title: Drainage of pancreatic pseudocysts. The importance of cyst wall biopsy in the recent era.
abstract: OBJECTIVE
  While open internal drainage has been the standard treatment for pancreatic pseudocysts, less invasive techniques which pay little attention to cyst wall biopsy, are becoming popular. The aim of this study is to report on our experience in draining pancreatic pseudocysts and probe the necessity or otherwise of obtaining a wall biopsy at drainage.
  
  
  METHODS
  Operation theatre registry, operation log books and medical records at Aseer Central Hospital, Abha, Kingdom of Saudi Arabia, were reviewed to retrieve the clinical details of patients with pancreatic pseudocyst who required a drainage procedure in a 13 years period from August 1989 to November 2002.
  
  
  RESULTS
  Sixteen patients were identified. Cyst wall biopsy was obtained in 10 cases, in 8 of them the diagnosis was confirmed, while a true cyst was found in the remaining 2 excluding them from further analysis. In the remaining 14 cases (8 males, 6 females, mean age 38 years, range 4-60), pain was the main presenting feature. Open internal drainage was offered to 12 cases while one patient received external drainage under ultrasound guidance and the other received open external drainage. The type of operation was cystogastrostomy in 9 patients and cystojejunostomy in 3 patients. The recurrence rate after internal drainage was 16.7%, while after external drainage was 100%. There was no mortality in this series. A procedure-related complication occurred in 3 (21.4%) patients.
  
  
  CONCLUSIONS
  The mortality, morbidity and recurrence rates in this series are compared favorably with other reports. The final diagnosis of a presumed pancreatic pseudocyst should rest on the histopathologic examination of the cyst wall.
