["Simulated walking" in the duplex evaluation of the venous system. The clinical and instrumental correlations].

The goals of non-invasive duplex vascular diagnosis of the venous system of the lower limbs are: 1) To make evaluation of the venous system during deambulation feasible under physiological, pathological and post-surgical or elastocompressive conditions. Moreover, any such evaluation must be achieved using a standardized, easy, highly reproducibly method which is inexpensive and utilizes the diagnostic instruments available. 2) To achieve detailed, selective localization of the valvular and parietal dysfunctions at the basis of any reflux pathology. 3) To identify and quantify venous flux and reflux during deambulation. The present work gives the results achieved over the period of one year after a new method simulating deambulation (Walk System 1 patented) was set up for several utilizations, principally correlated to the use of conventional duplex scanning in studying the venous system. The main purpose of the Walk System 1 is step simulation to uncover the location and extent of venous disease. This application test of: a pneumatic pump which compresses the calf to 100-120 mmHg in 0.3 sec thus simulating muscolar pumping during deambulation; standard 40 mmHg compression of the foot in order to rule out any hemodynamic involvement of the foot pump venous system. We can use this pump in the hemodynamic component, a part, during the step simulation, with synchronism with calf pump in TVP prophylaxis or in vascular therapy; an easy-to-use application software able to quickly pulsed Doppler data of flux and reflux by means of the flux and reflux orthodynamic indices or with measures in ml/sec. The study was performed on 80 lower limbs in normal subjects in order to define the normality range and in 380 lower pathologic limbs. The study has yielded a clinical-instrumental correlation between the hemodynamic data observed during inflation-deflation of the calf cuff, positioning the pulsed Doppler sample volume in the saphenous vein in the saphenous-femoral ostium zone and the underlying venous morphology. The results have made it possible to determine physiological S-F reflux and to establish 4 pathological classes of orthodynamic S-F reflux, each class corresponding to a specific range in the orthodynamic reflux index (class 0 = 0 < RI < 0.25; class 1 = 0.25 < RI < 2; class 2 = 2 < RI < 3.5; class 3 = 3.5 < RI < 6; class 4 = RI > 5) and to a particular morphological conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

A prospective study of local recurrence after resection and low stapled anastomosis in 183 patients with rectal cancer.

Local recurrence is the most serious complication of anterior resection for rectal cancer, usually occurring during the first two years after surgery. Over a five-year period, from 1981 to 1986, 183 patients underwent anterior resection for rectal carcinoma at the Surgery Ward of the University of Ferrara. Patients were followed for two years postoperatively. All operations were performed with staplers and classified according to Dukes, with 43 cases of Dukes' A; 83 cases of Dukes' B; and 57 cases of Dukes' C. In the first 24 months after surgery, the tumor recurred locally in 44 of the 183 patients (24 percent). Dukes' stage, grading distal resection margin, and histopathologic differentiation of the distal rectal ring left in the stapler after anastomosis were assessed to determine a prognostic indicator for the recurrence of the tumor. The stage:recurrence ratio was as follows: A, 1 (2 percent); B, 21 (25 percent); and C, 22 (39 percent). The grading:recurrence ratio was: G1, 13:51 (25 percent); G2, 24:110 (22 percent); and G3, 7:22 (32 percent). The ratio between distal rectal resection margin and recurrence was: 0 to 2 cm, 15:27 (56 percent); 2 to 4 cm, 16:74 (22 percent); and over 4 cm, 13:82 (15 percent). Histopathologic examination of the distal rectal ring was negative for all patients. These data confirm the direct relationship between class and local recurrence and indicate histologic grade and distal resection margin as significant prognostic parameters only when interpreted in the light of staging.

[Primary gastric lymphoma].

Primary gastric lymphoma (P.G.L.), though rare, is nevertheless the most frequent non-epithelial neoplasm of the stomach. The Authors report their experience based on 18 cases of lymphoma observed from 1975 throughout 1989. Diagnostic and therapeutic problems related to the disease are stressed, uncertain in the results the former, still discussed the latter. The crucial role of surgery, either diagnostic or therapeutic, even in advanced stages, is underlined.

[Effects of therapy with aminaftone on chronic venous and lymphatic stasis].

Following a short introduction on the physiopathology of the phlebo-lymphatic system, the results of a study carried out on 114 patients suffering from chronic venous insufficiency (CVI) treated at the Department of General Clinical Surgery and Surgical Therapy of the University of Ferrara are reported. These patients were subdivided into two random groups and treated with common phlebotonic drugs and aminaftone, respectively. Both groups were also subjected to those physical and medical measures that are usually adopted for the treatment of such patients. The therapeutic effects were assessed by comparing symptomatology before and after 90 days of treatment, both subjectively (patient's assessment of the symptoms by means of a scoring system) and with objective methods (measurements and echo-Doppler examinations). The differences between the two groups were statistically very significant in favour of patients who had taken aminaftone. Excellent results were obtained in the treatment of CVI as well as in lymphatic-related pathology (lymphedema).

[Therapy and follow-up of breast cancer. Experiences in 11 years of observation].

Out of 1260 biopsies performed on neoplasias of the breast in 11 years' surgical practice, 463 (36,7%) malignant tumours were encountered. The surgical strategy in the latter cases was based on two basic parameters: a) the histological report on the intraoperative biopsy; b) the clinical stage (TNM). After surgery oncological treatment followed the now universal standard practice: --T1, T2, T3, N+, M0 and T4 independent of N or M: multiple chemotherapy for 6-12 months then periodic check ups as in N- cases. --M1: multiple chemotherapy, hormone and radiation treatment combined in various ways. The results obtained in terms of trouble free periods and survival are in line with reports in the literature including those describing a larger number of cases.

[Our clinico-therapeutic attitude to fibrocystic mastopathy].

The authors relate their experience about Chronic Cystic Disease. They emphasize the frequency of relapses and the risks that such a pathology involves. They finally suggest a surgical treatment plan that, in their opinion, should be applied whenever the patient is a peri-menopausal aged woman who has undergone, at least twice, an operation for a Chronic Mastopathy with a histologically proved epiteliosis. The operation suggests is a total glandulectomy with simultaneous breast reconstruction by means of a prosthesis.

[Surgical therapy of rectal prolapse. Our clinical experience of 12 years of observations].

AA. are reporting their experience on the subject of the surgical treatment of the rectal prolapse in all his clinical forms, during 12 years of activity that has taken place in the clinical surgery of the University of Ferrara. From their casuistry it is shown that usually this pathology is joined with other morbid forms of the small pelvis which vary according to the degree of the prolapse. They emphasize the excellent results obtained and support the surgical way of laparotomy adopted in the treatment of prolapse of II type (incomplete) and III type (complete).

[Carcinoma of the gastric stump. Considerations on 26 observed cases].

The authors report their experience concerning 26 cases of gastric stump carcinoma after gastric resection for benign pathology, observed in about 12 years. The incidence of such disease is 9,2% as regards the gastric neoplastic pathology and 5,2% as regards the benign ulcerous pathology, observed in the same period of time. The removal of the tumour was performed in 18 cases (69,2%), in spite of the stage, in most cases advanced, of the disease. In 7 cases (38,8%) the operation was extended to other organs. In 5 cases (27,7%) the removal was performed in spite of the presence of liver metastases. The survival amounts to 3 (16,6%) patients after 2, 4,5 and 5 years, one of whom suffers from liver metastases. In spite of the better knowledge of the histologic modifications and the phenomena caused by the biliopancreatic rebux and gastric hypochlorhydria, the etiopathogenesis of that disease is still unknown; the prognosis remains still unfavourable, due to the diagnostical delay and the particular aggressiveness of the neoplasm. Therefore, the Authors confirm the necessity for a precocious diagnosis, which only is suitable to improve the immediate and remote results.
