The methods used for the study of the small bowel are not ideal. Double-balloon enteroscopy is a new alternative with therapeutic potential.
Evaluate the utility, efficacy and safety of double-balloon enteroscopy in Mexico.
Adult patients seen in the Hospital de Especialidades Centro Médico Nacional Siglo XXI, Mexico City who were being studied for: chronic diarrhea, obscure gastrointestinal hemorrhage, weight-loss and chronic anemia were included in the study. Anterograde (oral) and retrograde (anal) approaches were used and study time, findings and complications were evaluated.
Thirty-one enteroscopies were performed, 15 were anterograde, 8 retrograde and 8 were performed via both routes, in 23 patients studied between February and October, 2004; 10 of them were women and 13 men with ages ranging from 25 to 80 years. Fourteen patients were sedated and 9 patients were anesthetized. Study time varied form 55 to 90 minutes. With the anterograde route the ileum was reached in 56.6% of cases, 39.1% the jejunum and only in one patient (4.3%) the whole intestine was explored. With the retrograde route in 62.5% of cases the jejunum was explored and 37.5% the ileum. Four patients with obscure gastrointestinal bleeding and 1 patient with chronic anemia had vascular ecstasies, and in 40% of patients there was no identifiable cause. In 2 patients with intestinal stenosis biopsies revealed intestinal lymphoma in one and ischemic injury in another one. The adverse effects were mild and transitoru.
Double-balloon enteroscopy is a safe diagnostic and therapeutic method that is useful in cases of obscure hemorrhage, chronic anemia; small bowel pathology was found in 64.7% of cases.
用于小肠研究的方法并不理想。双气囊小肠镜检查是一种具有治疗潜力的新选择。
评估双气囊小肠镜检查在墨西哥的实用性、有效性和安全性。
纳入在墨西哥城国家医学中心二十一世纪专科医院就诊的成年患者，这些患者因慢性腹泻、不明原因的胃肠道出血、体重减轻和慢性贫血而接受检查。采用顺行（经口）和逆行（经肛门）途径，并对检查时间、检查结果和并发症进行评估。
2004年2月至10月期间，对23例患者进行了31次小肠镜检查，其中15次为顺行检查，8次为逆行检查，8次为两种途径联合检查；患者中10名女性，13名男性，年龄在25至80岁之间。14例患者接受了镇静，9例患者接受了麻醉。检查时间从55分钟到90分钟不等。顺行途径中，56.6%的病例到达回肠，39.1%到达空肠，只有1例患者（4.3%）探查了整个肠道。逆行途径中，62.5%的病例探查了空肠，37.5%探查了回肠。4例不明原因胃肠道出血患者和1例慢性贫血患者发现血管扩张，40%的患者未发现明确病因。2例肠道狭窄患者的活检显示，1例为肠道淋巴瘤，另1例为缺血性损伤。不良反应轻微且短暂。
双气囊小肠镜检查是一种安全的诊断和治疗方法，对不明原因出血、慢性贫血病例有用；64.7%的病例发现了小肠病变。
