RESUMEN
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 article includes a clinical case of a patient with deep infiltrating endometriosis with rectum involving and using intraoperative controlled fluorescence in order to increase the radicality of surgery and improve the prognosis of the disease. Surgical excision of the endometrioitic nodules is the only effective way of treating patients with colorectal endometriosis in terms of relieving pain, improving quality of life and restoring reproductive function. The possible types of surgical interventions can be performed: endometrioid lesion shaving, discoid or circular intestinal resection with anastomosis. The extent of the operation is determined by the following morphological parameters: the number of endometrioid infiltrates of the intestinal wall, the size of each of them, the degree of involvement of the intestine circumference, the depth of the intestinal wall lesion, the distance from the level of anus to the endometriotic nodule and lymphatic dissemination.

BACKGROUND: Cleft lip and palate (CLCP) surgeries necessitate precise airway management, especially in pediatric cases with anatomical variations. The Covid-19 pandemic posed unprecedented challenges to anesthesiology practices that required adaptations to ensure patient safety and minimize viral transmission. Videolaryngoscopy (VL) emerged as a valuable tool in airway management during the pandemic, offering improved intubation success rates and reduced aerosol generation risks. METHODS: This retrospective study compared anesthesiology practices in CLCP surgeries before (2015-2019) and during the Covid-19 (2019-2022) pandemic at a tertiary care center. Patient demographics, anesthesia techniques, intubation difficulty, airway management, and intraoperative and postoperative follow-up were analyzed from anesthesia records. RESULTS: This study included 1282 cases. Demographics were similar between periods. During the pandemic, there was a significant decrease in the number of patients under one year old (p < 0.001) and a higher prevalence of micrognathia and comorbidities (p = 0.001 and p = 0.038, respectively). Difficult intubation and intraoperative complication rates decreased during the pandemic, but they were not statistically significant. VL usage during the pandemic contributed to improved extubating success (p < 0.001). CONCLUSIONS: VL usage and improved patient outcomes were observed during the pandemic, potentially due to proactive measures and infection control protocols. Decision-making processes for extubation and intensive care unit stay became crucial during the pandemic. Understanding the role of VL and its adaptations during the Covid-19 pandemic is vital for optimizing perioperative care in CLCP surgeries and other procedures requiring airway management. The findings highlight the resilience of healthcare systems and the importance of evidence-based practices under challenging circumstances.

PURPOSE: Arthroscopic surgery, with its inherent difficulties on visibility and maneuverability inside the joint, poses significant challenges to surgeons. Video-based surgical navigation (VBSN) has proven to have clinical benefits in arthroscopy but relies on a time-consuming and challenging surface digitization using a touch probe to accomplish registration of intraoperative data with preoperative anatomical models. This paper presents an off-the-shelf laser scanner for noninvasive registration that enables an increased area of reachable region. METHODS: Our solution uses a standard arthroscope and a light projector with visual markers for real-time extrinsic calibration. Nevertheless, the shift from a touch probe to a laser scanner introduces a new challenge-the presence of a significant amount of outliers resulting from the reconstruction of nonrigid structures. To address this issue, we propose to identify the structures of interest prior to reconstruction using a deep learning-based semantic segmentation technique. RESULTS: Experimental validation using knee and hip phantoms, as well as ex-vivo data, assesses the laser scanner's effectiveness. The integration of the segmentation model improves results in ex-vivo experiments by mitigating outliers. Specifically, the laser scanner with the segmentation model achieves registration errors below 2.2 mm, with the intercondylar region exhibiting errors below 1 mm. In experiments with phantoms, the errors are always below 1 mm. CONCLUSION: The results show the viability of integrating the laser scanner with VBSN as a noninvasive and potential alternative to traditional methods by overcoming surface digitization challenges and expanding the reachable region. Future efforts aim to improve hardware to further optimize performance and applicability in complex procedures.

BACKGROUND: Repeated attempts at endotracheal intubation are associated with increased adverse events in neonates. When clinicians view the airway directly with a laryngoscope, fewer than half of first attempts are successful. The use of a video laryngoscope, which has a camera at the tip of the blade that displays a view of the airway on a screen, has been associated with a greater percentage of successful intubations on the first attempt than the use of direct laryngoscopy in adults and children. The effect of video laryngoscopy among neonates is uncertain. METHODS: In this single-center trial, we randomly assigned neonates of any gestational age who were undergoing intubation in the delivery room or neonatal intensive care unit (NICU) to the video-laryngoscopy group or the direct-laryngoscopy group. Randomization was stratified according to gestational age (<32 weeks or ≥32 weeks). The primary outcome was successful intubation on the first attempt, as determined by exhaled carbon dioxide detection. RESULTS: Data were analyzed for 214 of the 226 neonates who were enrolled in the trial, 63 (29%) of whom were intubated in the delivery room and 151 (71%) in the NICU. Successful intubation on the first attempt occurred in 79 of the 107 patients (74%; 95% confidence interval [CI], 66 to 82) in the video-laryngoscopy group and in 48 of the 107 patients (45%; 95% CI, 35 to 54) in the direct-laryngoscopy group (P<0.001). The median number of attempts to achieve successful intubation was 1 (95% CI, 1 to 1) in the video-laryngoscopy group and 2 (95% CI, 1 to 2) in the direct-laryngoscopy group. The median lowest oxygen saturation during intubation was 74% (95% CI, 65 to 78) in the video-laryngoscopy group and 68% (95% CI, 62 to 74) in the direct-laryngoscopy group; the lowest heart rate was 153 beats per minute (95% CI, 148 to 158) and 148 (95% CI, 140 to 156), respectively. CONCLUSIONS: Among neonates undergoing urgent endotracheal intubation, video laryngoscopy resulted in a greater number of successful intubations on the first attempt than direct laryngoscopy.

Objective: To report outcomes of multicenter series of penile cancer patients undergoing robot-assisted video endoscopic inguinal lymph node dissection (RA-VEIL). Materials and Methods: In this retrospective analysis from 3 tertiary care centers in India, consecutive intermediate-/high-risk carcinoma penis (CaP) patients with nonpalpable inguinal lymphadenopathy and/or nonbulky (<3 cm) mobile inguinal lymphadenopathy undergoing RA-VEIL were included. Patients with matted/bulky (>3 cm) and fixed lymphadenopathy were excluded. Demographic, clinical, and intraoperative data were recorded. Perioperative complications were graded by the Clavien-Dindo classification (CDC). The International Society of Lymphology (ISL) {0-III} grading was used for the assessment of lymphedema. Incidence and pattern of recurrences were assessed on follow-up. Results: From January 1, 2011, to September 30, 2023, 115 patients (230 groins) underwent bilateral RA-VEIL for CaP. The median age of the cohort was 60 (50-69) years. Clinically palpable (either unilateral or bilateral) inguinal lymphadenopathy was seen in 54 patients (47%). The "per groin" median operative time was 120 (100-140) minutes with median lymph node yield of 12 (9-16). No complications were recorded in 87.8% groins operated, with major complications (CDC 3) seen in 2.6% groins. At a median follow-up of 13.5 months, 13 patients had documented recurrences and there were 10 cancer-related deaths. No port-site recurrences were observed. No/minimal lymphedema (ISL 0/I) was seen in 94% legs. Conclusion: RA-VEIL demonstrates safety and oncologic efficacy in penile cancer patients presenting with clinically nonpalpable and/or nonbulky inguinal lymphadenopathy, with favorable functional outcomes.

BACKGROUND: Anal fistula and perianal abscess are commonly acquired anorectal pathologies in children. Surgical treatment options commonly adopted are fistulotomy, fistulectomy, cutting seton placement, and more recently video-assisted anal fistula treatment (VAAFT). Optimal postoperative wound dressing remains debated. This study aimed to report our series of pediatric patients, who received VAAFT and postoperative wound dressing using ozonide oil. METHODS: All patients who underwent VAAFT between August 2018 and May 2023 were included in the study. Demographics, clinical features, pre-operative imaging, surgical details, outcome, and mid-term outcome data were retrospectively reviewed for each patient. All VAAFT procedures were performed under general anesthesia and using a 10-Ch fistuloscope. RESULTS: Thirty-three VAAFT procedures were performed in 30 patients over the study period. The median patient age was 5.7 years (range 1.75-14). Anal fistula was idiopathic in 26/30 (86.6%), iatrogenic in 2/30 (6.7%), and secondary to Crohn's disease in 2/30 (6.7%). The median duration of surgery was 23 min (range 18-40). All patients received ozonide oil dressing twice a day for 5 weeks postoperatively. The median hospital stay was 24 h (range 9-36). The median healing time was 28 days (range 17-39). With a median follow-up of 2 years (range 0.5-5), disease recurrence occurred in 3/30 (10%) patients with idiopathic fistula, who were re-operated using the same technique, with no further recurrence. No fecal incontinence or soiling was observed. CONCLUSION: Our series confirmed that VAAFT is a safe and effective technique to treat children with perianal fistula. The technique is versatile, allowing to treat fistulae of different etiologies. Postoperative course was painless and fast. Future comparative prospective studies are needed to better establish these conclusions.

INTRODUCTION: Video-assisted telescope operating monitor (VITOM®) with 3D Visualization technology was developed and has been used with favorable results by several surgical specialties. Our study aims to be a preliminary report for initial experience using the VITOM® 3D system for microsurgical varicocelectomy on varicocele patients. METHODS: We performed 35 microsurgical varicocelectomy procedures using the VITOM® 3D system on varying types and grades of varicoceles. The surgeon had the option of using either a 2.5 or 3.5 magnifying loupe in addition to the exoscope for each operation evaluated. The exoscope is a standalone camera head with an integrated 3D telescope and remote control with zoom and focus functions. It is connected to the 3D monitor via a mechanical holding arm. During the procedure, surgeons, assistants, and observers were able to view the 3D high-definition stream displayed on a 26-inch 3D monitor at a convenient viewing angle and distance. The varicocele ligation was performed using a Carl Zeiss Meditec AG microscope. RESULTS: There were 35 patients with varicocele aged 31.51 years old on average, which were included in this report. Most patients had grade 3 bilateral varicocele (n = 13, 37.1%). All procedures were performed without any intraoperative complications. After the procedures, only a few patients suffered from postoperative complications. Three patients suffered scrotal edema (8.6%), while another had hydrocele (2.9%). The postoperative pain results were also very minimal from .89 1 day after the operation to .26 3 days after the operation. CONCLUSION: The VITOM® 3D system showed promise in microsurgical varicocelectomy.

BACKGROUND: Transoral videolaryngoscopic surgery (TOVS) is widely used in Japan, and conventional two-dimensional (2D) endoscopic methods have been established. Three-dimensional (3D) endoscopic surgery offers superior distance perception because it provides stereoscopic views. Recently, we have developed 3D endoscopy for TOVS (3D TOVS). METHODS: This study included 46 patients with pharyngeal cancer who underwent 3D TOVS. The perioperative complications and survival curves were retrospectively analyzed. RESULTS: One patient with oropharyngeal cancer who underwent neck dissection and transoral resection simultaneously experienced postoperative hemorrhage of the neck. Another patient with oropharyngeal cancer underwent hemostasis for postoperative pharyngeal hemorrhage. There was one case of aspiration pneumonia. One patient developed cervical lymph node recurrence; however, there was no local recurrence or primary mortality. The 2-year overall survival, disease-specific survival, local control rates, locoregional control rate, and invasive disease-free survival were 90.9%, 100%, 100%, 97.4%, and 79.9%, respectively. CONCLUSIONS: Three-dimensional endoscopy can be safely applied to TOVS.

PURPOSE: The objective of this study was to demonstrate, based on objective clinical indicators, the advantages of depth of field provided by the 3D surgical video system compared with the traditional microscope during vitrectomy for treating epiretinal membranes or macular holes. METHODS: A total of 38 patients were included in this study and randomly assigned to either the 3D surgical video group or the conventional microscope group. Surgical parameters, such as the focal plane adjustment frequency, membrane peeling time, and number of attempts to peel the membrane, were recorded for each patient. In addition, patients were followed up for 3 months postoperatively. RESULTS: No significant differences were observed in age, sex, operated eyes, or follow-up rates between the groups. The 3D group had significantly lower focal plane adjustment frequency in macular hole surgery and epiretinal membrane surgery. No significant differences were observed in peeling maneuvers, time, or total surgical time. Postoperative follow-up data showed no significant differences. CONCLUSION: In conclusion, the 3D surgical video system exhibits potential advantages in depth of field. The 3D surgical video system is a safe and effective technology in vitrectomy for macular diseases.

Introduction: Innovation is not a straightforward path. While surgeons are intimately familiar with clinical problems and often devise clever solutions to address them, the journey from idea to a marketable product is opaque. We describe our experience developing a novel video navigation system to help streamline collaboration and enhance surgeon control of their video image in minimally invasive surgery. Materials and Methods: Our idea began with recognizing the primary clinical challenge: "one bad image for all" in laparoscopic surgery, when the least experienced member of the surgical team is often expected to hold the camera. Results: Through multiple iterations and pivots, including hardware-based solutions like head-mounted displays and individualized monitors, we arrived at a hardware-agnostic software algorithm to process laparoscopic video for real-time image navigation. As we explain why, how, and when to pivot, we provide brief overviews of protecting intellectual property and financing innovation. Finally, collaboration with professional societies, such as the International Pediatric Endosurgery Group, provides fertile testing grounds for new ideas. Conclusion: Our experience may help future surgeon-innovators go from their ideas to industry-ready.

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.

AIM: Complex anal fistula represents a burden for patients, and its management is a challenge for surgeons. Video-assisted anal fistula treatment (VAAFT) is one sphincter-sparing technique. However, data on its long-term effectiveness are scant. We aimed to explore the outcomes of VAAFT in a retrospective cohort of patients referred to a tertiary centre. METHOD: Consecutive adult patients with a minimum of 2 years' follow-up after VAAFT were reviewed. Patients were followed up to 5 years postoperatively. Failure was defined as incomplete healing of the external orifice(s) during the first 6 months. Recurrence was defined as new radiologically and/or clinically confirmed onset of the fistula after primary healing. A generalized linear model was fitted to evaluate the association between failure and sociodemographic characteristics. Predictors of recurrence were determined in a subgroup analysis of patients found to be free from disease at 6 months postoperatively. RESULTS: Overall, 106 patients (70% male; mean age 41 years) were reviewed. Of these 86% had a previous seton placement. Fistulas were either high trans-sphincteric (74%), suprasphincteric (12%) or extrasphincteric (13%). Eight (7%) patients experienced postoperative complications, none of which required reintervention. Mean follow-up was 53 ± 13.2 months. VAAFT failed in 14 (13%) patients. The overall recurrence rate ranged from 29% at 1 year to 63% at 5 years. Multiple external orifices, suprasphincteric fistula, younger age, previous surgery and higher complexity of the fistulous tract were independent risk factors for recurrence. CONCLUSION: VAAFT is a safe sphincter-sparing technique. The initially high success rate decreases over time and relates to a higher degree of complexity.

Complex anal fistulas (CAF) present a challenge in achieving healing while preserving anal sphincter function. This study aims to introduce a novel staged approach for CAF treatment, combining video-assisted anal fistula treatment (VAAFT), seton placement, and other staged approaches. Consecutive patients with CAF underwent the staged approach involving VAAFT and seton placement. Data on patient demographics, fistula characteristics, and operative findings were collected. Pre-operative work-up included clinical evaluation, endoanal ultrasonography (EAUS), and magnetic resonance imaging (MRI). Surgical techniques and outcomes were evaluated. Eighteen patients (median age 38 years) were included. Misplacement of a previously placed seton was observed in 64% of cases. VAAFT combined with seton placement achieved simplification and healing of secondary tracts in 66% of cases. Operative times significantly decreased across interventions. At a median follow-up of 14 months, complete healing was achieved in 2 patients, with 1 patient demonstrating persistence of the fistula. Post-operative complications were observed in 11% of patients, with no deterioration in continence. The staged approach combining VAAFT, seton placement, and staged procedures offers a potential solution for treating CAF. VAAFT provides diagnostic and therapeutic benefits, simplifying the fistula anatomy and optimizing seton placement. The approach allows subsequent procedures based on individual fistula characteristics.

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.

BACKGROUND: Videolaryngoscopes may not be as effective in small children as they are in older children and in adults. The size 1 blade is commercially available for the McGRATH®MAC videolaryngoscope (Covidien, Medtronic, Tokyo, Japan), but its efficacy in comparison with a Macintosh laryngoscope blade 1 is not known. AIM: The main aim of this study was to assess the efficacy of McGrath®MAC blade 1 in comparison with a conventional Macintosh laryngoscope blade 1, in children aged less than 24 months. METHODS: Thirty-eight children aged less than 24 months were randomly allocated to one of two groups, and tracheal intubation was attempted using either a direct laryngoscope with a Macintosh blade 1 or a videolaryngoscope with a McGRATH®MAC blade 1. In another 12 children aged 2-4 years, the same comparisons were made with blade 2. The primary outcome measure was time to tracheal intubation using a size 1 blade. RESULTS: Tracheal intubation took significantly longer with a McGRATH®MAC blade 1 (median (interquartile range): 38.0 (31.8-43.5) s) than with the Macintosh blade 1(27.4 (25.9-29.2) s) (p < 0.0001; median difference (95% CI for the median difference): 10.6 (6.4-14.0) s), mainly due to difficulty in advancing a tube into the trachea. No significant difference was observed for the size 2. CONCLUSIONS: In small children without predicted difficult airways, time to intubate the trachea was significantly longer for a McGRATH®MAC blade 1 than a Macintosh blade 1. CLINICAL TRIAL REGISTRATION: jRCT1032220366.

BACKGROUND: Inguinal lymph node dissection (ILND) is an essential step in both treatment and staging of several malignancies including penile and vulvar cancers. Various open, video endoscopic, and robotic-assisted techniques have been utilized so far. In this review, we aim to describe available minimally invasive surgical approaches for ILND, and review their outcomes and complications. METHODS: The PubMed, Wiley Online Library, and Science Direct databases were reviewed in February 2020 to find relevant studies published in English within 2000-2020. FINDINGS: There are different minimally invasive platforms available to accomplish dissection of inguinal nodes without jeopardizing oncological results while minimizing postoperative complications. Video Endoscopic Inguinal Lymphadenectomy and Robotic Video Endoscopic Inguinal Lymphadenectomy are safe and achieve the same nodal yield, a surrogate metric for oncological adequacy. When compared to open technique, Video Endoscopic Inguinal Lymphadenectomy and Robotic Video Endoscopic Inguinal Lymphadenectomy may offer faster postoperative recovery and fewer postoperative complications including wound dehiscence, necrosis, and infection. The relatively high rate and severity of postoperative complications hinders utilization of recommended ILND for oncologic indications. Minimally invasive approaches, using laparoscopic or robotic-assisted platforms, show some promise in reducing the morbidity of this procedure while achieving adequate short and intermediate term oncological outcomes.

AIM: Pilonidal sinus or Pilonidal Disease (PD) is a relatively common, benign but challenging condition. Although commonly encountered in practice, its ideal treatment is controversial. One of the most validated treatments is video-assisted surgery. In this context, very similar endoscopic techniques have been published under different names. The aim of this systematic review is to assess the differences among these proposed techniques and their outcomes. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed during all stages of this systematic review. A systematic search of the English literature was performed on multiple databases from 1 January 2014 to 3 April 2022. The primary outcome measure was the IDEAL framework stage of innovation. The key secondary outcome measures were the adherence to the IDEAL reporting guidelines, the Blencowe framework and the core outcome set (COS) for studies evaluating the introduction and evaluation of novel surgical techniques, the qualitative assessment using appropriate tools, the procedural variations and outcomes of each technique. RESULTS: A total of 38 articles were included reporting a very similar technique under eight different acronyms. The number of patients varied from 9 to 250. Mean follow-up ranged from 1 to 60 months. There was only one published study of IDEAL 3. The majority (58%) were IDEAL 2a studies. Reporting of domains in the IDEAL reporting guidelines and Blencowe framework was poor, with most studies not reporting the component steps of procedures or efforts to standardize them. Half of COS domains were markedly underreported. The quality of the evidence was categorized as having a risk of bias from moderate to critical level in all nine comparative non-randomized series. Postoperative complications occurred in 0%-6% of cases, including surgical site infection, poor or failed wound healing bleeding, granuloma, haematoma, and pain requiring intervention. The recurrence rate varied from 0% to 22%. CONCLUSION: The study demonstrates that reporting on technical aspects of interventions for PD is poor, thus warranting a better-quality control of surgical techniques. It is advisable to group all endoscopic procedures under the umbrella term of 'endoscopic sinusectomy', thus embracing the two main principles of this technique, that is, video assistance and PD ablation.

Inguinal lymph node status is the single most important prognostic factor for survival in patients with carcinoma penis. Various modifications and alternatives to open inguinal lymph node dissection have been developed as the same is associated with high postoperative morbidity such as wound infection, skin flap necrosis, lymphorrhea, and lymphedema. Robot-assisted video endoscopic inguinal lymph node dissection (RA-VEIL) has the potential to accomplish thorough inguinal lymph node dissection with definitively reduced postoperative morbidity. In this video, we demonstrate our technique of RA-VEIL: The fascia lata first approach and highlight our technical modifications of the conventionally described procedure.

To compare minimally invasive video-assisted parathyroidectomy (MIVAP) versus conventional surgery for renal hyperparathyroidism (rHPT). Between 2006 and 2020, 53 patients underwent MIVAP and 182 underwent conventional parathyroidectomy for rHPT at the Kliniken Essen-Mitte and Knappschaftskrankenhaus Bochum, respectively. Two propensity score-matched groups were retrospectively analyzed: the MIVAP group (VG; n = 53) and the conventional group (CG; n = 53). To assess long-term results, the patients were questioned prospectively (VG; n = 17, and CG; n = 26). The VG had a smaller incision (2.8 vs. 4.8 cm), shorter operation duration (81.0 vs. 13.9 min), and shorter duration of stay (2.4 vs. 5.7 days) (p < 0.0001) but a smaller drop in parathyroid hormone (PTH) postoperatively (81.3 vs. 85.5%. p = 0.022) than the CG. The conversion rate was 9.4% (n = 5). The VG had better Patient Scar Assessment Scale (PSAS) scores (10.8 vs. 11.7 p = 0.001) but worse SF-12 health survey scores (38.7 vs. 45.8 for physical health and 46.7 vs. 53.4 for mental health) (p < 0.0001). The PTH level at follow-up was higher in the VG (162.7 vs. 59.1 ng/l, p < 0.0001). There were no differences in morbidity, number of removed parathyroid glands, disease persistence, late rHPT relapse and need for repeat surgery between groups. MIVAP was superior to conventional parathyroidectomy regarding aesthetic outcomes and cost effectiveness. Conventional surgery showed better control of PTH levels and health scores on follow-up than MIVAP, without any impact on rHPT relapse and need for repeat surgery.Trail registration number and date of registration: DRKS00022545 on 14.12.2020.
