[Knowledge and quality of life in chronic kidney disease and peritoneal dialysis]. / Conocimiento y calidad de vida en enfermedad renal crónica y diálisis peritoneal.

Background: Knowledge of one's own chronic kidney disease (CKD) can improve long-term quality of life (QoL). Peritoneal dialysis presents with residual symptoms that reduce the QoL. Objective: To correlate knowledge of the disease and QoL in patients with CKD and on continuous ambulatory peritoneal dialysis (CAPD). Material and methods: A descriptive, cross-sectional, and prospective study was carried out in patients with CKD treated at a second-level hospital of the Mexican Institute for Social Security (Instituto Mexicano del Seguro Social) in Puebla. SF-36 and KiKS questionnaires were applied. Age, sex, education, marital status, perception of QoL, and level of knowledge were recorded. Descriptive statistics and Spearman's coefficient were used. Results: 199 patients with CKD in CAPD were included, 62.8% women, minimum age range was 18 to 20 years with 4% and maximum of 61 years or more with 49.2%, 35.6% of patients completed primary school, and 65.3% were married. The most frequent comorbidity was diabetes (57.2%). The least affected QoL domain was pain. KiKS recorded a mean of 0.54 (regular knowledge about the disease). It was recorded a weak and significant correlation in the QoL domains: physical health, physical role, pain, general health, mental health (p ≤ 0.05). Conclusions: There is a significant but weak correlation between the perception of QoL and the level of knowledge of the disease in CKD patients with CAPD.

Introducción: el conocimiento adecuado de la enfermedad renal crónica (ERC) puede mejorar la calidad de vida (CV) a largo plazo. La diálisis peritoneal cursa con síntomas residuales que reducen la CV. Objetivo: correlacionar el conocimiento de la enfermedad y la CV en pacientes con ERC y en diálisis peritoneal continua ambulatoria (DPCA). Material y métodos: se llevó a cabo un estudio descriptivo, transversal y prospectivo en pacientes con ERC atendidos en un hospital de segundo nivel de atención del Instituto Mexicano del Seguro Social (IMSS) en Puebla. Se les aplicaron los cuestionarios SF-36 y KiKS. Se registró edad, sexo, escolaridad, estado civil, percepción de calidad de vida, nivel de conocimiento. Se utilizó estadística descriptiva y coeficiente de Spearman. Resultados: se incluyeron 199 pacientes con ERC en DPCA, 62.8% mujeres, edad mínima de 18 a 20 años (4%) y máxima 61 años o más (49.2%), 35.6% de los pacientes cursó primaria completa, y 65.3% estaban casados. La comorbilidad más frecuente fue diabetes (57.2%). El dominio de CV menos afectado fue el dolor. El KiKS registró una media de 0.54 (conocimiento regular sobre la enfermedad). Se registró una correlación débil y significativa en los dominios de CV: salud física, rol físico, dolor, salud general, salud mental (p ≤ 0.05). Conclusiones: existe una correlación significativa pero débil entre la percepción de la CV y el nivel de conocimiento de la enfermedad en los pacientes con ERC con DPCA.

Addressing the unmet needs of women with breast cancer in Mexico: a non-randomised pilot study of the digital ePRO intervention.

OBJECTIVES: This study aimed to explore the acceptability, feasibility, usability, and preliminary effect of an electronic patient-reported outcome (ePRO) intervention for patients with breast cancer in Mexico. DESIGN: We conducted a multimethod non-randomised pilot study. We used a pre-test/post-test design for quantitative assessment of the intervention's effect on patients' supportive care needs and quality of life. We conducted in-depth interviews (IDIs) with participants and healthcare workers to explore the intervention's benefits and barriers and understand its feasibility. PARTICIPANTS: 50 women aged 20-75 diagnosed with stage I-III breast cancer were enrolled within 2 weeks of starting neoadjuvant or adjuvant treatment with chemotherapy or radiotherapy. We excluded illiterate women and those with visual impairment, cognitive disability or severe depression. IDIs were conducted with 18 participants and 10 healthcare providers. SETTING: Oncology services in three public hospitals of the Mexican Social Security Institute. INTERVENTION: The ePRO intervention consisted of a responsive web application for weekly symptom reporting combined with proactive follow-up by nurses guided by predefined clinical algorithms for 6 weeks. RESULTS: 50 women were enrolled out of 66 eligible patients approached (75.8%). All 50 completed the 4-week follow-up assessment (100% retention). Completion of the symptom registry declined from 100% in week 1 to 66% in week 6. Participants experienced decreases in supportive care needs and increased quality of life. The ePRO application was rated highly usable. Participants and health professionals both perceived intervention benefits. Drawbacks included poor fit for women receiving radiotherapy and challenges using the application for women with low digital literacy or experiencing severe symptoms. CONCLUSIONS: This pilot study provided evidence of the high usability and potential efficacy of a web-based ePRO intervention. We revised recruitment during the pilot to include multiple facilities, and we will further revise for the randomised trial to address barriers to successful ePRO implementation. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov ID: NCT05925257.

Implementation of a roadmap for the comprehensive diagnosis, follow-up, and research of childhood leukemias in vulnerable regions of Mexico: results from the PRONAII Strategy.

The main objective of the National Project for Research and Incidence of Childhood Leukemias is to reduce early mortality rates for these neoplasms in the vulnerable regions of Mexico. This project was conducted in the states of Oaxaca, Puebla, and Tlaxcala. A key strategy of the project is the implementation of an effective roadmap to ensure that leukemia patients are the target of maximum benefit of interdisciplinary collaboration between researchers, clinicians, surveyors, and laboratories. This strategy guarantees the comprehensive management of diagnosis and follow-up samples of pediatric patients with leukemia, centralizing, managing, and analyzing the information collected. Additionally, it allows for a precise diagnosis and monitoring of the disease through immunophenotype and measurable residual disease (MRD) studies, enhancing research and supporting informed clinical decisions for the first time in these regions through a population-based study. This initiative has significantly improved the diagnostic capacity of leukemia in girls, boys, and adolescents in the regions of Oaxaca, Puebla, and Tlaxcala, providing comprehensive, high-quality care with full coverage in the region. Likewise, it has strengthened collaboration between health institutions, researchers, and professionals in the sector, which contributes to reducing the impact of the disease on the community.

Correlación del resultado histopatológico y hallazgos tomográficos en pacientes con lesiones hepáticas sospechosas de malignidad / Correlation of histopathological results and tomographic findings in patients with liver lesions suspicious for malignancy

RESUMEN Introducción: El cáncer hepático es la séptima neoplasia más frecuente a nivel mundial y la segunda causa de mortalidad asociada directamente a cáncer. En México presenta una incidencia del 3.9% en toda la población. A pesar de que la tomografía axial computada es el estudio diagnóstico inicial de elección, el diagnóstico final se establece con el estudio anatomopatológico de la lesión. Objetivo: Correlacionar los hallazgos tomográficos con el resultado histopatológico en pacientes con lesiones hepáticas con sospecha de malignidad, a los que se les tomó biopsia dirigida por USG. Material y métodos: Estudio descriptivo, de correlación, retrolectivo, homodémico y unicéntrico. El tiempo de estudio fue de septiembre 2021 a febrero 2022. Se seleccionó a pacientes mayores de 18 años con lesiones hepáticas sospechosas de malignidad, a los que se les realizó tomografía y biopsia guiada por ultrasonido. Se utilizó pruebas de Shapiro-Wilk (de normalidad) y se utilizó ꭕ2 para un análisis de asociación de variables categóricas. Resultados: Se incluyeron a 24 pacientes, a los cuales se les realizó tomografía y biopsia de lesión, encontrando un tamaño promedio de las lesiones de 2.39cm. Los resultados de la correlación entre el diagnóstico tomográfico y el diagnóstico histopatológico definitivo no tuvieron significancia estadística p=0.069. Conclusiones: No se encontró correlación significativa entre el estudio histopatológico y los hallazgos tomográficos en lesiones hepáticas sugerentes de malignidad.

ABSTRACT Introduction: Liver cancer is the seventh most common neoplasm worldwide and the second cause of mortality directly associated with cancer. In Mexico it has an incidence of 3.9% in the entire population. Although computed tomography (CT) is the imaging study of choice, the final diagnosis is established with the anatomopathological study of the lesion. Objective: Correlate the tomographic findings with the histopathological result in patients with liver lesions with suspicion of malignancy, who underwent USG-guided biopsy. Methods: Descriptive, correlation, retrolective, homodemographic and single-center study. The study period was from September 2021 to February 2022. Patients older than 18 years with liver lesions suspicious of malignancy were selected and underwent Computed Axial Tomography and ultrasound-guided biopsy. Shapiro Wilk tests (for normality) were used and chi-square was used for an analysis of association of categorical variables. Results: Twenty-four patients were included, who underwent Tomography and lesion biopsy, finding an average size of lesions of 2.39cm. The results of the correlation between the tomographic diagnosis and the definitive histopathological diagnosis did not have statistical significance p=0.069. Conclusions: No significant correlation was found between the histopathological study and tomographic findings in liver lesions suggestive of malignancy.

Embarazo pretérmino intrabdominal exitoso: Reporte de caso / Successful intrabdominal preterm pregnancy: A case report

RESUMEN Introducción: El embarazo ectópico es toda gestación, en la que el sitio de implantación del óvulo fecundado se localiza fuera de la cavidad endometria y representa el 1.4 % de estos. Caso clínico: Paciente de 28 años con dos cesáreas previas, sometida a salpingoclasia durante la última intervención. La paciente ingresó al hospital con presión arterial de 180/130 mm Hg, no respondió a tratamiento médico y presentó falla en la progresión de trabajo de parto, por lo que se decidió interrupción por operación cesárea. Durante la cirugía, se observó un pequeño útero con embarazo extrauterino adherido a la serosa del ciego, el colon ascendente y el apéndice. Se obtuvo un producto femenino pretérmino vivo; la madre cursó con evolución favorable y sin complicaciones posoperatorias. Conclusión: La presentación del embarazo abdominal ectópico es rara, por lo que un control prenatal adecuado por personal capacitado puede orientar a la sospecha diagnóstica. La madre y la recién nacida no presentaron ninguna complicación, a pesar de ser un embarazo abdominal avanzado y la inserción multifocal de la placenta. Se resalta la importancia del manejo oportuno y multidisciplinario cuando se enfrentan embarazos con curso anormal para la mejor evolución de la madre y del producto.

ABSTRACT Introduction: Ectopic pregnancy is any gestation in which the implantation site of the fertilized egg is located outside the endometrial cavity. Abdominal ectopic pregnancy represents 1.4% of these. Case report: 28-year-old patient with two previous cesarean sections; bilateral tubal obstruction during the last operation. The patient was admitted to the hospital with blood pressure of 180/130 mm Hg that did not respond to medical treatment and not progression to labor so it was decided to interrupt the pregnancy by cesarean section. During surgery, a small uterus with extrauterine pregnancy was observed adhered to the serosa of the cecum, ascending colon, and appendix. A live preterm female product was obtained; the mother had a favorable evolution and no postoperative complications. Conclusion: Ectopic pregnancies are rera. An adequate prenatal control by well trained personnel is essential for an accurate diagnosis. The mother and the newborn did not present any complication. It is very important to have and accurate an opportune diagnosis so trained personnel can offer an adequate management.

Galectin-9 Expression is Correlated to Cervical Squamous Cell Carcinoma Progression and Overall Survival.

Purpose: To determine whether galectin-9 gene (LGALS9) expression is correlated with cervical cancer progression, clinicopathological characteristics, and overall survival. To determine the biological processes and the abundance of tumour infiltrating immune cells related to the expression of LGALS9. Patients and Methods: The study was conducted in two phases: 1) The expression level of LGALS9 was determined using the data of 193 squamous cell carcinoma (SCC) samples from The Cancer Genome Atlas (TCGA) database. Biological processes and tumour infiltrating cells associated to LGALS9 expression were evaluated using gene set enrichment analysis (GSEA) and tumour immune estimation resource (TIMER). 2) Independently, galectin-9 was identified in 40 SCC samples by immunohistochemistry and optical density quantified using ImagePro® software. Results: The LGALS9 gene showed increased expression in cervical cancer samples. A higher expression level in SCC was related to better overall survival and to early clinical stages. GSEA showed that tumours with higher expression of LGALS9 were enriched in immune pathways such as interferon_alpha_response, and complement, the analysis of TIMER database showed a positive correlation between the expression level of LGALS9 and the abundance of tumour infiltrating immune cells. In addition, higher expression of galectin-9 was found in biopsies of SCC patients at early clinical stages, showing a trend of better survival. Conclusion: Higher expression levels of LGALS9 and galectin-9 in SCC were related to early clinical stages and better prognosis. GSEA and TIMER analysis suggested that galectin-9 could play an antitumor role in cervical SCC.

Timely radiographic detection of developmental dysplasia of the hip in family medicine residents. Educative intervention.

BACKGROUND: Developmental dysplasia of the hip (DDH) is a complex clinical entity that is usually underdiagnosed, if not detected and managed early, will turn the affected individual into a disabled being, with negative social, economic and emotional effects. OBJECTIVE: To determine the capacity for the timely radiographic detection of DDH before and after an educational intervention. METHOD: An educational intervention is carried out in family medicine resident, where they are given training on detection in DDH radiographic projections. Pre- and post-training evaluation is carried out. Statistical analysis is performed using Student's t and χ2, taking p ≤ 0.05 as significant. RESULTS: 94 residents participated. In the pre-intervention evaluation, 87.2% had no knowledge of the early detection protocol (p = 0.525). It was observed that 98.9% incorrectly drew the Perkins line (p = 0.427), 96.8% the Hilgenreiner line (p = 0.177) and 87.2% did not consider the data of bilateral dysplasia (p = 0.956). After the educational intervention, 87.2% correctly drew the Perkins line (p = 0.926), 97.8% the Hilgenreiner line (p = 0.325) and 78.7% if they considered the data of bilateral dysplasia (p = 0.826). CONCLUSIONS: After this training, 80% of family medicine residents were able to detect DDH in a timely manner.

ANTECEDENTES: La displasia del desarrollo de la cadera (DDC) constituye una entidad clínica compleja que suele ser infradiagnosticada que, de no ser precozmente detectadas y manejadas, convertirán al individuo afectado en un ser discapacitado, con efecto negativo social, económico y emocional.

Asociación entre parámetros hematológicos y fenotipos metabólicamente poco saludables en niños y adolescentes

Introducción: El síndrome metabólico se ha asociado con cambios en parámetros hematológicos (glóbulos rojos, plaquetas y leucocitos); se pueden utilizar para identificar sujetos en riesgo de fenotipos metabólicamente no saludables (MUP). Se investigó si estos parámetros hematológicos sirven como biomarcadores para distinguir el fenotipo metabólicamente sano (MHP) del MUP en niños y adolescentes. Métodos: Estudio transversal, 292 niños y adolescentes. El diagnóstico de MUP fue según consenso. Se utilizó ANOVA unidireccional en las comparaciones, regresión logística múltiple para determinar si el sexo, el grupo etario, el estado nutricional, la pubertad, los parámetros hematológicos y la resistencia a la insulina se asociaron con MUP. Resultados: Edad media 11 años (DE: 2,61). Los valores de RDW fueron significativamente más bajos en los niños en el grupo de peso normal metabólicamente insalubre (MUNW) en comparación con los niños con obesidad metabólicamente no saludable (MUO) (12,33 ± 0,90 vs. 13,67 ± 0,52; p = 0,01) y en la obesidad metabólicamente saludable (MHO) en comparación con el grupo MUO (13,15 ± 0,53 vs. 13,67 ± 0,52; p = 0,04). En adolescentes, la relación plaquetas/linfocitos fue mayor en el grupo MHNW (con un valor medio de 152,60 (DE 62,97) vs 111,16 (DE 44,12) para el grupo MHO. Al ajustar por edad, estado nutricional y pubertad, los índices hematológicos no se asociaron con MUP. Conclusión: Los parámetros hematológicos no están asociados independientemente con el MUP, y es poco probable que representen biomarcadores confiables para la detección del MUP en la población pediátrica.

Introduction: Metabolic syndrome has been associated with changes in several hematological parameters, such as red blood cells, platelets, and leucocytes. Therefore, hematologic parameters can be used to identify the subjects at risk of metabolically unhealthy phenotypes (MUP). The current study investigated if hematological parameters can serve as biomarkers to distinguish metabolically healthy phenotype (MHP) from MUP in children and adolescents. Methods: Two hundred ninety-two children and adolescents were enrolled in this cross-sectional study. The MUP was diagnosed using consensus-based criteria. Group comparisons were performed using one-way ANOVA. Multiple logistic regression analysis was used to determine if sex, age group, nutritional status, puberty, hematological parameters, and insulin resistance were associated with MUP. Results: The subject's age mean was 11 years (SD: 2.61). RDW values were significantly lower in children in the metabolically unhealthy normal weight (MUNW) group compared to children with metabolically unhealthy obesity (MUO) group (12.33 ± 0.90 vs. 13.67 ± 0.52; p = 0.01) and in metabolically healthy obesity (MHO) compared to MUO group (13.15 ± 0.53 vs. 13.67 ± 0.52; p = 0.04). In adolescents, the platelet-to-lymphocyte ratio was higher in the MHNW group, with a mean value of 152.60 (SD 62.97) compared to 111.16 (SD 44.12) for the MHO group. However, after adjusting for age, nutritional status, and puberty, hematological indices were not associated with MUP. Conclusions: The study demonstrates that hematologic parameters are not independently associated with the MUP, and it is unlikely that they represent reliable biomarkers for screening for the MUP in the pediatric population.

To compare physical, respiratory, cognitive and functional independence functional parameters in post-COVID-19 patients with respiratory sequelae before and after a respiratory physical and occupational therapy program. Methods. A comparative, quasi-experimental, prospective study was conducted in outpatients discharged from hospitalization for COVID-19 in a 3rd level of care Hospital of the Mexican Institute of Social Security in Puebla, Mexico during 2020-2021. Scales were applied before and after the rehabilitation program. Analytical statistics were used. Results. We included 116 patients, 57.7% men, mean age 47.32 years (min. 20, max. 79); 77 (66.3%) patients presented moderate symptoms in hospitalization. A significant p-value was obtained (p <0.001). Conclusion. Significant improvement is observed in post-COVID-19 patients after receiving respiratory physical and occupational therapy.

Donated Blood Screening for HIV, HCV and HBV by ID-NAT and the Residual Risk of Iatrogenic Transmission in a Tertiary Care Hospital Blood Bank in Puebla, Mexico.

Hepatitis C virus (HCV), human immunodeficiency virus (HIV) and hepatitis B virus (HBV) can be transmitted by blood transfusion. Most transmission occurs during the acute viremic phase (AVP), before antibody development. To reduce transmission risk, individual donor nucleic acid testing (ID-NAT) is used. In Puebla, Mexico, serological tests and ID-NAT have been applied to screen blood donors and detect individuals in AVP. In the present study, 106,125 blood donors' data in two periods (2012-2015 and 2017-2019) were analyzed. The residual risk (RR) values were calculated considering ID-NAT results. The RR for HIV was 14 in 1 million donations or 1 in 71,428, the RR for HVC was 6.8 in 1 million donations or 1 in 147,058 and, for HBV, it was 156 in 1 million donations, or 1 in 6410. Previously, it was predicted that the transmission RR of these viruses would be reduced in Mexico through better screening with NAT. The use of ID-NAT has, indeed, increased the safety of blood reserves for HIV and HCV. However, more research is needed to determine why the residual risk of HBV did not decrease as much over the study period. ID-NAT is an important complementary tool for blood donor screening that should be implemented.

[Cognition in medical residents with and without anxiety in a specialist training hospital]. / Cognición en médicos residentes con y sin ansiedad en un hospital formador de especialistas.

Background: The resident doctor plays an important role in people's health care. Objective: To compare the cognition of medical residents with/without anxiety in a specialist training hospital. Material and methods: Comparative, prospective, cross-sectional study. Medical residents of any grade and specialty were included, who signed informed consent. Those with a diagnosis of cognitive impairment were excluded, and who did not complete the tests were eliminated. AMAS-A test was applied to assess anxiety and NEUROPSI: Attention and memory test for cognitive characteristics. Mann-Whitney's U and Spearman's rho were used, p≤0.05 was considered significant. Results: 155 residents were evaluated, 55.5% men, mean age 32.4 years. Internal Medicine was the predominant specialty (25.2%). AMAS-A identified 94.19% residents with anxiety. NEUROPSI reported Attention and memory domain (38.7%) in normal classification, Memory (34.2%) in high normal, and Attention and executive functions (32.3%) in severe alteration as predominant assessments. Only Memory showed a significant difference between residents with and without anxiety (p=0.015). Attention and executive functions-Physiological anxiety (r=-0.21, p=0.009) and Attention and memory-Social concern (r=-0.268, p=0.001) correlations were significant. Conclusions: The percentage of anxiety and cognitive alterations in residents physicians is high. Anxiety decisively affects memory capacity in these medical doctors.

Pictograms to assess bloating and distension symptoms in the general population in Mexico: Results of The Rome Foundation Global Epidemiology Study.

BACKGROUND: There is no term for bloating in Spanish and distension is a very technical word. "Inflammation"/"swelling" are the most frequently used expressions for bloating/distension in Mexico, and pictograms are more effective than verbal descriptors (VDs) for bloating/distension in general GI and Rome III-IBS patients. However, their effectiveness in the general population and in subjects with Rome IV-DGBI is unknown. We analyzed the use of pictograms for assessing bloating/distension in the general population in Mexico. METHODS: The Rome Foundation Global Epidemiology Study (RFGES) in Mexico (n = 2001) included questions about the presence of VDs "inflammation"/"swelling" and abdominal distension, their comprehension, and pictograms (normal, bloating, distension, both). We compared the pictograms with the Rome IV question about the frequency of experiencing bloating/distension, and with the VDs. KEY RESULTS: "Inflammation"/"swelling" was reported by 51.5% and distension by 23.8% of the entire study population; while 1.2% and 25.3% did not comprehend "Inflammation"/"swelling" or distension, respectively. Subjects without (31.8%) or not comprehending "inflammation"/"swelling"/distension (68.4%) reported bloating/distension by pictograms. Bloating and/or distension by the pictograms were much more frequent in those with DGBI: 38.3% (95%CI: 31.7-44.9) vs. without: 14.5% (12.0-17.0); and in subjects with distension by VDs: 29.4% (25.4-33.3) vs. without: 17.2% (14.9-19.5). Among subjects with bowel disorders, those with IBS reported bloating/distension by pictograms the most (93.8%) and those with functional diarrhea the least (71.4%). CONCLUSIONS & INFERENCES: Pictograms are more effective than VDs for assessing the presence of bloating/distension in Spanish Mexico. Therefore, they should be used to study these symptoms in epidemiological research.

Disautonomía gastrointestinal como manifestación de mielitis transversa: Reporte de caso

La mielitis transversa, de origen inflamatorio, es una afectación rara de la médula espinal que afecta a uno o varios niveles. La etiología incluye esclerosis múltiple, causas infecciosas o trastornos del espectro de la neuromielitis óptica. Se presenta de forma aguda, con síntomas motores, sensoriales y/o disautonómicos como los gastrointestinales y urinarios. El diagnóstico se basa en la sintomatología, evolución y se confirma por punción lumbar, resonancia magnética nuclear y analítica sanguínea completa. Se presenta el caso clínico de una paciente con mielitis transversa, que debutó con sintomatología gastrointestinal, síntomas motores y confirmación diagnóstica con resonancia magnética nuclear.

Calidad de vida con y sin cirugía conservadora de esfínteres por cáncer de recto

Introducción: El cáncer colorrectal (CCR) es el tercer cáncer más frecuente y la segunda causa principal de muerte a nivel mundial con una incidencia 10,2%. El tratamiento del CCR ha cambiado durante los últimos 25 años. Se utilizan dos manejos quirúrgicos: la resección abdominoperineal (RAP) y la resección anterior baja (RAB) y la ultra baja (RAUB). La tasa de recidiva y la calidad de vida son similares. Objetivo: Comparar la calidad de vida de los pacientes con cáncer de recto tratados con resección abdominoperineal vs resecciones conservadoras de esfínteres: anterior baja y ultra baja en la UMAE Puebla. Métodos: Se realizó un estudio comparativo, observacional, transversal en pacientes con CCR atendidos durante 2015-2019 en un hospital de 3er nivel en Puebla. Se formaron dos grupos: los manejados con RAP y los manejados con RAB/RAUB. Se aplicó la escala EORT QLQ CR-29 y EuroQol. Se aplicó estadística descriptiva y U de Man-Whitney para comparaciones. Resultados: Se reclutaron 26 pacientes, 18 manejados con RAP y 8 con RAB/RAUB. Se registró una CV media en el grupo RAP de 73,72 (DE 16,92, mínimo 31,46, máximo 95,09) y en el grupo RAB/RAUB de 56,22 (DE 6,29, mínimo 47,51, máximo 68,96), con un valor de p=0,005. Conclusiones: No hay diferencia significativa en la calidad de vida de los pacientes con CCR operados por RAP, RAB y RAUB (abordaje no conservador y conservador).

Introduction: Colorectal cancer (CRC) is the third most common cancer and the second leading cause of death worldwide, with an incidence of 10.2%. The treatment of CRC has evolved over the past 25 years. Two surgical procedures are used: abdominoperineal resection (APR) and low anterior resection (LAR) and ultra-low anterior resection (ULAR). The recurrence rate and quality of life are similar between these approaches. Objective: To compare the quality of life of rectal cancer patients treated with abdominoperineal resection versus conservative sphincter-preserving surgeries: low anterior resection (LAR) and ultra-low anterior resection (ULAR) at UMAE of Puebla. Methods: A comparative, observational, cross-sectional study was conducted on CRC patients treated between 2015 and 2019 at a tertiary-level hospital in Puebla. Two groups were formed: those managed with APR and those managed with LAR/ULAR. The EORTC QLQ-CR29 scale and EuroQol were applied. Descriptive statistics and the Mann-Whitney U test were used for comparisons. Results: A total of 26 patients were recruited, 18 with APR and 8 with LAR/ULAR. The mean quality of life score in the APR group was 73.72 (SD 16.92, minimum 31.46, maximum 95.09), and in the LAR/ULAR group was 56.22 (SD 6.29, minimum 47.51, maximum 68.96), with a p-value of 0.005. Conclusions: There is no significant difference in the quality of life of CRC patients operated with APR, LAR, and ULAR (non-conservative and conservative approaches).
