ABSTRACT
【Objective】 To study the diagnostic value of balloon expulsion test, anorectal manometry, and colonic transit test for detecting constipation with defecation disorders. 【Methods】 Outpatients with functional constipation were retrospectively analyzed and classified into dyssynergic defecation constipation and non-dyssynergic defecation constipation according to the Rome Ⅳ diagnostic criteria. We studied the differences in symptomatological characteristics and results of the three testing methods between the two groups of patients. 【Results】 Among the 48 patients with functional constipation included, there were 13 males (27.1%) and 35 females (72.9%) with an age of (44.8±12.3) years, including 32 patients (66.7%) with defecation disorder and 16 patients (33.3%) with non-defecation disorder. The percentage of anal distension was significantly higher in patients with dyssynergic defecation constipation than in those with non-dyssynergic defecation constipation (34.4% vs. 0.0%, P=0.021). All the three tests had diagnostic value for dyssynergic defecation constipation, but with low diagnostic agreement between the results of each test. The diagnostic sensitivity of anorectal manometry was 100%, but the specificity (56.3%) was low, and both the positive predictive value (82.1%) and the negative predictive value (100%) were higher; the diagnostic sensitivity (75.0%) and specificity (81.3%) of the balloon expulsion test were both higher. The Youden index of colonic transit test was the smallest. The anal resting pressure and maximum systolic pressure of dyssynergic defecation constipation were lower than those of non-dyssynergic defecation constipation (75.2 mmHg vs. 97.1 mmHg, 168.7 mmHg vs. 251.6 mmHg). The two types of constipation did not significantly differ in anorectal pressure gradients during simulated defecation or rectal sensory function. 【Conclusion】 The balloon expulsion test can be used as a primary screening test for constipation with defecation disorders, and anorectal manometry has the highest comprehensive diagnostic value, but there is a certain false positive rate, and the colonic transit test has the lowest diagnostic efficacy. Thus a comprehensive analysis of the patient’s symptoms and the results of different tests is needed in clinical practice.
ABSTRACT
Objective:To compare the results of high-resolution colonic manometry (HRCM) in patients with four subtypes of constipation: slow transit constipation(STC), outlet obstruction constipation (OOC), mixed STC and OOC, and normal transit constipation(NTC), and to explore the intestinal motility characteristics of patients with different subtypes of constipation.Methods:From 20th January 2017 to 20th September 2020, the HRCM results of 225 patients with functional constipation who visited the Department of Anorectal Surgery of Tianjin Union Medical Center were retrospectively analyzed. According to the results of colonic transit test, 225 patients were divided into STC group (108 cases), OOC group (36 cases), mixed group (28 cases) and NTC group (53 cases). General information such as Wexner constipation scores, clinical symptoms (decreased desire to defecate, sensation of anorectal blockage, hand-assisted defecation, spontaneous bowel movements frequency<3 times per week), the incidence, frequency within one day (hereinafter referred to as frequency), average velocity, average wave amplitude, average duration of contraction, average length of contraction, and the dynamic index (DI) of average pressure of high-amplitude propagating contraction (HAPC), as well as the frequency, average wave amplitude, average duration of contraction, and the DI of average pressure of low-amplitude propagating contraction (LAPC) were compared among the four groups. One-way ANOVA and multiple comparison, Kruskal-Wallis test and chi-square test were used for statistical analysis.Results:The Wexner constipation scores of the STC, OOC, mixed and NTC group were 13.17±4.04, 13.97±4.55, 11.36±4.03 and 11.58±4.06, respectively, and the difference was statistically significant ( F=3.879, P<0.05). The Wexner consipation scores of the STC and OOC group were both higher than the mixed and NTC group, and the difference were statistically significant (One-way ANOVA and multiple comparison, all P<0.05). The proportion of decreased desire to defecate, sensation of anorectal blockage, hand-assisted defecation, spontaneous bowel movements frequency<3 times per week of STC, OOC, mixed and NTC group were 47.2% (51/108), 36.1% (13/36), 14.3% (4/28), 20.8% (11/53); 42.6% (46/108), 75.0% (27/36), 46.4% (13/28), 64.2% (34/ 53); 31.5% (34/108), 38.9% (14/36), 3.6% (1/28), 18.9% (10/53); 90.7% (98/108), 77.8% (28/36), 82.1% (23/28) and 62.3% (33/53), and the differences were statistically significant ( χ2=17.093, 12.463, 13.437 and 18.927; all P<0.01). The proportion of decreased desire to defecate of STC group was higher than that of mixed and NTC group, and spontaneous bowel movements frequency<3 times per week was higher than that of OOC and NTC group, and the differences were statistically significant ( χ2=10.014, 10.518, 4.418 and 19.016; all P<0.05). The proportion of sensation of anorectal blockage of OOC group was higher than that of STC and mixed group, and the proportion of hand-assisted defecation was higher than that of the mixed and NTC group, and the differences were statistically significant ( χ2= 9.511, 5.486, 10.948 and 4.363, all P<0.05). The incidence of HAPC in STC, OOC, mixed and NTC groups was 39.8% (43/108), 36.1% (13/36), 57.1% (16/28), and 60.4% (32/53), respectively, and the difference was statistically significant ( χ2=8.880, P=0.031). The incidence of HAPC in STC group and OOC group were lower than that of NTC group, and the differences were statistically significant ( χ2=6.041 and 5.050, P=0.014 and 0.025). There were no statistically significant difference in the frequency, average velocity, average amplitude, average duration of contraction, average length of contraction and DI of pressure of HAPC in four groups, and there were no statistically significant difference in the frequency, average amplitude, average duration of contraction, and DI of pressure of LAPC in the four groups (all P>0.05). Conclusions:Doctors can more clearly and objectively observe the intestinal motility characteristics of patients with different subtypes of constipation through HRCM. HRCM provides a strong basis for the diagnosis and further treatment of functional constipation, and has a high clinical application value.
ABSTRACT
Objective To analyze the colonic transit time in patients with different severities of constipation.Methods From June, 2015 to September, 2017, 73 male patients with supraconal spinal cord injury were grouped as mild constipation group (n = 25) and severe constipation group (n = 48). They were measured the transit time of entire colorectum, ascending colon (including the right colic flexure), transverse colon, descending colon (including the left colic flexure) and rectosigmoid with Abrahamsson method.Results The transit time of entire colorectum, transverse colon, descending colon increased in the severe constipation group compared with that of the mild constipation group (P ＜ 0.05). For each group, the transit time of rectosigmoid was the longest among colon segments (P ＜ 0.05).Conclusion The colonic transit time of SCI male patients with various constipation is different in colon segments. Accurate interventions are needed to target colon segments.
ABSTRACT
OBJECTIVE:To observe therapeutic efficacy and safety of prucalopride in the treatment of chronic constipation (CC). METHODS:Totally of 100 CC patients were selected from anorectal department of our hospital during Jun. 2016-Jan. 2017, and then divided into control group and observation group according to random number table,with 50 cases in each group. Control group was given Mosapride citrate tablets 5 mg +Lactulose oral solution 10 mL orally,3 times a day. Observation group was given Prucalopride succinate tablets 2 mg orally,once a day. Both groups were treated for consecutive 4 weeks. Clinical efficacies of 2 groups were observed,and the levels of serum inflammatory factors(IL-6,TNF-α,IFN-γ)and colonic transit time(total colonic transit time,left colonic transit time,right colonic transit time,rectosigmoid colonic transit time)were observed before and after treatment. The occurrence of defecation disorders and ADR were recorded. RESULTS:None of patient in 2 groups was cured. Total response rate of observation group was 94.00%,which was significantly higher than 78.00% of control group,with statistical significance (P＜0.05). Before treatment,there was no statistical significance in the levels of serum inflammatory factors or colonic transit time (P＞0.05). After treatment,the levels of IL-6 and IFN-γ in control group,the levels of IL-6,TNF-α and IFN-γ in observation group were decreased significantly,and the levels of IL-6,TNF-α and IFN-γ in observation group were significantly lower than those of control group;the colonic transit time in 2 groups was shortened significantly,and observation group was significantly shorter than control group,with statistical significance (P＜0.05). After treatment,the incidence of defecation,incomplete emptying,sense of obstruction and sense of rectal tenesmus in observation group were significantly lower than control group,with statistical significance(P＜0.05). There was no statistical significance in the incidence of sense of rectal tenesmus after treatment or ADR between 2 groups (P＞0.05). CONCLUSIONS:Compared with traditional plan of mosapride combined with lactulose,prucalopride can more effectively reduce the levels of serum inflammatory factors,shorten colonic transit time,reduce the occurrence of defecation disorders as defecation and incomplete emptying,with equivalent safety.
ABSTRACT
OBJECTIVE@#To evaluate the effects of retrograde colonic electrical stimulation (RCES) with trains of short pulses and RCES with long pulses on colonic transit in irritable bowel syndrome (IBS) rats and to investigate whether stress-induced visceral hypersensitivity could be alleviated by RCES so as to find a valuable new approach for IBS treatment.@*METHODS@#A total of 48 male rats were randomly divided into model group and control group. Visceral hypersensitivity model was induced by a 6-day HIS protocol composed of two stressors, restraint stress for 40 min and forced swimming stress for 20 min. The extent of visceral hypersensitivity was quantified by electromyography and abdominal withdrawal reflex scores (AWRs) of colorectal distension (use a balloon) at different pressures. After the modeling, all rats were equipped with electrodes in descending colon for retrograde electrical stimulation and a PE tube for perfusing phenol red saline solution in the ileocecus. After recovering from surgery, RCES with long pulses, RCES with trains of short pulses, and sham RCES were performed in colonic serosa of rats for 40 min in six groups of 8 each, including three groups of visceral hypersensitivity rats and three groups of health rats. Colonic transit was assessed by calculating the output of phenol red from the anus every 10 min for 90 min. Finally, the extent of visceral hypersensitivity will be quantified again in model group.@*RESULTS@#After the 6-day HIS protocol, the HIS rats displayed an increased sensitivity to colorectal distention, compared to control group at different distention pressures (P < 0.01). CRES with trains of short pulses and long pulses significantly attenuated the hypersensitive responses to colorectal distention in the HIS rats compared with sham RCES group (P < 0.01). The effects of RCES on rats colon transmission: In the IBS rats, the colonic emptying were (77.4 ± 3.4)%, (74.8 ± 2.4)% and (64.2 ± 1.6)% in the sham RCES group, long pulses group and trains of short pulses group at 90 min; In healthy rats, The colonic emptying was (65.2 ± 3.5)%, (63.5 ± 4.0)% and (54.0 ± 2.5)% in the sham RCES group, long pulses group and trains of short pulses group at 90 min.@*CONCLUSION@#RCES with long pulses and RCES with trains of short pulses can significantly alleviate stress-induced visceral hypersensitivity. RCES with trains of short pulses has an inhibitory effect of colonic transit, both in visceral hypersensitivity rats and healthy rats.

ABSTRACT
BACKGROUND/AIMS: The correlation between the Bristol stool form scale (BSFS) and colonic transit time (CTT) has been reported in Western populations. Our study aims to study the relationship between BSFS, stool frequency, and CTT in Eastern patients with chronic constipation. METHODS: A total of 144 chronic functional constipation patients underwent colonic transit study by using radio-opaque markers, anorectal manometry, and balloon expulsion test. Stool diary including stool forms and frequency was recorded. Delayed CTT was defined as the retention of more than 20.0% of radio-opaque markers in the colon on day 5. RESULTS: Twenty-five patients (17.4%) had delayed colonic transit. Mean 5-day BSFS (OR, 0.51; 95% CI, 0.34–0.79; P = 0.021) and stool frequency (OR, 0.60; 95% CI, 0.44–0.83; P = 0.002) were independently associated with delayed CTT by logistic regression analysis. Mean 5-day BSFS (area under the curve [AUC], 0.73; 95% CI, 0.62–0.84; P < 0.001) and stool frequency (AUC, 0.75; 95% CI, 0.63–0.87; P < 0.001) fairly predicted delayed CTT. The optimal mean 5-day BSFS of ≤ 3 provided 68.0% sensitivity, 69.7% specificity, and 69.4% accuracy, and the optimal stool frequency ≤ 2 bowel movements in 5 days provided 64.0% sensitivity, 83.1% specificity, and 84.0% accuracy for predicting delayed CTT. CONCLUSIONS: Both stool form and frequency were significantly associated with delayed CTT. Stool frequency ≤ 2 and BSFS 1–3 rather than BSFS 1–2 that was used in the Westerners could be used as surrogate for delayed CTT in Eastern patients with constipation.

Background:Chronic constipation is a major cause of impaired quality of life in modern society. Reasonable and effective management of chronic constipation could be achieved based on the principle of evidence-based medicine and the modern concept of constipation,and this is a challenge facing the clinicians. Aims:To investigate the role of barium-based colonic transit detection in diagnosis and treatment of chronic constipation. Methods:Fifty patients with chronic constipation from Apr. 2013 to Oct. 2014 at the First Hospital of Shanxi Medical University were recruited and randomly allocated into two groups,control group and individualized treatment group. Patients in individualized treatment group received 20 barium markers orally and abdominal plain radiography was performed 48 and 72 hours later,respectively for calculating the colonic transit index. According to the type of colonic transition and the characteristics of colonic motility estimated by colonic transit index and clinical manifestations,an individualized therapeutic regimen was formulated and the efficacy was evaluated. Patients in control group were treated empirically according to the clinical manifestations. Results:Mosapride and lactulose or polyethylene glycol were administered orally in control group;when abdominal pain or abdominal distension was predominant,pinaverium bromide or trimebutine was used respectively instead of mosapride. Barium-based colonic transit detection revealed that 9 patients in individualized treatment group were slow transit constipation,6 were outlet obstructive constipation and 8 were the mixed type. After 2 weeks of empirical or individualized treatment,the defecation rates of the two groups were 24. 0%(6 / 25)and 52. 2%(12 / 23)within 24 hours and 64. 0%(16 / 25)and 87. 0%(20 / 23)within 48 hours,respectively(P all < 0. 05). Conclusions:Barium-based colonic transit detection is a simple,economical and practical modality for guiding the individualized treatment in patients with chronic constipation.
ABSTRACT
INTRODUCCIÓN: el estreñimiento es un síntoma o afección que puede comprometer la calidad de vida de los pacientes. Su prevalencia global varía entre 2 % y 28 %. OBJETIVO: evaluar la concordancia entre los resultados de los exámenes imagenológicos y la manometría anorrectal, en pacientes con sospecha de estreñimiento funcional. MÉTODOS: la muestra estuvo conformada por 37 pacientes, a los que se les realizó exámenes radiológicos de cecocolografía secuencial (o colon por ingestión), tiempo de tránsito colónico con marcadores radiopacos, defecografía y examen manométrico. Se calculó el índice de Kappa para determinar la concordancia. RESULTADOS: 62,2 % de los enfermos fueron del sexo femenino, la edad predominante estuvo entre 41 y 60 años (43,2 %), predominó el ciego móvil (54,2 %) como causa de estreñimiento. Se hicieron 14 estudios de tiempo de tránsito colónico con marcadores radiopacos, de ellos 28,6 % presentó un tiempo de tránsito lento. Se realizó defecografía a 4 pacientes y 3 presentaron disfunción del suelo pelviano. Se constató que 94,6 % de las pruebas imagenológicas y 78,4 % de las manometrías resultaron positivas (Kappa p= 0,006). CONCLUSIÓN: las técnicas imagenológicas que se investigaron son apropiadas para diagnosticar el estreñimiento funcional y la concordancia de dichas técnicas con la manometría anorrectal es adecuada.

Functional constipation is a common and frequently occurring disease in childhood. In addition to meeting the clinical di-agnostic criteria for constipation and performing the general routine examinations, there are the need to have further examinations such as colonic transit time measurement, anorectal manometry and colonoscopy in order to rule out other causes. Therefore, the purpose of this paper is to introduce several latest research progress in examinations related to constipation in children and to provide some gui-dance and references for clinicians.

BACKGROUND/AIMS: In isolated guinea-pig colon, we investigated regional differences in peristalsis evoked by intrinsic electrical nerve stimulation. METHODS: Four colonic segments from mid and distal colon of Hartley guinea pigs, were mounted horizontally in an organ bath. Measurement of pellet propulsion time, intraluminal pressure, electrical field stimulation (EFS; 0.5 ms, 60 V, 10 Hz), and response of pharmacological antagonists, were performed to isolated segments of colon to determine the mechanisms underlying peristaltic reflexes evoked by focal electrical nerve stimuli. RESULTS: In fecal pellet propulsion study, the velocity of pellet propulsion was significantly faster in the distal colon and decreased gradually to the proximal part of the mid colon. Intraluminal pressure recording studies showed that luminal infusion initiated normal peristaltic contractions (PCs) in 82% trials of the distal colon, compared to that of mid colon. In response to EFS, the incidence of PCs was significantly increased in the distal colon in contrast, the incidence of non-peristaltic contractions (NPCs) was significantly higher in the middle-mid colon, distal-mid colon and distal colon, compared to that of proximal-mid colon. Addition of L-NAME into the bath increased the frequency of NPCs. EFS failed to cause any PCs or NPCs contractions in the presence of hexamethonium, atropine or tetrodotoxin. CONCLUSIONS: This study has revealed that electrical nerve stimulation of distal colon is the most likely region to elicit a peristaltic wave, compared with the mid or proximal colon. Our findings suggest that EFS-evoked PCs can be modulated by endogenous nitric oxide.

ABSTRACT
Constipation is one of the most common functional digestive complaints worldwide. We investigated the laxative effects of figs (Ficus carica L) in a beagle model of constipation induced by high protein diet and movement restriction. The experiments were consecutively conducted over 9 weeks divided into 3 periods of 3 weeks each. All 15 beagles were subjected to a non-treatment (control) period, a constipation induction period, and a fig paste treatment period. We administered fig paste (12 g/kg daily, by gavage) for 3 weeks following a 3-week period of constipation induction in dogs. Segmental colonic transit time (CTT) was measured by counting radiopaque markers (Kolomark) using a radiograph performed every 6 h after feeding Kolomark capsules, until capsules were no longer observed. Fig paste significantly increased fecal quantity in constipated dogs, and segmental CTT was also reduced following fig paste administration. There were no significant differences in feed intake, water intake, body weight, or blood test results, between the constipation and fig paste administration periods. Our results demonstrate that fig is an effective treatment for constipation in beagles. Specifically, stool weight increased and segmental CTT decreased. Fig pastes may be useful as a complementary medicine in humans suffering from chronic constipation.

El tránsito colónico es la medición objetiva del tiempo en el que trascurre el contenido intestinal a través del colon y representa un adelanto muy importante en la evaluación de pacientes con trastornos en el hábito intestinal. Valores normales de tránsito colónico (TC). Determinar valores normales de TC en voluntarios sanos en la ciudad de Caracas. En el Hospital Universitario de Caracas (HUC). Estudio descriptivo, transversal; se empleó anillos metálicos de 8Fr (2.7mm), como marcadores radioopacos, introducidos en capsulas de gelatina tamaño 00 largo (24 anillos/cápsula), se tomaron al azar 30 voluntarios sanos, personal médico y de enfermería del HUC, con edades entre 18 y 50 años, agrupados por género: 15 masculino y 15 femenino. Se realizó radiografías de abdomen simple en posición decúbito dorsal a las 72, 96 y 120 horas posteriores a la ingesta de la cápsula, cuantificando la cantidad de marcadores eliminados. Para el análisis de los resultados se aplicó la prueba no paramétrica U de Mann-Whitney; con un nivel de significación del 95%. No se realizó modificaciones en la dieta durante el estudio. 21 voluntarios (70%) evacuaron más del 80% de los marcadores radiopacos a las 96 horas. 20% (6 voluntarios) registraron la eliminación total de los marcadores antes de las 96 horas. 70% presentó la eliminación de más del 80% de los marcadores de TC a las 96 horas. No se evidenció diferencias estadísticas significativas entre los grupos etarios ni género. Los valores obtenidos son inferiores a los aceptados como normales, reportados en la literatura mundial (eliminación del 80% de los marcadores antes de las 120 horas), y superiores en comparación con un estudio mexicano semejante (eliminación del 80% de los marcadores a las 48 horas)...
The colonic transit is the objective measurement of the time lag in the intestinal contents through the colon and represents an important advancement in the evaluation of patients with intestinal disorders of habit. Normal colonic transit (CT). To determine normal values of CT in healthy volunteers in the city of Caracas. Hospital Universitario de Caracas (HUC). A descriptive cross-functional study; 8Fr (2.7mm) metal rings were used as radiopaque markers, placed into gelatin capsules of 00 long (24 rings / capsule), 30 healthy volunteers, medical and nursing staff of HCU, aged between 18 and 50 years, matched by gender were randomly taken: 15 male and 15 female. A simple abdominal radiography was performed on dorsal decubitus position at 72, 96 and 120 hours after ingesting the capsule, quantifying the amount of markers removed. For the analysis of the results we used the nonparametric Mann-Whitney U test, with a significance level of 95%. No changes were made in the diet during the study. 21 volunteers (70%) evacuated more than 80% of the radiopaque markers at 96 hours. 20% (6 volunteers) reported the total elimination of the markers prior to 96 hours. 70% eliminated over 80% of the markers of the CT at 96 hours. No statistically significant differences were found between age groups or gender. The values obtained are below the ones accepted as normal, reported in the literature (80% elimination of the markers before the 120 hours) and higher compared to a similar Mexican study (80% elimination of the markers at 48 hours)...

BACKGROUND/AIMS: Constipation is a well-recognized gastrointestinal symptom in patients with untreated hypothyroidism. Although thyroid function tests are recommended to exclude hypothyroidism in patients with constipation, there have been no reports to determine the causal relationship between thyroid function and constipation. The aim of this study was to determine the prevalence of hypothyroidism in constipated patients and the clinical features of constipation associated with hypothyroidism. METHODS: A total of 1,481 constipated patients were included. These patients were divided into overt hypothyroidism, subclinical hypothyroidism, and normal thyroid function groups based on thyroid function tests. We reviewed the clinical presentation, anorectal function, colonic transit time, defecographic findings, and response to biofeedback therapy. RESULTS: The prevalence of overt and subclinical hypothyroidism was 0.41% (men, 0.36%; women, 0.53%) and 1.76% (men, 1.28%; women 2.03%), respectively. There were no differences in total or segmental colonic transit times and subtypes of constipation among the normal thyroid function (n=54), overt hypothyroidism (n=4), and subclinical hypothyroidism groups (n=21). On anorectal manometry, the prevalence of dyssynergic defecation did not differ between the three groups. Rectal hyposensitivity was more frequent in the overt hypothyroidism group (overt hypothyroidism group, 50.0%; subclinical hypothyroidism group, 19.0%; normal thyroid function group, 20.4%) without statistical significance (P=0.372). CONCLUSIONS: The prevalence of overt and subclinical hypothyroidism in constipated patients was very low. The colonic transit time is not affected by thyroid function.

BACKGROUND/AIMS: Constipation is a well-recognized gastrointestinal symptom in patients with untreated hypothyroidism. Although thyroid function tests are recommended to exclude hypothyroidism in patients with constipation, there have been no reports to determine the causal relationship between thyroid function and constipation. The aim of this study was to determine the prevalence of hypothyroidism in constipated patients and the clinical features of constipation associated with hypothyroidism. METHODS: A total of 1,481 constipated patients were included. These patients were divided into overt hypothyroidism, subclinical hypothyroidism, and normal thyroid function groups based on thyroid function tests. We reviewed the clinical presentation, anorectal function, colonic transit time, defecographic findings, and response to biofeedback therapy. RESULTS: The prevalence of overt and subclinical hypothyroidism was 0.41% (men, 0.36%; women, 0.53%) and 1.76% (men, 1.28%; women 2.03%), respectively. There were no differences in total or segmental colonic transit times and subtypes of constipation among the normal thyroid function (n=54), overt hypothyroidism (n=4), and subclinical hypothyroidism groups (n=21). On anorectal manometry, the prevalence of dyssynergic defecation did not differ between the three groups. Rectal hyposensitivity was more frequent in the overt hypothyroidism group (overt hypothyroidism group, 50.0%; subclinical hypothyroidism group, 19.0%; normal thyroid function group, 20.4%) without statistical significance (P=0.372). CONCLUSIONS: The prevalence of overt and subclinical hypothyroidism in constipated patients was very low. The colonic transit time is not affected by thyroid function.

El estreñimiento patología de múltiples orígenes, con alta prevalencia en la población occidental, para su estudios, el tránsito colónico (TC) con marcadores radio-opacos, según Hinlton, es un examen simple, reproducible. En el Servicio de Gastroenterología del Hospital Carlos J. Bello, de la Cruz Roja Venezolana, se seleccionaron 80 pacientes, 20 sanos en el grupo control, y 60 con diagnósticos de Estreñimiento Crónico, para la aplicación de esta prueba, en periodo comprendido entre Mayo 2005 - Julio 2006. Se observo que el uso de el Transito Colónico en el diagnostico de Estreñimiento Crónico, no debe considerarse como prueba de primera línea, el resultado de la misma se ve influenciado por otros factores que contribuyen con el estreñimiento.
Constipation pathology of multiples origins, with high prevalence in the western population, to study it, the colonic transit (CT) according to Hinlton, is a simple examination, with radio-opaque markers. In the Service of Gastroenterology of Hospital Carlos J. Bello, of the Venezuelan Red Cross two groups were selected, 60 patients with constipation and 20 patients as control group. A first group, with diagnosis of constipation, was included for the application of this test in the period between May 2005 to Julio 2006. We observed that the use of colonic transit in the diagnosis of chronic constipation, does not have to be considered a test of first line, the result of such test is influenced by other factors that contribute with constipation.
ABSTRACT
0.5 or close to 1.0,suggesting marker retained many parts of the sigmoid colon and rectum,FOOC possibility.Normal group,constipation group colon 48,72 hour markers district retention contrast,have significant differences.TI as the STC's kinetic parameters can be used as the difference between STC and the simple and reliable indicators FOOC.17 cases in this group(accounting for 68%)FC children with TI in 48 h,72 h were 0.5,in line with the characteristics of FOOC.Conclusion The results of this study showed that colonic transit time checks can be more accurately reflect the normal function of colonic transit may be the evaluation of patients with functional constipation colonic transit weaken the seriousness of the correct and reasonable to carry out sub-type of clinical treatment of important guiding significance.
ABSTRACT
Many hemodialysis patients suffer from constipation. The increased incidence of constipation in long-term dialysis patients is based mainly on self-reported data. So, we conducted a survey on 10 hemodialysis patents with constipation by using total and segmental colonic transit time of radio-opaque markers. Segmental colonic transit times were calculated separately for 3 segments of the colon (right, left, and rectosigmoid) and total transit time, which was the sum of all 3 segment times. On results, colonic transit time was significantly prolonged in hemodialysis patient than in healthy control (42.2+/-20.11 versus 10.57+/-12.8 hour; p<0.0001). Increased colonic transit times in the right and especially rectosigmoid segments, but not the left segment, contributed to the prolongation in total colonic transit time. In conclusion, we suggest that colonic transit time measurement is helpful to tailor therapy because it helps us determine the prolonged segment of the colon in hemodialysis patients with constipation.
