Meta-Analysis Review
PURPOSE
To investigate the outcome of laparoscopic repair of duodenal atresia (LRDA) in relation to different approaches with regard to suture material and anastomosis technique. To identify evidence for the safety and efficacy of LRDA compared with the conventional open repair.
METHODS
Systematic search was performed for all studies on LRDA, excluding case reports, and all comparative studies between LRDA and open repair. Chi-square was used to assess associations between complications or conversions rates and different LRDA approaches (suture material, suturing technique). Meta-analysis was employed to compare LRDA and open repair.
RESULTS
The complications and conversions rates of LRDA were not affected by the different suture materials (Silk, Vicryl, PDS; p = 0.51) or suturing technique (interrupted, continuous; p = 0.46). The meta-analysis did not show significant differences between LRDA and open repair in overall complications rate (p = 0.88), time to feeds (p = 0.12) and hospitalization time (p = 0.28), although it revealed longer operative time with LRDA (p < 0.0001).
CONCLUSIONS
LRDA shows comparable safety and efficacy with the open repair, although it is associated with significantly longer operative time. There is no evidence that the type of the suture material or anastomotic technique affects the outcome of LRDA.

Review
The role of cold snare polypectomy (CSP) in curative resection of non-ampullary sporadic duodenal adenomas (NASDA) is debated. We conducted a systematic review and meta-analysis to investigate the efficacy and safety of CSP for NASDA. In this systematic review and meta-analysis, we identified published series of patients with CSP for NASDA by searching PubMed and Google Scholar, which resulted in six papers (205 lesions). The main outcome was the rate of local remission after repeated CSP, the secondary outcomes were rates of local remission at first control and rates for delayed bleeding and immediate perforations. We computed the weighted summary proportions under the fixed and random effects model. The pooled proportion of local remission after repeated CSP was 88% (95% confidence interval [CI] 57%-100%). The pooled proportion of local remission at first control was 81% (95% CI 55%-98%), the pooled proportion of delayed bleeding was 1% (95% CI 0%-4%) and the pooled proportion of immediate perforation was 0% (95% CI 0%-2%). Our meta-analysis suggests that CSP should be considered as the first-line therapy for NASDA.

Meta-Analysis Review
BACKGROUND & AIMS
This study explored the link between duodenal eosinophils and mast cells in patients with functional dyspepsia (FD).
METHODS
MEDLINE (PubMed) and Embase electronic databases were searched until June 2021 for case-control studies reporting duodenal eosinophils and mast cells in FD. Pooled standardized mean difference (SMD), odds ratio, and 95% CIs of duodenal eosinophils and mast cells in FD patients and controls were calculated, using a random-effects model.
RESULTS
Twenty-two case-control studies with 1108 FD patients and 893 controls were identified. Duodenal eosinophils (SMD, 1.29; 95% CI, 0.85-1.73; P = .0001) and mast cells (SMD, 2.11; 95% CI, 1.14-3.07; P = .0001) were increased in FD patients compared with controls. Substantial heterogeneity was found (I = 93.61, P = .0001; and I = 96.69, P = .0001, respectively) and visual inspection of funnel plots confirmed publication bias. Degranulation of duodenal eosinophils was significantly higher in FD patients compared with controls (odds ratio, 3.78; 95% CI, 6.76-4.48; P = .0001), without statistically significant heterogeneity. We conducted a sensitivity analysis for duodenal eosinophils, by including only high-quality studies, and the results remained unchanged (SMD, 1.73; 95% CI, 1.06-2.40; P = .0001), with substantial heterogeneity. Postinfectious FD patients had increased duodenal eosinophils compared with controls (SMD, 3.91; 95% CI, 1.32-6.51; P = .001) and FD patients without any history of infection (SMD, 1.42; 95% CI, 0.88-1.96; P = .001). Helicobacter pylori-negative FD patients had significantly higher duodenal eosinophils compared with controls (SMD, 3.98; 95% CI, 2.13-5.84; P = .0001), with substantial heterogeneity. No significant difference in duodenal eosinophils was seen according to FD subtypes.
CONCLUSIONS
This meta-analysis suggests a link between duodenal microinflammation and FD. However, the quality of evidence is very low, largely owing to the unexplained heterogeneity and serious risk of publication bias in all comparative analyses. Thus, causality remains uncertain and further studies are required.

Meta-Analysis Review
OBJECTIVE
Sphincter of Oddi dysfunction (SOD) has been used to describe patients with RUQ abdominal pain without an etiology. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of ES (endoscopic sphincterotomy) for SOD.
METHODS
The study methodology follows the PRISMA guidelines. A comprehensive search was conducted using MEDLINE and EMBASE databases for RCTs with ES in patients with SOD. The primary outcome assessed was the improvement of abdominal pain after ES/sham. A random effects model was used to calculate pooled estimates for each outcome of interest.
RESULTS
Of the initial 55 studies, 23 were screened and thoroughly reviewed. The final analysis included 3 studies. 340 patients (89.7% women) with SOD were included. All patients had a cholecystectomy. Most included patients had SOD type II and III. The pooled rate of technical success of ERCP was 100%. The average clinical success rate was 50%. The pooled cumulative rate of overall AEs related to all ERCP procedures was 14.6%. In the sensitivity analysis, only one study significantly affected the outcome or the heterogeneity.
CONCLUSION
ES appears no better than placebo in patients with SOD type III. Sphincterotomy could be considered in patients with SOD type II and elevated SO basal pressure.

Meta-Analysis Review
() is proved to be the main pathogenic agent of various diseases, including chronic gastritis, gastric ulcer, duodenal ulcer, and gastric cancer. In addition, chronic cholecystitis and cholelithiasis are common worldwide, which are supposed to increase the total mortality of patients. Epidemiologic evidence on the relationship between infection of the gallbladder and chronic cholecystitis/cholelithiasis still remains unclear. We conducted a systematic review and meta-analysis of overall studies to investigate the relationship between infection of the gallbladder and chronic cholecystitis/cholelithiasis. Two researchers searched PubMed, Embase, and Cochrane Library databases to obtain all related and eligible studies published before July 2020. The pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated by the random-effects model. Subgroup analysis, heterogeneity, publication bias, and sensitivity analysis were also conducted. Twenty studies were included in the meta-analysis, involving 1735 participants and 1197 patients with chronic cholecystitis/cholelithiasis. species infection of the gallbladder was positively correlated with increased risk of chronic cholecystitis and cholelithiasis, especially (OR = 3.05; 95% CI, 1.81-5.14; = 23.5%). Besides, country-based subgroup analysis also showed a positive correlation between the gallbladder positivity and chronic cholecystitis/cholelithiasis risk. For Asian and non-Asian country studies, the ORs were 4.30 (95% CI, 1.76-10.50; = 37.4%) and 2.13 (95% CI, 1.23-3.70; = 0.0%), respectively. The association was more obvious using the bile sample and urease gene primer. In conclusion, this meta-analysis provided evidence that there is a positive correlation between infection in the gallbladder and increased risk of chronic cholecystitis and cholelithiasis.

Review
OBJECTIVES
Anorexia nervosa (AN) is an eating disorder accompanied by a low body mass index and (self-) restricted food intake. Nutritional limitations can cause complaints of the digestive system, because of a disturbed absorption of food components. The absorption of carbohydrates may be seriously affected and reduced to a minimum. On this basis, a possible connection between AN, and the prevalence of gastrointestinal symptoms due to malabsorption was examined.
METHODS
For the systematic literature research with the aim of a better understanding of the topic the databases PubMed, Web of Science, Cochrane Library, Livivo and Google Scholar were used.
RESULTS
After the manual selection process of 2215 retrieved studies, 89 full texts were read and according to the predetermined eligibility criteria, finally 2 studies on the monosaccharide fructose and disaccharide lactose were included in this review.
CONCLUSION
Malabsorption is often observed in patients with AN. It may contribute to the gastrointestinal complaints reported by patients and hamper body weight regain. Among others, mucosal atrophy and duodenal transporter dysfunction are discussed as main reasons. In the future more studies on carbohydrate malabsorption related to low body weight as observed in AN are warranted and may be conducted rather in an outpatient setting.

Meta-Analysis Review
INTRODUCTION
Effective workup and listing of end-stage renal disease (ESRD) patients for renal transplantation, often with multiple co-morbidities, poses a challenge for transplant teams. Obesity is a common co-morbidity associated with adverse outcomes in ESRD and kidney transplant (KT) recipients. Bariatric and metabolic surgery (BMS) has long been established as a safe and effective treatment for morbid obesity. In this study, the authors aimed to evaluate the strength of evidence for both the efficacy and safety of bariatric surgery in patients with ESRD or kidney transplantation.
METHODS
A literature search was performed using key terms including "transplantation", "kidney", "renal", "obesity", and "bariatric". Databases searched include MEDLINE, EMBASE and Web of Science from inception to date (April 2021). Methodological quality was assessed using the Newcastle-Ottawa tool. Selected articles were then categorised into patients awaiting waiting list acceptance, patients awaiting transplantation, patients undergoing simultaneous BMS + KT and patients undergoing BMS following a previous renal transplant. Summary effects are presented with a level of statistical significance and 95% Confidence Intervals.
RESULTS
A total of 28 articles were selected following the literature search. Fourteen studies on patients awaiting listing (n = 1903), nine on patients on the KT waiting list (n = 196), a single study on simultaneous BMS and KT and ten studies on patients undergoing BMS following KT (n = 198). Mean change in BMI for patients awaiting listing was -11.3 kg/m (95%CI: -15.3 to -7.3, p < 0.001), mean change in BMI for patients listed for KT was -11.2 kg/m 2(95%CI: -12.9 to -9.5, p 0.001) and mean change for patients with prior KT was -11.0 kg/m (95%CI: -7.09 to -14.9, p < 0.001). The combined mortality rate for patients who had undergone both BMS and KT was 4% (n = 15).
DISCUSSION
This review demonstrates BMS is both safe and efficacious in patients with ESRD prior to KT and in those post KT. It would enable difficult-to-list obese recipients the possibility to undergo transplantation and should be considered as part of the work up process.

Review
Ampullary lesions (ALs) can be treated by endoscopic (EA) or surgical ampullectomy (SA) or pancreaticoduodenectomy (PD). However, EA carries significant risk of incomplete resection while surgical interventions can lead to substantial morbidity. We performed a systematic review and meta-analysis for R0, adverse-events (AEs) and recurrence between EA, SA and PD. Electronic databases were searched from 1990 to 2018. Outcomes were calculated as pooled means using fixed and random-effects models and the Freeman-Tukey-Double-Arcsine-Proportion-model. We identified 59 independent studies. The pooled R0 rate was 76.6% (71.8-81.4%, I = 91.38%) for EA, 96.4% (93.6-99.2%, I = 37.8%) for SA and 98.9% (98.0-99.7%, I = 0%) for PD. AEs were 24.7% (19.8-29.6%, I = 86.4%), 28.3% (19.0-37.7%, I = 76.8%) and 44.7% (37.9-51.4%, I = 0%), respectively. Recurrences were registered in 13.0% (10.2-15.6%, I = 91.3%), 9.4% (4.8-14%, I = 57.3%) and 14.2% (9.5-18.9%, I = 0%). Differences between proportions were significant in R0 for EA compared to SA ( = 0.007) and PD ( = 0.022). AEs were statistically different only between EA and PD ( = 0.049) and recurrence showed no significance for EA/SA or EA/PD. Our data indicate an increased rate of complete resection in surgical interventions accompanied with a higher risk of complications. However, studies showed various sources of bias, limited quality of data and a significant heterogeneity, particularly in EA studies.

BACKGROUND
Groove pancreatitis is a focal form of chronic pancreatitis affecting the area of the paraduodenal groove. The aim of this systematic review was to assess the clinical presentation, diagnosis and treatment of patients with groove pancreatitis.
METHODS
Medical literature databases (Embase, Medline via PubMed and Cochrane Central Register of Controlled Trials) were systematically searched for data recorded between 1 January 1990 and 31 August 2022 regarding patient characteristics, diagnosis, surgical treatment and outcomes. The following inclusion criteria were applied: RCTs, observational studies (cohort and case-control studies) and case studies with >3 cases including patients with groove pancreatitis undergoing medical, endoscopic or surgical treatment with available clinical and diagnostic data. Fisher's exact test for binary data and Mann-Whitney U test or Student t-test for continuous data were adopted for statistical analysis.
RESULTS
Of 649 studies, 44 were included, involving reports on 1404 patients with a mean age of 49 years. In 41 of the 44 studies in which patient gender was described, 86 per cent (N = 1023) of patients were male. Information on the risk factors of alcohol and nicotine was available in 37 and 23 studies, respectively. Seventy-nine per cent (N = 886) of patients had a history of excessive alcohol consumption and 83 per cent (N = 595) were smokers. Information on clinical symptoms was available in 37 of the 44 included studies and 78.5 per cent (N = 870) presented with abdominal pain. Some 27 studies comprising 920 groove pancreatitis patients were treatment oriented. Seventy-four per cent (N = 682) of patients were treated conservatively, 26.4 per cent (N = 134) underwent endoscopic treatment and 54.7 per cent (N = 503) required surgery. There was complete relief of symptoms in 35.6 per cent (N = 243) after conservative treatment, 55.2 per cent (N = 74) after endoscopic treatment and 69.6 per cent (N = 350) after surgical treatment. The median follow-up time was 42 months (range, 1-161 months).
CONCLUSION
Groove pancreatitis shows on imaging a typical triad: cystic lesions in the pancreatic duct or duodenal wall, calcifications, and thickenings of the duodenal wall. Surgery appears to be the most effective treatment modality.

Meta-Analysis Review
Duodenal mucosal resurfacing (DMR) is an innovative endoscopic bariatric and metabolic therapy (EBMT) emerging in recent years. It uses the duodenum to achieve better glycemic and weight control. This study aimed to evaluate in a critical and systematic way the metabolic effects of this procedure. Electronic searches were performed evaluating the DMR procedure based on predefined inclusion and exclusion criteria. Changes in measured outcomes were evaluated using random-effects models by computing weighted mean differences (MD) and corresponding 95% CIs between pre-and post-procedure metabolic characteristics. Four studies were selected for qualitative and quantitative analysis. DMR demonstrated beneficial glycemic and hepatic metabolic effects among patients with non-insulin dependent type 2 diabetes (T2D) at 3 and 6 months post-procedure.
