RESUMO
INTRODUCTION: several studies have pointed out the effectiveness of the PillCam colon capsule endoscopy (CCE) compared with the colonoscopy in the study of the colonic pathology. AIMS AND METHODS: the objective of our study was to assess the agreement in the diagnosis of CCE with conventional colonoscopy as well as its sensitivity and specificity, and to describe the findings of the CCE in our clinical practice. Consecutive patients with abdominal symptoms were included in the study. The CCE was performed as previously reported (with PEG and sodium phosphate as laxative agents). The nature and location of the findings, colonic transit time, complications, cleanliness degree and consistency with diagnostic colonoscopy, when performed, were analyzed. RESULTS: a total of 144 subjects (67 women and 77 men); (52.17 ± 16.71 years) with the following indications were included: screening of Colorectal cancer (88 patients), control after polipectomy (24), incomplete colonoscopy (7), rectal bleeding (10), anemia (8), diarrhea (7). The CCE exploration was complete in 134/144 cases (93%), with no case of retention. The preparation was good-very good in 88/134 (65,6%), fair in 26/134 (19,4%) and poor in 20/134 (15%) of the cases. The average colonic transit was of 140.76 min (9-603). Any adverse effect was notified.In 44 cases a colonoscopy was carried out after CCE (results were hidden from another endoscopist). Compared to colonoscopy, the rate of agreement was 75,6%, the sensitivity was 84% and the specificity 62,5%, PPV was 77,7% and NPV was 71,4%.The colonic findings in 134 CCE were: in 34 cases CCE it did not show lesions, diverticulosis in 63 explorations, polyps in 43, angiodysplasias in 15, Crohn's Disease in 9 and ulcerative colitis in other 8 cases. CONCLUSIONS: the CCE is an effective and reliable technique for the detection of lesions in colon, and because of its high agreement with the colonoscopy, it could be useful in clinical practice. Further studies with large seria and cost-effectiveness analysis are needed to confirm these data.

OBJECTIVE: To evaluate the type, frequency, and severity of macroscopic small bowel mucosal injury after chronic NSAID intake as assessed by capsule endoscopy (CE), as well as to correlate the severity of gastroduodenal and intestinal damage in these patients. MATERIAL AND METHODS: A prospective, endoscopist-blind, controlled trial. Sixteen patients (14F/2M; age: 57.06 +/- 10.16 yrs) with osteoarthritis (OA) on chronic therapy with NSAIDs underwent CE and upper gastrointestinal endoscopy (UGE). Seventeen patients with OA (9F/2M; age: 57.47 +/- 9.82 yrs) who did not take NSAIDs were included as a control group. A scale ranging from 0 to 2 (0 = no lesions, 1-minor = red spots or petechiae, denuded areas and/or 1-5 mucosal breaks; 2-major = > 5 mucosal breaks and/or strictures, or hemorrhage) was designed to assess the severity of small bowel mucosal injuries. RESULTS: CE found intestinal lesions in 75% (12/16) of patients in the study group and in 11.76% (2/17) of controls (p < 0.01). Seven out of 16 NSAID consumers (43.75%) and none in the control group (0%) had a major small bowel mucosal injury (p < 0.01). The percentages of patients with grade 1 and 2 gastroduodenopathy in the study group, as assessed by UGE, were 37.14 and 23.81%, respectively. There was no significant difference in the rate of major enteropathy between patients with none or minor gastroduodenal injury, and those with major gastroduodenopathy (43.75 vs. 40%; p = N.S.). CONCLUSIONS: Chronic NSAID intake is associated with a high rate of small bowel mucosal injuries. Our data have failed to demonstrate a relationship between the severity of gastroduodenal and intestinal injury.

OBJECTIVE: To assess the efficiency of endorectal ultrasound (ERUS) in the study of chronic idiopathic anal pain (CIAP). MATERIAL AND METHOD: This is a prospective and descriptive study in which 40 patients, 18 men and 22 women with an average of 47 years, were included. They had chronic anal pain of at least 3 months duration. A complete colonoscopy was performed in all patients, which found no abnormalities to explain clinical symptoms. Patients with anal fissure and internal hemorrhoids of any degree, perianal suppurative processes, and pelvic surgery were excluded from the study. An ALOKA ProSound SSD-4000 ultrasound console attached to a multifrequency radial transductor ASU-67 (7.5 and 10 MHz) was used. RESULTS: One patient could not tolerate the examination. In 8 patients (20% of cases) alterations were detected during ultrasonography: in 4 patients (10% of the cases; 1 man and 3 women) internal anal sphincter (IAS) hypertrophy, and in 5 patients (4 women and 1 man) a torn sphincter complex. A tear in the upper IAS canal and hypertrophy of the middle anal canal were observed in one patient (1 woman). CONCLUSIONS: ERUS is a simple, economic and useful test to study anorectal pathologies. Although in most studied cases no damage to the anal canal or rectal wall was detected, in a considerable number of patients we observed a thickening of the IAS, a probable cause of anal pain. Therefore, we understand that ERUS should be included in the study of CIAP.

Objetivo: evaluar el rendimiento de la ecografía rectoanal (ERA) en el estudio del dolor anal crónico idiopático (DACI). Material y método: se trata de un estudio prospectivo y descriptivo en el que se han incluido 40 pacientes, 18 hombres y 22 mujeres, con edad media de 47 años, con clínica de dolor anal crónico de al menos 3 meses de evolución. A todos los pacientes se les había realizado una colonoscopia completa, en la que no se encontró anomalía que justificara la clínica. Se excluyeron del estudio pacientes con fisura anal y con hemorroides internas de cualquier grado, enfermedad supurativa perianal y cirugía pélvica. Se utilizó un ecógrafo ALOKA ProSound SSD-4000 al que se conectó un transductor radial multifrecuencia ASU-67 (7,5 y 10 MHz). Resultados: un paciente no toleró la exploración. En 8 pacientes (20% de los casos estudiados) se detectaron alteraciones en el estudio ecográfico: en 4 pacientes, 10% de los casos (1 hombre y 3 mujeres), hipertrofia del esfínter anal interno (EAI) y en 5 pacientes (4 mujeres y 1 hombre) rotura del complejo esfinteriano. En una mujer se observó rotura de EAI en canal alto e hipertrofia del mismo en el canal medio. Conclusiones: la ecografía rectoanal es una prueba sencilla, económica y útil para el estudio de la patología rectoanal. Si bien, en la mayoría de los casos estudiados no se han detectado lesiones en el canal anal ni en la pared rectal, en un porcentaje no desdeñable de pacientes hemos observado engrosamiento del EAI, que podría considerarse posible causa del dolor anal. Por tanto, consideramos que la ecografía rectoanal debe ser incluida en el estudio del dolor anal crónico idiopático(AU)

Chronic abdominal pain is highly prevalent in school-aged children and is one of the most frequent disorders in our environment. The aim of the present study was to evaluate the usefulness of capsule endoscopy (CE) in patients with chronic abdominal pain. Sixteen patients (nine boys and seven girls), aged between 5 and 16 years old, with chronic abdominal pain for at least 12 months were studied. In all patients the results of hemograms, biochemical investigations, urine sediment test, Helicobacter pylori breath test and celiac serology were normal. In all children, gastroscopy, small bowel follow-through, abdominal ultrasound and colonoscopy were normal. All patients received CE by mouth. In 43.75 % of the patients studied (7/16), the capsule showed evidence of nodular lymphoid hyperplasia, mainly located in the ileum. In one girl, oxyuriasis was observed in the cecum and in another girl aphthous lesions were observed in the ileum. These lesions suggested small bowel Crohn's disease. CE mainly showed images compatible with nodular lymphoid hyperplasia, with unknown clinical significance. Consequently, we conclude that CE does not provide useful information in patients with abdominal pain without other symptoms.

BACKGROUND AND OBJECTIVES: The diagnostic yield of push enteroscopy (PE) varies widely from 13 to 78% of cases, according to the various series. The aim of this retrospective cohort study was to determine the endoscopic and histological yield of PE in our health area. PATIENTS AND METHODS: A total of 355 consecutive patients (190 males/165 females; mean age 45 years, range 15-89) underwent PE over a 6-year period, from 1997 to 2003. PE was performed under sedation and without overtube. Small-bowel mucosa biopsies were taken in 199 explorations (56%). Clinical indications for PE included: chronic diarrhea (35%), occult digestive bleeding (ODB) or iron-deficiency anemia (28%), suspected small-bowel malignancy (16%), chronic abdominal pain (28/355; 8%), follow-up of polyposis or malabsorption syndromes (7%), and abnormal radiographic findings (6%). RESULTS: PE detected lesions in 122 cases (34%); in 6 cases (6%) lesions were within the reach of esophagogastroduodenoscopy. A normal macroscopic appearance of the small intestinal mucosa with an abnormal histological study was seen in 16 patients (6%). Major findings included: malabsorptive diseases (14%), nonspecific enteropathy (5%), angiodysplasia (3,5%), lymphangiectasia (3%); jejunal polyps (2%), Crohn s disease (2%), intestinal tumors (2%), extrinsic jejunal strictures (0.5%), and other (10/355; 3%). Abnormal radiographic findings (62%), chronic diarrhea (37%) and ODB (31%) were the indications with a higher diagnostic yield. No major complications were seen. CONCLUSIONS: According to our experience, PE is a safe and useful tool for the evaluation of small-bowel disease, especially in some indications (abnormal radiographic findings, chronic diarrhea, and ODB). Small-bowel biopsy increases PE's diagnostic yield in patients with chronic diarrhea.
