Video versus Direct Laryngoscopy for Urgent Intubation of Newborn Infants.

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.

Video-assisted anal fistula treatment (VAAFT) combined with ozonide oil dressing: standardization of technique in pediatric patients.

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.

OBJECTIVE QUANTIFICATION OF DEPTH-OF-FIELD ADVANTAGE IN 3D SURGICAL VIDEO SYSTEM FOR VITREORETINAL SURGERY: Safety and Efficacy in Macular Diseases.

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.

Indocyanine green near-infrared fluorescence-assisted video endoscopic inguinal lymph node dissection for rectal cancer: a single-center experience.

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.

Video-Assisted Telescope Operating Monitor 3D System in Microsurgical Varicocelectomy: A Preliminary Report.

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.

[Implementation of fluorescent imaging technology in endovideosurgical treatment of colorectal endometriosis]. / Vnedrenie tekhnologii fluorestsentnoi vizualizatsii v endovideokhirurgicheskoe lechenie kolorektal'nogo endometrioza.

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.

The impact of videolaparoscopic surgery in the treatment of endometriosis on depression levels.

OBJECTIVE: The aim of the study was to evaluate the impact of laparoscopic surgical treatment of endometriosis on the levels of health-related depression in patients using a validated questionnaire. METHODS: A prospective study was carried out between September 2020 and May 2022 in a private hospital (São Luís, Maranhão, Brazil), which analysed depression using the Beck Depression Inventory-II, on 103 patients undergoing surgical treatment for endometriosis, evaluated preoperatively and 3 and 6 months after the procedure. Patients with unsuccessful clinical treatment for endometriosis and pain level ≥7 on Visual Analog Scale and who agreed to participate in the study were included. Demographic data were acquired by consulting medical records. RESULTS: The average age of the participants was 36±6.3 years; the majority of patients were brown (68.6%), married (66.6%), overweight (55.8%), had had hormonal treatments with progestogens (50.9%), low fertility (50.9%), severe endometriosis (39.3%), endometriosis surgery+myomectomy (29.4%) and one (1%) patient withdrew from the study. There was a statistically significant reduction in mean Beck Depression Inventory between the preoperative period and 6 months after surgery (p<0.0001). CONCLUSION: Surgical treatment of endometriosis appears to have a positive impact on the symptoms of depression in the patients evaluated.

Robot-Assisted Video Endoscopic Inguinal Lymph Node Dissection for Penile Cancer: An Indian Multicenter Experience.

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.

Safety and outcome of three-dimensional transoral videolaryngoscopic surgery.

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.

Structured light for touchless 3D registration in video-based surgical navigation.

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.

The role of videolaryngoscopy in cleft surgery: A single center comparative study before and during the COVID-19 pandemic.

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.

Resolución por videolaparoscopia del síndrome de ligamento arcuato en pediatría / Videolaparoscopic management of arcuate ligament syndrome in pediatric patients

El síndrome de ligamento arcuato medio caracterizado por dolor posprandial se debe a la compresión del tronco celíaco por dicho ligamento. En pediatría su presentación es infrecuente. Niña de 14 años con dolor abdominal recurrente. Se diagnosticó por ecografía un aumento de la velocidad del flujo del tronco celíaco con inversión de flujo. La angiotomografía evidenció la compresión. Su resolución fue quirúrgica mediante la sección del ligamento arcuato por videolaparoscopia. Los síntomas desaparecieron inmediatamente luego de la cirugía y no recurrieron en 24 meses de seguimiento. El ligamento arcuato es una banda fibrosa en la crura diafragmática. El nacimiento del tronco celíaco en la aorta supradiafragmática conlleva que este ligamento comprima durante la espiración con isquemia distal transitoria. El diagnóstico se realiza con ecografía Doppler del tronco celíaco o angiotomografía, entre otros. La resolución quirúrgica consiste en la sección del ligamento arcuato. Este síndrome debe tenerse en cuenta ante un caso de dolor abdominal recurrente. La vía laparoscópica es sugerida para el tratamiento

Median arcuate ligament syndrome, which is characterized by post-prandial pain, occurs as a result of the compression of the celiac trunk by the ligament. It is a rare pathology in pediatric patients. We present the case of a 14-year-old girl with recurrent abdominal pain. Ultrasound examination showed an increase in celiac trunk flow rate with flow reversal, while CT angiography demonstrated compression. It was surgically managed by dividing the arcuate ligament through videolaparoscopy. Symptoms disappeared right after surgery and did not reappear in the 24-month follow-up. The arcuate ligament is a fibrous band located at the level of the diaphragmatic crus. The fact that the celiac trunk originates at the supradiaphragmatic aorta makes the ligament exert compression during expiration, with transitory distal ischemia. Diagnosis is achieved through Doppler ultrasonography of the celiac trunk or CT angiography, among others. Surgical management involves dividing the arcuate ligament. This syndrome should be considered in the presence of recurrent abdominal pain. The laparoscopic route is the treatment approach suggested

Histerectomía videolaparoscópica / Videolaparoscopic Hysterectomy

Comparison between curettage adenoidectomy and endoscopic-assisted microdebrider adenoidectomy in terms of Eustachian tube dysfunction / Comparação entre adenoidectomia por curetagem e adenoidectomia por microdebridador assistida por endoscopia, em relação à disfunção tubária

Abstract Introduction Adenoidectomy can be performed with many ways, including curettage and microdebrider endoscopic-assisted adenoidectomy. Those two techniques have advantages and disadvantages. Objective The objective of this study is to research the effects of curettage adenoidectomy and endoscopic-assisted microdebrider adenoidectomy on the tympanum pressures in pediatric patients with adenoid hypertrophy without otitis media with effusion. Methods This prospective descriptive study was performed with 65 patients who had a normal tympanic membrane and normal tympanogram and then underwent adenoidectomy or adenotonsillectomy for adenoid and tonsil hypertrophy. The subjects were randomly divided into two groups: curettage adenoidectomy group and endoscopic microdebrider-assisted adenoidectomy group. They underwent tympanometry, and the preoperative as well as 1st and 7th day postoperative values of the tympanum pressures were compared within and among the groups. Results There were 32 patients in the curettage adenoidectomy group and 33 patients in the microdebrider adenoidectomy group. Statistically significant differences were observed in the median tympanum pressure on the preoperative and 1st and 7th postoperative days for both the left and right ears with curettage adenoidectomy (p < 0.001, p < 0.001). This difference occurred on the 1st postoperative day, and the value returned to normal on the 7th day. There was no significant difference in the median tympanum pressure on the preoperative and 1st and 7th postoperative days for both the left and right ears in the microdebrider adenoidectomy group (p = 0.376, p = 0.128). Conclusion Postoperative Eustachian tube dysfunction is seen less often with the endoscopic-assisted microdebrider adenoidectomy technique than with the conventional adenoidectomy technique.

Resumo Introdução A adenoidectomia pode ser realizada de várias maneiras, inclusive por curetagem e por microdebridador, assistida por endoscopia. Essas duas técnicas têm algumas vantagens e desvantagens. Objetivo O objetivo deste estudo foi investigar os efeitos da técnica de adenoidectomia por curetagem e da adenoidectomia por microdebridador assistida por endoscopia sobre a pressão timpânica em pacientes pediátricos com hipertrofia adenoideana sem otite média com efusão. Método Estudo descritivo prospectivo feito com 65 pacientes que apresentavam membrana timpânica e timpanograma normais, que foram então submetidos à adenoidectomia ou adenotonsilectomia por hipertrofia adenoamigdaliana. Os pacientes foram divididos aleatoriamente em dois grupos: grupo adenoidectomia por curetagem e grupo adenoidectomia por microdebridador assistida por endoscópio. Todos os pacientes fizeram timpanometria e os valores das pressões do tímpano pré-operatórios e pós-operatórios no 1º e 7º dias foram comparados intragrupos e entre os grupos. Resultados Foram incluídos 32 pacientes no grupo adenoidectomia por curetagem e 33 pacientes no grupo adenoidectomia com microdebridador. Diferenças estatisticamente significantes foram observadas na mediana da diferença entre a pressão timpânica no pré-operatório e no 1º e 7º dias de pós-operatório para ambas as orelhas, direita e esquerda, na adenoidectomia por curetagem (p < 0,001, p < 0,001). Essa diferença ocorreu no 1º dia do pós-operatório e o valor retornou ao normal no 7º dia. Não houve diferença significante na mediana entre pressão timpânica no pré-operatório e no 1º e 7º dias de pós-operatório para as orelhas direita e esquerda no grupo de adenoidectomia com microdebridador (p = 0,376, p = 0,128). Conclusão A disfunção tubária no pós-operatório é observada menos frequentemente com a técnica de adenoidectomia por microdebridador assistida por endoscopia quando comparada com a técnica convencional.

Experiencia inicial en la adaptación del instrumental del tratamiento video asistido modificado de las fistulas perianales complejas (VAMAFT) / Initial experience in the adaptation of the instruments of the modified assisted video treatment of complex perianal fistulas (VAMAFT)

Introducción: Las fístulas perianales tienen dos problemas fundamentales, la tasa de recurrencia y de incontinencia fecal postoperatoria, complicaciones que varían en frecuencia dependiendo de varios factores como el tipo de fistula, la técnica quirúrgica usada y la experiencia del cirujano. Debido a esto existen técnicas quirúrgicas no conservadoras y conservadoras de esfínteres donde se incluye el tratamiento video asistido que aparece desde el año 2006 y en la cual se utiliza un sistema de video endoscopio sofisticado y de alto valor económico el cual hemos adaptado a nuestro medio. Pacientes y método: De septiembre del 2015 al 2017 en la Unidad de Coloproctología del Hospital Domingo Luciani IVSS se realizó un estudio prospectivo experimental, donde se incluyeron 18 pacientes con fístulas perianales complejas diagnosticadas previamente con Ecofistulografía 3D y los cuales se operaron con un sistema adaptado usando citoscopio pediátrico de 4 mm y energía láser. Se evaluaron parámetros referentes a la técnica así como la tasa de éxito y riesgo de incontinencia. Resultados: Tiempo quirúrgico de 40 a 80 minutos, con tasa de éxito de 89%, recidiva en 2 pacientes, con tiempo de seguimiento entre 12 a 36 meses y sin cambios en la escala de incontinencia pre y post quirúrgica. Conclusión: El tratamiento video asistido modificado para fistulas anales (VAMAFT) es una técnica innovadora y factible de realizar al adaptar algunos instrumentos, con una tasa de éxito adecuada y sin riesgo de incontinencia, pero más trabajos aleatorizados con mayor números de pacientes deben ser realizados.

Introduction: Anal fistulas have two basic problems, rate of recurrence and postoperative anal incontinence. These complications vary according to several factors such as type of anal fistula, surgical technique and the surgeon´s experience. For each cases there are different surgical techniques with and without conservation of anal sphincters like conservative video assisted anal fistula treatment, described in 2006, this technique uses a sophisticated and expensive endoscope system but that we modified to use in our hospitals. Patients and method: Between September 2015 to 2017 in the Unit of Coloproctology of Domingo Luciani Hospital, was perfomed a prospective and experimental trial in 18 patients with anal complex fistulas previously diagnosed using tridimensional anal ultrasound and operated with a modified system consisting of pediatric cystoscope of 4 mm and laser energy. Some parameters were evaluated including surgical technique, recurrence and anal incontinence rate. Results: Surgical times were between 40 to 80 minutes, success rate of 89%, recurrence in two patients with follow up of 12 to 36 months and no changes in pre and post surgical anal incontinence scale. Conclusion: Video assited modified anal fistula treatment (VAMAFT) is an innovative and feasible surgical technique to do adapting some instruments, with suitable success rate and without anal incontinence risk but many randomized research with more patients have to be perfomed.

Minimally invasive video-assisted mitral valve replacement with a right chest small incision in patients aged over 65 years

Abstract Objective: To analyze and summarize the clinical safety and feasibility of minimally invasive video-assisted mitral valve replacement via a right thoracic minimal incision in patients aged over 65 years. Methods: The clinical data of 45 patients over 65 years old who had mitral valve disease were analyzed retrospectively from January 2014 to January 2017 at Union Hospital, Fujian Medical University. The patients were divided into two groups; 20 patients in group A, who underwent minimally invasive video-assisted mitral valve replacement via a right thoracic minimal incision, and 25 patients in group B, who underwent conventional mitral valve replacement. We collected and analyzed their relevant clinical data. Results: The operation was completed successfully in both groups. Compared with group B, group A was clearly superior for postoperative analgesia time, postoperative hospital length of stay, thoracic drainage liquid, blood transfusion, and length of incision. There were no differences between the two groups in postoperative severe complications and mortality. More patients in group B had pulmonary infections and poor incision healing, while more patients in group A had postoperative pneumothorax and subcutaneous emphysema. Conclusion: In patients aged over 65 years, minimally invasive video-assisted mitral valve replacement with a small incision in the right chest had the same clinical safety and efficacy as the conventional method.

Adenoma paratiroideo ectópico resecado mediante videomediastinoscopia. A propósito de un caso / Parathyroid ectopic adenoma resected through videomediastinoscopy. A case report

Presentamos a una mujer de 44 años, con cólicos renoureterales de repetición. Durante su estudio, se detectan niveles de hormona paratiroidea (PTH) y calcio elevados, y litiasis renal, siendo el principal diagnóstico hiperparatiroidismo primario. La gammagrafía con Tecnecio Sestamibi (99m Tc MIBI) sugiere la existencia de glándula paratiroides patológica en el mediastino. En la tomografía computarizada (TC) se objetiva un nódulo compatible con adenoma paratiroideo. Se procedió a su resección mediante videomediastinoscopia. Las glándulas paratiroideas ectópicas se atribuyen a la migración anormal durante la embriógenesis; ocurren en un 15-20% de pacientes con hiperparatiroidismo. El hiperparatiroidismo debido a la actividad de estas glándulas ectópicas es infrecuente (entre el 1-8% de pacientes sometidos a cirugía de glándulas paratiroides). Su resección está indicada si existe hiperfunción glandular o complicaciones por hipercalcemia. Dada la escasa incidencia de esta patología, consideramos de interés su divulgación en la literatura médica

We present a 44-year-old woman with no history of interest, who presented recurrent renourelate colic. Elevated parathyroid hormone (PTH) and calcium levels were detected, as well as renal lithiasis. The main diagnosis was primary hyperparathyroidism. The scintigraphy with Technetium (99m Tc MIBI) Sestamibi suggested the existence of a pathological parathyroid gland in the mediastinum. A computed tomography (CT) scan revealed a nodule compatible with a parathyroid adenoma. We proceeded with its resection by videomediastinoscopy. The ectopic parathyroid glands are attributed to abnormal migration during embryogenesis; they occur in 15-20% of patients with hyperparathyroidism. Hyperparathyroidism caused by ectopic glands is infrequent (between 1-8% of patients undergoing surgery for parathyroid glands). Its resection is indicated if there is glandular hyperfunction or complications due to hypercalcemia. Given the low incidence of this pathology, we consider its report in the medical literature to be of interest

Initial experience of video endoscopic inguinal Lymphadenectomy in a center located at northeast brazilian region

ABSTRACT Introduction: Video endoscopic inguinal lymphadenectomy - VEIL - has emerged as an alternative to reduce post-surgical complications (PSC) in patients with penile cancer submitted to inguinal lymphadenectomy (IL). In some series, these PSC are observed in more than 50% of patients. The objectives of the present study are to describe the initial experience of VEIL in a Hospital in Teresina, PI, Brazil, and to analyze PSC incidence. Material and Methods: Retrospective descriptive study of patients submitted to VEIL from March 2014 to November 2015. Data were collected regarding surgical time, bleeding, complications, lymph node number, conversion, global complications, drainage time, cellulitis, lymphocele, cutaneous necrosis, miocutaneous necrosis and hospitalization time. Results: 20 lower limbs of 11 patients were operated. Mean age was 51.4 (24-72) years. Mean surgical time was 85 (60-120) minutes. No patient showed intrasurgical complications, bleeding > 50 mL or conversion. Three surgeries evolved with lower limb edema, 2 with lymphoceles and one patient had cutaneous necrosis and another bulging of surgical wound. Mean time of hospitalization was 4 (2-11) days. A mean of 5.8 (1-12) lymph nodes were dissected in each surgery. Conclusion: VEIL is a safe and easy technique with lower incidence of PSC that can be reproduced in small centers.
