Intravenous antibiotic therapy after laparoscopic appendectomy in acute complicated appendicitis: the patient clinical response is the key.

INTRODUCTION: The guidelines about acute complicated appendicitis (ACA) recommend 3-5 days of postoperative intravenous antibiotics (IVA). Nevertheless, the time selected by the surgeon can vary according to patient clinical response, ACA type, and professional experience. Once an adequate clinical response is obtained, the change from IVA to oral antibiotic (OA) could be realized without the waiting time established with satisfactory results. OBJECTIVE: Determine if a short course of IVA and/or switch to oral route is safe based on the patient clinical response. MATERIALS AND METHODS: Observational prospective cohort study from a general surgery reference center database since July 2019. RESULTS AND CONCLUSION: 48 patients with ACA intraoperative findings were included. Regarding postoperative antibiotic management, only preoperative IVA: 7 (14.58%), IVA 1-3 days: 1 (20.83%), IVA 1-3 days and change to OA: 21 (43.75%), IVA > 3 days: 6 (12.5%), and only OA: 3 (27.08%). The bivariate analysis did not show statistically significant differences in reconsultation (p = 0.81), rehospitalization (p = 0.44), and surgical site infection (p = 0.56) between the antibiotic scheme based on the postoperative clinical response and the traditional one regarding intra-abdominal collection rate, the hospital stays, and hospitalization costs.

INTRODUCTION: Las guías sobre apendicitis aguda complicada (ACA) recomiendan 3-5 días de antibióticos intravenosos (IVA) postoperatorios. No obstante, el tiempo seleccionado por el cirujano puede variar según la respuesta clínica del paciente, tipo de ACA y experiencia profesional. Una vez obtenida una adecuada respuesta clínica, el cambio de IVA a antibiótico oral (OA) podría realizarse sin esperar el tiempo establecido con resultados satisfactorios. OBJETIVO: Determinar si un ciclo corto de IVA y/o el cambio a OA según la respuesta clínica del paciente es seguro. MATERIALES Y MÉTODOS: Estudio observacional de cohorte prospectivo a partir de la base de datos de un centro de referencia en cirugía general desde julio del 2019. RESULTADOS Y CONCLUSIÓN: Se incluyeron 48 pacientes con hallazgos intraoperatorios de ACA. En cuanto al manejo antibiótico postoperatorio, solo IVA preoperatorio: 7 (14.58%), IVA 1-3 días: 1 (20.83%), IVA 1-3 días y cambio OA: 21 (43.75%), IVA > 3 días: 6 (12.5%) y solo OA: 3 (27.08%). El análisis bivariado no mostró diferencias estadísticamente significativas en la reconsulta (p = 0.81), la rehospitalización (p = 0.44) y la infección del sitio operatorio (p = 0.56) entre el esquema de antibióticos basado en la respuesta clínica postoperatoria y el tradicional con respecto a tasa de colección intrabdominal, estancia hospitalaria y costos de hospitalización.

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.

Long-Term Outcomes of Laparoscopic Common Bile Duct Exploration Through Diathermy, Choledochotomy, and Primary Closure: A 6-Year Retrospective Cohort Study.

Background and Objective: Choledocholithiasis is a frequent pathology, unfortunately when its endoscopic management fails, there is no consensus of how it should be addressed. The aim of this study was to evaluate the safety, feasibility, and long-term outcomes of laparoscopic common bile duct exploration (LCBDE) using electrosurgery (coagulation) for choledochotomy followed by primary closure after endoscopic treatment failure. Materials and Methods: A retrospective cohort study of patients who underwent LCBDE from 2013 to 2018 was conducted in Bogotá, Colombia. Clinical demographics, operative outcomes, recurrence rate of common bile duct stones, and long-term bile duct complications were analyzed. A descriptive analysis was performed. Results: A total of 168 patients were analyzed. Most of the patients were males (53.37%) with a median age of 73 years with no comorbidities (65%). Stone clearance was successful in 167 patients (99.4%). Nonlethal complications were noted in 3 patients during the surgery or in the immediate postoperative (1.79%) and managed with T-tube or endoscopically. No cases of mortality surgery related were observed. There were no signs of any type of biliary injury or stricture observed in any of the patients during the 24-month follow-up period. Conclusions: LCBDE with diathermy and primary closure is a safe and effective treatment option for choledocholithiasis for failed endoscopic retrograde cholangiopancreatography in terms of long-term outcome as well as short-term outcome.

Minimally invasive management of Mirizzi syndrome Va: Case series and narrative review of the literature.

INTRODUCTION: Mirizzi's Syndrome (MS) is a rare pathology, known to be a challenge for the surgeon. In the surgical management, open approach vs laparoscopic is a topic of discussion due to anatomic variations. The aim of this study is to analyze our experience in the laparoscopic management of this condition in Type Va. METHODS: We made a descriptive retrospective study of patients diagnosed with MS type Va and treated by laparoscopic approach from 2014 to 2019, in two high volume centers of Bogotá, Colombia. RESULTS: 1073 patients who presented complications from gallstones were evaluated, of which 16 were diagnosed with MS type Va. 75% were females and 25% males; 80% presented jaundice and 90% abdominal pain; 12 patients showed cholecystoduodenal fistula and 4 cholecystocolic fistula. All patients underwent laparoscopic management, total cholecystectomy and fistula resection with primary closure was possible on a 100% of the patients. Conversion rate was 0%. The follow up was 18 months. CONCLUSION: Laparoscopic management of MS is feasible and safe; the experience of the surgery group and selection of the patients is the key to a successful outcome.

Divertículos duodenales periampulares y el fallo técnico-terapéutico durante colangiopancreatografía retrógrada endoscópica (CPRE) / Periampullary duodenal diverticula and technical-therapeutic failure during endoscopic retrograde cholangiopancreatography (ERCP)

Resumen Introducción y objetivos: los divertículos duodenales periampulares (DDP) son infrecuentes y su hallazgo es incidental. Además, se clasifican en tres tipos según Boix por la cercanía a la ampolla mayor. El objetivo de este estudio fue realizar una descripción de nuestra experiencia con esta anomalía anatómica y demostrar la forma en que esto afecta la tasa de éxito técnica y terapéutica del procedimiento. Material y métodos: se realizó un estudio de corte transversal, con recolección de datos de forma retrospectiva en un período de 5 años de pacientes con divertículos periampulares duodenales. Se evaluó el fracaso terapéutico, complicaciones y dificultad de canulación de la vía biliar. Resultados: se evaluó un total de 214 pacientes, con una relación mujer-hombre de 2,15:1. La distribución de los sujetos por tipo de DDP fue: tipo 1 (29,9 %), tipo 2 (51,9 %) y tipo 3 (18,2 %). La indicación más frecuente de CPRE fue los cálculos del conducto biliar común en un 53,3 %. El DDP tipo 1 presentó mayor dificultad de canulación (11,6 %) y falla terapéutica (28,12 %). Conclusión: la presencia de DDP durante la CPRE se asocia con una mayor falla técnica (falla en la canulación) y falla terapéutica (persistencia de la obstrucción biliar). Además, estas fallas aumentan considerablemente cuando se trata de una papila intradiverticular tipo 1 de la clasificación según Boix. Por lo anterior, se sugiere que los procedimientos endoscópicos biliares en estas condiciones sean realizados por endoscopistas con gran experiencia con el fin de minimizar la probabilidad de falla técnica y terapéutica, y las complicaciones asociadas.

Abstract Introduction and objectives: Periampullary duodenal diverticula are infrequent, and their finding is incidental. They are classified into three types according to Boix due to their proximity to the larger blister. This study aims to describe the experience with this anatomical abnormality and to demonstrate how this affects the technical and therapeutic success rate of the procedure. Materials y Methods: A cross-sectional study was conducted, with retrospective data collection over a 5-year period of patients with periampullary duodenal diverticula. Therapeutic failure, complications, and difficulty of cannulation of the bile duct were evaluated. Results: A total of 214 patients were evaluated, with a female-male ratio of 2.15: 1. The distribution of the subjects by type of PDD was: type 1 (29.9%), type 2 (51.9%), and type 3 (18.2%). The most frequent indication for ERCP was common bile duct stones in 53.3%. Type 1 PDD presented greater difficulty in cannulation (11.6%) and therapeutic failure (28.12%). Conclusion: The presence of PDD during ERCP is associated with greater technical failure (failure in cannulation) and therapeutic failure (persistence of biliary obstruction). In addition, this failures increases considerably when it is a type 1 intradiverticular papilla of the Boix classification. Therefore, it is suggested that biliary endoscopic procedures in these conditions are performed by highly experienced endoscopists to minimize the probability of technical and therapeutic failure and associated complications.

Evaluación de factores asociados a formación de colecciones intraabdominales en apendicectomía monopuerto para apendicitis aguda complicada.

OBJETIVO: Comparar los desenlaces entre la apendicectomía por laparoscopia por puerto único y multipuerto, y establecer si existe diferencia en el riesgo de colección intraabdominal posoperatoria. MÉTODO: Se realizó un estudio retrospectivo, observacional, mediante 116 historias clínicas de pacientes llevados a apendicectomía laparoscópica por único puerto y multipuerto en dos centros médicos. RESULTADOS: Desarrollaron colección intraabdominal 12 (10.3%) pacientes. No se encontraron diferencias entre ambas técnicas en cuanto al desarrollo de colección intraabdominal (p = 0.242), no hubo diferencia entre ambas técnicas en cuanto a sangrado intraoperatorio (p = 0.012) y el tiempo quirúrgico fue mayor en el grupo de puerto único (17.4 minutos en promedio). El 62.5% de los pacientes con sangrado > 50 ml desarrollaron colección intraabdominal. CONCLUSIONES: No se evidenció superioridad de ninguna de las dos intervenciones en apendicitis complicada, pero sí se confirma que la apendicectomía laparoscópica por puerto único es un procedimiento seguro, factible, no inferior y con tasas similares de complicaciones en comparación con la técnica convencional de apendicectomía laparoscópica. OBJECTIVE: To compare the decreases between the appendectomy by single port vs. multiport laparoscopy and to establish if there is a difference in the risk of postoperative intra-abdominal collection. METHOD: Retrospective study was carried out using 116 medical records of patients undergoing laparoscopic appendectomy through a single port and multiport in two medical centers. RESULTS: 12 (10.3%) patients developed an abdominal collection. No differences were found between the two techniques in terms of intra-abdominal collection development (p = 0.242), there was no difference between the two techniques in terms of intraoperative bleeding (p = 0.012), the surgical time was greater in the single-port group (17.4 min on average). 62.5% of patients with bleeding > 50 mL developed intra-abdominal collection. CONCLUSIONS: There was no evidence of superiority of either of the two interventions in complicated appendicitis, but it does confirm that single-port laparoscopic appendectomy is a safe, feasible, noninferior procedure and with similar complication rates compared to the conventional laparoscopic appendectomy technique.

Úlcera marginal perforada tras bypass gástrico. ¿Cuál es el manejo ideal? A propósito de un caso.

En la última década, las úlceras marginales en pacientes tras un bypass gástrico se han convertido en un problema mucho más frecuente, y hoy en día aún no está clara su etiología. Se han descrito numerosos factores de riesgo, tales como un alto consumo de tabaco o de antiinflamatorios no esteroideos (AINE), entre otros. Presentamos el caso de una paciente con úlcera gástrica perforada en el remanente gástrico, con antecedente de bypass gástrico hace 4 años, tabaquismo y uso de AINE, por lo que se lleva a manejo laparoscópico con parche de Graham, adecuada evolución clínica y resolución de la sintomatología.In the last decade, marginal ulcers in post-gastric bypass patients have become a much more frequent problem. Multiple risk factors have been described, such as high consumption of tobacco or high consumption of nonsteroidal anti-inflammatory drugs (NSAIDs), among others. We present a case report of a patient with perforated gastric ulcer in the gastric pouch, with a history of gastric bypass 4 years ago associated with smoking and NSAIDs, so it is taken to laparoscopic management with Graham's patch management, adequate clinical evolution and resolution of symptoms.

Emergency laparoscopic resection of the anterior rectum due to rectal trauma secondary to compressed air, case report.

In the XIX century, the surgeon faces surgical challenges due to the creation of new technologies. Accidental or compressed air-induced injury to the colon and rectum is rare. We present the case of a 45-year-old patient who consults the emergency department, then a high-pressure rectal pneumatic trauma, with clinical findings of peritonism, managed with a Hartmann-type colostomy. and anterior resection of the rectum using laparoscopy, with findings of rectosigmoid perforation. With this, it can be demonstrated that minimally invasive surgery is a feasible approach in hemodynamically unstable patients without contraindication for pneumoperitoneum.

Biliogastrointestinal reconstruction with duodenectomy and pancreas preservation by laparoscopy after open failed coledocoduodenostomy.

Las lesiones de la vía biliar y las reconstrucciones biliodigestivas son un reto quirúrgico para el cirujano, además de una situación que exige su máxima habilidad y conocimiento. Presentamos el caso de un paciente con una reconstrucción biliodigestiva por una lesión de vía biliar abierta la cual fue fallida. Se decide llevar a reconstrucción biliodigestiva por laparoscopia, con preservación del páncreas, en un asa con hepatoyeyunostomía y gastroyeyunostomía. Este caso ilustra la posibilidad del manejo con cirugía mínimamente invasiva incluso en los casos más graves; sin embargo, se requiere alta experticia al momento de abordarlo.Bile duct injury and bile duct reconstruction are a surgical challenge for the surgeon, in addition to a situation that demands maximum skill and knowledge. We present a case of a patient with a biliodigestive reconstruction due to an open bile duct injury which was failed, it was decided to take a biliodigestive reconstruction by laparoscopy, with preservation of the pancreas, with hepaticoyejunostomy and gastroyejunostomy. This case illustrates the possibility of handling with minimally invasive surgery even in the most severe cases, however, they require high expertise when addressing it.

Uso de mallas de polipropileno en el reparo de la hernia inguinal con herida sucia o contaminada / Use of polypropylene meshes in the repair of inguinal hernia with dirty or contaminated wound

Introducción. La hernioplastia con malla de polipropileno es la técnica de elección para el reparo de las hernias inguinales. Actualmente, existe controversia sobre esta técnica en pacientes con heridas sucias o contaminadas; sin embargo, la evidencia en la literatura médica ha demostrado que su uso puede ser seguro. Los autores presentan su experiencia con las mallas de polipropileno en la cirugía contaminada para cierre de hernias inguinales.Método. Se realizó un estudio observacional retrospectivo en el que se incluyeron los pacientes mayores de 18 años atendidos entre enero de 2017 y diciembre de 2018 por presentar hernias inguinales, que requirieron tratamiento quirúrgico de urgencias, y que presentaban heridas sucias o contaminadas. Los criterios evaluados fueron: infección de la herida quirúrgica, morbilidad y mortalidad, necesidad de remoción de la malla y recurrencia de la hernia.Resultados. Diez pacientes fueron sometidos a cirugía de urgencias, requiriendo resección intestinal por necrosis: nueve de ellos, por hernias estranguladas y, uno, por apendicitis perforada. En uno de los diez pacientes, se consideró sucia la herida por presentar necrosis intestinal y perforación. Los nueve restantes presentaban necrosis intestinal sin perforación, por lo cual se consideraron heridas contaminadas. La infección de la herida ocurrió en 1/10 pacientes con infección del sitio operatorio superficial; la eliminación de la malla no fue necesaria en ningún paciente durante todo el período de estudio. No se observaron recidivas y no hubo mortalidad.Conclusión. El uso de malla de polipropileno para la corrección de hernias inguinales, en pacientes con heridas sucias o contaminadas, es efectivo y seguro, con una morbilidad aceptable y buenos resultados a corto plazo

Introduction: Polypropylene mesh hernioplasty is the technique of choice for the repair of inguinal hernias. Currently, there is controversy about this technique in patients with dirty or contaminated wounds. However, evidence in the medical literature has shown its use can be safe. The authors present their experience in the use of polypropylene meshes in contaminated surgery to close inguinal hernias.Methods: A retrospective observational study was conducted in patients older than 18 year-old between January 2017 and December 2018. Were included those with inguinal hernias, requiring emergency surgical treatment, and presented contaminated or dirty wounds. The inclusion criteria were infection of the surgical wound, the need for removal of the mesh removal and recurrence of the hernia.Results: Ten patients underwent emergency surgery, requiring bowel resection for necrosis: nine of them for strangulated hernias and, one for perforated appendicitis. In one of the ten patients, the wound was considered dirty due to intestinal necrosis and perforation. The remaining nine had intestinal necrosis without perforation, so they were considered contaminated wounds. Wound infection occurred in 1/10 patients (10%) with superficial operative site infection; mesh removal was not necessary in any patient during the entire study period. No recurrence was observed and there was no mortality.Conclusion: The use of polypropylene mesh for the correction of inguinal hernias in patients with contaminated and dirty wounds is effective and safe, with acceptable morbidity and good short-term results
