Sequential abdominal reexploration with the zipper technique

Frequently, several multiple abdominal reexplorations are needed in patients with acute necrotizing hemorrhagic pancreatitis (ANP) or with persistent intraabdominal sepsis (PIAS). Residual undrained necrotic and septic foci lead to multiple organ failure. To provide wide-open drainage of the abdominal cavity, since 1985 we have performed sequential abdominal reexploration with the zipper technique (SARZT) in 24 patients. Apache II score was used to evaluate expected mortality. In the pancreatic necrosis group, with a mean Apache II score of 31, the expected and the observed mortality were 70% and 29%, respectively. In the PIAS group, with a mean Apache II score of 30, the expected and observed mortality were 60 and 28%, respectively. These results are attributed to the sequential reexploration of the abdominal cavity that permits excision and drainage of necrotic and septic foci.
