Gastric duplication cyst communicating to accessory pancreatic lobe: A case report and review of the literature
Abstrakt
BACKGROUND The combination of a gastric duplication cyst and duplicated part of the pancreas is an extremely rare developmental defect. The incidence in the population, or the clinical impact thereof, has not been uncovered.
Symptoms are unspecific. Surgery is the treatment of choice.
Timely diagnostics are of utmost importance, albeit they might be challenging at times. Being so rare, case reports are currently the only relevant source of information about the condition.
Therefore each published finding is of a clinical impact. CASE SUMMARY Our work describes the case of a 22 year-old patient, who developed idiopathic acute pancreatitis.
A computed tomography scan discovered liquid collection between the antrum of the stomach and the head of the pancreas. Initially, the collection was thought to be a pancreatic pseudocyst.
Endoscopic ultrasound-guided transgastric drainage showed to have only a temporary therapeutic effect. Magnetic resonance cholangiopancreatography showed an accessory pancreatic lobe with a separate duct system.
The accessory pancreatic lobe exited the body of the pancreas and was in contact with the cystic collection. The patient was indicated for surgical resection.
Within the surgery, an en bloc resection of the accessory pancreatic lobe was performed with the antrum of the stomach containing the gastric duplication cyst. No complications were observed in the surgery or thereafter.
In the five months follow-up period, the patient was completely symptom free. Histopathological findings confirmed the gastric duplication cyst communicating to accessory pancreatic lobe.
CONCLUSION This developmental defect is extremely rare. It can cause recurrent acute pancreatitis.
Diagnostics are challenging. Surgery is treatment of choice.
