AB  - Pseudocysts  of  the  pancreas  are  not  an  uncommon  sequela  of  acute  pancreatitis,  chronic  pancreatitis,  and  blunt  abdominal  trauma  with  resulting  traumatic  pancreatitis.  Pancreatic  pseudocysts  should  be  suspected  when  symptoms  remain  after  the  initial  episode  of  pancreatitis  has  resolved.  A  palpable  mass  may  be  detected  in  the  upper  abdomen,  most  frequently  in  the  midepigastrium  or  the  left  upper  quadrant.  These  cysts  do  not  have  an  epithelial  lining,  as  do  true  pancreatic  cysts.  Pancreatic  pseudocysts  are  found  most  commonly  in  the  body  and  tail  of  the  pancreas  but  also  may  be  found  in  the  neck  and  head  of  the  pancreas.  Ultrasonography,  computed  tomography  scans,  and  retrograde  cannulation  of  the  pancreatic  duct  with  injection  of  dye  and  x-ray  opacification  (endoscopic  retrograde  cholangiopancreatography  [ERCP])  may  demonstrate  a  pseudocyst.  Films  of  the  chest  and  abdomen  may  demonstrate  elevation  of  the  left  hemidiaphragm  with  or  without  basilar  atelectasis  or  pleural  effusion.  Treatment  of  cysts  that  do  not  regress  spontaneously  consists  most  often  of  internal  drainage  via  the  stomach,  duodenum,  or  jejunum.  External  tube  drainage  with  subsequent  fistula  may  be  rarely  indicated.  A  preferential  option  used  by  some  gastroenterologists  is  the  creation  of  a  cystogastrotomy  endoscopically.  In  this  technique,  a  cystogastrotomy  is  made  and  a  stent  placed  to  drain  the  pseudocyst  into  the  stomach.  The  procedure  requires  stent  removal  at  a  later  date  but  avoids  an  operation.
