[Pancreatic pseudo-cyst].

Pancreatic pseudo-cyst (PKP) represents a late complication of acute and chronic pancreatitis and of pancreatic trauma. Male sex is predominant (22/27). Average age is 43.9. PKP was most frequently associated with chronic ethylism (16), chronic pancreatitis (14) and acute pancreatitis (9), cancer (1). Ultrasonography (US) is the method used for surgical indication (parietal maturation, content) and lesion follow up. Internal drainage was used for 15 patients: 13 Jurasz cystogastroanastomy and 2 transduodenal cysto duodenostomy. External drainage was used with 9 patients. Topography was: cephalic (4), corporeal (6) corporeo caudal (13); with 4 patients topography could not be set (PKP over 15 cm). Postoperative complications occurred with 7 patients: upper digestive bleeding (4), pancreatic abscess (2), hemi-peritoneum (1). Surgical abstention (3 patients) was determined by: lack of cyst parietal maturation, progressively reduced dimensions and an acute pancreatitis episode. One patient deceased due to haemorrhagic recurrence in tryptic erosion of the portal vein. Surgical decision is supported by US. Surgical tactics shall be adapted to the topography and lesion. Inner derivation represents election indication in mature PKP. In some circumstances, external drainage is however necessary.
