BACKGROUND
Ilio-inguinal lymphadenectomy for stage III melanoma and skin cancers still represents the best therapeutic option for a subset of patients, although the incidence of post-operative complications is dramatically high. Only a paucity of papers on robotic approach have been published, reporting experiences on isolated pelvic or inguinal lymphadenectomy, and no series on combined dissections have been described yet. We present the preliminary results achieved with combined robotic approach, with special emphasis on lymph nodal mapping, dissection technique and postoperative complications linked with the lymphatic system.
METHODS
Between September 2019 and September 2021, 10 patients were submitted to robotic inguinal and iliac-obturator lymphadenectomy.
RESULTS
Post-operative course was characterised by early mobilisation and minimal post-operative pain. Only one lymphoedema occurred and lymph nodal harvesting was more than satisfactory.
CONCLUSIONS
Robotic surgery provides meticulous lymph nodal dissections, with promising functional and oncologic outcomes. Further series are advocated to confirm these preliminary results.

INTRODUCTION AND OBJECTIVE
Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for muscle invasive bladder cancer and the oncologic outcomes following it are directly related to disease pathology and surgical technique. Therefore, we sought to analyze these features in a cohort from a Brazilian tertiary oncologic center and try to identify those who could negatively impact on the disease control.
PATIENTS AND METHODS
We identified 128 patients submitted to radical cystectomy, for bladder cancer treatment, from January 2009 to July 2012 in one oncology tertiary referral public center (Mario Penna Institute, Belo Horizonte, Brazil). We retrospectively analyzed the findings obtained from their pathologic report and assessed the complications within 30 days of surgery.
RESULTS
We showed similar pathologic and surgical findings compared to other large series from the literature, however our patients presented with a slightly higher rate of pT4 disease. Positive surgical margins were found in 2/128 patients (1.5%). The médium number of lymph nodes dissected were 15. Major complications (Clavien 3 to 5) within 30 days of cystectomy occurred in 33/128 (25.7%) patients.
CONCLUSIONS
In the management of invasive bladder cancer, efforts should focus on proper disease diagnosis and staging, and, thereafter, correct treatment based on pathologic findings. Furthermore, extended LND should be performed in all patients with RC indication. A critical analysis of our complications in a future study will help us to identify and modify some of the factors associated with surgical morbidity.

With the increasing incidence of gynecologic malignancy, radical hysterectomy represents an important part of the adequate treatment of these patients. The pelvic lymphocele is a known side effect of pelvic and para-aortic lymphadenectomy. The aim of our study was to assess the role of the lymphocele in the development of early postoperative complications.A single-center, retrospective analysis between January 2000 and May 2017 revealed 1867 patients with cervical and endometrial cancer, treated through radical or modified radical hysterectomy and pelvic lymphadenectomy. Postoperative complications and the occurrence of pelvic lymphocele were evaluated.Approximately 47.6% of patients were diagnosed with pelvic lymphocele, with only 5.2% being symptomatic. Early postoperative complications rate recorded an incidence of 8.1%, occurring more frequent if lymphocele were present (P < .001). The pelvic lymphocele represented, in univariate analysis, a risk factor for the development of pelvic abscesses, but not for deep vein thrombosis, lymphedema, or bowel obstruction. Hydronephrosis was found to be significantly correlated with the pelvic lymphocele, but we believe this urological complication to have a different underlining mechanism. Neoadjuvant radiotherapy represented in both uni- and multivariate analysis a risk factor for the occurrence of postoperative complications.In the postoperative context of oncogynecological surgery, pelvic lymphocele occur at high rates, representing a statistical risk factor for hydronephrosis and pelvic abscesses, with neoadjuvant radiotherapy being an independent risk factor for early postoperative complications.

Review
The sentinel node evaluation has revolutionized the modern surgical management of cutaneous melanoma and breast cancer. In gynecologic oncology, sentinel node mapping has been mainly studied in vulvar and cervical cancer. In vulvar cancer, data from 12 studies including 353 cases indicate that the sentinel node detection rate is 92% and the negative-predictive value is 99%. Three groin recurrences have been documented so far (< 1%). The technique has more recently been studied in cervical cancer. Data from 12 studies including 323 cases indicate a lower sentinel node detection rate of 80% to 86% and a negative-predictive value of 99%. Three false-negative cases have been reported so far (< 1%). Review of the literature suggests that the combined approach with blue dye and lymphoscintigraphy is superior to the blue dye alone for sentinel node detection. It also suggests that the sentinel node mapping technique is feasible in vulvar and cervical cancer and that it may become a valuable alternative to the traditional groin and pelvic lymphadenectomy. However, results have not been duplicated in large multi-institutional trials, and the technique should still be performed in the context of clinical trials. Complications of the sentinel node mapping technique are rare and usually benign but physicians should be aware of the serious risk of anaphylactic reaction to the blue dye (1% to 2%). Before this technique becomes a standard approach in the management of gynecologic malignancies, more data will be needed to clarify some of the related controversies.

Review
In the era of neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision, overall oncological outcomes after curative resection of rectal cancer are excellent, with local recurrence rates as low as 5-10%. However, lateral nodal disease is a major cause of local recurrence after neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision. Patients with lateral nodal disease have a local recurrence rate of up to 30%. The oncological benefits of lateral pelvic lymph node dissection (LPLND) in reducing local recurrence, particularly in the lateral compartment, have been demonstrated. Although LPLND is not standard in Western countries, technical improvements in minimally invasive surgery have resulted in rapid technical standardization of this complicated procedure. The feasibility and short- and long-term outcomes of laparoscopic and robotic LPLND have been reported widely. A minimally invasive approach has the advantages of less bleeding and providing a better surgical view of the deep pelvic anatomy than an open approach. With precise autonomic nerve preservation, postoperative genitourinary dysfunction has been reported to be minimal. We review recent evidence on the management of lateral nodal disease in rectal cancer and technical improvements of LPLND, focusing on laparoscopic and robotic LPLND.

Since sentinel lymph node mapping in endometrial cancer is becoming more widely used, the need of standardizing surgical technique is growing [1, 2]. The objective of this surgical video is to describe the procedure of two-step pelvic and para-aortic sentinel lymph node mapping using indocyanine green and fluorescent camera in endometrial cancer, in three versions of surgical modality of laparoscopic, robotic, and open laparotomy. The patients in the surgical video are diagnosed with biopsy-proven endometrial cancer in its early stage determined by the preoperative imaging study. After collecting washing cytology, bilateral salpinges were clamped with Endo Clip™ to minimize tumor spillage. Gauze packing in posterior cul-de-sac was done to minimize the spillage of indocyanine green dye during paraaortic sentinel lymph node mapping. Indocyanine green dye was injected in bilateral uterine fundus, to detect isolated paraaortic sentinel lymph node pathway. After bilateral paraaortic sentinel lymph node was sampled, cervical injection of Indocyanine green dye was done in 3 o'clock and 9 o'clock directions, both superficially and deeply, 2 mL in each side. After dissecting off the obliterated umbilical ligament, para-vesical and para-rectal spaces were developed. The ureter, uterine artery, and internal and external iliac vessels were identified before bilateral pelvic sentinel lymph nodes were sampled. Asan Medical Center's Institutional Review Board exempted this project. Sentinel paraaortic and pelvic lymph nodes were successfully harvested by two-step method of sentinel lymph node mapping through laparoscopic, robotic, and open laparotomy methods. This surgical video provides specific steps of pelvic and para-aortic sentinel lymph node mapping.

Review
Jejunal obstruction due to rare internal hernia between skeletonized external iliac artery and vein as late complication of laparoscopic hysterectomy with pelvic lymphadenectomy-case report and review of literature.
BACKGROUND
Internal herniation of small intestine in the lesser pelvis alongside iliac vasculature is a rare occurrence. Skeletonization of iliac vessels during pelvic lymph node dissection (LND), as part of surgical staging or treatment of patients with uterine, ovarian or urogenital cancer, is a strict prerequisite for orifice formation.
CASE PRESENTATION
A 68-year-old woman presented at the emergency department with complaints of constipation for the last 3 days and acute-onset abdominal pain, nausea and vomiting since few hours. She had a history of laparoscopic hysterectomy, bilateral salpingo-oophorectomy and para-aortic and pelvic LND 7 years ago. A distended abdomen with diffuse tenderness on palpation was noted. A CT scan demonstrated bowel obstruction secondary to an incarcerated hernia underneath an elongated right external iliac artery. During an emergency exploratory laparotomy, the incarcerated bowel was reduced and the hernial orifice closed with a running suture. The patient had an uneventful postoperative period and was discharged on the fifth postoperative day.
DISCUSSION
This rare internal hernia can manifest with non-specific symptoms of small bowel obstruction at any given point after index surgery, sometimes even after several years free of complaints. Contrast-enhanced computed tomography is the method of choice for fast and reliable diagnosis and helps in planning the necessary emergency laparotomy.
CONCLUSION
This life-threatening complication adds to the current controversy of pelvic and para-aortic lymphadenectomy in patients with endometrial cancer. Primary closure of peritoneal defects should be considered to potentially prevent internal hernias, especially when elongated iliac vessels are present.

BACKGROUND
Inguinal lymph node dissection (ILND) is used for diagnosis and treatment in penile cancer (PC), vulvar cancer (VC), and melanomas draining to the inguinal lymph nodes. However, ILND is often characterized by its morbidity and high wound complication rate. Consequently, we aimed to characterize wound complication rates after ILND.
STUDY DESIGN
The NSQIP database was queried for ILND performed from 2005 to 2018 for melanoma, PC, or VC. Thirty-day wound complications included wound disruption and superficial, deep, and organ-space surgical site infection. Multivariable logistic regression was performed with covariates, including cancer type, age, American Society of Anesthesiologists score ≥3, BMI ≥30, smoking history, diabetes, operative time, and concomitant pelvic lymph node dissection.
RESULTS
A total of 1,099 patients had an ILND with 92, 115, and 892 ILNDs performed for PC, VC, and melanoma, respectively. Wound complications occurred in 161 (14.6%) patients, including 12 (13.0%), 17(14.8%), and 132 (14.8%) patients with PC, VC, and melanoma, respectively. Median length of stay was 1 day (interquartile range 0 to 3 days), and median operative time was 152 minutes (interquartile 83 to 192 minutes). Readmission rate was 12.7%. Wound complications were associated with longer operative time per 10 minutes (odds ratio 1.038, 95% CI 1.019 to 1.056, p < 0.001), BMI ≥30 (odds ratio 1.976, 95% CI 1.386 to 2.818, p < 0.001), and concomitant pelvic lymph node dissection (odds ratio 1.561, 95% CI 1.056 to 2.306, p = 0.025).
CONCLUSIONS
Predictors of wound complications after ILND include BMI ≥30, longer operative time, and concomitant pelvic lymph node dissection. There have been efforts to decrease ILND complication rates, including minimally invasive techniques and modified templates, which are not captured by NSQIP, and such approaches may be considered especially for those with increased complication risks.

OBJECTIVE
Detection of lymph node involvement in women with IB2-IIB cervical cancer could have a positive effect on survival. We set out to evaluate the incidence of pelvic and/or para-aortic lymph node involvement using the sentinel node (SN) biopsy and its impact on survival.
METHODS
From 2002 to 2010, 66 women with IB2-IIB cervical cancer underwent a pelvic and paraaortic lymphadenectomy with SN biopsy. Survival between groups according to lymph node status was evaluated.
RESULTS
Mean tumour size was 43.5 mm. At least one SN was detected in 69% of the 45 SN procedures performed. Sixteen of these patients had metastatic SN and the false negative rate was 20%. Metastatic pelvic SNs or non-SNs were detected in 33 patients (50%), including pelvic-positive nodes in 26 (40%), pelvic- and paraaortic-positive lymph nodes in seven (11%), and paraaortic skip metastases in two (6%). Positive paraaortic node was the sole determinant for disease-free survival (DFS) and overall survival (OS; P<0.001). Differences in DFS and OS between groups according to the nodal status were observed (P<0.001).
CONCLUSION
SN procedure gave a higher rate of metastasis detection. Further studies are required to evaluate whether pre-therapeutic node staging, including paraaortic and pelvic lymphanedectomy, should be performed.
