Laparoscopic ventral onlay ureteroplasty with buccal mucosa graft for complex proximal ureteral stricture

ABSTRACT Introduction: There is lack of papers dedicated to the laparoscopic buccal mucosa graft (BMG) ureteroplasty of the complex upper ureteral stricture. The aim of this study is to evaluate the results of laparoscopic BMG ureteroplasty in patients with complex proximal ureteral stricture. Material and methods: Twenty-four patients underwent laparoscopic ventral onlay BMG ureteroplasty for long or recurrent proximal ureteral stricture not amenable to uretero-ureteral anastomosis over 2019-2022. Patient demographics, operative time, estimated blood loss, length of stay, follow-up, intra- and postoperative complication rate and percentage of stricture-free at last visit were analyzed. Results: The mean stricture length was 3.6 cm. The mean operative time was 208.3 min, while mean blood loss was 75.8 mL. The length of hospital stay was 7.3 days. No intraoperative complications were observed. Postoperatively, seven patients developed complications (29.2%). Five patients experienced a Grade II (according to Clavien nomenclature). Two patients developed a Grade IIIa complication, which included leakage of the anastomosis site. The mean follow-up was on the 22 months with stricture free rate 87.5%. Conclusion: Patients with proximal ureteral strictures could be effectively treated by laparoscopic ventral onlay ureteroplasty with a buccal mucosa graft.

Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer

ABSTRACT 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.

Impacto de la cardiomiotomía laparoscópica de Heller en la función del esfínter esofágico inferior y el diámetro del esófago / Impact of laparoscopic Heller cardiomyotomy on lower esophageal sphincter function and esophageal diameter

Introducción. La acalasia es un trastorno motor del esófago caracterizado por la ausencia de peristalsis y la alteración en la relajación del esfínter esofágico inferior. La cardiomiotomía laparoscópica de Heller más funduplicatura parcial es el tratamiento estándar. La mejoría sintomática ha sido bien documentada, pero no hay suficiente información objetiva respecto a los cambios fisiológicos y radiográficos luego del procedimiento. Métodos. Estudio de cohorte bidireccional de pacientes llevados a cardiomiotomía laparoscópica de Heller, entre los años 2018 y 2021, en el Hospital Universitario San Vicente Fundación de Medellín, Colombia. Se describen variables demográficas y clínicas. Se realizaron puntaje sintomático de Eckardt, manometría esofágica y radiografía de esófago en el pre y postoperatorio. Se hizo comparación de síntomas, presión basal del esfínter esofágico inferior, presión de relajación integrada y diámetro del esófago antes y después de la intervención. Resultados. Se incluyeron 24 pacientes. El 63 % fueron mujeres y la edad promedio fue de 44 años. Los valores promedio preoperatorios vs postoperatorios fueron: puntaje de Eckardt 10,6 vs 1,4 puntos (p<0,001), presión basal de 41,4 vs 18,1 mmHg (p=0,004) y presión de relajación integrada de 28,6 vs 12,5 mmHg (p=0,001). El diámetro del esófago no presentó cambios. No hubo correlación de síntomas con los cambios de presión del esfínter esofágico inferior. El tiempo de seguimiento fue de 20 meses. Conclusiones. La cardiomiotomía de Heller es un procedimiento altamente efectivo para el tratamiento definitivo de la acalasia, logrando una mejoría subjetiva y objetiva basada en síntomas y en parámetros de manometría, respectivamente

Introduction. Achalasia is a motor disorder of the esophagus characterized by the absence of peristalsis and impaired relaxation of the lower esophageal sphincter. Laparoscopic Heller ́s cardiomyotomy plus partial fundoplication is the standard treatment. Symptomatic improvement has been well documented, but there is insufficient objective information regarding physiologic and radiographic changes after the procedure. Methods. Bidirectional cohort study of patients underwent laparoscopic Heller ́s cardiomyotomy between 2018 and 2021 at the San Vicente Fundación University Hospital in Medellín, Colombia. Demographic and clinical variables are described. Eckardt symptom score, esophageal manometry, and esophageal radiography were performed pre and postoperatively. A comparison of symptoms, baseline lower esophageal sphincter pressure, integrated relaxation pressure, and esophageal diameter before and after intervention were performed.Results. 24 patients were included. 63% were women and the average age was 44 years. The preoperative vs. postoperative mean values were: Eckardt score 10.6 vs. 1.4 points (p<0.001), basal pressure of 41.4 vs. 18.1 mmHg (p=0.004) and integrated relaxation pressure of 28.6 vs. 12.5 mmHg (p=0.001). The diameter of the esophagus did not present changes. There was no correlation of symptoms with lower esophageal sphincter pressure changes. The follow-up time was 20 months. Conclusions. Heller cardiomyotomy is a highly effective procedure for the definitive treatment of achalasia, achieving subjective and objective improvements, based on symptoms and manometry parameters, respectively

Introducción. Los pacientes con antecedente de baipás gástrico que presentan coledocolitiasis no pueden ser tratados con la técnica convencional de colangiopancreatografía retrógrada endoscópica. En estos casos, la vía transgástrica abierta o asistida por laparoscopia, se convierte en una excelente alternativa a la exploración abierta de la vía biliar. Métodos. Estudio retrospectivo que incluyó pacientes adultos con coledocolitiasis y antecedente de gastrectomía subtotal o baipás gástrico con Y de Roux, llevados a colangiopancreatografía endoscópica transgástrica laparo-asistida, entre enero de 2019 y diciembre de 2021, en la Clínica CES de Medellín, Colombia. Resultados. Se encontraron siete pacientes, todos con antecedente de baipás gástrico para el manejo de la obesidad. La tasa de identificación y canulación de la vía biliar y extracción de cálculos fue del 100 % mediante el abordaje transgástrico laparo-asistido. Conclusión. De acuerdo con varias revisiones sistemáticas, esta técnica es relativamente fácil de implementar y segura, presentando una tasa de complicaciones inferior a 5 %. Se propone una variante de esta técnica

Introduction. Patients with a history of gastric bypass who present with choledocholithiasis cannot be treated with the conventional technique of endoscopic retrograde cholangiopancreatography. In these cases, the open or laparoscopic-assisted transgastric approach becomes an excellent alternative to open bile duct gastric exploration. Methods. A retrospective review of patients with choledocholithiasis and a history of subtotal gastrectomy or gastric bypass with Roux-en-Y, who underwent laparo-assisted transgastric endoscopic cholangiopancreatography, was conducted between January 2019 and December 2021 at Clínica CES de Medellín, Colombia. Results. Seven patients were found, all with a history of gastric bypass secondary to obesity. The rate of bile duct identification and cannulation, and stone removal was 100% using the laparo-assisted transgastric approach. Conclusion. According to several systematic reviews, this technique is relatively easy to implement and safe, presenting a rate of complications less than 5%. A variant to this technique is proposed

Introducción. El trasplante es la mejor opción de tratamiento para los pacientes con enfermedad renal terminal, sin embargo, existe discrepancia entre las listas de espera y la disponibilidad de órganos a partir de la donación cadavérica. Buscando aumentar el número de órganos disponibles se implementó el trasplante con donante vivo. A partir de la introducción de técnicas mínimamente invasivas para la nefrectomía, el donante vivo ha logrado cifras cercanas al 50 % de los trasplantes realizados en muchas instituciones, debido a los beneficios propios del procedimiento. El objetivo de este estudio fue describir los resultados después de la incorporación del procedimiento totalmente laparoscópico en nuestra institución. Métodos. Se hizo un análisis retrospectivo de las características de los pacientes llevados a nefrectomía para obtención de injerto por técnica totalmente laparoscópica y los resultados en un solo centro en Cali, Colombia, desde noviembre de 2019 hasta octubre de 2022. Los datos fueron obtenidos mediante la revisión de las historias clínicas electrónicas. Resultados. Se realizaron 78 nefrectomías para obtención de injerto con técnica totalmente laparoscópica. El tiempo operatorio promedio fue de 152 minutos, el sangrado promedio fue de 12 ml, la estancia hospitalaria promedio del donante fue de 2,8 días. La tasa de complicaciones fue de 7,6 % (4 pacientes con complicación Clavien-Dindo I y 2 pacientes Clavien-Dindo IIIb). No se presentó ningún caso de mortalidad. Conclusiones. La técnica totalmente laparoscópica resulta ser una técnica segura con baja tasa de morbilidad y excelentes beneficios para los donantes.

Introduction. Kidney transplant is the best treatment option for end-stage renal disease. However, the discrepancy between waiting lists and the availability of organs from cadaveric donation is well known. Organ transplantation with a living donor was implemented to increase the number of organs available. Since the introduction of minimally invasive techniques for nephrectomy, living donors have achieved figures close to 50% of transplants performed in many institutions due to the procedure's benefits. In our country, the experiences described are from the hand-assisted technique. This is the first description after incorporating the laparoscopic procedure. Methods. A retrospective analysis of the characteristics and results of all patients undergoing nephrectomy to obtain a graft using a laparoscopic technique was carried at a single center in Cali, Colombia, from November 2019 to October 2022. The electronic medical records were reviewed to obtain the data. Results. Seventy-eight nephrectomies were performed to obtain a graft with a laparoscopic technique. The mean operating time was 152 minutes, the average bleeding was 12 cc, and the average hospital stay was 2.8 days. The complication rate was 7.6% (four patients with Clavien-Dindo I complication and two Clavien-Dindo IIIb patients). There were no cases of mortality. Conclusions. The laparoscopic technique is safe, with a low morbidity rate and excellent benefits.

Laparoscopic pyeloplasty proficiency during a residency program after adoption of a standardized simulation training program is maintained during the COVID pandemic despite reduced surgery volume

ABSTRACT Purpose: To evaluate the effect of the standardized laparoscopic simulation training program in pyeloplasty, following its implementation and during the COVID-19 pandemic. Material and Methods: A retrospective chart review was performed at Hospital de Clínicas de Porto Alegre, a tertiary referral center in south Brazil, in which 151 patients underwent laparoscopic pyeloplasty performed by residents between 2006-2021. They were divided into three groups: before and after adoption of a standardized laparoscopic simulation training program and during the COVID-19 pandemic. The main outcome was a combined negative outcome of conversion to open surgery, major postoperative complications (Clavien-Dindo III or higher) or unsuccessful procedure, defined as need for redo pyeloplasty. Results: There was a significant reduction in the combined negative outcome (21.1% vs 6.3%), surgical time (mean 200.0 min vs 177.4 min) and length of stay (median 5 days vs 3 days) after the adoption of simulation training program. These results were maintained during the COVID-19 pandemic (combined negative outcome of 6.3%, mean surgical time of 160.1 min and median length of stay of 3 days) despite a reduction in 55.4% of the surgical volume. Conclusion: A structured laparoscopic simulation program can improve outcomes of laparoscopic pyeloplasty during the learning curve.

Importancia del conocimiento anatómico del espacio extraperitoneal y su utilidad en los abordajes quirúrgicos / Importance of anatomical knowledge of the extraperitoneal space and its usefulness in surgical approaches

Introducción. El espacio extraperitoneal, se define como el segmento topográfico ubicado entre el peritoneo parietal internamente y la fascia transversalis externamente. Como resultado del desarrollo y consolidación de la cirugía laparoscópica, en particular de la herniorrafia inguinal por esta vía, se ha presentado un renovado y creciente interés en esta área anatómica, debido a la importancia de su conocimiento detallado en la cirugía de mínima invasión. Métodos. Se hizo una revisión narrativa de la literatura para presentar una información actualizada y detallada sobre la anatomía del espacio extraperitoneal y su importancia en diferentes procedimientos quirúrgicos realizados actualmente. Resultados. Por fuera del espacio peritoneal, se encuentran las áreas anatómicas externas al peritoneo parietal, que incluyen la preperitoneal y la retroperitoneal. Mediante la laparoscopia, se pueden localizar en estos espacios cinco triángulos anatómicos, además de la corona mortis y el triángulo supra vesical. Conclusión. El conocimiento del espacio extraperitoneal es de gran importancia para el cirujano general, teniendo en cuenta los múltiples procedimientos que requieren el abordaje de esta área topográfica

Introduction. The extraperitoneal space is defined as the topographic segment located between the parietal peritoneum internally and the fascia transversalis externally. As a result of the development and consolidation of laparoscopic surgery, particularly inguinal herniorrhaphy by this route, there has been a renewed and growing interest in this anatomical area, due to the importance of its detailed knowledge in minimally invasive surgery. Methods. A narrative review of the literature was made to present updated and detailed information on the anatomy of the extraperitoneal space and its importance in different surgical procedures currently performed. Results. Outside the peritoneal space are the anatomical areas external to the parietal peritoneum, including the preperitoneal and extraperitoneal. Using laparoscopy, five anatomical triangles, in addition to the corona mortis and the supravesical triangle, can be located in these spaces. Conclusion. Knowledge of the extraperitoneal space is of great importance for the general surgeon, taking into account the multiple procedures that require the approach of this topographic area

Evaluation of Laparoscopic Management of Adnexal Mass- An Observational Study in a Tertiary Care Hospital

Background: Adnexal masses are of increasing distress among women because of high fatality related to ovarian malignancy. Finding masses at the primary stage is of crucial significance and in these cases, adnexal masses could be dangerous. Laparoscopy has seemed as one of the most feasible surgical procedures and is now recommended as the “gold standard” method for the management of a wide range of gynecological complaints. The study aimed to determine the evaluation of laparoscopic management of adnexal mass. Material & Methods: A prospective observational study was carried out in the Department of Gynecology & Obstetrics, Ibn Sina Medical College and Hospital, Kallyanpur, Dhaka from 1st January 2020 to July 2022. A total of 146 patients (N=146) were enrolled in this study. Data were collected using the predesigned semi-structured questionnaire. Verbal consent was taken before recruiting the study population. Completed data forms were reviewed, edited, and processed for computer data entry. The data analysis was performed using Statistical Package for the Social Sciences (SPSS) Version 25.0. Results: Among the study population (N=146), the majority of the patients (70,48.0%) belonged to 21-30 years old. Most of the patients (124, 85.0%) were of the reproductive age group & only five patients (5, 3.4%) were of postmenstrual age. Most of the patients (38,26.0%) had ectopic mass, and around one-fourth of the patients (35,24.0%) had a simple cyst. around two-fifths of the patients (63,43.1%) underwent ovarian cystectomy, one-fourth of the patients (37,25.3%) underwent salpingectomy, twenty patients (20,13.7%) underwent excision of chocolate cyst, fourteen patients (14,9.6%) underwent salpingo-oophorectomy and two patients (2,1.4%) underwent conversion to laparotomy. Postoperative fever was seen in only three patients (3,2.0%), and minor port-site infection was seen in three patients (3,2.0%). Conclusion: The diagnosis of adnexal masses is indispensable which may upset all age groups of women. The laparoscopic method is an operative and innocuous procedure for managing patients with adnexal masses. An adequate selection of cases, a laparoscopic surgery-based hospital, and a proficient laparoscopic surgical team are vigorous for good patient consequences.

Laparoscopic evaluation of female genital tuberculosis in infertility: An observational study

Background & objectives: Female genital tuberculosis (FGTB) is an important variety of extrapulmonary TB causing significant morbidity, especially infertility, in developing countries like India. The aim of this study was to evaluate the laparoscopic findings of the FGTB. Methods: This was a cross-sectional study on 374 cases of diagnostic laparoscopy performed on FGTB cases with infertility. All patients underwent history taking and clinical examination and endometrial sampling/biopsy for acid-fast bacilli, microscopy, culture, PCR, GeneXpert (only last 167 cases) and histopathological evidence of epithelioid granuloma. Diagnostic laparoscopy was performed in all the cases to evaluate the findings of FGTB. Results: Mean age, parity, body mass index and duration of infertility were 27.5 yr, 0.29, 22.6 kg/m2 and 3.78 years, respectively. Primary infertility was found in 81 per cent and secondary infertility in 18.18 per cent of cases. Endometrial biopsy was positive for AFB microscopy in 4.8 per cent, culture in 6.4 per cent and epithelioid granuloma in 15.5 per cent. Positive peritoneal biopsy granuloma was seen in 5.88 per cent, PCR in 314 (83.95%) and GeneXpert in 31 (18.56%, out of last 167 cases) cases. Definite findings of FGTB were seen in 164 (43.86%) cases with beaded tubes (12.29%), tubercles (32.88%) and caseous nodules (14.96%). Probable findings of FGTB were seen in 210 (56.14%) cases with pelvic adhesions (23.52%), perihepatic adhesions (47.86%), shaggy areas (11.7%), pelvic adhesions (11.71%), encysted ascites (10.42%) and frozen pelvis in 3.7 per cent of cases. Interpretation & conclusions: The finding of this study suggests that laparoscopy is a useful modality to diagnose FGTB with a higher pickup rate of cases. Hence it should be included as a part of composite reference standard.

Escisión meso-rectal total por vía trans anal (TaTME). Experiencia institucional / Trans anal total meso-rectal excision (TaTME). Institutional experience

Introducción. La cirugía es la base del tratamiento curativo del cáncer de recto. La escisión meso-rectal total ha permitido mejorar los desenlaces oncológicos, disminuyendo las tasas de recurrencia locorregional e impactando en la supervivencia global. El empleo de esta técnica en los tumores de recto medio o distal es un reto quirúrgico, en el que la vía trans anal, permite superar las dificultades técnicas. Método. Se realizó un estudio observacional retrospectivo, recolectando la información de los pacientes con cáncer de recto medio y distal llevados a cirugía con esta técnica, en dos instituciones de cuarto nivel en Medellín, Colombia, entre enero de 2017 y marzo de 2022. Se analizaron sus características demográficas, la morbilidad perioperatoria y la pieza quirúrgica. Resultados. Se incluyeron 28 pacientes sometidos al procedimiento trans anal y laparoscópico de forma simultánea; al 57 % se les realizó una ileostomía de protección. Hubo complicaciones en el 60,7 % de los pacientes; ocurrieron cuatro casos de fuga anastomótica. No se presentó ninguna mortalidad perioperatoria. Conclusiones. La tasa de morbilidad perioperatoria es acorde con lo reportado en la literatura. Se resalta la importancia de la curva de aprendizaje quirúrgica y de incluir la calificación de la integridad meso-rectal dentro del informe patológico. Se requiere seguimiento a largo plazo para determinar el impacto en desenlaces oncológicos, calidad de vida y morbilidad

Introduction. Surgery is the pillar of curative treatment for rectal cancer. Total meso-rectal excision has improved oncological outcomes, decreasing locoregional recurrence rates and impacting overall survival. The use of this technique in tumors of the middle or distal rectum is a surgical challenge, in which the trans anal route allows overcoming technical difficulties. Method. A retrospective observational study was carried out, collecting information from patients with middle and distal rectal cancer undergoing surgery with this technique, in two level 4 institutions in Medellín, Colombia, between January 2017 and March 2022. Results. Twenty-eight patients were included; their demographic characteristics, perioperative morbidity, and surgical specimen were analyzed. All patients underwent the trans anal and laparoscopic procedures simultaneously; 57% underwent a protective ileostomy. There was no perioperative mortality. Complications occurred in 60.7% of the patients. Only four cases of anastomotic leak occurred. Conclusions. The perioperative morbidity rate is consistent with that reported in the literature; the importance of the surgical curve and to include the qualification of the meso-rectal integrity within the pathological report is highlighted. Long-term follow-up is required to determine the impact on oncological outcomes, quality of life, and morbidity

Effect of preoperative anxiety level on postoperative pain, analgesic consumption in patients undergoing laparoscopic sleeve gastrectomy: an observational cohort study

Abstract Backgraund: This prospective observational cohort study aimed to investigate the relationship between preoperative anxiety levels and postoperative pain and analgesic requirement in patients undergoing laparoscopic sleeve gastrectomy. Methods: Forty two female patients with body mass index ≥ 35, who underwent laparoscopic sleeve gastrectomy for treatment of obesity were included in the study. Spielberger's state and trait anxiety scales were used in this study. Demographic data of the patients, anesthetic and analgesic drugs during the surgery, pain levels measured with verbal analog scale at the postoperative 1st, 4th, 12th, and 24th hour, sedation levels measured with the Ramsay sedation scale, and the amount of analgesic consumed were recorded. Anesthesiologist, surgeon, and patient were not informed of the anxiety level results. The relationship between preoperative anxiety and postoperative pain and analgesic consumption was evaluated by Spearman's correlation analysis. Stepwise multiple linear regression analysis was applied. Normal Distribution control was performed by applying the Shapiro-Wilk test to residual values obtained from the final model. Results: There was no relationship between trait anxiety level and postoperative pain and analgesic consumption. A correlation was found between state anxiety level and pain level up to 24 hours and analgesic consumption (p < 0.05). According to the obtained model it had been observed that the university graduates consumed more analgesic compared to other education level groups. Conclusion: In this study, a relationship was found between preoperative state anxiety level and 24-hour pain scores and analgesic consumption in patients who underwent laparoscopic sleeve gastrectomy under general anesthesia.
