[Left ventricular involvement in mucoviscidosis after 2 years of age].

BACKGROUND: The cardiac involvement in cystic fibrosis includes the rare cardiomyopathy seen in infants and changes in left ventricular performance in older children. POPULATION AND METHODS: 67 patients, 6 to 34 months-old (mean: 16.7), 37 male and 30 female, with cystic fibrosis, were studied. Their Shwachman score was < 70. None showed any clinical manifestations of left ventricular insufficiency, but 6 patients had right ventricular insufficiency. Echocardiography was performed on 58 patients; it showed dilation of the right ventricle in 32 of them. Left ventricular perfusion was studied with thallium 201 tomoscintigraphy and left ventricular ejection fraction with 99mTc ventriculography. RESULTS: The left ventricular ejection fraction was < 45% in 17 patients and scintigraphy showed hypofixation in 6 of them. In contrast, only 4 of the 50 patients with left ventricular ejection fraction > 45% had thallium hypofixation. CONCLUSIONS: Resting perfusion abnormalities are more frequent in patients with a low left ventricular ejection fraction. These perfusion abnormalities suggest that myocardial fibrosis complicates the advanced stages of cystic fibrosis.

[Simultaneous radiotherapy and chemotherapy in the treatment of advanced cancer of the cervix uteri].

The pelvis is a major site of failure in patients with advanced carcinoma of the cervix. Attempting to improve local disease control, 40 patients were treated between February 1988 and July 1992 with concurrent chemoradiation (CCR). Thirty three patients (group A) with bulky cervical tumors (> 5 cm) received this CCR as the first part of their treatment (stages IB: 4; IIB with distal parametrial involvement: 14; IV: 15). CCR was followed by brachytherapy and a parametrial boost if indicated, then by surgery. CCR was also given, as a postoperative treatment, in seven patients (group B) with a bulky nodal involvement on a previous hysterectomy with lymphadenectomy performed for an early stage. CCR was a pelvic radiation therapy (RT): 45 Gy/25 F/33 d (two fractions per day in the last 14 patients) and a chemotherapy delivering: CDDP 60 mg/m2 on days 1 and 21, followed by 5-FU 600 mg/m2 i.v. continuous infusion for 96 hours (respectively 40 and 400 mg/m2 in the 16 last patients). Median follow-up is 35 months (range 10-63 m). Acute toxicities were grade 3-4 diarrhea in 16 patients and another patient died from a septic episode without leucopenia after CCR. Five post-operative complications required a second surgical procedure. Among these five patients, one died and two other developed small bowel late complications. No post-operative or late complication were observed in patients treated with a bi-fractionated RT. Sites of failure were: pelvic: four; metastases: five, both: three. Thirty months survival and DFS rates were 67.5% and 58.4% in the whole series and respectively 64% and 52.5% in stages IB-IIB patients and 63% and 59% in stage IV patients. Surgery is an important factor of the treatment and a CCR with a bi-fractionated RT allows such a surgical procedure. These encouraging results must be confirmed by a prospective study to determine whether a CCR is able to improve local control and survival.

Results of a prospective study with comparison of clinical, endosonographic, computed tomography, magnetic resonance imaging and pathologic staging of advanced gynecologic carcinoma and recurrence.

Between January 1988 and April 1991, 57 patients with advanced gynecologic carcinoma were preoperatively evaluated by gynecologic examination and endosonography (ESG) using general anesthesia. Abdominopelvic computed tomography (CT) was performed in 49 patients and magnetic resonance imaging (MRI) in 21 patients. There were 34 primary tumors and 23 instances of recurrence. Causes of gynecologic carcinoma were 38 carcinomas of the cervix uteri (26 primary and 12 recurrences), eight carcinomas of the ovary (four primary and four recurrences), three recurrences of carcinoma of the endometrium, five sarcomas of the uterus (one primary and four recurrences) and three primary carcinomas of the vagina. All of the patients were operated upon. This perspective study compares the data from clinical and imaging examinations to the data obtained from histologic examination of surgical sections. According to anterior or posterior tumor extension, the accuracy of clinical evaluation and preoperative imaging were studied for the posterior vesical wall and the vesicovaginal septum and the anterior rectal wall and the rectovaginal septum. Histologic examination revealed vesical involvement in 17 patients and of the involvement of vesicovaginal septum in 21 patients. The accuracy of the clinical examination, ESG, cystoscopy, CT and MRI was 83, 88, 87, 75 and 81 percent, respectively, for vesical extension. Cystoscopy was not taken into account for evaluation of extension to the vesicovaginal septum--accuracy was 80, 90, 67 and 86 percent for clinical examination, ESG, CT and MRI. Histologic examination showed involvement in the rectum in 14 patients and involvement in the rectovaginal septum in 19 patients. Rectoscopy was performed 13 times. The accuracy of clinical examination, ESG, CT and MRI was 91, 98, 89 and 71 percent, respectively, for extension to the anterior rectal wall. Rectoscopy was not taken into account for evaluation of extension to the rectovaginal septum--accuracy was 80, 96, 75 and 57 percent for clinical examination, ESG, CT and MRI. Endosonography would seem to be useful to complete examinations for regional extension of advanced gynecologic carcinomas. Its accuracy is superior to that of other examinations. Because it is performed using general anesthesia, there is no discomfort for the patient during this low cost procedure.

[Rhinosinusal manifestations of cystic fibrosis].

The generalized disorders which characterize cystic fibrosis often involve the nose and paranasal sinuses and may frequently lead to the development of nasal polyps. A retrospective study of 78 patients with cystic fibrosis, 3 to 28 years old, was undertaken in order to determine the incidence of nasal involvement and to define an approach to the treatment of disabling recurrent nasal polyposis. 65% of these patients presented chronic symptoms such as rhinorrhea, nasal obstruction and disturbances of smell. Nasal polyps were found in 50% of patients and were more frequent in adults than in children. Clinical symptoms were directly related to the extent of polyp development which could be classified according to 3 groups. CT scans showed maxillary sinus involvement in almost all patients. The incidence and extent of ethmoidal sinus involvement on CT scans was correlated to the grade of polyp development. Medical treatment of polyposis failed in all cases. Polypectomy was always followed by recurrence. Intranasal ethmoidectomy seems to be an interesting alternative, since 73% of patients undergoing this procedure had clinical improvement.

Lung size matching for double lung transplantation based on the submammary thoracic perimeter. Accuracy and functional results. The Joint Marseille-Montreal Lung Transplant Program.

The present study evaluates the accuracy of submammary thoracic perimeter for lung size matching between donor and recipient and analyzes the influence of donor lung size discrepancies on functional outcome after double lung transplantation. The population is composed of 18 double lung graft recipients, 16 of whom had cystic fibrosis. The lung size match was assessed by comparison of predicted total lung capacity of donor and recipient: five patients were matched in a 10% confidence interval; four received smaller lungs, and nine received larger ones. The functional outcome was assessed with the spirometric values measured at 3 and 6 months after transplantation. The final functional result was not influenced by the lung size (r = 0.142 for total lung capacity; r = 0.372 for vital capacity; r = 0.378 for forced expiratory volume in 1 second). For larger lungs the final result tended to the recipient's predicted, whereas for smaller lungs, spirometry tended to the donor's predicted (r = 0.906 for total lung capacity; r = 0.875 for vital capacity; r = 0.874 for forced expiratory volume in 1 second). The thoracotomy effect, that is, restrictive syndrome at 3 months that resolves at 6 months, was not correlated with the lung size (r = 0.07 for total lung capacity; r = 0.436 for vital capacity). It is concluded that respiratory functional result is not affected by larger lungs; despite the wide range of error, the submammary thoracic perimeter appeared to be a satisfactory selection parameter in this group of patients.

Is lung retransplantation indicated? Report on four patients.

As more lung transplantations are performed, many patients will suffer graft failure and will be considered for retransplantation. This article reviews the case management reports of four patients who received lung or heart/lung retransplantation, with overall disappointing results. The pros and cons of lung retransplantation are discussed.

Double-lung transplantation for cystic fibrosis. The Cystic Fibrosis Transplant Study Group.

One hundred twenty cystic fibrosis patients were accepted for transplantation. Twenty-five patients underwent double-lung transplantation. Twenty-five patients died awaiting transplantation (20.6%). There were 13 female and 12 male patients. Their mean age was 28 years (range, 7 to 34 years), and mean percentage ideal body weight was 76% (range, 58.5% to 91.9%). Most patients were hypoxic and hypercarbic. Two patients underwent tracheal anastomosis, 15 had en bloc bronchial anastomoses, and 8 had sequential single-lung transplants. Operative mortality was 16%; all deaths were related to bleeding from extensive adhesions. Actuarial survival at 1 year was 64%. Rejection and infection were frequent during the first month and decreased thereafter. Airway complications occurred in 5 patients but were amenable to laser therapy and stenting. We conclude that double-lung transplantation is an acceptable modality for the treatment of cystic fibrosis patients with end-stage lung disease. It may be a better alternative to heart-lung transplantation considering the paucity of thoracic organ donors.

Current status of lung transplantation for cystic fibrosis.

Lung transplantation has emerged as an acceptable option for the management of cystic fibrosis patients with endstage lung disease. Heart-lung transplantation and, more recently, double lung transplantation have been successfully performed in this group of patients. The choice of operation, so far, has been based on the surgeon's preference and experience as well as the cardiac function of the patient. Each of the procedures has advantages and disadvantages. This article reviews the current worldwide experience in lung transplantation for patients with cystic fibrosis and highlights the controversies involved in the selection of patients and procedure.

[Diffuse bronchomalacia after double lung transplantation. Thoughts apropos of a case].

A 40 year old woman suffered from respiratory insufficiency (arterial PaO2 = 47 mmHg) because of a chronic beryllium intoxication. On 6th June 1990, she underwent double lung transplantation with cardio-pulmonary bypass. Each lung was separately implanted via an extra-pericardial approach, and both bronchi were anastomosed at the hilum. On the seventh post operative day, a severe bilateral bronchial ischemia was noticed (black mucosa). Few weeks later, a diffuse bronchomalacia was noticed in the proximal and distal parts of both bronchial trees. To our knowledge, such a bronchial post-ischemic complication has never been reported. The explantation could be several added causes: imperfect preservation of the lung during harvesting, post operative pulmonary oedema, and operative use of an antifibrinolytic agent (aprotinin).

[Heart and heart-lung transplantation. 3 years' experience in Timone CHU (Marseilles 1985-1988)].

Since December 1985, we have performed 38 transplantations: cardiac (CT) n: 31, cardiopulmonary (CPT) n: 1, or bipulmonary (BPT) n: 6. There were 31 male and 7 female patients, aged 7 to 62, mean 46. In the cardiac group, the cardiomyopathy was primitive in 13, ischemic in 16, valvular in 2. Five patients had undergone one or more previous operations. Three patients had a biventricular assist device (1,6 and 7 days before transplant) for acute cardiac failure. The indication of CPT or BPT was pulmonary artery hypertension (1), silicosis (1), cystic fibrosis (4). There were 4 post-operative deaths in the CT group (12.9%); failure of graft, low cardiac output, pulmonary artery hypertension by multiple pulmonary thrombosis, and 2 deaths in the CPT and BPT groups (28%). The mean post-operative hospital stay was one month. All patients with CT were treated by an initial maintenance bitherapy protocol (cyclosporine, steroids) and observed by myocardial biopsies and echocardiograms. In 40 per cent of the patients, Azathioprine was subsequently added. The patients had 2.1 rejection episode/patient/year, either spontaneously reversed of treated medically. There were two late deaths (2 and 7 months) by refractory rejection. 78 per cent of the patients were alive one year after transplant. All survivors have recovered a normal life, some of them with full-time work.(ABSTRACT TRUNCATED AT 250 WORDS)

[Double lung transplantation. Report of the 1st French case and comments on the 5 subsequent cases].

Using a modified version of the technique described by the Toronto group, the Marseille group has performed 6 double lung transplantation procedures. In 6 cases the underlying disease was cystic fibrosis. Four patients are currently alive. The technique was modified in two ways. First anastomosis was made on the two main stem bronchi in order to rule out the risk of ischemic complications. Second a special postoperative care technique in which the patient is regularly turned from one side to the other was applied to avoid lymph stasis during the first postoperative weeks.

[Pediatric organ transplantation].

Since we started our pediatric kidney transplant program in 1970, we advocate children's transplantation to be performed in pediatric surgery units. Recent progress in immuno-suppression with ciclosporine and in operative procedures lead us to extend the program to liver transplantations in 1986, then to heart and lung transplantations in 1988. The Pediatric Transplant Unit was designed to assume the pre-operative evaluation of the recipients and the post-operative course of transplanted patients, closely connected to all specialists dealing with medical and surgical diseases of children. 29 patients were transplanted (kidney: 8, liver: 14, heart: 1, lungs: 6) with a 83% overall survival rate. The goal of this paper is not to discuss and compare indications or results with others series. Through our experience of pediatric organ transplantation, we shall try to point out the main advantages of a Pediatric Transplantation Unit: it optimizes the management of the rare pediatric donnors, and allows better skill and efficiency of the numerous specialities concerned by organ transplantation, such as intensive care, infectiology, immunology, radiology... The common medical and para-medical staff, common operative theater, and common use of equipment in the same department for transplantation of different organs is also an important matter to be considered now in term of cost-effectiveness.

[An anesthetic technic in dogs for studying the arrhythmogenic effects of acute coronary occlusion].

Intramuscular injection of levomepromazine (0.5 mg/kg) 30 min before intravenous injection of 10 mg/kg pentobarbital sodium induces a good surgical anaesthesia in dogs artificially ventilated with 50% N2O and 50% O2 and given 0.01 mg/kg atropine and 0.1 mg/kg pancuronium intravenously before left thoracotomy. This protocol is suitable for the study of the arrhythmogenic effects of acute one-stage coronary artery ligation in anaesthetized dogs. In fact, minor interference with the autonomic nervous system appears to be involved since heart rate is maintained slow and mean aortic pressure is kept within normal limits, as pH, PaO2, anc PaCO2 during subsequent periods. Acute circumflex coronary arterio-venous pedicle ligation close to the left main trunk division resulted in this model in a high incidence of ventricular fibrillation (10 out of 15 dogs) early (7 +/- 4 min) after occlusion. Specific interventions aimed at reducing the incidence of early post-ischemic life-threatening ventricular arrhythmias might be tested in this model.

Reconstructive operations for esophagogastric corrosive lesions.

Corrosive esophagogastric lesions are common in Algeria and France. Within the past 14 years, our overall mortality has decreased to 6% as compared to 12% in the best results from elsewhere. This report describes our operative experience with 68 patients from 1974 to 1982. According to a prospective interdisciplinary program, lesions in 351 patients were staged by emergency esophagoscopic findings: Stage I, ulceration; Stage II, hemorrhage and ulceration; Stage III, mucosal necrosis, hemorrhage, and ulceration. Total parenteral nutrition or jejunal feeding was given to patients with Stage II lesions for 3 weeks and to those with Stage III lesions for 3 months before repeat esophagoscopy. Operations were required by 68 patients who had Stage III lesions and severe stenosis. Procedures done included 39 retrosternal colon interpositions, 11 partial or total gastrectomies, nine esophagogastrectomies, four esophagoenteral colonic bypasses, six esophagogastric colonic interpositions following partial gastric resection, and one gastrojejunostomy. Eleven of the cervical anastomoses were to the pharynx. There were no operative deaths and no anastomotic leaks. All patients have satisfactory nutrition and rehabilitation. Our operative experience in the preceding 5 years included an 11% mortality; improved results in the past 8 years are attributed to early and accurate staging, planned multidisciplinary management, good nutritional support, and better timing of operations. Stage III esophagogastric corrosive lesions may be treated within 4 to 5 months of injury with low mortality and good functional outcome.

[Leak-proof intrathoracic esophagogastric anastomosis].

The procedure described is intended for lesions of the middle or lower third of the oesophagus, when 5 cm at least of proximal thoracic oesophagus can be preserved. It involves the use of a gastric tube and is facilitated by mechanical sutures. A new fundus is created, together with a sleeve that protects the anastomosis against leakage.
