Meta-Analysis
BACKGROUND
Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract, in which the pathogenesis is believed to be partly influenced by the gut microbiome. Probiotics can be used to manipulate the microbiome and have therefore been considered as a potential therapy for CD. There is some evidence that probiotics benefit other gastrointestinal conditions, such as irritable bowel syndrome and ulcerative colitis, but their efficacy in CD is unclear. This is the first update of a Cochrane Review previously published in 2008.
OBJECTIVES
To assess the efficacy and safety of probiotics for the induction of remission in CD.
SEARCH METHODS
The following electronic databases were searched: MEDLINE (from inception to 6 July 2020), Embase (from inception to 6 July 2020), the Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane IBD Review Group Specialised Trials Register, World Health Organization (WHO) International Clinical Trials Registry, and ClinicalTrials.gov.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compared probiotics with placebo or any other non-probiotic intervention for the induction of remission in CD were eligible for inclusion.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data and assessed the methodological quality of included studies. The primary outcome was clinical remission. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated for dichotomous outcomes.
MAIN RESULTS
There were two studies that met criteria for inclusion. One study from Germany had 11 adult participants with mild-to-moderate CD, who were treated with a one-week course of corticosteroids and antibiotics (ciprofloxacin 500 mg twice daily and metronidazole 250 mg three times a day), followed by randomised assignment to Lactobacillus rhamnosus strain GG (two billion colony-forming units per day) or corn starch placebo. The other study from the United Kingdom (UK) had 35 adult participants with active CD (CDAI score of 150 to 450) randomised to receive a synbiotic treatment (comprised of freeze-dried Bifidobacterium longum and a commercial product) or placebo. The overall risk of bias was low in one study, whereas the other study had unclear risk of bias in relation to random sequence generation, allocation concealment, and blinding. There was no evidence of a difference between the use of probiotics and placebo for the induction of remission in CD (RR 1.06; 95% CI 0.65 to 1.71; 2 studies, 46 participants) after six months. There was no difference in adverse events between probiotics and placebo (RR 2.55; 95% CI 0.11 to 58.60; 2 studies, 46 participants). The evidence for both outcomes was of very low certainty due to risk of bias and imprecision.
AUTHORS' CONCLUSIONS
The available evidence is very uncertain about the efficacy or safety of probiotics, when compared with placebo, for induction of remission in Crohn's disease. There is a lack of well-designed RCTs in this area and further research is needed.

Meta-Analysis Review
A Low-FODMAP Diet Provides Benefits for Functional Gastrointestinal Symptoms but Not for Improving Stool Consistency and Mucosal Inflammation in IBD: A Systematic Review and Meta-Analysis.
BACKGROUND
A low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols diet (LFD) is claimed to improve functional gastrointestinal symptoms (FGSs). However, the role of LFD in inflammatory bowel disease (IBD) patients with FGSs remains unclear.
OBJECTIVE
To systematically assess the efficacy of LFD in IBD patients with FGSs.
METHODS
Six databases were searched from inception to 1 January 2022. Data were synthesized as the relative risk of symptoms improvement and normal stool consistency, mean difference of Bristol Stool Form Scale (BSFS), Short IBD Questionnaire (SIBDQ), IBS Quality of Life (IBS-QoL), Harvey-Bradshaw index (HBi), Mayo score, and fecal calprotectin (FC). Risk of bias was assessed based on study types. A funnel plot and Egger's test were used to analyze publication bias.
RESULTS
This review screened and included nine eligible studies, including four randomized controlled trials (RCTs) and five before-after studies, involving a total of 446 participants (351 patients with LFD vs. 95 controls). LFD alleviated overall FGSs (RR: 0.47, 95% CI: 0.33-0.66, = 0.0000) and obtained higher SIBDQ scores (MD = 11.24, 95% CI 6.61 to 15.87, = 0.0000) and lower HBi score of Crohn's disease (MD = -1.09, 95% CI -1.77 to -0.42, = 0.002). However, there were no statistically significant differences in normal stool consistency, BSFS, IBS-QoL, Mayo score of ulcerative colitis, and FC. No publication bias was found.
CONCLUSIONS
LFD provides a benefit in FGSs and QoL but not for improving stool consistency and mucosal inflammation in IBD patients. Further well-designed RCTs are needed to develop the optimal LFD strategy for IBD.

Meta-Analysis
BACKGROUND AND AIMS
Patients with inflammatory bowel disease (IBD) have an increased risk of colorectal cancer (CRC). We performed a systematic review and meta-analysis to identify all prognostic factors for advanced colorectal neoplasia (aCRN, high-grade dysplasia, or CRC) in patients with IBD.
METHODS
A systematic literature search was conducted according to the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. Risk of bias was assessed using the Quality in Prognostic Studies tool. Random-effects models were created separately for odds and hazard ratios, different study designs, and univariable or multivariable data. The evidence for all prognostic factors was categorized as "weak", "moderate", or "strong", based on estimate of effect sizes, heterogeneity, and risk of bias.
RESULTS
A total of 164 studies were included, allowing pooled analysis of 31 potential prognostic factors. In the univariable analysis, the evidence for extensive disease was classified as strong while evidence for low-grade dysplasia, strictures, primary sclerosing cholangitis, post-inflammatory polyps, family history of CRC, and ulcerative colitis versus Crohn's disease was considered moderate. Evidence for any dysplasia, colon segment resection, aneuploidy, male sex, and age was classified as weak. In addition, histologic inflammation was identified as a risk factor in multivariable analysis (weak evidence). The evidence for the protective factors colonoscopic surveillance, 5-Aminosalicylic Acid, thiopurines, and smoking was moderate in univariable analysis. Multivariable analysis provided weak evidence for statin use.
CONCLUSIONS
In this systematic review and meta-analysis, we identified 13 risk factors and 5 protective factors for aCRN in IBD patients, based on univariable and/or multivariable pooled analyses. These findings might lay the groundwork for an improved CRC risk stratification-based surveillance in IBD.

Meta-Analysis
PURPOSE
A systematic review and meta-analysis was conducted to synthesize the available data from clinical trials and assess the safety issues of tirzepatide (pancreatitis and gallbladder or biliary disease) in type 2 diabetes (T2D) and obesity.
METHODS
A systematic search was conducted in three electronic databases, namely Embase, PubMed, and the Cochrane Library, up until March 1, 2023, to identify randomized controlled trials (RCTs) comparing tirzepatide to either placebo or active hypoglycemic drugs in individuals with T2D and obesity. Heterogeneity was assessed using the I2 value and Cochran's Q test, and a fixed effects model was employed to estimate the safety profile of tirzepatide. The safety outcomes of interest, including pancreatitis, the composite of gallbladder or biliary diseases, cholecystitis, and cholelithiasis and biliary diseases, were evaluated. (The composite of gallbladder or biliary diseases incorporated cholelithiasis, cholecystitis, other gallbladder disorders, and biliary diseases.).
RESULTS
A total of nine trials with 9871 participants (6828 in the tirzepatide group and 3043 in the control group) that met the pre-specified criteria were included. When compared to all control groups consisting of basal insulin (glargine or degludec), selective GLP1-RA (dulaglutide or semaglutide once weekly), and placebo, an increased risk of pancreatitis was not found to be significantly associated with tirzepatide (RR 1.46, [95% CI] 0.59 to 3.61; I2 = 0.0%, p = 0.436). For gallbladder or biliary disease, the composite of gallbladder or biliary disease was significantly associated with tirzepatide compared with placebo or basal insulin (RR 1.97, [95% CI] 1.14 to 3.42; I2 = 0.0%, p = 0.558), but not with the risk of cholelithiasis, cholecystitis or biliary diseases.
CONCLUSION
Based on the currently available data, tirzepatide appears to be safe regarding the risk of pancreatitis. However, the increased risk of the composite outcome of gallbladder or biliary diseases observed in RCTs warrants further attention from physicians in clinical practice.

BMC Gastroenterology Jun 2022There are limited comparative data for infliximab and vedolizumab in inflammatory bowel disease patients. (Meta-Analysis)
Meta-Analysis
BACKGROUND AND AIMS
There are limited comparative data for infliximab and vedolizumab in inflammatory bowel disease patients.
METHODS
We conducted a systematic review and meta-analysis to compare the efficacy and safety of infliximab and vedolizumab in adult patients with moderate-to-severe Crohn's disease or ulcerative colitis.
RESULTS
We identified six eligible Crohn's disease and seven eligible ulcerative colitis trials that randomised over 1900 participants per disease cohort to infliximab or vedolizumab. In the Crohn's disease and ulcerative colitis cohorts, infliximab yielded better efficacy than vedolizumab for all analysed outcomes (CDAI-70, CDAI-100 responses, and clinical remission for Crohn's disease and clinical response and clinical remission for ulcerative colitis) during the induction phase, with non-overlapping 95% confidence intervals. In the maintenance phase, similar proportions of infliximab- or vedolizumab-treated patients achieved clinical response, clinical remission, or mucosal healing in both Crohn's disease and ulcerative colitis. For the safety outcomes, rates of adverse events, serious adverse events, and discontinuations due to adverse events were similar in infliximab- and vedolizumab-treated patients in both diseases. The infection rate was higher in infliximab for Crohn's disease and higher in vedolizumab when treating patients with ulcerative colitis. There was no difference between the treatments in the proportions of patients who reported serious infections in both indications.
CONCLUSIONS
Indirect comparison of infliximab and vedolizumab trials in adult patients with moderate-to severe Crohn's disease or ulcerative colitis demonstrated that infliximab has better efficacy in the induction phase and comparable efficacy during the maintenance phase and overall safety profile compared to vedolizumab.

Meta-Analysis
BACKGROUND & AIMS
Biopsy-confirmed liver fibrosis is a prognostic factor for patients with nonalcoholic fatty liver disease (NAFLD). We performed a systematic review to quantify the prognostic value of fibrosis stage in patients with NAFLD and the subgroup of patients with nonalcoholic steatohepatitis (NASH) and to assess the evidence that change in fibrosis stage is a surrogate endpoint.
METHODS
We searched the MEDLINE, Embase, Cochrane Library, and trial registry databases through August 2018 for prospective or retrospective cohort studies of liver-related clinical events and outcomes in adults with NAFLD or NASH. We collected data on mortality (all cause and liver related) and morbidity (cirrhosis, liver cancer, and all liver-related events) by stage of fibrosis, determined by biopsy, for patients with NAFLD or NASH. Using fibrosis stage 0 as a reference population, we calculated fibrosis stage-specific relative risk (RR) and 95% confidence interval (CI) values for mortality and morbidities. We performed fixed-effect and random-effect model meta-analyses. Metaregression was used to examine associations among study design (prospective vs retrospective cohort), overall risk of bias (medium or high), and mean duration of follow-up (in years).
RESULTS
Our meta-analysis included 13 studies, comprising 4428 patients with NAFLD; 2875 of these were reported to have NASH. Compared with no fibrosis (stage 0), unadjusted risk increased with increasing stage of fibrosis (stage 0 vs 4): all-cause mortality RR, 3.42 (95% CI, 2.63-4.46); liver-related mortality RR, 11.13 (95% CI, 4.15-29.84); liver transplant RR, 5.42 (95% CI, 1.05-27.89); and liver-related events RR, 12.78 (95% CI, 6.85-23.85). The magnitude of RR did not differ significantly after adjustment for confounders, including age or sex in the subgroup of NAFLD patients with NASH. Three studies examined the effects of increasing fibrosis on quality of life had inconsistent findings.
CONCLUSIONS
In a systematic review and meta-analysis, we found biopsy-confirmed fibrosis to be associated with risk of mortality and liver-related morbidity in patients with NAFLD, with and without adjustment for confounding factors and in patients with reported NASH. Further studies are needed to assess the association between fibrosis stage and patient quality of life and establish that change in liver fibrosis stage is a valid endpoint for use in clinical trials.

Meta-Analysis
BACKGROUND & AIMS
Although the association between inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC) is well recognized, uncertainties remain about the magnitude of this problem. We conducted a systematic review and meta-analysis assessing prevalence of PSC in IBD to investigate whether type of IBD, how presence of PSC was defined, sex, disease extent or location, time period, or geographic location influenced prevalence.
METHODS
Medline, Embase, and Embase Classic were searched (from inception to April 10, 2021) to identify observational studies recruiting ≥50 adult patients with IBD and reporting prevalence of PSC. Data were extracted, and pooled prevalence, odds ratios (ORs), and 95% confidence intervals (CIs) calculated.
RESULTS
Of 1204 citations, 64 studies were eligible, containing 776,700 patients. Overall, pooled prevalence of PSC in IBD was 2.16%; it was highest in South America and lowest in Southeast Asia. Pooled prevalences in patients with ulcerative colitis (UC), Crohn's disease (CD), and IBD-unclassified were 2.47%, 0.96%, and 5.01%, respectively. Pooled prevalence was significantly higher in UC versus CD (OR 1.69, 95% CI 1.24-2.29). In subgroup analyses according to method used to define presence of PSC, the highest prevalence was 2.88% in studies performing both liver biochemistry and endoscopic retrograde/magnetic resonance cholangiopancreatography and the lowest was 1.79% in studies using a clinical diagnosis. Prevalence was generally higher in men, patients with more extensive, compared with left-side, UC or ileocolonic or colonic, compared with ileal, CD.
CONCLUSIONS
Our findings provide the first pooled estimates of the burden of PSC in IBD, as well as potential risk factors, which may be important in establishing a prompt diagnosis and initiating appropriate surveillance for relevant gastrointestinal malignancies.

Meta-Analysis
OBJECTIVE
The aim of this study was to appraise the prevalence of gastroesophageal reflux disease (GERD), esophagitis, and Barrett's esophagus (BE) after sleeve gastrectomy (SG) through a systematic review and meta-analysis.
BACKGROUND
The precise prevalence of new-onset or worsening GERD after SG is controversial. Subsequent esophagitis and BE can be a serious unintended sequalae. Their postoperative prevalence remains unclear.
METHODS
A systematic literature search was performed to identify studies evaluating postoperative outcomes in primary SG for morbid obesity. The primary outcome was prevalence of GERD, esophagitis, and BE after SG. Meta-analysis was performed to calculate combined prevalence.
RESULTS
A total of 46 studies totaling 10,718 patients were included. Meta-analysis found that the increase of postoperative GERD after sleeve (POGAS) was 19% and de novo reflux was 23%. The long-term prevalence of esophagitis was 28% and BE was 8%. Four percent of all patients required conversion to RYGB for severe reflux.
CONCLUSIONS
The postoperative prevalence of GERD, esophagitis, and BE following SG is significant. Symptoms do not always correlate with the presence of pathology. As the surgical uptake of SG continues to increase, there is a need to ensure that surgical decision-making and the consent process for this procedure consider these long-term complications while also ensuring their postoperative surveillance through endoscopic and physiological approaches. The long-term outcomes of this commonly performed bariatric procedure should be considered alongside its weight loss and metabolic effects.

(Meta-Analysis)
Meta-Analysis
OBJECTIVE
To assess the impact of type of surgery for colorectal endometriosis-rectal shaving or discoid resection or segmental colorectal resection-on complications and surgical outcomes.
DATA SOURCES
We performed a systematic review of all English- and French-language full-text articles addressing the surgical management of colorectal endometriosis, and compared the postoperative complications according to surgical technique by meta-analysis. The PubMed, Clinical Trials.gov, Cochrane Library, and Web of Science databases were searched for relevant studies published before March 27, 2020. The search strategy used the following Medical Subject Headings terms: ("bowel endometriosis" or "colorectal endometriosis") AND ("surgery for endometriosis" or "conservative management" or "radical management" or "colorectal resection" or "shaving" or "full thickness resection" or "disc excision") AND ("treatment", "outcomes", "long term results" and "complications").
METHODS OF STUDY SELECTION
Two authors conducted the literature search and independently screened abstracts for inclusion, with resolution of any difference by 3 other authors. Studies were included if data on surgical management (shaving, disc excision, and/or segmental resection) were provided and if postoperative outcomes were detailed with at least the number of complications. The risk of bias was assessed according to the Cochrane recommendations.
TABULATION, INTEGRATION, AND RESULTS
Of the 168 full-text articles assessed for eligibility, 60 were included in the qualitative synthesis. Seventeen of these were included in the meta-analysis on rectovaginal fistula, 10 on anastomotic leakage, 5 on anastomotic stenosis, and 9 on voiding dysfunction <30 days. The mean complication rate according to shaving, disc excision, and segmental resection were 2.2%, 9.7%, and 9.9%, respectively. Rectal shaving was less associated with rectovaginal fistula than disc excision (odds ratio [OR] = 0.19; 95% confidence interval [CI], 0.10-0.36; p <.001; I = 33%) and segmental colorectal resection (OR = 0.26; 95% CI, 0.15-0.44; p <.001; I = 0%). No difference was found in the occurrence of rectovaginal fistula between disc excision and segmental colorectal resection (OR = 1.07; 95% CI, 0.70-1.63; p = .76; I = 0%). Rectal shaving was less associated with leakage than disc excision (OR = 0.22; 95% CI, 0.06-0.73; p = .01; I = 86%). No difference was found in the occurrence of leakage between rectal shaving and segmental colorectal resection (OR = 0.32; 95% CI, 0.10-1.01; p = .05; I = 71%) or between disc excision and segmental colorectal resection (OR = 0.32; 95% CI, 0.30-1.58; p = .38; I = 0%). Disc excision was less associated with anastomotic stenosis than segmental resection (OR = 0.15; 95% CI, 0.05-0.48; p = .001; I = 59%). Disc excision was associated with more voiding dysfunction <30 days than rectal shaving (OR = 12.9; 95% CI, 1.40-119.34; p = .02; I = 0%). No difference was found in the occurrence of voiding dysfunction <30 days between segmental resection and rectal shaving (OR = 3.05; 95% CI, 0.55-16.87; p = .20; I = 0%) or between segmental colorectal and discoid resections (OR = 0.99; 95% CI, 0.54-1.85; p = .99; I = 71%).
CONCLUSION
Colorectal surgery for endometriosis exposes patients to a risk of severe complications such as rectovaginal fistula, anastomotic leakage, anastomotic stenosis, and voiding dysfunction. Rectal shaving seems to be less associated with postoperative complications than disc excision and segmental colorectal resection. However, this technique is not suitable for all patients with large bowel infiltration. Compared with segmental colorectal resection, disc excision has several advantages, including shorter operating time, shorter hospital stay, and lower risk of postoperative bowel stenosis.

Meta-Analysis
BACKGROUND & AIMS
Many studies have assessed risk factors of irritable bowel syndrome (IBS) and other abdominal pain-related disorders of gut-brain interaction (AP-DGBI); however, the role of these factors is unclear due to heterogeneous study designs. The aim of this systematic review was to extensively evaluate the literature and determine clinical risk and protective factors for the presence and persistence of AP-DGBI in children and adults.
METHODS
A PubMed search identified studies investigating potential risk and protective factors for AP-DGBI in adults and children. Inclusion criteria included fully published studies with a control group; exclusion criteria included poor-quality studies (using a validated scale). For each factor, the proportion of studies that found the factor to be a risk factor, protective factor, or neither was summarized. The number of studies, diagnostic criteria, number of subjects, and average study quality rating provided further context. Whenever possible, a meta-analysis generated pooled odds ratios or mean difference.
RESULTS
The systematic review included 348 studies. Female sex, gastroenteritis, abuse, stress, psychological disorders, somatic symptoms, and poor sleep were consistent risk factors for developing AP-DGBI in adults and children. In adults, additional risk factors included obesity, smoking, and increased use of medical resources. Protective AP-DGBI factors in adults included social support and optimism; no studies for protective factors were found for children.
CONCLUSIONS
There are multiple risk factors for AP-DGBI in adults and children. These include female sex, gastroenteritis, abuse, stress, poor sleep, obesity, psychological disorders, and somatic symptoms. Additional studies are needed in children, on protective factors, and on factors associated with persistence of AP-DGBI.
