Influence of Bowel Habit and Hormonal Changes on the Development of Hemorrhoidal Disease During Pregnancy and the Postdelivery Period: A Prospective Cohort Study.

BACKGROUND: Hemorrhoidal disease in women during pregnancy is common in clinical practice. However, prospective data on its real prevalence and women's demographics are scarce. OBJECTIVE: The aim of this study was to determine the prevalence of hemorrhoidal disease during pregnancy and to assess its impact on quality of life. In addition, this study aimed to identify the relationship between patients' characteristics, bowel habits, hormonal changes, and the presence of symptomatic hemorrhoids. DESIGN: This is a prospective longitudinal cohort study. SETTING: This study was conducted in the Obstetrics Department for pregnancy follow-up. PATIENTS: The patients evaluated were a cohort of pregnant women. INTERVENTION: The study was designed to follow a homogeneous cohort of women for 15 months. Visits took place in the first and third trimesters of pregnancy, and 3 and 6 months after delivery. Women's demographics (age, medical history, bowel habit, Bristol stool scale) and serum determination of pregnancy-related hormones (estrogen, progesterone, and relaxin) were determined. MAIN OUTCOME MEASURES: The primary outcome was the development of hemorrhoidal disease. RESULTS: Overall, 109 women (mean age, 31.2 ± 5.4 years) were included in the study. The prevalence of symptoms and physical findings of hemorrhoidal disease was present in 11% in the first trimester, 23% in the third trimester, 36.2% at 1 month after delivery, and 16.9% at 3 months after delivery. A medical history of hemorrhoidal disease was significantly associated with the diagnosis of hemorrhoids in the first trimester (p < 0.0001) and third trimester (p = 0.005). Symptoms of constipation were associated with this clinical disorder in the first trimester (p = 0.011) and the third trimester of pregnancy (p = 0.022). No association was found between hormonal changes and the development of hemorrhoidal disease. LIMITATIONS: A larger sample would provide more information. CONCLUSIONS: The prevalence of women with hemorrhoidal disease increases during pregnancy and after delivery. A history of hemorrhoidal disease and constipation is significantly associated with the diagnosis of symptomatic hemorrhoidal disease. See Video Abstract at http://links.lww.com/DCR/B504.

Anatomic and functional evaluation of the levator ani muscle after an obstetric anal sphincter injury.

PURPOSE: To study the relationship between symptoms of anal incontinence (AI) and the anatomy and functionality of the levator ani muscle in women with a history of obstetric anal sphincter injury (OASI). METHODS: This is a cohort study including patients with OASI from 2013 to 2016. Patients were assessed by a physical examination, endoanal ultrasound using Starck Scale, perineometry and 4D transperineal ultrasound. AI in all patients was measured with the Wexner scale. Correlation between variables has been analyzed in these patients. RESULTS: 72 patients were analyzed: 28 with a IIIA degree tear, 26 with a IIIB, 13 with a IIIC and 5 with a IV. 38 patients showed a residual anal sphincter (AS) defect on endoanal ultrasound with an average Starck score of 6.5 ± 3.7. 21 patients expressed AI, with an average Wexner score of 4.1 ± 2.4. In 27 (37.5%) patients, a levator ani avulsion was observed: 17 unilateral and 10 bilateral. Patients with a levator ani defect had weaker pelvic floor muscle (PFM) function. These differences were statistically significant with perineometry (p = 0.01 and p = 0.03) but not for the Oxford test (p = 0.08). Patients with a residual AS defect as well as an injury to the levator ani muscle expressed greater AI symptomatology than patients with residual sphincter injury who maintain the integrity of the levator ani: Wexner 4.9 0.9 vs 3.3 1 (p = 0.02). CONCLUSIONS: The PFM has correlation with AI symptom development in patients with a history of OASI. Therefore, we suggest a key role of anatomical and functional assessments of the levator ani muscle in these patients.

Prevalence of Fecal Incontinence in Women During Pregnancy: A Large Cross-Sectional Study.

BACKGROUND: Although some studies have analyzed the prevalence of urinary incontinence during pregnancy, there are scarce data on the frequency and characteristics of fecal incontinence during this period. OBJECTIVE: The aim of this study was to determine the incidence and characteristics of women with fecal incontinence symptoms during early and late pregnancy, to evaluate its impact on quality of life, and to identify whether there is a specific clinical pattern that could identify patients at risk. DESIGN: This was a cross-sectional observational study. SETTINGS: The study was conducted at the maternity unit of a university tertiary care center. PATIENTS: Pregnant women undergoing obstetric follow-up were included in the study. MAIN OUTCOME MEASURES: A prospective study was conducted. All of the patients attending our maternity unit for obstetric ultrasound examination during the first and third trimesters were eligible for inclusion. Selected patients completed a self-reported questionnaire that included items on fecal incontinence, Wexner score, and stool consistency. Quality of life was assessed using the Medical Outcomes Study Short Form 36. RESULTS: The study included 228 consecutive pregnant women. Ninety-three patients (40.8%) had some episode of fecal incontinence in the 4 weeks before the survey, 15 patients with solid stool, 6 patients with liquid stools, and 72 with flatus. In these patients, the mean Wexner score was 3.82 (range, 2.0-13.0). In patients with incontinence, quality of life was significantly affected in most subscales of Medical Outcomes Study Short Form 36. There were no significant differences in the following variables between patients with and without symptoms of fecal incontinence, including age (p = 0.090), BMI (p = 0.094), history of previous deliveries (p = 0.492), trimester of pregnancy (p = 0.361), and Bristol Stool Form Scale (p = 0.388). LIMITATIONS: The cross-sectional design hampered identification of specific time at which the impact of pregnancy occurred. CONCLUSIONS: The prevalence of fecal incontinence is high during pregnancy with a notable impact on quality of life. There was no specific clinical pattern during pregnancy that could define patients at risk for fecal incontinence during this period of life.

Risk factors for umbilical trocar site incisional hernia in laparoscopic cholecystectomy: a prospective 3-year follow-up study.

BACKGROUND: Trocar site incisional hernia (TSIH) is a common complication after laparoscopic cholecystectomy. The aim of this study was to evaluate the prevalence of TSIH and analyze the influence of several risk factors for this complication in a prospective series. METHODS: From 2007 to 2008, a prospective observational study with 3 years of follow-up was performed including all consecutive patients with cholelithiasis who underwent elective laparoscopic cholecystectomy. A multivariate analysis was performed to identify risk factors for TSIH. RESULTS: Overall, 241 patients were included. During a median follow-up period of 46.8 months, 57 patients (25.9%) were diagnosed with umbilical TSIH by physical exam or ultrasound. The multivariate analysis revealed that incision enlargement (odds ratio [OR], 14.17; 95% confidence interval [CI], 3.61 to 55.51; P < .001), wound infection (OR, 5.62; 95% CI, 2.35 to 13.42; P < .001), diabetes mellitus (OR, 2.79; 95% CI, 1.05 to 7.37; P = .0038), and obesity (OR, 2.71; 95% CI, 1.28 to 5.75; P = .009) contributed to the risk for developing a TSIH. CONCLUSIONS: Umbilical TSIH is highly prevalent. This study identified several factors that could be useful to introduce preventive measures in high-risk patients.

Variación en las reclamaciones dirigidas a un Servicio de Cirugía General y del Aparato Digestivo tras un cambio estructural y funcional hospitalario / Changes in the complaints made to a General and Gastrointestinal Surgery Department after a change in hospital structure and function

Objetivo Las reclamaciones de un servicio médico son una medida de la calidad asistencial percibida por los pacientes. El objetivo del estudio fue analizar la variación producida en el porcentaje de reclamaciones dirigidas al Servicio de Cirugía General y del Aparato Digestivo (CGD) en relación a los cambios producidos por el traslado a un nuevo hospital. Material y métodos Estudio longitudinal del porcentaje de reclamaciones dirigidas al Servicio de CGD en dos periodos de 6 meses de un mismo año (periodos A y B). Entre uno y otro periodo se realizó el traslado a un nuevo hospital. Se compara el porcentaje de reclamaciones asociadas a la actividad hospitalaria y en consultas externas. Resultados El porcentaje de reclamaciones dirigidas al Servicio de CGD fue del 3,02% dirigidas a las altas de hospitalización y 0,44% dirigidas a la atención en consultas externas. Cuando se compararon ambos periodos, se observó una disminución estadísticamente significativa de las reclamaciones en hospitalización (A: 3,74% vs B: 2,20%, p=0,006) y en consultas externas (A: 0,53% vs. B: 0,34%, p=0,005). Se pudo constatar también que la disminución paralela de las reclamaciones de hospitalización y de consultas externas siguió una correlación lineal significativa (R:0,988 p<0,001).Conclusiones El cambio estructural y funcional por el traslado a un nuevo hospital comportó que el porcentaje de reclamaciones dirigidas al Servicio de CGD disminuyera de manera significativa en el periodo estudiado. Son necesarios estudios prospectivos y multicéntricos que permitan evaluar si estos resultados son superponibles a otros medios (AU)

Objective The complaints to a medical service are a measure of the quality of health care perceived by the patients. The aim of this study was to analyse the differences found in the percentage of complaints made to the General and Gastrointestinal Surgery Department (GGSD) with the changes made due to moving to a new hospital. Material and methods A longitudinal study of the percentage of complaints made to the GGSD in two 6 month periods in the same year (periods A and B). The Department was moved to a new hospital between the two periods. The percentage complaints associated with the hospital and outpatient activity is compared. Results The percentage complaints made to the GGSD was 3.02% directed at the hospital service and 0.44% to outpatient care. When both periods were compared, a statistically significant difference was observed in the hospital complaints (A: 3.74% vs B: 2.20%, P=.006) and in the outpatient complaints (A: 0.53% vs. B: 0.34%, P=.005). It could also be shown that there was a continuous significant correlation in the parallel decrease in the hospital and outpatient complaints (R:0.988P<.001).Conclusions The structural and functional change due to moving to a new hospital showed that the percentage of complaints made to the GGSD changed significantly in the period studied. Prospective multicentre studies are required to evaluate whether these results can be extrapolated to other services (AU)

Prospective analysis of clinician accuracy in the diagnosis of benign anorrectal pathology: the value of clinical information.

AIM: the prevalence of anorectal disorders in general population is high. The aim of this study was to analyze the influence of clinical symptoms on diagnostic accuracy for benign anorectal pathology among different specialists and evaluate the relationship between diagnostic accuracy and years of professional experience. METHODS: seven typical cases were selected. In a first interview, participants were shown images and asked to make a diagnosis. Afterwards, images with additional information (clinical symptoms) were used. Two groups (group 1 = general surgeons and group 2 = medical specialists who attended emergency department) completed both phases of the study to analyze the influence of clinical symptoms on the final diagnosis. RESULTS: forty four specialists were interviewed. The percentage of participants making a correct diagnosis in groups 1 and 2, respectively, was as follows: case 1 (perianal abscess): 100 vs. 80.6%, (p = 0.157); case 2 (fissure): 92.3 vs. 51.6% (p = 0.015); case 3 (thrombosed hemorrhoid): 92.3 vs. 74.2% (p = 0.321); case 4 (anal condyloma): 100 vs. 87.1% (p = 0.302); case 5 (rectal prolapse): 100 vs. 83.9% (p = 0.301); case 6 (prolapsed hemorrhoid): 92.3 vs. 29% (p = 0.001), and case 7 (fistula): 100 vs. 67.7% (p = 0.021). There were significant differences in the number of correctly diagnosed cases between groups (p < 0.001). Information about clinical symptoms significantly increased overall and specific accuracy. There was no correlation between experience and accuracy. CONCLUSIONS: clinical symptoms are important for diagnostic accuracy in anorectal pathology. Training in anorectal pathology in medical specialists is warranted.

Análisis prospectivo de la precisión diagnóstica en la patología anorrectal benigna: importancia de la información clínica / Prospective analysis of clinician accuracy in the diagnosis of benign anorectal pathology: the value of clinical information

Objetivo: la prevalencia de los trastornos anorrectales benignos en la población general es alta. El objetivo de este estudio es analizar la influencia de los síntomas clínicos en la precisión diagnóstica de la patología benigna anorrectal entre los diferentes especialistas y evaluar la relación entre el diagnóstico de la enfermedad y los años de experiencia profesional entre los profesionales participantes. Pacientes y métodos: se seleccionaron 7 casos típicos. En una primera entrevista, se mostró a los participantes las imágenes clínicas de cada caso y se les pidió que formularan un diagnóstico. Posteriormente, se volvió a mostrar las mismas imágenes con información clínica adicional. Dos grupos (grupo 1 = especialistas en cirugía general y digestiva y grupo 2 = especialistas de especialidades médicas con asistencia en el área de urgencias) completaron las dos fases del estudio para analizar la influencia de los síntomas clínicos en el diagnóstico final. También se analizó la relación entre la precisión diagnóstica y los años de experiencia de cada profesional. Resultados: se entrevistaron a 44 especialistas. El porcentaje de participantes que realizó un diagnóstico correcto en el grupo 1 y 2, fue respectivamente: caso 1 (absceso perianal): 100 vs. 80.6%, (p = 0,157); caso 2 (fisura anal): 92,3 vs. 51.6% (p = 0,015); caso 3 (hemorroide trombosada): 92,3 vs. 74,2% (p = 0,321); caso 4 (condiloma anal): 100 vs. 87,1% (p = 0,302); caso 5 (prolapso rectal): 100 vs. 83.9% (p = 0,301); caso 6 (prolapso hemorroidal): 92,3 vs. 29% (p = 0,001), y caso 7 (fístula perianal): 100 vs. 67,7% (p = 0,021). Se observaron diferencias en el número de los diagnósticos correctos entre grupos (p < 0,001). Globalmente, la información sobre síntomas clínicos incrementó significativamente la precisión específicamente, no observándose correlación entre experiencia profesional y precisión. Conclusiones: los síntomas clínicos son importantes para la precisión diagnóstica de la patología anorrectal benigna. La formación específica de especialistas médicos en esta patología anorrectal está claramente justificada(AU)

Results of implementation of a fast track pathway for diagnosis of colorectal cancer.

INTRODUCTION: fast track pathways for diagnosis of cancer intend to decrease delays in diagnosis and treatment of cancer. It is recommended to initiate treatment in a period no longer than 30 days since admission in these circuits. AIMS: to know the characteristics and fluency of our Fast Track Diagnostic Pathway (FTDP) for Colorectal Cancer (CRC), with special attention to those patients selected for surgical treatment as a first choice. MATERIAL AND METHOD: all patients who entered the FTDP for CRC during a period of 2 years (2008-2009) were analyzed as well as the rest of patients also diagnosed with CRC but never seen in the FTDP. RESULTS: of the 316 patients referred to the FTDP only 78 (24.7%) were diagnosed as having some kind of cancer derived from the digestive system. At the end 61 patients (19.3%) were diagnosed with CCR. The time interval from entry into the FTDP to the first hospital visit was 3 days (range 1-8), and the interval until colonoscopy was performed was 11.5 days (range 1-41). Fourteen (41.1%) of those patients chosen for surgery were operated on in a period lesser than 30 days while 28 patients (82.3%) underwent surgery before day 45 since admission into the circuit. CONCLUSIONS: though the functioning of the FTDP is acceptable, any increase in number of patients can generate delays. For this reason it is advisable to have a team to assure a good functioning of the FTDP. A proper follow-up of the whole process will possibly avoid unnecessary delays and it will improve coordination of the different phases of the fast track pathway and treatment. As the diagnostic outcome is poor it is mandatory to implement alternatives programs like screening of asymptomatic population, allowing an early detection of this condition.

Resultados de la implementación del circuito de diagnostico rápido de cáncer colorrectal / Results of implementation of a fast track pathway for diagnosis of colorectal cancer

Introducción: los circuitos de diagnóstico rápido de cáncer (CDRC) pretenden disminuir las demoras en el diagnóstico y tratamiento del cáncer colorrectal (CCR). Se recomienda el inicio del primer tratamiento en un plazo de 30 días desde la entrada en el circuito de diagnóstico rápido. Objetivos: conocer las características y fluidez de nuestro circuito de diagnóstico rápido del cáncer colorrectal (CDRC), centrando el interés en los pacientes cuyo primer tratamiento va a ser el quirúrgico. Material y método: se analizan los pacientes que ingresan el circuito de diagnóstico rápido durante un periodo de 2 años (2008- 2009) y también los pacientes diagnosticados durante el tiempo del estudio por otras vías. Resultados: acceden al circuito de diagnóstico rápido 316 pacientes, 78 pacientes (24,7%) presentan cáncer digestivo, siendo finalmente diagnosticados de CCR 61 pacientes (19,3%). El intervalo de tiempo desde la entrada al CDRC hasta la primera visita en el hospital fue de 3 días (rango 1-8), y el intervalo hasta la realización de la colonoscopia fue de 11,5 días (rango 1-41). Los pacientes candidatos a cirugía que fueron intervenidos en un intervalo inferior a 30 días fueron 14 (41,1%), 28 pacientes (82,3%) fueron intervenidos antes de los 45 días. Conclusiones: la rapidez del circuito es aceptable pero cualquier aumento de la demanda puede generar retrasos, con lo que un responsable de seguimiento del proceso posiblemente evitará demoras y mejorará la coordinación en las diferentes fases del circuito y tratamiento. El rendimiento diagnóstico es bajo por lo que hay que pensar en la aplicación de alternativas ya existentes, como el cribado poblacional, que permitan el diagnóstico precoz en pacientes que aún no presentan sintomatología(AU)
