[Systematic or selective frozen sections during surgery for suspected malignant thyroid lesions? Results in 674 cases over a period of 6 years (author's transl)].

Results of a retrospective study of 674 frozen sections in thyroid surgery, demonstrated on over all reliability of 98.2%, when compared with final pathological findings, with 651 confirmation in 674 cases. False negatives of malignancy represented 1.6% of lesions thought to be benign, while false positives were obtained in 4.8% of lesions thought to be malignant on frozen sections. Prior to frozen sections, 221 patients had needle punctures and cytological smears studies of the thyroid lesion. When comparing the results after using the two methods, no false positive for malignancy, assessed by cytology, was found on frozen sections, which also corrected but two false negatives of malignancy given by the 177 smears affirmative of benignancy, but reduced the number of equivocal results of cytology from 36 to 1. Both pre-operative cytological examination by needle puncture and intra-operative frozen sections appear, therefore, to be very reliable methods for studying thyroid lesions. Frozen sections are complementary to cytological studies. These results suggest that, in surgical thyroid diseases, frozen sections, need perhaps not to be systematically conducted, but should be selective and reserved for cases in which pre-operative needle cytology affirms malignancy, or raises suspicion.

[Pregnancy in obese women who have had jejuno-ileal short-circuit operations (author's transl)].

The authors report two cases of obese women who had had intestinal short-circuit operations for obesity 18 months and 24 months previously. They review the indications for this type of operations and the effects the operation has on the body. It has been possible to find 85 other cases in the literature. In general the pregnancy proceeds well but it is important to carry out very strict supervision of the electrolyte balance, of the hypoprotinaemia and of the blood count. Mechanical complications of the short-circuit operation are rare. While abortions and premature labours are not more frequent in these than in other cases the child is often moderately small-for-dates. Congenital malformations can be raised and are of the order of 7 per cent. These fetal abnormalities, as well as maternal digestive troubles, are definitely more frequent if the interval between the operation and the pregnancy is short. It is therefore preferable to wait for two years before allowing a woman who has had a short-circuit type of operation to become pregnant.

[Early postoperative intestinal obstructions. Contribution of radiography to diagnosis of the type and to the indication for reoperation (experience in 84 cases)].

The authors report 84 cases of post-operative intestinal obstruction and demonstrate the value of straight XRays and barium meal in the diagnosis of the variety of early post-operative obstruction and the indications for operation. In 74 cases out of 82, a precise diagnosis of the mechanical or paralytic nature of the obstruction was made and the operation always carried out under best possible conditions.
