ABSTRACT
Background:Capsule endoscopy has been demonstrated to be an effective diagnostic tool for small bowel diseases in a series of small sample researches. However,the results need to be verified by large sample studies. Aims:To investigate the diagnostic performance and safety of capsule endoscopy for small bowel diseases. Methods:Consecutive patients undergoing capsule endoscopy for suspected small bowel diseases from May 2008 to Apr. 2013 in Nanjing General Hospital of Nanjing Military Command of PLA were collected and analyzed retrospectively. Results:A total of 573 patients were enrolled,the overall success rate of the examination was 99. 13%(568 / 573)and the overall completion rate was 88. 38%(502 / 568). The mean time of capsule passing the pylorus was 43. 45 min,and that of passing the small bowel was 287. 21 min. The overall detection rate of small bowel lesions was 53. 52%(304 / 568)and the overall diagnostic rate was 51. 06%(290 / 568). Both the detection rate and diagnostic rate in patients with obscure gastrointestinal bleeding(OGIB) were significantly higher than those in patients with obscure abdominal pain and chronic diarrhea(64. 26% and 62. 46%vs. 41. 72% and 39. 07% ,and 32. 14% and 27. 38% ,P all < 0. 05). Small bowel lesions detected by capsule endoscopy included angiopathy(21. 38% ),ulceration(20. 72% ),neoplasms(14. 47% ),erosion(11. 84% ),and Crohn’s disease(11. 18%),etc. Capsule retention occurred in 2. 29%(13/568)of the patients,and one acute intestinal obstruction and 2 perforations were observed. Conclusions:Capsule endoscopy is a safe and effective diagnostic modality for small bowel diseases. OGIB is the most common indication for capsule endoscopy,and capsule endoscopy is also helpful for evaluation of established or suspected Crohn’s disease.
ABSTRACT
Objective To study the clinical value of capsule endoscopy for small bowel diseases in pediatric and adolescent patients.Methods Clinical data of 61 pediatric and adolescent patients who underwent capsule endoscopy from February 2007 to April 2014 was respectively analyzed.The positive diagnostic results and safety were observed.Results Of 61 patients,the CE procedures were completed successfully in 58 patients,and failed in 3 patients because of the gastric stasis.Forty-one positive lesions were found in small intestine,and the detection rate was 70.69％.Positive findings included angiodysplasias,Crohn' s disease,Meckel diverticula,ulcer,P-J syndrome,protrusion lesion and enteritis,etc.Finally,29 patients were confirmed (50％),3 (5.17％) were misdiagnosed and 1 (1.72％) was missed.Twenty-two patients underwent other small bowel examinations besides the capsule endoscopy.And the accuracy of capsule endoscopy was 81.82％.All capsules were successfully swallowed by the patients and evacuated within two weeks.No complications such as capsule retention or intestinal obstruction occurred.Conclusion Capsule endoscopy is a safe and well tolerated procedure with high diagnostic rate,which has a prospective clinical value in small bowel diseases in pediatric and adolescent patients.
ABSTRACT
Objetivo: verificar as indicações e os resultados do emprego da cápsula endoscópica em uma série consecutiva de pacientes, analisando-se, em especial, os casos de hemorragia de causa obscura e também a relação no momento em que o exame foi efetuado em relação à atividade de sangramento. Análises especiais ainda para os casos de exames inconclusivos, cápsulas retidas e lesões fora do delgado. Material e Métodos: 187 pacientes consecutivos submetidos ao exame do intestino delgado pela cápsula foram analisados. Utilizou-se a cápsula da empresa Given, específica para o delgado (versões M2A e PillCam SB), e as análises de imagens foram efetuadas no software específico deste método, versão 5.1. Resultados: 70,5% (132 casos) dos exames foram indicados por hemorragia de causa obscura (64 casos) ou anemia de causa obscura (68 casos). Diarreia, dor abdominal, suspeita de pólipos e outras menos frequentes foram as demais indicações. Dos 187 casos, em 124 deles observaram-se lesões, sendo 101 lesões em delgado e 23 lesões fora do delgado. Em 29,9% dos casos, a cápsula não observou lesões e, em 3,7% do total de casos, o exame foi inconclusivo. Em 5 casos (2,6%), a cápsula ficou retida. As lesões vasculares do intestino delgado representaram o diagnóstico mais frequente e, quando da análise dos casos de hemorragia em relação ao momento do sangramento, demonstrou-se um percentual de 69,5% de encontro de lesões no paciente com sangramento ativo, 77,7% no paciente com sangramento recente e 64,6% no paciente examinado fora do episódio hemorrágico. Conclusões: a hemorragia digestiva ou a anemia, de causa obscura, foi a indicação mais frequente (70,5%) do exame do delgado com a cápsula endoscópica. Na análise dos resultados em 66,3% dos exames efetuados, a cápsula demonstrou lesões, inclusive fora do delgado. As lesões vasculares foram as mais encontradas e, nos casos de hemorragia/anemia de causa obscura, a capacidade da cápsula em encontrar lesões foi maior nos pacientes que efetuaram o exame durante o episódio hemorrágico, ou logo após do mesmo, do que em pacientes nos quais o exame foi feito distante deste episódio, embora estes resultados não tivessem relevância estatística. Exames inconclusivos tiveram um percentual de 3,7% dos casos e, em 2,6% dos casos, a cápsula ficou retida em estenoses do delgado.
Objectives: to verify the indications and results of the use of endoscopy capsule in a consecutive series of patients, especially the cases of obscure bleeding cause with the moment when the examination was made (related to bleeding activity). Special analysis for the cases not conclusive yet, retained capsules and lesions out of small bowel. Materials and Methods: 187 consecutive patients underwent the small bowel examination by the capsule were analyzed. A capsule from the Given company was used, it is specific for small bowel (M2A e PillCam SB) and the analyses were made in this brand-specific software, version 5,1. Results: in the analysis it was observed that 70,5% of them (132 cases) were indicated by obscure bleeding cause (64 cases) or obscure anemia cause (68 cases). Diarrhea, abdominal pain, suspected polyps and others least often were the other indications. From the 187 cases, in 124 of them were observed lesions, 101 of them in the small bowel and 23 lesions out of it. In 29,9% of the cases the capsule did not observed lesions and in 3,7% of all cases the examination was inconclusive. In 5 cases (2,6%) the capsule was retained. Vascular lesions of the small bowel were the most frequent diagnosis, and the bleeding causes analysis, in relation to the bleeding moment, 69,5% of lesions in the patient with the active bleeding were showed, 77,7% in the patient with recent bleeding and 64,6% in the patient whose examination was out of the bleeding episode. Conclusion: gastrointestinal bleeding and/or obscure anemia cause were the most frequent indication (70,5%) of the small bowel examination with the endoscopy capsule. In the results analysis, in 66,3% of the examinations made, the capsule showed lesion(s), even out of the small bowel. Vascular lesions were the most found and in the obscure bleeding/anemia cause cases the capsules capacity to find lesions was higher in patients that did the examination during the bleeding episode or just after it, than in patients that the examination was done far from the episode. Inconclusive examinations had a percentage of 3,7 of cases and in 2,6% of cases the capsule was retained in small bowel stenosis.

Los reportes publicados se refieren a adultos y poco se conoce de su utilidad en niños. Reportamos la primera experiencia en Venezuela utilizando enteroscopia doble balón en niños, para evaluar aplicabilidad, seguridad y eficacia del método en el diagnóstico y tratamiento de enfermedades del intestino delgado en pediatría. Pacientes y métodos: 9 pacientes, entre 8 y 15 años, utilizando un enteroscopio Fujinon, con una longitud de trabajo de 200 cm y un sobretubo de 145 cm de longitud. Indicaciones: hemorragia digestiva oscura, diarrea crónica y evaluación de síndromes de poliposis. Resultados: 9 procedimientos. La mayor duración fue 60 minutos. Hallazgos: angiodisplasias, divertículo de Meckel, malformaciones vasculares, várices intestinales, enteropatía celíaca, enteropatía alérgica, pólipos. Se modifico la conducta en 9/9 (100%) se realizó terapéutica endoscópica en el procedimiento en 7/9 (77,7%). No hubo complicaciones. Conclusiones: la enteroscopia doble balón es un nuevo método aplicable, útil y seguro para la evaluación del intestino delgado en niños que permite, en un alto porcentaje, modificar la terapéutica y realizar tratamiento específico en el acto, lo cual implica un alto rendimiento del método.
Small bowel diseases are difficult to diagnose in children. With double-balloon enteroscopy is possible to see the entire small bowel and perform therapeutic procedures. Literature reports the use of this procedure in adult population and little is known their utility in children. We present here the first study in Venezuelan children using the double-balloon enteroscopy, to evaluate feasibility, safety, and clinical efficacy of double-balloon enteroscopy in diagnosis and treatment of small bowel disease in children. Patient and methods: 9 procedures in 9 patients, between ages 8 to 15 years, All patients underwent double-balloon enteroscopy using a Fujinon enteroscope length 200 cm, and overtube length of 145 cm. Indications: Obscure gastrointestinal bleeding, chronic diarrhea and evaluation of polyposis syndrome. Results: 9 procedures. Largest duration of procedures was 60 minutes. Findings: angiodysplasia, Meckel diverticulum, vascular malformations, variceal veins, celiac enteropathy, allergic enteropathy, polyps. We changed the usual treatment in 9/9 (100%) and performed endoscopic procedure in 7/9 (77,7%). No patient experienced complications. Conclusion: Double-balloon enteroscopy is a novel, useful, reliable and safe procedure for evaluation of small bowel in children which allows changing therapeutics and performing endoscopic treatment at the same time, with high performance of the method.
ABSTRACT
Objective To evaluate safety, extensity and clinical efficacy and patient tolerance of double-balloon push enteroscopy in diagnosis of patients with small bowel diseases. Methods Thirty cases suspected of small bowel diseases with negative findings of various routine diagnostic modalities were performed double-balloon push enteroscopy from April to July, 2003. Among which 20 cases were patients with gastrointestinal bleeding of unknown origin, and numbers of patient with abdominal pain, chronic diarrhea and partial small intestine obstruction of unknown causes were 5, 3 and 2 cases, respectively. Results The enteroscopy reached to jejunal-ileum transitional area, middle or low portion of ileum and terminal ileum in 9, 17 and 4 cases, with mean examination time ( 40.5 ?12.3) min , ( 64.3 ?18.6) min and ( 78.8 ?11.5) min , respectively. Most of patients were fairly tolerated to the procedure. The lesion was detected in 25 of 30 cases, the total diagnostic yield was 83.3% , and positive diagnostic rates in obscure gastrointestinal bleeding, abdominal pain, chronic diarrhea and partial small bowel obstruction were 80.0% , 80.0% , 33.3% and 100.0% respectively. No procedure-related complications were observed in all cases. Conclusion Double-balloon push enteroscopy was a safe, reliable diagnostic modality of high clinical value for small bowel diseases.
ABSTRACT
Objective To analyze the clinical features of patients with negative double balloon enteroscopy(DBE)findings.Methods A total of 115 patients with suspected small intestinal diseases underwent DBE examination from gastroenterology department of Wuhan University People's hospital on December 2005 to July 2009.The negative and positive cases were 32 and 83 respectively,then compared clinical data of negative group with that of positive group.Results 83 cases with small intestinal diseases were detected from 115 patients by DBE examination,and the daignosis rate was 72.2%(83/115).2 patients occurred acute pancreatitis and 1 occurred hyperamylasemia.The level of initial hemoglobin of negative group was higher than that of positive group(107.938?26.015 vs 93.518?32.367,P=0.016).meanwhile,there were significant difference in clinical symptoms(unexplained alimentary tract hemorrhage,obscure partial bowel obstruction,abdominal pain and diarrhea)between two groups(P=0.035).Moreover,the positive detection rate of unexplained alimentary tract hemorrhage(81.8%)was obviously higher than that of abdominal pain(57.7%)or diarrhea(40%).Conclusion DBE examination is an effective method in the diagnosis of small bowel diseases at present,however,patients with higher level of initial hemoglobin or the main symptoms as abdominal pain or diarrhea should be prudent to choose.
