[Primary hydatid cyst of the pancreas: Diagnosis and surgical procedures. Report of three cases]

Hydatid disease of pancreas: A case report

Primary pancreatic hydatid disease is extremely rare. Diagnosis of the disease is difficult because hydatid cysts can be confused with a pseudocyst or neoplastic cystic diseases. Authors report a case of a surgically treated hydatid disease of the uncinate process of pancreas. In a 34-year-old patient with minor symptoms, a cystic disease of the pancreas was accidentally identified. CT scan revealed a multivesicular cystic mass with a maximum of 13-cm diameter and with a calcificated wall. During laparotomy, the uncinate process of pancreas was resecated and the cystic lesion was enucleated. Patient was recovered without complications and recurrence of the disease. There must be a suspicion of hydatid disease when cysts are identified in good conditioned, asymptomatic patients, or in case of wall calcification or multivesicular cysts revealed by radiological images. Surgical procedures are recommended in uncertain diagnoses too, because differentiation preoperatively between cystic pancreatic lesions is often impossible.

Laparoscopic cystectomy for pancreatic echinococcosis: A case report and literature review

Cystic echinococcosis (CE) is a widely endemic helminthic disease caused by infection with the Echinococcus granulosus tapeworm. Following ingestion of eggs, hydatid cysts develop, most frequently in the liver and lungs, but occasionally in other organs. Infection of the pancreas by hydatid cysts is very rare, even in endemic areas. Most cases of pancreatic hydatid cysts reported in the literature were treated surgically using traditional open laparotomy. There are only few case reports describing laparoscopic treatment for this disease. Herein, we report on an eighteen-year-old female patient who was referred to our institution with a hydated pancreatic tail cyst. After a course of treatment with Albendazole, we successfully performed laparoscopic splenic-sparing distal pancreatectomy to remove the cyst with an uneventful intra- and post-operative course.

Surgery of the pancreatic cystic echinococcosis: systematic review

The prevalence of pancreatic cystic echinococcosis (PCE) in the world is low ranging between 0.2% and 0.6%. The diagnosis of PCE is easy when it is associated to other location such as liver, it became difficult when PCE was isolated simulating other diagnosis such as pseudocyst, a choledochal cyst, serous or mucinous cystadenoma and cystadenocarcinoma. This systematic review aimed to provide evidence-based answer to the following questions: (I) what are the efficient tools to affirm the diagnosis of isolated PCE and (II) what are the best therapeutic strategy for the PCE? An electronic search was performed by two authors (W Dougaz, I Bouasker). Medline, Scopus, Embase, Web of Science, Google Scholar and Cochrane collaboration were consulted. The keywords used were "cyst", "echinococcosis", "hydatid cyst" and "pancreas". All abstracts were analyzed followed by extraction of the full text by the same two authors (W Dougaz, I Bouasker), all divergences were resolved by discussion with C Dziri. Recommendations were based on Oxford's classification: (I) what are the efficient tools to affirm the diagnosis of PCE? -ultrasound remains the cornerstone of diagnosis. Magnetic resonance imaging (MRI) reproduces the ultrasound defined features of CE better than computed tomography (CT). MRI with heavily T2-weighted series is preferable to CT. Pancreatic duct MRI should be promising to identify a fistula between PCE and pancreatic duct (level of evidence 3-recommendation B); (II) what are the best therapeutic strategy for the PCE? -surgery is the main treatment of PCE. Open approach is validated. The decision depends of the location of PCE: head versus body and/or tail of the pancreas (level of evidence 5-recommendation D): for the head of the pancreas, the tendency is toward conservative surgery. For body and/or tail of the pancreas, the tendency is toward radical surgery. Medical treatment (albendazole) should be prescribed 1 week before surgery and 2 months during postoperative period (level II evidence and grade C recommendation).

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]

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.

Echinococcal Cyst of the Pancreas with Cystopancreatic Duct Fistula Successfully Treated by Partial Cystectomy and Cystogastrostomy

The primary pancreatic hydatid (echinococcal) cyst is extremely rare with a reported incidence of <1%. Owing to its rareness and a considerable overlap of imaging features, a preoperative diagnosis is usually difficult. The dilemma in confirming this benign diagnosis has often questioned the extent of radical pancreatic resection. The involvement of pancreatic duct (cystopancreatic duct fistula) further complicates the management of such cystic lesions. In this report, we present a case of isolated hydatid cyst of the pancreatic body and tail communicating with the pancreatic duct. Cystogastrostomy preceded by partial cystectomy in the same setting has never been reported to date. The patient had an uneventful postoperative course and follow-up showed no evidence of cyst recurrence or dissemination. We consider this a safe surgical option in longstanding large cysts, especially if a cystopancreatic fistula is detected beforehand. The success of such a procedure however may rely on the size and thickness of the cyst wall to support this anastomosis.

A Rare Case of Isolated Cystic Hydatid of Thyroid Gland

Hydatid cysts are most frequently localized within the liver and lungs, although they can also be found in highly vascularized tissues such as the brain, muscle, heart, pancreas, adrenal, and thyroid glands.A 65-year-old female patient was admitted to our clinic with complaints of a progressively growing mass that was compressing the surrounding tissues and causing respiratory distress. The pathological result was obtained as cytic hydatid.In patients with diagnosed hydatid cysts in the liver, systemic evaluation is necessary to rule out involvement of other organs. Among patients presenting with growths located in the neck, primary hydatid cyst of the thyroid gland must be considered in endemic regions.

[Hydatid cyst of the pancreas revealed by acute pancreatitis: report of a case]

La localisation pancréatique du kyste hydatique est exceptionnelle, même dans les pays où la maladie hydatique sévit à l’état endémique. Nous rapportons une observation de kyste hydatique du pancréas révélée par une pancréatite aigue. Le diagnostic était porté sur les données du scanner abdominal qui objectivait une masse kystique de la queue du pancréas adhérente au hile splénique. Le traitement chirurgical avait consisté en une splénopancréatectomie gauche. A travers cette observation et une revue de la littérature, nous discutons les difficultés diagnostiques et thérapeutiques de cette localisation rare du kyste hydatique.

Primary pancreatic hydatid cyst: an unexpected differential diagnosis

Hydatid disease, caused by the cystic stage of Echinococcus granulosus, most commonly involves the liver (59-75%) and lung (27%), and rarely involves the kidney (3%), bone (1-4%) and brain (1-2%). Even rarer sites include the heart and spleen, and skeletal muscle, with virtually no site being immune. The pancreas is an exceedingly rare site for primary disease (without concomitant involvement of the liver or peritoneum), with less than 20 reported cases in the literature. This case report describes a 48-year-old woman presenting with a solitary cystic lesion arising from the neck of the pancreas, which was ultimately determined to be a hydatid cyst on histopathological examination. It also discusses the difficulties in preoperative and postoperative management and includes a review of the literature.

Pancreatic body hydatid cyst: A case report

•

Pancreatic hydatid cyst is rarely reported.

•

Due to its rarity and similarity with more common pancreatic cystic conditions, diagnosis of pancreatic may be a challenging.

•

Past history of travelling to endemic ares should raise suspiscion to the possibility of hydatid disease.

INTRODUCTION

Hydatid disease is a parasitic infestation caused by the cystic stage of Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lung. Pancreatic affection by hydatid cysts is very rare even in endemic areas.

PRESENTATION OF CASE

Our case is a 34-year-old male patient referred to our centre with a pancreatic body cyst diagnosed by abdominal CT scan. The patient gave 3 months history of epigastric pain. He also gave history of travelling to Saudi Arabia and China. His enzyme-linked immunoadsorbent assay (ELIZA) test for echinococcal antigens was positive. Surgical exploration revealed a 7 cm cyst in the body of the pancreas separable from the surroundings. Endocystectomy and deroofing of the cyst was done.

DISCUSSION

Due to its rarity and similarity with more common pancreatic cystic conditions, diagnosis of pancreatic hydatid cyst may be challenging. Abdmonial sonography and CT scan together with enzyme-linked immunoadsorbent assay (ELIZA) test for echinococcal antigens are helpful diagnostic tools. Therapeutic options include endocystectomy and deroofing, albendazol therapy with percutaneous drainage or laparoscopic excision of the cyst.

CONCLUSION

Even in non-endemic areas, past history of travelling abroad in patients with pancreatic cystic lesions should raise the suspicion of hydatid disease as a possible diagnosis.

Extra-hepatic intra-abdominal hydatid cyst: which characteristic, compared to the hepatic location?

Hydatid cysts are mostly located in the liver, followed by the lung. Primary and isolated extrahepatic intra-abdominal hydatid cysts (PIEHC) are rare and only a few sporadic series have been reported. This article aims to study the epidemiological, diagnostic difficulties and therapeutic principles of PIEHC. More over, it aims to make comparison between PIEHC and the liver location of the cyst concerning all these data. We report a retrospective study from January 1995 to September 2010 concerning 34 patients who underwent surgical removal of a PIEHC. The mean age was 46 years. Abdominal pain was the main symptom, and was found in 27 patients (79.4 %). Physical examination revealed an abdominal mass in 19 patients (55.9 %). In 6 patients (17.6 %) the PIEHC was incidental. Abdominal ultrasound and abdominal CT scan helped to highlight all cystic masses. The diagnosis was established preoperatively in 28 patients (84.8 %). Five patients (14.7 %) were operated with a diagnosis other than PIEHC. The diagnosis was made intraoperatively in one case (2.9 %). A laparotomy in 24 cases (70 %) was the surgical approach often used. Majority of the patients, 25 cases (73.5 %), received a conservative procedure. Only 3 patients (8.8 %) had recurrences and were reoperated. The diagnosis of PIEHC is often facilitated by means of modern imaging, however, serious diagnostic problem were found with a pancreatic location of the cyst. Complete surgical excision, when possible without major sacrifice, seems to be the best therapeutic option to reduce the risk of recurrence.

Acute pancreatitis due to pancreatic hydatid cyst: a case report and review of the literature

Hydatid disease is a major health problem worldwide. Primary hydatid disease of the pancreas is very rare and acute pancreatitis secondary to hydatid cyst has rarely been reported. We report the case of a 38-year-old man who presented acute pancreatitis. A diagnosis of hydatid cyst of the pancreas, measuring 10 cm, was established by abdominal computed tomography before surgery. The treatment consisted of a distal pancreatectomy. The postoperative period was uneventful. Additionally, a review of the literature regarding case reports of acute pancreatitis due to pancreatic hydatid cyst is presented.
