Postoperative outcomes using Lichtenstein open hernioplasty versus Nyhus preperitoneal hernioplasty in inguinal hernia: A comparative analysis with 1-year follow-up.

Background and Aim: Inguinal hernia is the most common defect of the abdominal wall in 75% and their treatment consists of surgical repair. The technique of choice is laparoscopic because of its overall benefits. However, when this is not available, open approaches may be a viable option. Currently, the most commonly used open techniques are Lichtenstein and Nyhus. However, there are few medium- or long-term studies that have compared outcomes between these two techniques. Methods: This is a retrospective comparative study that included patients undergoing open inguinal hernia correction with mesh, using Lichtenstein open hernioplasty versus Nyhus preperitoneal hernioplasty, in two tertiary referral centers in Bogota, Colombia, during a period of 2 years. A bivariate analysis was performed to compare groups, according to the complications presented between the two techniques. Results: A total of 193 patients were included, of whom 53.36% were men and 112 (58.03%) were approached with the Nyhus technique versus 81 patients with the Lichtenstein technique. Nonabsorbable suture fixation was performed in 100% of patients. Among the main complications, seroma (5.18%), pain (4.14%), bleeding (2.07%), recurrence (10.88%), and reoperation (0.51%) were observed, of which only recurrence showed a statistically significant difference, which is lower in the Nyhus approach (3.57% vs. 20.67%; p < 0.001). No patients died. Conclusions: Both Nyhus and Lichtenstein hernioplasty techniques were shown to cause a low incidence of postoperative complications, with significantly lower recurrence using the Nyhus technique up to 1 year postoperatively.

Mentoring: what to expect from our surgical mentors in Colombia? A Latin American example.

OBJECTIVE: Identifying the scope of surgical mentoring at Pontificia Universidad Javeriana and compare the perceptions of teachers and students to recognize characteristics and competences of such practice and future needs. METHOD: Two surveys were designed to evaluate the existence and importance of mentoring and inquire about the characteristics, qualities and skills expected on mentors. RESULTS: Both groups agree on the importance of having a mentor. 84.2% of teachers consider themselves mentors, however, only 38.6% of students considered them as such. The most relevant quality of the mentor recognized by students was the willingness and ability to teach, while for teachers it was respect. For the students, the most important competence was the ability to explain and teach about the procedures to be performed, while for teachers it was the ability to provide confidence and security. CONCLUSIONS: There is a paradoxical behavior, most students consider they do not have a mentor while most teachers consider to be such. The need to expand the literature regarding mentoring in Colombia specifically in the surgical field was identified.

OBJETIVO: Identificar el alcance del mentoring quirúrgico en la Facultad de Medicina de la Pontificia Universidad Javeriana y comparar las percepciones de docentes y estudiantes, con el fin de reconocer características y competencias de dicha práctica y necesidades a futuro. MÉTODO: Se diseñaron dos encuestas para evaluar la existencia y la importancia del proceso de mentoring e indagar acerca de las características, las cualidades y las competencias esperadas de los mentores. RESULTADOS: Ambos grupos coinciden en la importancia de contar con un mentor. El 84.2% de los docentes consideran ser mentores, pero solo el 38.6% de los estudiantes los consideraron a ellos como tales. Las cualidad más relevantes del mentor reconocidas por los estudiantes fueron la disposición y la habilidad para enseñar, mientras que para los docentes fue el respeto. Para los estudiantes, la competencia más importante fue la capacidad de explicar y enseñar sobre los procedimientos a realizar, mientras que para los docentes fue la capacidad de brindar confianza y seguridad. CONCLUSIONES: Existe un comportamiento paradójico, pues los estudiantes no consideraron contar con un mentor mientras que los docentes sí estimaron serlo. Se identificó la necesidad de ampliar la literatura respecto al mentoring en Colombia, específicamente en el ámbito quirúrgico.

Predicting mortality in penetrating cardiac trauma in developing countries through a new classification: Validation of the Bogotá classification.

Introduction: Penetrating chest trauma (PCT) represents 10% of worldwide mortality, with developing countries counting as some of the most affected by high mortality rates due to cardiac trauma. Colombia is considered one of the most violent countries due to the high mortality rate associated with war and crime, hence the validation of an own classification for penetrating cardiac injuries (PCI) is mandatory. Methods: Retrospective cross-sectional study which included adult patients with PCIs at a level 4 trauma center in Colombia, between January 2018 and April 2020. We used our own system (Bogotá Classification) and compared it with traditional systems (e.g., Ivatury's, OIS-AAST), by analyzing the mechanism of injury (MOI), the hemodynamic status of the patient at admission, the inpatient management, the individual outcomes, and some demographic variables. Bivariate statistical analysis, spearman correlation, and logistic regression were performed. Results: Four hundred and ninety-nine patients were included. Bivariate analysis demonstrated a significant relationship between mortality and hemodynamic state, MOI, its location and degree of lesion, cardiac/vessel injury, cardiac tamponade, time between injury and medical care, fluid reanimation, as well as the Ivatury's classification and the new classification (p < 0.005). The adequate correlation between Ivatury's and Bogotá classification supports the latter's clinical utility for patients presenting with PCI. Likewise, logistic regression showed a statistically significant association among mortality rates (p < 0.005). Conclusions: The Bogotá classification showed similar performance to the Ivatury's classification, correlating most strongly with mortality. This scale could be replicated in countries with similar social and economic contexts.

Surgical management of duodenal perforation after endoscopic retrograde cholangiopancreatography: case series.

BACKGROUND: Complications after endoscopic retrograde cholangiopancreatography (ERCP) are rare, approximately 0.09% to 1.8% are duodenal perforation. This type of injury requires early diagnosis and proper management since the outcomes can be catastrophic, leading to death in 20% of cases. OBJECTIVE: To show our experience in the management of these injuries in order to establish if there is benefit from minimally invasive management versus conventional management. METHOD: Observational, retrospective and descriptive study comparing patients who required surgical management after post-ERCP duodenal perforation in three centers in Bogotá, Colombia, between January 2013 and December 2018. RESULTS: 13 patients were taken to surgical management after duodenal perforation post ERCP, 7 laparoscopically (53.8%), with an average hospital stay of 10.7 days and mortality of 0% and 6 by open route (46.1%), with an average hospital stay of 33 days and mortality of 50%, with a minimum follow-up of 6 months. CONCLUSIONS: Post ERCP duodenal perforation, despite its low incidence, should be suspected due to its high mortality. Laparoscopic surgery is a good tool to address duodenal perforations after ERCP, because it presents a lower rate of complications and mortality.

ANTECEDENTES: Las complicaciones tras la colangiopancreatografía retrógrada endoscópica (CPRE) que necesitan manejo quirúrgico son limitadas y aproximadamente el 0.09-1.8% corresponden a perforación duodenal. Este tipo de lesiones requieren un diagnóstico temprano y un manejo adecuado, ya que los desenlaces pueden ser catastróficos, con una mortalidad reportada de hasta el 20%. OBJETIVO: Presentar nuestra experiencia en el manejo quirúrgico de estas lesiones. MÉTODO: Estudio observacional, retrospectivo y descriptivo, de pacientes que requirieron manejo quirúrgico por perforación duodenal tras CPRE en tres centros de Bogotá, Colombia, entre enero de 2013 y diciembre de 2018. RESULTADOS: Fueron llevados a manejo quirúrgico 13 pacientes, 7 (53.8%) por vía laparoscópica, con una estancia hospitalaria promedio de 10.7 días y una mortalidad del 0%, y 6 (46.1%) por vía abierta, con una estancia hospitalaria promedio de 33 días y una mortalidad del 50%, con seguimiento mínimo a 6 meses. CONCLUSIONES: La perforación duodenal tras una CPRE, pese a su baja incidencia, se debe sospechar por su alta morbimortalidad. La decisión del abordaje quirúrgico está condicionada por el estado clínico del paciente, y por ende está ligada al pronóstico de este.

Retención de videocápsula endoscópica, una nueva enfermedad médico-quirúrgica: serie de casos.

BACKGROUND: The endoscopic video capsule (EVC), a minimally invasive method of study of the gastrointestinal system indicated in occult gastrointestinal bleeding, has as main complication the retention of endoscopic capsule (CR), currently it is managed with direct extraction using double-balloon enteroscopy; however, when it fails due to its location or associated pathologies, the surgical intervention results in the most successful approach. OBJECTIVE: To evaluate clinical characteristics and management of patients with video capsule endoscopy retention. METHOD: From January 2001 to December 2018, a retrospective search was carried out in three centers, of patients with CR diagnosis, clinical variables and approach were evaluated, in addition to a critical review of the literature. RESULTS: 15 patients with a diagnosis of CR (eight 8 women and seven men), average age 65 (range: 45-77). Seven required surgical management, three endoscopic and five medical management. CONCLUSIONS: The CR is a new pathology of low prevalence, the surgical management resulting from a second therapeutic line when the removal of the VCE has not been possible endoscopically, this pathology requires special attention in the patient's medical history and symptoms for diagnosis and management.

ANTECEDENTES: La videocápsula endoscópica (VCE), método mínimamente invasivo de estudio del sistema gastrointestinal indicado en hemorragia digestiva oculta, tiene como principal complicación la retención de la cápsula endoscópica (RCE). Actualmente se maneja con extracción directa empleando enteroscopia de doble balón; sin embargo, cuando falla por su localización o por patologías asociadas, la intervención quirúrgica resulta el método de mayor éxito. OBJETIVO: Evaluar las características clínicas y el manejo de pacientes con RCE. MÉTODO: De enero de 2001 a diciembre de 2018 se realizó un búsqueda retrospectiva, en tres centros, de pacientes con diagnóstico de RCE. Se evaluaron variables clínicas y de manejo, y además se realizó una revisión crítica de la literatura. RESULTADOS: Se hallaron 15 pacientes con diagnóstico de RCE (ocho mujeres y siete hombres), con una edad promedio de 65 años (rango: 45-77). Siete requirieron manejo quirúrgico, tres manejo endoscópico y cinco manejo médico. CONCLUSIONES: La RCE es una patología nueva de baja prevalencia. El manejo quirúrgico resulta ser una segunda línea terapéutica cuando la extracción de la VCE no ha sido posible endoscópicamente. Para su diagnóstico y manejo, esta patología requiere una especial atención a la historia clínica, los antecedentes y los síntomas de los pacientes.
