Meta-Analysis Review
BACKGROUND
Incontinence can have a devastating effect on the lives of sufferers with significant economic implications. Non-surgical treatments such as pelvic floor muscle training and the use of mechanical devices are usually the first line of management, particularly when a woman does not want surgery or when she is considered unfit for surgery. Mechanical devices are inexpensive and do not compromise future surgical treatment.
OBJECTIVES
To determine whether mechanical devices are useful in the management of adult female urinary incontinence.
SEARCH METHODS
For this second update we searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 21 August 2014), EMBASE (January 1947 to 2014 Week 34), CINAHL (January 1982 to 25 August 2014), and the reference lists of relevant articles.
SELECTION CRITERIA
All randomised or quasi-randomised controlled trials of mechanical devices in the management of adult female urinary incontinence determined by symptom, sign or urodynamic diagnosis.
DATA COLLECTION AND ANALYSIS
The reviewers assessed the identified studies for eligibility and risk of bias and independently extracted data from the included studies. Data analysis was performed using RevMan software (version 5.3).
MAIN RESULTS
One new trial was identified and included in this update bringing the total to eight trials involving 787 women. Three small trials compared a mechanical device with no treatment and although they suggested that use of a mechanical device might be better than no treatment, the evidence for this was inconclusive. Four trials compared one mechanical device with another. Quantitative synthesis of data from these trials was not possible because different mechanical devices were compared in each trial using different outcome measures. Data from the individual trials showed no clear difference between devices, but with wide confidence intervals. One trial compared three groups: a mechanical device alone, behavioural therapy (pelvic floor muscle training) alone and behavioural therapy combined with a mechanical device. While at three months there were more withdrawals from the device-only group, at 12 months differences between the groups were not sustained on any measure.
AUTHORS' CONCLUSIONS
The place of mechanical devices in the management of urinary incontinence remains in question. Currently there is little evidence from controlled trials on which to judge whether their use is better than no treatment and large well-conducted trials are required for clarification. There was also insufficient evidence in favour of one device over another and little evidence to compare mechanical devices with other forms of treatment.

Review
AIM
To analyze the anatomy of sacral venous plexus flow, the causes of injuries and the methods for controlling presacral hemorrhage during surgery for rectal cancer.
METHODS
A review of the databases MEDLINE and Embase™ was conducted, and relevant scientific articles published between January 1960 and June 2016 were examined. The anatomy of the sacrum and its venous plexus, as well as the factors that influence bleeding, the causes of this complication, and its surgical management were defined.
RESULTS
This is a review of 58 published articles on presacral venous plexus injury during the mobilization of the rectum and on techniques used to treat presacral venous bleeding. Due to the lack of cases published in the literature, there is no consensus on which is the best technique to use if there is presacral bleeding during mobilization in surgery for rectal cancer. This review may provide a tool to help surgeons make decisions regarding how to resolve this serious complication.
CONCLUSION
A series of alternative treatments are described; however, a conventional systematic review in which optimal treatment is identified could not be performed because few cases were analyzed in most publications.

Review
INTRODUCTION
Stress urinary incontinence (SUI) is a common disorder in women that has a negative impact on quality of life. Pregnancy and childbirth are considered important risk factors that directly affect the pelvic floor during pregnancy and labour, increasing the risk of pelvic floor dysfunction, with prevalence rates of SUI in the postpartum period ranging from 30 to 47% during the first 12 months.
OBJECTIVE
To determine the effectiveness of pelvic floor muscle training (PFMT) in the prevention of SUI in women during the antenatal and postnatal period by reviewing and evaluating the available scientific literature.
METHODS
This is a systematic review, using only randomised controlled trials. We searched the databases Pubmed, Scopus, Cochrane and PEDro. We reviewed 7 prospective studies in English and Portuguese, which included 1,401 pregnant women of legal age who underwent PFMT to prevent SUI.
RESULTS
The results allowed us to establish that PFMT is used for pelvic floor muscles and that this intervention, applied with the appropriate methodology, can prevent or cure SUI.
CONCLUSIONS
The application of PFMT in an early stage of pregnancy has positive effects on the continence capacity after delivery.

Meta-Analysis Review
A systematic review and metaanalysis of open, conventional laparoscopic and robot-assisted laparoscopic techniques for re-do pyeloplasty for recurrent uretero pelvic junction obstruction in children.
OBJECTIVE
About 3% of primary pyeloplasties may require a re-do pyeloplasty for recurrent uretero pelvic junction obstruction (UPJO) making it an uncommon operation even in large volume centers. In this MA we have compared the outcomes of open (OP), laparoscopic (LP) and robot assisted LP (RALP) approaches in managing recurrent UPJO.
METHODS
Pubmed/Index medicus etc. were searched for re-do pyeloplasty (Open OR Laparoscopic OR Robot-assisted) AND (Redo OR Reoperative OR failed) AND (child OR pediatric OR paediatric), for articles published between 2001 and 2021. Duplicate publications were identified and removed. Articles with grossly incomplete data and errors in reporting were excluded, as were articles reporting <5 cases. The systematic review was carried out according to PRISMA guidelines and meta-analysis of proportions was carried out using MetaXL 5.3.
RESULTS
A total of 18 articles on re-do pyeloplasty were included in the analysis. In total, there were 87, 77 and 123 redo pyeloplasties in OP, LP and RALP groups respectively. The I2 statistics for OP, LP and RALP showed low heterogeneity with I2 of 24%, 0% and 20% respectively. LFK index was 0.88, 0.30 and 1.62 for OP, LP and RALP respectively, suggesting no or minor publication bias. The overall success rates of OP, LP and RALP re-do pyeloplasty were 93.1% (95% CI 86-98), 92.1% (95% CI 83-96) and 89.4% (95% CI 83-96) respectively (summary table). The success rate between the techniques was not significantly different, with p values (x) of 1 (OP vs LP), 0.5 (OP vs RALP) and 0.6 (LP vs RALP). Overall, redo RALP took significantly longer time than redo LP (p < 0.001, Fisher's). Overall, RALP had significantly shorter hospital stay than LP (p < 0.001) and LP had significantly shorter hospital stay than OP (p < 0.001). The complication rate was 9% in OP and LP and 16% in RALP, the difference being not statistically significant (p value 1, 0.26 and 0.27 for OP vs LP, OP vs RALP and LP vs RALP respectively, x).
CONCLUSIONS
In conclusion MIS techniques (LP and RALP) seem to be good alternatives to OP for redo pyeloplasty in children, with comparable success and complications. Redo RALP had longer duration of surgery but shorter hospital stay than redo LP. With comparable success & complication rate between RALP and LP, this MA could not favor one over the other for redo pyeloplasty.

Review
BACKGROUND
Pelvic organ prolapse (POP) is the descent of a woman's uterus, bladder, or rectum into the vagina. It affects 50% of women over 50 years old who have given birth to at least one child, and recognised risk factors are older age, higher number of births, and higher body mass index. This review assesses the effects of oestrogen therapy, alone or in combination with other treatments, on POP in postmenopausal women.
OBJECTIVES
To assess the benefits and harms of local and systemic oestrogen therapy in the management of pelvic organ prolapse symptoms in postmenopausal women, and to summarise the principal findings of relevant economic evaluations.
SEARCH METHODS
We searched the Cochrane Incontinence Specialised Register (up to 20 June 2022), which includes CENTRAL, MEDLINE, two trials registers, and handsearching of journals and conference proceedings. We also checked the reference lists of relevant articles for additional studies.
SELECTION CRITERIA
We included randomised controlled trials (RCTs), quasi-RCTs, multi-arm RCTs, and cross-over RCTs that evaluated the effects of oestrogen therapy (alone or in combination with other treatments) versus placebo, no treatment, or other interventions in postmenopausal women with any grade of POP.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data from the included trials using prespecified outcome measures and a piloted extraction form. The same review authors independently assessed the risk of bias of eligible trials using Cochrane's risk of bias tool. Had data allowed, we would have created summary of findings tables for our main outcome measures and assessed the certainty of the evidence using GRADE.
MAIN RESULTS
We identified 14 studies including a total of 1002 women. In general, studies were at high risk of bias in terms of blinding of participants and personnel, and there were also some concerns about selective reporting. Owing to insufficient data for the outcomes of interest, we were unable to perform our planned subgroup analyses (systemic versus topical oestrogen, parous versus nulliparous women, women with versus without a uterus). No studies assessed the effects of oestrogen therapy alone versus no treatment, placebo, pelvic floor muscle training, devices such as vaginal pessaries, or surgery. However, we did identify three studies that assessed oestrogen therapy in conjunction with vaginal pessaries versus vaginal pessaries alone and 11 studies that assessed oestrogen therapy in conjunction with surgery versus surgery alone.
AUTHORS' CONCLUSIONS
There was insufficient evidence from RCTs to draw any solid conclusions on the benefits or harms of oestrogen therapy for managing POP symptoms in postmenopausal women. Topical oestrogen in conjunction with pessaries was associated with fewer adverse vaginal events compared with pessaries alone, and topical oestrogen in conjunction with surgery was associated with reduced postoperative urinary tract infections compared with surgery alone; however, these findings should be interpreted with caution, as the studies that contributed data varied substantially in their design. There is a need for larger studies on the effectiveness and cost-effectiveness of oestrogen therapy, used alone or in conjunction with pelvic floor muscle training, vaginal pessaries, or surgery, for the management of POP. These studies should measure outcomes in the medium and long term.

Review
OBJECTIVE
The purpose of this study was to describe the genesis of the AO Spine Sacral and Pelvic Classification System in the context of historical sacral and pelvic grading systems.
METHODS
A systematic search of MEDLINE, EMBASE, Google Scholar, and Cochrane databases was performed consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify all existing sacral and pelvic fracture classification systems.
RESULTS
A total of 49 articles were included in this review, comprising 23 pelvic classification systems and 17 sacral grading schemes. The AO Spine Sacral and Pelvic Classification System represents both the evolutionary product of these historical systems and a reinvention of classic concepts in 5 ways. First, the classification introduces fracture types in a graduated order of biomechanical stability while also taking into consideration the neurological status of patients. Second, the traditional belief that Denis central zone III fractures have the highest rate of neurological deficit is not supported because this subgroup often includes a broad spectrum of injuries ranging from a benign sagittally oriented undisplaced fracture to an unstable "U-type" fracture. Third, the 1990 Isler lumbosacral system is adopted in its original format to divide injuries based on their likelihood of affecting posterior pelvic or spinopelvic stability. Fourth, new discrete fracture subtypes are introduced and the importance of bilateral injuries is acknowledged. Last, this is the first integrated sacral and pelvic classification to date.
CONCLUSIONS
The AO Spine Sacral and Pelvic Classification is a universally applicable system that redefines and reorders historical fracture morphologies into a rational hierarchy. This is the first classification to simultaneously address the biomechanical stability of the posterior pelvic complex and spinopelvic stability, while also taking into consideration neurological status. Further high-quality controlled trials are required prior to the inclusion of this novel classification within a validated scoring system to guide the management of sacral and pelvic injuries.

BACKGROUND
Staging laparoscopy for gastric cancer is recommended to assess the tumor's locoregional extension and exclude peritoneal disease. As there is no consensus on optimizing the procedure's diagnostic accuracy, we aimed to systematically review the literature on operative techniques, followed by peritoneal lavage fluid assessment in gastric cancer patients. Specifically, we sought to indicate the most common characteristics of the procedure and cytological evaluation.
METHODS
This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol for this systematic review was registered on PROSPERO database (CRD: 42022306746). On September 2022, a search was carried out using Embase, Medline ALL, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection.
RESULTS
The search identified 1632 studies on staging laparoscopy and 2190 studies on peritoneal fluid assessment. Some 212 studies were included. Open Hasson was the method of choice in accessing the peritoneal cavity in 65% of the studies, followed by establishing a pneumoperitoneum at 10-12 mmHg in 52% of reports. Most frequently, the patient was positioned supine (70%), while a 30° scope and three ports were used to assess the peritoneal cavity clockwise (72%, 77%, and 85%, respectively). Right and left upper abdomen quadrants were the predominant area of laparoscopic exploration (both 65%), followed by the primary tumor region (54%), liver and pelvis (both 30%), and small bowel and spleen (19% and 17%, respectively). Regions of peritoneal lavage and aspiration were limited to the pelvis (50%), followed by right and left upper abdomen quadrants (37.5% and 50%, respectively). No studies compared different methods of operative techniques or analysis of ascites/fluid.
CONCLUSIONS
This study indicates a high heterogeneity in the technique of staging laparoscopy and peritoneal fluid assessment in gastric cancer patients. Further research and initiatives to reach a consensus on the standardization of the procedure are warranted.

Meta-Analysis Review
PURPOSE
There are conflicting findings about the effect of resection margins on local recurrence in osteosarcoma after surgery. In this meta-analysis, we examined the association between local recurrence and resection margins for osteosarcoma in extremity and pelvis.
METHODS
EMBASE, PubMed and Cochrane CENTRAL were searched from January 1980 to July 2016. The quality of included studies was evaluated using the Newcastle-Ottawa Quality Assessment Scale. The odds ratio and 95% confidence interval of local recurrence were estimated, respectively, for inadequate vs adequate margins and marginal vs wide margins using a random-effect model. Chi-square test was performed to comparing the local recurrence rate between extremity and pelvic osteosarcomas with an identical surgical margin.
RESULTS
Thirteen articles involving 1559 patients (175 with and 1384 without local recurrence) were included in this study. The meta-analysis showed that the osteosarcoma resected with inadequate and marginal margins, whether in extremity or in pelvis, were associated with a significantly higher local recurrence rate than the osteosarcoma resected with adequate and wide margins, respectively. Chi-square test showed that, when pelvic and extremity osteosarcomas were removed with an identical resection margin, the local recurrence was significantly more frequent in pelvis osteosarcoma than in extremity osteosarcoma.
CONCLUSION
This study provides level IIa evidence to support that the surgery with adequate or wide resection margin has positive effect on reducing the risk of local recurrence in osteosarcoma. In addition, the factors independent of resection margin are more likely to increase the risk of local recurrence in pelvic osteosarcoma.
LEVEL OF EVIDENCE
Level IIa, Therapeutic study.

Review
Medical use of (non-)thermal plasmas is an emerging field in gynaecology. However, data on plasma energy dispersion remain limited. This systematic review presents an overview of plasma devices, fields of effective application, and impact of use factors and device settings on tissues in the female pelvis, including the uterus, ovaries, cervix, vagina, vulva, colon, omentum, mesenterium, and peritoneum. A search of the literature was performed on 4 January 2023 in the Medline Ovid, Embase, Cochrane, Web of Science, and Google Scholar databases. Devices were classified as plasma-assisted electrosurgery (ES) using electrothermal energy, neutral argon plasma (NAP) using kinetic particle energy, or cold atmospheric plasma (CAP) using non-thermal biochemical reactions. In total, 8958 articles were identified, of which 310 were scanned, and 14 were included due to containing quantitative data on depths or volumes of tissues reached. Plasma-assisted ES devices produce a thermal effects depth of <2.4 mm. In turn, NAP effects remained superficial, <1.0 mm. So far, the depth and uniformity of CAP effects are insufficiently understood. These data are crucial to achieve complete treatment, reduce recurrence, and limit damage to healthy tissues (e.g., prevent perforations or preserve parenchyma). Upcoming and potentially high-gain applications are discussed, and deficits in current evidence are identified.

Meta-Analysis Review
PURPOSE
The aim of this study is to evaluate the role of pelvic intraoperative neuromonitoring (pIONM) in rectal cancer surgery.
METHODS
A systematic review of the literature and a meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions.
RESULTS
Overall, nine studies were identified. Quantitative analysis was performed only in three trials. Bilateral pIONM improved postoperative anorectal and urogenital functional outcomes. However, unilateral pIONM displayed a significant effect only on erectile function (p = 0.001).
CONCLUSIONS
Our findings suggest a positive effect of pIONM on postoperative functional outcomes and quality of life after rectal cancer surgery. Due to several limitations, further trials are required in order to elucidate the exact role of pIONM.
