Use of endoscopic papillosphincterotomy in the treatment of acute pancreatitis

The authors describe results of using endoscopic papillosphincterotomy in 100 patients with acute pancreatitis. Methods of endoscopic papillosphincterotomy and endoscopic papillosphincterowirsungotomy are presented. The effectiveness of the treatment was 96%. Operative procedures on emergency made up 1%, lethality-1%, complications-3% of the cases.     

The statistics on malignant neoplasms of the urinary and male genital organs in 1987 in the USSR

The USSR statistics on malignant neoplastic diseases of the urinary system and male sexual organs which comprised 5.7 per cent in the total mortality was presented for the first time. More than a 50 per cent increment in the death rate from these tumors was documented between 1975 and 1987. Annually, prostatic carcinoma is diagnosed in almost 10 thousand patients and cancer of the urinary bladder in 15 thousand patients. Maximal prevalence of the disease has been recorded in the Baltic republics, the Ukraine and Byelorussia. The detection rate of the aforementioned diseases, Stages I-II, is about 40 per cent. The estimate revealed that the total number of the registered oncological patients was 100 thousand persons. The problems in organization of the oncological care system, material and technical supplies and professional training should be considered.     

A clinically applicable method to preserve urine and bladder washing cells for flow cytometric monitoring of bladder cancer patients

We describe a method to fix exfoliated bladder cells that is suitable for followup of bladder cancer patients by deoxyribonucleic acid flow cytometry. After fixation with room temperature methanol plus acetic acid (20:1, volume:volume) urine and bladder washing samples from these patients can be stored at room temperature for 3 to 7 days and then assessed reliably for the presence of aneuploidy and the percentage of hyperdiploid cells. For those with active transitional cell carcinoma diagnostic accuracy comparing fresh to fixed specimens was improved from 58 to 92% with urine and from 50 to 100% with washing samples. For patients with a history of transitional cell carcinoma who currently are free of disease the false positive rate remains unchanged after fixation. The procedure described is suitable for use in the outpatient clinic and should permit shipping of samples without refrigeration to a central flow cytometry facility for analysis.     

Angioplasty of the deep femoral artery using a semirigid PTFE prosthesis. Experimental studies

Underlining the importance of Profundus Femoral Artery and its capacity to make up for lower limb's haemodynamics during obliterative arteriopathy, the Authors conceive a funnel-shaped intravascular prosthesis, Goretex constructed (PTFE), to introduce, in case of obstruction, in the artery lumen with a suitable instrument. The research is performed through ten oldster dogs whose average weight is twenty-four kilograms. Isolated the deep Femoral Artery and carried out an arteriotomy of about two centimetres on the Common Femoral Artery, we bring the prothesis in Profundis Femoral Artery and we fix it to the wall of the Common Femoral Artery with 8/O microsurgical dots. After thirty days, the arteriographic test shows the patency of the endoprosthesis with normal peripheral flow in nine animals out of ten. By virtue of this preliminary experiment, the Authors point out the semplicity of this intervention, also feasible in local anaesthesia, the good tolerability of the prosthesis and its perfect integration with the surrounding arterious wall, without shifts or dissecting laminar flows between the external prosthesis wall and the vessel lumen of the animal.
