Abstract
A review was made of the hospital records of 119 patients with pancreatic pseudocysts. Alcoholism, biliary disease and abdominal trauma were the most common antecedent conditions. Abdominal pain was the most frequent symptom, and abdominal tenderness or mass were the most common physical findings. Abdominal echography and contrast study of the upper gastrointestinal tract were diagnostic in 90% of the patients examined. X-rays of the chest, colon, and biliary tract revealed pathology in 30--40% of the patients. Compared to patients with uncomplicated pseudocyst, patients who were acutely ill at the time of external drainage had twice the incidence of postoperative complications. Each subgroup experienced similar, high rates of postoperative death and pseudocyst recurrence. Both groups of patients treated by internal drainage had lower rates of postoperative morbidity, mortality, and pseudocyst recurrence than patients with uncomplicated pseudocysts undergoing external drainage. External drainage should be used in all patients with immature pseudocysts and in critically ill patients with mature pseudocysts not juxtaposed to a portion of the upper gastrointestinal tract. Internal drainage is a safer and more effective procedure in most other patients with mature pseudocysts, irrespective of the clinical status of the patient.
