RESUMEN

OBJECTIVE: To demonstrate our surgical technique of robotic partial nephrectomy (RPN) in a patient with a solitary kidney who received neoadjuvant Pazopanib, highlighting the multidisciplinary approach. MATERIALS AND METHODS: In our video, we present the case of 77-year-old male, Caucasian with 6.6cm left renal neoplasm in a solitary kidney. An initial percutaneous biopsy from the mass revealed clear cell RCC ISUP 2. After multidisciplinary tumor board meeting, Pazopanib (800mg once daily) was administered for 8 weeks with repeat imaging at completion of therapy. Post-TKI image study was compared with the pre-TKI CT using the Morphology, Attenuation, Size, and Structure criteria showing a favorable response to the treatment. Thereafter, a RPN was planned3. Perioperative surgical outcomes are presented. RESULTS: Operative time was 224 minutes with a cold ischemia time of 53 minutes. Estimated blood loss was 800ml and the length of hospital stay was 4 days. Pathology demonstrated a specimen of 7.6cm with a tumor size of 6.5cm consistent with clear cell renal carcinoma ISUP 3 with a TNM staging pT1b Nx. Postoperative GFR was maintained at 24 ml / min compared to the preoperative value of 33ml / min. CONCLUSIONS: A multidisciplinary approach is effective for patients in whom nephron preservation is critical, providing na opportunity to select those that may benefi t from TKI therapy. Pazopanib may allow for PN in a highly selective subgroup of patients who would otherwise require radical nephrectomy. Prospective data will be necessary before this strategy can be disseminated into clinical practice. Available at: http://www.intbrazjurol.com.br/video-section/20180240_Garisto_et_al.

RESUMEN

AIM: To report the technique for single-port trans-perineal cystoprostatectomy with intracorporeal ileal conduit urinary diversion and lymph nodes dissection using a purpose-built robotic platform (da Vinci SP1098, Intuitive Surgical, Sunnyvale, CA, USA). MATERIALS AND METHODS: In a male cadaver the SP1098 robotic system was used to perform cystoprostatectomy with intracorporeal ileal conduit urinary diversion and lymph nodes dissection by single-port trans-perineal approach. The surgery was completed through a 2.5-cm perineal incision through which a GelPOINT Mini advanced access platform (Applied Medical, Rancho Santa Margarita, CA, USA) and a dedicated 25-mm multichannel port accommodating a 12 x 10-mm oval articulating robotic camera, three 6-mm double-jointed articulating robotic instruments and a 6-mm accessory laparoscopic instrument were positioned. At the planned level of the stoma for the ileal conduit, a 12-mm port was placed through which the EndoGIA® stapler was used to mature the urinary diversion Results: The total operative time was 185 min. The procedure was successfully completed without the need for additional ports placement. The benefits of the trans-perineal approach, particularly in longer procedures as radical cystectomy with intracorporeal urinary diversion, might include the avoided need of Trendelenburg position, with undoubtful advantages for the patient and the anesthesiologist in terms of respiratory mechanics and hemodynamics. CONCLUSIONS: The feasibility of single-port trans-perineal cystoprostatectomy with intracorporeal ileal conduit urinary diversion and lymph nodes dissection using the SP1098 purpose-built robotic platform is demonstrated. The duplication of the described surgical steps in the clinical model is awaited when the platform will be available on the market.

RESUMEN

Background: Urachal cysts (UCs) are secondary to incomplete obliteration of the embryonic urachal duct and may become symptomatic when infected. Treatment is primarily surgical to excise the infected cyst. Surgical approaches include a lower midline laparotomy or minimally invasive (MI) techniques. Case: We present a case of a young male with an infected UC that was treated with a single-incision laparoscopy surgery. The operative technique is described. Conclusion: This approach is a safe and feasible option for the MI management of UCs.

RESUMEN

The epidemiology of Chagas disease was studied in five rural communities located in the eastern region of the Panama Province. Serological tests for Trypanosoma cruzi infection revealed a prevalence of 5.88% (12/204). Hemocultures coupled with polymerase chain reaction (PCR) analysis showed a Trypanosoma rangeli infection rate of 5.88% (12/204). An overall trypanosome infection index of 11.76% (24/204) was detected in this population. A total of 121 triatomine specimens were collected in domestic and peridomestic habitats. Rhodnius pallescens was confirmed as the predominant species. Molecular analysis showed that 17.8% (13/73) of the examined insects were positive for T. cruzi, 17.8% (13/73) for T. rangeli, and 35.6% (26/73) presented mixed infections. Among 73 R. pallescens evaluated, 16.4% (12/73) contained opossum blood meals. The epidemiological implications of these findings are discussed.

RESUMEN

INTRODUCTION: Chagas disease is the main cause of chronic myocardiopathy in Central America. The mechanisms proposed for this cardiac pathology during the chronic phase remain controversial. Several studies have detected the presence of circulating autoantibodies against beta-adrenergic and cholinergic muscarinic receptors of the myocardium in patients with Chagas disease. These autoantibodies can trigger intracellular signals and modify the cardiac function during the progression of the disease. OBJECTIVES: The serological frequency of these autoantibodies was compared among patients with chronic Chagas disease, patients with other cardiopathies and healthy controls. MATERIALS AND METHODS: The prevalence of autoantibodies against beta-adrenergic and cholinergic muscarinic receptors was determined in four groups of Panamenian patients: 53 chagasic patients, 25 serologically negative patients with cardiac insufficiency, 25 patients with cardiac arrhythmia and 25 healthy individuals. RESULTS: The antibodies against autonomic receptors were more frequently observed in patients with chronic chagasic cardiomyopathy (24.5%) compared to the cardiac insufficiency group (20.0%) and the cardiac arrhythmia group (16.0%). The proportion of autoantibodies was significantly different between the groups with chronic chagasic cardiomyopathy and healthy controls (24.5% versus 0%; p = 0.015). Of the 53 chronically infected chagasic patients, 48 (90%) showed some degree of cardiac dysfunction. CONCLUSIONS: The frequency of autoantibodies against autonomic receptors is significantly increased in patients with chronic Chagas disease and in patients with other cardiopathies.

RESUMEN

Introducción. La enfermedad de Chagas es la principal causa de cardiomiopatía crónica en Centroamérica. Existe controversia sobre los mecanismos causantes de la patología cardiaca observada durante la fase crónica de esta parasitosis. Varios estudios han detectado la presencia de autoanticuerpos circulantes dirigidos contra receptores beta-adrenérgicos y colinérgicos muscarínicos del miocardio en pacientes chagásicos, que pueden desencadenar señales intracelulares y alterar la función cardiaca durante el curso de la enfermedad. Objetivo. Nuestro objetivo principal fue comparar la frecuencia sérica de estos autoanticuerpos en pacientes chagásicos crónicos con la observada en pacientes con otras formas de cardiopatía y en controles sanos. Materiales y métodos. Se determinó la prevalencia de autoanticuerpos contra receptores beta-adrenérgicos y colinérgicos muscarínicos en cuatro grupos de pacientes panamelos: 53 pacientes chagásicos, 25 pacientes seronegativos con insuficiencia cardiaca, 25 pacientes con diferentes tipos de arritmia cardiaca y 25 controles sanos. Resultados. Los autoanticuerpos contra receptores autonómicos fueron más frecuentes en el grupo de pacientes con cardiopatía chagásica crónica (24,5%) comparados con el grupo de insuficiencia cardiaca (20,0%) y con el grupo con arritmias cardiacas (16,0%). Al comparar la proporción de autoanticuerpos entre el grupo de pacientes con cardiopatía chagásica crónica y los controles sanos, se detectaron diferencias muy significativas (24,5% versus 0%; p=0,0015). De los 53 pacientes con infección crónica, 48 (90,6%) presentaron algún grado de alteración cardiaca. Conclusiones. En comparación con el grupo de controles sanos, la frecuencia de los autoanticuerpos contra receptores autonómicos se encuentra significativamente aumentada en pacientes con enfermedad de Chagas crónica y con otras formas de cardiopatía.

RESUMEN

BACKGROUND: Fecaloma is a mass of feces accumulated that is much harder in consistency than a fecal impactation. The aim of this report is to give a brief review of this entity and discuss the treatment options for these cases. CASE PRESENTATION: We present the case of a 12-year-old boy who developed a fecaloma associated with chronic constipation. This is a rare case on a child which was treated by a sigmoid colectomy after failure of conservative measures of evacuation. CONCLUSION: Fecaloma should be considered in the differential diagnosis of patients with history of chronic constipation and abdominal mass.

RESUMEN

OBJECTIVES: Traditionally, chronic empyema has been treated by thoracotomy and decortication. Some recent reports have claimed similar clinical results for videothoracoscopy, but with less morbidity and mortality than open procedures. Our experience with thoracotomy and decortication is reviewed so that the results of this surgical procedure can be adequately evaluated. MATERIALS AND METHODS: From March 1992 to June 2006, 85 patients diagnosed with empyema were treated at Santo Tomás Hospital by the first author. Diagnosis of chronic empyema was based on the duration of signs and symptoms before definitive treatment and imaging findings, such as constriction of the lungs and the thoracic cage. Thirty-three patients fulfilled the criteria for chronic empyema and underwent open thoracotomy and decortication. RESULTS: Twenty-seven patients (81.8 %) were male and the average age of the study group was 34 years. The etiology was pneumonia in 26 patients (78.8%) and trauma in 7 (21.2%). The duration of symptoms and signs before definitive treatment averaged 37 days. All patients had chronic empyema, as confirmed by imaging studies and operative findings. Surgery lasted an average of 139 min. There were 3 (9%) complications with no mortality. The post-operative length of stay averaged 10 days. There were no recurrences of empyema. CONCLUSIONS: Open thoracotomy and decortication can be achieved with low morbidity and mortality. Long-term functional results are especially promising. We suggest that the validation of other surgical approaches should be based on comparative, prospective and controlled studies.
