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.

Two-staged surgical management for complicated Boerhaave syndrome with esophagectomy and deferred gastroplasty: A case report.

INTRODUCTION AND IMPORTANCE: Boerhaave syndrome is a rare, challenging entity with high morbimortality rates. Therefore, early diagnosis and prompt treatment are needed. However, a standardized technique has not been developed, especially in large esophageal ruptures. PRESENTATION OF CASE: A female patient of 69 years with an acute thoracic syndrome consistent with severe retrosternal pain of sudden onset, radiating to the left hemithorax, vomiting, and dyspnea that began after food intake associated with subcutaneous emphysema, hypotension, and tachycardia. An A-CT was performed, revealing an esophageal perforation, and Boerhaave syndrome was diagnosed. The patient was taken to esophagectomy and gastroplasty. 2,5 years after the procedure, the patient was without long-term complications, and only dysphagia was present. CLINICAL DISCUSSION: The differential diagnoses of acute thoracic syndromes are needed to be ruled out; however, it usually delays the diagnosis of Boerhaave syndrome. Therefore, early diagnosis (<24 h) may impact this patient's outcomes. On the other hand, esophagectomy can be feasible to control the acute condition and permit a digestive tract reconstruction. CONCLUSION: In patients with large esophageal ruptures and concomitant septic shock, an esophagectomy is an option to control the source of infection and to permit early digestive tract reconstruction.

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.

Perioperative mortality in Colombia: perspectives of the fourth indicator in The Lancet Commission on Global Surgery - Colombian Surgical Outcomes Study (ColSOS) - a protocol for a multicentre prospective cohort study.

INTRODUCTION: Death following surgical procedures is a global health problem, accounting for 4.2 million deaths annually within the first 30 postoperative days. The fourth indicator of The Lancet Commission on Global Surgery is essential as it seeks to standardise postoperative mortality. Consequently, it helps identify the strengths and weaknesses of each country's healthcare system. Accurate information on this indicator is not available in Colombia, limiting the possibility of interventions applied to our population. We aim to describe the in-hospital perioperative mortality of the surgical procedures performed in Colombia. The data obtained will help formulate public policies, improving the quality of the surgical departments. METHODS AND ANALYSIS: An observational, analytical, multicentre prospective cohort study will be conducted throughout Colombia. Patients over 18 years of age who have undergone a surgical procedure, excluding radiological/endoscopic procedures, will be included. A sample size of 1353 patients has been projected to achieve significance in our primary objective; however, convenience sampling will be used, as we aim to include all possible patients. Data collection will be carried out prospectively for 1 week. Follow-up will continue until hospital discharge, death or a maximum of 30 inpatient days. The primary outcome is perioperative mortality. A descriptive analysis of the data will be performed, along with a case mix analysis of mortality by procedure-related, patient-related and hospital-related conditions ETHICS AND DISSEMINATION: The Fundación Cardioinfantil-Instituto de Cardiología Ethics Committee approved this study (No. 41-2021). The results are planned to be disseminated in three scenarios: the submission of an article for publication in a high-impact scientific journal and presentations at the Colombian Surgical Forum and the Congress of the American College of Surgeons. TRIAL REGISTRATION NUMBER: NCT05147623.

Mitral valve repair in severe mitral regurgitation after blunt chest trauma.

Mitral valve insufficiency is a pathological condition frequently caused by etiologies such as rheumatic heart disease, ischemic cardiomyopathy, leaflets prolapse, endocarditis, rupture of a chordae tendineae, ventricular disorders or congenital heart defects among others. Nevertheless, blunt thoracic trauma, although as a rare cause, can produce valve abnormalities. We describe a case of surgical mitral valve repair of a severe insufficiency caused by blunt chest trauma in a high energy road motorbike accident.

Early preoperative progressive pneumoperitoneum for a symptomatic giant abdominal incisional hernia.

INTRODUCTION AND IMPORTANCE: Early preoperative progressive pneumoperitoneum (PPP) is a technique that helps large eventrations with loss of domain to reintroduce protruded organs. However, a standardized technique has not been developed. This technique has been proved in elective patients, but the evidence is scarce in patients with a high risk of incarceration/strangulation. CLINICAL FINDINGS AND INVESTIGATIONS: We present a 61-year-old patient with history of a thoracoabdominal aneurysm repair, developed a massive incisional hernia with loss of domain. At admission, he presented with abdominal pain and inability to reduce the hernia by himself, however it reduced after clinical examination. Aortic syndromes were excluded. INTERVENTIONS AND OUTCOME: After a multidisciplinary meeting, early PPP was initially performed. Later he was taken to surgery and admitted in the ICU to prevent abdominal hypertension. Medical complications resolved within 14 days. The patient did not report long-term complications. RELEVANCE AND IMPACT: PPP is a technique that pursues the prevention of abdominal hypertension syndrome in patients with large hernias with loss of domain electively. For patients with high risk of hernia complications, the evidence is limited regarding the applicability of early PPP. A multidisciplinary team can improve decision making and therefore reduce the risk of long-term complications. We show a case where PPP was performed in an acute painful, reducible hernia with a high risk of incarceration, showing that this approach can be an option for acutely ill patients.

Minimal invasive surgical resection of myxomas: a three case series study / Resección quirúrgica mínimamente invasiva de mixomas: estudio de tres casos

Abstract Introduction and Objective Cardiac tumors are often unrecognized until autopsies are performed or diagnosed from routine studies based on unspecific symptoms. The most common type of tumor is the myxoma, although rare, upon diagnosis an urgent surgical resection is often required. Previously the ideal surgical approach was a standard median sternotomy, however recently newer surgical techniques have been employed with excellent results. We describe a recent surgical approach via the right lateral minithoracotomy as a minimally invasive intervention with three cases that evidence an appropriate and ideal surgical approach. Method and Patients We present three cases of minimally invasive myxoma resection via the right lateral minithoracotomy. Results and discussion In this three-case series study, no complications were reported peri-operatively nor at the 6 and 12-month follow-ups. In comparison with international literature, surgical approaches in Colombia are comparable with successful resection and little or no complications peri-operatively. Conclusions The right lateral minithoracotomy appears to be a safe approach in myxoma resection. We hope to enhance and promote the surgical community in Colombia to opt for alternative less invasive approaches in these type of cases, to ensure excellent results and promote further research as seen in other countries.

Resumen Introducción y Objetivo Los tumores cardíacos no suelen ser diagnosticados hasta la realización de autopsia o en otros casos como hallazgos incidentales. El tumor cardiaco más común es el mixoma, aunque es poco frecuente; en el momento del diagnóstico a menudo se requiere una resección quirúrgica urgente. Anteriormente el enfoque quirúrgico era una atriotomía abierta derecha; sin embargo, recientemente se han empleado técnicas quirúrgicas nuevas con excelentes resultados. Describimos una técnica quirúrgica reciente a través de la minitoracotomía lateral derecha como un método mínimamente invasivo con tres casos que evidencian un método quirúrgico apropiado e ideal. Métodos y pacientes: Se presentan tres casos de resección mínimamente invasiva de mixomas a través de una minitoracotomía lateral derecha. Resultados y discusión: Es estos tres casos no se reportaron complicaciones perioperatorias ni durante el seguimiento a los 6 y 12 meses. En comparación con otras series de casos en la literatura, el enfoque en Colombia ha sido comparable tanto en los resultados exitosos como con las técnicas quirúrgicas, sin complicaciones asociadas. Conclusiones La minitoracotomía lateral derecha puede ser considerada segura en resección de mixoma. Con este tipo de reportes se espera suscitar en la comunidad médica la elección de alternativas quirúrgicas mínimamente invasivas para garantizar excelentes resultados y promover la investigación, como se evidencia en el resto del mundo.

Giant Intrapericardial bronchogenic cyst associated with congestive heart failure and atrial fibrillation: a case report.

BACKGROUND: Large intracardiac bronchogenic cysts are rare mediastinal masses. However, they must always be considered in the differential diagnosis of heart failure with abnormal chest X-ray. CASE PRESENTATION: We present a 60-year-old female patient with de novo atrial fibrillation, heart failure and a very large intrapericardial mass. The patient underwent successful surgical resection, with pathological findings confirming a bronchogenic cyst. CONCLUSIONS: Large bronchogenic cysts located intrapericardially are very rare. However, they should be included in the differential diagnosis of patients presenting with atrial fibrillation and heart failure with abnormal radiologic studies.

Emergency esophagojejunostomy in type IV hiatal hernia: A case report.

Reconstruction of the digestive tract is a surgical challenge; we propose a novel and successful alternative using a large vascularized pedicled jejunum anastomosed to the cervical esophagus in an emergency situation. A 65-year-old female patient in follow-up due to a gigantic type IV paraesophageal hernia, whom underwent surgical hernial defect correction, had friable gastric tissue and esophageal lesions that forced an urgent esophagojejunostomy. Immediate post-operative recovery had no incidents and during the outpatient follow-up no complications were reported. This case report represents a paradigm change in the impossibility of raising the vascularized pedicled jejunum to the neck in an emergency situation.

La reconstrucción del tracto digestivo es un reto quirúrgico. Proponemos una alternativa novedosa y exitosa utilizando un gran yeyuno pediculado vascularizado anastomosado al esófago cervical en situación de emergencia. Una paciente de 65 años en seguimiento por una hernia paraesofágica tipo IV requirió corrección quirúrgica del defecto herniario; tenía tejido gástrico friable y lesiones esofágicas que forzaron una esofagoyeyunostomía urgente. La recuperación posoperatoria inmediata no tuvo incidentes y el seguimiento ambulatorio no mostró complicaciones. Este reporte de caso rompe el paradigma de la imposibilidad de ascender el yeyuno pediculado vascularizado al cuello en una situación de emergencia.

Left diaphragmatic hernia following thoracoabdominal aortic repair: A case report.

INTRODUCTION: Diaphragmatic hernias are somewhat rare complications of thoracoabdominal interventions. Given their late clinical manifestations and misdiagnosis, their incidence is unknown. These hernias have a high mortality risk when an emergency intervention is warranted due to complications from visceral strangulation. CASE PRESENTATION: We present the case of a 67-year-old male with prior history of thoracoabdominal aortic repair, who reconsults due to upper gastrointestinal bleeding. Upon arrival, imaging shows a left diaphragmatic herniation with migration of the stomach, omentum and spleen to the thoracic cavity. Through laparoscopic approach, a left diaphragmatic hernial defect is identified with protrusion of half the stomach, omentum and the posterior aspect of the spleen with a sub capsular tear. Additionally, a severe adhesion syndrome on the chest wall and diaphragm were also evident, with entrapment of the inferior lobe of the left lung. The contents were successfully reduced, however pulmonary decortication and extensive adhesiolysis through thoracoscopy was required for complete extraction, enabling a primary repair without tension. CONCLUSIONS: We present an infrequent pathology without an established incidence, which has relevant clinical and surgical implications at any level of care, in this case requiring interdisciplinary management. The suspicion of diaphragmatic hernia in a patient with past medical history of thoracoabdominal aortic repair with non-specific gastrointestinal symptoms is essential. We emphasize the importance of clinical suspicion of this complication once the surgical precedent has been identified.
