[Prognostic incidence of blood transfusion in 753 patients operated for colorectal adenocarcinoma].

Do transfusions have a deleterious effect on the survival after surgery for colorectal carcinoma (CRC)? Among 1,221 patients operated on for a CRC between 1969 and 1988, 753 patients having undergone a curative surgical procedure with a follow-up of at least six months were evaluated retrospectively. 134 patients (17.2%) did not receive any transfusion; the others 619 (82.

[Abdominal aortic aneurysm detected by a consumption coagulopathy].

Consumption coagulopathy with clinical symptoms reveals aortic arterial aneurysm in less than 5%. Aneurysmal repair with graft is able to remove hemostasis abnormalities for a long time. The physiopathology of these abnormalities is described here through the study of an operated case.

[Long-term results of surgery of primary hyperparathyroidism].

The late results of operation for primary hyperparathyroidism were analysed in 52 patients operated between 1971 and 1987. All patients have a minimal 5 years follow-up, and answered a mailed questionnaire concerning their present state of health and recent serum calcium level. Recurrent hypercalcemia occurred in 5.

[A case of parathyroid adenoma localized in the middle mediastinum].

The discovery of a parathyroid adenoma in the middle mediastinum is exceptional and fewer than 10 cases have been reported. On the basis of a new case, the authors propose several pathogenic hypotheses: this adenoma develops and/or migrates from the fourth branchial pouch. Preoperative imaging is very useful for guiding the operation via sternotomy.
