Laparoscopic appendectomy with single port vs conventional access: systematic review and meta-analysis of randomized clinical trials

Abstract

Background Conventional three-access laparoscopic appendectomy (CLA) is currently the gold standard treatment, however, Single-Port Laparoscopic Appendectomy (SILA) has been proposed as an alternative. The aim of this systematic review/meta-analysis was to evaluate safety and efficacy of SILA compared with conventional approach. Methods Per PRISMA guidelines, we systematically reviewed randomised controlled trials (RCTs) comparing CLA vs SILA for acute appendicitis. The randomised Mantel–Haenszel method was used for the meta-analysis. Statistical data analysis was performed with the Review Manager software and the risk of bias was assessed with the Cochrane "Risk of Bias" assessment tool. Results Twenty-one studies (RCTs) were selected (2646 patients). The operative time was significantly longer in the SILA group (MD = 7,32), confirmed in both paediatric (MD = 9,80), (Q = 1,47) and adult subgroups (MD = 5,92), (Q = 55,85). Overall postoperative morbidity was higher in patients who underwent SILA, but the result was not statistically significant. In SILA group were assessed shorter hospital stays, fewer wound infections and higher conversion rate, but the results were not statistically significant. Meta-analysis was not performed about cosmetics of skin scars and postoperative pain because different scales were used in each study. Conclusions This analysis show that SILA, although associated with fewer postoperative wound infection, has a significantly longer operative time. Furthermore, the risk of postoperative general complications is still present. Further studies will be required to analyse outcomes related to postoperative pain and the cosmetics of the surgical scar.

The Study of Comparison of Single-Incision Laparoscopic Versus Conventional Laparoscopic Appendectomy: A Comprehensive Systematic Review

“…A thorough three-level screening strategy was used to identify only five papers as directly relevant to our ongoing Wrong intervention (1) systematic evaluation. Next, a thorough study of the entire text and further examination of these articles were selected.…”

“…Potential disadvantages of SILA include loss of triangulation, impaired vision, intra/extra abdominal instrument conflicts, and device cost. [1][2][3] Acute appendicitis is one of the most common causes of emergency gastrointestinal surgery worldwide. Even though controversy regarding the medical management of acute appendicitis using antibiotics exists, appendectomy is currently considered the gold standard treatment.…”

Efficacy and Safety of Minimally Invasive Surgery Techniques in The Treatment of Acute Appendicitis: A literature review.

“…Cirocchi et al contrasted traditional three-access laparoscopic appendectomy (CLA) with laparoscopic appendectomy with single-port access (SILA) in their systematic review and meta-analysis (18) . The purpose of the research was to evaluate SILA's effectiveness and safety as a substitute for the traditional method.…”
