Absorbable Adams-DeWeese caval clip: an experimental study.
Adams-DeWeese caval clips have been shown to be effective in preventing pulmonary embolism. However, the use of Teflon clips constitutes a permanent solution for this transient risk. We tested an absorbable caval clip made of currently available synthetic biodegradable polymers in five female beagle dogs. The polymer used was PLA 96 containing 96% L lactic acid and 4% D lactic acid. After placement through a laparotomy, clips were routinely inspected and samples of the material were collected at regular intervals between 3 and 19 months postoperatively. The characteristics of absorption of PLA 96 in the retroperitoneal space were the same as those previously described in the literature. The clip retained its shape, rigidity, and effectiveness for 7 months. Complete degradation of the clip took between 18 and 19 months. Absorption did not cause a major inflammatory reaction and had no thrombogenic effect. Given the small number of animals studied, these results must be considered preliminary.

[Expression of blood group antigens in 30 patients with transitional-cell carcinomas of the bladder].
From the follow up of 30 patients whose bladder tumours were repeatedly resected over a period ranging from several months to 18 years, we carried out a study of AGS Antigen expression using an A B O histokit. We were able to establish that this histokit is reliable and very easy to use. We also observed in the urothelial tumours a modification in AGS expression tending towards frequent loss. The AGS staining coincides with the grade of the tumour. Tumours totally stained are always of low grade. However, in this short group of patients, we were unable to draw any interesting correlation between the immunological profile and the clinical course of the transitional bladder carcinomas. In the case of patients with superficial tumours whose histological aspect and clinical course are comparable, the immunological aspect differs. It must be emphasised that in subsequent studies necessary to establish the prognosis of bladder tumours the A B O histokit is easy to use in conjunction with the histological study.
