Objective To determine the effect of omental flap wrapping of pancreaticoduodenectomy on postoperative pancreatic fistula and intra-abdominal bleeding in patients undergoing pancreaticiduodenectomy through meta-analysis of published studies.Methods Articles about whether omental flap wrapping could prevent postoperative pancreatic fistula and intra-abdominal bleeding were searched in databases of MEDLINE,PUBMED and EMBASE.14 English article were found and according to including and excluding criteria,4 eligible articles with a total of 2971 patients were selected.Random effects model was used to analyze odds ratios and 95％ confidence intervals (CIs).Results 1129 patients were in omental wrapping group,and 1842 patients in nonomental wrapping group.Omental roll-up during pancreaticoduodenectomy could not prevent postoperative pancreatic fistula (OR =0.81,95 ％ CI 0.40～1.63,P＞0.05) or postoperative abdominal bleeding (OR=0.67,95％ CI 0.28～1.59,P＞0.05).The sensitivity analysis showed the pancreatic fistula rate was lower in the nonomental roll-up group than that in the omental roll-up group (OR=1.24,95％ CI 1.03～1.50,P＜0.05).Conclusions Omental wrapping can not decrease the risk of pancreatic fistula and abdominal bleeding after pancreaticoduodenectomy.Further randomized controlled trials are needed to identify the effect of omental wrapping technique for pancreaticoduodenectomy.

Objective:To observe the application effect of skillful communication combined with pathway pain management on patients with hemorrhoids undergoing endoscopic sclerotherapy.Methods:Using the convenient sampling method, a total of 85 patients who received endoscopic sclerotherapy of internal hemorrhoids in the People's Hospital of Anyang City from September 2020 to August 2021 were selected as the research objects. They were divided into the intervention group (44 cases) and the control group (41 cases) . The control group was given routine nursing intervention, while the observation group was given skillful communication combined with pathway pain management on the basis of the control group. The pain level (VAS) before and 12, 24, 48, and 72 hours after the operation, as well as the negative emotions [anxiety (SAS) , depression (SDS) ], resilience (CD-RISC) and quality of life (WHOQOL-BREF) score of patients before and after the intervention were compared between the two groups.Results:Compared with before operation, the VAS scores of the intervention group at 12, 24, 48 and 72 h after operation were lower, and the VAS scores of the intervention group at each time point after operation were lower than those of the control group, and the differences were statistically significant ( P<0.05) . After the intervention, SAS and SDS scores of patients of the two groups were lower than those before the intervention, and SAS and SDS scores of the intervention group after the intervention were lower than those of the control group, and the differences were statistically significant ( P<0.05) . The scores of each dimension of CD-RISC after intervention in the two groups were higher than those before intervention, and the scores of each dimension of CD-RISC in the intervention group after intervention were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The scores of each dimension of WHOQOL-BREF in the two groups after intervention were higher than those before intervention, and the scores of each dimension of WHOQOL-BREF in the intervention group after intervention were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Skillful communication combined with pathway pain management can reduce the pain level of patients undergoing endoscopic sclerotherapy of internal hemorrhoids, relieve the negative emotions of patients and improve their psychological resilience and quality of life, which is worthy of clinical promotion.

Objective To investigate the family aggregation of human hookworm infections in Sichuan Province and to identify its influencing factors, so as to provide insights into management of hookworm infections. Methods Three to four counties (districts) were sampled from basins, hilly regions and mountainous regions around the basins in Sichuan Province from 2017 to 2022 as fixed survey sites, and 17 to 30 counties (districts) were selected as mobile survey sites. At least 1 000 permanent residents at ages of 3 years and older were sampled from each survey site, and hookworm eggs were detected in human stool samples using the Kato-Katz technique. Subjects with 2 and more family members and at least 2 individuals diagnosed with hookworm infections in the county (district) where they lived were selected, and the familial aggregation of hookworm infections was analyzed using the test of goodness of fit for binomial distribution. In addition, the knowledge and practice of hookworm disease control were investigated among residents in Hejiang County and Wutongqiao District, Leshan City, Sichuan Province in 2021 and 2022, and the difference in the knowledge and practice of hookworm disease control was compared between members with and without familial aggregation of hookworm infections. Results A total of 66 812 residents from 25 196 households were sampled from main endemic areas of hookworm diseases in Sichuan Province from 2017 to 2022 for detection of hookworm infections, and 4 403 infections were identified (6.59% prevalence). The distribution of human hookworm infections in Sichuan Province did not fit the binomial distribution, and showed family aggregations (χ² = 2 116.759, P < 0.001). Family aggregation of human hookworm infections was found in endemic areas with 1% and higher prevalence of human hookworm infections (χ² = 136.006 to 428.738, all P values < 0.001), and family aggregation of human hookworm infections was identified in different years (χ² = 87.615 to 471.838, all P values < 0.001) and in different terrains of endemic areas (χ² = 8.423 to 1 144.176, all P values < 0.001). The members with hookworm infections had median eggs per gram of 180 (interquartile range, 780) in aggregated families and 72 (102) in non-aggregated families (Z = −2.686, P < 0.05). The proportion of members in families with aggregation of hookworm infections who knew the preventive measures of hookworm disease was significantly lower than in non-aggregated families (24.49% vs. 51.72%; χ² = 10.262, P < 0.05), and the proportion of members in families with aggregation of hookworm infections who often worked barefoot on the ground was significantly higher than in non-aggregated families (30.61% vs. 13.25%; χ² = 6.289, P < 0.05). Conclusions There is a familial aggregation of human hookworm infections in Sichuan Province, and awareness of preventive measures for hookworm disease and frequent working barefoot on the ground are associated with familial aggregation of hookworm infections.
