BACKGROUND: There currently exists no substantial evidence reporting the efficacy of peritoneal irrigation in reducing the incidence of postoperative intra-abdominal abscess in pediatric patients. The purpose of our study was to perform a meta-analysis to compare rates of intra-abdominal abscess after appendectomy between irrigation and suction alone groups. METHODS: We identified studies by a systematic search in EMBASE, PubMed, Web of Science, and the Cochrane Library to recognize randomized controlled trials and case control studies from the 1950 to May 2019. We limited the English language studies. We checked the reference list of studies to recognize other potentially qualified trials. We analyzed the merged data with use of the Review Manager 5.3. RESULTS: We identified 6 eligible papers enrolling a total of 1633 participants. We found no significant difference in the incidence of postoperative intraabdominal abscess, wound infection, and the length of hospitalization between 2 group, but duration of surgery is longer in irrigation group (MD = 6.76, 95% CI = 4.64 to 8.87, P < .001; heterogeneity, I = 25%, P = .26). CONCLUSION: Our meta-analysis did not provide strong evidence allowing definite conclusions to be drawn, but suggested that peritoneal irrigation during appendectomy did not decrease the incidence of postoperative IAA. This meta-analysis also indicated the need for more high-quality trials to identify methods to decrease the incidence of postoperative IAA in pediatric perforated appendicitis patients.Trial registration number Standardization of endoscopic treatment of acute abdomen in children: 14RCGFSY00150.

BACKGROUND: Previous studies have neglected to report the specific action of different probiotic genera in preterm infants. To evaluate the efficacy and safety of specific probiotic genera, we performed a network meta-analysis (NMA) to identify the best prevention strategy for necrotizing enterocolitis in preterm infants. METHODS: MEDLINE, PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials had been searched for randomized control trials reporting the probiotics strategy for premature infants. RESULTS: We identified 34 eligible studies of 9161 participants. The intervention in the observation group was to add probiotics for feeding: Lactobacilli in 6 studies; Bifidobacterium in 8 studies; Bacillus in 1 study; Saccharomyces in 4 studies and probiotic mixture in 15 studies. This NMA showed a significant advantage of probiotic mixture and Bifidobacterium to prevent the incidence of necrotizing enterocolitis in preterm infants. A probiotic mixture showed effectiveness in reducing mortality in preterm infants. CONCLUSION: The recent literature has reported a total of 5 probiotic strategies, including Bacillus, Bifidobacterium, Lactobacillus, Saccharomyces, and probiotic mixture. Our thorough review and NMA provided a piece of available evidence to choose optimal probiotics prophylactic strategy for premature infants. The results indicated that probiotic mixture and Bifidobacterium showed a stronger advantage to use in preterm infants; the other probiotic genera failed to show an obvious effect to reduce the incidence of NEC, sepsis and all-cause death. More trials need to be performed to determine the optimal probiotic treatment strategy to prevent preterm related complications.

PURPOSE: We aimed to compare probiotics with placebo for necrotizing enterocolitis in preterm infants and to evaluate the safety and effect and strict effect of specific probiotic genera. METHODS: Data recorded until January 2019 were searched, and relevant academic articles from PubMed, MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were selected by two independent reviewers. Two reviewers independently included randomized controlled trials that compared probiotics and placebo in preterm infants. The outcomes included more than one of the following outcomes: incidence of necrotizing enterocolitis, necrotizing enterocolitis-related mortality, incidence of sepsis, and all-cause mortality. Two reviewers independently extracted data and assessed the risk of bias and quality of evidence. RESULTS: We identified 34 eligible studies of 9161 participants. This meta-analysis showed an overall advantage of probiotics to prevent the incidence of necrotizing enterocolitis (3.54%) and gut-associated sepsis (15.59%), and decrease mortality (5.23%) in preterm infants. A probiotic mixture showed a huge advantage and vitality in preventing necrotizing enterocolitis (2.48%) and gut-associated sepsis (18.39%), and in reducing mortality (5.57%) in preterm infants. CONCLUSION: The probiotic mixture showed advantages over the single strains to decrease the incidences of necrotizing enterocolitis and gut-associated sepsis, and mortality in preterm infants.

OBJECTIVE: To analyze the clinical results of transanal endorectal pull-through (TERPT) and transabdominal approach (TAB) in the treatment of Hirschsprung disease. METHODS: We searched all publications in the PubMed, MEDLINE, EMBASE, and Cochrane library databases between January 2003 and November 2018. The study included randomized controlled trials (RCTs) and observational clinical studies (OCSs), to compare the surgery duration, length of postoperative hospital stay, incidence of postoperative incontinence/soiling, constipation, and enterocolitis between the TERPT and TAB groups. Mantel-Haenszel method was used for continuous variables, the combined odds ratios (ORs) and 95% confidence intervals (CIs) for dichotomous variables were used. RESULTS: In the 87 studies, we include 1 case of RCTs and 9 cases of OCSs. Including 392 cases of TERPT and 332 cases of TAB groups. TERPT has a short postoperative hospitalization [mean difference (MD) = -6.74 day; 95% CIs; -13.26 to -0.23; P = .04], and a low incidence of postoperative incontinence (ORs = 0.54; 95% CIs, 0.35-0.83; P = .006) and constipation (ORs = 0.50; 95% CIs, 0.28-0.90; P = .02). There was no difference in duration of surgery (MD = -30.59 min; 95% CIs, -98.01-36.83; P = .37) and incidence of postoperative enterocolitis (ORs = 0.78; 95% CIs, 0.53-1.17; P = .23). CONCLUSION: TERPT is superior to TAB in terms of hospitalization time, postoperative incontinence, and constipation. However, there are still a large number of RCTs to verify, and more trials are expected to be testified in the future.

Aim: We aimed to compare conservative treatment with surgery for uncomplicated pediatric appendicitis to estimate effectiveness and safety. Methods: Data recorded until September 2018 were searched, and relevant academic articles from PubMed, EMBASE, the Cochrane Library and other libraries were selected. STATA version 13.0 (Stata Corporation, TX, USA) was used for statistical analysis. Results: We identified nine eligible papers. The study reported a significant difference in the success rate of treatment in 1 month and in 1 year, and no difference in the incidence of complications. The patients with fecaliths showed low treatment efficacy in conservative treatment group (p < 0.05). Conclusion: Standardized conservative treatment as inpatients for pediatric appendicitis is safe and feasible. Appendectomy was the better choice for patients with fecaliths.

BACKGROUND: Neural tube defects (NTDs) are birth defects of the brain, spine, or spinal cord invoked by the insufficient intake of folic acid in the early stages of pregnancy and have a complex etiology involving both genetic and environmental factors. So the study aimed to explore the association between alterations in maternal one-carbon metabolism and NTDs in the offspring. METHODS: We conducted a case-control study to get a deeper insight into this association, as well as into the role of genetic polymorphisms. Plasma concentrations of folate, homocysteine (Hcy), S-adenosylmethionine (SAM), S-adenosylhomocysteine (SAH) and genotypes and alleles distributions of 52 SNPs in 8 genes were compared for 61 women with NTDs-affected offspring and 61 women with healthy ones. RESULTS: There were significant differences between groups with regard to plasma folate, SAM, SAH and SAM/SAH levels. Logistic regression results revealed a significant association between maternal plasma folate level and risk of NTDs in the offspring. For MTHFD1 rs2236225 polymorphism, mothers having GA genotype and A allele exhibited an increased risk of NTDs in the offspring (OR = 2.600, 95%CI: 1.227-5.529; OR = 1.847, 95%CI: 1.047-3.259). For MTHFR rs1801133 polymorphism, mothers having TT and CT genotypes were more likely to affect NTDs in the offspring (OR = 4.105, 95%CI: 1.271-13.258; OR = 3.333, 95%CI: 1.068-10.400). Moreover, mothers carrying T allele had a higher risk of NTDs in the offspring (OR = 1.798, 95%CI: 1.070-3.021). For MTRR rs1801394 polymorphism, the frequency of G allele was significantly higher in cases than in controls (OR = 1.763, 95%CI: 1.023-3.036). Mothers with NTDs-affected children had higher AG genotype in RFC1 rs1051226 polymorphism than controls, manifesting an increased risk for NTDs (OR = 3.923, 95%CI: 1.361-11.308). CONCLUSION: Folic acid deficiency, MTHFD1 rs2236225, MTHFR rs1801133, MTRR rs1801349 and RFC1 rs1051226 polymorphisms may be maternal risk factors of NTDs.
