- Background
/Aim: Endoscopic vacuum-assisted closure (EVAC) is a novel technique used to repair esophageal perforation and leaks. Varying data have been reported on the overall success rate of EVAC. We aimed to conduct a metanalysis of the available data on the clinical success rate of EVAC.
Methods
Electronic databases were searched for publications addressing the efficacy of EVAC in esophageal luminal defects. Pooling was conducted using both fixed and random-effects models. The overall clinical success of EVAC therapy was considered the primary outcome, whereas, overall complication rates, need for adjunct therapy, and mortality were considered secondary outcomes.
Results
In total, 366 patients were included in the study. On pooled analysis, the mean age was 66 years with 68.32% of patients being men. Overall pooled clinical success rate of EVAC therapy was 87.95%. Upon subgroup analysis, the pooled clinical success rate of postsurgical anastomotic leak and transmural esophageal perforation were found to be 86.57% and 88.89%, respectively. The all-cause hospital mortality was 14% and 4.2% in patients with esophageal perforation and EVAC, respectively.
Conclusions
This study demonstrates that EVAC therapy has a high overall clinical success rate, with low mortality. EVAC therapy seems to be a promising procedure with excellent outcomes in patients with luminal esophageal defects.

- Background
/Aims: Cold snare polypectomy (CSP) is commonly used for the resection of colorectal polyps ≤10 mm. Data regarding the influence of snare type on CSP effectiveness are conflicting. Hence, this meta-analysis aimed to compare the outcomes and safety of thin- and thick-wire snares for CSP.
Methods
A comprehensive search of the literature published between 2000 and 2021 was performed of various databases for comparative studies evaluating the outcomes of thin- versus thick-wire snares for CSP.
Results
Five studies with data on 1,425 polyps were included in the analysis. The thick-wire snare was comparable to the thin-wire snare with respect to complete histological resection (risk ratio [RR], 1.03; 95% confidence interval [CI], 0.97–1.09), overall bleeding (RR, 0.98; 95% CI, 0.40–2.40), polyp retrieval (RR, 1.01; 95% CI, 0.97–1.04), and involvement of submucosa in the resection specimen (RR, 1.28; 95% CI, 0.72–2.28). There was no publication bias and a small study effect, and the relative effects remained the same in the sensitivity analysis.
Conclusions
CSP using a thin-wire snare has no additional benefit over thick-wire snares in small colorectal polyps. Factors other than snare design may play a role in improving CSP outcomes.

- Background
/Aims: Carbon dioxide is increasingly used in insufflation during colonoscopy in adult patients; however, air insufflation remains the primary practice among pediatric gastroenterologists. This systematic review and meta-analysis aims to evaluate insufflation using CO2 versus air in colonoscopies in pediatric patients.
Methods
Individualized search strategies were performed using MEDLINE, Cochrane Library, EMBASE, and LILACS databases following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Cochrane working methodology. Randomized control trials (RCTs) were selected for the present meta-analysis. Pooled proportions were calculated for outcomes including procedure time and abdominal pain immediately and 24 hours post-procedure.
Results
The initial search yielded 644 records, of which five RCTs with a total of 358 patients (CO2: n=178 versus air: n=180) were included in the final analysis. The procedure time was not different between the CO2 and air insufflation groups (mean difference, 10.84; 95% confidence interval [CI], -2.55 to 24.22; p=0.11). Abdominal pain immediately post-procedure was significantly lower in the CO2 group (risk difference, -0.15; 95% CI; -0.26 to -0.03; p=0.01) while abdominal pain at 24 hours post-procedure was similar (risk difference, -0.05; 95% CI; -0.11 to 0.01; p=0.11).
Conclusions
Based on this systematic review and meta-analysis of RCT data, CO2 insufflation reduced abdominal pain immediately following the procedure, while pain was similar at 24 hours post-procedure. These results suggest that CO2 is a preferred insufflation technique when performing colonoscopy in pediatric patients.

- Background
/Aims: The use of endoscopic submucosal dissection (ESD) for treating undifferentiated-type early gastric cancer is controversial. The objective of this study was to perform a meta-analysis to compare the long-term outcomes of ESD and surgery for undifferentiated-type early gastric cancer.
Methods
The PubMed, Cochrane Library, and EMBASE databases were used to search for relevant studies comparing ESD and surgery for undifferentiated-type early gastric cancer. The methodological quality of the included publications was evaluated using the Risk of Bias Assessment tool for Nonrandomized Studies. The rates of overall survival, recurrence, adverse event, and complete resection were determined. Odds ratios (ORs) and 95% confidence intervals (CIs) were also evaluated.
Results
This meta-analysis enrolled five studies with 429 and 1,236 participants undergoing ESD and surgery, respectively. No significant difference was found in the overall survival rate between the ESD and surgery groups (OR, 2.29; 95% CI, 0.98–5.36; p=0.06). However, ESD was associated with a higher recurrence rate and a lower complete resection rate. The adverse event rate was similar between the two groups.
Conclusions
ESD with meticulous surveillance esophagogastroduodenoscopy may be as effective and safe as surgery in patients with undifferentiated-type early gastric cancer. Further large-scale, randomized, controlled studies from additional regions are required to confirm these findings.

Abstract
PDFPubReaderePub
- Background
/Aims: Cholangiocarcinoma (CCA) is a rare but aggressive disease with a poor survival. Recent trials have shown improved survival with intraductal radiofrequency ablation (RFA) therapy. We performed a systematic review with meta-analysis to determine the survival benefit of endoscopic RFA for unresectable extrahepatic CCA with malignant biliary obstruction (MBO).
Methods
A systematic search from 1970 to 2020 was performed in MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials. gov. We selected eligible studies reporting relative risks, hazard ratios (HRs), or odds ratios, adjusted by controlling for confounding factors of survival rate and stent patency duration, among patients with extrahepatic CCA with MBO treated with RFA with stent insertion or stent insertion only.
Results
A total of eight trials (three randomized and five nonrandomized) with a total of 420 patients were included in the metaanalysis. Pooled overall survival analysis favored RFA treatment with stent insertion (HR, 0.47; 95% confidence interval [CI], 0.34– 0.64; I2=47%; p=0.09); however, no significant difference was found in the duration of stent patency between the groups (HR, 0.79; 95% CI, 0.57–1.09; I2=7%; p=0.36).
Conclusions
RFA therapy with stent insertion may confer a survival benefit compared with stent insertion only in patients with CCA and MBO.
