Colonoscopy quality assessment.

AIM: Colonoscopy has become accepted as the most effective method for colon exploration. Some application problems have been detected in the setting of normal clinical care due to its wide range of uses in recent years, and therefore there is a need to measure colonoscopy quality. For that purpose valid quality indicators are necessary to be defined. The application process of some quality indicators is presented in this study. The proposed indicators in this study are: quality of bowel preparation, cecal intubation rate, withdrawal time, adenoma detection rate, and adenoma removal rate. MATERIAL AND METHOD: This is a prospective 12-month study where colonoscopies performed in the VI health area of Murcia Region were evaluated. From February 2006 to February 2007 a total of 609 subjects were eligible for colonoscopy after a positive fecal blood test in the setting of a colorectal cancer screening program. A sample of thirty patients (n: 30) was considered representative to assess the reliability of quality indicators and for a preliminary analysis of results. RESULTS: Indicators results are: quality of bowel preparation (87%), kappa 0.74 (95% CI: 0.48-0.99); cecal intubation rate (90%) 0.74 (95% CI: 0.49-0.99); adenoma detection and removal rate (96%), kappa: 0.78 (95% CI: 0.53-0.99); withdrawal time: 13.36 min (95% CI: 10.48-16.11). Kappa: 0.78 (95% CI: 0.49-0.99). CONCLUSIONS: Quality indicators definition and application in colonoscopy performance is possible. More studies are necessary to define the role of these indicators in the setting of clinical practice.

Double-balloon enteroscopy: a descriptive study of 50 explorations.

AIM: To evaluate the utility of double-balloon enteroscopy for small-bowel disease. DESIGN: A prospective study of 50 consecutive enteroscopies performed from December 2004 to July 2005 to analyze diagnoses and treatments. PATIENTS: 44 patients (33 had undergone a previous capsule endoscopy) with indications for obscure digestive hemorrhage, angiodysplasia, Peutz-Jeghers syndrome, ulcer, suspected Crohn's disease, tumors, and refractory celiac disease. RESULTS: We carried out enteroscopy studies in 44 patients by the oral route and, in 6 additional patients, by both the oral and anal routes. We reached the ileon with the oral route in all cases but one (jejunal stenosis), and in 4 cases out of 7 with the anal route, with an average duration of 73 minutes. We found angiodysplasia in 19 cases, as well as NSAID-related enteropathy, Crohn's disease, diverticulosis, and Waldenström's disease. We performed biopsies in 31% of cases with diagnoses of adenocarcinoma, lymphangiectasia secondary to tumor in celiac disease, and Whipple's disease. We treated 19 patients with angiodysplasia (1 to 20 synchronous lesions) with argon, and 4 patients with polyps using polipectomy (sporadic polyps or Peutz-Jeghers syndrome). A retained capsule in one patient with stenosis was removed. CONCLUSIONS: Double-balloon enteroscopy is a useful and effective technique in the diagnosis and treatment of small intestine diseases, thus complementing capsule endoscopy. More studies are needed to analyze its impact on the management of this condition.

[Quality of life of cirrhotic patients before and after liver transplantation]. / Calidad de vida de pacientes cirróticos antes y después del trasplante hepático.

In this study we assessed the quality of life of a group of cirrhotic patients who underwent liver transplant using a psychological test to evaluate family relations, work activity, emotional state and social relations. The quantification of hospital dependence and degree of fitness for work, before and after the transplant were also analyzed. 32 patients were included in the study with the diagnosis of hepatic cirrhosis and minimum post-transplant follow-up of 6 months. The average age of the study population was 44.8 +/- 10.5 years; there were 23 males and 9 females, with an average follow-up of 15 months. The psychological test used was the Quality of Life Scale (QLS), which consists of 21 items, each scoring from 1 to 6 points. The questionnaire was completed before the transplant by all the patients, and after the transplant by 32 patients at 6 months, 20 at 12 months and 12 at 24 months. Hospital dependence was evaluated by number of admissions and number of days per admission. Lastly, we compare the rate of unfitness for work before the transplant and at one and two years after the transplant. The QLS test showed a post-transplant improvement in the 4 aspects assessed, specially in the personal aspects (emotions and family) (p < 0.001). Hospital dependence following pre-transplant situation (p < 0.01). Finally, the post-transplant percentage of unfitness for work decreased with time, reaching significant differences 2 years after the liver transplant (p < 0.05).

Chronic intracerebral haematoma.

Chronic intracerebral haematoma is a rare entity. The natural history of this condition is unclear and its diagnosis is difficult. Two cases of chronic intracerebral haematoma from different sources are reported. We discuss the controversies about its pathogenesis, clinical presentation, CT diagnosis and treatment.

Hepatitis C in liver transplant patients.

The aim of this study was to determine whether infection by the hepatitis C virus (HCV) recurs after orthotopic liver transplantation (OLT) and to define the natural history of post-transplantation chronic hepatitis due to HCV. Of 70 patients, 10 (14.3%) were found to have antibodies to HCV before transplantation. After OLT 14 of the 70 patients (20%) had positive anti-HCV antibodies: 8 of 10 positive pre-OLT (80%) and 6 of 60 negative pre-OLT (10%). Of 14 patients anti-HCV+ post-OLT (57%), developed 8 chronic hepatitis: chronic persistent hepatitis in three patients, chronic lobular hepatitis in three patients and chronic, active hepatitis in two patients. We treated four patients with interferon obtaining normalization of transaminases in three of them after 6 months, but with a severe relapse in two. These results suggest that hepatitis C recurs in a majority, of liver transplant recipients and that morbidity is an important consideration. Interferon treatment of these patients requires further study to obtain conclusive results.

Enteroscopia de doble balón: estudio descriptivo de 50 exploraciones / Double-balloon enteroscopy: a descriptive study of 50 explorations

Objetivo: valorar la utilidad de la enteroscopia de doble balón en enfermedades de intestino delgado. Diseño: estudio prospectivo descriptivo de 50 enteroscopias consecutivas (diciembre 2004 a julio 2005), analizando diagnóstico y terapéutica. Pacientes: cuarenta y cuatro pacientes (33 con cápsula endoscópica previa) con hemorragia digestiva oculta o lesiones detectadas mediante cápsula (angiodisplasias, pólipos, úlceras, enfermedad de Crohn, celiaca refractaria y tumores). Resultados: se realizó enteroscopia vía oral a 44 pacientes y vía oral más anal a 6. Por vía oral se progresó hasta íleon en todos los casos excepto uno (estenosis yeyunal), por vía anal en 4 de 7 (3 casos con dificultad de paso por Bahuin). La duración media fue 73 minutos. Se detectaron angiodisplasias (19 casos), úlceras en enteropatía por AINE, enfermedad de Crohn, enfermedad de Waldenström, y divertículos. Se realizaron biopsias en yeyuno-íleon en un tercio de los casos (adenocarcinoma, linfangiectasias secundarias a tumor sobre celíaca, enfermedad de Whipple). Se realizó terapéutica con argón a 19 pacientes con angiodisplasias (1 a 20 lesiones), polipectomía a 4 pacientes con pólipos esporádicos o Peutz Jeghers (1 a 15 pólipos) y se extrajo una cápsula endoscópica retenida en una estenosis. Conclusiones: la enteroscopia de doble balón es una técnica útil y eficaz en el diagnóstico y tratamiento de las lesiones del intestino delgado, complementando a la cápsula endoscópica. Hacen falta más estudios para analizar el impacto esperado en el cambio del manejo de estos pacientes
