Personal experience in the treatment of acute cholecystitis with percutaneous cholecystostomy in high risk patients and in elderly patients is reported. Between January 1989 and November 1990, 28 patients affected by acute cholecystitis were treated with percutaneous cholecystostomy at Emergency Surgery Department, Verona University Hospital. The patients treated included 13 men and 15 women; 8 of them were under 70 years old, 5 between 70th and 75th and the remaining patients over 75 years old. The suspected clinical diagnosis of acute cholecystitis was confirmed in all cases by ultrasonography (accuracy 95.4%). The percutaneous cholecystostomy was successful in 26 over 28 cases. In all these cases patients had a sudden improvement of their clinical conditions. In one case we failed because the guide-wire slipped out of the gallbladder and we couldn't perform a second attempt for the patient's refuse; in an other case there was the dislodgment of the catheter after less than 12 hours from the cholecystostomy and the patient was operated on. Twenty-two of 26 patients whose conditions were improved by percutaneous cholecystostomy, subsequently underwent elective cholecystectomy. In 2 cases of acalculous cholecystitis the patients did not undergo the operation; in 2 cases because of the elderly age of the patients and their bad cardiorespiratory conditions we preferred not to perform the operation. We had not major complications; 6 patients complained pain irradiating to right shoulder which disappeared within 30-60 minutes from the end of the procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

[The conservative treatment of hepatic abscesses with echo-guided transcutaneous drainage].

Liver abscesses are a rare disease with 80-100% mortality in untreated cases. The advent of ultrasound in the clinical practice has improved the prognosis. Surgery for this disease has a percentage of complications of 15-52% and a mortality of 12-33%. In a review of the literature about 200 liver abscesses treated with ultrasound-guided percutaneous drainage the complications were 7.5% and the mortality was 3%. The authors report their personal experience about 21 hepatic abscesses in 13 patients. Nineteen abscesses were treated with ultrasound-guided percutaneous drainage and two with antibiotics. Six patients had pyogenic liver abscesses, two amebic and in five patients the cultures were sterile. In 9 cases the location was in the right lobe of the liver, in 3 was in the left lobe. One patient had multiple abscesses. The size of the abscesses ranged from 0.5 to 13 cm. We drained with Seldinger technique or direct procedure with Trocar's needle under ultrasound guidance without serious complications and without mortality. In 6 cases the patients had pain during the procedure and in 3 cases medical therapy was necessary. In one case we had a pleuritis for the puncture of costophrenic space. All the patients treated had a complete resolution of the abscesses. The ultrasound-guided percutaneous drainage is the treatment of choice for liver abscesses. But other reports with more patients are necessary to clarify the indications and the ultrasound criteria of recovery.

Free microvascular fibular versus conventional bone grafts.

Free microvascular grafts have many advantages over conventional bone grafts. Above all they do not undergo creeping substitution and live on their own vessels, thus being able to heal quickly and fight infection. Research in rabbits has been done with radiographic, scintigraphic and light and fluorescence histologic examination which demonstrated the high superiority of quality, reliability and rapidity in healing of the microvascular bone transfer as related to avascular ones. Eighty-five cases of free microvascular fibular transfers starting in 1975 are presented including six congenital cases, 12 non-unions, eight osteitis, seven tumors, seven large losses of bone and 45 femoral head necrosis. The failure ratio is very low. Six primary failures were cured by plaster or additional cancellous bone grafts. Four failures (in femoral head necrosis) did not cure due to recession of the graft, its reabsorption or progression of avascular necrosis in two corticosteroid cases.

[The therapy of symptomatic and/or complicated dysontogenetic liver cysts].

Congenital hepatic cysts are a frequent disease, symptomatic in the 16-18% of the cases. The authors report a review of the literature of the last 20 years about 135 treated surgically patients with symptomatic and/or complicated hepatic cysts. They analyse the different models of treatment both surgical and conservative, referring in special way about the alcoholization of the cysts. The authors finally report their personal experience about eight cases.
