[Conservative surgery of the spleen (author's transl)].

Total splenectomy has been the accepted treatment for splenic abnormalities, especially traumatic conditions, ever since surgery has been employed. Over the last few years, however, there has been the development of a conservative attitude because of improved recognition of long-term complications, and the application of new diagnostic, hemostatic and technical procedures. This has occurred more particularly in children, but also when iatrogenic lesions develop during operation. The risks and results are comparable to those of total splenectomy.

[Biliary regeneration. Experimental studies in rats (author's transl)].

Cholangiographic and histological examinations after partial hepatectomy in rats have demonstrated the presence of biliary as well as hepatocyte regeneration. Commencing very soon after hepatectomy, biliary degeneration is confirmed by radiological investigation, showing hypertrophy of the intra-hepatic biliary canals, and corroborated histologically by evidence of mitoses in the biliary epithelium. This suggests that intravenous cholangiography can be a simple means of evaluating hepatic regeneration after partial hepatectomy in humans.

[Hyperalimentation after digestive surgery: influence on immune state and on prognosis (author's transl)].

Immunocompetence was measured in 320 gastrointestinal surgery patients using the delayed hypersensitivity test. The frequency of complications and death from sepsis was greater (p less than 0,001) in anergic patients (39%) than in patients with normal response (5%). A close correlation was observed between anergy and malnutrition as determined on the basis of biological criteria (triceps skinfold, arm circumference, ratio between actual and deal weights). This double correlation led to study the influence of hyperalimentation on immune response and prognosis. Parenteral hyperalimentation with nitrogen and calories was administered to 26 anergic patients with heavy or complicated intestinal surgery (peritonitis) for from 10 to 37 days (av.: 19, 2 days). One or more test(s) had turned positive by the 10th day in 7 patients; by the 30th day in 16 and by the 69th day in 20. Out of 26 anergic patients, 19 were nutritionally normal; hyperalimentation had no influence on biological criteria and began to modify body measurements only after 17 days; in the 16 anergic malnourished patients,, hypernutrition led to the development of a positive nitrogen balance (3,60 +/- 1,7 days) and to a return within normal range of biological criteria (7,2 +/- 2,3 days), and body measurements (14,3 +/- 9,2 days). Death from sepsis in anergic patients with hyperalimentation was lower (11,2% and 44,4%; p less than 0,01) than in anergic ones without hyperalimentation. Hyperalimentation with nitrogen and calories modified the nutritional status, immunological response and improved prognosis in anergic patients.

[Value of Noxyflex for peritoneal toilet in acute generalized peritonitis. A controlled study of 48 cases (author's transl)].

The efficacy of Noxythiolin in solution for peritoneal toilet during operation on 48 patients with acute generalized peritonitis was evaluated. The trial was prospective, with random selection of patients who were divided into two groups with identical backgrounds, initial affections, and therapies applied. No significant differences were noted in prognosis, bacteriological findings or subsequent course in the survivors in the two groups. The only favorable effect noted in the group treated with Noxythiolin was the frequency with which further operations had to be performed, but the difference was nos significant. Though the use of peritoneal antiseptics isjustified when positive bacteriological test are reported, the determining element in peritoneal toilet appears to be the volume of liquid employed, independently of its composition.
