RESUMO
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.
RESUMO
PURPOSE: Single incision laparoscopic appendectomy (SILA) is a widely used surgical procedure for treatment of appendicitis with better cosmesis. However, many surgeons generally tend to choose conventional multiport laparoscopic appendectomy regarding with complicated appendicitis. The aim of this study is to demonstrate the safety and feasibility of SILA for treatment of complicated appendicitis by comparison with 3-ports conventional laparoscopic appendectomy (CLA). METHODS: Retrospective chart review of patients diagnosed appendicitis at single hospital during January 2015 to May 2017 collected 500 patients. Among 134 patients with complicated appendicitis, we compared outcomes for 29 patients who got SILA and 105 patients who got CLA. RESULTS: 179 and 321 patients were treated by SILA and CLA, respectively. 134 (26.8%) patients were treated for complicated appendicitis, 29 patients by SILA and 105 patients by CLA, respectively. There was no case converted to open or added additional trocar in both groups. There were no differences in demographics with regard to age, sex, body mass index (BMI), and American society of anesthesiologists (ASA) scores. There was no difference in mean operating time (58.97±18.53 (SILA) vs. 57.57±21.48 (CLA), p=0.751). The drain insertion rate (6.9% vs 37.1%, p=0.001) and the length of hospital stay (2.76±1.41 vs. 3.97±2.97, p=0.035) were lower in SILA group with significance. There was no significant difference in the rate of surgical site infection (6.9% vs. 6.7%, p=1.000). CONCLUSION: This study demonstrates that SILA is a feasible and safe procedure for treatment of complicated appendicitis.
