Laparoscopic Approach of Primary Hydatid Cyst of the Pancreas - Case Report and Literature Review.

The pancreatic localization of the hydatid cyst is exceptional, even in countries where hydatid disease is considered endemic. We describe a female patient, 63 years old, with hydatid cyst of the pancreas. The diagnosis was difficult because the presentation was that of an epigastric cyst of unknown origin, with no suggestive radiological and ultrasonography features. We performed a laparoscopic exploration of abdominal cavity which revealed a retrogastric cystic mass developed from the pancreatic body. The surgical treatment consisted in puncture, evacuation of proligera, lavage with hypertonic serum, partial excision of the pericyst and drainage of the cavity. The postoperative course was uneventfull and the patient was released after 5 days. The follow-up at 6, 12 and 24 month did not show relapse. Through this observation and a review of the literature, we discuss the diagnostic and therapeutic difficulties of this rare localization of the hydatid cyst. Hydatid cyst is a rare cause of a cystic lesion of the pancreas, especially in endemic areas. Surgery still remains the most effective treatment option. Laparoscopic approach is feasible and secure but requires a trained team with experience in minimally invasive surgery.

Clonorchiasis in Patients with Biliary and Pancreatic Diseases: Diagnosis and Risk Factors.

BACKGROUND: Many epidemiological studies have investigated the risk factors for clonorchiasis, but endoscopic findings of this disease in endoscopic retrograde cholangiopancreatography (ERCP) have not been well characterized. In this study, we evaluated clonorchiasis in ERCP in patients with biliary and pancreatic diseases. METHODS: This was a retrospective two-center study in hospitalized patients who received ERCP between January 2012 and October 2018. All patients were divided into clonorchiasis and nonclonorchiasis groups. Data were analyzed using univariate analysis and multivariate analyses. RESULTS: A total of 1119 patients were included, and clonorchiasis was diagnosed in 19.2% patients. Detection of Clonorchis sinensis eggs in bile samples was higher than that in fecal samples (85.9% vs. 58.7%; P = 0.001). In multivariate analysis, male patients (95% confidence interval (CI): 1.945-4.249, P = 0.001). In multivariate analysis, male patients (95% confidence interval (CI): 1.945-4.249, P = 0.001). In multivariate analysis, male patients (95% confidence interval (CI): 1.945-4.249, P = 0.001). In multivariate analysis, male patients (95% confidence interval (CI): 1.945-4.249, P = 0.001). In multivariate analysis, male patients (95% confidence interval (CI): 1.945-4.249, P = 0.001). In multivariate analysis, male patients (95% confidence interval (CI): 1.945-4.249. CONCLUSIONS: The detection of C. sinensis eggs was significantly higher in bile than in fecal samples; thus, bile samples represent a preferable sample for the diagnosis of clonorchiasis in patients with biliary obstruction. We found that male, age ≤ 60 years old, and CBD diameter < 12 mm were independent risk factors for clonorchiasis, while papilla fistula was a protective factor.C. sinensis eggs was significantly higher in bile than in fecal samples; thus, bile samples represent a preferable sample for the diagnosis of clonorchiasis in patients with biliary obstruction.

A case of human pancreatic eurytremiasis.

This study provides the first comprehensive imaging report of human pancreatic eurytremiasis. A 43-year-old man with obstructive jaundice and a pancreatic tumor was referred for diagnosis and treatment. Serum aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transpeptidase were elevated. Computed tomography (CT) revealed a multilocular cystic lesion with delayed enhanced area in the pancreas head. On magnetic resonance imaging, the tumor was hyperintense on diffusion-weighted image, and the apparent diffusion coefficient value of the tumor was lower than that of the normal pancreatic parenchyma. Positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro-D-glucose integrated with computed tomography (18F-FDG PET/CT) revealed abnormally increased uptake of 18F-FDG in the tumor. A subtotal stomach-preserving pancreaticoduodenectomy was performed on the preoperative diagnosis of pancreatic carcinoma accompanied by branch duct-type intraductal papillary mucinous neoplasm. Multifocal granulomatous lesions with necrotic areas including many parasite eggs were seen on the histology. The final diagnosis was pancreatic eurytremiasis.

Primary hydatid cyst of the pancreas of the child: a case report.

Primary pancreatic hydatid lesions are very rare with an incidence of less than 1% in the adult population. We report an observation of a 5-year-old girl who consulted for isolated abdominal pain occurring for 2 weeks without vomiting, transit disorders or jaundice and evolving in a context of conservation of the general condition and apyrexia. Clinical examination and preoperative imaging have suggested the diagnosis of a choledochal cyst or duodenal duplication rather than a hydatid cyst of the pancreas due to the presence of a cystic hepatic image projecting into the liver hilum. During the procedure, a hydatid cyst was found occupying the head of the pancreas. Primary hydatidosis of the pancreas in children is extremely rare. Possible sources of infection include: blood diffusion, local spread via biliopancreatic ducts and peripancreatic lymphatic invasion. In the endemic areas, hydatid disease should be mentioned in the list of differential diagnoses of cystic lesions located around the biliopancreatic junction in children.

[Unusual location of multiple hydatidosis, pancreatic and pelvic: about a case]. / Hydatidose multiple à localisation inhabituelle, pancréatique et pelvienne : à propos d'un cas.

Hydatid cyst is an infectious disease which is quite frequent in Morocco. Pelvic and pancreatic locations of this parasitic infection are rare, namely exceptional. We report the case of a 66-year old patient who was operated for liver hydatic cyst 6 years before, presenting for chest pain associated with hydatidoptysis. Chest X-ray objectified left hydropneumothorax. Thoraco-abdominopelvic CT showed mediastinal liquid mass as well as multiple hepatic, pancreatic (isthmus), pelvic and left under diaphragmatic cystic lesions. Hydatid serology was positive. Treatment involved thoracotomy associated with medical treatment.

Child with Pancreatic Hydatid Cyst Presenting with Cholestasis.

Although hydatid cysts are often seen in the liver and lungs, they may be present in many organs. Even in countries where hydatid cyst disease is endemic, the occurrence of pancreatic hydatid cysts is rare. Pancreatic hydatid cysts are important for the differential diagnosis of patients with pancreatic pseudocysts and cystic carcinomas. We could not find cystic echinococcosis cases which are kept together pancreas and liver in PubMed. In this article, we highlight the fact that pancreatic cystic echinococcosis may play a role in the etiology of cholestasis and that cysts may not be isolated in the pancreas in a pediatric population.

Oxidative stress associated with pathological changes in the pancreas of cattle naturally infected by Eurytrema coelomaticum.

Although Eurytrema coelomaticum is considered a parasite with low pathogenicity, it may be associated with mortality and loss of productive performance in animals due to chronic pancreatitis. The aim of this study was to evaluate the occurrence of oxidative stress caused by E. coelomaticum in naturally infected cattle, correlating the biochemical findings with the parasite load and histopathological changes. For this study, blood and pancreas samples from 51 cattle were collected, and levels of the thiobarbituric acid reactive substances (TBARS), advanced oxidation protein products (AOPP) and ferric reducing ability of plasma (FRAP) were measured in the serum and pancreas, and superoxide dismutase (SOD) activity was measured in total blood. Parasite burden was determined opening the pancreatic ducts, and then fragments of pancreas were collected and fixed in 10% buffered formalin and routinely processed for histopathology. From the 51 collected pancreas, 33 (63.5%) were parasitized. The average parasite burden per pancreas was 532 (12-2,578). TBARS and FRAP showed higher levels in serum and pancreas of infected animals (p<0.05), with a positive correlation between the histopathological changes and the number of parasites. SOD level in blood was 42% higher in parasitized group compared with control group (p<0.05), as well as AOPP in serum. Based on these results, we concluded that in natural infection by E. coelomaticum in cattle, oxidative stress occurs, characterized by the occurrence of protein oxidation, lipid peroxidation and activation of antioxidant system.

Isolated hydatid cyst of the pancreas masquerading as pancreatic pseudocyst.

Hydatid cyst of the pancreas is very rare and usually presents with obstructive jaundice. We report a case of a 7-year-old girl with cyst of the pancreas without any obstructive jaundice. The child was treated surgically and hydatid cyst of pancreas was found. Partial pericystectomy was performed. After 1 month on follow-up, the child developed pseudocyst of pancreas, which needed cystogastrostomy. Postoperatively, the child improved and is remaining well after 3 months of follow-up. Hydatid cysts of pancreas are very difficult to diagnose preoperatively and should be kept as a differential diagnosis of cystic intrapancreatic lesions. Serological tests can help in early diagnosis.

Pancreatic paragonimiasis mimics pancreatic cystic-solid tumor--A case report.

Paragonimiasis is frequently misdiagnosed owing to its various and complicated clinical manifestations. Although paragonimiasis has diverse manifestations, there is no report of paragonimiasis involving the pancreas. Herein we report the first case of pancreatic paragonimiasis, which was misdiagnosed as pancreatic cystic-solid tumor by CT scan. The pancreatic lesion was finally proved to be pancreatic paragonimiasis by pathological examination and serum antibody detection. The clinical manifestations and imaging features of this patient were analyzed. Pancreatic paragonimiasis should be an important differential diagnosis for pancreatic cyst-solid lesions.

Incidental isolated pancreatic hydatid cyst.

Isolated pancreatic hydatid cysts are a rare parasitic disease even in endemic areas. It is difficult to discriminate primary pancreatic hydatid cysts from other cystic and solid lesions of the pancreas. This is a case report of an incidental isolated pancreatic hydatid cyst. A heterogeneous cystic lesion in the body of the pancreas was identified on magnetic resonance imaging of a patient previously diagnosed patient with cholelithiasis, and because of the malignant possibility of the lesion, splenectomy with distal pancreatectomy and cholecystectomy was performed. The histopathologic diagnosis was reported as a hydatid cyst. Pancreatic hydatid cysts should be kept in mind in the differential diagnosis of pancreatic pseudocysts and cystic malignancies.

Hydatid cyst of the pancreas mimicking neoplasm.

Hydatid disease is a cyclozoonotic infection caused by the cestode genus Echinococcus. It occurs throughout the world and is especially common in sheep- and cattle-raising regions of Africa, Australia, New Zealand, India, the Middle East, South America, and the Mediterranean. The incidence of humans infected with hydatid disease is approximately 1-2:1000. It is higher in rural areas. Infection occurs via ingestion of infected meat. Hydatidosis is caused by sheep and cattle ingesting tapeworm eggs in dog feces. These eggs hatch in the duodenum and invade the liver, lungs, or bones of sheep and cattle. Humans are infected by ingesting the infected meat from these animals. In the organs, the embryo transforms into a cyst, which develops the germinal epithelium that produces capsules, larval forms, and eventually the infectious scolices. Although hydatid cyst of the pancreas is rare, it must be considered in the differential diagnosis of pancreatic lesions. We present a rare case.

Unusual sites for primary hydatid cysts: self experience with five cases.

Hydatid disease is a zoonotic disease caused by the tapeworm Echinococcus granulosus. It is common in the sheep-raising countries including Iraq. The usual site for involvement is the liver, followed by the lungs. Other sites may be affected less commonly and require a high index of suspicion for diagnosis. We present our experience with five cases of unusual sites of primary hydatid cyst, including the pancreas, the abdominal wall, the spleen, the back and the thigh. Three patients were females and two patients were males; their ages were between 15 and 39 years. All the patients were operated at our centre, and after a period of follow-up ranging between 2 and 6 years, there was no reported recurrence in any of the patients, neither at the primary site nor at other sites.

Percutaneous treatment of a primary pancreatic hydatid cyst using a catheterization technique.

Primary pancreatic hydatid cysts are rare and its percutaneous treatment and catheterization technique has, to the best of our knowledge, not been published in literature. A 33-year-old male patient who presented with abdominal pain was evaluated by ultrasonography (US) and computed tomography examinations. Both examinations revealed a cyst in the neck of the pancreas. After the administration of albendazole chemoprophylaxis, the patient underwent diagnostic puncture showing high pressure spring water which harbored the scoleces and was treated percutaneously by the catheterization technique. In this technique, first the cyst was punctured, the fluid content aspirated, the radiocontrast material injected to see possible fistulisation, and then re-aspirated. The 20% hypertonic saline solution was injected and re-aspiration was performed to the best of our abilities, followed by the insertion of a catheter for drainage of the remaining non-aspiratable fluid content. At follow-up examination, the cyst was not visible on US after 6 months. There was no evidence of cyst recurrence or dissemination after 18 months at serologic and imaging follow-up.
