Few data exist regarding nutritional assessment during pancreatic abscess. We compared nonprotein caloric requirements calculated by Harris-Benedict equation and measured by indirect calorimetry in patients with pancreatic abscess. Seven patients with pancreatitis and pancreatic abscess had determinations of resting energy expenditure via Medicor metabolic cart with 20% added for activity. Caloric requirements were also estimated using the Harris-Benedict equation with stress factors. Determinations from indirect calorimetry ranged from 22.4-46.8 (mean 36.1) kcal/kg/d. Harris-Benedict calculations with stress factor 1.7 differed from indirect calorimetry by at least 15% in seven of ten determinations. Stress factor 1.9 results overestimated indirect calorimetry by over 25% in four of ten determinations. Energy requirements via indirect calorimetry of some patients with pancreatic abscess cover a wide range and do not correlate with Harris-Benedict calculations. Harris-Benedict equation with a stress factor of 1.9 may estimate adequate nonprotein calories for hyperalimentation, but there is risk of overfeeding.

Twenty-one consecutive patients with pancreatic abscess were managed by an open packing technique. Despite an anticipated mortality of less than 65 per cent predicted by Ranson's prognostic signs, the mortality in this group of patients was only 14 per cent. The marked improvement in results was attributed to several factors: earlier diagnosis and surgical intervention based upon serial abdominal tomography; prevention of persistent or recurrent sepsis by frequent scheduled dressing changes, and prevention of frequently related complications. Seven patients were found to have significant anaerobic involvement. All wounds were permitted to heal by secondary intention, and each patient received intravenous hyperalimentation. The average duration of hospitalization was 76 days, a period not differing significantly from that required by conventional closed methods of drainage. Open packing of pancreatic abscesses appears to represent a significant advance in the management of these difficult patients.

Twenty patients with pancreatic abscesses were studied to determine if recent diagnostic and therapeutic advances have improved the outlook for those with the disease. An abscess developed as a complication of alcoholic pancreatitis in 10 patients and was due to previous surgery in 9. Ultrasonography and computerized tomographic scanning of the abdomen were helpful in the diagnosis and localization of the abscesses. All 20 patients were treated surgically. Operative mortality was 30 percent and was due to multiple system failure from continuing sepsis. Only 2 of 15 patients who had sump drainage died compared with 3 of 4 patients who were drained with Penrose drains alone. There were two deaths among 10 patients who received nutritional support and four deaths in 10 patients who did not receive hyperalimentation. Pancreatic abscess remains a life-threatening condition. Ultrasonography and computerized tomographic scanning have helped in diagnoses and localization. The addition of sump drainage has reduced the mortality rate from 75 ot 13 percent. Nutritional support also appears to be helpful in reducing mortality.
