Meta-Analysis
The incidence of perioperative lymphatic complications after radical hysterectomy and pelvic lymphadenectomy between robotic and laparoscopic approach : a systemic review and meta-analysis.
BACKGROUND
Although many studies have reported perioperative complications after radical hysterectomy and pelvic lymph node dissection using robotic and laparoscopic approaches, the risk of perioperative lymphatic complications has not been well identified. The aim of this meta-analysis is to compare the risks of perioperative lymphatic complications after robotic radical hysterectomy and lymph node dissection (RRHND) with laparoscopic radical hysterectomy and lymph node dissection (LRHND) for early uterine cervical cancer.
MATERIALS AND METHODS
The authors searched the PubMed, Cochrane Library, Web of Science, ScienceDirect, and Google Scholar databases for studies published up to July 2022 comparing perioperative lymphatic complications after RRHND and LRHND while treating early uterine cervical cancer. Related articles and bibliographies of relevant studies were also checked. Two reviewers independently performed the data extraction.
RESULTS
A total of 19 eligible clinical trials (15 retrospective studies and 4 prospective studies) comprising 3079 patients were included in this analysis. Only 107 patients (3.48%) had perioperative lymphatic complications, of which the most common was lymphedema ( n =57, 1.85%), followed by symptomatic lymphocele ( n =30, 0.97%), and lymphorrhea ( n =15, 0.49%). When all studies were pooled, the odds ratio for the risk of any lymphatic complication after RRHND compared with LRHND was 1.27 (95% CI: 0.86-1.89; P =0.230). In the subgroup analysis, study quality, country of research, and publication year were not associated with perioperative lymphatic complications.
CONCLUSIONS
A meta-analysis of the available current literature suggests that RRHND is not superior to LRHND in terms of perioperative lymphatic complications.

PURPOSE OF REVIEW
Primary urethral carcinoma (PUC) is a rare urologic tumor. There is limited evidence on this entity. This review summarizes the existing evidence on lymph node dissection (LND) in patients with PUC.
RECENT FINDINGS
We performed a systematic search of the PubMed, EMBASE, and Web of Science databases to evaluate the impact of inguinal and pelvic LND on the oncological outcomes of PUC and to identify indications for this procedure.
RESULTS
Three studies met the inclusion criteria. The cancer detection rate in clinically nonpalpable inguinal lymph node (cN0) was 9% in men and 25% in women. In clinically palpable lymph node (cN+), the malignancy rate was 84% and 50% in men and women, respectively. Overall cancer detection rate in pelvic lymph nodes in patients with cN0 was 29%. Based on tumor stage, the detection rate was 11% in cT1-2 N0 and 37% in cT3-4 N0. Nodal disease was associated with higher recurrence and worse survival. Pelvic LND seems to improve overall survival for patients with LND regardless of the location or stage of lymph nodes. Inguinal LND improved overall survival only in patients with palpable lymph nodes. Inguinal LND had no survival benefit in patients with nonpalpable lymph nodes.
SUMMARY
The available, albeit scarce, data suggest that inguinal LND derives the highest benefit in women and in patients with palpable inguinal nodes, whereas the benefit of pelvic LND seems to be more pronounced across all stages of invasive PUC. Prospective studies are urgently needed to further address the prognostic benefit of locoregional LND in PUC.

Meta-Analysis Review
The role of systematic pelvic and para-aortic lymphadenectomy in the management of patients with advanced epithelial ovarian, tubal, and peritoneal cancer: A systematic review and meta-analysis.
OBJECTIVE
To investigate whether systematic pelvic and para-aortic lymphadenectomy offers superior survival rates in patients with advanced epithelial ovarian cancer (EOC), tubal, or peritoneal cancer.
METHODS
We searched the electronic databases PubMed (from 1996), Cochrane Central Register of Controlled trials (from 1996), and Scopus (from 2004) to September 2021. We considered randomised controlled trials (RCTs) comparing systematic pelvic and para-aortic lymphadenectomy with no lymphadenectomy in patients with advanced EOC. Primary outcomes were overall survival and progression-free survival. Secondary outcomes were peri-operative morbidity and operative mortality. The revised Cochrane tool for randomised trials (RoB 2 tool) was utilised for the risk of bias assessment in the included studies. We performed time-to-event and standard pairwise meta-analyses, as appropriate.
RESULTS
Two RCTs with a total of 1074 patients were included in our review. Meta-analysis demonstrated similar overall survival (HR = 1.03, 95% CI [0.85-1.24]; low certainty) and progression-free survival (HR = 0.92, 95% CI [0.63-1.35]; very low certainty). Regarding peri-operative morbidity, systematic lymphadenectomy was associated with higher rates of lymphoedema and lymphocysts formation (RR = 7.31, 95% CI [1.89-28.20]; moderate certainty) and need for blood transfusion (RR = 1.17, 95% CI [1.06-1.29]; moderate certainty). No statistically significant differences were observed in regard to other peri-operative adverse events between the two arms.
CONCLUSIONS
Systematic pelvic and para-aortic lymphadenectomy is likely associated with similar overall survival and progression-free survival compared to no lymphadenectomy in optimally debulked patients with advanced EOC. Systematic lymphadenectomy is also associated with an increased risk for certain peri-operative adverse events. Further research needs to be conducted on whether we should abandon systematic lymphadenectomy in completely debulked patients during primary debulking surgery.

Meta-Analysis
OBJECTIVE
In endometrial carcinoma patients, sentinel lymph node bilateral mapping fails in 20-25% of cases, with several factors affecting the likelihood of detection. However, pooled data about predictive factors of failure are lacking. The aim of this systematic review and meta-analysis was to assess the predictive factors of sentinel lymph node failed mapping in endometrial cancer patients undergoing sentinel lymph node biopsy.
METHODS
A systematic review and a meta-analysis was performed searching all studies assessing predictive factors of sentinel lymph node failed mapping in apparent uterine-confined endometrial cancer patients undergoing sentinel lymph node biopsy through the cervical injection of indocyanine green. The associations between sentinel lymph node failed mapping and predictive factors of failure were assessed, calculating the odds ratio (OR) with 95% confidence intervals.
RESULTS
Six studies with a total of 1345 patients were included. Compared with patients with sentinel lymph node bilateral successful mapping, patients with sentinel lymph node failed mapping showed: OR 1.39 (p=0.41) for body mass index >30 kg/m; OR 1.72 (p=0.24) for menopausal status; OR 1.19 (p=0.74) for adenomyosis; OR 0.86 (p=0.55) for prior pelvic surgery; OR 2.38 (p=0.26) for prior cervical surgery; OR 0.96 (p=0.89) for prior Cesarean section; OR 1.39 (p=0.70) for lysis of adhesions during surgery before sentinel lymph node biopsy; OR 1.77 (p=0.02) for indocyanine green dose <3 mL; OR 1.28 (p=0.31) for deep myometrial invasion; OR 1.21 (p=0.42) for International Federation of Gynecology and Obstetrics (FIGO) grade 3; OR 1.89 (p=0.01) for FIGO stages III-IV; OR 1.62 (p=0.07) for non-endometrioid histotype; OR 1.29 (p=0.25) for lymph-vascular space invasion; OR 4.11 (p<0.0001) for enlarged lymph nodes; and OR 1.71 (p=0.022) for lymph node involvement.
CONCLUSION
Indocyanine green dose <3 mL, FIGO stage III-IV, enlarged lymph nodes, and lymph node involvement are predictive factors of sentinel lymph node failed mapping in endometrial cancer patients.

Meta-Analysis
OBJECTIVE
The purpose of this network meta-analysis was to compare the effectiveness and adverse effects of limited, standard, extended, and super-extended pelvic lymph node dissection (PLND) following radical prostatectomy.
METHODS
This study followed the PRISMA 2020 statement. Clinical trials were searched from three electronic databases, including PubMed, the Cochrane Library, and Embase from the database's inception to April 5, 2022. The lymph node-positive rate, biochemical recurrence-free rate, lymphocele rate, thromboembolic rate, and overall complication rate were compared by meta-analysis. Data analyses were performed using R software based on the Bayesian framework.
RESULTS
Sixteen studies involving 15,269 patients were included. All 16 studies compared the lymph node-positive rate; 5 studies compared the biochemical recurrence-free rate; 10 studies compared the lymphocele rate; 6 studies compared the thromboembolic rate, and 9 studies compared the overall complication rate. According to Bayesian analysis, the lymph node-positive rate, lymphocele rate, and overall complication rate were significantly associated with the extension of the PLND range. The limited, extended, and super-extended PLND templates showed a similar but lower biochemical recurrence-free rate and a higher thromboembolic rate than the standard template.
CONCLUSIONS
The extension of the PLND range is associated with an elevated lymph node-positive rate; however, it does not improve the biochemical recurrence-free rate and correlates with an increased risk of complications, especially lymphocele. The selection of the PLND range in clinical practice should consider the oncological risk and adverse effects.

Review
The standard treatment approach in locally advanced cervical cancer (LACC) is exclusive concurrent chemoradiation therapy (RTCT). The risk of local residual disease after six months from RTCT is about 20-30%. It is directly related to relapse risk and poor survival, such as in patients with recurrent cervical cancer. This systematic review aims to describe studies investigating salvage surgery's role in persistent/recurrent disease in LACC patients who underwent definitive RTCT. Studies were eligible for inclusion when patients had LACC with radiologically suspected or histologically confirmed residual disease after definitive RTCT, diagnosed with post-treatment radiological workup or biopsy. Information on complications after salvage surgery and survival outcomes had to be reported. The methodological quality of the articles was independently assessed by two researchers with the Newcastle-Ottawa scale. Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed, Scopus, Cochrane, Medline, and Medscape databases in May 2022. We applied no language or geographical restrictions but considered only English studies. We included studies containing data about postoperative complications and survival outcomes. Eleven studies fulfilled the inclusion criteria and all were retrospective observational studies. A total of 601 patients were analyzed concerning the salvage surgery in LACC patients for persistent/recurrent disease after RTCT treatment. Overall, 369 (61.4%) and 232 (38.6%) patients underwent a salvage hysterectomy (extrafascial or radical) and pelvic exenteration (anterior, posterior, or total), respectively. Four hundred and thirty-nine (73%) patients had histologically confirmed the residual disease in the salvage surgical specimen, and 109 patients had positive margins (overall range 0-43% of the patients). The risk of severe (grade ≥ 3) postoperative complications after salvage surgery is 29.8% (range 5-57.5%). After a median follow-up of 38 months, the overall RR was about 32% with an overall death rate of 40% after hysterectomy or pelvic exenteration with or without lymphadenectomy. There is heterogeneity between the studies both in their design and results, therefore the effect of salvage surgery on survival and recurrence cannot be adequately estimated. Future homogeneous studies with an appropriately selected population are needed to analyze the safety and efficacy of salvage hysterectomy or pelvic exenteration in patients with residual tumors after definitive RTCT.

Meta-Analysis Review
OBJECTIVES
The purpose of this systematic review and meta-analysis was to evaluate the proportion and risk factors of lymphoceles and symptomatic lymphoceles after PLND in early-stage cervical and early-stage high or high-intermediate risk endometrial cancer.
METHODS
Studies reporting on the proportion of lymphocele after PLND were conducted in PubMed, Embase and Cochrane Library. Retrieved studies were screened on title/abstract and full text by two reviewers independently. Quality assessment was conducted using the Newcastle Ottowa Scale and the Cochrane risk-of-bias tool. Proportion of lymphocele and possible risk factors were pooled through random-effects meta-analyses.
RESULTS
From the 233 studies retrieved, 24 studies were included. The pooled proportion of lymphocele was 14% and of symptomatic lymphocele was 3%. Routinely performing diagnostics was associated with a significantly higher proportion of lymphocele compared to diagnostics performed on indication (21% versus 4%, p < 0.01). Laparotomic surgical approach led to a significantly higher proportion of lymphoceles than laparoscopic surgical approach (18% versus 7%, p = 0.05). The proportion of lymphocele was significantly higher when >15% of the study population underwent additional paraaortic lymph node dissection (PAOLND) opposed to <15% (15% versus 3%, p < 0.01). A mean number of lymph nodes dissected of <21 resulted in a significantly higher pooled proportion of lymphoceles opposed to when the mean number was 21 or higher (19% versus 5%, p = 0.02). Other risk factors analysed were BMI, lymph node metastasis, adjuvant radiotherapy and follow up. There was no sufficient data to detect significant risk factors for the development of symptomatic lymphoceles.
CONCLUSION
The pooled proportion of lymphocele was 14% of which symptomatic lymphoceles occurred in 3%. Significant risk factors for the total proportion of lymphoceles were laparotomic approach, decreased number of lymph nodes dissected and additional PAOLND.

BACKGROUND
The predicament of achieving optimal surgical intervention faced by surgeons in treating ovarian cancer has driven research into improving intra-operative detection of cancer using fluorescent materials.
OBJECTIVE
To provide a literature overview on the clinical use of intra-operative fluorescence-guided surgery for ovarian cancer, either for cytoreductive surgery or sentinel lymph node (SLN) biopsy.
METHODS
The systematic review included studies from June 2002 until October 2021 from PubMed, Web of Science, and Scopus as well as those from a search of related literature. Studies were included if they investigated the use of fluorescence-guided surgery in patients with a diagnosis of ovarian cancer. Authors charted variables related to study characteristics, patient demographics, baseline clinical characteristics, fluorescence-guided surgery material, and treatment details, and surgical, oncological, and survival outcome variables. After screening 2817 potential studies, 24 studies were included.
RESULTS
Studies investigating the role of fluorescence-guided surgery to visualize tumor deposits or SLN biopsy included the data of 410 and 118 patients, respectively. Six studies used indocyanine green tracer with a mean SLN detection rate of 92.3% with a pelvic and para-aortic detection rate of 94.8% and 96.7%, respectively. The sensitivity, specificity, and positive predictive value for micrometastases detection of OTL38 and 5-aminolevulinc acid at time of cytoreduction were 92.2% vs 79.8%, 67.3% vs 94.8%, and 55.8% vs 95.8%, respectively.
CONCLUSION
Fluorescence -guided surgery is a technique that may improve the detection rate of micrometastases and SLN identification in ovarian cancer. Further research is needed to establish whether this will lead to improved patient outcomes.

Review
Lateral pelvic lymph node dissection (LPLND) in rectal cancer has gained increasing traction worldwide. Robotic LPLND is an emerging technique. Utilising the IDEAL (idea, development, exploration, assessment and long-term follow-up) framework for surgical innovation, robotic LPLND is currently at the IDEAL 2A stage (development) mainly limited to case reports, case series and videos. A systematic literature review was performed for videographic robotic LPLND. Pubmed, Ovid and Web of Science were searched with a predefined search strategy. The LapVEGAS score for peer review of video surgery was adapted for the robotic approach (RoVEGAS) and applied to measure video quality. Two reviewers independently reviewed videos and consensus reached on technical steps and learning points. Data are presented as a narrative synthesis of results. The IDEAL 2A framework was applied to videos to assess their content at the present stage of innovation. A total of 83 abstracts were identified. In accordance with the PRISMA statement, nine videos were analysed. Adherence to the complete IDEAL 2a framework was low. All videos demonstrated LPLND; however, reporting of clinical outcomes was heterogeneous and completed in six of nine videos. Histopathology was reported in six videos, with other outcomes variably reported. No videos presented patient-reported outcome measures. Two videos reported presence or absence of recurrence on follow-up. Video articles provide a valuable educational resource in dissemination and adoption of robotic techniques. Standardisation of reporting objectives are needed. Complete reporting of pathology and oncologic outcomes is required in videographic procedural-based publications to meet the IDEAL 2A framework criteria.

Review
The use of robotic surgery has increased exponentially in the United States. Despite this uptick in popularity, no standardized training pathway exists for surgical residents or practicing surgeons trying to cross-train onto the platform. We set out to perform a systematic review of existing literature to better describe and analyze existing robotic surgical training curricula amongst academic surgery programs. A systematic electronic search of the PubMed, Cochrane, and EBSCO databases was performed for articles describing simulation in robotic surgery from January 2010 to May 2022. Medical Subject Heading (MeSH) terms and keywords used to conduct this search were "Robotic," "Surgery," "Robotic Surgery," "Training," "Curriculum," "Education," and "Residency Program." A total of 110 articles were identified for the systematic review. After screening the titles and abstracts, a total of 36 full-text original articles were included in this systematic review. Of these, 24 involved robotic surgery curricula designed to teach general robotic skills, whereas the remaining 12 were for teaching procedure specific skills. Of the 24 studies involving general robotic skills, 13 included didactics as a part of the curriculum, 23 utilized virtual reality trainers, 3 used inanimate tissue, and 1 used live animal models. Of the 12 papers reviewed regarding procedure specific curricula, seven involved urologic procedures (radical prostatectomy and nephrectomy), two involved general surgical procedures (colectomy and Roux-en-Y gastric bypass surgery), two involved obstetrics and gynecology procedures (hysterectomy with myomectomy and sacrocolpopexy, hysterectomy with pelvic lymphadenectomy) and one involved a cardiothoracic surgery procedure (robotic internal thoracic artery harvest). With the rapid implementation of robotic surgery, training programs have been tasked with the responsibility of ensuring their trainees are adequately proficient in the platform prior to graduation. However, due to the lack of uniformity between surgical training programs, when it comes to robotic surgical experience, a strong need persists for a standardized national robotics training curriculum.
