摘要
Chronic constipation （CC） is one of the most common functional gastrointestinal diseases. At present， the overall therapeutic effect of CC is still not satisfactory worldwide， which seriously affects the quality of life and social function of patients. The etiology and pathophysiological mechanism of constipation are still unclear. It involves comprehensive factors such as heredity， social psychology， diet， intestinal flora imbalance， intestinal motility disorder， visceral sensitivity change， pelvic floor muscle group dysfunction and enteric nervous system （ENS） disorder. Among them， the abnormal factors of the brain-gut-microbiome axis are particularly significant. The brain-gut-microbiome axis is a complex network of interactions between the intestine and the brain， integrating and coordinating the physiological functions and pathological processes of the gastrointestinal tract. Microorganisms in the intestinal lumen play an important role in it， and can communicate with the intestinal tract and the central nervous system through nerve， endocrine and immune pathways. As a key brain-gut peptide in the regulation pathway of the brain-gut-microbiome axis， 5-hydroxytryptamine （5-HT） is involved in the regulation of gastrointestinal motility， sensation and secretion. The abnormal conduction of the 5-HT signaling pathway is closely related to the occurrence and development of constipation. Traditional Chinese medicine（TCM） is a unique precious resource in China， which has good curative effects and safety. In recent years， it has received extensive attention in the treatment of constipation. TCM and active ingredients， acupuncture and massage specifically regulate 5-HT signal transmission， so that the expressions of related molecules tend to be suitable for individual disease state levels to effectively improve constipation symptoms， with unique advantages. Therefore， this study used ''constipation''， ''intestinal flora''， ''5-HT''， and ''traditional Chinese medicine'' as the keywords to search PubMed， China National Knowledge Infrastructure （CNKI） and other literature databases. The correlation between 5-HT and constipation as well as brain-gut-microbiome axis and the research progress of TCM intervention in the 5-HT signaling pathway in the treatment of constipation were reviewed in order to explore the potential therapeutic value of 5-HT system in this disease and provide references for subsequent research.

ObjectiveTo research the mechanism underlying the effect of raw and processed Aurantii Fructus Immaturus switched to Zhishi Shaoyaosan （ZSS） on constipation-predominant irritable bowel syndrome （C-IBS） rats via the brain-gut-microbiota axis. MethodEighty rats were randomly divided into the blank， model， positive drug （pinaverium bromide， 15.625 mg·kg-1）， raw ZSS， stir-fried ZSS， bran-fried ZSS， charcoal-fried ZSS and finished ZSS groups （3.75 g·kg-1）， with 10 rats in each group. Except for the blank group， which received intragastric administration of 0.9% sodium chloride solution at room temperature， all other groups were administered the ice solution at 0 to 4 ℃ （2 mL·d-1， for a total of 14 d） to establish the C-IBS rat model. The fecal water content and the propulsion rate of small intestine were detected after 14 d of continuous drug administration. The levels of 5-hydroxytryptamine （5-HT）， vasoactive intestinal peptide （VIP）， neuro-peptide Y （NPY）， calcitonin gene-related peptide （CGRP）， substance P （SP）， diamine oxidase （DAO） and D-lactic acid （D-LA） were detected by enzyme linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to observe the changes in colonic pathological injury in each group. The expression levels of cyclic adenosine monophosphate （cAMP）， protein kinase A （PKA） and aquaporin-3 （AQP3） mRNA in colon tissues were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and the protein expressions of VIP and AQP3 in colon tissues were detected by Western blot. The content of short chain fatty acids （SCFAs） was determined by gas chromatography-mass spectrometry. ResultCompared with the blank group， the fecal water content and intestinal propulsion rate of rat in the model group were significantly decreased （P<0.01）， and the levels of 5-HT， VIP， CGRP and SP in serum were significantly increased. Simultaneously， the NPY levels significantly decreased （P<0.01）， the levels of DAO and D-LA in plasma were significantly increased （P<0.01）， and the mucosal epithelium of colon tissue was slightly damaged， with reduced goblet cells and significantly reduced luminal granules. The mRNA expression levels of AQP3， cAMP and PKA and the protein expression levels of AQP3 and VIP in colon tissue were significantly decreased （P<0.05， P<0.01）. The total amount of SCFAs in feces showed an obvious decreasing trend， with the contents of acetic acid， isobutyric acid， isovaleric acid， valeric acid and caproic acid decreased significantly， while the contents of propionic acid and butyric acid increased significantly （P<0.05， P<0.01）. Compared with the model group， the treatment groups increased the intestinal propulsion rate， improved the intestinal mucosal barrier function， and adjusted the level of serum brain-gut peptide in C-IBS rats （P<0.05， P<0.01）. The expression levels of AQP3， cAMP， PKA mRNA and VIP， AQP3 protein in colon tissue of rats in all treatment groups were increased. All the treatment groups had a significant downregulation of the content of SCFAs except for isobutyric acid in rat feces， and the effect of ZSS prepared by the bran-fried Aurantii Fructus Immaturus was superior than that of other ZSS. ConclusionThe raw and processed Aurantii Fructus Immaturus switched to ZSS could influence the brain-gut-microbiota axis to treat C-IBS rats and it is more reasonable to use bran-fried Aurantii Fructus Immaturus in ZSS.

Objective:To compare the clinical efficacy of ileocecal-preserving laparoscopic subtotal colectomy, antegrade peristaltic ascending colorectal anastomosis with antiperistalsis cecorectal anastomosis in the treatment of severe slow transit constipation.Methods:The clinical data of 42 patients with severe slow transit constipation undergoing surgery in Shulan (Hangzhou) Hospital from Jan 2016 to Oct 2021 were retrospectively analyzed. All 42 patients underwent ileocecal-preserving laparoscopic subtotal colectomy. Among them, 25 patients underwent antegrade peristaltic anastomosis of ascending colon and rectum, 17 patients underwent antiperistaltic anastomosis of cecum and rectum.Results:There was no significant difference in the operation time and hospitalization time between the two groups ( t=-0.464, P=0.645; t=0.010, P=0.992); Wexner constipation scores in both groups were significantly reduced at 6 and 12 months after surgery. There was no significant difference in the Wexner constipation scores ( t=-1.181, P=0.240; t=-1.717, P=0.090), the number of bowel movenents per day ( t=0.179, P=0.860; t=0.545, P=0.590) and stool shapes scores ( t=-0.316, P=0.750; t=0.447, P=0.660) between the two groups at 6 and 12 months after surgery. Gastrointestinal quality of life index scores in the antegrade peristaltic anastomosis group were significantly higher than those in the antiperistalsis anastomosis group at 6 and 12 months after surgery ( t=4.329, P<0.05; t=3.988, P<0.05), while abdominal pain scores were significantly lower than those in the antiperistalsis anastomosis group ( t=-4.386, P<0.05; t=-5.740, P<0.05). Conclusions:For patients with severe slow transit constipation, ileocecal-preserving laparoscopic subtotal colectomy has good surgical safety and near-to-medium-term clinical efficacy, whether it is antegrade peristaltic ascending colorectal anastomosis (the stump of the ascending colon is turned from front to back) or antiperistalsis cecorectal anastomosis. The antegrade peristaltic ascending colorectal anastomosis has lower abdominal pain score and better gastrointestinal quality of life than antiperistalsis cecorectal anastomosis, which should be recommended first. During the operation, the ileocolic mesentery should be fully separated to the root of mesentery and the ileocecal part should be turned from front to back to avoid the occurrence of mesenteric vascular torsion and small intestinal obstruction.

ObjectiveTo clarify the relationship between intestinal flora and intestinal motility in rats with slow transit constipation （STC） and qi stagnation syndrome by conducting a pseudo-sterile experiment and fecal microbiota transplantation （FMT） technology. MethodsTwenty-four Wistar rats were randomly divided into normal group （n=6）， STC with qi stagnation pattern group （n=6） and pseudo-sterile group （n=12）. In the STC group with qi stagnation pattern， 3 mg/kg of loperamide suspension by intragastric administration combined with tail clamping stimulation were performed to establish the rat model of STC with qi stagnation pattern. After successful modeling， fresh feces from the rats in the STC with qi stagnation pattern group and the normal group were collected to prepare 100 mg/ml of fecal bacterial suspension. In the pseudo-sterile group， the antibiotic cocktail method was used （a mixed antibiotic suspension containing bacitracin， streptomycin sulfate， and neomycin sulfate at 20 mg/ml each was administered intragastrically） to establish pseudo-sterile rats model. After successful modeling， the rats were randomly divided into normal fecal bacterial liquid group and STC with qi stagnation pattern fecal bacterial liquid group， with six rats in each group， and then were given 10 ml/kg of the prepared corresponding rat fecal bacterial suspension by gavage. Rats in STC with qi stagnation pattern group were given an equal volume of sterile water by gavage. All groups were administered once a day for 7 consecutive days. The small intestinal propulsion rate of the STC with qi stagnation pattern group， the normal fecal bacterial liquid group， and STC with qi stagnation pattern fecal bacterial liquid group were compared. ELISA method was used to detect serum 5-hydroxytryptamine （5-HT） levels. Immunohistochemistry was used to detect the positive expression levels of 5-hydroxytryptamine 3 receptor （5-HT3R） and 5-hydroxytryptamine 4 receptor （5-HT4R） in colon tissue. Western blot method was used to detect the protein expression levels of tryptophan hydroxylase 1 （TPH1）， tryptophan hydroxylase 2 （TPH2）， serotonin transporter （SERT）， and monoamine oxidase A （MAO-A） in colon tissue. ResultsCompared to those in the normal fecal bacterial liquid group， the small intestinal propulsion rate， serum 5-HT level， positive expression of 5-HT3R and 5-HT4R in colon tissue， and protein expression of TPH1， TPH2， SERT and MAO-A significantly decreased in the STC with qi stagnation pattern group and STC with qi stagnation pattern fecal bacterial liquid group （P＜0.05）. There was no statistically significant difference in the indicators between the STC with qi stagnation pattern group and STC with qi stagnation pattern fecal bacterial liquid group （P＞0.05）. ConclusionThe intestinal flora in STC rats with qi stagnation pattern can lead to a slowdown in intestinal transmission function， whose mechanism may be related to intestinal motility disorders affected by the synthesis， transport， metabolism and other pathways of 5-HT.

Objective@#To investigate the causal relationship between gut microbiota and constipation using Mendelian randomization (MR) method.@*Methods@#Genetic variation data of gut microbiota were obtained from the MiBioGen Consortium database. The genetic variation data of constipation were sourced from the IEU Open GWAS database. A forward MR analysis was performed using the inverse-variance weighted (IVW) method with 2 511 SNPs associated with gut microbiota as instrumental variables, and constipation as study outcome, and a reverse MR analysis was performed with 13 microbiota-associated SNPs as instrumental variables and gut microbiota as study outcome. The heterogeneity was assessed using the Cochran test, reverse causation of SNP were examined using MR Steiger test, and the horizontal pleiotropy was assessed using the MR-PRESSO test and MR-Egger regression. In addition, the robustness of the results was verified with the leave-one-out.@*Results@#Forward MR analysis results showed that an increased abundance of genus Coprococcus1 driven by host genetics was associated with a decreased risk of constipation (OR=0.791, 95%CI: 0.709-0.884), and increased abundance of phylum Bacteroidetes driven by host genetics was associated with an increased risk of constipation (OR=1.240, 95%CI: 1.102-1.394). Cochran test detected no heterogeneity (both P>0.05), MR Steiger test was not revealed reverse causation of SNP, and neither the MR-PRESSO test nor the MR-Egger regression revealed horizontal pleiotropy of instrumental variables (all P>0.05), and the leave-one-out method confirmed the robustness of results. Reverse MR analysis showed no association between gut microbiota and constipation (both P>0.05).@*Conclusion@#Genus Coprococcus1 and phylum Bacteroidetes in the gut microbiota are associated with constipation.

Objective: To investigate the laxative effect of reducing the number of daily doses of magnesium oxide (MgO), while maintaining the total daily dose of MgO in patients with good bowel movements.Patients and Methods: The retrospective analysis involved 11 patients with regular bowel movements who were prescribed MgO for constipation upon admission to a nursing care facility accompanied by home visits by a pharmacist. This investigation was conducted before and after reducing the number of daily doses from three to two, or from two to one, over a two-week period.Results: The number of bowel movements was 7.6 ± 3.4 and 6.6 ± 4.0 times for two weeks before and after the change in dosage frequency, respectively. The difference was not statistically significant (P=0.09). The Bristol Stool Form Scale was 3.9 ± 0.9 and 4.0 ± 0.9 two weeks before and after the change, respectively, which was not significant (P=0.93). Two weeks after the change, the MgO regimen remained unchanged and no on-demand laxatives were administered.Conclusions: The results suggest that reducing the number of daily doses of MgO does not affect its laxative action.

ObjectiveTo investigate the mechanism of Atractylodis Macrocephalae Rhizoma（AMR） in the treatment of slow-transmission constipation（STC） by observing the effects of AMR on short-chain fatty acids and intestinal barries in STC mice. MethodForty-eight male KM mice were randomly divided into blank group， model group， AMR low-， medium-， high-dose groups（2.5， 5， 10 g·kg-1） and mosapride group（2.5 mg·kg-1）. Except for the blank group， all groups were gavaged with loperamide suspension（5 mg·kg-1） twice daily for 14 d to construct the STC mouse model. At the same time， each drug administration group was given the corresponding drug by gavage for consecutive 14 d， the blank and model groups were gavaged with equal volume of distilled water. The effects of the treatment of AMR on body mass， defecation frequency， fecal water content and intestinal propulsion rate of mice were observed， the pathological changes of mouse colon were observed by hematoxylin-eosin（HE） staining and periodic acid-Schiff（PAS） staining， the levels of gastrin（GAS） and motilin（MTL） in serum were detected by enzyme-linked immunosorbent assay（ELISA）， gas chromatography-mass spectrometry（GC-MS） was used to detect the contents of short-chain fatty acids（SCFAs） in mouse feces， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） and Western blot were used to determine the mRNA and protein expression levels of zonula occludens-1（ZO-1）， Occludin， and Claudin-1 in the colon of mice. ResultCompared with the blank group， the body mass， defecation frequency， fecal water content and intestinal propulsion rate of mice in the model group were significantly decreased（P<0.05， P<0.01）， the arrangement of colonic tissues was disordered， and the number of goblet cells was reduced， the levels of GAS and MTL in serum were significantly decreased（P<0.01）， and the levels of SCFAs in the feces were on a decreasing trend， with the contents of acetic acid， propionic acid， butyric acid， isobutyric acid and valeric acid were significantly decreased（P<0.05， P<0.01）， the mRNA and protein expression levels of ZO-1， Occludin and Claudin-1 in the colonic tissues were significantly decreased（P<0.01）. The above results suggested that STC mouse model was successfully constructed. Compared with the model group， the body mass， defecation frequency， fecal water content and intestinal propulsion rate of mice in AMP administration groups all increased significantly（P<0.05， P<0.01）， the mucosal layer of the colonic tissues was structurally intact without obvious damage， and the number of goblet cells increased， serum levels of GAS and MTL were significantly increased（P<0.01）， the contents of SCFAs in the feces were all on a rising trend， with the contents of acetic， propionic， butyric and isobutyric acids rising significantly（P<0.05， P<0.01）， the mRNA and protein expression levels of ZO-1， Occludin and Claudin-1 in the colonic tissues were significantly increased（P<0.05， P<0.01）. ConclusionAMR is able to improve the constipation symptoms in STC mice， and its mechanism may be related to increasing the contents of SCFAs in the intestine as well as promoting the mRNA and protein expression levels of ZO-1， Occludin and Claudin-1 in the colon.

OBJECTIVE To investigate the improvement effects of Runchang granules on the constipation in mice and its potential mechanism. METHODS The mice were randomly divided into normal control group， model group， Runchang granules low-dose and high-dose groups （5， 10 g/kg）， mosapride group （0.003 g/kg， positive control）， with 6 mice in each group. The latter 4 groups were given loperamide intragastrically （0.004 g/kg）， twice a day， for 3 consecutive days. Normal control group and model group were given purified water intragastrically， and administration groups were given relevant medicine intragastrically for 7 consecutive days. After the last medication， fecal moisture content and intestinal motility of mice were determined， while the structures of colon and ileum， and the secretion of colonic mucus were observed. Protein expressions of tyrosine kinase receptor （c-kit）， mucin 2 （MUC2） and stem cell factor （SCF） were determined in colon； meanwhile， the mRNA expression levels of inflammatory factors [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， inducible nitric oxide synthase （iNOS）] as well as factors related to promoting intestinal motility [neuronal nitric oxide synthase （nNOS）， smooth muscle myosin light chain kinase （smMLCK）， 5-hydroxytryptamine 4 receptor （5-HT4R）， MUC2， SCF， c-kit] were determined. RESULTS Compared with model group， the fecal water content， intestinal propulsion rate， protein expression of c-kit in colon， relative expressions of MUC2 and SCF protein， and mRNA expressions of factors related to promoting intestinal motility （except for nNOS and SCF in Runchang granules low-dose group） were all increased significantly in Runchang granules low-dose and high-dose groups， and mosapride group （P＜0.05 or P＜0.01）. mRNA expression levels of inflammatory factors were decreased significantly（P＜0.05 or P＜0.01）. Both colon and ileum injuries improved， and the secretion of colon mucus was increased significantly in Runchang granules high-dose group （P＜0.01）. CONCLUSIONS Runchang granules have laxative effect and can improve constipation in mice， and its mechanism may be related to the promotion of the secretion of colon mucus and MUC2 expression， and the activation of SCF/c-kit signaling pathway.

Objective To observe the effects of Shengxue Tongbian Granules on colonic myoelectricity and Ca2+/CaM/MLCK signaling pathway in rats with slow transit constipation(STC)of blood deficiency and intestinal dryness syndrome;To explore its mechanism for the treatment of STC.Methods The STC model of blood deficiency and intestinal dryness syndrome was established by intragastric administration of loperamide combined with tail bloodletting.The rats were divided into control group,model group,mosapride citrate group and Shengxue Tongbian Granules group,with 8 rats in each group.The administration group was given corresponding drugs by gavage for 14 days.The general condition of rats before and after treatment was observed,the fecal water content was detected,the slow wave frequency,amplitude,and coefficient of variation of colonic electromyography were detected using a biological function experimental system,and intestinal propulsion rate was detected.HE staining was used to observe the pathological changes of colon tissue,the concentration of Ca2+ in colonic smooth muscle cells was detected by colorimetry,the expression of Cx43,calmodulin(CaM),myosin light chain kinase(MLCK)and p-MLC20 in smooth muscle tissue were detected by Western blot.Results Compared with the control group,the body mass,fecal water content and intestinal propulsion rate of rats in the model group decreased(P<0.01),the slow wave frequency of colonic electromyography slowed down,the coefficient of variation of frequency increased(P<0.01),and the amplitude and coefficient of variation of slow wave increased(P<0.01);colonic mucosal structure was damaged,with visible inflammatory changes and significant erosion,and the concentration of Ca2+ and the expressions of Cx43,CaM,MLCK,p-MLC20 proteins in colonic smooth muscle cells were significantly decreased(P<0.01).Compared with the model group,the body mass,fecal water content and intestinal propulsion rate of the rats in the mosapride citrate group and the Shengxue Tongbian Granules group significantly increased(P<0.05,P<0.01),the slow wave frequency of colonic electromyography increased and the coefficient of variation of frequency decreased(P<0.01),and the slow wave amplitude and amplitude variation coefficient decreased(P<0.05,P<0.01);the colonic mucosal structure was relatively intact,the erosion situation was improved,and the Ca2+ concentration,Cx43,CaM,MLCK and p-MLC20 protein expressions in colonic smooth muscle cells significantly increased(P<0.01).Conclusion Shengxue Tongbian Granules can improve defecation symptoms and promote colonic motility in STC rats with blood deficiency and intestinal dryness syndrome,which may be related to regulating colonic myoelectric rhythm and activating Ca2+/CaM/MLCK signaling pathway.
摘要
Constipation is a disorder of the gastrointestinal (GI) and some of the main etiological mechanisms are directly related to changes in GI physiology. The capacity to carry out paired assessments and measure GI parameters under the influence of constipation is a relevant point in selecting a suitable methodology. We aimed to perform a non-invasive investigation of gastrointestinal motility in constipated rats using the alternating current biosusceptometry system (ACB). The animals were split into two groups: the pre-induction stage (CONTROL) and post-induction loperamide stage (LOP). We assessed GI motility parameters using the ACB system. Colon morphometric and immunohistochemical analyses were performed for biomarkers (C-kit) for interstitial cells of Cajal (ICC). Our results showed a significant increase in gastrointestinal transit in the LOP group in addition to a reduction in the dominant frequency of gastric contraction and an arrhythmic profile. A change in colonic contractility profiles was observed, indicating colonic dysmotility in the LOP group. We found a reduction in the number of biomarkers for intestinal cells of Cajal (ICC) in the LOP group. The ACB system can evaluate transit irregularities and their degrees of severity, while also supporting research into novel, safer, and more efficient treatments for constipation.

Objective: Dyssynergic defaecation (DD) is an important cause of chronic constipation. In patients where conservative treatments fail, injections of botulinum toxin A (BTX-A) into the puborectalis and anal sphincter muscles can be effective. Complications of this procedure are reported to be rare and generally mild. This study aimed to identify the complication rates and short- to medium-term success rates of BTX-A injections as a treatment for DD. Methods: A retrospective review was conducted on patients diagnosed with DD who had undergone BTX-A injections at a functional colorectal unit. Patient demographics, manometric assessment, conservative management, and injection technique were collected through a chart review. Subjective patient reports and comparison of pre- and postprocedure symptom scores were used to determine efficacy. Results: The 21 patients included (24 procedures, with 3 patients receiving BTX-A on two separate occasions) all received stool modification and dietary advice, and 20 patients underwent pelvic floor physiotherapy, averaging 8 sessions. The injections were universally applied under general anesthetic, primarily targeting the anal sphincter and/or puborectalis muscles. There were 6 reports of faecal urge/incontinence, with all but one being resolved within weeks. The BTX-A injection was subjectively reported as beneficial in 19 cases, averaging 4.7 months (range 1-32) of improvement. Only 2 were sustained beyond 12 months. Despite overall improvements in symptom scores from pre- to postprocedure, none were statistically significant. Conclusion: Following a course of conservative management, the BTX-A injection appears to be a safe treatment for DD, but only has short term efficacy. (AU)

ABSTRACT Background: Functional constipation (FC) is a common global high prevalence issue in children. Objective: The purpose of the present study is to evaluate the effect of visceral manipulation (VM) on children with chronic interacble FC unresponsive to the standard treatment. Methods: This study was conducted as a randomized, single-blind controlled trial. Fifty-two children with refractory chronic functional constipation unresponsive to the standard medical treatment were randomly allocated to two groups of 26 control (standard medical care (SMC)) and 26 intervention (SMC with VM) for 4 weeks. Abdominal pain, painful defecation, stool consistency, defecation frequency, and the dose of oral laxative were evaluated before and after the treatment period using the Pain Rating Scale, Bristol stool form scale, and patient/parents report. Results: At the end of treatment, except for the dose of oral laxative in the control group, all of the results showed a significant difference in both groups (P<0.05). The dose of oral laxative in the intervention group decreased significantly (P<0.05), however, no significant change was observed in the control group (P>0.05). In the intervention group comparison, statistically significant differences were found in all variables except the Bristol stool form scale (P<0.05). The Bristol stool form scale after treatments was not different when the groups were compared (P=0.32), but the number of subjects who had normal stool consistency was significantly increased in the intervention group than in the control group (P<0.05). Conclusion: VM can be considered as a possible treatment without side effects besides SMC for the management of chronic FC. Further studies are needed to investigate the long-term effect of VM.
RESUMO Contexto: A constipação funcional (CF) é um problema comum de alta prevalência global em crianças. Objetivo: O objetivo do presente estudo é avaliar o efeito da manipulação visceral (MV) em crianças com CF crônica intratável, não responsiva ao tratamento padrão. Métodos: Este estudo foi conduzido como um ensaio clínico randomizado, controlado e cego. Cinquenta e duas crianças com CF crônica refratária, não responsivas ao tratamento médico padrão, foram randomicamente alocadas em dois grupos de 26 controle (cuidados médicos padrão (CMP)) e 26 intervenção (CMP com MV) por 4 semanas. Dor abdominal, defecação dolorosa, consistência das fezes, frequência de defecação e dose de laxante oral foram avaliadas antes e após o período de tratamento usando a Escala de Avaliação da Dor, Escala de Forma das Fezes de Bristol e relato do paciente/pais. Resultados: No final do tratamento, exceto pela dose de laxante oral no grupo controle, todos os resultados mostraram uma diferença significativa em ambos os grupos (P<0,05). A dose de laxante oral no grupo de intervenção diminuiu significativamente (P<0,05), entretanto, nenhuma mudança significativa foi observada no grupo controle (P>0,05). Na comparação do grupo de intervenção, diferenças estatisticamente significativas foram encontradas em todas as variáveis, exceto na Escala de Forma das Fezes de Bristol (P<0,05). A Escala de Forma das Fezes de Bristol após os tratamentos não foi diferente quando os grupos foram comparados (P=0,32), mas o número de indivíduos com consistência fecal normal aumentou significativamente no grupo de intervenção em comparação com o grupo controle (P<0,05). Conclusão: A MV pode ser considerada como um possível tratamento sem efeitos colaterais além dos CMP para o manejo da CF crônica. Mais estudos são necessários para investigar o efeito de longo prazo da MV.
摘要
Abstract Introduction Constipation is a common clinical condition, particularly among cancer patients. Objective To assess the prevalence and severity of CF in women with high-grade intraepithelial neoplasia (HSIL) and cervical cancer (CC), as well as the impact of this condition on their daily lives. Methods A cross-sectional study was conducted at a tertiary cancer center. To assess the presence and severity of constipation, the Rome IV criteria, and the Constipation Scoring System (CSS) were used. To assess the impact of constipation on daily life, the Visual Analogue Scale (VAS) was used. Results The study included 153 patients with HSIL or CC, with a median age of 44 (IQR 35-56) years. Constipation was reported in 54 (35.3%) patients, 33 (61.1%) of those with HSIL, and 21 (38.9%) of those with CC. In constipated patients, the median number of positive Rome IV criteria items was 3 (IQR 2-5). "Irregular or hard stools" was the most common complaint, affecting 41 (75.9%) of the patients. In patients with CC, the use of analgesic medications was associated with constipation (p = 0.016). There is no link between constipation and invasive cancer (p = 0.492). Constipation had a daily impact of 7.5 (IQR 4.75-9), with no relationship between VAS and clinical diagnosis (HSIL or CC) [7 (IQR 3-9) X 8 (5-9.5), p-value = 0.536] The more severe the constipation, the more disturbing it is to these women's daily lives. Conclusion Constipation is common in women with cervical lesions, affecting their daily lives regardless of their severity.
摘要
Context: Hirschsprung's disease (HD) is one of the commonest problems requiring surgery in children. More than 95% of children present during new-born period, when they are treated with leveling colostomy and are followed with pull-through surgery a few months later, once the child has gained adequate weight to withstand a major surgery. The commonest pull through surgery done is the Duhamel retro-rectal pull-through (DRPT) repair. Settings and Design: This is a retrospective study of children who presented to one unit in our institute, a tertiary care referral hospital for children less than 12 years, with HD and underwent DRPT procedure during the period between July 2017 to June 2020. The children were evaluated after three years of follow-up for fecal incontinence and constipation. The study was conducted in children diagnosed with classical segment recto-sigmoid HD who underwent surgery. The children who were diagnosed with HD other than classical segment, who underwent primary pull through surgery and who underwent other repairs for HD were excluded from the study. Results: Thirty-two children underwent DRPT procedure during the study period. Of them, five (15.6%) children were lost on follow-up and one (3.1%) child had expired in the immediate post-operative period. Twenty-six children were included in the study. The bowel function score was calculated. The mean age of definitive surgery was 4.2 years. The follow-up period was a minimum of three years. Only two children had a "good" score of eighteen and above. Nineteen children had a "fair" score of 13-17. Five children had a "poor" score of less than thirteen, and among them, two had a "very poor" score of less than nine. The mean BFS was 13.72. Conclusions: Functional outcomes following Duhamel procedure are satisfactory, with 7.7% of children are in the fringe of requiring another surgery for constipation and pseudo-incontinence. (AU)

ABSTRACT Background: Functional constipation and enuresis frequently coexist. Constipation treatment often results in resolution or improvement of the enuresis. However, besides the classical presentation, patients can present with occult constipation (OC) diagnosed in complementary evaluation; in addition, semi-occult constipation (SOC) can be detected by means of a detailed questionnaire. Objective: To quantify OC and SOC frequency in children with monosymptomatic or non monosymptomatic enuresis (MNE or NMNE). Methods: Otherwise healthy children/adolescents, with enuresis refractory to behavioral therapy and denying constipation after simple questions, answered a structured bowel habit questionnaire and were submitted to a plain abdominal radiological exam. Constipation was classified considering the Boston diagnostic criteria (to allow diagnosis at initial stages), and fecal loading in the X-ray quantified ≥10 by the Barr score. Children with constipation received a standardized treatment (except 26 "pilot" children). Results: Out of 81 children, 80 aged 9.34±2.07 years, 52.5% male, were diagnosed with constipation: 30 OC, 50 SOC; 63.75% had MNE, 36.25% NMNE (six NMNE without behavioral therapy). Demographic data and the Barr score were similar for OC and SOC, but SOC children experienced significantly more constipation complications (retentive fecal incontinence and/or recurrent abdominal pain). Not showing the Bristol Stool Scale (BSS) to 24 "pilot" children, or absence of constipation symptoms accompanying BSS predominantly type 3, in 13 children, did not significantly impact the detection of constipation by the Barr score. Children identifying BSS 3 or ≤2 had similar results. Twenty-eight children, with adequate follow-up after treatment, improved or recovered from constipation at 44 of their 52 follow-up visits. Conclusion: In patients with MNE or NMNE refractory to behavioral therapy, and who initially denied constipation after simple questions, a detailed questionnaire based on the Boston diagnostic criteria detected SOC in 61.7%, and the radiological Barr score revealed fecal loading (OC) in 37.0% of them.
RESUMO Contexto: Constipação funcional e enurese frequentemente coexistem. Tratamento da constipação geralmente resulta em cura ou melhora da enurese. Entretanto, além da apresentação clássica, pode ocorrer constipação oculta (CO), diagnosticada por exame subsidiário; ademais, ao aplicar questionário detalhado, pode-se detectar constipação semioculta (CSO). Objetivo: Obter as frequências de CO e CSO em crianças com enurese mono- ou não monossintomática (EMN ou ENMN). Métodos: Crianças/adolescentes saudáveis, exceto por enurese refratária à terapia comportamental, e que negavam constipação após perguntas simples, respondiam a questionário estruturado sobre hábito intestinal, e realizavam radiografia simples de abdômen. A constipação foi classificada considerando os critérios diagnósticos de Boston (que permitem diagnóstico em fases iniciais) e retenção fecal na radiografia quantificada ≥10 pelo escore de Barr. As crianças com constipação receberam tratamento padronizado (exceto 26 crianças "piloto"). Resultados: Das 81 crianças, 80 com idade 9,34±2,07 anos, 52,5% masculinas, foram diagnosticadas com constipação: 30 CO, 50 CSO; 63.75% tinham EMN, 36.25% ENMN (6 ENMN sem terapia comportamental). Os dados demográficos e o escore de Barr foram semelhantes para CO e CSO, mas as crianças com CSO apresentaram significativamente mais complicações de constipação (incontinência fecal retentiva e/ou dor abdominal recorrente). A não apresentação da Escala Fecal de Bristol (EFB) para 24 crianças "piloto", ou ausência de sintomas de constipação acompanhando EFB predominantemente do tipo 3, em 13 crianças, não teve impacto significativo na detecção de constipação pelo escore de Barr. Crianças que identificaram EFB 3 ou ≤2 tiveram resultados semelhantes. Vinte e oito crianças, com acompanhamento adequado após o tratamento, melhoraram ou se recuperaram da constipação em 44 de seus 52 retornos. Conclusão: Em pacientes com EMN ou ENMN refratária à terapia comportamental, e que inicialmente negavam constipação após perguntas simples, questionário baseado nos critérios diagnósticos de Boston detectou CSO em 61.7%, e o escore radiológico de Barr revelou retenção fecal (CO) em 37% deles.
摘要
Introducción: El prolapso rectal completo es la invaginación de las capas del recto a través del canal anal y su protrusión fuera de este. Su incidencia es de 2,5 por 100 000 habitantes con predominio en mujeres de edad avanzada. Es una afección de curso crónico y benigno, cuya presentación clínica y endoscópica es tan variable que puede confundirse con otras entidades como con el cáncer colorrectal. Objetivo: Presentar el caso de una paciente femenina, operada de prolapso rectal completo en la provincia de Cienfuegos. Presentación de caso: Se presenta una paciente femenina de 76 años de edad, blanca, de procedencia rural que acude a la consulta y refiere que lleva 12 días sin defecar. Además, presenta dolor, sangramiento rectal no activo y una masa que protruía a través de la región anal sugestiva al examen físico de un prolapso rectal completo. El tacto rectal confirma el diagnóstico. Se realiza reducción quirúrgica del prolapso por técnica de Delorme. Actualmente lleva 6 meses de operada con evolución favorable. Por lo poco frecuente de esta entidad se considera de interés científico su publicación. Conclusión: Esta entidad es poco común en el entorno médico, el gran cambio que causa en el nivel de vida de aquellos que la portan y sus complicaciones hace que requiera un tratamiento rápido y oportuno(AU)
Introduction: Complete rectal prolapse is the invagination of the rectal layers through the anal canal and its protrusion out of it. Its incidence is 2.5 per 100,000 inhabitants, predominantly in elderly women. It is a chronic and benign condition, whose clinical and endoscopic presentation is so variable that it can be confused with other entities, such as colorectal cancer. Objective: To present the case of a female patient who underwent surgery for complete rectal prolapse in the province of Cienfuegos. Case presentation: A 76-year-old female patient, white, from a rural area, came to the clinic and reported that she had not defecated for 12 days. In addition, she presents pain, nonactive rectal bleeding and a mass protruding through the anal region suggestive, on physical examination, of a complete rectal prolapse. Digital rectal examination confirmed the diagnosis. Surgical reduction of the prolapse was performed using the Delorme technique. She has undergone surgery for 6 months now, with favorable evolution. Due to the rarity of this entity, its publication is considered as scientifically interesting. Conclusion: This entity is uncommon in the medical environment. The great change that it causes in the living standards of those who carry it and its complications make it require a quick and timely treatment(AU)
