatic body lesion, hypermetabolic porta-hepatic soft tissue thickening and metabolically active right sub-mandibular mass (Figure 1). Cholangiocarcinoma was highly suspected and internal drainage was done with two stents by Endoscopic retrograde cholangiopancreatography (ERCP) (Figure 2). Pancreatic body mass biopsy showed chronic pancreatitis and inflammatory pseudo tumor. The tumor markers were checked and showed CEA 2.75mg/ ml (<3.4) and AFP 6.2mg/ml (<8). The serum total bilirubin was declined to 1.86mg/dl after ERCP. Salivary gland excision biopsy was done which showed extensive fibrosis, macrophages and dens plasma cell infiltration, multinucleated giant cells of foreign body type and the plasma cell were positive for IgG4 monoclonal antibody with no evidence of malignancy. The IgG4-positive plasma cells account for 80 - 100 per high-power field despite normal total IgG and IgG4 serum level. The patient diagnosed as IgG4 related disease and received rituximab 1g twice with 2 weeks interval in addition to oral prednisolone 40mg/d which was tapered gradually with marked improvement clinically and laboratory.
Discussion
The IgG4-associated cholangitis (IAC) is one of the IgG4 associated sclerosing disease. In fact, the IgG4 associated sclerosing disease had been reported to involve many organs, causing IgG4 associated sclerosing pancreatitis, cholangitis, retroperitoneal fibrosis, sialadenitis, lymphadenopathy, thyroiditis, nephritis, pneumonia, prostatitis, and some inflammatory pseudotumors [17]. Overlapping of these IgG4 associated sclerosing diseases is common. They are characterized by an elevated serum IgG4, extensive IgG4-positive plasma cells and T-lymphocyte infiltration in the involved organs and well responded to steroid therapy. The pathogenesis of IgG4-associated sclerosing disease remains undetermined [18].
Diagnosis of IAC requires a high index of suspicion. The differential diagnoses include primary sclerosing cholangitis (PSC), cholangiocarcinoma, pancreatic cancer and benign traumatic biliary stricture. The cholangiographic appearance of IAC is not specific. The stricture of bile duct in IAC might be in lower end of common bile duct when combined with autoimmune pancreatitis (AIP). Some were multiple and may be in the intrahepatic or the hilar hepatic bile duct and very similar to that of Primary sclerosing cholangitis (PSC) [19-21]. When the stricture is solitary and had no other combined pancreatic disease, it will be difficult to differentiate from carcinoma. Our case had a stricture in hepatic duct and normal pancreas, which led to misdiagnosis of cholangiocarcinoma preoperatively.
The elevated serum IgG4 is a hallmark of IAC, but it is not diagnostic for the disease. Not all IAC cases have high serum IgG4 [22]. On the contrary, some cases of PSC and other diseases might have high serum IgG4. It is difficult to differentiate cholangiocarcinoma from IAC by present imaging studies [23]. Use of IgG4 immunostaining on cytology specimens is not recommended because the density of IgG4- positive cells in the tissue cannot be determined from these specimens. Mild tissue IgG4 immunostaining can occur in other diseases [24]. Therefore, endoscopic brush cytology could not help to make a diagnosis of IAC, but a malignant result of cytology could exclude IAC. Preoperative diagnosis is sometimes difficult, especially when serum IgG4 is not high. Histological examination of the surgical specimen is needed to make a final diagnosis in some rare cases. The optimal steroid treatment regimen of IAC is not defined. Most patients respond initially to steroids but relapse is not uncommon 17. In patients with IAC, careful observation for relapse of cholangitis or other possible IgG4 associated sclerosing diseases is mandatory both during and after withdrawal of the steroid therapy. Though surgery is not indicated in patients with IAC, surgery had been performed in a great proportion of patients for the difficulty in making a precise diagnosis preoperatively before.

Advances in Therapeutics of Celiac Diseas
Authored by Anantha Naik Nagappa*
Abstract
The celiac diseases are on the rise with an incidence of 1:100. The celiac disease is caused by the activation of an immune system to the gluten found in staple food like wheat, rye and barley. In this disease ninety percentage of the patients get remission of the disease, when the patients are fed with gluten free diet. However, ten percentages of the patients don't respond to gluten-free diet. These patients are classified Refractory Celiac Disease (RCD) and (Non-Refractory Celiac Disease) NRCD. Some of these patients were going to develop the cancer of the colon called as Enteropathy-Associated T-Cell Lymphoma (EATL). There is no treatment for RRCD, NRCD and EATL. The advances in the treatment for RCD, NRCD and EATL include new strategy using monoclonal antibiotics and other Biotherapeutics approaches. These advances are discussed in these reviews.
Keywords: Celiac disease; Gluten; Refractory Celiac Disease; Non-celiac Gluten Sensitivity
Introduction
Celiac diseases (CD) are induced by gluten and related proteins which are like to cause intestinal damage. The major intervention of CD is avoided of gluten rich diet, which usually results improvement in lesions. However, all CD patients don't respond to clinical or histological recovery such patients are called Non- responsive CD. They have continued symptoms of lethargy, abdominal pain and diarrhea. Investigation of NRCD in the literature indicates there are no definitive treatments or management of NRCD patients. However, an arbitrary period of 6-12 months gluten free diet has been suggested. However, the NRCD patients don't show any improvement in the severity of the histological improvement or clinical symptoms. Hence, it is very clear the CD patients don’t respond positively with a designated as NRCD. Practical management depends upon the cause of persistent symptoms. Other kind of CD called Refractory Celiac disease, which are distant Non response to GFD [1]. RCD is defined by symptomatic and persistent villous atrophy despite of strict GFD. It has further divided into Type 1and Type 2. The clinical monitory has revealed the 80% of the RCD patient’s posses the intra epithelia lymphocytes which are easily recognized in the intestinal mucosal (CD 103+, intracellular CD3+, CD4", CD8", surface CD3"). These have originated by monoclonal T-cell receptors gamma gamma-gene arrangements which are detectable PCR analysis of biopsy specimen of intestinal of CD patients. The presence of aberrant has been termed as Type-1 RCD, which is usually not present in type1 RCD. It is interesting to know that the RCD-II patients have the greater mortality than RCD I. The major cause of death is attributed to the development of enteropathy associated with Enteropathy-associated T- cell lymphoma (EATL). The EATL is known to be malignant and it is hypothesized the presence of RCD T-cell phenotype represent a cryptic T-cell lymphoma. Patients with NRCD and RCD are usually present with weight loss, malabsorption and diarrhea [2].
Epidemiology
Its prevalence worldwide fluctuates around 0.5-1% of the population. An increase in frequency has been reported in the last years, doubling its prevalence in the last 20 years. Environmental factors have been proposed to explain this phenomenon, such as increased wheat consumption and infections at the beginning of life, although the evidence is not yet conclusive. According to the 2010 national health survey, a prevalence of between 0.6 and 0.8% is estimated in Children. The wheat usage has increased due to introduction of new recipes like pizza, Burger and bakery products which is the main ingredient of above junk food is divide of fibers present in whole grain flour. The refined white flour containing more gluten and less fiber helps the deposition of gluten in the large intestine. If instead whole grain wheat flour is there then it will help by facilitating the bowl evacuation and also these fibers are metabolized by the bacteria to Prebiotics in all such mechanism helps in the maintains of large intestine health and minimizing the gluten toxicity [3,4].
The Role of Gluten
The gluten is present in cereals like white, barley and rye which are cultivated in the Mediterranean countries and North America. Among these wheat is most popular staple food. It is used for making breads like roti and chapatti. In India, wheat was introduced by USA who gave the wheat in times of major famine. The gluten is a protein which contains extensive glutamine and proline. Gluten is poorly digested in the small intestine. The undigested gluten gets lodged in the large intestine where it is deposited. The deposited gluten is partially digested by the bacteria's leading to formation of toxic substance which has gliadin. Gliadin is a peptide alcohol-soluble fraction. The complex metabolites enter the lamina propria of the large intestine. After passing the lamina propria they are recognized by immune surveillance as foreign antigens and thus initiate immune response. These peptides pass through the epithelial barrier of the intestine, possibly during intestinal infections or when there is an increase in intestinal permeability, and interact with antigen-presenting cells in the lamina propria. Undigested molecules of gliadin, such as a peptide from an a-gliadin fraction made up of 33 amino acids, are resistant to degradation by gastric, pancreatic, and intestinal brush-border membrane proteases in the human intestine and they remain in the intestinal lumen after gluten ingestion which constantly keeping the immune response [5]. See Figure 1 [6] and Table 1 [7] for proposed classifications of immunological reactions to wheat and gluten and common foodstuffs containing Gluten and Gluten free respectively.
Pathogenesis
A complex interplay between genetic, environmental and immunological factors plays a crucial role in the pathogenesis of CD. In the 1940s Dicke identified gluten as the environmental trigger of CD. Gluten is a heterogeneous protein whose toxic fractions are a mixture of alcohol-soluble proteins called gliadins, which are found in cereals such as wheat, barley, rye consumed in most countries [5]. Gut enzymes are not capable of digesting gliadin fractions. Large proline/glutamine peptides therefore accumulate in the small intestinal lumen and may lead to pathological innate and adaptive immune responses in genetically predisposed subjects. CD is serious autoimmune disorder that usually occurs in genetically predispose persons, in response to continued exposure gluten rich diet it is estimated to report 1 in 100 worldwide. Clinically it is difficult to diagnose because it affects the patients in diverse manner for example, there are more than 200 types of celiac disease which may either in manifest symptoms in digestive system or some other part of the body. It is also interesting to know the CD may also develop in children or adults. Unfortunately some of the patients are symptoms they may show up negative results but a positive intestinal biopsy. However, CD are at a risk of long term complication despite they have the symptoms or symptomless. Digestive tract symptoms in children's include abdominal bloating and pain, chronic diarrhea, vomiting, constipation, pale, foul-smelling, weight loss, fatigue, irritability and behavioral issues, dental enamel defects of the permanent teeth, delayed growth, short stature, failure to thrive, and Attention deficit hyperactivity disorder. In adults, celiac disease patients having the less digestive symptoms like in children's however it is observed that 1/3 of celiac patients may experience. The adult celiac patients suffer from the iron deficiency anemia have fatigue, bone or joint pain, osteoporosis or osteopenia (bone less), liver and biliary tract disorder (transsminitis, fatty liver, primary sclerosing cholangitis) depression or anxiety, peripheral neuropathy (tingling, numbness or pain in the hands and feet) irregular menstrual cycle, canker sores inside the oral cavity, dermatitis, herpitiformis (itchy skin rashes). As per the World gastroenterology the celiac disease are classified into Classical celiac disease and non classical celiac disease. The CCD patients have malabsorption, diarrhea, steatorrhea (pale foul fatty stoles) and weight loss and growth failure among children’s. A non classical CD the patients may have mild GIT symptoms without clear signs of malabsorption. They may show up the abdominal distention with pain and symptoms like iron deficiency of anemia, fatigue, peripheral neuropathy unexplained elevated liver enzymes, reduced bone mass with frequent fractures, and folic acid vitamin B12 deficiency. They may also show late monarchy and late menopause unexplained infertility. They have dental enamel defects and suffer from depression and anxiety with dermatitis. There are also some patients who remained asymptomatic are called as patients which silent celiac disease. They don't have any symptoms but suffer from villous atrophy in small intestine. There is a genetic connection observed in first degree relatives or CD patients [8-10]. See Table 2 [11] for autoimmune conditions associated with CD.
Enteropathy-Associated T-Cell Lymphoma (EATL)
The cancer of the small intestine develops in celiac patients usually at the age of sixty and above. The disease is usually associated with Enteropathy the hallmark of T-cell lymphoma. The patients show up symptoms of Enteropathy-associated T-cell lymphoma occurs in adults, with the incidence peaking in the sixth decade of life, and is usually at an advanced stage at diagnosis. Symptoms may include malaise, anorexia, weight loss, diarrhea, abdominal pain, and unexplained fever and night sweating. The symptoms indicate the sensitivity to gluten challenge when patients are fed on GFD. There will be an improvement in the patient condition indicating that the celiac disease which is presented responsive to the gluten sensitization. However, the disease has been gone further too Enteropathy- associated T-cell lymphoma (EATL). This condition is malignant in nature needs proper diagnosis and treatment with appropriate chemotherapy and radiation therapy. It is agreed Enteropathy- associated T-cell lymphoma is complication of celiac disease. This disease rise from the intraepithelial T-lymphocytes which go into transformation due to poor adherence to GFD, HLA-DQ2 homozygosity and late diagnosis of CD. The suspicion of EATL is lead to extensive diagnostic efforts with magnetic resonance entroclysis, positron emission tomography scan, and histological identifications lesion. The treatment high dose of chemotherapy followed by the surgical resection along with autologous stem cell transplantation. However, strict adherence to GFD can only be the best prevention of exhilaration of EATL.
Refractory Celiac Disease (RCD)
Refractory Celiac Disease is a form of CD that not responds histological to at least one year of a strict GFD. It is also observed it is also involved in patients who initially response of GFD but gradually become non response. RCD further classified into RCDI and RCDII. RCD I is characterized by persisting atrophy of the villous even when patient is on strict GFD. Phenotypically normal intraepithelial lymphocytes (IELS). Whereas, in RCD II a clonally expansion of abnormal intraepithelial lymphocytes lacking surface CD3, CD8 and T-cell receptor markers with expression of intracellular CD3. This condition frequently evolves into EATL is the most serious complications of CD [5,12].
Non-celiac Gluten Sensitivity (NCGS)
People with Non-celiac Gluten Sensitivity (NCGS) experience symptoms similar to CD. These symptoms get resolved when they are on strict GFD. It is suspected the triggering of systemic immune response is not only due to gluten but also other antigenic substances which are present in the wheat and other cereals. Apart from the gluten and other antigenic components there seems to partially undigested carbohydrates which can sensitize the CD symptoms. These patients who become responsive to gluten, wheat free diet may fail to respond due to acquired sensitivity to the undigested carbohydrate. There are new approaches and scientific endures to understand the distinct pathology, and identification of biomarkers along with development in therapeutic Non-celiac Gluten Sensitivity diseases [7].
Diagnosis
Due large variety of celiac disease exceeding two hundred. It is extremely difficult to diagnose the type of celiac disease. The Biopsy, serological tests and histopathological are the standard tests. The objective of diagnosis of CD is to estimate whether villous atrophy has begin or what extent villous atrophy has spread across. The histology aims at identifying any cancerous transformation is there. The serology is to assess the immune responsiveness of the celiac diseases [13].
Treatment
The treatment of the celiac disease logically seems to be the withdrawal of gluten, wheat and other food which the patients sensitive. The pathological consequience of the CD involves disturbed microbiota leading to severe deficiency of B complex vitamins folic acid, B12, fat-soluble vitamins, iron, and calcium, . Hence, it is a necessary to assess the nutrition status of the patients. All patients with celiac disease should undergo screening for osteoporosis, which has a high prevalence in this population. It become necessary to administer total parental nutrition as patient's intestine is unable to absorb the nutritional factors due to atrophy of the villous. The health care team should include a skilled dietitian who monitors the patient's nutritional status and dietary adherence on a regular basis. In children, ongoing evaluation includes monitoring of growth and development [3,5,8,14].
Conclusion
The celiac diseases which are non responding to gluten free diet is a disease for which no definitive treatment although these patients make ten percentage of celiac disease. They are important because these patients are different from the patients who are responding to gluten free diet. The responses for the gluten free diet are measured by histopathological evidence freedom symptoms of celiac disease and improvement in index of quality of life. The RCD, NRCD and EATL in which the atrophy of the villous paralysis the absorptive capacity of the small intestine. There are severe deficiency of nutritious factors which can lead to malnutrition and calcium deficiency leads to osteoporosis. As these patients are unable to absorb through oral route. It becomes important to build and sustain the nutritional status by total parental nutrition many CD patients are frequently admitted to orthopedic ward for treatment of fractures of bone. Hence, there is need for a skilled dietician. The EATL is a cancer of small intestine it is recommended with chemotherapy. The treatment high dose of chemotherapy followed by the surgical resection along with autologous stem cell transplantation.
