[Analysis of 34 cases of distal hypospadias treated by modified Koff's technique]. / Análisis de 34 casos de hipospadias distal intervenidos mediante la técnica de Koff modificada.

Koff's procedure in the treatment of distal hypospadias consist in a large mobilization of the distal urethra. The association to a transglandular funelization and minimal urethroplasty is useful for the treatment in the majority of patients with distal hypospadias. In the last two years 34 patients with distal types of hypospadias were operated with a Koff's modified procedure. The technique consists in a urethral advancement without glanduloplasty and distal cutaneous tubulization. The primitive meatal localization was subcoronal (n = 22), glandular (n = 6), and on the distal shaft (n = 6). In 10 cases urethral catheters was not necessary. A patient develops a proximal fistula successfully treated with 14 days catheterization. Cosmetic and functional results were good in all cases. Extensive urethral mobilization can be done in cases of distal hypospadias and is evidence of the preserved vascularity and viability of the mobilized urethra.

[Intralobar pulmonary sequestration with multiple arterial blood supply]. / Secuestro pulmonar intralobar con irrigación arterial múltiple.

We report the case of a 4 years old boy, who presented at our institution with reiterative neumonia affecting left basal lobe. Anomalous vascular appearance was detected in the chest x-ray. With the suspicion of pulmonary sequestration we carried on Digital Intravenous Angiography by Substraction (DIVAS) and aortogram. The anomalous systemic arterial supply was formed by 6 vessels coming from the thoracic aorta and going into the left lower lobe basal segment. Lobectomy was performed and previous diagnosis was confirmed pathologically.

[Volvulus of the small intestine. Contribution of abdominal echography to early diagnosis]. / Volvulo de intestino delgado. Contribucion de la ecografia abdominal al diagnostico precoz.

We report six cases of small intestine volvulus associated to malrotation, out of a whole of 11 volvulus managed by us in the last six years. None of them were diagnosed with the only help of clinical and conventional radiological explorations. In the other three cases the diagnosis was made through ultrasounds explorations: It showed the mesenteric vein on the left side of the mesenteric artery. Confirmation and resolution of the cases were reached with a laparotomy.

[Ectopic gastric mucosa in the proximal esophagus]. / Mucosa gástrica ectópica en esófago proximal.

Gastric mucosa is not found often in the proximal and medial esophagus. Hematemesis and dysphagia are the most frequent symptoms. We report a six year-old child who complained of difficulty in swallowing. A filling defect was detect in the esophagogram. We biopsied the suspected area, through an endoscopy and the pathological examination informed of ectopic gastric mucosa. We performed a 99Tc isotopic study. The child is on ambulatory controls and at the moment is asymptomatic.
