[Tubal choriocarcinoma. A case report (author's transl)].

The majority of the 82 cases of tubal choriocarcinoma reported in the published literature followed malignant transformation of a tubal ectopic pregnancy. The case presented was not related to ectopic pregnancy but was apparently the result of malignant changes in migrating trophoblastic elements during previous pregnancies not arriving at full term. The patient had two abortions by aspiration and had been on oral contraceptives ever since. Fifteen or so of the cases of extra-uterine choriocarcinoma published in the literature appear to have resulted from the same aetiopathogenic mechanism.

[Pulmonary actinomycosis grafted on former tuberculous lesions. Report of one case (author's transl)].

The occurrence of actinomycosis localized in former tuberculosis cavities in a 39-year-old woman is reported. Exeresis of the lesions allowed the discovery of Actinomyces israelii in one of the cavities which no longer communicated with the bronchial tree. In contrast to diffuse actinomycosis found in immuno-depressed patients, this form of the disease was localized in a woman in good health. A decrease of pulmonary defense mechanisms could be involved locally. The infrequency of a tuberculosis-actinomycosis sequence, contrary to aspergilloma, is perhaps due to the anaerobic metabolism of the Actinomyces.

[The resistance to infection of digestive sutures. Experimental study (author's transl)].

The authors study the effects of severe sepsis due to pathogenic gems in large quantity an healing of the suture of the ileum in the rabbit. Contamination of the suture did not lead to any breakdown of the suture whatever the germ. These experimental facts, compared with the data in the literature suggest that the peritoneal serosa ensures efficacious anti-infectious defence, permitting healing of intra-peritoneal digestive sutures in spite of the septic nature of the intestinal contents.

The effect of CO2 laser neurectomy on neuroma formation and axonal regeneration.

In an attempt to prevent neuroma formation and digital reinnervation after sharp palmar digital neurectomy in 10 adult horses with navicular disease, 18,426 W/cm2 of CO2 laser energy was applied to the proximal nerve stump. Clinical follow-up was 4 to 23 months. In two horses, palmar digital nerve biopsies were taken at month 4 (four nerves) and month 7 (two nerves). Nine horses were sound immediately and at all follow-up examinations. None had clinical evidence of painful neuroma or digital reinnervation. Histologically, there was minimal scar tissue at the surgical site; axonal sprouts were comingled with fibrous tissue.

[Urological complications in renal transplantation].

1,224 renal transplant patients were studied. 50 kidneys were obtained from living related donors. The mean age of the recipients was 34.6 years (16.8 to 67.6 years) Ureteric reimplantation was initially performed by uretero-ureteric anastomosis (19%), then into the bladder according to the Leadbetter-Politano technique (69%) and subsequently according to the Lich-Gregoire extra-vesical technique (10%). A cutaneous ileostomy or reimplantation into the renal pelvis was performed in the remaining 2% of cases. The risk of one or more urological complications was 11.2% (137/1,224) and 7.9% when only those patients requiring surgical intervention were taken into account. These complications were classified into 3 categories: strictures (60.6%), fistulae (35.8%) and stones (6.6%). The frequency of urological complications was lower with the Lich-Gregoire technique (4.1%) which we have currently adopted. The renal transplant was lost in 6.1% of cases directly related to a urological complication. The presence of urinary tract fistulae had an unfavourable influence on graft survival due to detransplantations. Whenever possible, our preferred approach consists of percutaneous and/or endourological techniques as first-line treatment followed by second-line surgical treatment in the event of failure of the percutaneous approach.

[The treatment of urinary fistula in renal transplantation].

61 renal transplant patients developed a urinary fistula (4%). The diagnosis was established rapidly (after an average of 12 days) by the presence of urine in the drains and a urine collection on ultrasonography. The exact topographical diagnosis, the nature of the fistula, necrosis or dehiscence, is more difficult, even with modern imaging techniques. The incidence of fistula was decreased by the use of a short ureter, a Lich-Grégoir ureterovesical anastomosis and the prophylactic insertion of a ureterovesical stent. The first 36 ureteric fistulae were treated by open surgery and the last 7 were treated by antegrade stent insertion. 87% of patients were cured of their fistula and retained their transplant: 31 of the 36 patients undergoing open surgery and all 7 patients treated percutaneously. Percutaneous treatment should be proposed as first-line treatment in the case of ureteric fistula after renal transplantation.

[Surgical treatment of hyperparathyroidism in renal transplant patients].

The authors present their experience of surgery for persistent hyperparathyroidism in renal transplant recipients, based on a series of 944 patients transplanted between 1983 and 1992. 56 patients underwent subtotal parathyroidectomy for persistent secondary hyperparathyroidism. Control of serum calcium was excellent in 83% of patients: 2 patients retained a well controlled hypocalcaemia, 2 are still hypercalcaemic and 3 others have developed recurrent hyperparathyroidism. The postoperative course was marked by one death not related to parathyroidectomy and one recurrent laryngeal nerve palsy. Subtotal parathyroidectomy combined with removal of the thyrothymic tissue is an effective operation to control phosphorus and calcium metabolism in patients with persistent hyperparathyroidism after renal transplantation.

[Thoracic traumas and wounds in Libreville. Therapeutic aspects. Apropos of 106 cases].

106 cases of trauma and chest wounds have been treated at the Jeanne Ebori Foundation from 1980 to 1990. They involved 90 men (85%) and 16 women (16%) with an average age of 35. The prevalent etiology was road accidents 55 (52%), followed by assaults 30 (28%). 22 blade wounds and 12 bullet wounds required coordinated surgical and intensive care at resuscitation. 19 pleuro-mediastinal spills, 8 intra-thoracic lesions with 6 vascular wounds and 1 heart wound. Surgical treatment required 13 immediate thoracotomies and in 3 cases with 1 associated laparotomy. We recorded 8 deaths (7%), 75 healings without consequences (71%) and 23 healings with consequences (22%). We noted the extreme gravity of the penetrating wounds especially bullet wounds, as well as that of the poly-traumatisms. This picture requires complex resuscitation management with surgical relays in a precarious respiratory context.
