Incidencia y causas de hemorragia digestiva baja Instituto Gastroenterológico Boliviano Japones (1979 - 2005) / Incidence and causes of low intestine blooding at Intitute Gastroenterológico Boliviano Japones (1979-2005)

Resumen El objetivo de este trabajo es de estudiar y determinar retrospectivamente las causas y la frecuencia de presentación de la hemorragia digestiva baja , en pacientes del I.G.B.J, demostrado por endoscopía en un periodo de tiempo de 25 años. Se estudiaron 3591 pacientes (1275 mujeres y 1245 hombres), con diagnóstico de hemorragia digestiva baja, diagnóstico que se hizo en base a datos que fueron recolectados de la historia clínica y hallazgos endoscópicos. Se revisaron un total de 8314 procedimientos endoscópicos bajos, en un período de tiempo comprendido entre enero de 1979 a diciembre de 2005 realizados en el I.G.B.J, de Cochabamba, correspondientes a estudios endoscópicos de pacientes internados u ambulatorios, de diferente edad, sexo y patología. De estos 3591 (43,2%) presentan diagnóstico de HDB, de los cuales 2520 procedimientos (70,2%) son patológicos y 1071 procedimientos (29,8%) fueron normales. De los 2520 pacientes de nuestro estudio, el 49.4% son varones (1245 pacientes), y el 50,6% son mujeres (1275 pacientes). Las lesiones vasculares de tubo digestivo bajo como son las hemorroides, lesiones vasculares y proctitis actínica constituyen el mayor porcentaje causante de HDB, 975 pacientes (38,6%), cuya etiología difiere según frecuencia y según grupo etéreo de lo reportado en la literatura. El índice de mortalidad encontrado es del orden de 0.2 % significativamente menor al de la literatura que es del 5 % , esto probablemente a que en nuestro medio la casuística es menor. Se espera que el presente estudio sea el punto de partida para elaborar nuestro propio protocolo de manejo en nuestro hospital.

Abstract This work is a retrospective study and determine the causes and frequency of lower gastrointestinal bleeding in patients I.G.B.J demonstrated by endoscopy in a period of 25 years. We studied 3591 patients (1275 women and 1245 men), diagnosed with lower gastrointestinal bleeding, that diagnosis was based on data that were collected on clinical history and endoscopio findings. We reviewed a total of8314 low endoscopio procedures, in a period oftime from January 1979 to December 2005 in the I.G.B.J Cochabamba, endoscopio studies for inpatient or outpatient, in a different age, sex and pathology. Ofthese 3591 (43.2%) present diagnosis of HDB, ofwhich 2520 procedures (70.2%) are pathological and 1071 procedures (29.8%) were normal. Ofthe 2520 patients in our study, 49.4% are male (1245 patients) and 50.6% are women (1275 patients). The vascular lesions alimentary canal are as low as hemorrhoids, vascular lesions and ra diation proctitis constitute the largest cause of HDB, 975 patients (38.6%), whose etiology differs according to age group and as often as reported in the literature. The mortality rate isfound in the orderofO.2% significantly lower than in the literature that is 5%, this probably because in our case mix is lower. It is hoped that this study is the starting point for developing our own management protocol in our hospital.

Vitamin B12 deficiency in patient with gastroenterologic symptoms in Can Tho

Background: Several studies reported a high prevalence of vitamin B12 deficiency in some Asian countries and in Asian immigrants living in Western countries. However, there is no data regarding the prevalence of vitamin B12 deficiency in Viet Nam.\r\n', u'Objectives: The aim of this study was to determine the prevalence of vitamin B12 deficiency in patients with upper gastrointestinal symptoms in the Mekong Delta and to investigate the risk factors for vitamin B12 deficiency. \r\n', u'Methods: Blood samples were collected from patients visiting Can Tho General Hospital for upper gastrointestinal endoscopy. Serum vitamin B12 concentration was measured at the University Medical center St Radboud Nijmegen, Netherlands. \r\n', u'Results: Between September and December 2003, 216 patients (80 male, 136 female, mean age 43.2 years) were studied. Ten patients had gastric cancer, 28 peptic ulcer disease/ and 178 gastritis only or no visible pathology. Only 2 patients (0.9%) had clinical vitamin B12 deficiency (<160 pmol/l, whereas 15 patients (7.0%) had sub-clinical vitamin 812 deficiency (160-250 pmol/l). H. pylori positive patients (n=111) were more likely to have para-clinical vitamin B12 deficiency than H. pylori negative patients (odds ratio 3.7~ 95%CI 1.10-12.76). \r\n', u'Conclusions: Vitamin B12 deficiency is uncommon in the Mekong Delta. Helicobacter pylori infection is a risk factor for vitamin B12 deficiency. \r\n', u'

Clinically Important Gastroenterologic Disorders in Korean Elderly / 대한소화기학회지

Although the function of most organ systems in the body decreases with age, aging has relatively little effect on the function of the gastroenterologic organs. This is probably due to the large functional reserve capacity, such as redundancy in the structure of the organ system and excessive production of hormones and enzymes. Most gastroenterologic disorders developed in younger persons may also develop in the elderly. However, the presentation, treatment and prognosis may be different between elderly patients and younger patients. One important thing is the high prevalence of certain disorders in the elderly. For example, the incidence of peptic ulcer, ischemic complications of vascular abnormalities, drug-induced disorders, malignancies, and some other disorders significantly increases with age. These disorders results either from age-determined changes in the gastroenterologic organs or from extragastroenterologic disorders, such as diabetes mellitus, neurologic diseases, and vascular changes. In this paper, an important consideration of common gastroenterologic disorders frequently developed in the Korean elderly is described. In addition, physiologic and pathologic changes of the gastroenterologic organs associated with aging are also discussed.
