Conclusions: Magnet-assisted single-port laparoscopic cholecystectomy under spinal anesthesia has shown effectiveness in significantly reducing postoperative pain after 6h, associated with significantly exceeding expectations in those operated on, without a significant increase in operative time or hospital stay.

Apendicectomía laparoscópica por puerto único versus técnica de tres puertos: estudio clínico aleatorizado / Single-port laparoscopic appendectomy versus three-port technique: a randomized clinical trial

Introducción: En la búsqueda de nuevas y mejores alternativas quirúrgicas que permitan disminuir el trauma a la pared abdominal, ha surgido la cirugía por puerto único (PU), un procedimiento que consiste en la realización de la cirugía laparoscópica a través de una incisión única, generalmente en la cicatriz umbilical. Los resultados han sido alentadores y nuevas investigaciones al respecto son necesarias. Objetivo: Comparar la técnica quirúrgica de la apendicectomía laparoscópica por puerto único (PU) versus técnica estándar de 03 puertos (AL3P) en el tratamiento de pacientes con apendicitis aguda. Metodología: Estudio prospectivo, aleatorizado, incluyó 158 pacientes distribuidos en 2 grupos (71 PU, 89 AL3P), desde junio de 2013 a junio de 2016, comparándose variables demográficas, tiempo quirúrgico, complicaciones trans y postoperatorias, conversión, dolor postoperatorio, beneficios estéticos y satisfacción. Resultados: La edad, sexo, IMC, evolución, medicación previa, recuento leucocitario y fase de la enfermedad fue similar en ambos grupos. El tiempo operatorio promedio en PU fue de 48 min, menor que en AL3P (p˂0,001), y se evidenció disminución del mismo posterior a la curva de aprendizaje de 30 casos. No hubo conversión en PU a cirugía abierta. La tasa de complicaciones intra Y postoperatorias fue similar en ambos grupos (p=0,486 y p=0,887). La estancia hospitalaria fue menor en los pacientes de PU (p˂0,001) con mejor resultado estético (p=0,036) y mayor grado de satisfacción (p=0,047). Conclusión: La apendicectomía por PU demostró ser una técnica factible, segura y reproducible en nuestro medio(AU)

Introduction: In the search for new and better surgical alternatives to reduce the trauma to the abdominal wall, it has emerged single port surgery (SP), a procedure that involves performing laparoscopic surgery through a single incision, usually in the umbilicus. The results have been encouraging and further investigations are needed in this regard. Objective: To compare laparoscopic single port appendectomy (SP) versus standard 03 ports laparoscopic technique (AL3P) in the treatment of patients with acute appendicitis. Materials and Methods: Prospective, randomized study, included 158 patients divided into 2 groups (71 SP, 89 AL3P), from June 2013 to June 2016, comparing demographic variables, surgical time, trans and postoperative complications, conversion, postoperative pain, aesthetic benefits and satisfaction. Results: Age, sex, BMI, evolution, premedication, white blood cell count and stage of the disease was similar in both groups. Mean operative time was 48 min on the SP, lower than in AL3P (p˂0,001), and decreased following the learning curve of 30 cases. There was no conversion of SP to open surgery. The rate of intraoperative and postoperative complications was similar in both groups (p = 0.486 and p = 0.887). The hospital stay was lower in patients SP (p˂0,001), with better cosmetic outcome (p = 0.036) and greater satisfaction (p=0.047). Conclusion: SP appendectomy proved to be a feasible, safe and reproducible technique in our environment(AU)

Cirugía laparoscópica por puerto único: ¿moda pasajera o un reto para el futuro? 10 años de experiencia.

La cirugía laparoscópica por puerto único es un concepto que refleja la expansión que están sufriendo las técnicas mínimamente invasivas en los últimos años. Pese a ser un estímulo para todo laparoscopista, su implantación es hoy por hoy una asignatura pendiente en la mayoría de los hospitales. Nuestro objetivo es reflexionar sobre la laparoscopia a través de incisión única a la luz de nuestra casuística. Hemos realizado un estudio descriptivo observacional retrospectivo de pacientes intervenidos en nuestro centro mediante laparoscopia a través de incisión única Desde 2012, se han realizado en nuestro hospital, 215 laparoscopias por puerto único de las cuales 175 son apendicectomías, 37 hemicolectomías derechas, 2 colecistectomías y 1 eventroplastia con buenos resultados clínicos y estéticos. La laparoscopia por incisión única supone un paso más en el perfeccionamiento de la cirugía mínimamente invasiva y debe suponer un reto y un empeño para el cirujano su expansión e implantación.

Single-port laparoscopic surgery is a concept that reflects the expansion of minimally invasive techniques in recent years. Despite being a stimulus for every laparoscopist, its implementation is still a pending subject in most hospitals. Our objective is to reflect on single incision laparoscopy in the light of our casuistry. We have performed a retrospective observational descriptive study of patients operated in our center by single incision laparoscopy. Since 2012, 215 single port laparoscopies have been performed in our hospital of which 175 are appendectomies, 37 right hemicolectomies, 2 cholecystectomies and 1 eventroplasty with good clinical and aesthetic results. Single incision laparoscopy is a further step in the improvement of minimally invasive surgery and should be a challenge and a commitment for the surgeon in its expansion and implementation.

Suprarrenalectomía retroperitoneoscópica por puerto único: experiencia inicial y estandarización de la técnica / Single-port retroperitoneoscopic adrenalectomy: Initial experience and standardization of the technique

Introducción y objetivo: El abordaje mediante cirugía mínimamente invasiva de la patología de la glándula suprarrenal es el más extendido hoy en día, en donde la retroperitoneoscopia ocupa un lugar a tener muy en cuenta; sin embargo, la evolución de estas técnicas hacia abordajes todavía menos invasivos a través de puerto único es anecdótica.La finalidad de este trabajo es describir nuestra experiencia inicial en cirugía retroperitoneoscópica por puerto único (SPORS) de la glándula suprarrenal centrándonos en los datos perioperatorios y dolor postoperatorio.Material y métodosRecogimos y analizamos los datos demográficos y operatorios de una serie de pacientes tratados mediante suprarrenalectomía mediante SPORS. Todos los procedimientos se realizaron mediante una única incisión subcostal de 3-4cm a través de un puerto multicanal. Se recogen diferentes datos quirúrgicos como tiempo operatorio, sangrado, estancia o presencia de complicaciones. Empleamos la escala visual analógica (EVA) para la valoración del dolor postoperatorio.ResultadosEntre diciembre del 2018 y agosto del 2020, 6 pacientes con diferentes patologías suprarrenales fueron intervenidos en nuestro Departamento de forma consecutiva por el mismo cirujano mediante SPORS. Todas las cirugías se realizaron sin requerir colocación de trocares accesorios o reconversión a cirugía abierta. El tiempo medio de las intervenciones fue de 91,6±16,3 min, con un sangrado <150ml, una estancia media de 35,8±13,3 h y un dolor postoperatorio analizado EVA ≤ 3 (mediana de 0,5). El tamaño medio de las piezas fue de 57,8±18mm. No se reportó ninguna complicación según la escala Clavien-Dindo.

Introduction and objective: The minimally invasive surgical approach to adrenal gland pathology is the most widely used nowadays, and retroperitoneoscopy occupies a relevant place. However, the evolution of these techniques towards even less invasive surgery through single-port access is anecdotal. The aim of this work is to describe our initial experience in single-port retroperitoneoscopic surgery (SPORS) of the adrenal gland focusing on perioperative data and postoperative pain.Material and methodsWe collected and analyzed the demographic and operative data of a series of patients undergoing adrenalectomy through SPORS. All procedures were performed through a single 3-4cm subcostal incision with a multichannel port. Surgical data such as operative time, bleeding, length of stay and presence of complications were collected. We used the visual analog scale (VAS) for postoperative pain assessment.ResultsFrom December 2018 to August 2020, 6 patients with different types of adrenal pathology underwent consecutive surgeries in our Department by the same surgeon using SPORS. All surgeries were performed without requiring accessory trocar placement or reconversion to open surgery. The mean operative time was 91.6±16.3minutes, with <150mL bleeding, mean length of stay of 35.8±13.3hours and postoperative pain of VAS ≤3 (median 0.5). The mean size of specimens was 57.8±18mm. No complications were reported according to the Clavien-Dindo scale. (AU)

Minimizing minimally invasive surgery: Current status of the single-port robotic surgery in Urology.

BACKGROUND: The novel da Vinci Single-Port (SP) robotic platform received the US FDA approval in 2018. The device, specifically conceived for single-site approach, is pushing through the limits of minimally invasive surgery. We sought to provide a comprehensive overview of the current status of the clinical experiences accomplished by the da Vinci SP in urology, and to discuss future perspectives. METHODS: A non-systematic literature review was performed focusing on single port articles in urological surgery using Medline/PubMed and Embase search electronic engines. The authors analyzed findings and a brief report of the clinical experience for surgical procedures completed by the SP platform was described. RESULTS: The current data available from single-port robotic established the safety and feasibility of urologic procedures using this novel platform. However, the results come from single-center case series, small cohorts and retrospective studies that need to be cautiously interpreted. Additional evidence is required to determine the asset of the SP platform in the urological community. CONCLUSIONS: The SP robotic system opens new frontiers on the surgical scenery facilitating the completion of urological surgeries through a single incision. Further comparative studies will be required to assess perioperative and long-term oncological and functional outcomes among SP, multi-arm robotic and open approaches.

Objective: The objective of this study is to compare conventional laparoscopy with transumbilical single-port access for the surgical treatment of endometrial cancer. Materials and methods: A retrospective study was performed with 36 patients, of whom 18 were operated using conventional laparoscopy, and 18 using a transumbilical single-port access (laparoendoscopic single-site surgery, or LESS) by making a single incision in the umbilical skin of 2-3cm, and 3 incisions in the fascia. One 10-mm trocar and two 5-mm trocars were inserted next to each other to access the abdominal cavity. Results: There were no statistical differences between groups in postoperative changes in haemoglobin concentration (1.15 vs. 1.25g/dL, P=1), hospital stay (2.5 vs. 2.5 days, P=.69), intraoperative complication rate (0% vs. 5%, P=.19), postoperative complications (16.6% vs. 11.1%, P=.63), number of pelvic lymph nodes (16.5 vs. 18, P=.78), and number of para-aortic lymph nodes (9 vs. 10, P=.64). Patients in the LESS group experienced less postoperative pain (22.3% vs. 83.3%, P<.001), and had a higher rate of satisfaction with the cosmetic results (10 vs. 8, P=.001). The median operating time was lower in the LESS group (120-180min, P=.027). Conclusion: Laparoendoscopic single-site surgery is a feasible, safety and effective technique for the treatment of endometrial cancer, with less postoperative pain and better cosmetic results.(AU)

Apendicectomía laparoscópica unipuerto: primer caso reportado en Hospital Regional Rafael Hernández

La apendicitis aguda es una de las principales causas de emergencia quirúrgica. Su pico de incidencia se ubica entre la segunda y tercera década de la vida con un riesgo de 8.6% y 6.5% para hombres y mujeres, respectivamente. La historia clínica y el examen físico continúan siendo los pilares del abordaje diagnóstico, aunado a la utilización de estudios de imagen en los casos de duda. La apendicectomía laparoscópica es considerada como el "estándar de oro" para el manejo de esta condición. La variante unipuerto de este procedimiento fue realizada por primera vez en 1992 por Pelosi, ofreciendo los mismos beneficios que la modalidad multipuertos, con la ventaja de menor cantidad de incisiones. Se presenta caso de paciente masculino de 52 años con cuadro clínico altamente sugestivo de apendicitis aguda y antecedente de hernia umbilical, el cual es sometido a la primera apendicectomía laparoscópica unipuerto reportada en nuestra institución y dado de egreso en su primer día post-operatorio sin complicaciones.

Single port endoscopic mastectomy: surgical technique and first case in Mexico.

Las innovaciones técnicas han permitido realizar un sinnúmero de cirugías endoscópicas y laparoscópicas, entre ellas la mastectomía preservadora de piel y pezón por puerto único, que ha sido reportada como bien tolerada, con un excelente resultado cosmético y con el mismo pronóstico oncológico que la cirugía tradicional. Esta técnica, común en Asia, presenta diversos retos técnicos y económicos. Presentamos la primera aproximación en nuestro país sobre este abordaje en una paciente con cáncer de mama. Para realizar esta cirugía es preciso el entrenamiento en mínima invasión y en cirugía mamaria, así como una adecuada selección de las pacientes.Technical innovations and scientific advances have allowed to perform countless endoscopic and laparoscopic surgical procedures. Among these, Single port endoscopic Mastectomy has been reported as well tolerated, with great aesthetic results and the same oncologic prognosis as traditional surgery. This popular approach in Asian countries presents many technical and economic challenges. We present the first endoscopic approach in our country: a female patient with infiltrating ductal carcinoma in the left breast. We understand that to carry out this procedure, adequate patient selection, great minimal invasive and breast surgery skills are necessary.

Multiquadrant Combined Robotic Radical Prostatectomy And Left Partial Nephrectomy: A Combined procedure by A Single Approach. / Cirugía robótica multicuadrante concomitante para prostatectomía radical y nefrectomía parcial izquierda. Dos procedimientos mediante un solo abordaje.

INTRODUCTION: To present the first case of a concomitant robotic radical prostatectomy and a left robotic partial nephrectomy performed by a single-port approach using the SP® da Vinci surgical system (Intuitive Surgical, Sunnyvale CA, EE.UU.). PATIENT AND METHODS: A 66-year-old male diagnosed with localized prostate cancer and a left kidney renal mass incidentally found on computed tomography (CT) scan during prostate cancer evaluation. Procedures were performed using a single supra-umbilical 3cm incision, plus one additional laparoscopic port, utilizing a standard Gelpoint® (Applied Medical, Rancho Santa Margarita, CA, EE.UU.) and replicating the technique previously described for single-port transperitoneal radical prostatectomy and partial nephrectomy with the use of the SP® robotic platform. RESULTS: Total operative time was 256minutes (min) with a console time of 108min for radical prostatectomy, and 101min for the partial nephrectomy respectively, including a warm ischemia time of 26min. Estimated blood loss was 250cc. Blood transfusion was not needed. Final pathology for prostate was adenocarcinoma Gleason 7 (4+3) and for the kidney lesion was renal cell carcinoma. After two months of follow-up, PSA was undetectable and no complications or recurrence were detected. CONCLUSIONS: The single-port approach has advantages as easier surgical planning and transition for combined and multi-quadrants surgeries: faster recovery, minimal postoperative pain and need for opioids, and excellent cosmetic outcome. We suggest that combined procedures should be performed only in high volume institutions by surgeons with vast experience in robotic surgery in selected patients.

MATERIAL AND METHODS: We performed 5 single-port robot-assisted surgeries (R-LESS) between May and October 2014. We performed 3 ureteral reimplant surgeries, one ureteropyeloplasty in an inverted kidney and 1 partial nephrectomy. The perioperative and postoperative results were collected, as well as a report of the complications according to the Clavien classification system. RESULTS: Of the 5 procedures, 4 were performed completely by LESS, while 1 procedure was reconverted to multiport robot-assisted surgery. There were no intraoperative complications. We observed perioperative complications in 4 patients, all of which were grade 1 or 2. The mean surgical time was 262minutes (range, 230-300). DISCUSSION: In our initial experience with the da Vinci device, R-LESS surgery was feasible and safe. There are still a number of limitations in its use, which require new and improved R-LESS platforms.

Outcomes of laparoscopic adrenalectomy Conventional technique versus laparo-endoscopic single-site surgery. / Resultados de la suprarrenalectomía laparoscópica: técnica convencional vs puerto único laparoscópico.

OBJECTIVE: Perform a comparative analysis of the outcomes of conventional laparoscopic adrenalectomy (LC) and the newly introduced laparo-endoscopic single-site surgery (LESS) over ten years. MATERIAL AND METHOD: We retrospectively reviewed the experience of a single surgeon from our medical centre with laparoscopic adrenalectomy, either through LC or LESS, with 75 patients between August 2005 and June 2015. Here we describe: age, sex, size, lateralization, preoperative diagnosis, total operating time, intraoperative bleeding, conversion to open surgery, mean hospital stay, intra- and postoperative complications and histopathology report. We used Fischer's and the Chi-squared tests to compare categorical data and Student's T-test for a comparison of the means with a normal distribution. Statistical significance was determined when p<0.05. RESULTS: LC was performed in 51 patients, and LESS in 24 patients. No statistical significance was found for total operating time (LC: 103.9±13.21min vs. LESS: 101.46±13.65min; p=0.07), estimated bleeding (LC: 258.82±136.92cc vs. LESS: 131,25±36,74cc; p=0.46), intraoperative complications (5 cases in LC, none in LESS; p=0.47), nor for postoperative complications (two in LC vs. one in LESS; p=0.69), as catalogued according to the modified Clavien classification system. We detected a statistical significance difference in the comparisons of the mean hospital stay, which was reduced in LESS (LC: 3.55±0.69 days vs. LESS: 2.21±0.31 days; p=0.01). CONCLUSIONS: Adrenalectomy with LC is the approach of choice for surgical treatment of adrenal pathologies. The LESS technique is safe, improves the cosmetic results, and does not increase mortality if performed by experienced teams.

Apendicitis aguda. Estudio comparativo entre puerto único, laparoscopia convencional versus laparotomía / Acute appendicitis. Comparative study of single port, conventional laparoscopic versus laparotomy

Objetivo:Comparar las tres técnicas de abordaje para la apendicectomía: puerto único (APU), laparoscopia convencional (ALC) y laparotomía (AL) en pacientes con diagnóstico de apendicitis aguda. Métodos: se realizó AL por incisión de McBurney, ALC por tres puertos y APU. Para las cirugías por APU y ALC se utilizó pinza de LigaSure AtlasTM 37cms Hand de 10mm (Covidien®) para ligar el mesoapéndice, sutura crómico catgut® 0 o endoloop®para ligar la base de la apéndice, en abierta o laparoscopica, respectivamente. Para la APU se utilizó el SILS Port™ (Covidien®). Se realizó un estudio comparativo, prospectivo, monocéntrico, entre abril 2014 y octubre 2014, en pacientes con diagnóstico de apendicitis aguda en el Hospital General del Este "Dr. Domingo Luciani"y que cumplieron los criterios de inclusión. Resultados: Se realizaron 58 apendicectomías, 20 AL, 20 ALC y 18 APU. El tiempo quirúrgico y la estancia hospitalaria fueron menores en las ALC con promedio de 47 minutos y 33,6 horas, respectivamente. La incidencia de complicaciones intraoperatorias y postoperatorias fueron mayores el las AL estableciéndose una relación estadística-mente significativa entre la técnica quirúrgica y la infección del sitio operatorio (p < 0,05). La técnica quirúrgica influye en la manifestación de dolor en las primeras 08 horas de postoperatorio (p < 0,05). Conclusión: La decisión del abordaje quirúrgico será determinado por la experiencia del cirujano y la disponibilidad del instrumental quirúrgico, sin embargo, la evidencia actual sugiere que la ALC debe ser considerada como primera elección(AU)

Objective: To compare the three techniques approach appendectomy: single port (SPA), conventional laparoscopy (CLA) and laparotomy (LA) in patients with acute appendicitis. Methods: LA was performed by McBurney incision, CLA was performed with three ports and SPA. LigaSure clamp 10mm Hand AtlasTM 37cms (Covidien®) was used to cut the mesoappendix, chromic suture catgut® 0 or endoloop® to ensure the base of the appendix, in open or laparoscopic, respectively. The SILS™ Port (Covidien®) was used for the SPA. A comparative, prospective, single-center study was conducted between April 2014 and October 2014, in patients with a diagnosis of acute appendicitis in East General Hospital "Dr.Domingo Luciani" and who met the inclusion criteria. Results: 58 appendectomies, 20 LA, 20 CLA and 18 SPA were performed. The operative time and hospital stay were lower in the CLA average of 47 minutes and 33.6 hours, respectively. The incidence of intraoperative and postoperative complications were higher on the LA establishing a statistically significant relationship between surgical technique and surgical site infection (p <0.05). The surgical technique influences the manifestation of pain in the first 08 hours postoperatively (p <0.05). Conclusion: The decision of surgical approach will be determined by the surgeon's experience and availability of surgical instruments, however, current evidence suggests that CLA should be considered as first choice(AU)

[Drainage of amoebic liver abscess by single incision laparoscopic surgery. Report of a case]. / Drenaje de absceso hepático amebiano por laparoscopia de puerto único. Reporte de un caso.

BACKGROUND: Single incision laparoscopic surgery has increased recently due to successful results, achieved in several procedures. The aim of the present work is to present the first case in which single incision laparoscopy is used for the drainage of an amoebic liver abscess. CLINICAL CASE: A 44-year-old man presented with intense right upper quadrant pain, generalised jaundice, tachycardia, fever, hepatomegaly and a positive Murphy's sign. Laboratory results revealed an increased plasma bilirubin, elevated alkaline phosphatase and transaminases, leucocytosis, negative viral panel for hepatitis, and positive antibodies against Entamoeba histolytica. On an abdominal computed tomography a 15 × 12.1 cm hypodense lesion was observed in the patient's liver, identified as an amoebic liver abscess. Analgesics and antibiotics were started and subsequently the patient was submitted to laparoscopic drainage of the abscess using a single port approach. Drainage and irrigation of the abscess was performed. Four days later the patient was discharged without complications. CONCLUSION: Management of amoebic liver abscess is focused on the elimination of the infectious agent and obliteration of the abscess cavity in order to prevent its complications, especially rupture. Laparoscopic surgery has proved to be a safe and effective way to manage this entity.

Umbilical laparoendoscopic partial cystectomy.

OBJECTIVE: To present our center's experience in single-port umbilical laparoendoscopic partial cystectomies, in both benign and malignant pathologies. Patient characteristics, perioperative aspects and the surgical techniques used are reviewed. MATERIAL AND METHOD: Since May 2012, five patients have undergone a transumbilical single-port laparoendoscopic partial cystectomy with curved equipment through a reusable multichannel system and a 3.5mm accessory trocar. Patients were three males and two females aged between 28 and 78 (median: 44±42.5) years. The etiologies were endometriosis (in 2 cases), a tumor in the diverticulum, a congenital bladder diverticulum and ureterocele (1 case of each). RESULTS: Median surgery time was 273±163.4minutes, and intraoperative bleeding 250±175ml. None of the patients required transfusion. The postoperative period was uneventful, with good results and no complications. The hospital stay was 3±1 days. With monitoring of 20±17.5 months, morphological and functional recovery in the bladder and ureter was confirmed in all cases and the patient with neoplastic disease was disease-free more than 2 years after the surgery. CONCLUSIONS: An umbilical laparoendoscopic partial cystectomy represents a viable surgical option and ensures that excellent surgical and cosmetic results are achieved.
