RESUMO
BACKGROUND: The Evaluation of Groin Lymphadenectomy Extent for Melanoma (EAGLE FM) study sought to address the question of whether to perform inguinal (IL) or ilio-inguinal lymphadenectomy (I-IL) for patients with inguinal nodal metastatic melanoma who have no clinical or imaging evidence of pelvic disease. Primary outcome measure was disease-free survival at 5 years, and secondary endpoints included lymphoedema. METHODS: EAGLE FM was designed to recruit 634 patients but closed with 88 patients randomised because of slow recruitment and changes in melanoma management. Lymphoedema assessments occurred preoperatively and at 6, 12, 18, and 24 months postoperatively. Lymphoedema was defined as Inter-Limb Volume Difference (ILVD) > 10%, Lymphoedema Index (L-Dex®) > 10 or change of L-Dex® > 10 from baseline. RESULTS: Prevalence of leg lymphoedema between the two groups was similar but numerically higher for I-IL at all time points in the first 24 months of follow-up; highest at 6 months (45.9% IL [CI 29.9-62.0%], 54.1% I-IL [CI 38.0-70.1%]) and lowest at 18 months (18.8% IL [CI 5.2-32.3%], 41.4% I-IL [CI 23.5-59.3%]). Median ILVD at 24 months for those affected by lymphoedema was 14.5% (IQR 10.6-18.7%) and L-Dex® was 12.6 (IQR 9.0-17.2). There was not enough statistical evidence to support associations between lymphoedema and extent of surgery, radiotherapy, or wound infection. CONCLUSIONS: Despite a trend for patients who had I-IL to have greater lymphoedema prevalence than IL in the first 24 months after surgery, our study's small sample did not have the statistical evidence to support an overall difference between the surgical groups.

OBJECTIVE: To assess clinical outcomes of inguinal lymph node surgical resection compared to primary groin radiotherapy for locally advanced, surgically unresectable vulvar cancer. METHODS: All patients treated with radiation for vulvar cancer were identified between Jan 1, 2000 - Dec 31, 2020 at 2 academic centres. Inclusion criteria were those treated with curative intent primary radiotherapy +/- chemotherapy, tumors >4 cm, and surgically unresectable squamous cell vulvar carcinoma. Groin recurrence-free survival (RFS) was compared for groin surgery and primary groin radiotherapy using the Kaplan Meier method and log rank test. Groin failures are described by treatment modality, radiation dose and lymph node size. RESULTS: Of 476 patients treated with radiation for vulvar cancer, 112 patients (23.5%) met inclusion and exclusion criteria. The median (95% CI) follow up was 1.9 (1.4-2.5) years. Complete clinical response was significantly higher (80.0%) in patients with surgical groin resection compared to patients treated with primary groin radiotherapy (58.2%) (p = 0.04). On multivariable analysis, after adjusting for clinical and/or radiologically abnormal lymph nodes (p = 0.67), surgical groin resection was significantly associated with lower groin recurrence (HR 0.2 (95%CI 0.05-0.92), p = 0.04). The 3-year groin recurrence-free survival (RFS) was significantly higher at 94.4% (87.1-100) in patients with surgical groin resection compared to 79.2% (69.1-90.9) in patients treated with primary radiation (p = 0.02). CONCLUSIONS: In locally advanced squamous cell vulvar cancer, surgical groin management improves groin RFS compared to radiotherapy alone.

AIM: The significance of lymphadenectomy and its indications in patients with inguinal lymph node metastasis (ILNM) of anorectal adenocarcinoma is unclear. This study aimed to clarify the surgical outcomes and prognostic factors of inguinal lymphadenectomy for ILNM. METHOD: This study included patients who underwent surgical resection for ILNM of rectal or anal canal adenocarcinoma with pathologically positive metastases between 1997 and 2011 at 20 participating centres in the Study Group for Inguinal Lymph Node Metastasis from Colorectal Cancer organized by the Japanese Society for Cancer of the Colon and Rectum. Clinicopathological characteristics and short- and long-term postoperative outcomes were retrospectively analysed. RESULTS: In total, 107 patients were included. The primary tumour was in the rectum in 57 patients (53.3%) and in the anal canal in 50 (46.7%). The median number of ILNMs was 2.34. Postoperative complications of Clavien-Dindo Grade III or higher were observed in five patients. The 5-year overall survival rate was 38.8%. Multivariate analysis identified undifferentiated histological type (P < 0.001), pathological venous invasion (P = 0.01) and pathological primary tumour depth T0-2 (P = 0.01) as independent prognostic factors for poor overall survival. CONCLUSION: The 5-year overall survival after inguinal lymph node dissection was acceptable, and it warrants consideration in more patients. Further larger-scale studies are needed in order to clarify the surgical indications.

BACKGROUND: Penile carcinoma is an uncommon cancer that develops in the penis tissue. The standard surgical method to manage regional lymph nodes after local excision is radical inguinal lymphadenectomy, but it has a high rate of complications. The objective of this retrospective study was to compare the long-term outcomes of endoscopic inguinal lymphadenectomy and open inguinal lymphadenectomy in patients with penile carcinoma. METHODS: The study included patients diagnosed with penile carcinoma who underwent open inguinal lymphadenectomy (n = 23) or endoscopic inguinal lymphadenectomy (n = 27) at a single hospital between January 2013 and January 2021. Operation time, blood loss, drainage, hospital stay, postoperative complications, and survival rates were assessed and compared between the two groups. RESULTS: The two groups were comparable in terms of age, tumor size and stage, inguinal lymph nodes, and follow-up. The endoscopic group had significantly lower blood loss (27.1 ± 1.5 ml vs 55.0 ± 2.7 ml, P < 0.05), shorter drainage time and hospital stay (4.7 ± 1.1 days vs 8.1 ± 2.2 days, and 13.4 ± 1.0 days vs 19 ± 2.0 days, respectively, P < 0.05), and longer operation time compared to the open group (82.2 ± 4.3 min in endoscopic group vs 53.1 ± 2.2 min in open group, P < 0.05). There were significant differences in the incidence of incisional infection, necrosis, and lymphorrhagia in both groups (4 vs 0, 4 vs 0, and 2 vs 0, respectively, P < 0.05). The inguinal lymph node harvested was comparable between the two groups. The mean follow-up time was similar for both groups (60.4 ± 7.7 m vs 59.8 ± 7.3 m), and the recurrence mortality rates were not significantly different. CONCLUSIONS: The study shows that both open and endoscopic methods work well for controlling penile carcinoma in the long term. But the endoscopic approach is better because it has fewer severe complications. So, the choice of surgery method might depend on factors like the surgeon's experience, what they like, and what resources are available.

PURPOSE: Clarify the composition of the Posterior wall of the Inguinal Canal(PWIC), the location and composition of the Transverse Fascia(TF), and the tissue origin of the Cremaster(C) by observing the anatomy of the inguinal region of the cadaver. METHODS: 30 cadavers were dissected to observe the alignment of the muscles and fascia of the inguinal canal and the anterior peritoneal space. the anatomical levels of the posterior wall of the inguinal canal and the alignment of the Spermatic Cord(SC) were observed. RESULTS: (1) The posterior wall of the inguinal canal was white, bright, and tough tendon membrane-like tissue; (2) the transverse fascia was a thin fascial tissue with only one layer of membranous structure located in the abdominal wall under the abdominal wall on the side of the blood vessels of the peritoneal cavity; (3) the internal oblique muscle and its tendon membrane, and the transversus abdominis muscle and its tendon membrane extended on the surface of the spermatic cord, and fused and continued to the cremaster on the surface of the spermatic cord. CONCLUSIONS: 1. PWIC is mainly composed of Internal oblique muscle of abdomen (IOMA), Aponeurosis of internal oblique muscle of abdomen (AIOMA), Transverse abdominal muscle (TAM), and Transverse abdominal aponeurosis(TAA) as the following four types: (1) TAM and AIOMA fused to form a tendinous layer; (2) IOMA and TAM form the posterior wall of the muscle in the PWIC; (3) IOMA and AIOMA continue in the PWIC; 4) TAM and TAA continue in the PWIC. 2.TF is a thin fascial tissue with only one layer of membrane structure, TF is not involved in the composition of PWIC, so this fascia has nothing to do with resisting the occurrence of inguinal hernia. 3. The spermatic cord that travels in the inguinal canal is fixed to the lower wall of the inguinal canal by the tendon membrane of the cremaster, which is organized from the internal oblique and transversus abdominis muscles and their tendon membranes, The inguinal canal is a musculotendinous canal.

BACKGROUND: This study aimed to investigate the safety and feasibility of indocyanine green near-infrared fluorescence (ICG-NIR) fluorescence-guided video-endoscopic inguinal lymphadenectomy (VEIL) for rectal cancer with inguinal lymph node metastasis (ILNM). METHODS: A retrospective analysis was conducted on 11 patients with rectal cancer who underwent ICG-NIR fluorescence-guided VEIL, assessing various parameters such as operation time, intraoperative bleeding, number of harvested lymph nodes, intraoperative and postoperative complications, and follow-up. RESULTS: Regarding surgical procedures for ILNM, unilateral surgery was performed in 7 cases (54.5%) and bilateral surgery in 4 cases (45.5%). Among these 15 ICG-NIR-guided VEIL surgeries in 11 patients, positive fluorescence visualization was achieved in 13 operations (86.7%). The median estimated blood loss was 10 ml, and the median operation time was 90 min. One case (6.7%) required conversion to open surgery. The median duration of the drain tube was 12 days, and the median length of postoperative hospital stay was 20 days. Postoperative complications were observed, including incisional infection in 2 cases (18.2%), lymphatic leakage in 5 cases (45.5%), urinary infection in 1 case (9.1%), and pneumonia in 3 cases (27.3%). Complications such as skin necrosis, lower limb venous thrombosis, lower limb swelling, or impaired movement were observed during the postoperative follow-up period. No cases of primary lesion, groin, or pelvic lymph node recurrence were observed. CONCLUSION: ICG-NIR fluorescence-guided VEIL is a safe and feasible surgical treatment for rectal cancer with ILNM. ICG fluorescence guidance holds promise as a more personalized and precise approach for VEIL in rectal cancer surgery.

The management of lymphatic fistulas following surgical procedures, in particular after inguinal lymphadenectomy, represents a significant clinical challenge. The current case report shows the novel use of the superficial circumflex iliac perforator (SCIP) pedicle vein for lymphovenous anastomosis (LVA) to treat a chronic inguinal lymphatic fistula in a 58-year-old male patient. This patient had developed a persistent lymphorrhea and wound dehiscence after a right inguinal lymph node biopsy performed for oncological reasons 1.5 months before. Pre-operative assessment with indocyanine green (ICG) lymphography confirmed a substantial lymphatic contribution to the wound discharge, thus guiding the surgical strategy. During the procedure, a pedicled tissue segment containing the SCIV was dissected and utilized to fill the wound's dead space and facilitate LVA with the leaking lymphatic vessel. Notably, a coupler device was employed for the anastomosis due to the large caliber of the lymphatic vessel involved, a technique not commonly reported in lymphatic surgeries. The result of the procedure was successful, with intra-operative ICG imaging confirming the patency of the anastomosis. After surgery the wound healed without complications. This case illustrates the potential of SCIV employment in lymphatic fistula repair in the inguinal region. While further research is needed to validate these findings, this report provides an unconventional approach to a relatively common problem in clinical practice.

PURPOSE: Hydrocele is a result of intraperitoneal fluid filling into the scrotum through the patent processus vaginalis (PPV). While the traditional approach of pediatric hydrocele has been open repair (OR) for years, laparoscopic repair (LR) of hydrocele has been accepted worldwide after the proven efficacy of laparoscopy. The purpose is to compare the outcomes of both techniques in a single center. METHODS: We retrospectively analyzed the clinical data of all the patients who underwent hydrocele repair from August 2016 to November 2022. In our center, the standard approach was OR in hydrocele until the November of 2021. Starting from this date, LR has begun to be preferred, as the experience has increased and its success has been observed. In the LR group, single-port percutaneous internal ring suturing technique was performed. RESULTS: The data of 113 patients (OR 58.4% (n = 66), LR 41.6% (n = 47)) were collected. In preoperative examination, 12.4% (n = 14) patients were diagnosed as communicating and 87.6% (n = 99) non-communicating hydrocele. Intraoperatively, 65.5% (n = 74) patients were communicating and 34.5% (n = 39) were non-communicating. Total recurrence rate was 7% (n = 8). The OR group experienced a recurrence rate of 10.6% (n = 7), while the LR group experienced 2.12% (n = 1). CONCLUSION: Laparoscopy may reveal intrabdominal connection of hydrocele better than open approach. It provides a high quality view of both inguinal rings and has the advantages of minimally invasive surgery.

PURPOSE: To present our technical modifications of single incision laparoscopic percutaneous extraperitoneal closure (SILPEC) of the internal inguinal ring (IIR) for pediatric inguinal hernia (PIH). METHODS: The prospectively collected data of all children diagnosed with PIH undergoing SILPEC at our center from 2016 to 2023 were reviewed and divided into two groups for result comparison: Group A: before and Group B: after the implementation of full modifications. Our modifications included using a nonabsorbable monofilament suture, creating a peritoneal thermal injury at the internal inguinal ring (IIR), employing a cannula to ensure the suture at the IIR ligates only the peritoneum, and double ligation of the IIR in selected cases. RESULTS: 1755 patients in group A and in group B (1 month to 14 years old) were enrolled. There were no significant differences regarding baseline patient characteristics between the two groups. At a median follow-up of 40 months, the rate of recurrent CIH and subcutaneous stitch granuloma (SSG) was 2.3% and 1.5% in group A vs. 0% and 0% in group B (p < 0.001). There were no hydroceles, no ascended or atrophic testis. CONCLUSIONS: Our SILPEC technical modifications can achieve zero recurrence and zero SSG for PIH.

PURPOSE: Inguinal lymph node dissection within 3 months of primary tumor resection in penile cancer has been associated with longer recurrence-free and cancer-specific survival. However, the optimal timing and effect of lymphadenectomy performed concurrently at the time of primary lesion management on oncologic outcomes in clinically lymph node positive penile squamous cell carcinoma remains unknown. MATERIALS AND METHODS: An international, multicenter cohort of 966 penile cancer cases was queried for penile squamous cell carcinoma management after the year 2000, clinically lymph node positive status, and performance of penile surgery and inguinal lymph node dissection. Cohorts were stratified as concomitant if inguinal lymph node dissection and penile surgery occurred on the same date or staged when inguinal lymph node dissection was performed after penile resection. Rates and patterns of penile squamous cell carcinoma recurrence were reported. Distant recurrence-free, cancer-specific, and overall survival were estimated using Kaplan-Meier analyses and groups compared with log-rank testing. RESULTS: Of 253 contemporary men with clinically lymph node positive penile squamous cell carcinoma, 96 (38%) underwent concomitant inguinal lymph node dissection and 157 (62%) had inguinal lymph node dissection performed in a staged manner. Penile cancer was most likely to recur distantly (19%) followed by in the groin (14%) or pelvis (5%). There were no differences in distant recurrence-free, cancer-specific, or overall survival between management strategies. Multivariable analysis adjusting for stage, treatment center, and perioperative chemoradiation also demonstrated no recurrence-free, cancer-specific, or overall survival benefit between management strategies. CONCLUSIONS: Inguinal lymph node dissection performed concurrently with excision of the penile tumor for clinically node positive penile squamous cell carcinoma is not associated with differences in recurrence-free, cancer-specific, or overall survival compared to staged lymph node dissection.

PURPOSE: To describe our surgical technique and report the oncological outcomes and complication rates using a fascial-sparing radical inguinal lymphadenectomy (RILND) technique for penile cancer patients with cN+ disease in the inguinal lymph nodes. METHODS: Over a 10-year period, 660 fascial-sparing RILND procedures were performed in 421 patients across two specialist penile cancer centres. The technique used a subinguinal incision with an ellipse of skin excised over any palpable nodes. Identification and preservation of the Scarpa's and Camper's fascia was the first step. All superficial inguinal nodes were removed en bloc under this fascial layer with preservation of the subcutaneous veins and fascia lata. The saphenous vein was spared where possible. Patient characteristics, oncologic outcomes and perioperative morbidity were retrospectively collected and analysed. Kaplan-Meier curves estimated the cancer-specific survival (CSS) functions after the procedure. RESULTS: Median (interquartile range, IQR) follow-up was 28 (14-90) months. A median (IQR) number of 8.0 (6.5-10.5) nodes were removed per groin. A total of 153 postoperative complications (36.1%) occurred, including 50 conservatively managed wound infections (11.9%), 21 cases of deep wound dehiscence (5.0%), 104 cases of lymphoedema (24.7%), 3 cases of deep vein thrombosis (0.7%), 1 case of pulmonary embolism (0.2%), and 1 case of postoperative sepsis (0.2%). The 3-year CSS was 86% (95%Confidence Interval [95% CI] 77-96), 83% (95% CI 72-92), 58% (95% CI 51-66), respectively, for the pN1, pN2 and pN3 patients (p < 0.001), compared to a 3-year CSS of 87% (95% CI 84-95) for the pN0 patients. CONCLUSION: Fascial-sparing RILND offers excellent oncological outcomes whilst decreasing the morbidity rates. Patients with more advanced nodal involvement had poorer survival rates, emphasizing the need for adjuvant chemo-radiotherapy.

PURPOSE: To assess the morbidity of inguinal lymph node dissection (ILND) in penile cancer, then to compare this morbidity with that of ILND performed in the context of skin cancer treatment. METHODS: We retrospectively included all patients having undergone ILND between 1 January 2004 and 31 December 2019 in our centre's urology department in the context of treatment of penile cancer or skin cancer. Postoperative complications were reported in accordance with the Clavien-Dindo classification system. RESULTS: Two hundred forty-two ILNDs were performed in 122 patients with penile cancer and 56 ILNDs were performed in 56 patients with skin cancer. The most common early complication was postoperative fluid collection (lymphocele or haematoma), which complicated 44% of ILNDs overall and 60% of radical lymphadenectomies. The most common late complication was leg lymphoedema, found in up to 36% of radical lymphadenectomies. Major complications (grade ≥ III) were very rare (4% of radical lymphadenectomies). Radical lymphadenectomies resulted in significantly more cases of postoperative fluid collection, skin necrosis and dehiscence, as well as leg lymphoedema, than modified lymphadenectomy techniques. Two factors significantly increasing postoperative morbidity were demonstrated: ASA score = 3 (OR = 3.09) and operating time (OR = 1.01). CONCLUSION: ILNDs are morbid surgical procedures for which the indications must be well defined. However, the complications are almost exclusively minor, for a major oncological benefit.

PURPOSE: In 95% of cases, penile cancer is a squamous cell carcinoma whose specificity is lymphatic spread with the inguinal lymph nodes as the first relay route. Inguinal lymph node dissection is a primordial part of the treatment. The objective was to assess the oncological results of inguinal lymph node dissection in penile cancer at our centre. METHODS: We retrospectively included all patients having undergone inguinal lymph node dissection at our centre between 1 January 2004 and 1 January 2020 for the treatment of penile cancer. Patients for whom lymphadenopathy was palliative were excluded. Depending on indications, the procedures consisted in either dynamic sentinel node biopsy, modified lymphadenectomy or radical lymphadenectomy. All cancers were reclassified using the 2016 TNM classification system. Survival was analysed according to the Kaplan-Meier method. RESULTS: 242 inguinal lymph node dissections were performed in 122 patients. There were 71 pN0 (58%), 9 pN1 (7%), 4 pN2 (3%) and 38 pN3 (31%). Mean follow-up was 51 ± 45 months. The 3-year recurrence-free survival rate was 76% in pN0 patients and 17% in pN3 patients. The 5-year specific and overall survival rates were, respectively, 82% and 73% for pN0 stages, and 14% and 17% for pN3 stages. Extracapsular extension on an inguinal lymphadenopathy appeared as a highly negative prognostic factor. CONCLUSION: Inguinal lymph node dissection is essential in the treatment of penile cancer. Recurrence-free, specific and overall survival are closely linked to the lymph node stage. Extracapsular extension and pelvic lymph node invasion are highly negative prognostic factors.

INTRODUCTION: Chronic pain is a frequent and notable complication after inguinal hernia repair, it has been extensively studied, but its management and diagnosis are still difficult. The cause of chronic pain following inguinal hernia surgery is usually multifactorial. This case series highlights the utility of MRI neurography (MRN) in evaluating the damage to inguinal nerves after a hernia repair, with surgical confirmation of the preoperative imaging findings. MATERIALS AND METHODS: A retrospective review was performed on patients who underwent inguinal mesh removal and triple denervation of the groin. Inclusion criteria included MRI neurography. All patients underwent surgical exploration of the inguinal canal for partial or complete mesh removal and triple denervation of the groin by the same senior surgeon. RESULTS: A total of nine patients who underwent triple denervation were included in this case series. MRN was then performed on 100% of patients. The postoperative mean VAS score adjusted for all patients was 1.6 (SD p), resulting in a 7.5 score difference compared to the preoperative VAS score (p). Since chronic groin pain can be a severely debilitating condition, diagnosis, and treatment become imperative. CONCLUSION: MRN can detect direct and indirect signs of neuropathy even in the absence of a detectable compressive cause aids in management and diagnosis by finding the precise site of injury, and grading nerve injury to aid pre-operative assessment for the nerve surgeon. Thus, it is a valuable diagnostic tool to help with the diagnosis of nerve injuries in the setting of post-inguinal hernia groin pain.

PURPOSE: Inguinal lymph nodes are a rare but recognised site of metastasis in rectal adenocarcinoma. No guideline or consensus exists for the management of such cases. This review aims to provide a contemporary and comprehensive analysis of the published literature to aid clinical decision-making. METHODS: Systematic searches were performed using the PubMed, Embase, MEDLINE and Scopus and Cochrane CENTRAL Library databases from inception till December 2022. All studies reporting on the presentation, prognosis or management of patients with inguinal lymph node metastases (ILNM) were included. Pooled proportion meta-analyses were completed when possible and descriptive synthesis was utilised for the remaining outcomes. The Joanna Briggs Institute tool for case series was used to assess the risk of bias. RESULTS: Nineteen studies were eligible for inclusion, encompassing 18 case series and one population-based study using national registry data. A total of 487 patients were included in the primary studies. The prevalence of ILNM in rectal cancer is 0.36%. ILNM are associated with very low rectal tumours with a mean distance from the anal verge of 1.1 cm (95% CI 0.92-1.27). Invasion of the dentate line was found in 76% of cases (95% CI 59-93). In patients with isolated inguinal lymph node metastases, modern chemoradiotherapy regimens in combination with surgical excision of inguinal nodes are associated with 5-year overall survival rates of 53-78%. CONCLUSION: In specific subsets of patients with ILNM, curative-intent treatment regimens are feasible, with oncological outcomes akin to those demonstrated in locally advanced rectal cancers.

OBJECTIVE: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). MATERIALS AND METHODS: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. RESULTS: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. CONCLUSION: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Adenocarcinoma of the rectum and anal canal with inguinal lymph node metastasis(ILNM)is rare and the prognosis is generally poor. The aim of this study was to clarify the clinical significance of selective inguinal lymph node dissection and total mesorectal excision after preoperative therapy for adenocarcinoma of the rectum and anorectal canal with clinically suspected ILNM. Of the 15 patients, 11 received preoperative chemoradiotherapy, 3 received chemotherapy, and 1 received chemotherapy after chemoradiotherapy. 14 patients received preoperative therapy followed by FDG-PET scans were performed in 14 patients after preoperative treatment. 5 patients had negative FDG accumulation in inguinal lymph nodes on FDG-PET scans, and postoperative pathological diagnosis was also negative for metastasis in the inguinal lymph nodes. Of the 9 patients with positive FDG accumulation, 4 had pathologically positive inguinal lymph nodes, 7 had postoperative inguinal seroma, the 5-year survival rate was 77.5%, and the 5-year recurrence-free survival rate was 64.2%. No patient had a recurrence in the inguinal region. Patients with adenocarcinoma of the rectum and anal canal with clinical ILNM had good long-term survival after radical resection with preoperative therapy.

BACKGROUND: The prevalence and incidence of peripheral arterial disease have been increasing in the general population. Although limited data are available on the epidemiology of chronic limb-threatening ischemia, it likely represents <10% of all patients with peripheral arterial disease. In the general population, its overall prevalence has been 0.74%. This specific subgroup of patients can have severe disease presentations. Their symptoms often correlate with a specific infrainguinal morphologic pattern known as chronic total occlusion (CTO). CTO will often be difficult to cross in a standard endovascular fashion. In previous years, several techniques have been developed to overcome the limitations of standard antegrade endoluminal or subintimal approaches, if these approaches fail. METHODS: We have described the advanced techniques, including subintimal techniques, such as crush balloon, parallel wire, SAFARI (subintimal arterial flossing with antegrade and retrograde intervention), and double-balloon techniques, in detail. Furthermore, we have described a homemade reentry device, which can be used to provide access to the distal true lumen in extreme, uncrossable cases. Retrograde approaches comprise several techniques developed from interventional cardiology techniques. Finally, we have described transcollateral and pedal-plantar loop techniques in detail. RESULTS: These techniques allow endovascular surgeons to successfully encounter even complex anatomies, which will be present in â¼80% of all CTOs. In the present report, we have reviewed all these advanced techniques, correlated the effectiveness of each with the proximal and distal cap morphologic features, and discussed the economic consequences of the endovascular approach considering the costs vs the disease progression and the materials used during the procedures. CONCLUSIONS: Effective use of the advanced techniques we have described is of paramount importance because only 20% of patients will have a CTO that is crossable using standard techniques. Thus, the use of these techniques can help endovascular surgeons increase their success for patients with complex anatomic patterns. Furthermore, the possibility of treating these CTOs using only guidewires and catheters will reduce the costs of the procedures. However, their use in clinical practice still must be standardized.
