ABSTRACT
Objective:To analyze the effects of umbilical laparoendoscopic single-site surgery (U-LESS) and conventional laparoscopic appendectomy (CLS) on the treatment of acute appendicitis in children by using Meta-analysis. To evaluate the effectiveness and safety of U-LESS in treating acute appendicitis in children.Methods:The English databases Pubmed, Web of Science, the Cochrane Library, Clinical trials, CNKI, Weipu Database, Wanfang Medical Network Database, CBM literature and other Chinese databases were retrieved, and the relevant literature of the comparative study of U-LESS and CLS in the treatment of pediatric acute appendicitis was found, and the quality analysis and application of the selected comparative studies were carried out. RevMan5.3 and stata software were employed to compare the operation time, intraoperative blood loss, postoperative exhaust time, postoperative intestinal recovery time, incision length, postoperative hospital stay time, postoperative complications, etc. of different surgical procedures.Results:A total of 19 literature were included in this study, and a total of 2133 cases were included, including 1021 cases in the U-LESS group and 1112 cases in the CLS group, all of which were retrospective case-control studies. Meta analysis showed that the operation time in U-LESS was shorter than that in CLS (95%CI [-9.05, -3.17], Z=4.07, P<0.001) , and the intraoperative bleeding volume of U-LESS was less than that of CLS (95%CI [-15.28, -5.01], Z=3.87, P<0.001) , incision length was shorter in U-LESS than in CLS (95%CI [-1.40, -1.27], Z=39.30, P<0.001) , the postoperative exhaust time of U-LESS was shorter than that of CLS (95%CI [-8.63, -5.89], Z=10.37, P<0.001) , and the recovery time after U-LESS was shorter than that after CLS (95% CI, 95% CI, P<0.001) . U-LESS and CLS did not differ significantly in postoperative length of stay (95%CI [-1.33, -0.64], Z=5.61, P<0.001) . U-LESS had fewer postoperative complications compared with CLS (95%CI [0.24,0.52], Z=5.27, P<0.001) . Conclusion:For pediatric acute appendicitis, U-LESS is safe and feasible, and has the advantages of shortening the operation time and reducing intraoperative bleeding.
ABSTRACT
ObjectiveTo assess the effectiveness and prognosis of different radical surgery for Hirschsprung disease (HD).MethodsThe bowel function of HD patients undergoing the anus modified Soave operation (84 cases,modified Soave group),modified Swenson operation (60 cases,modified Swenson group),modified Duhamel operation (76 cases,modified Duhamel group) was followed up by 3,6 months and 2 years after surgery.Long-term bowel function,clinical type,removal length,anorectal manometry,barium enema were analyzed and compared among three groups.ResultsThe occurrence rates of bowel dysfunction 3,6 months and 2 years after surgery in modified Soave group[17.9％(15/84),7.1％(6/84),4.8％ (4/84)] were significantly lower than those in modified Swenson group[41.7％ (25/60),21.7％(13/60),18.3％(11/60) ] and modified Duhamel group [ 36.8％ (28/76),18.4％ (14/76),13.2％(10/76) ].There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group(P＜ 0.05 ).There was no significant difference between modified Swenson group and modified Duhamel group (P ＞ 0.05).When the removal length ≤35 cm,the occurrence rate of bowel dysfunction after surgery in modified Soave group [ 18.7％ (14/75)] was lower than that in improved Swenson group [ 39.5％ ( 17/43 ) ] and modified Duhamel group [ 34.4％ (21/61 ) ].There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group (P ＜ 0.05).There was no significant difference between modified Swenson group and modified Duhamel group (P ＞ 0.05).When the removal length ＞ 35 cm,there was no significant difference in the occurrence rate of bowel dysfunction after surgery among three groups (P ＞ 0.05 ).The occurrence rates of bowel dysfunction in short-segment type and common type in modified Soave group was lower than those in modified Swenson group and modified Duhamel group.There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group(P ＜ 0.05).There was no significant difference between modified Swenson group and modified Duhamel group (P＞ 0.05).The anorectal angle 2 years after surgery in modified Soave group [(93.67 ± 10.50)° ] was less than that in modified Swenson group [(110.20 ± 11.88)° ] and modified Duhamel group [(106.33 ± 12.21)° ].There was significant difference (P ＜0.05).ConclusionThe complication and trauma are significantly lower in the anus modified Soave operation than the modified Swenson operation and modified Duhamel operation,but the choice of surgery should be strictly controlled according to the anal HD treatment indications.
