title: [Intraductal papillary mucinous neoplasms of the pancreas in Hospital Nacional Guillermo Almenara Irigoyen, Lima, Peru].
abstract: OBJECTIVE
  To analyze retrospectively the clinical, radiologic and pathologic features as well as the surgical results of the patients with diagnosis of intraductal papillary mucinous neoplasms of the pancreas (IPMN).
  
  
  METHODS
  Patients with diagnosis of IPMN who underwent pancreatectomy were identified from January 2006 to September 2013, using the prospective data base of the Pancreas, Spleen and retroperitoneum HNGAI service.
  
  
  RESULTS
  A total of 11 patients were found (9 females and 2 males). The mean age was 67.36 years. 2 were main duct type IPMN, 3 branch type and 6 mixed type. All patients had symptoms. The pain was the most frequent symptom, 27% had pancreatitis. For the diagnosis 100% had CT scan, 90% MRI. 10 patients underwent pancreaticoduodenectomy and 1 distal pancreatectomy. 2 patients had type C pancreatic fistula. 2 patients underwent reoperation and 1 died. 5 patients had low grade dysplasia, 2 moderate dysplasia, 1 high grade dysplasia and 3 invasive carcinoma.
  
  
  CONCLUSIONS
  This entity is present in our country being more common in women. The mixed type IPMN is the most frequent type. Complication with the highest incidence is the pancreatic fistula and the mortality rate is low. The IPMN´s malignancy potential founded was high.
