[Coloplasty after esophagectomy in cancer. A retrospective study of morbidity and mortality].

Aim of this study has been to evaluate retrospectively morbidity and mortality of 42 colon substitutions after resection for esophageal cancer. Colon substitution was the intervention of first choice in six patients. In the other patients the stomach was useless, because of previous gastric surgery (n = 14), of gastric involvement by the tumor (n = 21) or technical problem (n = 1).

[Pulmonary excisions in patients aged 75 and over. Study of postoperative mortality].

The aim of this study was to determine what factors beyond age affect post-operative mortality. We included 971 patients (mean age 61 +/- 10 years; 882 men, 89 women). There were 61 patients (6%) 75 years of age and over.

[Computerized anesthesia record. How far have we gone?].

There are more and more computerized anaesthetic records becoming available from various constructors. However, the setting up and operation of such a product depends on the development of concepts in computing. The second technological breakthrough, currently underway, is challenging principles which had seemed accepted up until now.

[Intestinal infarctions. A re-evaluation of prognostic factors of postoperative mortality].

The aim of this study, based on a series of 67 patients, was to assess the prognostic factors of postoperative mortality of intestinal infarctions (small and large bowel). Known risk factors were studied (age, sex, shock, Concomitant disease, use of arteriography and vasodilators), together with less studied factors, such as recent vascular or cardiac surgery less than 4 months before the infarction and length of bowel infarction. Postoperative mortality was defined as any death occurring within 45 days after surgery.

[Uncommon cardiac manifestations disclosing pheochromocytoma. Apropos of 3 cases].

The diagnosis of pheochromocytoma is usually considered in the presence of permanent hypertension with exacerbations. However, pheochromocytoma may be responsible for a varied range of adrenergic symptomatology and hemodynamic equilibrium may be threatened by the spontaneous or induced massive release of pressor amines. Three cases form the basis of a description of unusual situations: acute pulmonary edema, acute circulatory failure and myocardial infarction with normal coronary vessels.

Antibiotic prophylaxis in pulmonary surgery. A prospective randomized double-blind trial of flash cefuroxime versus forty-eight-hour cefuroxime.

The aim of this study was to determine whether a 48-hour antibiotic prophylaxis regimen with a second-generation cephalosporin was more efficient than a flash antibiotic prophylaxis regimen in pulmonary operations. All the included patients underwent lung resection. Patients with preoperative infection were excluded.

[Lympho-epithelial lesions induced by plasma cells in a pulmonary MALT lymphoma].

One case of pulmonary lymphoma of MALT origin is reported. The diagnosis was made by histological and immunohistological study of surgical specimen. Cytologically, the tumoral proliferation was made by an admixture of centrocyte-like cells, small lymphocytes and vacuolized plasma cells.

[Endothoracic goiter operated on by cervicosternotomy. Apropos of 18 cases].

From 1968 to 1992, 18 sternotomies were performed on a total amount of 225 operated substernal goiters (8% of cases). These operations concerned 14 females and 4 males aged of about 67.8 years.

Transplantation of human cryopreserved adenomatous and hyperplastic parathyroid tissue to the hypocalcemic nude mouse.

Cryopreserved parathyroid glands from patients operated on for hyperparathyroidism were stored for further auto- or allografting. In an attempt to better use cryopreserved parathyroid glands in humans, we designed a study whose goal was to compare human parathormone (hPTH) secretion from cryopreserved parathyroid glands with regard to tissue histology (adenoma or hyperplasia), mass, and time of storage in hypocalcemic Nude mice and to be able to better use them in humans. A new hypocalcemic experimental model, using parathyroidectomized Nude mice was set up.

[Spontaneous pneumothorax. A comparison of thoracoscopy and thoracotomy].

The aims of this study were to assess the advantages of surgical thoracoscopy versus thoracotomy. Two 16-patient groups (thoracotomy, thoracoscopy) were compared. They were equivalent with regards to technique, age, etiology and lung dystrophy.

[Colorectal cancers associated with ulcero-hemorrhagic rectocolitis. Detection of and prognosis for postoperative patients].

Between January 1976 and December 1986, 86 patients underwent surgery for colorectal adenocarcinoma (AC) complicating ulcerative colitis (UC) at Mayo Medical Center in Rochester, Minnesota. Seventy-two percent were men, contrasting with only 55% in the population operated for UC without AC during the same time period at the same institution (p = 0.001).

[Postoperative morbidity and mortality of infectious complications of colonic diverticulosis: multifactorial study].

The objective of this study was to determine parameters influencing the mortality due to postoperative adverse events, by taking into account surgical techniques and many other perioperative parameters. From 1967 to 1989, 83 patients were operated for pericolic abscess (level 1, n = 22), pelvic abscess (level 2, n = 38) purulent peritonitis (level 3, n = 16) and fecal peritonitis (level 4, n = 7). Surgical techniques were: first colostomy with drainage (n = 21), first resection without immediate anastomosis (n = 34), and first resection with immediate anastomosis (n = 28).

[Peristomal pyoderma gangrenosum after colectomy for Crohn disease. Successful medical treatment].

A case of Pyoderma gangrenosum with two different abdominal sites in a female patient suffering from colonic Crohn's disease is presented. Local trauma on the midline scar of an incisional hernia and around the stoma were the possible triggering factors. Despite the major abdominal wall defect and an infected parietal collection, steroid therapy was very effective without the need for surgery.

[Substernal goiters. 218 operated cases].

The authors are presenting a retrospective study on 218 retrosternal goiters operated between 1968 and 1991. 33% of the goiters were incidentally discovered on a plain X-ray of the chest. Symptoms of compression were present in 50.

[Cystic tumor of the mediastinum of digestive origin. Apropos of a new case. Diagnostic and pathogenic hypotheses].

An incidental discovery of a posterior and inferior mediastinal cyst-like opacity allowed us to diagnose a pulmonary sequestration in a 45-year old woman. The operative findings showed an hour-glass tumor of the inferior mediastinum with an abdominal prolongation attached by a stalk onto the top of the stomach. These findings made us change our diagnosis in favour of an abdomino-thoracic gastric duplication.

[Cavernous hemangioma of the liver associated with angiosarcoma: malignant transformation?].

Angiosarcoma of the liver is a rare tumor. Its treatment is usually regarded as unsuccessful and its prognosis extremely poor. The authors report the case of a solitary and encapsulated hepatic tumor characterized by the association of a cavernous hemangioma surrounded by an angiosarcoma.

[Prevention of postoperative wound dehiscence. Comparative study of polyglactin 910 mesh and total reinforced extraperitoneal sutures].

Postoperative wound dehiscence is a serious complication. Various surgical procedures have been proposed to prevent it but only few studies have compared their effectiveness. The authors report a retrospective study on 292 high risk patients operated between 1980 and 1988.

[Amikacin concentrations in lung and serum after single intratracheal administration in men].

This study was designed to assess the diffusion into lung tissue and systemic circulation of amikacin administered endotracheally. Eleven consecutive patients, suffering from lung carcinoma and scheduled for elective pneumonectomy or lobectomy, were included in the study. After induction of anaesthesia and before tracheal intubation, a single 500 mg amikacin dose was administered endotracheally through a catheter whose tip was located 5 cm below the vocal cords.

[Practical role of ultrasonography and clinical examination for the diagnosis of acute appendicitis. Prospective study].

The aim of this 100-patient prospective study was to compare three types of investigations in the diagnosis of acute appendicitis: initial clinical examination, initial appendicular ultrasound examination, and final results of repeated clinical examinations carried out within the first 48 hours. Final results included initial evaluation, obvious clinical results and definitive results from patients under 48 hour observation for uncertain diagnosis. Clinical initial or appendicular ultrasound examinations were poorly contributive to diagnosis (overall accuracy: 76 percent).

[Dumbbell neurogenic tumors of the posterior mediastinum. Apropos of five cases].

The authors present 5 cases of dumbbell neurogenic tumors with intraspinal extension. There were 4 neurilemmomas in four adults and 1 ganglioneuroma in one child. These tumors were benign.

[Dumbbell-shaped nerve-tissue tumors of the posterior mediastinum. Apropos of 5 cases].

The authors present 5 cases of dumbbell neurogenic tumors with intraspinal extension. There were 4 neurilemmomas in four adults and 1 ganglioneuroma in one child. These tumors were benign.

[Post-traumatic retroligamentary pneumatocele. Apropos of a case].

A case-report of a 17 year-old man admitted for thoracic trauma associated with a vertical air and fluid collection located behind the pulmonary ligament raises the question of the exact nature of retroligamentary pulmonary pneumatoceles. They may be intraparenchymatous pneumatoceles or simple loculated pneumothorax but whatever the actual lesion, exact recognition of this radiological image avoids drainage and operation. This lesion resolves spontaneously within several weeks.

[Pulmonary metastasis with left intra-atrial extension of liposarcoma. Apropos of a case].

The direct extension of a neoplastic thrombus of the pulmonary veins into the left atrium is extremely rare. The authors report the case of a pulmonary metastasis from a liposarcoma of the thigh extending into the pulmonary veins and prolapsing into the left atrium. The patient was successfully treated by tumorectomy under cardiopulmonary bypass then by left upper lobectomy.
