Primary hydatid cyst of the pancreas.

BACKGROUND: Hydatid cyst of the pancreas is rare, accounting for less than 1% of the various sites of hydatid disease, even in countries where echinococcosis is endemic. We report a case of pancreatic hydatid cyst to increase awareness for this important condition. CASE REPORT: We describe a 33-year-old male with abdominal discomfort of one-year duration. On abdominal examination, there was mild tenderness with fullness in the right upper quadrant. Laboratory investigations revealed no abnormalities. Abdominal ultrasonography showed a cystic mass over the head of the pancreas. Abdominal CT scan confirmed the presence of a solitary cyst in the pancreatic head, with no enhancement on contrast CT. Indirect hemagglutination test for hydatid disease was negative. A pre-operative diagnosis of cystic neoplasm of the pancreas was made and laparotomy was done; on exploration there was a cystic mass arising from the head of the pancreas. A pericystectomy was carried out and the diagnosis of hydatid cyst of the pancreas was confirmed by histopathology. The postoperative period was uneventful and no recurrence was seen after 2 years of follow-up. CONCLUSION: Pancreatic hydatidosis, though very rare, should be considered in the differential diagnosis of pancreatic cystic lesions in the appropriate epidaemiological setting.

Overview of extremity arterial trauma in Jordan.

AIM: The objectives of this study were to review etiologies of trauma, associated injuries, diagnosis, management, and outcomes of patients with vascular injuries in the extremities and relate factors in their treatment to the outcome of the injured extremity. METHODS: Data were collected retrospectively on 73 patients diagnosed to have upper and lower limbs arterial injuries at King Abdullah University Hospital, Jordan, between 2001 and 2006. Factors evaluated included demographic data, location of vessels injured, mechanism of injury, associated injuries, treatment, and outcome. RESULTS: Patients were predominantly males (54 patients). Isolated vascular trauma was present in 36 patients, while in the remaining 37 patients vascular trauma was aggravated by concomitant injuries. The most common etiology of vascular injuries in the upper and lower extremities was a penetrating injury found in 38 patients (52%). The vessels most commonly involved were the femoral and brachial arteries. Various associated injuries were identified mainly orthopedic in 21 patients (29%) and nerve injuries in 18 patients (25%). Autogenous vein graft interposition was mostly performed in 32 patients (44%). Permanent disability was seen in 8 patients (11%), limb amputation was performed in 5 patients (7%). Five patients died due to associated intraabdominal, thoracic, and head injuries giving a mortality rate of 7%. CONCLUSIONS: Delay in surgery, blunt trauma and extensive soft tissue defect in combined orthopedic and vascular injuries were associated with increased risk of amputation, while associated nerve injuries and bone injuries with extensive soft tissue damage are risk factors of poor quality outcome.
