Bleeding esophageal varices: today's role of portosystemic shunts.

Emergency portosystemic shunting has once again become a significant option in the management of bleeding esophageal varices and portal hypertension. The decision to perform such a shunt and the choice of shunt procedure requires a rational assessment of the pathophysiology and hepatoportal hemodynamics of the patient's disease and the manner in which it is anticipated that the selected procedure may alter portal flow. Since shunt surgery may interfere with hepatic transplantation, the patient's suitability as a future transplant recipient must also be considered in choosing a shunt procedure. Furthermore, if a shunt is to be performed on an emergency basis to control acute bleeding, this procedure must be done before the patient's condition deteriorates sufficiently to represent a prohibitive surgical risk.

Clinical experience with hepatic resections for hepatocellular carcinoma in patients with cirrhosis.

The results of 31 resections of the liver performed upon patients with cirrhosis and hepatocarcinoma are reported herein. The lesions were discovered mainly during routine echographic surveillance. Twenty-five of these patients with small tumors underwent a segmentary or subsegmentary resection. Intraoperative ultrasonography proved to be of paramount importance in these instances as it helped to recognize the lesion and outline the limits of the resection. In another 11 instances of primary tumors of the liver in patients with cirrhosis who underwent laparotomy, findings from intraoperative ultrasonography advised against exeretic operation because other intrahepatic lesions or neoplastic thrombi in portal branches were detected. The operative mortality rate in the 31 patients who underwent resection of the liver was 12.9 per cent. The actuarial three year survival rate is 58 per cent. The presence of an intact peritumoral capsule seems to be the best prognostic factor.

[Adrenal cysts].

Suprarenal cysts may be clinically silent and discovered by chance, or they may present clinically if they attain marked dimensions by means of compression of surrounding formations. Examinations that lead to precise diagnosis are: direct abdominal X-ray integrated with scanning, echoscanning, urography and selective arterial and especially venous vasography. Two clinical cases that may be considered typical of the two varieties, true cyst and pseudo-cyst, are reported.

[Treatment of cancer of the breast with Patey's modified radical mastectomy].

Patey's operation was used to treat breast cancer in 658 cases between 1956 and 1976 at the Bologna University Surgical Clinic. Follow-up in 562 cases revealed 5-yr and 10-yr survival rates substantially similar to those obtained by Halsted and others. It is felt that the type of operation used is of relative importance for survival, since breast cancer is dependent on other factors that require careful appraisal in each case.

The binding of dimethylnitrosamine to nucleic acids catalyzed by liver enzymic fractions.

The in vitro binding of a metabolite of dimethylnitrosamine (DMNA) to calf thymus DNA catalyzed by a microsomal system from rat liver is reported. The amount ob binding is unaffected by using microsomes induced by 3-methylcholanthrene and/or normal or induced pH 5 enzymes. The microsomal system is also effective in catalyzing covalent binding of the nitroso compound with synthetic polyribonucleotides.

Intensity, latency and duration of post-thoracotomy pain: relationship to personality traits.

The relationship between personality traits and post-surgical pain was studied in 126 patients submitted to a particular set of procedures. The personality was studied by MMPI, STAI, EPI tests before surgery. After surgery, pain intensity was positively related to duration, and pain latency negatively related to both intensity and duration. According to multiple regression analysis, pain intensity was found to be predictable from both the state anxiety and psychoasthenia scales, pain latency from state anxiety and masculinity/femininity, pain duration from aggressivity and hysteria. Results suggest that personality traits constitute strong modulatory factors of the overall pain experience.

Hepatic growths mimicking adrenal tumors.

BACKGROUND/AIMS: The upper district of the perirenal space is widely open and compliant, especially on the right side. Hepatic growths can, therefore, easily invade the adrenal gland area, mimicking adrenal tumors and vice-versa for adrenal and renal tumors. Data on the nature and exact origin of a mass in this region are important for appropriate preoperative management, surgical approach and prognosis but, sometimes, even modern imaging fails in this design. METHODOLOGY: The records and imaging documentation of 42 patients with a mass exceeding 6 cm in the hepatorenal space, have been retrospectively reviewed and compared with surgical and histological findings. RESULTS: Among the 14 patients with "non-functioning adrenal tumors," the preoperative diagnosis had been accurate in all but 2 cases where the suspected adrenal lesion turned out, intraoperatively, to be liver growths. These 2 cases are discussed in detail. CONCLUSIONS: The distinction between an intrahepatic and extrahepatic mass challenges modern imaging techniques, and even invasive procedures sometimes fail. A deceptive diagnosis may lead to inappropriate preoperative management and surgical procedures.
