RESUMEN
BACKGROUND: The anatomic variants of the intercostobrachial nerve (ICBN) represent a potential risk of injuries during surgical procedure such as axillary lymph node dissection and sentinel lymph node biopsy in breast cancer and melanoma patients. The aim of this systematic review and meta-analysis was to investigate the different origins and branching patterns of the intercostobrachial nerve also providing an analysis of the prevalence, through the analysis of the literature available up to September 2023. MATERIALS AND METHODS: The protocol for this study was registered on PROSPERO (ID: CRD42023447932), an international prospective database for reviews. The PRISMA guideline was respected throughout the meta-analysis. A systematic literature search was performed using PubMed, Scopus and Web of Science. A search was performed in grey literature through google. RESULTS: We included a total of 23 articles (1,883 patients). The prevalence of the ICBN in the axillae was 98.94%. No significant differences in prevalence were observed during the analysis of geographic subgroups or by study type (cadaveric dissections and in intraoperative dissections). Only five studies of the 23 studies reported prevalence of less than 100%. Overall, the PPE was 99.2% with 95% Cis of 98.5% and 99.7%. As expected from the near constant variance estimates, the heterogeneity was low, I2 = 44.3% (95% CI 8.9%-65.9%), Q = 39.48, p = .012. When disaggregated by evaluation type, the difference in PPEs between evaluation types was negligible. For cadaveric dissection, the PPE was 99.7% (95% CI 99.1%-100.0%) compared to 99.0% (95% CI 98.1%-99.7%). CONCLUSIONS: The prevalence of ICBN variants was very high. The dissection of the ICBN during axillary lymph-node harvesting, increases the risk of sensory disturbance. The preservation of the ICBN does not modify the oncological radicality in axillary dissection for patients with cutaneous metastatic melanoma or breast cancer. Therefore, we recommend to operate on these patients in high volume center to reduce post-procedural pain and paresthesia associated with a lack of ICBN variants recognition.

BACKGROUND: Skin metastases are an important co-morbidity in melanoma. Despite broad adoption, electrochemotherapy implementation is hindered by a lack of treatment indications, uncertainty regarding procedural aspects, and the absence of quality indicators. An expert consensus may harmonize the approach among centres and facilitate comparison with other therapies. METHODS: An interdisciplinary panel was recruited for a three-round e-Delphi survey. A literature-based 113-item questionnaire was proposed to 160 professionals from 53 European centres. Participants rated each item for relevance and degree of agreement on a five-point Likert scale, and received anonymous controlled feedback to allow revision. The items that reached concordant agreement in two successive iterations were included in the final consensus list. In the third round, quality indicator benchmarks were defined using a real-time Delphi method. RESULTS: The initial working group included 122 respondents, of whom 100 (82 per cent) completed the first round, thus qualifying for inclusion in the expert panel (49 surgeons, 29 dermatologists, 15 medical oncologists, three radiotherapists, two nurse specialists, two clinician scientists). The completion rate was 97 per cent (97 of 100) and 93 per cent (90 of 97) in the second and third rounds respectively. The final consensus list included 54 statements with benchmarks (treatment indications, (37); procedural aspects, (1); quality indicators, (16)). CONCLUSION: An expert panel achieved consensus on the use of electrochemotherapy in melanoma, with a core set of statements providing general direction to electrochemotherapy users to refine indications, align clinical practices, and promote quality assurance programmes and local audits. The residual controversial topics set future research priorities to improve patient care.
Electrochemotherapy is an effective locoregional therapy for skin metastases from melanoma, a problem faced by almost half of patients with metastatic disease. The lack of comparative studies and the heterogeneity of its clinical application among centres make it challenging to support consistent, evidence-based recommendations. To address this unmet need, a three-round online survey was conducted to establish a consensus on treatment indications, standard operating procedures, and quality indicators. In the survey, a panel of 100 European melanoma experts agreed on 56 statements that can be used to improve patient selection, homogenize treatment application, and monitor outcomes.

Cutaneous immune-related adverse events (irAEs) occur in more than one-third of patients treated with immune checkpoint inhibitors; they are often the first clinical manifestation, although they may occur months after initiation of therapy. We noticed that our patients usually have these cutaneous AEs on photodamaged skin. In fact, out of 19 patients being treated for metastatic melanoma, 8 (42%), all of whom had significant cutaneous actinic damage, developed cutaneous irAEs earlier and in a more serious form than those without such damage. Thus, we gave a high oral dose of nicotinamide (500 mg twice daily) to the patients with metastatic melanoma who had photodamaged skin, and continued this for the entire duration of the immunotherapy. The appearance of the first signs of cutaneous irAEs was 180 days after starting therapy in nicotinamide-treated patients, compared with 65 days for patients not treated with nicotinamide.

OBJECTIVE: This study aimed to evaluate the incidence of chronic groin pain (primary outcome) and alterations of sensitivity (secondary outcome) after Lichtenstein inguinal hernia repair, comparing neurectomy with ilioinguinal nerve preservation surgery. The exact cause of chronic groin postoperative pain after mesh inguinal hernia repair is usually unclear. Section of the ilioinguinal nerve (neurectomy) may reduce postoperative chronic pain. METHODS: We followed PRISMA guidelines to identify randomized studies reporting comparative outcomes of neurectomy versus ilioinguinal nerve preservation surgery during Lichtenstein hernia repairs. Studies were identified by searching in PubMed, Scopus, and Web of Science from April 2020. The protocol for this systematic review and meta-analysis was submitted and accepted from PROSPERO: CRD420201610. RESULTS: In this systematic review and meta-analysis, 16 RCTs were included and 1550 patients were evaluated: 756 patients underwent neurectomy (neurectomy group) vs 794 patients underwent ilioinguinal nerve preservation surgery (nerve preservation group). All included studies analyzed Lichtenstein hernia repair. The majority of the new studies and data comes from a relatively narrow geographic region; other bias of this meta-analysis is the suitability of pooling data for many of these studies. A statistically significant percentage of patients with prosthetic inguinal hernia repair had reduced groin pain at 6 months after surgery at 8.94% (38/425) in the neurectomy group versus 25.11% (113/450) in the nerve preservation group [relative risk (RR) 0.39, 95% confidence interval (CI) 0.28-0.54; Z = 5.60 (P < 0.00001)]. Neurectomy did not significantly increase the groin paresthesia 6 months after surgery at 8.5% (30/353) in the neurectomy group versus 4.5% (17/373) in the nerve preservation group [RR 1.62, 95% CI 0.94-2.80; Z = 1.74 (P = 0.08)]. At 12 months after surgery, there is no advantage of neurectomy over chronic groin pain; no significant differences were found in the 12-month postoperative groin pain rate at 9% (9/100) in the neurectomy group versus 17.85% (20/112) in the inguinal nerve preservation group [RR 0.50, 95% CI 0.24-1.05; Z = 1.83 (P = 0.07)]. One study (115 patients) reported data about paresthesia at 12 months after surgery (7.27%, 4/55 in neurectomy group vs. 5%, 3/60 in nerve preservation group) and results were not significantly different between the two groups [RR 1.45, 95% CI 0.34, 6.21;Z = 0.51 (P = 0.61)]. The subgroup analysis of the studies that identified the IIN showed a significant reduction of the 6th month evaluation of pain in both groups and confirmed the same trend in favor of neurectomy reported in the previous overall analysis: statistically significant reduction of pain 6 months after surgery at 3.79% (6/158) in the neurectomy group versus 14.6% (26/178) in the nerve preservation group [RR 0.28, 95% CI 0.13-0.63; Z = 3.10 (P = 0.002)]. CONCLUSION: Ilioinguinal nerve identification in Lichtenstein inguinal hernia repair is the fundamental step to reduce or avoid postoperative pain. Prophylactic ilioinguinal nerve neurectomy seems to offer some advantages concerning pain in the first 6th month postoperative period, although it might be possible that the small number of cases contributed to the insignificancy regarding paresthesia and hypoesthesia. Nowadays, prudent surgeons should discuss with patients and their families the uncertain benefits and the potential risks of neurectomy before performing the hernioplasty.

Electrochemotherapy (ECT) is a well-known nonconventional skin cancer ablative method that was shown to be safe and effective for treating both locoregional disease spreading and disseminated cutaneous and subcutaneous lesions from different types of cancer. The most common medications used are bleomycin and cisplatin. In the last years many studies were performed on ECT, lead it to be a valid therapeutic option in many international guidelines. Nevertheless, there are still no clear indications regarding timing of its use. The main aim of this study was first to assess the safety and effectiveness of intralesional cisplatin ECT for treating different types of nonmelanoma skin cancer in a group of eligible patients. The second endpoint was to assess patients' tolerability and symptoms improvement through the treatment. A single-center prospective study was performed. Patients with squamous cell carcinoma, basal cell carcinoma, or skin metastases were selected during 1 month. The ideal setting was the presence of two or three lesions with a maximum diameter of 2 cm. Both primary, recurrent, and metastatic lesions were included. Before and 8 weeks after treatment, all patients were evaluated to assess the number, measurement, and anatomical site of skin lesions using photography and metric notation. The medical device for membrane electroporation was the CLINIPORATOR EPS02 model. The cisplatin concentration was at least 1 mg/mL. The dose for each single lesion was calculated based on its volume, as is the standard procedure for ECT. Local or systemic adverse events and changes in symptoms were evaluated with a questionnaire based on a visual analog scale that was administrated before and after ECT. Eight patients with a total of 18 lesions underwent the procedure (six men and two women). Four out of eight (50%) patients had a complete response to the treatment. However, all eight patients had an overall tumor response (100%), experiencing an improvement in symptoms including less pain and bleeding from the tumor. Our study clearly show that ECT with intralesional cisplatin is a valuable and safety procedure for nonmelanoma skin cancer and cutaneous tumor metastasis. ECT with cisplatin was able to achieve a good local disease control leading to complete response in an half of cases. The results were stable after 1 year of follow-up. The outer ear area displayed a really good response, due to both ear's anatomical configuration and intralesional cisplatin pharmacological characteristics.

Metastatic skin lesions of gastric cancers usually appear as nonspecific, firm, and hyperpigmented nodules. However, they occasionally present as unusual skin manifestations that mimic other skin disorders. We describe a case of multiple cutaneous metastases from gastric cancer resembling sebaceous cysts with a synchronous melanoma, in a patient after fluoropyrimidine-based systemic chemotherapy. Melanoma occurring as a second cancer has been recognized in patients having undergone previous chemotherapy or radiation for another cancer. We can assume that the capecitabine-based chemotherapy may have played a role in the development of the melanocytic neoplasm. Our observation adds extra evidence to the link between fluoropyrimidine-based immunosuppression and the induction of melanocytes' proliferation and transformation. For these reasons, it is advisable to require dermatological checkups for patients undergoing chemotherapy treatments in order to identify suspicious melanocytic lesions as soon as possible.

BACKGROUND: Three-dimensional (3D) vision technology has recently been validated for the improvement of surgical skills in a simulated setting. Clinical studies on specific operations have been published in the field of general, urologic, and gynecologic laparoscopic surgery. We hypothesized that 3D vision laparoscopic right colectomy has better intra and short-term postoperative outcomes than two-dimensional (2D) vision. AIM: The outcomes of this review and meta-analysis were to compare the 3D vision and the 2D vision laparoscopic right colectomy. METHODS: A systematic search of the literature was performed on Pubmed, WOS, Google Scholar, and Scopus databases (Prospero reg. nr. 42016047704) for comparative studies between 2D and 3D laparoscopic right colectomy. Primary endpoints were safety issues and secondarily patients' related and surgeons' comfort outcomes. Meta-analyses, when possible, were conducted with a random-effects model. RESULTS: Two retrospective comparative studies (for a total of 56 patients in the 2D arm and 52 patients for the 3D arm) were selected out of 680 screened records. Methodological quality was fair. Three-dimensional laparoscopic right colectomy has similar safety and secondary outcomes when compared to 2D, with not statistically significant shorter operating times (mean difference 11.81 min). The results are comparable also for anastomosis leakage. The results for other outcomes were not aggregated for heterogeneity. CONCLUSIONS: 3D laparoscopic right colectomy shows equivalent patients' outcomes compared to 2D operation, but the scarce clinical data and the potential amelioration of surgeons' skills, especially on difficult intracorporeal tasks like suturing, suggest the publication of further trials.

BACKGROUND: Lichenoid keratosis is a benign cutaneous lesion exhibiting many clinical faces and different dermoscopic features. OBJECTIVE: This study aims to determine the pattern of different clinical subtypes of lichenoid keratosis and to establish whether there is any correlation between the clinical variants of lichenoid keratosis and their dermoscopic appearance. METHODS: We retrospectively analyzed the medical records and clinical database of patients who had received a histological diagnosis of lichenoid keratosis. Based on the literature review and the clinical-dermoscopic features of lichenoid keratosis, we divided the lesions into 6 clinical subtypes to evaluate potential correlations between clinical and dermoscopic features in all subtypes. RESULTS: Fifty-one lesions were included in this clinical study. Preoperatively, only 1.9% of cases were clinically diagnosed as lichenoid keratosis, and the most common misdiagnosis was basal cell carcinoma (52.9%). We identified 6 subtypes of lichenoid keratosis and their corresponding dermoscopic features and clues. CONCLUSION: Since lichenoid keratosis has no pathognomonic dermoscopic clues and it is commonly misdiagnosed as malignant skin neoplasms, such as basal cell carcinoma and melanoma, improving the knowledge of both clinical and dermoscopic variability of lichenoid keratosis may help dermatologists to reduce unnecessary surgery and to reduce health care spending.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is caused by incomplete obliteration of the vitelline duct during intrauterine life. MD affects less than 2% of the population. In most cases, MD is asymptomatic and the estimated average complication risk of MD carriers, which is inversely proportional to age, ranges between 2% and 4%. The most common MD-related complications are gastrointestinal bleeding, intestinal obstruction and acute phlogosis. Excision is mandatory in the case of symptomatic diverticula regardless of age, while surgical treatment for asymptomatic diverticula remains controversial. According to the majority of studies, the incidental finding of MD in children is an indication for surgical resection, while the management of adults is not yet unanimous. In this case report, we describe the prophylactic resection of an incidentally detected MD, which led to the removal of an occult mucosal carcinoid tumor. In literature, the association of MD and carcinoid tumor is reported as a rare finding. Even though the strategy for adult patients of an incidental finding of MD during surgery performed for other reasons divides the experts, we recommend prophylactic excision in order to avoid any further risk.

Vulvar melanoma is considered rare, but it is the second most frequent vulvar neoplasm; 2% of melanomas in women arise in the vulvar area. It is important to highlight how the characteristics of vulvar melanoma differentiate it from classic cutaneous melanoma. Vulvar melanoma has different risk factors and clinical and dermoscopic characteristics; moreover, it has a higher recurrence rate and a greater likelihood of multifocality. Here, we present a case of a 44-year-old patient with two primary vulvar melanomas located on opposite sides of her vulva. The lesions were both flat, but they had distinct clinical and dermoscopic appearances. Melanoma of the genital tract is likely the result of a multifocal disorder of the melanocytes within the mucosa that inhabit the perineal squamous epithelium. The risk factors of vulvar melanoma differ from those of classical cutaneous melanomas. Vulvar melanoma occurs in an area shielded from ultraviolet radiation; the primary risk factors include chronic inflammatory disease, genetic susceptibility, irritant agents and viral infections. This case study reveals how a close examination of the genital area is important and how dermoscopy can aid in the differential diagnosis of vulvar lesions. Inspections of the genital area should be particularly thorough if a melanoma is detected there, given the higher risk of multifocality in that part of the body.
RESUMEN
BACKGROUND: Bariatric surgery is an effective treatment to obtain weight loss in severely obese patients. The feasibility and safety of bariatric robotic surgery is the topic of this review. METHODS: A search was performed on PubMed, Cochrane Central Register of Controlled Trials, BioMed Central, and Web of Science. RESULTS: Twenty-two studies were included. Anastomotic leak rate was 8.51% in biliopancreatic diversion. 30-day reoperation rate was 1.14% in Roux-en-Y gastric bypass and 1.16% in sleeve gastrectomy. Major complication rate in Roux-en-Y gastric bypass resulted higher than in sleeve gastrectomy ( 4,26% vs. 1,2%). The mean hospital stay was longer in Roux-en-Y gastric bypass (range 2.6-7.4 days). CONCLUSIONS: The major limitation of our analysis is due to the small number and the low quality of the studies, the small sample size, heterogeneity of the enrolled patients and the lack of data from metabolic and bariatric outcomes. Despite the use of the robot, the majority of these cases are completed with stapled anastomosis. The assumption that robotic surgery is superior in complex cases is not supported by the available present evidence. The major strength of the robotic surgery is strongly facilitating some of the surgical steps (gastro-jejunostomy and jejunojejunostomy anastomosis in the robotic Roux-en-Y gastric bypass or the vertical gastric resection in the robotic sleeve gastrectomy).

PURPOSE: To improve the diagnostic accuracy and optimal management of pediatric melanomas. METHODS: We conducted a retrospective descriptive, multicenter study of the epidemiological, clinical, and dermoscopic characteristics of histopathologically proven melanomas diagnosed in patients less than 18 years old. Data on sociodemographic variables, clinical and dermoscopic characteristics, histopathology, local extension, therapy and follow-up, lymph node staging, and outcome were collected from the databases of three Italian dermatology units. We performed a clinical evaluation of the morphological characteristics of each assessed melanoma, using both classic ABCDE criteria and the modified ABCDE algorithm for pediatric melanoma to evaluate which of the two algorithms best suited our series. RESULTS: The study population consisted of 39 patients with a histologically confirmed diagnosis of pediatric melanoma. Comparing classic ABCDE criteria with the modified ABCDE algorithm for pediatric melanomas, the modified pediatric ABCDE algorithm was less sensitive than the conventional criteria. Dermoscopically, the most frequent finding was the presence of irregular streaks/pseudopods (74.4%). When evaluating the total number of different suspicious dermoscopy criteria per lesion, 64.1% of the lesion assessments recognized two dermoscopic characteristics, 20.5% identified three, and 15.4% documented four or more assessments. CONCLUSIONS: Contrary to what has always been described in the literature, from a clinical point of view, about 95% of our cases presented in a pigmented and non-amelanotic form, and these data must be underlined in the various prevention campaigns where pediatric melanoma is currently associated with a more frequently amelanotic form. All the pediatric melanomas analyzed presented at least two dermoscopic criteria of melanoma, suggesting that this could be a key for the dermoscopic diagnosis of suspected pediatric melanoma, making it possible to reach an early diagnosis even in this age group.
RESUMEN
BACKGROUND: BRAF inhibitors such as vemurafenib are a new family of biological drugs, recently available to treat metastatic malignant melanoma. METHODS: We present the case of a 38-year-old man affected by metastatic melanoma who had been under treatment with vemurafenib for a few days. The patient suffered from sudden onset of abdominal pain due to intra-abdominal hemorrhage with profuse hemoperitoneum. An emergency abdominal sonography confirmed the clinical suspicion of a splenic rupture. RESULTS: The intraoperative finding was hemoperitoneum due to splenic two-step rupture and splenectomy was therefore performed. Histopathology confirmed splenic hematoma and capsule laceration, in the absence of metastasis. CONCLUSIONS: This report describes the occurrence of a previously unreported adverse event in a patient with stage IV melanoma receiving vemurafenib.

In anterior resection of rectum, the section level of inferior mesenteric artery is still subject of controversy between the advocates of high and low tie. The low tie is the division and ligation to the branching of the left colic artery and the high tie is the division and ligation at its origin at the aorta. We intend to assess current scientific evidence in literature and to establish the differences comparing technique, anatomy and physiology. The aim of this protocol is to achieve a meta-analysis that tests safety and feasibility of the two procedures with several types of outcome measures.

Primitive Gastrointestinal Lymphomas (PGIL) are uncommon tumours, although time-trend analyses have demonstrated an increase. The role of surgery in the management of lymphoproliferative diseases has changed over the past 40 years. Nowadays their management is centred on systemic treatments as chemo-/radiotherapy. Surgery is restricted to very selected indications, always discussed in a multidisciplinary setting. The aim of this systematic review is to evaluate the actual role of surgery in the treatment of PGIL. A systematic review of literature was conducted according to the recommendations of The Cochrane Collaboration. Main outcomes analysed were overall survival (OS) and disease free survival (DFS). There are currently 1 RCT and 4 non-randomised prospective controlled studies comparing surgical versus medical treatment for PGIL. Seven hundred and one patients were analysed, divided into two groups: 318 who underwent to surgery alone or associated with chemotherapy and/or radiotherapy (surgical group) versus 383 who were treated with chemotherapy and/or radiotherapy (medical group). Despite the OS at 10 years between surgical and medical groups did not show relevant differences, the DFS was significantly better in the medical group (P=0.00001). Accordingly a trend was noticed in the recurrence rate, which was lower in the medical group (6.06 vs. 8.57%); and an higher mortality was revealed in the surgical group (4.51% vs. 1.50%).The chemotherapy confirms its primary role in the management of PGIL as part of systemic treatment in the medical group. Surgery remains the treatment of choice in case of PGIL acutely complicated, although there is no evidence in literature regarding the utility of preventive surgery.

Melanoma can involve the gastrointestinal apparatus as both primary and metastatic lesions. Primary anorectal mucosal melanoma (ARMM) and metastatic gastric melanoma are rare entities and usually resulted in a poor prognosis. We presented a case of a 61-year-old man who after the complete excision of an ARMM developed a gastric metastasis after almost three years form the complete tumour excision. Upon esophagogastroduodenoscopy, a giant ulcered mass resulted in melanoma metastasis. The patient underwent a near-total gastrectomy. After five months of follow-up, the patient is disease-free. The incidence of ARMMs is increasing, highlighting the necessity of new prevention and treatment strategies in order to achieve a better prognosis for these patients. There are no known risk factor for ARMMs but surgery, together with the combination of anti-CTLA-4 and anti-PD-1 antibodies, are promising therapeutic options. Early and aggressive treatments are required, together with a strict multidisciplinary approach.
