RETRACTED: Effect of laparoscopic-assisted transvaginal hysterectomy on wound complications in patients with early stage cervical cancer: A meta-analysis
Abstract
Laparoscopic-assisted vaginal radical hysterectomy (LARVH) and abdominal radical hysterectomy (ARH) have been widely applied to treat cervical carcinoma. But LARVH and ARH have not been fully investigated in treating cervical carcinoma after injury associated with injury. This research is intended to provide an up-to-date basis for comparing LARVH with ARH in early stage cervical carcinoma. Comparison between LARVH and ARH in cervical carcinoma was carried out through a combination of related research. Eligible articles from databases such as PubMed and Embase were screened using an established search strategy. This report covered the results of LARVH versus ARH in cervical carcinoma. The average difference and the 95% confidence interval (CI) were used for the combination of consecutive variables. The combination of categorical variables was performed with the odds ratio (OR) 95% confidence interval. Through the identification of 1137 publications, eight of them were chosen to be analysed. Among them, 363 were treated with LARVH and 326 were treated with ARH. Eight trials showed that LARVH was associated with a reduced risk of postoperative wound infection than ARH (OR, 0.23; 95% CI, 0.1–0.55, p = 0.0009). Five trials showed that there was no difference in the risk of postoperative bleeding after surgery (OR, 1.17; 95% CI, 0.42–3.29, p = 0.76). We also did not differ significantly in the duration of the surgery (OR, 1.79; 95% CI, −6.58 to 10.15, p = 0.68). So, the two surgical methods differ significantly only in the risk of postoperative wound infection.
1 INTRODUCTION
Cervical carcinoma is one of the most frequently fatal gynaecologic malignant tumours that affect women around the world. Over a billion new cases are diagnosed every year in Asia.1-3 Abdominal radical hysterectomy (ARH), which was first described in the past century, is now considered to be an effective therapy for early stage cervical cancer.4, 5 Along with progress in laparoscopy, laparoscopic-assisted vaginal radical hysterectomy (LARVH) became available to treat cervical carcinoma at the end of the 20th century.6, 7 The determination of an optimal treatment plan for cervical carcinoma has been difficult because of disputes about LARVH and ARH.8, 9
ARH is one of the longest-term methods, but it seems to have been linked to a greater incidence, for example, of bladder dysfunction, prolonged hospitalization and post-op infections, as demonstrated by the majority of retrospective studies.10-12 Furthermore, the results of those reviews were comparable among ARH and LARVH, resulting in broad acceptance of LARVH as a standard treatment for early stage cervical cancer.13, 14 The Laparoscopic Approach for Cervical Cancer Trial, which was released in 2018, is the first large-scale, clinical trial with ARH versus LARVH, resulting in a significant shift in the recommendations for surgery.15 Our results showed that LARVH had reduced perioperatively complications than ARH.
Thus, the application of laparoscopy in oncology has many merits such as shortened hospitalization time and fewer bleeding before operation.16 Nevertheless, LARVH has been shown to add to the complications associated with the operation, for example, the proliferation of lymphocytes and neural damage in the patients.17, 18 A recent meta-analyses of ARH and LARVH have shown that LARVH is beneficial in decreasing perioperative complications.19
A meta-analyses of past research are needed to examine the impact of ARH and LARVH on postoperative wound complications, so as to gain a better understanding of the impact of postcancer surgical treatment.
2 METHODS
2.1 Search strategy
A comprehensive and systematic search for English language articles published up to 2023 was conducted in electronic search engines such as PubMed and other databases. See Figure 1 and Table 1 for more information on the retrieval policy that is used to identify related references. The objective of this review was to find out which trials were performed in early stage cervical carcinoma to compare the results of ARH and LARVH.

2.2 Selection criteria and methods
The search strategy has been executed on the above-mentioned databases. Studies found in those databases were compared, and duplication was eliminated. The first step was to review the titles and abstracts of the study by the two researchers. Following the removal of those articles that were considered inappropriate for inclusion, the rest were examined closely. In the event that there is a disagreement among both study authors on whether to include or exclude a study, a third MA has been consulted and a consensus has been achieved. Only those trials that fulfilled the eligibility criteria were considered for this analysis. Reference lists for the inclusion of other literature have also been consulted.
2.3 Eligibility criteria
The studies covered were randomized, controlled, cohort or retrospective. In order to be enrolled, the trials in early stage cervical carcinoma were carried out to compare the results of ARH and LARVH with the results of the injury.
2.4 Exclusion criteria
Review articles were excluded. Studies with no related outcome or no comparison with the outcome of the injury following ARH or LARVH were ruled out.
2.5 Data mining and quality assessment
The data were obtained separately from the included trials by the two authors of the trial with a prevalidated data mining template. The methodology was evaluated separately by the two authors with ROBINS-I. Figures 2 and 3.


2.6 Statistical analysis
The meta-analysis was performed with Revman 5.3, which reports an effect size for the odds ratio (OR) for categorical outcomes and a weighted mean difference (MD) for consecutive outcomes. The confidence limits (Cl) were measured with 95% confidence intervals (CIs). I2 for the assessment of heterogeneity, and when I2 was greater than 50%, a random-effect model was applied. p < 0.05 was taken into account for the reporting of statistical significance. Egger's test was used to evaluate the existence of publication bias in the classification results.

3.2 Wound infection
The impact of various surgery methods on postoperative infection of cervical carcinoma was investigated in 8 studies. There was a reduction in the rate of postoperation infection in the patients who received LARVH than in those receiving ARH (OR, 0.23; 95% CI, 0.1–0.55, p = 0.0009), Figure 4.

3.3 Wound haematoma
The influence of various operative methods on the incidence of postoperative bleeding in cervical carcinoma was investigated in five studies. No significant difference was found in the risk of postoperative bleeding in patients who received LARVH or ARH (OR, 1.17; 95% CI, 0.42–3.29, p = 0.76), Figure 5.

3.4 Duration of surgery
The statistics of these three trials showed that there was no difference in operating time among the patients who had received LARVH or ARH (OR, 1.79; 95% CI, −6.58 to 10.15, p = 0.68), Figure 6.

3.5 Publication bias
Publication bias analysis of the studies on the occurrence of wound infection and haematoma in the postoperative period by different surgical procedures in patients with cervical cancer. Figures 7 and 8.


4 DISCUSSION
This research is intended to evaluate the effect of LARVH on the incidence of ARH after operation. We looked at the present research in 4 databases and found 1137 publications, eventually choosing 8 trials to be analysed. Six hundred eighty-nine cases were operated on, 363 were treated with LARVH and 326 were treated with ARH. Eight trials showed that LARVH was associated with a reduced risk of postoperative wound infection than ARH. Five trials showed that there was no difference in the risk of postoperative bleeding between two groups.
The majority of published single trials confirm that LARVH is greater than ARH operation time.28, 29 But we do not agree with earlier research that did not indicate that LARVH had a different effect on the number of operations compared with ARH. There is, however, considerable diversity between the inclusion trials, which emphasize operational time. LARVH is more skilled and skilled compared with ARH.30, 31 Thus, with the development of laparoscopy techniques and the growing expertise of the surgeon, the operating time might not be the limit of LARVH. Our hypothesis is that this heterogeneity may be due to different surgical techniques and patients' backgrounds. Prospective studies, which may be adapted to the history of the patient and the physician, are required to validate the findings. For LARVH and ARH, the two groups were compared with, for example, operating time. A similar incidence rate is supported by all published studies assessing the complications associated with both open laparoscopy and laparoscopy.25 The incidence of complications varied possibly due to differences in the standard of defining complications and duration of follow-up. Thus, it is necessary to confirm the degree of elimination of parameters and complications in future studies.
This research is limited. First of all, the English thesis and the restricted e-database are searched as the data. Thus, it is possible that some helpful information was omitted. Secondly, the majority of the research was either prospective or retrospective. Retrospective research may reduce the strength of conclusions. This might be a factor influencing the outcome of this meta-analysis.
5 CONCLUSION
In this meta-analysis, LARVH was associated with a reduced incidence of postoperative wound infection in women with cervical carcinoma than in ARH. The incidence of bleeding after operation and the time of operation were not significantly different among LARVH and ARH. This indicates that LARVH is more likely to reduce postoperative wound infections than ARH.
