G-cells and gastrinaemia in chronic nonspecific bulbitis.

Chronic nonspecific bulbitis (CNB), the number of G-cells in the antrum and the level of serum gastrin were unrelated in a group of 24 patients. Gastrin may be produced by cells outside the antrum or by a few but hyperactive antral G-cells.

Diagnóstico endoscópico de las afecciones del duodeno y yeyuno / Endoscopic diagnosis of duodenal and jejunal diseases

Presentamos y analizamos el diagnóstico endoscópico de la Ulcera Duodenal, Tumores Duodenales y Hemorragia Duodenal. La Ulcera Duodenal se clasifica endoscópicamente de acuerdo a la ubicación forma u estadío evolutivo. Los Tumores Duodenales se dividen para su estudio endoscópico en pólipos, tumores primitivos, páncreas aberrante y linfoma. La Hemorragia Duodenal puede ser diagnosticada según sus causas, (Inflamatorias: úlcera duodenal, duodenitis; tumorales, vasculares: arteriaol, venosa y capilar; traumáticas; externas e internas). Se destaca la importancia de la enteroscopía en sus indicaciones y técnica. Se muestra la experiencia en 313 úlceras duodenales y 98 yeyunoscopías

[Endoscopic diagnosis of duodenal and jejunal diseases]. / Diagnóstico endoscópico de las afecciones del duodeno y yeyuno.

We presented and studied the endoscopic diagnosis of the duodenal ulcer, duodenal tumors and duodenal bleeding. Duodenal Ulcer is classified according as location, form and evolutive stage. Duodenal tumors are divided in polyps, primitive tumors, pancreas anomaly and lymphoma. Duodenal bleeding can be diagnosed according its cause (inflammatory, tumors vascular and traumatic). It is emphasized the importance of the indications and methods of the enteroscopy. We show our experience in 313 duodenal ulcers cases and 98 enteroscopic diagnosis.

[Upper digestive hemorrhage caused by Ascaris lumbricoides in the duodenum]. / Hemorragia digestiva alta causada por Ascaris lumbricoides en el duodeno.

We report a case of upper gastrointestinal hemorrhage due to ascaris in young patient. She presented with hematemesis. Endoscopically ascaris lumbricoides was seen in the duodenum.

Hemorragia digestiva alta causada por Ascaris lumbricoides en el duodeno. / Upper digestive hemorrhage caused by Ascaris lumbricoides in the duodenum

Presentamos un caso de hemorragia digestiva alta asociado con "ascaridiasis" en una paciente joven. La forma de presentacion fue la hematemesis. El "ascaris" fue observado en el duodeno, endoscopicamente

Duodenitis cronica inespecifica (bulbitis). Estudio endoscopico e histologico. / Chronic nonspecific duodenitis (bulbitis). Endoscopic and histologic study

El presente trabajo compredio el estudio de correlacion endoscopica con la histologica en 27 pacientes con el diagnostico endoscopico de bulbitis cronica inespecifica y 6 pacientes con endoscopia normal. Existe una excelente correlacion histologica-endoscopica en las BCI cuando se estudian muestras multiples de duodeno. Ocasionalmente resulta dificil diferenciar histologicamente entre un bulbo normal y una BCI superficial. El aumento del espacio intercelular determinado por microscopia eletronica, pareceria ser muy frecuente en este ultimo grado de bulbitis. La infiltracion celular de la lamina propia y la reduccion de las celulas caliciformes no son elementos confiables, unicos para el diagnostico. Deben existir alteraciones vellositarias y celulares concomitantes para formular el diagnostico correcto de la BCI por medio de la microscopica de luz

[Intermediate gastric cancer]. / Cancer gástrico intermedio.

Gastric Cancer comprises two basic types: Advanced Gastric Cancer (A.G.C.) and Early Gastric Cancer (E.G.C.). A.G.C. extends beyond the proper muscle layer with a 5 to 17%, five years survival rate after surgery. E.G.C. does not extend beyond the submucosa (with or without metastasis to regional lymph nodes) and has a 80 - 95% five years survival rate. Intermediate Gastric Cancer, PM G.C. (Gastric cancer of the proper muscle layer) does not surpass the proper muscle layer and offers a five years life expectance of near 60% after adequate surgical treatment, with peculiar features in radiology, endoscopy and evolutivity. We report a case of PM G.C., "depressed" and "protruded". The proper muscle layer was invaded by the depressed lesion". Both lesions were continguous.

Electron microscopic appearances of chronic nonspecific duodenitis (bulbitis).

The diagnosis of CND cannot be improved by electron microscopy. The normal duodenal cap and CND have similar ultrastructural appearances on guided endoscopic biopsy.

Chronic nonspecific duodenitis (bulbitis).

"Bulbitis" was classified by fiberoptic endoscopy in: superficial, erosive and pseudopolypoid. Endoscopic diagnosis of "bulbitis" is reliable, as good agreement was obtained in 100 cases tabulated according to histological grading. Erosive "bulbitis" implies a severe histopathological compromise.
