Review
BACKGROUND
Numerous recent studies have explored the association between metabolic dysfunction-associated steatotic liver disease (MASLD) and the risk of various extrahepatic cancers. However, the conclusions were inconclusive. The aim of this study was to clarify this relationship by conducting a robust meta-analysis.
METHODS
Systematic searches were conducted on PubMed, Embase and Web of Science databases to identify relevant cohort studies published prior to February 2024. Hazard ratios (HRs) and their corresponding 95% confidence intervals (95% CIs) were combined using a random-effects model in this meta-analysis.
RESULTS
Eighteen cohort studies (approximately 16.7 million participants) were finally included in this meta-analysis. MASLD was linked to a higher risk of extrahepatic cancers, such as gastric (n = 10, HR = 1.47, 95% CI: 1.07-2.01), colorectal (n = 13, HR = 1.33, 95% CI: 1.16-1.53), pancreatic (n = 8, HR = 1.41, 95% CI: 1.11-1.79), biliary tract (n = 5, HR = 1.27, 95% CI: 1.18-1.37), thyroid (n = 6, HR = 1.46, 95% CI: 1.02-2.09), urinary system (n = 10, HR = 1.45, 95% CI: 1.25-1.69), breast (n = 11, HR = 1.17, 95% CI: 1.08-1.26) and female genital organ cancers (n = 10, HR = 1.36, 95% CI: 1.11-1.66). However, there was no statistically significant association between MASLD and the risk of head and neck (n = 6, HR = 1.03, 95% CI: 99-1.07), oesophageal (n = 9, HR = 1.26, 95% CI: 0.86-1.86), lung (n = 9, HR = 1.01, 95% CI: 0.92-1.10), prostate (n = 9, HR = 1.06, 95% CI: 0.94-1.19) or small intestine cancer (n = 2, HR = 1.75, 95% CI: 1.00-3.06).
CONCLUSIONS
This latest large-scale meta-analysis indicated that MASLD was associated with an increased risk of various extrahepatic cancers, such as gastric, colorectal, pancreatic, biliary duct, thyroid, urinary system, breast, skin and female genital cancers. Further research is needed to investigate the mechanisms underlying these associations.

Meta-Analysis
OBJECTIVE
The effect of a pre-operative biliary stent on complications after pancreaticoduodenectomy (PD) remains controversial.
MATERIALS AND METHOD
We conducted a meta-analysis according to the preferred reporting items for systematic reviews and meta-analyses guidelines, and PubMed, Web of Science Knowledge, and Ovid's databases were searched by the end of February 2023. 35 retrospective studies and 2 randomized controlled trials with a total of 12641 patients were included.
RESULTS
The overall complication rate of the pre-operative biliary drainage (PBD) group was significantly higher than the no-PBD group (odds ratio [OR] 1.46, 95% confidence interval [CI] 1.22-1.74; p < 0.0001), the incidence of post-operative delayed gastric emptying was increased in patients with PBD compared those with early surgery (OR 1.21, 95% CI: 1.02-1.43; p = 0.03), and there was a significant increase in post-operative wound infections in patients receiving PBD with an OR of 2.2 (95% CI: 1.76-2.76; p < 0.00001).
CONCLUSIONS
PBD has no beneficial effect on post-operative outcomes. The increase in post-operative overall complications and wound infections urges the exact indications for PBD and against routine pre-operative biliary decompression, especially for patients with total bilirubin < 250 umol/L waiting for PD.

Meta-Analysis
Endoscopic Retrograde Cholangiopancreatography (ERCP) is the primary therapeutic procedure for pancreaticobiliary disorders, and studies highlighted the impact of papilla anatomy on its efficacy and safety. Our objective was to quantify the influence of papilla morphology on ERCP outcomes. We systematically searched three medical databases in September 2022, focusing on studies detailing the cannulation process or the rate of adverse events in the context of papilla morphology. The Haraldsson classification served as the primary system for papilla morphology, and a pooled event rate with a 95% confidence interval was calculated as the effect size measure. Out of 17 eligible studies, 14 were included in the quantitative synthesis. In studies using the Haraldsson classification, the rate of difficult cannulation was the lowest in type I papilla (26%), while the highest one was observed in the case of type IV papilla (41%). For post-ERCP pancreatitis, the event rate was the highest in type II papilla (11%) and the lowest in type I and III papilla (6-6%). No significant difference was observed in the cannulation failure and post-ERCP bleeding event rates between the papilla types. In conclusion, certain papilla morphologies are associated with a higher rate of difficult cannulation and post-ERCP pancreatitis.

Meta-Analysis
BACKGROUND AND AIMS
The current standard of practice is to use a duodenoscope for the evaluation of the major duodenal papilla (MDP). Recently, cap-assisted endoscopy (CAE), which uses a transparent cap at the tip of a standard front-viewing endoscope, has emerged as an alternative.
METHODS
A systematic literature search was performed in several databases from inception to January 2023 to identify studies evaluating the efficacy of CAE for the evaluation of the MDP.
RESULTS
Nine studies including 806 patients met our inclusion criteria. The pooled rate of technical success for CAE was 93.2% (95% confidence interval, 85.6-96.9; I = 84.6%). A subgroup analysis comparing CAE with a standard endoscope showed higher odds for the evaluation of the MDP with CAE (but not a duodenoscope, which was better than CAE) with an odds ratio of 57.294 (95% confidence interval, 17.767-184.755; I = 45.303%).
CONCLUSIONS
CAE offers a significant advantage with high rates of complete MDP evaluation compared with standard forward-viewing endoscopy. However, CAE is associated with lower rates of success when compared with side-viewing endoscopes.

Adjuvant Radiofrequency Ablation Along With Stenting Versus Stenting Alone for Biliary Tree Drainage in Patients With Malignant Biliary Strictures: A Systemic Review and Meta-analysis.
OBJECTIVE
This metanalysis aims to assess the efficacy and safety of biliary stenting along with radiofrequency ablation compared with stents alone to treat malignant biliary obstruction (MBO) due to extrahepatic biliary strictures secondary to cholangiocarcinoma, pancreatic cancer, and metastatic cancer.
METHODS
A systemic search of major databases through April 2022 was done. All original studies were included comparing radiofrequency ablation with stenting versus stenting alone for treating malignant biliary strictures. The primary outcomes of interest were the difference in the mean stent patency and overall survival (OS) days between the 2 groups. The secondary outcome was to compare the adverse events of the 2 groups. The mean difference in the stent patency and OS days was pooled by using a random-effect model. We calculated the odds ratio to compare the adverse events between the 2 groups.
RESULTS
A total of 13 studies with 1339 patients were identified. The pooled weighted mean difference in stent patency was 43.50 days (95% CI, 25.60-61.41), favoring the RFA plus stenting. Moreover, the pooled weighted mean difference in OS was 90.53 days (95% CI, 49.00-132.07), showing improved survival in the RFA group. Our analysis showed no statistically significant difference in adverse events between the 2 groups OR 1.13 (95% CI, 0.90-1.42).
CONCLUSION
Our analysis showed that RFA, along with stent, is safe and is associated with improved stent patency and overall patient survival in malignant biliary strictures. More robust prospective studies should assess this association further.
