[Factors related to a suboptimal bowel preparation for colonoscopy]. / Factores relacionados a una subóptima preparación intestinal para la colonoscopía.

INTRODUCTION: Colonoscopy is the standard method for the evaluation of the colon. A suitable intestinal cleaning is critical for the effectiveness and security of the procedure, but unfortunately there is a high proportion of suboptimal bowel preparation. OBJECTIVE: To identify factors related to suboptimal bowel preparation. METHODS: We performed an analytic, observational, cross-sectional and prospective study. We included all outpatients scheduled for colonoscopy in the Peruvian-Japanese Health Center between January and July 2012. We excluded patients with a complete or partial colonic resection. In patients with two or more colonoscopies during the study interval, only the first procedure was considered. Aronchick scale was used in assessment of bowel cleaning. The variables studied with relationship to bowel preparation were: age, sex, grade ofeducation, body mass index, time of examination, history (diabetes mellitus, stroke, cirrhosis, use of antidepressants/anxiolytics, number of bowel movements per week, abdominal surgery, personal history of previous colonoscopy, polyps and colon cancer, family history of colon cancer), received purgative, additional laxative, indication for colonoscopy and adverse effects of the preparation. Statistical analysis was made with SPSS v.160. For the categorical variables we used chi square test or Fisher exact test, whereas for continuous variables the Mann Whitney test was used. The variables significantly associated with suboptimal preparation in the univariated analysis were included in a multivariate analysis using logistic regression. RESULTS: We included 841 patients. The bowel preparation was suboptimal in 438 patients (52.1%). The univariate analysis showed that the factors related to suboptimal preparation were age (P = 0.023) and body mass index ≥ 30 kg/m2 (P = 0.021). The multivariate analysis confirmed that age ≥ 70 years old (P = 0.001) and body mass index ≥ 30 kg/m2 (P = 0.010) were the variables related to suboptimal bowel preparation. CONCLUSIONS: Age greater than 70 years old and obesity are factors related to suboptimal bowel preparation.

[Quality indicators for colonoscopy in the Peruvian Japanese Policlinic: linked factors]. / Indicadores de calidad en colonoscopía en el Policlínico Peruano Japonés: factores relacionados.

INTRODUCTION: Colonoscopy is the gold standard for the diagnosis of diseases of the colon and rectum and the primary prevention test for colon cancer. The main indicators of quality in colonoscopy are the rate of complete colonoscopy and the rate of detected adenomas. OBJECTIVES: We aimed to know the rates of cecal intubation and detection of adenomas and to identify factors related to these two quality indicators in colonoscopies performed in the Peruvian Japanese Policlinic during 2007. MATERIAL AND METHODS: A correlational cross-sectional and retrospective study was performed. Data were collected from the colonoscopies performed by 10 endoscopists in the Peruvian Japanese Policlinic during 2007. RESULTS: We included 843 colonoscopies. Cecal intubation was achieved in 801 patients (95%). The multivariate analysis found that cecal intubation was correlated with the type of sedation/analgesia and the quality of bowel preparation. At least one adenoma was detected in 168 colonoscopies (19.9%). Multivariate analysis found that age, colonic cleansing and time of withdrawal were factors significantly associated with the detection of adenomas. CONCLUSIONS: The quality of colonoscopy depends on several factors: bowel preparation, type of sedation/analgesia and time of withdrawal. These are the targets on which we can act to improve performance.

[Sedation used during colonoscopies at the Peruvian-Japanese policlinic. Their relationship with quality indicators]. / Sedación Utilizada en las Colonoscopías en el Policlínico Peruano Japonés y su Relación con Indicadores de Calidad.

INTRODUCTION: The practice of sedation used during colonoscopy vary widely between countries, even gastroenterologists and endoscopy centers. Knowing the type of sedation used at present and its relationship to quality indicators of colonoscopy, will help improve the quality of it. OBJECTIVES: To determine the type of sedation used for colonoscopies in the Japanese Peruvian Polyclinic, and its relation to quality indicators in colonoscopy: cecal intubation rate and detection rate of adenomas MATERIAL AND METHODS: A retrospective cross-sectional correlational. Data were recorded colonoscopies performed in the Japanese Peruvian Polyclinic during 2007, which were conducted by 10 endoscopists RESULTS: We included 843 colonoscopies, of which 63.1% received moderate sedation, deep sedation, 36.7% and only 0.2% received no sedation. Moderate sedation was performed most commonly with the combination midazolam + meperidine, whereas deep sedation propofol used almost exclusively in combination with other agents. An anesthesiologist was present in 38.4% of the colonoscopies. Statistical analysis showed significant differences in cecal intubation rate when deep sedation was used: 96.1% compared to the moderate: 94.5% (p = 0.009). Equally significant difference in adenoma detection rate with deep sedation, 26.9%, compared with the moderate: 15.8% (p = 0.000). Immediate complications were reported in 9% of procedures was more common when deep sedation was used: 13.3% compared to the moderate: 6.4% (p = 0.003). CONCLUSIONS: The moderate sedation was the most common method of sedation used for colonoscopies in the Japanese Peruvian Polyclinic. Deep sedation was associated with higher rates of cecal intubation and adenoma detection, but also in more immediate complications. KEYWORDS: sedation, colonoscopy, colonoscopy quality.

Edad óptima para el despistaje endoscópico de cáncer gástrico en pacientes con dispepsia sin síntomas de alarma / Age optimal for endoscopic screening for gastric cancer in patients with dyspepsia symptoms without alarm

Objetivo: Determinar la edad óptima de despistaje de cáncer gástrico en pacientes con dispepsia sin síntomas de alarma. MÉTODO: Estudio analítico, descriptivo y retrospectivo (2001-2005). Se analizó 285 casos de pacientes con dispepsia y cáncer gástrico en el Hospital Nacional Arzobispo Loayza, calculándose la frecuencia acumulativa por edad y grupo etáreo, así como también por estudio de percentiles, para determinar la edad óptima de despistaje endoscópico. Ambos grupos, con y sin signos de alarma fueron analizados con frecuencias relativas y absolutas, Chi-cuadrado y test de Student según la variable categórica o contínua respectivamente. Se consideró valores significativos de p<0.05. RESULTADOS: De 32,388 endoscopías realizadas en pacientes por motivo de dispepsia, se encontró 285 casos confirmados de cáncer gástrico, 45 de ellos sin signos de alarma. No hubo diferencia en la frecuencia acumulativa <35 y <40 años, con una pérdida de casos de cáncer gástrico de 0.29 y 0.30 por 1000 endoscopías, respectivamente. Al tomarse 40 años como edad óptima de despistaje, se perderían 4 casos (8.9 por ciento, aproximadamente 1 caso por año), de los cuales uno sería cáncer gástrico precoz. El percentil 5 fue 30.3 años y el 10 fue 39,4 años. Si se hubiera tomado una edad de 45 años se habrían perdido 6 casos (15 por ciento) y 12 (27 por ciento), si la edad se elevaba a 55 años. No hubo diferencia estadísticamente significativa entre el sexo, edad y duración de la dispepsia. Por el contrario, sí existió relación con el tipo de dispepsia (ulcerosa), tipo de lesión, localización, histología y el estadío del cáncer gástrico para ambos grupos. CONCLUSIÓN: Se recomienda que la edad óptima para el despistaje endoscópico de cáncer gástrico en pacientes con dispepsia sin síntomas de alarma, sea a partir de los 40 años de edad para ambos sexos.

Objective: To determine the optimal age for screening endoscopy on patients withdyspepsia without alarm symptoms to avoid missing gastric cancer. Methods: A Cross sectional study was performed (2001-2005). 285 cases of patientswith dyspepsia and gastric cancer were found at Arzobispo Loayza National Hospital. Cumulative age frequencies and percentiles were used to determine the optimal age for screening endoscopy. Both groups, with and without alarm symptoms were comparedusing the chi-square test for categorical data. Continuous data was expressed as mean (SD) and was compared with the t- test. Significant values of p were specified as mayor 0.05. Results: A total of 32,388 upper endoscopic procedures in dyspeptic patients were performed and 285 cases of gastric cancer were diagnosed, 45 cases of them not featuring any alarm symptoms were found. There were no differences in cumulative frequency between the mayor 35 and mayor 40 years old, with a frequency of 0.29 and 0.20 per 1000 endoscopies, respectively. If the age of 40 had been taken as the optimal age for screening, 4 cases of gastric cancer (8.9 per cent) would have been missed (one case per year approximately),one case would have been an early gastric cancer. The 5th percentile was 30.3 years old and the 10th was 39.4. If the age of 45 had been taken as the optimal age for screening, 6 (15 per cent) cases of gastric cancer would have been missed and 12 (27 per cent) cases if the age was 55 years old. There was no statistical difference between gender, age and duration of dyspepsia. On the other hand, relations between type of dyspepsia (ulcerative), type of lesion, position, histology and stage of gastric cancer for both groups were found. Conclusion: It´s recommended that the optimal age for endoscopic screening for gastric cancer in dyspeptic patients without alarm symptoms for both genders, should be over 40 years old.

Cáncer gástrico incipiente / Early gastric cancer

Se presenta un trabajo de revisión sobre cáncer gástrico incipiente, iniciándose con una recopilación de los hechos importantes que permitieron el avance en el diagnóstico y tratamiento. Se señala la definición y clasificación de la escuela Japonesa. Se revisan los trabajos importantes descritos en el Japón y otros países con los reportado en el Perú, señalándose la distribución por edad, la sintomatología clínica, las formas más frecuentes en el diagnóstico, las características diferenciales con otras lesiones y la proporción entre cáncer gástrico incipiente y avanzado, observándose que mientras en el Japón existe un incremento progresivo en los años sucesivos que llega a más del 50% de los casos; en Perú no hay un incremento significativo, a pesar de la difusión de conocimientos y mejor equipamiento. Se analizan los factores que retardan el diagnóstico y se expone una estrategia que posibilite el incremento del diagnóstico del cáncer gástrico incipiente en el que se propone la conducta a seguir con el paciente sintomático y en los que se diagnostica lesión elevada o erosiva ulcerativa y en los que se consideran dentro del grupo de riesgo.

This is a work of revision on Early Gastric Cancer, begins with a compilation of significant event that allowed advances in diagnostic and treatment. This paper presents the definition and classification of the Japanese School. The work makes a review of the most important studies made in Japan and other countries and compares them with Peruvian works, denoting the incidence by ages, the clinic symtomalogy, the most usual forms in diagnostic, the characteristic that makes the difference between cancer and other lesions, besides presents the proportion between early and advanced gastric cancer and observing that while in Japan exists a progressive increase in the following years over coming 50% of the cases, in Peru there is no a significant increase, in spite of the knowledge divulging and better equipment. The woks analyses the determining factors in diagnostic dalay and finally, this study presents a strategy that facilitates the early gastric cancer diagnostic, putting up for discussion a course of treatment to the symptomatic patient and besides the strategy must to diagnostic elevated or erosive ulcus lesion in the risk group patient.
