Methods : Sixty cases of chronic functional constipation were randomly divided into treatment group (30 cases) and control group (30 cases). Cases in the treatment group were exposed to biofeedback for a fiveweeklong treatment course—individual treatment lasted for 3045 minutes and twice per week. Patients in the control group received PEG 4000 10g BID for five weeks. Data from constipation symptom score, colonic transit test, and anorectal manometry were done and compared before and after two kinds of treatments. Results : Biofeedback training and PEG 4000 could restore the stoolfrequency, stool characteristics and accompanying symptoms to normal or mitigation of the majority of patients with chronic functional constipation, with the total effective rates being 667% and 80% (P gt;005), respectively. After biofeedback training and PGE 4000 treatment, the discharge rate of 72hour markers of colonic transit test significantly increased to 75% and 73%, respectively. Additionally, anorectal pressure decreased dramatically after biofeedback training. Conclusion : Biofeedback training would play a positive role in outlet obstruction and slow transit constipation. Thus, it could be an effective firstline treatment of chronic functional constipation.
ObjectiveTo evaluate the functional outcomes and quality of life in patients with surgery for slow transit constipation (STC).MethodsFrom March 2013 to July 2017, 29 patients undergoing total or subtotal colectomy for STC in our department were analyzed prospectively. Their preoperative and postoperative 1-year follow-up details were analyzed. Evacuation function of all patients was assessed by bowel movements, abdominal pain, bloating, straining, laxative, enema use and the Wexner constipation scales. Quality of life was evaluated by the Gastrointestinal Quality of Life Index (GIQLI) and the short-form (SF)-36 survey.ResultsA high number of patients (93.1%, 27/29) in STC stated that surgery received benefits to their health. Compared with that before operation, the number of bowel movements per week during a 1-year follow-up increased significantly (31.6±19.9 vs. 1.21±0.6, P<0.05). Significant trends toward improvement of bloating, straining, laxative and enema use were noted 1-year following surgery (P<0.05). The Wexner constipation scales scores during a 1-year follow-up decreased significantly (5.69±3.4 vs. 20.34±0.6, P<0.05). The GIQLI scores during a 1-year follow-up increased significantly (120.7±20.4 vs. 78.6±17.3, P<0.05). Moreover, results of SF-36 showed significant improvements in 7 spheres (role physical, role emotional, physical pain, vitality, mental health, social function and general health) during a 1-year follow-up compared with those before operation (P<0.05).ConclusionTotal or subtotal colectomy for STC did not only alleviate constipation symptoms dramatically, but also received significant improvements in the patients’ quality of life.
Objective To summarize the short-term efficacy， surgery complications， and relative experiences in the management of severe functional constipation （SFC） under laparoscopy-assisted subtotal colectomy combined modified Duhamel procedure. Methods All the data of 15 patients underwent laparoscopy-assisted subtotal colectomy combined modified Duhamel procedure from March 2010 to August 2011 were collected retrospectively， all the patients were diagnosed as SFC and failed to conservative therapy. The postoperative short-term efficacy， complications of surgery， score of gastrointestinal living condition， and improvement degree of defecation were analyzed. Results All 15 procedures achieved success， the operation time was （247.33±55.10） min， the intraoperative blood loss volume was （107.33±45.59） ml， the incision length was （8.40±2.41） cm， the postoperative out of bed activity time was （2.27±1.28） d，the postoperative passage of gas by anus time was （2.60±1.89） d， the postoperative defecation time was （2.87±2.50） d，the postoperative foods taken per oral time was （3.07±1.16） d， the hospital stay was （12.64±2.37） d. Approximately on day 3-4 after operation， 10 patients presented with postoperative diarrhea but were all under control with antidiarrheals efficiently. One patient presented with incomplete bowel obstruction on day 8 after operation and one patient with stomal leakage complicated with deep infection on day 9 after operation， who both recovered under conservative therapy. The scoreof gastrointestinal living quality on month 1 after operation was significantly higher than that on day 1 before operation （121.80±4.72 versus 90.80±7.24， P=0.000）， and the improvement degree of defecation was （0.81±0.56）%. Conclusions From the limited case informations， the laparoscopy-assisted subtotal colectomy combined modified Duhamel procedure has a certain short-term curative effect in treatment for SFC with the advantages of faster recovery， less bleeding， shorter hospital stay， and fewer complications.
Objective
To explore the effect of triple viable bifidobacterium lactobacillus tablets combined with polyethylene glycol 4000 on elderly patients with chronic constipation.
Methods
This pilot study was conducted at the Center of Gerontology and Geriatrics, West China Hospital. A total of 120 patients with chronic constipation, aged 60 years or older, treated between April 2015 and April 2016 were enrolled, and randomly assigned into group A (polyethylene glycol 4000) and group B (triple viable bifidobacterium lactobacillus tablets combined with polyethylene glycol 4000) with 60 patients in each. All the patients were estimated before and after the treatment with Bristol Stool Form Scale (BSFS), Patient Assessment of Constipation Symptom (PAC-SYM) and Constipation Related Disability (CRDS), and the adverse drug reactions were observed.
Results
In group A, before the treatment, the scores of BSFS, PAC-SYM and CRDS were 1.98±0.77, 37.87±4.12 and 31.03±3.19, respectively; while after the treatment, the scores were 3.87±0.82, 28.55±2.15 and 18.56±1.80, respectively, which were all significantly improved (P<0.05). In group B, before the treatment, the scores of BSFS, PAC-SYM and CRDS were 2.03±0.78, 36.25±4.98 and 30.28±3.56, respectively; while after the treatment, the scores were 4.80±0.75, 19.73±3.42 and 13.80±2.36, respectively, which were all significantly improved (P<0.05). The improvement of constipation in group B was significantly better than that in group A after treatment (P<0.05). There was no adverse drug reaction observed.
Conclusion
Triple viable bifidobacterium lactobacillus tablets combined with polyethylene glycol 4000 may be an effective therapy for elderly patients with chronic constipation.
ObjectiveTo explore the clinical effect of healthy education on functional constipation caused by unhealthy lifestyle, and to analyze the disadvantages affecting the curative effect.
MethodsA total of 167 cases of functional constipation from February 2009 to February 2012 were included. All of the patients were followed up for one year. We collected clinical data of curative effect and influencing factors, determined the clinical value of healthy education, and analyzed the influence of different factors on the curative effect of healthy education.
ResultsThe total curative effect after one-year follow-up was 84.4%. The curative effect in elderly patients was significantly higher than that in middle-aged ones (P<0.05). The curative effect in urban patients was remarkably higher than that in rural ones (P<0.05). And the curative effect of patients with college degree wass much higher than that in patients with education background of primary school or below (P<0.05).
ConclusionHealthy education has important value on releasing and eliminating functional constipation caused by unhealthy lifestyle. And it needs individual education aimed at patients with different age, education degree, and domicile.
ObjectiveTo investigate changes in anal dynamics and anorectal sensory function in patients with irritable bowel syndrome with constipation (IBS-C) and detect its status of basin’s myoelectric pressure. MethodsThirty-six patients with IBS-C (IBS-C group) and 28 healthy volunteers (control group) were collected. The rectal-anal canal pressure and the change of the basin’s myoelectric status were detected by the ZJ-D3 gastrointestinal motility tester and bio-stimulus feedback instrument, respectively. The anal canal resting pressure, rectal resting pressure, anorectal pressure difference, length of anal canal high pressure area, rectal sensation threshold, rectal compliance, and basin’s myoelectric voltage were compared between these two groups. ResultsThere were no significant differences in the rectal resting pressure and anal canal resting pressure between the IBS-C group and the control group (t=–2.312, P=0.851; t=–5.464, P=0.283), but the difference value of anorectal pressure of the IBS-C group was significantly higher than that of the control group (t=4.371, P=0.017), and the length of the anal canal hypertension area in the IBS-C group was significantly longer than that of the control group (t=6.180, P=0.042). The maximal and minimum basin’s myoelectric voltage and frequency of the basin’s myoelectric voltage in the IBS-C group were significantly higher than those in the control group (t=3.386, P=0.031; t=5.763, P=0.042; t=8.410, P<0.001). ConclusionAnorectal dynamics and rectal sensory dysfunction are one of important causes of IBS-C, it might be existed abnormal changes in basin’s myoelectric voltage.
Objective To investigate the current status of constipation during postoperative hospitalization and the factors associated with moderate to severe constipation at discharge in lung cancer patients. Methods Lung cancer patients who underwent surgery in 6 tertiary hospitals in Sichuan Province from November 2017 to January 2020 were enrolled. The MD Anderson Symptom Scale-Lung Cancer Module was used to collect postoperative constipation scores. Unconditional logistic stepwise regression was used to analyze the related influencing factors for moderate to severe constipation on the day of discharge. Results Finally 337 patients were collected. There were 171 males and 166 females, with an average age of 55.0±10.3 years. Constipation scores of lung cancer patients increased from postoperative day 1 to day 3, and showed a decreasing trend from day 3 to day 7. Moderate to severe constipation was present in 68 (20.2%) patients at discharge. The postoperative hospital stay (OR=0.743, P<0.001) and the dose of morphine used during postoperative hospitalization (OR=1.002, P=0.015) were influencing factors for moderate to severe constipation at discharge in lung cancer patients. ConclusionLung cancer patients have the most severe constipation on postoperative day 3. Moderate to severe constipation at discharge is associated with the postoperative hospital stay and the dose of morphine used during postoperative hospitalization.
ObjectiveTo investigate efficacy of total colectomy-ileorectal anastomosis (IRA) and subtotal colectomy-ileosigmoidal anastomosis (ISA) in treatment of patients with slow transit constipation (STC).MethodsThe clinical data of 45 patients with STC underwent operation from January 2008 to January 2015 were analyzed retrospectively. These patients were divided into an IRA group and ISA group according to the operation method, there were 23 cases in the IRA group and 22 cases in the ISA group. The operative time, intraoperative blood loss, postoperative hospitalization, use of antidiarrheal drugs, and complications rate in both groups were compared. All the patients were followed up at the 3th, 6th, 12th, and 24th month after the operation, the defecation frequency, Wexner continence score, Wexner anal incontinence score, gastrointestinal quality of life index score, abdominal pain frequency score, and abdominal distension frequency score in two groups were evaluated.ResultsThere were no significantly statistical differences between the two groups in the operation time, intraoperative blood loss, and postoperative complications rate (P>0.05). In the perioperative period, compared with the IRA group, the ISA group had a shorter postoperative hospitalization and a relatively lower proportion of antidiarrheal drugs, the differences were statistically significant between the two groups (P<0.05). On the postoperative 3th, 6th, and 12th month, the frequency of defecation in the IRA group was significantly higher than that in the ISA group (P<0.05). The Wexner continence score, Wexner anal incontinence score, gastrointestinal quality of life index score, abdominal pain frequency score, and abdominal distension frequency score had no statistical differences between the two groups (P>0.05).ConclusionsISA and IRA are safe and effective in treatment of STC, it might be selected according to patient’s conditions. On premise of strictly grasping indications, ISA has more obvious advantages.
ObjectiveTo systematically evaluate the related factors of constipation in patients with stroke. MethodsCochrane Library, PubMed, Web of Science, Embase, CNKI, VIP, Wanfang and China Biomedical Literature Database were searched by computer, and the retrieval time was set to May 2022. Case-control studies, cohort studies and cross-sectional studies on stroke and constipation were selected. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 13 studies involving 2 834 patients were included. Meta-analysis showed that age [odds ratio (OR) =2.54, 95% confidence interval (CI) (1.36, 3.73), P<0.001], lesion location [OR=1.98, 95%CI (1.27, 3.11), P=0.003], National Institutes of HealthStroke Scale score [OR=0.40, 95%CI (0.10, 0.70), P=0.010], hemiplegia [OR=4.31, 95%CI (2.59, 7.17), P<0.001], dysphagia [OR=2.32, 95%CI (1.27, 4.25), P=0.006], antidepressants [OR=2.33, 95%CI (1.62, 3.34), P<0.001], BI score [OR=?17.08, 95%CI (?33.07, ?1.08), P=0.04], eating pattern [OR=4.18, 95%CI (1.16, 15.09), P=0.030], drinking water volume ≥800 mL [OR=0.30, 95%CI (0.19, 0.46), P<0.001] might be the influencing factors of constipation in patients after stroke. The results of sensitivity analysis showed that age, education level, diabetes, smoking, stroke type, lesion location, diuretic and BI score might be the influencing factors of constipation after stroke (P<0.05). The results of bias analysis suggest that publication bias is less likely. Conclusions There are many risk factors for constipation in patients with stroke. Current evidence shows that age, diabetes, smoking and other 11 factors may be risk factors for stroke constipation, while high education level and drinking water ≥800 mL may be protective factors, and the other influencing factors have not been determined and need further study.
