[Surgical strategy in rectosigmoidal cancer].

Colorectal cancer is frequent and diagnosed earlier thanks to the screening and to the progresses in the preoperative assessment. The precocity of the surgical resection takes advantage from the complete resection of vascular and nodes involvement. The rectal localisation of the cancer requires to take the reconstruction into account.

Nuclear DNA content, proliferation index, and nuclear size determination in normal and cirrhotic liver, and in benign and malignant primary and metastatic hepatic tumors.

The distribution values of ploidy, of the proliferation index, of the percentages of diploid cells/case, of nuclear size, and DNA histogram type are described in a series of 92 liver samples from 87 patients. The 92 samples include normal (31 cases) and cirrhotic (14 cases) tissues, benign tumors (7 cases), well-differentiated hepatocellular carcinomas (HCCs, 13 cases), moderately and poorly differentiated HCCs (8 cases), and colorectal glandular metastatic tissues (19 cases). The samples are from either fine-needle aspiration biopsy (FNAB) or histologic imprint smears (HIS).

Heterogeneity of DNA ploidy, proliferation index and nuclear size in human colorectal carcinomas.

Measurements of DNA ploidy, proliferation index and nuclear area were performed on 210 samples taken from 15 human colorectal tissues. The tissues were divided into four groups labeled G1, G2, G3 and C. For each of the 15 tissues 9 samples were taken from the so-called unaffected--i.

[Initial results of a study on morphonuclear parameters at the level of benign and primary neoplastic hepatic tissue].

This study characterises morphonuclear parameters from normal, cirrhotic, tumoral benign and malignant liver specimens obtained by computerized morphonuclear images analyses. The material is obtained by cytological aspirations or by imprint smears from liver biopsy. The monoparametric analysis differentiates a benign and a malignant cellular populations.

[94 inguinal hernias treated by interposition of a prosthesis using medial and preperitoneal approach].

Having chosen the utilization of a Teflon prosthesis, interposed in preperitoneal position by medial incision, in a series of 58 patients presenting 94 hernias, the authors wish to express a preference to this method for reoccurring and bilateral hernias. They underline the simplicity of the technique, its reduced morbidity, and they focus on the infrequency of reoccurrence in 47 patients reseen 6 months to 4 1/2 years in follow up. The authors have not observed a difference in the local results, recent and long term, after intervention using this technique under general or local-regional anesthesia.

[Pyostercoral peritonitis of diverticular origin. Retrospective analysis of 22 cases].

Twenty-two cases of diverticulitis with perforation and peritonity have been treated whether by colostomy (13 cases) or primary resection (9 cases). Primary resection reduces mortality and morbidity of the emergency operation and the combined mortality and morbidity of all operative procedures.

Empyema due to Salmonella dublin.

An alcoholic patient presented with a thoracic empyema secondary to a pancreatic abscess with Salmonella dublin. The absence of an adjacent pulmonary parenchymal infection suggested a transdiaphragmatic passage of organisms.

Azathioprine. An alternative treatment for recurrent idiopathic retroperitoneal fibrosis.

Ureteral obstruction resulting from idiopathic retroperitoneal fibrosis (IRF) generally requires a surgical approach sometimes associated with the administration of a corticosteroid. Corticosteroids alone have also been used successfully for recurrences of IRF after the surgical procedure; however, their success is not uniform. We treated a patient with IRF and ureteral obstruction who showed a dramatic recurrence soon after treatment with prednisone was discontinued.

[Venous thrombosis caused by central catheters. Phlebographic study of 41 cases].

Forty-one central catheters placed in 37 patients were subjected to a twofold phlebographic study - classic angiography of the main veins, and injection of a radio-opaque fluid while withdrawing the catheter under fluoroscopy. Although data from the literature shows a high incidence of venous thrombosis due to central catheters, we only found 3 positive results in our series of 37 patients (8%). A fibrin sheath develops along the entire length of the catheter, and, in cases of thrombosis, the point at which the catheter penetrates the central venous system is always involved.

[Prophylaxis of postoperative deep vein thromboses by means of weak doses of subcutaneous heparin (author's transl)].

The authors intend to control with the marked fibrinogen test, the real frequency of postoperative deep vein thromboses (DVT) and the eventual prophylactic effect of subcutaneous heparin in weak doses. Heparin was administered 2 hours before the operation and every 8 hours during 6 days thereafter, each time at the dose of 5,000 U subcutaneously. Ninety-nine patients undergoing major surgery were randomized into two groups of 55 control operated patients and 44 operated patients treated with heparin.
