[The retained antrum, its endoscopic diagnosis and clinical significance]. / Antro retenido, diagnóstico endoscópico y significación clínica.

A 65-year-old man was admitted to our hospital with gastrointestinal bleeding. Seventeen years previously, he had a Billroth II procedure for a bleeding duodenal ulcer. A gastroscopy performed on admission showed a stomal ulcer with signs of recent haemorrhage. In the proximal end of the afferent loop, we saw retained gastric mucosa. Histological evaluation confirmed the existence of antrum gastric mucosa. Other diagnostic test for retained gastric antrum were normal. The different approaches in the diagnosis of retained gastric antrum, the importance of our findings and the clinic implications are discussed. We conclude that endoscopic management may be the first diagnostic method in the assessment of retained gastric antrum, and it's possible to find gastric mucosa in the proximal end of the afferent loop (antrum retained), without clinic manifestations.

[Colonic tuberculosis. Endoscopic diagnosis]. / Tuberculosis colónica. Diagnóstico endoscópico.

We present a patient with acute and severe abdominal pain, fever and mild tenderness elicited on deep palpation in the right lower quadrant. X-ray films of the chest and abdomen were normal. The ultrasonographic study, barium enema examination and colonoscopic study avoided a diagnostic laparotomy. A purified protein skin test (PPD) and the cultures on Lowestein medium were negative. The final diagnosis was ulcero-hipertrophic tuberculosis of the ascending colon, and was confirmed by the finding of positive acid fast facilli and granulomas with Langerhans cells in the colonic biopsy material. The colonic lesions disapplared at the end of the antituberculous treatment.

[Acute submassive cholestatic hepatitis after treatment with carbimazole. Presentation of a new case and review of the literature]. / Hepatitis colestásica aguda submasiva tras tratamiento con carbimazol. Aportación de un caso y revisión de la literatura.

Carbimazole, an antithyroid agent of the thioimidazole group, can induce unpredictable liver alterations, presumably by hypersensitivity. We describe the case of a hyperthyroid woman who suffered acute submassive cholestatic hepatitis in the course of treatment with this drug. We also review the other seven cases of carbimazole hepatotoxicity previously communicated in the literature.
