[Early reoperation in chylothorax after thoracic surgery].

Chylothorax is a rare complication of thoracic surgery. The chyle leak can induce serious metabolic and immunological disorders. The ideal treatment of chylothorax has not been clearly established, and opinions are still divided between medical treatment and early or late surgical reoperation after prolonged medical treatment. Out of a total of 1.750 thoracic operations performed at the Centre Chirurgical du Val d'Or over the last 10 years, six cases of chylothorax were reoperated early, an average of five days after the initial operation. The chyle leak was easy to localize in every case. The second operation was performed via the same initial incision. All six patients has an uneventful postoperative course and only one case had a persistent chyle leak which gradually resolved. The mean total hospital stay was 18 days. No systemic infections or deaths were recorded. Early reoperation avoids the complications of prolonged medical treatment, is technically easy and decreases the length of hospital stay.

[Refractory hypoxemia caused by transient opening of the foramen ovale after pneumonectomy].

A patient with bronchogenic cancer underwent right pneumonectomy. Surgical and infectious criteria were normal during the postoperative period when immediate postoperative severe hypoxeamia occurred. Pure oxygen only incompletely corrected the situation. Transoesophageal echocardiography with injection of microbulles for contrast imaging demonstrated a right-left shunt due to an open foramen ovale. Reopening the foramen ovale is rare but well documented complication of pneumonectomy. The pathogenics is still debated since hyperpressure in the right atria usually is not present. Echocardiography with contrast test is the best means of making the diagnosis.

Effects of holmium:YAG laser on equine articular cartilage and subchondral bone adjacent to traumatic lesions: a histopathological assessment.

This study was performed to investigate the effects of holmium:yttrium-aluminum-garnet (Ho:YAG) laser energy on articular cartilage and subchondral bone adjacent to traumatically created cartilage lesions in a continuous weight-bearing model. The 2.1-microns wavelength was delivered efficiently and precisely in hand-controlled contact and near-contact hard tissue arthroscopic surgery in a saline medium. Bilateral arthroscopy was performed on normal antebrachiocarpal and intercarpal joints of four adult horses. One hundred twenty traumatic lesions were created on three weight-bearing articular surfaces with a knife, curet, or motorized burr. Depths of the lesions were partial and full thickness. Configurations of the lesions were lacerations, scrapes, and craters. Left limbs were used as controls. Right limb lesions were treated with various intensities of laser energy: 0.1. 0.16, and 0.2 J. Animals were killed at intervals of 1, 3, and 8 weeks. Gross microscopic anatomy was documented, and tissue sections were subjected to blind review by a pathologist. Mankin grading for cellularity and proteoglycan content was used to qualitatively evaluate cartilage response. Cartilage adjacent to all lesions exposed to laser energy had better cellularity and proteoglycan content (p < 0.05) than did corresponding controls by Mankin grading. Mankin grades for levels of 0.16 and 0.2 J were lower (p < 0.05) than were those of controls or lesions exposed to 0.1 J. There was loss of cellularity and necrosis in subchondral bone at higher energy levels (0.16 and 0.2 J). This study examined the effects of Ho:YAG laser on articular cartilage and subchondral bone in terms of depth of damage and healing response over time in a weight-bearing model. Additional research to define dose-response curves for Ho:YAG laser treatment of cartilage and subchondral bone are indicated.

[A new technique of posterolateral thoracotomy with preservation of the latissimus dorsi muscle].

The authors present a new posterolateral thoracotomy technique, preserving the integrity of the latissimus dorsi muscle, which in split in the direction of its fibres instead of being sectioned transversely. The exposure is sufficient for all forms of lung resection and pleural surgery and the incision is easily and rapidly repaired. After describing the technique, the authors review their first 70 patients operated via this incision, which was always sufficient to allow the planned operation. Healing was satisfactory and, in the long-term, the functional and painful sequelae appeared to be less than with the classical Crafoord posterolateral thoracotomy, which could be replaced by this new incision.

[Cicatricial stenoses of the trachea. Etiological and therapeutic aspects. Apropos of thirty operated patients].

From January 1984 to march 1990, we performed 30 tracheal resections for post-intubation or post-tracheostomy inflammatory stenosis. After discussing the mechanism and the pathology of the tracheal lesions, we emphasise the importance of careful history taking when evaluating a patient with tracheal stenosis in order to distinguish patients with normal lungs (who needed respiratory resuscitation for acute and reversible respiratory failure) from patients with compromised lungs (patients with chronic pulmonary disease who needed respiratory resuscitation for acute respiratory failure). When selection of the patients was good and evaluation careful, tracheal resection was rater easy, with uneventful postoperative course and good long-term results.

[Radiation-induced sternal tumors: value of myocutaneous flap of the latissimus dorsi].

Two patients treated by radiotherapy, one 13 years previously for Hodgkin's thymoma and the other 10 years previously for breast cancer, presented with a radiation-induced sternal tumour. The first case had undergone manubriectomy for fibrosarcoma complicated by dehiscence of the skin wound one year prior to referral to our unit: she presented with a haemorrhagic ulcerated recurrence. The lesions were widely excised (skin defect: 13 x 13 cm). The second patient underwent "en bloc" cutaneo-osteomyopericardectomy with omentoplasty onto the pericardium and sternal prosthesis (skin defect: 12 x 7 cm). These tumours are rare, but the radiation-induced skin damage requires wide excision. In both cases, the skin defect was easily repaired by means of a latissimus dorsi myocutaneous flap.

[Surgery of bronchogenic cancer in aged patients].

The lung cancer mortality rate increases with age, but the progressivity and radioclinical features of this cancer in the elderly are not very different from those observed in younger subjects. As in these subjects, the pretherapeutic evaluation must be complete whenever surgery seems to be possible, but special attention must be paid to the cardiovascular system. Several recent studies have reported postoperative mortality and morbidity rates paradoxically similar, or even lower, in both old and relatively young patients, probably because of a better selection. Moreover, the survival rate at 5 years of the elderly compares favourably with that of younger subjects. Thus, age is not an absolute contra-indication to surgery, but it requires a more rigorous selection and a closer postoperative supervision.

[Spiegelian hernia. Apropos of a series of 31 cases].

31 cases of spiegelian hernias are reported. It is one of the world biggest statistics of this affection. The patients were divided in 18 women and 13 men, with an average of 45 years old. The hernia was located on the right side of the abdomen in 16 cases and on the left side in 13 cases. In two cases, the affection was bilateral. In 14 cases, there was an incarceration. No strangulation was observed. The rare forms can be divided in massive form, tumoral, crawling (in the old man), spread (in the infant and the woman). The spiegelian hernia can be associated with one or more other kinds of hernias. 27 patients underwent an operation. In all the cases, an direct approach was used. There was no post operative complications. We want to emphazise the high frequence of this affection in Gabon, and the fact that most of the cases have been observed within the same area, in the south of the country. A study researching predictive factors could be interesting to be realised in this area.
