Percutaneous endoscopic gastrostomy (PEG) and radiologically inserted gastrostomy (RIG) have gained increasing popularity among clinicians and motor neuron disease (MND) patients for maintaining adequate nutritional intake. However, there is no consistent evidence of the efficacy and safety of the two techniques in MND patients. We carried out a systematic review and meta-analysis to examine the technical success rates, complication rates and 30-day mortality of MND patients receiving PEG and RIG. We searched PubMed, EMBASE, the Cochrane Library, Web of Science and Scopus from inception to September 12, 2019 for comparative studies on the efficacy and safety of PEG and RIG in MND patients. The primary outcome was technical success rate and the secondary outcomes were complication rates and 30-day mortality. Seven studies (n = 603) were included. Pooled technical success rates were 90.15% in patients receiving PEG and 96.76% in patients undergoing RIG. There was a statistically significant difference in the technical success rate between RIG and PEG, strongly favoring RIG [(OR = 3.96, 95% CI (1.31to 12.02); P =.02]. Pooled major complication rates were 2.19% in patients receiving PEG and 0.07% in patients undergoing RIG, with no statistical difference (P =.08). Pooled procedure-related 30-day mortality rates were 5.31% in patients receiving PEG and 6.00% in patients undergoing RIG, with no statistically significant difference (P =.75). No publication bias was noted. The present meta-analysis demonstrated that, compared to PEG, RIG has a higher technical success rate and has a comparable mortality outcome and safety profile. • More comprehensive meta-analysis of the safety of RIG versus PEG special in MND patients • RIG had a higher technical success rate compared with PEG in MND patients. • RIG is more appropriate for ALS patients.

Cancer of the digestive system is a common cancer and results in high mortality rates world-wide. miR-27a polymorphism has been associated with an increased risk of digestive system cancers; however, this has not been conclusively shown yet. Therefore, to clarify this, we conducted a comprehensive meta-analysis. PubMed, EMBASE, OVID and Cochrane Library databases were comprehensively searched to retrieve eligible studies published up to May 10, 2020 that referred to digestive cancers. Odds ratios and the corresponding 95 % confidence intervals (CI) were used when calculating the relationship between miR-27a rs895819 polymorphism and susceptibility to digestive cancers. A significant correlation between the miR-27a rs895819 polymorphism and the presence of digestive system cancers was found in four genetic models, which were the homozygote, dominant, recessive, and allele genetic models (GG vs AA: OR = 1.210, 95 %CI = 1.020–1.436, P = 0.029; GG + AG vs AA: OR = 1.092, 95 %CI = 1.024–1.164, P = 0.007; GG vs AG + AA: OR = 1.182, 95 %CI = 1.005–1.390, P = 0.044; G vs A: OR = 1.099, 95 %CI = 1.046–1.154, P < 0.001). Hierarchical analysis by ethnicity suggested that miR-27a rs895819 significantly increased the risk of digestive system cancers in the Asian population, but not in Caucasians. Additionally, rs895819 polymorphism was found to be significantly associated with colorectal cancer and gastric cancer. The miR-27a rs895819 polymorphism may be associated with an increased risk for digestive system cancers. [ABSTRACT FROM AUTHOR]
