Hidatidosis pancreática en una niña de 5 años / Pancreatic echinococcosis in a 5-year-old girl

La hidatidosis pancreática representa el 0,2-0,6 % de los casos, siendo la población pediátrica la de mayor riesgo. Las lesiones suelen localizarse en cabeza del páncreas (50-58 %); la localización en cuerpo y cola del páncreas se encuentra en el 24-34 % y el 19 %, respectivamente. Dada la posibilidad de complicaciones, suele realizarse tratamiento quirúrgico. Se sugiriere indicar albendazol antes y después del acto quirúrgico por los riesgos de ruptura y diseminación de los protoescólices. Se presenta el caso de una niña de 5 años de edad con dolor abdominal progresivo y lesión quística en páncreas compatible con hidatidosis en la ultrasonografía. En la tomografía computada se observa compresión de la vía biliar. La hemoaglutinación indirecta fue negativa. Presentó elevación de la bilirrubina total, con franco predominio de bilirrubina directa, y aumento de enzimas hepáticas. Se realizó laparotomía exploradora, colecistectomía y destechamiento del quiste. Evolucionó favorablemente, continuó con albendazol durante 3 meses luego de la cirugía.

Pancreatic echinococcosis accounts for 0.2­0.6% of cases, with the pediatric population being at a higher risk. Most commonly, pancreatic lesions occur in the head of the pancreas (50­58%); and in the body and tail in 24­34% and 19% of cases, respectively. Given the potential complications, surgery is usually performed. Albendazole is recommended before and after the surgery due to the risks for rupture and dissemination of protoscolices. Here we describe the case of a 5-year-old girl with progressive abdominal pain and cystic lesion in the pancreas compatible with echinococcosis in the ultrasound. The computed tomography showed bile duct compression. Indirect hemagglutination was negative. She had elevated total bilirubin, with a clear predominance of direct bilirubin, and high liver enzymes. Exploratory laparotomy, cholecystectomy, and unroofing of the cyst were performed. The patient had a favorable course and continued with albendazole for 3 months after the surgery.

Effect of pancreatic extracorporeal shock wave lithotripsy on chronic pancreatitis stones / 中华外科杂志

Objective: To analyze the therapeutic effect and safety of pancreatic extracorporeal shock wave lithotripsy(P-ESWL) for patients with chronic pancreatitis complicated by stones of the pancreatic duct and to investigate the influencing factors. Methods: A retrospective analysis was performed on clinical data from 81 patients with chronic pancreatitis complicated by pancreatic duct calculus treated with P-ESWL in the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Xi 'an Jiaotong University from July 2019 to May 2022. There were 55 males(67.9%) and 26 females(32.1%). The age was (47±15)years (range: 17 to 77 years). The maximum diameter(M(IQR)) of the stone was 11.64(7.60) mm, and the CT value of the stone was 869 (571) HU. There were 32 patients (39.5%) with a single pancreatic duct stone and 49 patients(60.5%) with multiple pancreatic duct stones. The effectiveness, remission rate of abdominal pain, and complications of P-ESWL were evaluated. Student's t test, Mann Whitney U test, χ2 test, or Fisher's exact test was used to compare the characteristics between the effective and ineffective groups of lithotripsy. The factors influencing the effect of lithotripsy were analyzed by univariate and multivariate logistic regression analysis. Results: Eighty-one patients with chronic pancreatitis were treated with P-ESWL 144 times, with an average of 1.78 (95%CI:1.60 to 1.96) times per person. Among them, 38 patients(46.9%) were treated with endoscopy. There were 64 cases(79.0%) with effective removal of pancreatic duct calculi and 17 cases(21.0%) with ineffective removal. Of the 61 patients with chronic pancreatitis accompanied by abdominal pain, 52 cases(85.2%) had pain relief after lithotripsy. After lithotripsy treatment, 45 patients(55.6%) developed skin ecchymosis, 23 patients(28.4%) had sinus bradycardia, 3 patients(3.7%) had acute pancreatitis, 1 patient(1.2%) had a stone lesion, and 1 patient(1.2%) had a hepatic hematoma. Univariate and multivariate logistic regression analysis showed that the factors affecting the efficacy of lithotripsy included the age of patient(OR=0.92, 95%CI: 0.86 to 0.97), the maximum diameter of the stone(OR=1.12,95%CI:1.02 to 1.24) and the CT value of the stone(OR=1.44, 95%CI: 1.17 to 1.86). Conclusions: P-ESWL is effective in the treatment of patients with chronic pancreatitis complicated by calculi of the main pancreatic duct.Factors affecting the efficacy of lithotripsy include patient's age, maximum stone diameter, and CT value of calculi.

Prediabetes and type 2 diabetes are independent risk factors for computed tomography-estimated nonalcoholic fatty pancreas disease

OBJECTIVES: Nonalcoholic fatty pancreas disease (NAFPD) is characterized by excessive fat deposition in the pancreas in the absence of alcohol consumption. In this study, we aimed to detect a possible relationship between adipose tissue accumulation, prediabetes and diabetes. METHODS: This cross-sectional and retrospective study included 110 patients. Three groups were classified as controls, patients with prediabetes and patients with type 2 diabetes. The abdominal computed tomography (CT) attenuation measurement results of the pancreas were evaluated independently by two experienced radiologists. CT measurements and biochemical parameters were compared between study groups. The relationship between continuous variables was assessed by using one-way ANOVA. To determine the changes in the dependent variable for the effects on study groups, the independent variable was adjusted using ANCOVA. A p-value less than 0.05 was considered statistically significant. RESULTS: The presence of prediabetes and type 2 diabetes was correlated with a decrease in the mean Hounsfield Unit (HU) value of the pancreas (p=0.002). Age was determined to be an independent risk factor and was correlated with NAFPD (p=0.0001). When compared to the controls (p=0.041), 71% of patients with prediabetes and 67% of patients with type 2 diabetes were observed to have an increased incidence of NAFPD. Decreased serum amylase was found to be correlated with the mean HU value of the pancreas (p=0.043). CONCLUSION: NAFPD was independently correlated with both prediabetes and type 2 diabetes adjusted for age (p=0.0001) in this study. Additionally, age was determined to be an independent risk factor and was correlated with NAFPD.

Pancreatic endosonographic findings and clinical correlation in Crohn's disease

OBJECTIVES: We aimed to evaluate the incidence of pancreatic alterations in Crohn's disease using endoscopic ultrasound (EUS) and to correlate the number of alterations with current clinical data. METHODS: Patients diagnosed with Crohn's disease (n=51) were examined using EUS, and 11 variables were analyzed. A control group consisted of patients with no history of pancreatic disease or Crohn's disease. Patients presenting with three or more alterations underwent magnetic resonance imaging (MRI). Pancreatic function was determined using a fecal elastase assay. RESULTS: Two of the 51 patients (3.9%) presented with four EUS alterations, 3 (5.9%) presented with three, 11 (21.5%) presented with two, and 13 (25.5%) presented with one; in the control group, only 16% presented with one EUS alteration (p<0.001). Parenchymal abnormalities accounted for 39 of the EUS findings, and ductal abnormalities accounted for 11. Pancreatic lesions were not detected by MRI. Low fecal elastase levels were observed in 4 patients, none of whom presented with significant pancreatic alterations after undergoing EUS. Ileal involvement was predictive of the number of EUS alterations. CONCLUSION: A higher incidence of pancreatic abnormalities was found in patients with Crohn's disease than in individuals in the control group. The majority of these abnormalities are related to parenchymal alterations. In this group of patients, future studies should be conducted to determine whether such morphological abnormalities could evolve to induce exocrine or endocrine pancreatic insufficiency and, if so, identify the risk factors and determine which patients should undergo EUS.

Factores de riesgo para páncreas hiperecogénico en ecoendoscopía: estudio de casos y controles / Risk factors for hipoerecogenic páncreas in ecoendoscopy: study of cases and controls

Objetivo: Identificar con ecoendoscopía (EE) páncreas hiperecogénico y determinar factores de riesgo para el mismo en una muestra de pacientes evaluados entre Junio 2005-Mayo 2010. Material y métodos: Estudio de casos y controles, retrospectivo, en una población de 5495 pacientes evaluados, de los cuales se seleccionaron 989 como casos (con un aumento de ecogenicidad parcial o global del páncreas) y 642 controles (con ecopatrón pancreático normal). Se compararon variables demográficas, clínicas y ecoendoscópicas entre ambos grupos de estudios y se calcularon OR y sus correspondiente IC95% después de realizar análisis bivariado y multivariado de los factores de riesgo. Resultados: En la población evaluada, los factores de riesgo identificados con mayor fuerza de asociación en el análisis multivariado fueron esteatosis hepática (OR=29,581; IC95% 17,942-48,770), hepatopatía mixta (OR=10,724; IC95% 1,634-70,378), hipotiroidismo (OR=8,381; IC95% 2,067-33,977) y tabaquismo (OR=2,790; IC95% 1,036-7,515). Otros factores asociados en menor magnitud fueron: hepatopatía crónica, antecedentes familiares de diabetes mellitus e hipertensión arterial, edad e índice de masa corporal. Conclusiones: Existen escasos estudios que hayan identificado factores de riesgo para esteatosis pancreática empleando EE. Los hallazgos encontrados concuerdan con lo reportado recientemente en otros estudios internacionales donde la esteatosis hepática fue el predictor de mayor fuerza para encontrar en la EE páncreas hiperecogénico (OR=29). Sin embargo, el presente estudio encontró una asociación dos veces mayor a la previamente reportada. En adición a ello se observa claramente que en el presente estudio existen múltiples factores asociados al hallazgo de páncreas hiperecogénico que deben ser tomados en cuenta.

Objective: To identify through ecoendoscopy (EE) hyperecogenic pancreas and to determinate risk factors for it in a sample of patients evaluated between June 2005 and May 2010. Material and methods: Cases and controls study, retrospective observational study, in a population of 5,495 patients; from them 989 were selected as cases (with an increase of partial or global ecogenicity of the pancreas) and 642 controls (with a normal pancreatic ecopattern). Demographical, clinical and ecoendoscopical variables from both groups were compared; OR were calculated with their 95%CI, after bivariate and multivariate risk factors analyses. Results: In the studied population, identified risk factors, mostly associated at the multivariate analyses, included: liver steatosis (OR=29.581; 95%CI 17.942-48.770), mixed hepatopathy (OR=10.724; 95%CI 1.63470.378), hypothyroidism (OR=8.381; 95%CI 2.067-33.977) and smoking (OR=2.790; 95%CI 1.036-7.515). Other factors were: chronic hepatopathy, family history of diabetes mellitus and high blood pressure, age and body mass index. Conclusions: There are few studies regard the identification of risk factors for pancreatic steatosis using EE. Current findings are similar with others recently reported in other countries, where liver steatosis is a predictor to find hyperecogenic pancreas at the EE (OR=29). However, this study found an association two-fold higher than that previously reported. In addition, is clear that in this study there are multiple factors associated with the finding of hyperecogenic pancreas that should be considered.

Histopathological changes of pancreas in patients with fibrocalculous pancreatopathy.

A total of 20 pancreatic biopsy samples taken from Fibrocalculous Pancreatopathy previously known as Fibro Calculus Pancreatic Diabetes (FCPD) patients, a variant of Malnutrition Related Diabetes Mellitus (MRDM) or under 30 young diabetes attending hepatobiliary, surgical and out patient department of Bangladesh Diabetes, Endocrine and Metabolic (BIRDEM) hospital were processed for light microscopic examination. Four samples were subjected to Immunohistochemistry (IHC) staining using antibodies to T cell marker (CD3), B cell marker (CD20), anti apoptotic markers (bcl-2) and tumour suppressor gene marker p53. Light microscopic findings and IHC indicate an immune mediated injury of pancreatic tissue and increased evidence of apoptosis which possibly results in the development of diabetes in these patients.

Non insulinoma pancreatogenous hypoglycemia syndrome in a Saudi male

Nesidioblastosis is focal or diffuse islet hyperplasia leading to hyperinsulinism with subsequent hypoglycemia in the absence of insulinoma, usually described in neonates and infancy. We described the first adult case of nesidioblastosis in Saudi Arabia and the Gulf region. The diagnosis and treatment of the condition can be very difficult and challenging. Despite the fact that our patient responded initially to surgical treatment, his hypoglycemic symptoms occasionally recurred and needed adjunctive medical treatment. Although initially thought to affect only infants and children, cases of nesidioblastosis can affect adults and pose a diagnostic and therapeutic challenge to the clinicians

Tuberculose pancreática: relato de caso e revisão da literatura / Pancreatic tuberculosis: a case report and literature review

O pâncreas é raramente afetado por infecções pelo bacilo Mycobacterium tuberculosis, provavelmente em função da presença das enzimas pancreáticas, e apenas alguns casos são descritos na literatura. O diagnóstico diferencial com carcinoma pancreático é um desafio em virtude das semelhanças clínico-radiológicas. Apresentamos um caso de um paciente de 39 anos de idade, do sexo masculino, com quadro clínico de perda ponderal, náuseas e vômitos. A propedêutica radiológica com tomografia computadorizada de abdome revelou lesões em cauda do pâncreas e baço. O diagnóstico foi confirmado por exame histopatológico após laparotomia.

The pancreas is rarely affected by Mycobacterium tuberculosis infections, probably because of the presence of pancreatic enzymes, and only few cases are reported. The differential diagnosis with pancreatic carcinoma represents a challenge because of clinical and radiological similarities. We report the case of a 39-year-old male patient presenting weight loss, nausea and vomiting. Radiological workup with abdominal computed tomography has demonstrated lesions in the pancreatic tail and spleen. The diagnosis was confirmed by histopathological analysis following laparotomy.

Obstructive jaundice: a manifestation of pancreatic tuberculosis.

Tuberculosis of the pancreas is extremely rare and is most often associated with miliary tuberculosis or occurs in the immunocompromised patients. A case of isolated pancreatic tuberculosis in an immunocompetent patient is presented with constitutional symptoms and obstructive jaundice. Ultrasonography and computerised tomography showed a mass lesion in the head of pancreas. Histological examination of the peripancreatic lymph node and fine needle aspiration cytology from the head of pancreas confirmed the diagnosis following laparotomy. Patient recovered following the administration of antituberculosis chemotherapy.

Pancreatic calculus impacted at Ampulla of Vater causing severe cholangitis and septic shock.

Patients with chronic pancreatitis may have varied complications including common bile duct stenosis, cholangitis, pseudocyst or fistula formation and secondary biliary cirrhosis. Common bile duct obstruction due to disimpaction of a pancreatic calculus into the ampulla of Vater leading to severe cholangitis and septic shock is a rare phenomenon. We are reporting such a case here.

Abdomen agudo en el adulto mayor / Acute abdomen in the elderly

Background: Nearly 10% of emergency consultations are due to acute abdominal pain. In people over 65 years old, it can have atypical presentations, that retard the correct diagnosis and worsens prognosis. Aim: To study the causes, evolution and prognosis of acute abdomen in the elderly. Material and methods: Prospective study of 45 patients aged more than 65 years old (mean age ± SD, 75.7±7.7, 51% men) and 221 patients of less than 65 years old (mean age ± SD, 36.7±14.0, 48% men), consulting for acute abdomen in the emergency room. Results: Sixty six percent of elderly patients had concomitant diseases, that were multiple in 63%. In this age group, the causes accounting for 71% of acute abdominal pain were bilio-pancreatic diseases (31.1%), intestinal adhesive obstruction (17.7%), complicated abdominal wall hernia (13.7%), and complications of peptic ulcer disease (8.9%). Sixty four percent required surgical treatment and, in almost 50% the surgical risk was classified in ASA III or IV, according to the American Society of Anesthesiology. Thirty one percent had postoperative complications. Compared with their younger counterparts, elderly patients required significantly (p<0.05) more admissions to intensive care units (2.7 and 24.2% respectively), more connections to mechanical ventilation (1.4 and 8.9% respectively) and longer hospital stays (5.4±7.4 and 12.4±10.9 days, respectively). In this series overall mortality was 6.7%, being 0.6% for young patients and 11.1% for the surgical group over 65 years old. Conclusions: Acute abdomen in the elderly has a high rate of complications and mortality. According to the causes of acute abdomen in this group, evaluation in the emergency setting with an ultrasonography may be very useful. In the elderly, elective correction of potential causes of acute abdomen should be done.

Isolated tuberculosis of the pancreas: a report of two cases and review of the literature.

We report two cases of pancreatic tuberculosis. The first patent (who tested positive for HIV) presented with abdominal pain, fever, weight loss, anorexia and tender epigastric lump. The CT scan revealed multiple small abscesses in the pancreas. The second patients, who had no evidence of immunodeficiency, presented with constitutional symptoms and obstructive jaundice. The CT scan revealed a mass in the pancreatic head with peripancreatic lymph nodes and dilatation of the intrahepatic and extrahepatic biliary tree. None of the patients had Mycobacterium tuberculosis infection of the lung or any other organ. Fine-needle aspiration biopsy clinched the diagnosis in both the patients, with caseation necrosis and plenty of acid-fast bacilli in the first patient, and characteristic granulomatous inflammation of the pancreas in the other. The first patient died during the index hospitalization, while the other responded well to antitubercular treatment with improvement in symptoms and radiological clearance of the initial lesions.

A Case of Serous Cystadenoma of the Pancreas Communicating with the Pancreatic Duct / 대한소화기학회지

Serous cystadenoma of the pancreas is a rare disease and is usually benign. Mucinous cystadenoma, another cystic neoplasm of the pancreas, has a malignant potential. Serous cystadenoma is usually composed of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. With the finding of endoscopic retrograde pancreatography, a communication between the cyst and pancreatic duct is observed occasionally in the mucinous cystadenoma, but rarely in the case of serous cystadenoma of the pancreas. We experienced a case of serous cystadenoma of the pancreas that had a communication between a cyst and the pancreatic duct.

The clinical spectrum of fibrocalculous pancreatic diabetes in north India.

BACKGROUND: Fibrocalculous pancreatic diabetes (FCPD) is a secondary form of diabetes, unique to tropical countries. In earlier reports, patients with FCPD had severe insulin-requiring diabetes, malnutrition and a dismal prognosis. With Improvements in nutrition and medical care, the presentation and prognosis of FCPD may have changed. We report on the clinical profile and prognosis of a cohort of FCPD patients from north India and compare our findings with earlier reports. METHODS: Eighty consecutive FCPD patients who presented to the Diabetes, Gastroenterology and Surgical Gastroenterology services were evaluated for their nutritional status, clinical presentation, beta-cell function (fasting C-peptide) and exocrine function (faecal chymotrypsin). All patients diagnosed between 1994 and 2000 (n = 32) were followed prospectively for weight gain and glycaemic control. RESULTS: Only 55% of FCPD patients had a low body mass index (< 18 kg/m2). At the time of diagnosis of diabetes, only 26 (33%) patients presented with severe insulin-requiring diabetes; these patients were younger [23.7 (8.3) years v. 28.7 (10.6) years, p = 0.04], and had higher haemoglobin A1c [9.7 (3.8)% v. 7.3 (2.6)%, p = 0.005] than those requiring diet control or oral hypoglycaemic agents. FCPD patients had a wide range of fasting serum C-peptide (0.03-0.76 nmol/L). C-peptide was negatively associated with increasing duration of diabetes (r = -0.48, p = 0.001), but there was no correlation with faecal chymotrypsin. On prospective follow up (mean 2.3 years), there was significant improvement in body mass index [19.4 (2.9) kg/m2 v. 17.0 (3.7) kg/m2, p < 0.01] and haemoglobin A,c [6.4 (1.6)% v. 8.0 (3.0)%, p < 0.001]. CONCLUSION: FCPD patients differed from those described in earlier reports in many respects, Including improved nutritional status, a wide range of 3cell function and a more favourable prognosis.

Nesidioblastosis / Nesidioblastosis

La nesidioblastosis es una causa conocida de hipoglicemia persistente en neonatos, pero las publicaciones acerca de su presencia en adultos son escasas. Se describe el caso de una mujer de 44 años de edad que se presentó con hipoglicemia grave asociada a hiperinsulinismo, en la cual no fue posible el diagnóstico de insulinoma mediante los métodos disponibles en el país ni durante la exploración quirúrgica, siendo sometida a una pancreatectomía corporocaudal. El examen histológico reveló la presencia de nesidioblastosis, dado el hallazgo de hiperplasia de células de los islotes provenientes del páncreas endocrino. El seguimiento demostró el control de la glicemia y actualmente la paciente se encuentra asistomática

Evaluation of various diagnostic signs on percutaneous transhepatic cholangiography in obstructive jaundice.

Twenty patients of obstructive jaundice were subjected to percutaneous transhepatic cholangiography (PTC) of which 17 were operated on. Patients were divided in 4 groups according to the site of obstruction. The diagnostic signs observed were: Complete block with interface having convexity downwards (4), convexity upwards (3), biconcave caudal cut off (6), smooth edged cut off (one), irregular edged cut off (one) and non-specific appearance (one); incomplete block with interface having convexity upwards (one); biconcave caudal cut off (2) and multiple smooth central filling defects (2). In one case there was incomplete obstruction at two sites giving rise to two different signs. PTC was 100% correct in accurately telling the site of lesion. As regards the nature of the lesion the diagnosis on PTC was found correct in 15 out of 17 cases (88.5%).

Persistent hyperinsulinemic hypoglycemia of infancy.

OBJECTIVE: To study the nature and clinical course of persistent hyperinsulinemic hypoglycemia of infancy (PHHI) due to nesidioblastosis. DESIGN: Clinical, laboratory and therapeutic evaluation of infants with this disorder and study the outcome. SETTING: Hospital born neonates and infants referred from other hospitals. SUBJECTS: Thirteen infants from 9 families inclusive of four pairs of siblings referred within few hours of birth to 3 months of age, for seizures. Mean birth weight was 3.68 +/- 0.45 kg. Consanguinity documented in one sporadic and one familial case. METHODS: Clinical and laboratory evaluation by standard biochemical and radioimmunoassay techniques. RESULTS: The mean serum insulin level of 24.2 +/- 12.5 mIU/ml was in the normal range but inappropriately high for the corresponding hypoglycemic blood sugar (23.1 +/- 9.1 mg/dl) value, with an I/G ratio of 1.36 +/- 0.97; as in hyperinsulinemia (normal < 0.4). Investigations excluded other causes of persistent hypoglycemia. A trial of i.v./oral glucose, frequent carbohydrate rich feeds in all, oral diazoxide (10 to 20 mg/kg) in 9/13 cases along with subcutaneous octreotide (20 micrograms/kg QID) in one helped, but pancreatic resection (85 to 90%) was opted for in two (1 familial, 1 sporadic). Six infants including one with pancreatic resection succumbed to hypoglycemia (n = 1) or fulminating infection (n = 3) or brain damage. Of the seven survivors, one familial case with pancreatic resection is brain damaged, and of the six on diazoxide therapy, one is slightly subnormal while one sporadic and three familial cases have done well. One infant was lost to follow up. Diazoxide could be withdrawn in two subjects (1 familial, 1 sporadic) by 8 years of age signifying maturation of islet cell function. CONCLUSION: PHHI appropriately known as 'Islet cell dysmaturation syndrome' is a complex disorder posing problems in diagnosis and therapy. The high familial incidence (77%), with intrafamilial variation in the severity, insulin levels in the normal range but in appropriately high for the blood glucose levels, normal C-peptide levels, with normal I/G ratio (< 0.4) in 4/13 are some of the notable features of this study. Severe recurrent infections in nearly 30%, is an unusual feature in this series and needs an indepth study. The mortality (46%) and morbidity (43%) in survivors is high and calls for greater awareness, early diagnosis and genetic counselling, as this disorder may be familial.
