[Coloplasty after esophagectomy in cancer. A retrospective study of morbidity and mortality]. / Les coloplasties après oesophagectomie pour cancer. Etude rétrospective de la morbidité et de la mortalité.

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). Patients have been separated in 2 groups: from 1969 to 1983 (group A, n = 22), and from 1983 to 1997 (group B, n = 20). Mortality and morbidity (all eventful postoperative course) have been collected for the 30 postoperative days. Total morbidity has been 57% as 77% in group A and 35% in group B (p < 0.05). Cervical and colo-colic leak have been the most common complications. Total mortality has been 14% as 22% in group A and 5% in group B (p < 0.1). In group A 3 patients died from anastomosis leak (intrathoracic or intraabdominal) and 2 from medical complications. In group B 1 patient died from unexplained sepsis. Our results show significative decrease of morbidity and mortality in group B. These results can be compared to those of gastroplasty for cancer or coloplasty for benign disease. In cancer of the esophagus, if stomach can not be used as substitutes, colon substitution is the best alternative, which can be used without increase of mortality and morbidity.

[Computerized anesthesia record. How far have we gone?]. / La feuille d'anesthésie informatisée. Où en est-on?

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. The technical development concerns computer processing units, RAM or ROM. The development in software influences the operation of networks, multiple task and object programming. The graphic interface becomes the centre of this second revolution. All of these developments should be included in the proposed computerized anaesthetic records. Three factors determine the realisation of such a product: control of the data collecting process, the man-machine interface and the utilisation of storing data. The computerized anaesthetic record should be of open conception, allowing communication with all of the data bases and providing an interface with all the monitors and ventilators used in operating and recovery rooms. Now is the time to install the infrastructure network in operating and recovery rooms and to be thinking of acquiring the new generations of computerized anaesthetic records.

[Pulmonary excisions in patients aged 75 and over. Study of postoperative mortality]. / Les exérèses pulmonaires chez les patients âgés de 75 ans et plus. Etude de la mortalité postopératoire.

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. Post-operative death rate was 15% in patients 75 and over versus 6% in patients under 75 (p = 0.01). Other variables significantly correlated with post-operative death after univariate analysis were: heart failure, Karnofsky score, VEMS, CV, PaCO2, tumor size, right side resection, pneumonectomy and large exeresis. Multivariate analysis retained 6 independent variables affecting post-operative mortality: age > or = 75 years (p = 0.019), Karnofsky score (p = 0.0001), right side resection (p = 0.0002, pneumonectomy (p = 0.04, large resection (p = 0.029) and hypocapnia (p = 0.01). If these parameters are considered when deciding on surgery, pulmonary exeresis may be proposed in elderly patients.

[Intestinal infarctions. A re-evaluation of prognostic factors of postoperative mortality]. / Les infarctus intestinaux. Une ré-évaluation des facteurs pronostiques de mortalité post-opératoire.

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. The risk factors were assessed by univariate and multivariate analysis with logistic regression. The postoperative mortality was 63%. Age, shock, other medical diseases, recent cardiovascular surgery, and length of bowel infarction were significant predictive factors of postoperative mortality on univariate analysis. Shock, age greater than 70 years and recent cardiovascular surgery were three independent risk factors selected on multivariate analysis with equivalent weights.

[Uncommon cardiac manifestations disclosing pheochromocytoma. Apropos of 3 cases]. / Manifestations cardiaques inhabituelles révélatrices du phéochromocytome. A propos de trois observations.

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. The divercity and severity of these clinical situations are such that the possibility should always be suspected when confronted by any cardiomyopathy without obvious etiology, in particular in a hypertensive patient. The only treatment remains ablation of the tumour and diagnosis as an emergency is based, apart from history, on ultrasonography and/or abdominal CT scan and assay of urinary catecholamine derivative levels, which can be obtained within a few hours.

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. All the patients were given cefuroxime (1.5 gm intravenously) at the time of the anesthetic induction and again 2 hours later. The randomization was done postoperatively: group 1 was given placebo intravenously (n = 102) and group 2 was given cefuroxime intravenously (n = 101), each every 6 hours for 48 hours. The overall rate of infections was 46% in the 48-hour cefuroxime group versus 65% in the flash group (p = 0.005). The difference remained significant even after an adjustment with prognosis variables (p = 0.01). Six empyemas (6%) in the flash group were noted versus one (1%) in the 48-hour group (p = 0.03). From day 3 to day 8 after the operation, chest x-rays films were more often assessed as being normal in the flash group than in the 48-hour group (p = 0.005). On day 3 after operation, white blood cell counts were 13,020 +/- 1,220 elements/mm3 in the flash group versus 11,620 +/- 1,220 elements/mm3 in the 48-hour group (p = 0.03). A 48-hour antibiotic prophylaxis regimen decreases the rate of deep infections and particularly the rate of empyemas.

[Endothoracic goiter operated on by cervicosternotomy. Apropos of 18 cases]. / Les goîtres endothoraciques opérés par cervico-sternotomie. A propos de 18 cas.

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. 7 patients had already been operated of a goiter within 1 to 50 years. The substernal goiter was discovered on a systematic x ray chest 5 times, and a x-ray scanner once, also clinical symptoms were still present with compressive troubles in 16 times (particularly acute dyspnea 3 times). The sternotomy was always total. It was only required if the operative problems were important at the time of the cervicotomy. Indications for sternotomy were:--impossibility to extraction due to the volume of the goiter 10 times, (including 5 recurrent goiters), independent retrosternal goiter without cervical connexion, 2 times (including 2 recurrent goiters), hemorrhagic linkage, 3 times, invasive cancer, 3 times. Excluding the 3 invasive cancers, the mortality was inexistant and the morbidity very low, especially without respiratory problems. Post operative complications were 2 definitive hypoparathyroidism and 1 regressive recurrential palsy (plus 2 recurrential palsy still present before the operation). The authors pointed out the good tolerance of the sternotomy which, in special case, should be absolutely preferable the cervicotomy alone, in order to reduce the operative risks, especially hemorrhagic and nervous.

[Lympho-epithelial lesions induced by plasma cells in a pulmonary MALT lymphoma]. / Lésions lympho-épithéliales induites par des plasmocytes dans un lymphome MALT du poumon.

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. Lympho-epithelial lesions were particular because induced by tumoral plasma cells. From this case, problems of diagnosis and physiopathology of pulmonary MALT lymphomas are discussed.

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. Hypocalcemic mice received calibrated grafts from human parathyroid glands cryopreserved between 1982 and 1992 originating from 30 patients (15 adenomas, 15 hyperplasias). Each parathyroid was grafted into two mice under the ratio of one mass-unit (12 mg) and three mass-units (36 mg). The hPTH concentration was assessed by an immunoradiometric method 21 days after grafting. The mean cryopreservation time was 677 days (54-3187 days). The time of cryopreservation was identical in the two kinds of tissue (p = 0.88). The hPTH concentration in 59 living mice was 72.2 +/- 271.4 (SD) ng/ml (3-1936 ng/ml). This concentration was 7.1 +/- 4.3 ng/L for adenomas versus 139.4 +/- 378.6 ng/L for hyperplasias (p = 0.003) and 87.1 +/- 352.6 ng/L for one-unit-mass grafts versus 56.7 +/- 152.5 ng/L for three unit-mass grafts (p = 0.824). Hyperplastic glands showed more secretion, which was confirmed in both mass related groups (p = 0.02, p = 0.006).(ABSTRACT TRUNCATED AT 250 WORDS)

[Colorectal cancers associated with ulcero-hemorrhagic rectocolitis. Detection of and prognosis for postoperative patients]. / Cancers colorectaux sur rectocolite ulcéro-hémorragique. Détection et pronostic des patients opérés.

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). The mean duration of UC symptoms was 19.2 years. The diagnosis of cancer was established preoperatively in 65% of patients, while the remainder of patients, except for three (n = 30, 35%) were at high risk for cancer. A colonoscopy performed in 16 of those 30 patients less than six months prior to the operation did not detect cancer. Overall, cancer was either proven or highly suspected preoperatively in 96.5% of patients, while the sensitivity of colonoscopy was 78%. During the study period, histological tumor features, such as number of tumors, Dukes' stage, Broder's stage, and curative/palliative ratio, remained unchanged, and the five-actuarial survival of 50% did not improve with time (p = 0.37). Multivariant analysis indicated that Dukes' stage and male gender were two poor prognosis factors. For patients with long-standing UC, we offer either proctocolectomy, possibly with ileal pouch-anal anastomosis, or surveillance colonoscopy, emphasizing their respective hazards and limitations.

[Spontaneous pneumothorax. A comparison of thoracoscopy and thoracotomy]. / Pneumothorax spontané. Comparaison de la thoracoscopie et de la thoracotomie.

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. Patients were called by phone to evaluate the surgical and functional results. The questionnaire was filled out by an independent physician who ignored the surgical technique used. Hospital stay was 7 +/- 2 days for thoracoscopy versus 11.5 +/- 5 days for thoracotomy (p < 0.003). During the J30 to J60 period of time, pain was mild in 94% of thoracoscopy cases and severe or unbearable in 69% of thoracotomy cases (p < 0.002). Mobility of the shoulder was fully recovered in all thoracoscopy patients within the first month versus only 62% of recovery at 3 months in the thoracotomy group (p < 0.0001). Working was possible at 1 +/- 0.8 month in the thoracoscopy group versus 2.6 +/- 0.8 months in the thoracotomy group (p < 0.002). Leisure activities were resumed at 2 +/- 1 month in the thoracoscopy group versus 4 +/- 1 months in the thoracotomy group (p < 0.0005). Only one relapse occurred in the thoracoscopy group. Thoracoscopy prevents the drawbacks of thoracotomy but keeps the same efficiency in the treatment of pneumothorax.

[Peristomal pyoderma gangrenosum after colectomy for Crohn disease. Successful medical treatment]. / Pyoderma gangrenosum péri-stomial après colectomie pour maladie de Crohn. Succès du traitement médical.

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.

[Cystic tumor of the mediastinum of digestive origin. Apropos of a new case. Diagnostic and pathogenic hypotheses]. / Tumeur kystique du médiastin d'origine digestive. A propos d'un nouveau cas. Hypothèses diagnostiques et pathogéniques.

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. This new hypothesis was not confirmed by the results of the pathological report which revealed two kinds of tissue; intestinal in the abdomen and broncho-pulmonary in the chest. Two diagnoses where then proposed: complex hamartoma or mediastinal bronchogenic cyst. The pathogenic interpretation in such cases is still very controversial. English authors are prone to classify them as broncho-pulmonary foregut malformations. Macroscopic and microscopic data of the specimen led us to consider our case-report to be a foregut malformation.

[Postoperative morbidity and mortality of infectious complications of colonic diverticulosis: multifactorial study]. / Morbidité et mortalité post-opératoires des complications infectieuses diverticularies coliques: étude multifactorielle.

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). The overall complications were 51% (n = 42) with a mortality of 28% (n = 23). During univariate analysis, variables linked to postoperative complications were neurologic events (p < 0.0001), cirrhosis (p = 0.01), current treatment by steroids (p = 0.007), infectious level (p = 0.002), first colostomy (p = 0.005) and first resection with anastomosis (p = 0.007). Postoperative mortality was linked with neurologic events (p < 0.0001), age (p = 0.005), infectious level (p = 0.04), first colostomy (p = 0.005), and first resection with anastomosis (p = 0.0012). Logistic regression determined 3 independent variables influencing complications: neurologic events (p < 0.0001), first colostomy (p = 0.01), and infectious level (p = 0.002). The mortality determined by multivariate analysis was dependent on 3 variables: neurologic events (p < 0.0001) first colostomy (p = 0.007) and age (p = 0.01). The adjusted relative risk was 17 for neurologic events and 6 for first colostomy.

[Substernal goiters. 218 operated cases]. / Les goitres plongeants. 218 cas opérés.

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 50.5% of patients and hyperthyroidism in 16.5%. Respiratory manifestations were more frequent and more severe in patients aged 70 and more. Moreover 90% of those old patients were symptomatic. Goiters migrated anteriorly in 57.7% of cases, posteriorly in 33.9%, both anteriorly and posteriorly in 5.5%. Type of migration was unknown in 2.5%. 3.7% were malignant. 27 patients with respiratory symptoms received corticosteroids to reduce the airway compression. Among 52 patients with hyperthyroidism, 36 were given antithyroid drugs. Among them, some received corticosteroid drugs in order to reduce risks of mediastinal compression. A simple cervicotomy was adequate in 92.7% of case and was completed by sternotomy in 7.3%. The operation was iterative for relapsing or forgotten thoracic goiters in 24 cases. Morbidity was slight even for sternotomized patients. Mortality was noted in 2 cases (0.9%) one of them operated on for poorly-differentiated and suffocating carcinoma of the thyroid. We advise a straightforward surgical attitude as a result of the slight morbidity and mortality, even in sternotomized patients in order to avoid severe compressive complications of the airways.

[Amikacin concentrations in lung and serum after single intratracheal administration in men]. / Concentrations d'amikacine dans le poumon et dans le sérum après administration unique intratrachéale chez l'homme.

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. Blood was then collected every 15 min for serum assays, until pulmonary resection had been carried out. Pulmonary concentrations were assessed in a healthy area. Measurements were carried out in duplicate using fluorescence polarizing immunoassay and microbiological methods. Serum peak concentrations were found 105 min after administration (7.97 +/- 5.62 micrograms.ml-1). Six and 12 h after administration, serum concentrations were 3.19 +/- 1.87 and 1.20 +/- 0.67 micrograms.ml-1 respectively. Mean lung concentrations were 1.85 +/- 2.12 micrograms.g-1, with a corresponding serum level of 7.22 +/- 4.36 micrograms.ml-1. However, endotracheal instillation of amikacin provided serum concentrations which, were not high enough for treatment of gram negative pneumonia. Lung concentrations are lower than both serum levels and MIC90 for gram negative bacilli. Moreover, there was a major heterogeneity in serum and lung levels, which seemed to be unpredictable. This was probably due to heterogenous tracheal, bronchial and alveolar absorption. The results obtained in this study with a single dose administration should be reassessed in the light of data obtained with long-term amikacin administration.

[Dumbbell neurogenic tumors of the posterior mediastinum. Apropos of five cases]. / Tumeurs nerveuses en sablier du médiastin postérieur. A propos de cinq observations.

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. Neurological signs were observed in two cases. Widening of the intervertebral foramen at the level of the tumor is a very suggestive sign of dumbbell tumor confirmed by CT-Scan or MRI. Precise morphologic features must be assessed before embarking on the operation. The procedures used were: thoracotomy only in two cases, laminectomy then thoracotomy because of neurological signs in two cases, thoracotomy then laminectomy to fully remove tumor remnants in one case. No major morbidity was noted. The neurological symptoms resolved in two cases. A combined two-team approach with thoracic and neurosurgeons working together has not been used so far, but this possibility is probably the best choice for the future.

[Prevention of postoperative wound dehiscence. Comparative study of polyglactin 910 mesh and total reinforced extraperitoneal sutures]. / Prévention de l'éviscération post-opératoire. Etude comparative du treillis de polyglactine 910 et de points totaux extrapéritonéaux appuyés.

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. These patients were divided in two groups according to the methods of abdominal wall support: 226 patients (group I) with total reinforced extraperitoneal sutures and 66 (group II) with a polyglactin 910 mesh. Preoperative risk factors, surgical pathology and the incisions performed were similar in the two groups. Only two parameters were different: the number of previous operations and emergency surgery which were more frequent in group II (p less than 0.05). Fourteen patients in group I developed postoperative wound dehiscence and none in group II (p = 0.02). Nine of these patients were reoperated with a mortality of 28.5%. The frequency of the other complications was similar in the two groups. Polyglactin 910 mesh was more effective than total reinforced extraperitoneal sutures in the prevention of post operative wound dehiscence justifying its use in high risk patients.
