Clear cell acanthoma (CCA) and squamous cell carcinoma (SCC) represent distinct entities within dermatological oncology, each posing unique diagnostic and therapeutic challenges. CCA is a rare, benign epidermal growth, often not associated with human papillomavirus (HPV) infection, whereas SCC, a more aggressive form of skin cancer, has been linked to both ultraviolet (UV) exposure and HPV. Understanding the co-occurrence of these conditions in a single patient can enhance diagnostic accuracy and therapeutic outcomes. We report a 64-year-old male who underwent an operation for a verruciform lesion in the right groin, which was diagnosed as HPV-positive CCA alongside keratinised SCC. A literature search across January 2024 revealed limited evidence directly linking HPV to CCA, suggesting a need for further investigation. The speculative association between HPV and CCA warrants deeper exploration, especially considering the potential for HPV to contribute to lesion development through indirect mechanisms. The coexistence of CCA and SCC in an elderly patient presents a unique clinical scenario. This emphasises the need for vigilant diagnosis and tailored treatment strategies, highlighting the gap in understanding the pathogenesis of CCA, particularly its potential association with HPV. Further research is crucial for elucidating the complex interactions governing these conditions and for developing targeted interventions.

UNASSIGNED: Negative Pressure Wound Therapy (NPWT) is a therapeutic technique of applying sub-atmospheric pressure to a wound to reduce inflammation, manage exudate, and promote the formation of granulation tissue. It aims to optimise the natural physiological processes of wound healing for more effective recovery, and NPWT has emerged as a promising alternative to traditional dressings.
UNASSIGNED: The protocol followed in the study was prospectively registered. Appropriate search terms and Boolean operators were used to search electronic databases for relevant articles. Screening of articles was performed, and data extraction was done. The effect measure was chosen according to the nature of the variable, and the effect model was chosen as per heterogeneity. Forest plot was used to give visual feedback.
UNASSIGNED: This study included 11 randomized controlled trials (13 publications) with a total of 1310 patients (1497 inguinal wounds). The NPWT group had lesser odds of developing surgical site infection (OR: 0.40; 95 % CI: 0.29-0.54; n = 1491; I2 = 20 %; p-value ≤0.00001) and lesser odds of needing surgical wound revision (OR: 0.48; 95 % CI: 0.26-0.91; n = 856; I2 = 0 %; p-value = 0.02) as compared to the normal dressing group. No significant difference was observed in duration of hospital stay, cost of care, wound healing time, or other complications.
UNASSIGNED: NPWT application in inguinal wounds significantly reduces the surgical site infection and the need for wound revision in patients who have undergone vascular surgery.

Flap-based reconstruction techniques have shown promise in preventing scar contractures and enhancing healing in fold areas by providing vascularized and thick tissue. We report a septic rupture of the superficial femoral artery treated with an arterial allograft and covered with a contralateral pedicled Deep Inferior Epigastric Artery Perforator (DIEP) flap. The patient presented favorable outcomes, including optimal healing at 8 months, with no functional limitation. A literature review also discusses alternative pedicled perforator flaps. These modern techniques present several advantages, including reliability, and can be of great interest in complex vascular surgery cases.

UNASSIGNED: The ideal surgical approach for the management of varicocele in children and adolescents remains controversial. Several techniques are available including artery- or lymphatic-sparing with optical magnification (via open inguinal or sub-inguinal approach), laparoscopic, antegrade and retrograde embolization/sclerotherapy.
UNASSIGNED: We aimed to appraise the clinical outcomes of these techniques in children and adolescents.
UNASSIGNED: A systematic review was conducted (1997-2023). Meta-analysis or proportional meta-analysis for non-comparative studies (Freeman-Tukey transformation) using the random effects model was conducted. Results are expressed as overall proportion % and 95% confidence interval (CI).
UNASSIGNED: We identified 1910 studies; 632 duplicates were removed, 1278 were screened, 203 were reviewed and 56 were included, with 12 reporting on 2 different techniques (total of 68 data sets). Optical magnification via inguinal approach (498 cases): recurrence 2.5% (0.6-5.6), hydrocele 1.6% (0.47-3.4), testicular atrophy 1% (0.3-2.0), complications 1.1% (0.2-2.6); optical magnification via sub-inguinal approach (592 cases): recurrence 2.1% (0.7-4.4), hydrocele 1.26% (0.5-2.3), testicular atrophy 0.5% (0.1-1.3), complications 4% (1.0-8.8). Laparoscopic with mass-ligation/division (1943 cases): recurrence 2.9% (1.5-4.6), hydrocele 11.4% (8.3-14.9); complications 1.5% (0.6-2.9); laparoscopic with lymphatic-sparing (974 cases): recurrence 2.4% (1.5-3.5), hydrocele 1.2% (0.45-3.36), complications 1.2% (0.05-3.9); laparoscopic with artery-sparing (228 cases): recurrence 6.6% (2.3-12.9), hydrocele 6.5% (2.6-12.0). Antegrade embolization/sclerotherapy (403 cases): recurrence 7.6% (5.2-10.4), hydrocele 0.8% (0.17-1.9), technical failure 0.6% (0.1-1.6), complications 4.0% (2.3-6.1); retrograde embolization/sclerotherapy (509 cases): recurrence 6.9% (4.6-9.5), hydrocele 0.8% (0.05-2.5), technical failure 10.2% (4.6-17.6), and complications 4.8% (1.0-11.2).
UNASSIGNED: The recurrence rate varies between 2.1% and 7.6% and is higher with the embolization/sclerotherapy techniques. Post-operative hydrocele rate varies between 0.8% and 11.4% and is higher with the laparoscopic mass-ligation/division technique. Testicular atrophy has not been reported with the laparoscopic and embolization/sclerotherapy techniques. The retrograde embolization technique is associated with 10% technical failure (inability to complete the procedure). The laparoscopic lymphatic-sparing technique is characterized by the lowest recurrence rate, incidence of hydrocele and other complications, and no reports of testicular atrophy.

Laparoscopic herniorrhaphy (LH) has become the treatment of choice in many centers for patients with inguinal hernia (IH). Our aim was to compare the morbidity outcomes of bilateral vs unilateral IH repair using the laparoscopic total extra-peritoneal (TEP) technique, to determine whether undertaking bilateral IH repair places patients at additional risk.
Manuscripts published up to the end of 2021 on PubMed/MEDLINE, EMBASE, Cochrane Library, Scopus, and Web of Science were searched. Patients (> 16 years) undergoing a primary elective unilateral or bilateral TEP operation, using the standard 3-port laparoscopic technique, were identified. Quality of evidence was assessed using the GRADE criteria. Meta-analysis was conducted where possible. Where this was not possible, vote counting was conducted using effect direction plots.
Eight observational studies, with a total of 18,153 patients were included. Operative time was significantly longer for bilateral operations. There was no significant difference in conversion to open, post-operative seroma, urinary retention, haematoma, and length of hospital stay. There was an increased rate of hernia recurrence in patients undergoing bilateral IH repair.
Although limited by the observational nature of the included studies, there is no conclusive evidence to suggest a differential burden of morbidity between unilateral and bilateral TEP IH repair. As all included papers are from observational studies only, evidence from all outcomes is at best very low quality. This manuscript thereby highlights a need for randomized controlled trials to be conducted in this area.

Groin surgical site infections (SSIs) after open revascularization can lead to devastating consequences in patients. As a result, prevention has been crucial in minimizing the rate of SSIs. This review aims to evaluate the current body of literature regarding prevention ,techniques including prophylactic flaps, incision technique, topical antibiotic use, closed-incision negative pressure wound therapy, and adhesive drapes.
This review was conducted and reported in accordance with the PRISMA statement. A systematic review was conducted using the Google Scholar, PubMed, and Cochrane Review databases regarding the five prevention topics. The authors identified 1371 potential studies with 33 studies selected and analyzed after systematic review regarding the five preventative topics.
The primary outcome of interest was how the rate of SSI was affected with each preventative technique. As a result, the recommendations are as follows. We suggest prophylactic flaps be considered in high-risk surgical patients undergoing open arterial exposure of the groin (Grade 2C). We suggest consideration of transverse incisions for open arterial exposure of the groin as a means of SSI prevention (Grade 2C). Given the lack of data regarding topical antibiotics no recommendation can be made regarding its use, we suggest closed-incision negative pressure wound therapy be used in groin surgical incisions at high risk for SSI (Grade 2B). Given the paucity of data regarding adhesive drapes, such as Ioban, no recommendation can be made regarding its use.
This review highlights the effects of various preventative techniques and their potential benefit in the prevention of SSI in the groin. However, there is a glaring deficit in the available data, emphasizing the need for additional robust studies to better delineate their effectiveness and implementation into surgical practice. The use of endovascular techniques continues to increase, thus limiting the number of open arterial procedures and the potential for further studies to be conducted. To provide the high-quality studies needed to better evaluate these prevention techniques, large multi-institutional collaboration will likely be necessary to provide the appropriate number of patients to evaluate true effectiveness.

To realize a systematic review to evaluate groin hernia surgery for adults in sub-Saharan Africa.
We conducted a systematic review and meta-analysis, the primary objective of which was to determine the surgical techniques used for unilateral groin hernia surgery in sub-Saharan Africa. Studies published in the last 20 years were considered. A meta-analysis estimated the pooled prevalence with 95% confidence interval (CI) of mortality, chronic pain and recurrence. A subgroup analysis compared the rate of complications between complicated or uncomplicated hernia.
We included 113 articles. The most used technique was Bassini in 40.1%, followed by Lichtenstein in 29.9% and Shouldice in 12.6%. The overall mortality rate was 0.6% (95% CI 0.4-0.9). The pooled recurrence rate was 1.4% (95% CI 1.05-1.9). The pooled rate of chronic pain was 2.7% (95% CI 1.9-3.7). We found that mortality rate for complicated hernias (6.4%) was higher compared to uncomplicated hernias (0.2%). This difference was statistically significant [p ≤ 0.001; OR = 47.7; 95 CI (27.2-83.47)].
This review showed that pure tissue repairs are the most used techniques with Bassini and Shouldice as leading procedures. The post-operative rates of recurrence and chronic pain are low. However, there is a high heterogeneity between studies than can underestimate these pooled prevalences. The consultation at complication stage remains frequent and associated with a higher mortality. Futures studies should focus on improving the quality of studies in terms of design and follow-up to increase the degree of evidence.

Surgical residents routinely participate in open and laparoscopic groin hernia repairs. The increasing popularity of robot-assisted groin hernia repair could lead to an educational loss for residents. We aimed to explore the involvement of surgical specialists and surgical residents, i.e., non-specialists, in robot-assisted groin hernia repair. The scoping review was reported according to PRISMA-ScR guideline. A protocol was uploaded at Open Science Framework, and a systematic search was conducted in four databases: PubMed, EMBASE, Cochrane CENTRAL, and Web of Science. Included studies had to report on robot-assisted groin hernia repairs. Data charting was conducted in duplicate. Of the 67 included studies, 85% of the studies described that the robot-assisted groin hernia repair was performed by a surgical specialist. The rest of the studies had no description of the primary operating surgeon. Only 13% of the included studies reported that a resident attended the robot-assisted groin hernia repair. Thus, robot-assisted groin hernia repair was mainly performed by surgical specialists, and robot-assisted groin hernia repair therefore seems to be underutilized to educate surgical residents.

To investigate the contemporary rates of 30-day complications after surgery for penile cancer and to discuss the currently used preventative and therapeutic practices aimed at mitigation of these postoperative adverse events.
A systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed, and studies reporting on the contemporary rates, nature, or management of acute complications following primary penile surgery or inguinal lymph node dissection for penile cancer were abstracted. Medline (PubMed) and EMBASE libraries were used to retrieve the articles published between January 1984 and December 2021 (n = 170 articles). Ultimately, 38 articles were included. The primary outcome of interest was 30-day (acute) postoperative complications, stratified by those associated with treatment of the primary penile lesion and those with inguinal lymph node dissection. Risk of bias assessment was undertaken. Special attention was paid to studies reporting management strategies for these complications.
This comprehensive review revealed that the quality of existing studies reporting on complications is poor and the risk of bias is high. Within these studies, the rates of acute complications following primary penile surgery and inguinal lymph node dissection ranged between 0% and 29.4% and 6% and 90%, respectively. More than 50% of these complications were wound related. Over the past two decades, several studies have reported on improved surgical techniques and protocolized postsurgical care pathways. Although the newer techniques have been associated with improved outcomes, the absolute rates of complications have remained high even in the most contemporary series. Therefore, there is an urgent need for health care providers and stakeholders to reach consensus regarding preoperative workup and medical optimization goals, stage appropriate therapies, and postoperative care pathways, as has been done for other malignancies associated with high morbidity.
Penile cancer is a disease of the elderly, and surgical management of the primary lesion or the groins is associated with a high rate of complications. Most complications are wound related. Meticulous surgical technique and careful postoperative monitoring with early intervention are keys to mitigating surgery-related morbidity. However, equally important is dissemination and adoption of these principles by all health care workers universally.

BACKGROUND: In the past two decades, laparoscopy has provided an alternative approach to inguinal hernia repair. The aim of this review is to carry out a retrospective systematic analysis of articles dealing with laparoscopic hernia repair in children and a review of the Maltese experience.
METHODS: Data was obtained from publications from 2002 to 2019. The endpoints include: patient demographics, clinical presentations, laparoscopic tools, ports, suture used, technical remarks, length of surgery, hospital stay, complications and follow-up.
RESULTS: 32 studies were included with a total of 10,183 patients. Most articles documented the use of 1 port. Length of surgery ranged from an average of 10 to 138 min. Ipsilateral recurrences were reported in 0.83% of cases, while 0.17% required conversion to open.
UNASSIGNED: In our centre, a population of 514, 564 is covered (16% under the age of 18). A total of 14 cases of laparoscopic inguinal hernia repair were carried out from August 2018 till October 2020. The neonatal laparoscopic set-up involves a 30⁰ laparoscope, inserted via a 5 mm umbilical port, with 2 stab incisions allowing the use of 3 mm devices. Intra-corporeal purse string suture technique is used. The length of surgery ranged from 1 hr to 2 hr 30 min. There was 1 case of ipsilateral recurrence and another requiring conversion to open surgery.
CONCLUSIONS: Laparoscopic inguinal hernia repair in children is a versatile and safe procedure that can be carried out with minimal complications and low reoperation rates.
METHODS: Level IV.
