THE COLONIC TRANSIT TEST IN THE ASSESSMENT OF CHRONIC CONSTIPATION

In order to assess colonic motility of chronic constipation, colonic transit test was carried out in 34 patients with chronic constipation and in 20 healthy subjects. 20 radiopaque markers are ingested at 8 am before the day test, and plain abdominal films were obtained at 24 h, 48 h and 72 h. The normal value of colonic transit test was 16(80%), or more markers passed after 72 h. By means of transit time study, 34 constipated patients were classified into 2 groups: 12 normal transit patients and 22 slow transit patients. There was no difference in colonic transit time between normal transit patients and controls (P>005). Patients with slow transit had more markers left in right colon, left colon and rectosigmoid colon at 48 h (P<001, respectively) and 72 h (P<001, respectively). According to the transit index, 22 slow transit patients were divided into 3 types: 10 cases colonic stasis, 8 cases outlet obstruction and 4 cases colorectal stasis. The study suggests that chronic constipated patients have abnormalbilities of colonic transit.

Subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy for the treatment of slow transit constipation in an aged population:A retrospective control study

AIM To compare the efficacy,improved quality of life,and prognosis in patients undergoing either subtotal colonic bypass with antiperistaltic cecoproctostomy(SCBAC) or subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy(SCBCAC) for the treatment of slow transit constipation.METHODS Between October 2010 and October 2014,aged patients with slow transit constipation who were hospitalized and underwent laparoscopic surgery in our institute weredivided into two groups: the bypass group,15 patients underwent SCBAC,and the bypass plus colostomy group,14 patients underwent SCBCAC. The following preoperative and postoperative clinical data were collected: gender,age,body mass index,operative time,first flatus time,length of hospital stay,bowel movements(BMs),Wexner fecal incontinence scale,Wexner constipation scale(WCS),gastrointestinal quality of life index(GIQLI),numerical rating scale for pain intensity(NRS),abdominal bloating score(ABS),and ClavienDindo classification of surgical complications(CD) before surgery and at 3,6,12,and 24 mo after surgery.RESULTS All patients successfully underwent laparoscopic surgery without open surgery conversion or surgeryrelated death. The operative time and blood loss were significantly less in the bypass group than in the bypass plus colostomy group(P = 0.007). No significant differences were observed in first flatus time,length of hospital stay,or complications with CD > 1 between the two groups. No patients had fecal incontinence after surgery. At 3,6,and 12 mo after surgery,the number of BMs was significantly less in the bypass plus colostomy group than in the bypass group. The parameters at 3,6,12,and 24 mo after surgery in both groups significantly improved compared with the preoperative conditions(P < 0.05),except NRS at 3,6 mo after surgery in both groups,ABS at 12,24 mo after surgery and NRS at 12,24 mo after surgery in the bypass group. WCS,GIQLI,NRS,and ABS significantly improved in the bypass plus colostomy group compared with the bypass group at 3,6,12,and 24 mo after surgery(P < 0.05) except WCS,NRS at 3,6 mo after surgery and ABS at 3 mo after surgery. At 1 year after surgery,a barium enema examination showed that the emptying time was significantly better in the bypass plus colostomy group than in the bypass group(P = 0.007).CONCLUSION Laparoscopic SCBCAC is an effective and safe procedure for the treatment of slow transit constipation in an aged population and can significantly improve the prognosis. Its clinical efficacy is more favorable compared with that of SCBAC. Laparoscopic SCBCAC is a better procedure for the treatment of slow transit constipation in an aged population.

Proteomic analysis of down-regulated proteins in colonic mucosa of chronic slow transit constipation rats

Objective： To investigate the alternations of proteins in the colonic mucosa of chronic slow transit constipation （STC） rats with a 2-DE-based proteomic method and analyze the function of these down-regulated proteins so as to provide theoretical basis for the pathogenesis of intestinal mucosa of chronic STC rats. Methods： STC model was established by feeding rats with 8 mg/（kg＇d） diphenoxylate for 120 d. An experimental model of chronic STC rat was used for separation of proteomics from colonic mucosa using two-dimensional electrophoresis （2-DE）. Proteins altered in expressional level were identified by Image Master 2DElite, mass spectrometry, and bibliometrics were applied to identify the differential protein expression and their clinical s observed in the pathogenesis lgn of ificance and function were analyzed. Results： Obvious differential protein expression was STC, including mast cell protease （A1）, non-specific dipeptidase （A2） and chondrosome succinate dehydrogenase precursor （A3）. The expressions of A1, A2 and A3 were down-regulated in the gel graph of STC rats Conclusion： The down-regulation of chondrosome succinate dehydrogenase, mast cell protease as well as non-specific dipeptidase in rat colon suggests the functional impairment of the oxidoreduction of mitochondrion is very important in the genesis and development of STC. The immunological reaction of STC rats is weakened, and the function of digesting and absorbing protein may be damaged to some extent.

The Value of a Modified Colonic Transit Test in the Diagnosis of Chronic Constipation

Objectives To explore the value of performing a modified colonic transit test in the diagnosis of chronic constipation.Methods we retrospectively analyzed the results in 101 patients admitted to the MDT Outpatient Clinic of Subei People’s Hospital,Jiangsu Province,China,from July 1,2019,to July 31,2021.Patients were prohibited from using drugs and stimulant foods that could affect bowel motility for three days before and during the examination.We performed two abdominal X-rays at 6 and 72 hours after oral ingestion of the barium suspension to observe the residual condition of barium in the patient's colon.We then gave specific treatments based on the different types of constipation detected in the patients.Results Compared with patients with normal transit,patients with slow transit(P<0.001)and patients with rectal evacuation disorders had a significantly reduced stool frequency(P<0.05).The kappa coefficient of the modified colonic transit test compared to anorectal manometry in the diagnosis of functional defecation disorders(FDDs)was 0.649,indicating substantial consistency between the two methods.Conclusion The modified colonic transit test not only assesses colonic transit function and provides an initial determination of the type of constipation,but also shows the colon morphology,providing a reference for possible subsequent treatments.

Normal aspects of colorectal motility and abnormalities in slow transit constipation

Human colonic motility is a relatively difficult topic to investigate. However, the refinement of manometric techniques in recent years enabled us to study both the proximal and distal segments of the viscus. The present paper reviews our knowledge about normal aspects of colorectal motility in man and the abnormalities found in slow transit constipation (STC), one of the most frequent and difficult to treat subtypes of constipation. An internetbased search strategy of the Medline and Science Citation Index was performed using the keywords colon, colonic, colorectal, constipation, slow transit, motility, rectal, rectum in various combinations with the Boolean operators AND, OR and NOT. Only articles related to human studies were used, and manual cross-referencing was also performed. Most of colonic motor activity is represented by single nonpropagated contractions, rarely organized in bursts; this activity is maximal during the day, especially after waking and following meals. In addition, a specialized propagated activity with propulsive features is detectable, represented by high-and low-amplitude propagated contractions. In the severe form of constipation represented by the slow transit type, the above motor activity is completely deranged. In fact, both basal segmental activity (especially in response to meals) and propagated activity (especially that of high amplitude) are usually decreased, and this may represent a physiologic marker of this disorder. Human colonic motor activity is quite a complex issue, still only partly understood and investigated, due to anatomic and physiological difficulties. In recent years, however, some more data have been obtained, even in proximal segments. These data have helped in elucidating, although only in part, some pathophysiological mechanisms of chronic constipation, and especially of the STC subtype.

Preservation of superior rectal artery in laparoscopically assisted subtotal colectomy with ileorectal anastomosis for slow transit constipation

BACKGROUND Slow transit constipation(STC)has traditionally been considered as a functional disorder.However,evidence is accumulating that suggests that most of the motility alterations in STC might be of a neuropathic etiology.If the patient does not meet the diagnosis of pelvic outlet obstruction and poorly response to conservative treatment,surgical intervention with subtotal colectomy may be effective.The most unwanted complication of the procedure is anastomotic leakage,however,preservation of the superior rectal artery(SRA)may reduce its incidence.AIM To evaluate the preservation of the SRA in laparoscopically assisted subtotal colectomy with ileorectal anastomosis in STC patients.METHODS This was a single-center retrospective observational study.STC was diagnosed after a series of examinations which included a colonic transit test,anal manometry,a balloon expulsion test,and a barium enema.Eligible patients underwent laparoscopically assisted total colectomy with ileorectal anastomosis and were examined between January 2016 and January 2018.The operation time,blood loss,time to first flatus,length of hospital days,and incidence of minor or major complications were recorded.RESULTS A total of 32 patients(mean age,42.6 years)who had received laparoscopic assisted subtotal colectomy with ileorectal artery anastomosis and preservation of the SRA.All patients were diagnosed with STC after a series of examinations.The mean operative time was 151 min and the mean blood loss was 119 mL.The mean day of first time to flatus was 3.0 d,and the mean hospital stay was 10.6 d.There were no any patients conversions to laparotomy.Post-operative minor complications including 1 wound infection and 1 case of ileus.There was no surgical mortality.No anastomosis leakage was noted in any of the patients.CONCLUSION Laparoscopically assisted subtotal colectomy with ileorectal anastomosis and preservation of the SRA can significantly improve bowel function with careful patient selection.Sparing the SRA may protect against anastomosis leakage.

Consensus statement AIGO/SICCR:Diagnosis and treatment of chronic constipation and obstructed defecation(partⅠ:Diagnosis)

Chronic constipation is a common and extremely troublesome disorder that significantly reduces the quality of life,and this fact is consistent with the high rate at which health care is sought for this condition.The aim of this project was to develop a consensus for the diagnosis and treatment of chronic constipation and obstructed defecation.The commission presents its results in a "Question-Answer" format,including a set of graded recommendations based on a systematic review of the literature and evidence-based medicine.This section represents the consensus for the diagnosis.The history includes information relating to the onset and duration of symptoms and may reveal secondary causes of constipation.The presence of alarm symptoms and risk factors requires investigation.The physical examination should assess the presence of lesions in the anal and perianal region.The evidence does not support the routine use of blood testing and colonoscopy or barium enema for constipation.Various scoring systems are available to quantify the severity of constipation;the Constipation Severity Instrument for constipation and the obstructed defecation syndrome score for obstructed defecation are the most reliable.The Constipation-Related Quality of Life is an excellent tool for evaluating the patient's quality of life.No single test provides a pathophysiological basis for constipation.Colonic transit and anorectal manometry define the pathophysiologic subtypes.Balloon expulsion is a simple screening test for defecatory disorders,but it does not define the mechanisms.Defecography detects structural abnormalities and assesses functional parameters.Magnetic resonance imaging and/or pelvic floor sonography can further complement defecography by providing information on the movement of the pelvic floor and the organs that it supports.All these investigations are indicated to differentiate between slow transit constipation and obstructed defecation because the treatments differ between these conditions.

Use of a device that applies external kneading-like force on the abdomen for treatment of constipation

AIM: To evaluate the efficacy of a recently developed device that applies kneading-like motion on the abdomen in improving constipation in elderly long-term care patients. METHODS: Thirty constipated elderly patients were randomly selected from two nursing homes. They were instructed to use the device once daily for 20 min. Rate of bowel movements, volume and consistency of stool and the use of laxantia were all recorded during a 3-wk baseline period and for 12-wk treatment period. Colonic transit time (CTT) was measured in 13 patients by radiopaque markers during the baseline and at the end of treatment. RESULTS: Bowel movement rate (BM/week) increased from 1.4±0.4 BM/wk during baseline to 3.9±0.8 BM/wk during treatment (P<5.0×10-7). Stool amount that was 'low' in 30 patients during baseline increased in 21 patients at the end of the study period (x2 = 19.048-P= 1.3×10-5). Stool consistency,that was 'hard' in 25 patients and 'soft' in 5 patients during baseline, ameliorated in 23 patients at the end of the study (only 2 patients referred 'hard' stool) (x2 = 21.043-P= 4.0×10-6). The mean baseline CTT measured was 92.3±32.3 h at baseline and decreased to 49.4±31.3 h during the study period (P = 0.000208). No side effects were observed during the study period. CONCLUSION: External mechanical vibration of the abdomen reduced CTT and helped to relieve severe constipation in elderly constipated patients.

Study on the characteristics of intestinal motility of constipation in patients with Parkinson's disease

BACKGROUND Constipation is one of the most important nonmotor symptoms in Parkinson's disease(PD)patients,and constipation of different severities is closely related to the pathogenesis of PD.PD with constipation(PDC)is considered a unique type of constipation,but its mechanism of formation and factors affecting its severity have been less reported.Understanding the gastrointestinal motility characteristics and constipation classification of PDC patients is essential to guide the treatment of PDC.In this study,the colonic transit test and high-resolution anorectal manometry were used to identify the intestinal motility of PDC to provide a basis for the treatment of PDC.AIM To investigate the clinical classification of PDC,to clarify its characteristics of colonic motility and rectal anal canal pressure,and to provide a basis for further research on the pathogenesis of PDC.METHODS Twenty PDC patients and 20 patients with functional constipation(FC)who were treated at Xuanwu Hospital of Capital Medical University from August 6,2018 to December 2,2019 were included.A colonic transit test and high-resolution anorectal manometry were performed to compare the differences in colonic transit time,rectal anal canal pressure,and constipation classification between the two groups.RESULTS There were no statistically significant differences in sex,age,body mass index,or duration of constipation between the two groups.It was found that more patients in the PDC group exhibited difficulty in defecating than in the FC group,and the difference was statistically significant.The rectal resting pressure,anal sphincter resting pressure,intrarectal pressure,and anal relaxation rate in the PDC group were significantly lower than those in the FC group.The proportion of paradoxical contractions in the PDC group was significantly higher than that in the FC group.There was a statistically significant difference in the type composition ratio of defecatory disorders between the two groups(P<0.05).The left colonic transit time,rectosigmoid colonic transit time(RSCTT),and total colonic transit time were prolonged in PDC and FC patients compared to normal values.The patients with FC had a significantly longer right colonic transit time and a significantly shorter RSCTT than patients with PDC(P<0.05).Mixed constipation predominated in PDC patients and FC patients,and no significant difference was observed.CONCLUSION Patients with PDC and FC have severe functional dysmotility of the colon and rectum,but there are certain differences in segmental colonic transit time and rectal anal canal pressure between the two groups.

目的 探讨中医内治法治疗结肠慢传输型便秘(CSTC)的用药规律。方法 检索中国知网(CNKI)、万方(Wanfang)、维普(VIP)、中国生物医学文献服务系统(SinoMed)中以中医内治法治疗CSTC的临床研究文献,筛选符合标准的文献,使用WPS表格建立数据库,运用SPSS Modeler 18.0、SPSS Statistics 26.0与Origin 2024等软件对提取的数据进行分析。结果 本研究共纳入处方83首,涉及中药120味,得到高频中药(使用频次≥14)24味,依次为当归、白术等;中药功效分类以补虚药、理气药为主;药物四气以温、寒为主,五味以甘、苦为主,归经以脾经、胃经为主。高频中药关联规则分析共得到15种核心药物组合;Pearson相关性分析得到10种药对;因子分析提取得到10个公因子;系统聚类分析得到5类组方。结论 中医内治法治疗CSTC多以润肠通便为主,补气、养血并举,辨证配伍补虚、理气等药物。

结肠传输试验在慢传输型便秘诊断中的应用

目的探讨结肠传输试验在慢传输型便秘（slow transit constipation,STC）诊治中的价值和意义。方法收集2007年9月至2013年5月于我院行结肠传输试验的414例受检者的资料,包括男性87例,女性327例,年龄13~82岁,平均45.9岁,临床表现大便次数减少、便意减弱,可伴随有大便干结、排便费力,部分患者需要手助排便,病程3~37年,平均10.7年,病情符合罗马Ⅲ诊断标准。受检者口服含有20粒不透光标记物的胶囊,观察其在服药后24、48、72 h腹部立位片中标记物的分布情况,比较各组标记物数量的差异。结果 414例按72 h残留于大肠的标记物的数量进行分组,〉20%为阳性组,≤20%为阴性组,阳性组197例,阴性组217例。两组在各时间点差异具有统计学意义（P〈0.05）。结论结肠传输试验可以如实地反映在人群结肠传输功能方面确实存在的不同程度的异常,结肠传输试验宜反复、多次检查,使结果更为准确。
