[Surgical treatment of post-traumatic mobile costal flaps].

Twelve cases of surgical management of post-traumatic mobile costal flap are reported. An account is given of the indications for surgery and the various types of costal immobilisation suitable for the anatomical features of the flap. The technique is described in detail and the results are discussed.

[Lipid metabolism in newborn infants at birth. Obstetrical-pediatric aspects].

Lipid parameters in the cord blood of neonates and that of their mothers at birth were studied in a series of 67 subjects divides in accordance with prior disease or diseases arising during pregnancy. From the results obtained in this albeit restricted study, agreement is expressed with the literature view that there is a common genetic control of lipid metabolism in the foetus, which is unusual and independent of that in the mother. An interesting, though unexplained finding was the absence of prebetalipoproteins in the cord blood of 71.5% of the control group.

[Observations on lipid metabolism in normal pregnancy and in some pathological pregnancy disorders].

Chemical determination of total and esterified cholesterol and electrophoretic separation of plasma lipoproteins was carried out in a chemico-clinical approach to the pathology of lipide metabolism in pregnancy. In a future study, the investigation will be extended to the neonatal aspect of the problem. 136 women were studied, with 446 samples being taken, specifically: 65 controls, i.e. pregnant women not presenting pathology that might obviously involve lipide metabolism, 36 hypertense pregnant women, 28 diabetic and 7 with gravidic hepatosis. Observation of the data confirms that in pregnancy there is a steady, meaningful increase in cholesterolaemia and that the electrophoretic picture shows a steady reduction in alpha-lipoproteins, with stimulatneous increase in pre-beta proteins, reaching a peak in hepatosis cases, and an increase in beta lipoproteins. All this agrees with functional and teleological modifications in lipide metabolism during gestation.

Importance of the liver in the regulation of platelet activity: effect of its functional exclusion (Eck fistula).

The functional exclusion of the liver, obtained with end-to-side anastomosis of the porta into the cava vein results in impairment of platelet activity. In fact the maximal amplitude and velocity of platelet aggregation in vitro are reduced in animals which undergo the operation and are examined 1 month later. Adding fibrinogen to the platelet-rich plasma after portacal anastomosis restores a normal type of aggregation indicating that the lack of this factor is involved in the phenomenon, even if alterations occurring to platelets may be implied, too.

Liver transplantation with vena cava in situ and selective use of temporary portacaval shunt or portal clamping.

BACKGROUND/AIMS: The recipient hepatectomy with vena cava in situ in liver transplantation has overcome the need of venous-venous bypass thanks to temporary porta caval shunt or portal clamping. METHODOLOGY: 150 orthotopic liver transplants in 137 patients were performed and the vena cava in situ technique was used in 142 (venous bypass in 7, temporary porta caval shunt in 49, portal clamping in 87). The suprahepatic cava veins anastomosis was performed with Belghiti in 97 and piggyback techniques in 45. RESULTS: There were no differences in operative and warm ischemia times nor in blood requirements, while a greater stability of body temperature was documented in the vena cava In Situ group: in the latter temporary porta caval shunt preserved the temperature better than portal clamping (P < 0.01). In anhepatic phase mean artery pressure decreased in veno-venous bypass and increased in the vena cava In situ groups (P < 0.01). The venous return and the cardiac performances (anhepatic phase) were better preserved in the vena cava In Situ group. (P < 0.0001). CONCLUSIONS: Temporary portal caval shunt or portal clamping and piggyback or Belgiti Techniques allow a better hemodynamic stability through out the procedure, obviating the need for veno-venous bypass or fluid overload, if selectively used.

[Proctologic day-surgery. Results of 2000 surgical interventions].

The aim of the study was the evaluate of results of 2000 surgical operations for ano-rectal disease performed in the day-surgery setting (7-24 hours hospital stay) with improvement of both cost effectiveness and patient comfort. From January 1980 to December 1998, 2000 patients underwent surgical operations: 1011 for haemorrhoids; 708 for anal fissure; 172 for fistula in ano; 80 for pylonidal disease; and 45 for anal stenosis. 97.6% of patients were operated on with loco-regional anaesthesia; the others with narcosis and peripheral anaesthesia. The hospital-stay was 24 hours in 697 patients (34.5%), while 1319 (65.5%) operated on under loco-regional anaesthesia were hospitalised for 7-10 hours. Three patients (0.2%) developed acute hemorrhage after hemorroidectomy during the immediate postoperative period. They underwent reintervention under general anaesthesia with a hospital stay of 7 days. Four patients (0.6%) with perianal abscess after internal sphincterotomy underwent incision 10 days after the operation. Two patients with perianal hematoma after sphincterotomy prolonged the hospital stay for three days. In 1048 patients (51.9%) clinical recovery was observed at first follow-up (7 days); 48% had recovered at the 2nd follow-up (14 days). In 1608 patients (98%) anatomical recovery was observed at the follow-up three months after surgery. Patient satisfaction 6 month after operation was high in 79%; good in 27%; low in 1%. These results seems confirm the feasibility of proctological day surgery in almost all patients, with both a considerably cost reduction and enhanced patient comfort and compliance.
