ABSTRACT

Introducción. El cáncer colorrectal es uno de los tipos de cáncer más comunes y mortales a nivel mundial. Aunque los avances médicos han mejorado el manejo, la cirugía sigue siendo fundamental. La resección anterior baja (RAB) de recto ha ganado relevancia, a pesar de que puede llevar al síndrome de resección anterior baja de recto (LARS, por sus siglas en inglés), afectando la calidad de vida. Métodos. Estudio de corte transversal con intención analítica en un centro de referencia en Medellín, Colombia. Los pacientes con cáncer de recto sometidos a RAB entre enero de 2016 y diciembre de 2022 completaron el cuestionario LARS para evaluar disfunción intestinal. Se evaluaron factores relacionados con la presencia de LARS por medio de un análisis bivariado. Resultados. De 234 pacientes elegibles, 110 (47 %) respondieron la encuesta, predominantemente mujeres (58,2 %). La edad promedio fue 62 años. Dos tercios de los pacientes recibieron neoadyuvancia y el 69 % requirieron ileostomía. La prevalencia de LARS fue 47,3 %. El 80,9 % llevaban más de 12 meses desde la cirugía o el cierre del estoma. Factores estadísticamente significativos asociados a LARS fueron edad mayor de 65 años (p=0,03), estadío patológico avanzado (p=0,02) y requerimiento de estoma (p=0,03). Conclusiones. El LARS afecta a casi la mitad de los pacientes en diferentes etapas posquirúrgicas. El LARS scorees una herramienta práctica para evaluar la función intestinal en el seguimiento del paciente. La prevalencia y los factores de riesgo identificados contribuyen a la comprensión del impacto de la cirugía conservadora del esfínter en la calidad de vida de los pacientes.


Introduction. Colorectal cancer is one of the most common and deadly types of cancer worldwide, with a high incidence of rectal cancer. Although medical advances have improved management, surgery remains crucial. Low anterior resection of the rectum (LAR) has gained significance, despite its potential to lead to low anterior resection syndrome (LARS), affecting quality of life. Methods. A cross-sectional study with analytical intent was conducted at a referral center in Medellín, Colombia. Patients with rectal cancer who underwent LAR between January 2016 and December 2022 completed the LARS questionnaire to assess intestinal dysfunction. Factors related to the presence of LARS were analyzed using bivariate analysis. Results. Of 234 eligible patients, 110 (47%) responded, predominantly women (58.2%). The average age was 62 years. Two-thirds of patients received neoadjuvant therapy and 69% required ileostomy. The prevalence of LARS was 47.3%. 80.9% had been more than 12 months post-surgery or stoma closure. Statistically significant factors associated with LARS included age over 65 years (p=0.03), advanced pathological stage (p=0.02), and stoma requirement (p=0.03). Conclusions. LARS affects almost half of the patients in various post-surgical stages. The LARS score is a practical tool for assessing intestinal function in patient follow-up. The prevalence and risk factors identified contribute to the understanding of the impact of sphincter-conserving surgery on patients' quality of life.

ABSTRACT

Abstract Background and objectives: The rates of (interval) stomach cancer (SC) or postendoscopy (PECRC) or postcolonoscopy (PCCRC) colorectal cancer (CRC) have been little studied in our setting. Data from overseas studies reported PECRC and PCCRC rates of 7-26%. We aim to determine and compare local PECRC and PCCRC rates and characteristics. Patients and methods: With data from three quaternary-care cancer centers, we ambispectively identified patients diagnosed with SC and CRC between 2012 and 2021, in whom a history of endoscopies or colonoscopies in the previous three years was investigated. Cancers diagnosed between 6 and 36 months after an endoscopic study reported as normal were defined as interval cancers. This study compares the clinical, endoscopic, and survival characteristics of both PECRC and PCCRC cohorts. Results: Of 828 patients diagnosed with SC, 66 had PECRC (rate: 7.3%), while in 919 patients with CRC, 68 had PCCRC (rate: 6.9%). There were no significant differences in age or sex, although males predominated (2:1) in the PECRC (0.09). The finding of premalignant lesions was similar in both groups (p = 0.260). The anatomical location was shown to be more proximal (right colon) in the PCCRC than in the PECRC (cardia/fundus) (p = 0.002). Gastric neoplasms were more poorly differentiated (58%) than colon neoplasms (26%) (p = 0.001). There were no differences in early cancers, but tumor status was more advanced in PECRC (p < 0.01). The Kaplan-Meier showed a worse survival for PCCRC than for detected CRC, with no differences in SC and PECRC, suggesting poor survival. Conclusions: The rate of interval cancers is 7.3% and 6.9%, and differences were found between PECRC and PCCRC, proximal locations of the lesions, degree of differentiation, tumor status, and poor survival for the PCCRC. Establishing measures to achieve the World Endoscopy Organization's goal of <5% is necessary.


Resumen Antecedentes y objetivos: Las tasas de cáncer gástrico (CG) o cáncer colorrectal (CCR) posendoscopia (CGPE) o poscolonoscopia (CCRPC) (de intervalo) han sido poco estudiadas en nuestro medio. Los datos de estudios en el exterior informaron tasas de CGPE y CCRPC de 7%-26%. Nuestro objetivo fue determinar y comparar las tasas y características del CGPE y CCRPC locales. Pacientes y métodos: Con datos de tres centros oncológicos de cuarto nivel se identificaron, de forma ambispectiva, pacientes diagnosticados con CG y CCR entre 2012 y 2021, en quienes se investigó el antecedente de endoscopias o colonoscopias en los tres años previos. Los cánceres diagnosticados entre 6 y 36 meses después de un estudio endoscópico reportado como normal se definieron como cánceres de intervalo. En este estudio se comparan las características clínicas, endoscópicas y de sobrevida entre ambas cohortes de cánceres posendoscopia y poscolonoscopia. Resultados: De 828 pacientes diagnosticados con CG, 66 tuvieron CGPE (tasa: 7,3%), mientras que en 919 pacientes con CCR, 68 pacientes presentaron CCRPC (tasa: 6,9%). No hubo diferencias significativas en la edad o el sexo, aunque predominó el masculino (2:1) en el CGPE (0,09). El hallazgo de lesiones premalignas fue similar en ambos grupos (p = 0,260). La ubicación anatómica mostró ser más proximal (colon derecho) en el CCRPC que en el CGPE (cardias/fondo) (p = 0,002). Las neoplasias gástricas fueron más mal diferenciadas (58%) que las de colon (26%) (p = 0,001). No hubo diferencias en los cánceres tempranos, pero el estado tumoral fue más avanzado en el CGPE (p < 0,01). El Kaplan-Meier mostró una peor sobrevida para el CCRPC que para el CCR detectado, sin diferencias en el CG y el CGPE, que mostraron una pobre sobrevida. Conclusiones: La tasa de cánceres de intervalo es de 7,3% y 6,9%, y se encontraron diferencias entre los CGPE y el CCRPC, ubicaciones proximales de las lesiones, grado de diferenciación, estado del tumor y una pobre sobrevida para el CCRPC. Se hace necesario establecer medidas para lograr la meta de la Organización Mundial de Endoscopia de <5%.

ABSTRACT

BACKGROUND: Proctocolectomy with ileal reservoir is the surgical procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis. OBJECTIVES: To evaluate long-term postoperative complications (1994-2019) in patients operated for familial adenomatous polyposis (FAP) and ulcerative colitis (UC) and the degree of satisfaction with the procedure. METHODS: Observational study based on the analysis of a retrospective database with prospective follow-up in 115 consecutive patients: 79 with UC and 36 with FAP. A total of 88 patients were followed up, 60 with UC and 28 with PFA. RESULTS: 48 males (54.4%) with a mean age of 44.8 ± 10.6 years were evaluated. Indications for surgery were intractable disease in 54 patients (47%), dysplasia/cancer in 43 (37%), severe bleeding in 4 (4%) and perforation in 3 (3%). A proctectomy and mucosectomy of the rectal stump was performed in 67 (76.1%), and a double stapling technique in 21. A protective ileostomy was performed in all patients with UC and FAP. No differences were found in early complications between the two groups. Late complications showed a higher rate of reservoritis in UC patients compared to FAP (44.9 vs. 14.3%, p = 0.001), with more refractory reservoritis in the UC group (13.3 vs. 0%, p = 0.04) with no differences in bowel obstruction, strictures, or anastomotic fistulas. Overall satisfaction and adaptation were considered good in 87% of UC patients and only 57% in the FAP group (p < 0.01). CONCLUSIONS: Proctocolectomy with ileal reservoir has comparable morbidity and mortality, except for the higher rate of reservoritis in patients with a history of UC, despite this contingency there is a better quality of life and greater acceptance of surgery in UC patients than in FAP patients.

ABSTRACT

Introducción. El pilar fundamental del tratamiento del cáncer colorrectal es la cirugía, situación que expone a los pacientes a la posible presentación de complicaciones, morbimortalidad, pobre calidad de vida, recurrencia tumoral o la muerte. El objetivo de este estudio fue determinar las variables clínicas y quirúrgicas que inciden en el riesgo de la aparición de complicaciones en los pacientes con cáncer colorrectal llevados a cirugía electiva entre los años 2016 y 2019. Métodos. Estudio observacional, descriptivo, transversal y retrospectivo. Se incluyeron pacientes mayores de 18 años con cáncer colorrectal sometidos a cirugía electiva. Se realizó un análisis multivariado para determinar los factores que se relacionan con las complicaciones postquirúrgicas. Resultados. Se incluyeron 298 pacientes, 68 % mayores de 60 años, 52,3 % mujeres, 74,2 % presentaban comorbilidades y 48,3 % fueron diagnosticados en estadio III. El 48,3 % presentó complicaciones postoperatorias. De ellos, el 68,1 % no tenía tamización nutricional y el 61,8 % no tenía preparación del colon; un 55 % fueron cirugías del recto, 69,1 % de las cirugías fueron por vía laparoscópica y 71,8 % presentaron sangrado inferior a 500 ml. La mayoría de las complicaciones fueron clasificadas como Clavien-Dindo I-III. Discusión. Las características de los pacientes fueron similares a los presentados en otros estudios, aunque hubo mayor incidencia de íleo postoperatorio. El análisis multivariado mostró una mayor probabilidad de presentar una complicación en pacientes con diabetes mellitus, hipertensión arterial, falta de tamización nutricional o preparación de colon, cirugía de recto y el sangrado mayor a 500 ml


Introduction. The fundamental pillar of colorectal cancer treatment is surgery, a situation that exposes patients to the possible presentation of complications, morbidity and mortality, poor quality of life, tumor recurrence or death. The objective of this study was to determine the clinical and surgical variables that affect the risk of the appearance of complications in colorectal cancer patients taken to elective surgery between 2016 and 2019.Methods. Observational, descriptive, cross-sectional and retrospective study. Patients over the age of 18 with colorectal cancer undergoing elective surgery were included. A multivariate analysis was performed to determine the factors related to postsurgical complications. Results. We included 298 patients, 68% over 60 years of age, 52.3% women, 74.2% had comorbidities and 48.3% were diagnosed in stage III. 48.3% presented postoperative complications; of these, 68.1% had no nutritional screening, and 61.8% had no colon preparation; 55% were rectal cancer surgeries, 69.1% underwent laparoscopic surgeries, and 71.8% had bleeding less than 500 ml. Most complications were classified as Clavien Dindo I-III. Discussion. The characteristic of the patients was similar to those presented in other studies, even though we had more incidence of postoperative ileus. The multivariate analysis showed a higher probability of complications in patients with: diabetes, hypertension, lack of nutritional screening, bleeding over 500cc, lack of colon mechanical preparation and rectal cancer surgery.Patient characteristics were similar to those presented in other studies, although there was a higher incidence of postoperative ileus. The multivariate analysis showed a greater probability of presenting a complication in patients with diabetes mellitus, arterial hypertension, lack of nutritional screening, colon preparation, rectal cancer surgery, and bleeding greater than 500 ml
