Insights
A rare pancreatic hydatid cyst caused acute cholangitis in a child. Surgical intervention and supportive care successfully managed the cyst and resulting pancreatic fistula.
Area of Science:
- Gastroenterology
- Parasitology
- Surgical Pathology
Background:
- Pancreatic hydatid cysts are rare, accounting for 0.1-1% of all hydatidoses.
- Hydatid disease is caused by the tapeworm Echinococcus granulosus.
Observation:
- A 12-year-old boy presented with acute cholangitis, cholestasis, cytolysis, and eosinophilia.
- Imaging revealed a large (100 mm) hydatid cyst in the pancreatic head, causing biliary and pancreatic duct dilation.
Findings:
- Exploratory laparotomy confirmed the pancreatic hydatid cyst and revealed a pancreatic fistula.
- Subtotal cyst excision and external pancreatic fistula drainage were performed.
- The pancreatic fistula resolved after two months with hypercaloric and hyperprotidic feeding.
Implications:
- This case highlights the importance of considering parasitic infections in pancreatic pathology.
- Effective management involves a multidisciplinary approach combining surgical and medical interventions.
- Early diagnosis and treatment are crucial for favorable outcomes in pancreatic hydatid cysts.
Abstract:
Pancreatic hydatid cysts represent 0.1 to 1% of all hydatidoses. A 12 year-old-boy, with a previous history of abdominal pain, was admitted for acute cholangitis. Laboratory investigations showed cholestasis, cytolysis and eosinophilia. Serum amylase levels were normal. Abdominal ultrasound and CT scan revealed a 100 mm hydatid cyst, located in the head of the pancreas. The biliary and pancreatic ducts were markedly dilated. Exploratory laparotomy confirmed the diagnosis. A pancreatic fistula was discovered. Subtotal excision of the cyst and external drainage of the pancreatic fistula were performed. Laboratory tests were normal post-operatively. The pancreatic fistulae persisted for two months. Hypercaloric and hyperprotidic feeding resulted in occlusion in three weeks. The rest of the postoperative course was uneventful and the size of the biliary and pancreatic ducts was normal. The authors discuss the diagnostic features of pancreatic hydatid cyst and discuss therapeutic modalities.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Acute Pancreatitis II: Clinical Manifestations and Management
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
