Table 4 Outcome data of patients undergoing liver resection with PM (A) or with IP + PM (B)

Group	RPC (units) mean/range	ALT (U/L) mean/range	Bilirubin (mg/dL) mean/range	LF (n) transient/fatala	Biliary compl. (n) major/minor

^aDeath;

^bRequiring re-operation. Total complication rate was 14/30 (45%) in controls (A) and 6/31 (20%) in the IP group (B). One death in the study group (B) resulted from a perforated duodenal ulcer (postoperative day 21). RPC: Red packed cells; ALT: Alanine aminotransferase; LF: Liver failure; compl.: Complications.
