Superiority of closed suction drainage for pancreatic trauma. A randomized, prospective study.

During a 42-month period, 65 patients sustaining pancreatic injuries were treated. They were randomized on alternate days (two separate trauma teams) to receive sump (S) or closed suction (CS) drainage. Twenty-eight patients were randomized to S and 37 to CS; there were six early deaths, which precluded drainage analysis, leaving 24 evaluable S patients and 35 CS patients. Penetrating wounds occurred in 71% and blunt in 29%. No significant differences appeared between the groups with respect to age, Penetrating Abdominal Trauma Index (PATI), Injury Severity Score (ISS), or grade of pancreatic injury. Twelve patients in each group required resection and drainage for grade III injuries, with the remaining patients receiving external drainage alone. Five of twenty-four S patients versus one of thirty-five CS patients developed intra-abdominal abscesses (p less than 0.04). We conclude that septic complications after pancreatic injury are significantly reduced by CS drainage. Bacterial contamination via sump catheters is a major source for intra-abdominal infections after pancreatic trauma.
