Review
BACKGROUND
Traditional open orchiopexy is still a standard of treatment for palpable undescended testicles. Recently several authors reported successful results using a laparoscopic approach in the treatment of palpable cryptorchidism. The present systematic review and meta-analysis investigated the utility of laparoscopic orchiopexy for palpable cryptorchidism.
METHODS
Scientific databases (PubMed, Scopus, Web of Science, and EMBASE) were systematically searched for relevant articles using the following terms: (palpable cryptorchidism or palpable undescended testes) AND (laparoscopic orchiopexy or laparoscopic orchiopexy). The inclusion criteria were all children with unilateral or bilateral palpable undescended testes who underwent laparoscopic orchiopexy (LO) compared to children who underwent conventional open orchiopexy (CO). The main outcomes were the proportion of children requiring redo-orchiopexy and the incidence of postoperative complications. Secondary outcomes were duration and the cost of surgery.
RESULTS
The final meta-analysis included five studies involving 705 children; LO, = 369 (52.3%) and CO, = 336 (47.7%). The majority of the included patients had unilateral palpable cryptorchidism. No significant differences were found in regard to average age at the time of surgery and follow-up periods between the investigated groups. No statistically significant differences were found in regard to redo-orchiopexy rates (RR = 0.22, 95% CI 0.03-1.88, = 0.17), early complications (RR = 0.66, 95% CI 0.21-2.08, = 0.48) and incidence of testicular atrophy (RR = 0.36, 95% CI 0.03-3.88, = 0.40). No significant differences in the operative duration were observed among the groups. Laparoscopy was associated with higher costs in most of the studies.
CONCLUSION
LO is safe and effective in children with palpable cryptorchidism. The rates of redo-orchiopexy as well as an incidence of early complications and testicular atrophy rates are comparable to CO.

Meta-Analysis Review
PURPOSE
Cryptorchidism associated with gastroschisis has been poorly investigated. We aimed to assess the prevalence of this association, and to address the management and outcome of cryptorchidism in this context.
MATERIALS AND METHODS
In this systematic review, we searched electronic databases (PubMed, Web of Science, and Google Scholar), without language restrictions from inception to March 31, 2021, for studies on cryptorchidism and gastroschisis co-occurrence. Random effects meta-analysis was used to calculate pooled prevalence estimates of cryptorchidism in gastroschisis and spontaneous testicular descent in this population.
RESULTS
Twenty-five studies were included for the systematic review. All were retrospective case reports or series for a total of 175 patients. Pooled prevalence estimate for cryptorchidism in gastroschisis was 19% (95% CI 13-26). Complete data sets for management and outcome analysis were available in 94 patients, involving 120 undescended testes [63 (52.5%) nonpalpable, 34 (28.3%) prolapsed outside the abdominal wall defect, and 23 (19.2%) palpable]. Fifty-five descended spontaneously, with a pooled prevalence estimate of 50% (95% CI 31-69). Twelve testes/remnants were primarily removed or absent, while 49 testes underwent orchiopexy (success rate, 63%). Excluding 4 testes still awaiting orchiopexy, 30 of the remaining 116 (25.8%) testes had a dismal outcome, including testicular loss (19), hypoplasia (8) or recurrent cryptorchidism (3).
CONCLUSION
Cryptorchidism in gastroschisis appears to occur more frequently than in the normal population. The overall mediocre testicular outcome seems to reflect the most unfavorable presentation of cryptorchidism in gastroschisis, which is represented by originally intrabdominal or prolapsed testis in the majority of cases.

Review
PURPOSE
The purpose of this study is to study the main epidemiological, clinical, para clinical, pathological, therapeutic, and evolutionary features of patients with testicular neuroendocrine tumors (TNET).
MATERIALS AND METHODS
Nine case series and sixteen case reports were identified by searching PubMed database and qualified for inclusion in this study. We added the data of one case treated in the department of urology in Habib Bourguiba Hospital in Sfax, to the published cases.
RESULTS
A total of 132 cases were collected. Median age at diagnosis was 39 years old (range 10- 83 years). The most common presenting symptom was either a testicular mass or a swelling in 38.46% of cases. Carcinoid syndrome was documented in 10.60% of patients. The clinical examination revealed a palpable mass in 44.70% of patients. This mass was painless and firm in most cases. Serum tumor markers (β-gonadotrophine chorionique humaine, α-feto protein, and lactate dehydrogenase) were within normal limits in all patients except in one case. Most testicular neuroendocrine tumors (76.52%) were primary and pure. The tumors were positive for chromogranin (100%), synaptophysin (100%) and cytokeratin (93.10%). Metastases were detected at time of diagnosis in eight cases (6.06%). The main treatment was radical orchiectomy performed in 127 patients (96.21%). The 5-year overall survival rate was 78.70% and the 5-year specific survival rate was 84.30%.
CONCLUSION
The diagnosis of testicular carcinoids is based on the immunohistochemistry study. The treatment of choice for these tumors is radical orchiectomy. Somatostatin analogues were reported to be effective in patients with carcinoid syndrome.

Review
(1) Background: In the last few years, technological developments in the surgical field have been rapid and are continuously evolving. One of the most revolutionizing breakthroughs was the introduction of the IoT concept within surgical practice. Our systematic review aims to summarize the most important studies evaluating the IoT concept within surgical practice, focusing on Telesurgery and surgical Telementoring. (2) Methods: We conducted a systematic review of the current literature, focusing on the Internet of Surgical Things in Telesurgery and Telementoring. Forty-eight (48) studies were included in this review. As secondary research questions, we also included brief overviews of the use of IoT in image-guided surgery, and patient Telemonitoring, by systematically analyzing fourteen (14) and nineteen (19) studies, respectively. (3) Results: Data from 219 patients and 757 healthcare professionals were quantitively analyzed. Study designs were primarily observational or based on model development. Palpable advantages from the IoT incorporation mainly include less surgical hours, accessibility to high quality treatment, and safer and more effective surgical education. Despite the described technological advances, and proposed benefits of the systems presented, there are still identifiable gaps in the literature that need to be further explored in a systematic manner. (4) Conclusions: The use of the IoT concept within the surgery domain is a widely incorporated but less investigated concept. Advantages have become palpable over the past decade, yet further research is warranted.

Review
BACKGROUND
The technique of prostate biopsy has evolved a long way since its inception to being a safe diagnostic procedure. The principles of the biopsy technique continue to improvise with the knowledge about prostate cancer and availability of newer treatment options like active surveillance and focal therapy. Currently, we depend on accurate cancer information from the biopsy more than ever for deciding the ideal treatment option.
AIM
The aim of this review is to present the major milestones in prostate biopsy technique evolutions and its impact on the prostate cancer management.
ACQUISITION OF EVIDENCE
We performed a detailed non-systematic literature review to present the historical facts on the transformations in prostate biopsy techniques and also the direction of present research to improve accurate cancer detection.
SUMMARY OF EVIDENCE
There is a clear change in trend in biopsy technique before and after the introduction of transrectal ultrasound and prostate specific antigen. In the earlier era, the biopsies were aimed at palpable nodules and obtaining adequate prostatic tissue for diagnosis while the later era has moved towards detection of non-palpable and early prostate cancer. Recently, there is an increasing trend towards image guided targeted biopsies to extract maximum cancer information from minimum biopsy cores.
CONCLUSION
Prostate biopsy techniques have seen major changes since its inception and have a major impact on prostate cancer management. There is a great potential for research which can further support the newer treatment options like focal therapy.

Meta-Analysis
INTRODUCTION
Krukenberg tumor (KT) is defined as a secondary neoplasm of the ovary. While ovarian metastases account for about 30% of ovarian tumors, KTs are rare, accounting for about 1-2% of the total. The rarity of KT is at least in part responsible for the lack of a precise clinic-pathological characterization of these tumors. Clinically, KT may have a subtle clinical presentation, with few symptomatic manifestations and nonspecific clinical signs, even though in literature there is disagreement about the clinical presentation of these patients; such difficulties in the diagnostic framework often leads to a delayed diagnosis with serious consequences on the patient outcome. We aimed to provide a clinico-pathological characterization of Krukenberg Tumor (KT) through a systematic review and meta-analysis to improve the diagnosis and management of KT.
EVIDENCE ACQUISITION
Electronic databases were searched for all studies assessing clinico-pathological features of KT series. Pooled prevalence of each clinical or pathological factor was calculated according to the random-effect model.
EVIDENCE SYNTHESIS
Forty-eight studies with 3025 KT patients were included; 39.7% of patients were ≥50 and 39.8% were postmenopausal. The most common primary tumor sites were stomach (42.5%), colon-rectum (26.1%), breast (9.3%), and appendix (5%); 48.7% of KTs were synchronous with the primary tumor, 64.3% were bilateral, 40.5% had a diameter ≥10 cm; 55.3% showed extraovarian extent and 49% showed peritoneal involvement. The most common presenting symptoms were ascites (51.7%), palpable mass (31.3%), pain (29.3%), abdominal distention (28.7%), irregular bleeding (9.1%), asymptomatic (11.2%).
CONCLUSIONS
KT shows a highly variable presentation. Understanding the prevalence of clinico-pathological factors may be helpful to improve the diagnosis and management of KT.

Review
. Cervical lymphadenopathy in children is common and its etiologies diverse. No systematic review of the differential diagnosis of pediatric cervical lymphadenopathy has been conducted. . To determine the prevalence rate of specific etiologies of pediatric cervical lymphadenopathy. . EMBASE, PubMed, and SCOPUS were searched electronically. Bibliographies of select studies were reviewed as well. . (1) Any clinical trial, observational study, or cross-sectional case series with 10 or more subjects that included delineation of etiologies and/or associated conditions with lymphadenopathy; (2) subjects aged 0 to 21 years with enlarged lymphoid tissue on body; (3) lymphadenopathy was confirmed by clinical evaluation; and (4) no specific diagnoses were excluded. . Year and location of publication, definition of lymphadenopathy, percentage of lymphadenopathy that was cervical, total number of subjects, gender distribution of subjects, age range of patients, and specific etiologies. . Of the 1790 studies, 7 studies that were combined resulted in 2687 subjects that were selected. Nonspecific benign etiology was the most common diagnosis occurring at a rate of 67.8%. Epstein-Barr virus was the next most prevalent (8.86%), followed by malignancy (4.69%) and granulomatous disease (4.06%). The most common malignancy etiology was non-Hodgkin's lymphoma (46.0%), and the most common granulomatous disease was tuberculosis (73.4%). . This systematic review and meta-analysis provides a rate-based differential diagnosis of pediatric cervical lymphadenopathy. Although the most common causes of pediatric cervical lymphadenopathy are nonspecific, the etiologies are diverse. Rates and credible intervals are provided to enable a probability-based diagnostic approach to palpable cervical lymphadenopathy in this age group.

Meta-Analysis Review
Breast cancer screening has seen an increase in the detection of non-palpable breast lesions. Wire guided localisation (WGL) and Radio-guided occult lesion localisation (ROLL) are well established modalities of localisation of non-palpable breast lesions in the UK. We aimed to compare the outcomes of WGL and ROLL in this updated meta-analysis. We searched Cochrane Central Register of Controlled Trials (CENTRAL), and LILACS using free text search words as well as relevant MESH-terms. We also searched Medline (02/03/2021), Embase and registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Outcomes considered were re-excision rates, margin involvement, specimen volume and weight, accurate localisation of lesions and operative time. We assessed the risk of bias in included studies and performed random effects meta-analyses using Review Manager (version 5.3). Heterogeneity was estimated using the I-statistic. Nine included studies enrolled 1096 patients undergoing localization in breast surgery (534 in WGL and 562 in ROLL). There was a statistically significant benefit in favour of ROLL for non-involved resection margins (OR 0.60; 95% CI, 0.44-0.97); based on seven studies. Nine trials assessed operative time favouring ROLL (OR 1.95; 95% CI, 0.27-3.63). No significant difference in re-excision rates was reported (OR 1.42; 95% CI, 0.83-2.43) based on seven studies. Current evidence favourably supports ROLL, compared to WGL, with respect to margin involvement, localisation and operative time in the treatment of non-palpable breast lesions.

Meta-Analysis Review
Pre-operative localization of non-palpable breast lesions with non-wired non-ionizing (NWNI) techniques may improve clinical outcomes as reoperation rate, cosmetic outcome and contribute to organizational aspects improvement in breast-conserving surgery (BCS). However only limited literature is available and clinical studies involving these forefront devices are often small and non-randomized. Furthermore, there is a lack of consensus on free margins and cosmetic outcomes definitions. The objective of the present meta-analysis was to determine the crude clinical outcomes reported for the NWNI techniques on BCS. A literature search was performed of PubMed, Embase and Scopus databases up to February 2021 in order to select all prospective or retrospective clinical trials on pre-operative breast lesion localization done with NWNI devices. All studies were assessed following the PRISMA recommendations. Continuous outcomes were described in averages corrected for sample size, while binomial outcomes were described using the weighted average proportion. Twenty-seven studies with a total of 2103 procedures were identified. The technique is consolidated, showing for both reflectors' positioning and localization nearly the 100% rate of success. The re-excision and clear margins rates were 14% (95% CI, 11-17%) and 87% (80-92%), respectively. Overall, positive margins rates were 12% (8-17%). In studies that compared NWNI and wire localization techniques, positive margin rate is lower for the first techniques (12%, 6-22% vs 17%, 12-23%) and re-excision rate is slightly higher using the latter (13%, 9-19% vs 16%, 13-18%). Pre-operative NWNI techniques are effective in the localization of non-palpable breast lesions and are promising in obtaining clear (or negative) margins minimizing the need for re-excision and improving the cosmetic outcomes. Randomized trials are needed to confirm these findings.

BACKGROUND
Ewing sarcoma (ES) is a malignant neoplasm of neuroectodermal origin and is commonly observed in children and young adults. The musculoskeletal system is the main body system impacted and ES is rarely seen in the visceral organs particularly the adrenal gland.
AIM
To present a comprehensive review of primary adrenal ES, with emphasis on diagnosis, therapy and oncological outcomes.
METHODS
A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020. PubMed/ MEDLINE, EMBASE and Google Scholar bibliographic databases were searched to identify articles from 1989 to 2022 and included patients with ES/primitive neuroectodermal tumor (PNET) of the adrenal gland. PubMed, Google Scholar and EMBASE medical databases were searched, combining the terms "adrenal", "ES" and "PNET". Demographic, clinical, pathological and oncological data of patients were analyzed by SPSS version 29.0.
RESULTS
A total of 52 studies were included for review (47 case reports and 5 case series) with 66 patients reported to have primary adrenal ES. Mean age at diagnosis was 26.4 ± 15.4 years (37.9% males, 57.6% females, sex not reported in 3 cases). The most frequent complaint was abdominal/flank pain or discomfort (46.4%) followed by a palpable mass (25.0%), and the average duration of symptoms was 2.6 ± 3.1 mo. The imaging modality of choice was computed tomography scan (81.5%), followed by magnetic resonance imaging (20.4%). Preoperative staging revealed that 17 tumors (27.9%) were metastatic and 14 patients had inferior vena cava or renal vein neoplastic thrombus at initial diagnosis. Open adrenalectomy was performed in the majority of cases (80.0%), of which 27.9% required more extensive resection. Minimally invasive surgery was attempted in 8.2% of tumors. Complete surgical resection was achieved in 89.4% of the patients. Adjuvant therapy was administered to 32 patients, in the form of chemotherapy (62.5%), radiotherapy (3.1%) or combination (34.4%). Median overall survival was 15 mo and 24-mo overall survival was 40.5%. Median disease-free survival was 10 mo and 24-mo disease-free survival was 33.3%.
CONCLUSION
The significant progress in molecular biology and genetics of ES does not reflect on patient outcomes. ES remains an aggressive tumor with a poor prognosis and high mortality.
