Hyperalimentation of jaundiced patients on percutaneous transhepatic biliary drainage

Abstract

Abstract Although percutaneous transhepatic biliary drainage (PTBD) restores hepatic and renal function in patients with obstructive jaundice, it is not certain whether it reduces the rate of complications and death after biliopancreatic surgery. We studied the possibility that the operative risks of jaundiced patients are related to malnutrition and the usefulness of hyperalimentation with PTBD to reduce the incidence of complications. Sixty-four patients with obstructive jaundice and serum bilirubin > 200 μmol/l were randomized into two treatment groups (n = 32) with PTBD or PTBD + hyperalimentation. Four patients were withdrawn from the latter group, two for metastatic cancer and two for complications of PTBD. Before starting hyperalimentation, the incidence of malnutrition was assessed by biochemical, immunological and anthropometric tests: malnutrition was found in 70 per cent of the patients. All the patients had good recovery of hepatic function but patients treated with PTBD alone still had high mortality (12.5 per cent) and morbidity (46.8 per cent) after biliopancreatic surgery. When hyperalimentation was provided to patients on PTBD for a period of 20 days before the operation, the incidence of complications fell to 17.8 per cent and mortality to 3.5 per cent. These results suggest that the combined use of PTBD and hyperalimentation, improving both hepatic function tests and the nutritional status of jaundiced patients, can reduce the rate of complications after biliary and pancreatic surgery.
