[Retroperitoneosotomy in the surgery of pancreonecrosis]

Extraperitoneal, transperitoneal and combined peritoneostomy was used in 29 patients with acute pancreonecrosis and predominant damage of retroperitoneal fat. The choice of surgical method depended of the volume of damage of pancreas and retroperitoneal fat. The wide opening of necrotized zones of retroperitoneal fat, removal of necrotized tissues and adequate drainage can stop further spreading of suppuration of the retroperitoneal fat. The mortality rate was 6/29 (20.7%).
