[Latex allergy].

The incidence of latex allergy has increased in the last decade in particular for medical and health care staff. The "L. Sacco" Hospital in Milan has developed an organisational model for dealing with clinical problems of patients allergic to latex who need to be admitted in hospital. Guidelines have been drawn up to handle the problem of latex allergy in hospital. An Interdisciplinary Working Group has systematically re-examined the epidemiological, etiopathogenetic, clinical diagnostic and therapeutic aspects of this important medical problem. This last topic has been particularly developed to facilitate doctors with emergency drugs. Nevertheless the most efficient method against the sensitisation is the elimination and reduction in hospital of the allergens causing the disease.

Total vascular exclusion of the liver during hepatic surgery. Selective use, extensive use, or abuse?

OBJECTIVES: To review our experience with total vascular exclusion of the liver and to assess its role in hepatic resections. DESIGN: Retrospective survey. SETTING: University hospital, a tertiary referring center for surgical liver diseases. PATIENTS: A total of 722 patients who underwent liver resections from November 1, 1981, to March 31, 1996, of whom 19 (2.6%) required total vascular exclusion because of hepatic lesions closely adherent to or infiltrating the retrohepatic vena cava or centrally located in the liver, strictly in contact with the hepatic vein convergence. MAIN OUTCOME MEASURE: chi 2 Test for qualitative data and Student t test for categorical data. RESULTS: Of the 19 resections carried out under total vascular exclusion, 6 had tumoral infiltration of the retrohepatic vena cava: in 4 cases the venous wall was partially resected, while in the remaining 2 it was completely removed and replaced with a prosthetic graft. There were no operative deaths. Of the 722 resections, 227 were major hepatectomies: 74 (32.6%) were performed after ligation of the glissonian elements for the hemiliver to be removed, without clamping of the hepatic pedicle, and a further 36 (15.8%) were performed without any preliminary vascular control. A significant reduction in intraoperative blood transfusions was achieved despite the performance of more extended operations, regardless of the technique used. CONCLUSIONS: Total vascular exclusion is a useful tool in controlling blood inflow to the liver, but true need for it during liver resection is limited. Its performance requires a well-trained team familiar with problems regarding surgical access to the inferior vena cava and prolonged occlusion of the hepatic pedicle and the inferior vena cava.

Surgical therapy for undifferentiated (embryonal) sarcomas of the liver in adults.

Undifferentiated (embryonal) sarcoma of the liver is a rare malignant mesenchymal tumor with a poor prognosis. Thirty cases worldwide have been reported over the last 40 years. The absence of specific symptoms, the rapid tumor growth, the normality of the common tumoral markers and the consequential delay in the diagnosis, often allow a significant enlargement of the hepatic mass. Three patients ages 15, 25, and 60 were admitted to our department with such a tumor. In spite of the large dimensions of the neoplasms, all underwent a right hepatectomy without any major surgical complications. Two of them died due to tumor recurrence after 10 and 67 months, respectively. The one case remaining is alive and disease free 62 months postoperatively. The latter one was the only case where a complete tumoral capsule was found in the resected specimen. Surgery is strongly recommended for every case with evidence of a liver-confined tumor even if it is large.

Liver resection without blood transfusion.

A retrospective study was carried out of 522 elective liver resections to determine the impact of blood transfusion on the immediate postoperative outcome and on long-term survival. The number of liver resections without transfusion has increased in recent years, as a result of improvement in surgical technique with less blood loss during operation and more careful choice of the timing of transfusion. In resections carried out in the past 5 years, the indication for intraoperative transfusion was restricted and the decision was made jointly by the surgeon and anaesthetist, and in any case only if the haematocrit was below 25 per cent. Of resections carried out in the past 2 years, 59 per cent did not require intraoperative transfusion. Postoperative deaths and complications were related to blood transfusion, particularly in patients with cirrhosis, in whom stepwise logistic regression analysis showed that transfusion was the only factor that correlated significantly with complications. Transfusion also affected the long-term survival of patients operated on for hepatocellular carcinoma and colorectal carcinoma metastases in univariate analysis and was the only factor shown by multivariate analysis to correlate with survival for hepatocellular carcinoma in patients with cirrhosis.

The role of tumor markers in the diagnosis of hepatocellular carcinoma, with special reference to the des-gamma-carboxy prothrombin.

The assessment of new and more sensitive serum markers for hepatocellular carcinoma (HCC) represents a useful contribution to the diagnosis of small liver tumors, still amenable by surgery. We evaluated the efficacy of the tumor markers proposed during recent years for the study of HCC: alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), serum ferritin (SF), tissue polypeptide antigen (TPA), and, finally, the more recently proposed des-gamma-carboxy prothrombin (DCP). Of the 227 patients included in this retrospective study, 111 had HCC, and 85 of these were also cirrhotic. The remaining 116 patients, considered as the control group, included 23 patients with liver metastases from colorectal cancer, 26 with benign hepatic lesions, 20 with tumors other than HCC without hepatic metastases, and 47 with other liver diseases. For each single tumor marker, the sensitivity, specificity, positive and negative predictive values, diagnostic accuracy, and Younden index were assessed. AFP and DCP proved to be the most effective, with sensitivity, specificity, and diagnostic accuracy of 54.9%, 97.4%, and 76.6% and of 53.3%, 88.1%, and 71.1%, respectively. The same parameters evaluated for combined use of the two markers were 74.2%, 87.2%, and 80.9%, respectively. Analysis of the other markers produced no further significant contribution. Of the 111 patients with HCC, 35 (33.3%) were positive for both AFP and DCP, 43 (41%) were positive for one of them, and 27 (25.7%) were completely negative. In the 44 patients who underwent liver resection or transplantation, DCP correlated significantly with the histological presence of microvascular thrombosis, the major factor determining long-term survival after curative surgery. As a tumor marker for HCC, DCP is at least as effective as AFP; the combined use of AFP and DCP significantly improves the chances of identifying HCC by serodiagnosis.

[Lateral calcaneal flap in the reconstruction of the calcaneal and malleolar region].

The authors discuss the efficacy of the lateral calcaneal artery flap in repairing the calcaneal and malleolar regions. The lateral calcaneal artery flap is a safe flap, with constant vascularization represented by the lateral calcaneal artery and the external saphenous vein; the flap has a sensory nerve (the sural nerve) and is a sensory flap. Its use in the calcaneal and malleolar region is very safe, because the vascular pedicle is constant and surgical transfer easy.

[Idiopathic unilateral hypoplasia of the breast].

Unilateral hypoplastic breast is a rare anomaly. The correction of the asymmetry is usually achieved by the use of breast implants or breast expanders. Sometimes the controlateral breast must be modified to gain a good symmetry.

Surgical experience with 168 primary liver cell carcinomas treated with hepatic resection.

Liver resections were performed in 168 patients with hepatocellular carcinoma (HCC) over the past 10 years; 116 were cirrhotics. Operative mortality was 7.7% (8.6% in the cirrhotic group and 5.8% in non-cirrhotics). In the years 1987-1992 the operative mortality decreased from 15.6% to 4.9% (P < .05). A statistical analysis of survival was made with the data of 155 patients with a follow-up of more than 1 month after curative resection: 56 (36.1%) died, while 99 (63.8%) are currently alive, with a follow-up varying from 2 to 76 months. The actuarial survival rate is 56.7% after 3 years and 36.3% after 5 years (59% and 35.2% for cirrhotics; 52.2% and 37.7% for non-cirrhotics, respectively). Satisfactory results can be obtained after liver resections in HCC, even in the presence of cirrhosis. Further efforts are needed in the early diagnosis of HCC, to prevent the formation of satellite nodules and the intrahepatic tumoral spread, which represent the major cause of exclusion from surgical therapy.

Pulmonary artery catheter induced pulmonary artery rupture in patients undergoing cardiac surgery.

Pulmonary artery rupture is a rare but rapidly fatal complication of pulmonary artery catheter insertion and use. Rapid diagnosis and appropriate treatment are essential to avoid mortality. Two cardiac surgical patients who suffered pulmonary artery rupture as a result of pulmonary artery catheter insertion and use are presented. These patients demonstrate two different presentations and the treatment of pulmonary artery rupture. A discussion of diagnosis, treatment, pathogenesis and prevention are presented.

[Macromastia in adolescents: notes on clinical aspects and therapy].

The surgical correction of macromastia is justified on both physical and psychological grounds. Hypertrophy of the breast may alter the development of the body, causing severe damage to the spinal cord. It may also condition the psychological or mental development of the patient, even going so far as to bring about fully fledged psychoses. The definitive scars of the surgical correction are generally accepted by the patients.

Hepatic resective surgery in cirrhotic patients. Techniques and results of anatomical segmentectomies.

The paper describes the technique of anatomical liver segmentectomies based on the extraparenchymal clamping, at the hepatic hilum, of the afferent vascular pedicles. The resection is started on the liver surface along the demarcation line caused by the ischemia. During parenchymal transection the technique of hemihepatic vascular occlusion has been undertaken. The results obtained with 125 segmentary hepatic resections performed for hepatocellular carcinoma arised on cirrhosis are also reported. The overall operative mortality has been 6.4%. The actuarial 1 and 3 year survivals were 93.3% and 70.4% respectively. Hepatic segmentary resections are recommended for limited hepatic lesions, mainly in well compensated cirrhotic patients.
