The increased use of Ultrasonography (US) has led to increased detection of simple hepatic cysts. For symptomatic cysts treatment is necessary. Until some years ago surgery was the only therapy. We have treated a large number of patients with Percutaneous Alcohol Sclerotherapy (PAS) and evaluated retrospectively the efficacy of this approach.Data on 21 patients with symptomatic simple hepatic cysts were reviewed retrospectively. Cysts had a mean diameter of 9 cm (range: 7-15 cm). PAS was always performed under local anesthesia and US guidance. 25% of the volume was replaced with 95% ethanol and then completely aspirated after 20-30 minutes.No complications or deaths occurred. In all patients symptoms disappeared after treatment. In 15 out of 21 cases there was no evidence of residual cyst on US, computed tomography (CT) or magnetic resonance (MRI). In 6 patients with shorter follow-up, cysts showed a mean reduction in diameter of 50%. The mean follow-up was 18 months (range 6-60 months).We conclude that PAS is easy with low risk for the patients and with good long-term results; it should therefore become the procedure of choice for simple hepatic cysts.
patients on percutaneous transhepat ic bi I iary drainageAlthough 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 pmol/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 Four patients were withdrawn from the latter group, two for metastatic cancer and two for complications of PTBD.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 (468 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 ofjaundiced patients, can reduce the rate of complications after biliary and pancreatic surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
