RESUMO
Resumen Introducción: El linfedema es una enfermedad inflamatoria crónica que afecta cerca de 250 millones de personas en el mundo. El tratamiento tradicional es la terapia descongestiva. Últimamente, existe la opción de complementar el tratamiento tradicional con procedimientos quirúrgicos fisiológicos como anastomosis linfáticovenosas y transferencia de linfonodos vascularizados. Sin embargo, la evidencia del uso de la terapia descongestiva en los cuidados pre y posoperatorios en estas cirugías es limitada. Objetivo: Evaluar el uso de terapia descongestiva como complemento a la cirugía de linfedema mediante anastomosis linfáticovenosas y transferencia de linfonodos vascularizados. Materiales y Método: Se realizó una revisión de la literatura en las siguientes bases de datos: Cochrane, Pubmed y Google académico, utilizando los siguientes términos mesh: "anastomosis, surgical", "lymphedema", "perioperative care", "microsurgery", "rehabilitation", "therapy", "lymph nodes", "bypass", "lymphedema and microsurgery". Se incluyó aquellos artículos que describían el uso de la terapia descongestiva en los cuidados pre- y posoperatorios. Resultados: Se identificó un total de 201 artículos y 12 fueron incluidos en el análisis. La evidencia reporta que las terapias más usadas en el cuidado pre- y posoperatorio son compresión, drenaje linfático manual y tratamientos personalizados. Sin embargo, la mayoría de los autores hace una descripción vaga de las terapias mencionadas. Discusión y Conclusión: La evidencia respecto al uso de terapia descongestiva como tratamiento complementario es débil. Los expertos recomiendan su uso, sin embargo, se necesitan futuras investigaciones que describan el uso de cada uno de sus componentes como complemento de procedimientos quirúrgicos fisiológicos para el manejo del linfedema.
Background: Lymphedema is a disease that affects about 250 million people around the world. The traditional treatment is decongestive therapy. In the past years, there is the option to complementing the traditional treatment with physiological surgical procedures such as lymphatic-venous anastomosis (LVA) and vascularized lymph node transfer (VLNT). However, the evidence for the use of decongestive therapy in pre- and post-operative care in these surgeries is limited. Aim: To evaluate the use of decongestive therapy as a complement to lymphedema surgery such a lymphatic-venous anastomosis and transfer of vascularized lymph nodes. Materials and Method: A literature review was carried out in the following databases: Cochrane, Pubmed and Academic Google, using the following mesh terms: "anastomosis, surgical", "lymphedema", "perioperative care", "microsurgery", "rehabilitation", "therapy", "lymph nodes","bypass", "lymphedema and microsurgery". "Those articles that described the use of decongestive therapy in pre- and post-operative care were included. Results: 201 articles were identified and 12 were included in the analysis. The evidence reports that the most used therapies in pre- and post-operative care are compression, manual lymphatic drainage and personalized treatments. However, most of the authors give a vague description of the mentioned therapies. Discussion and Conclusion: The evidence regarding the use of decongestive therapy as a complementary treatment is weak. Experts recommend its use; however, future research is needed to describe the use of each of its components as a complement to physiological surgical procedures for the management of lymphedema.

Resumen Objetivo: Describir resultados de la cirugía de sustitución esofágica con tubo gástrico invertido, vía ascenso retroesternal en dos hospitales pediátricos durante el período marzo 2015 a marzo 2018. Materiales y Método: Un estudio observacional, transversal, con recolección de datos retrospectivo, donde se incluyeron todos los expedientes de pacientes que presentaban patología del esófago por causa adquirida o congénita que fueron operados de sustitución esofágica con tubo gástrico invertido en dos hospitales pediátricos durante 3 años. Resultados: Encontramos 29 niños sometidos a sustitución esofágica, de los cuales 27 cumplieron criterios de inclusión. La edad comprendida entre 2 y 17 años. El 63% corresponde al sexo femenino. La causa más frecuente de sustitución esofágica es por estenosis esofágica por ingesta caustica (92,59%). El 70% presentó algún tipo de complicación luego de la cirugía. La fístula esofagocutánea es la complicación principal con 33,33%. La permanencia en la unidad de cuidados intensivos es menor de 24 horas en un 74% de los niños. Se inicia la vía oral en casi la mitad de casos entre los 10-12 días de posquirúrgico, la estancia hospitalaria es en promedio 18,5 días. La mortalidad es 3,7%. Conclusión: La sustitución esofágica por tubo gástrico invertido vía ascenso retroesternal, es una técnica comparable en resultados a la interposición de colón. Para los autores, el estómago es un órgano ideal para realizar la reconstrucción esofágica, y sus complicaciones son manejables.
Aim: To describe the results of esophageal replacement surgery with an inverted gastric tube via retrosternal ascent in two pediatric hospitals during the period March 2015 to March 2018. Materials and Method: an observational, cross-sectional study with retrospective data collection that included all the records of patients with esophageal discontinuity due to acquired or congenital causes who underwent esophageal replacement surgery with an inverted gastric tube in two pediatric hospitals for 3 years. Results: We found 29 children undergoing esophageal replacement, of which 27 met inclusion criteria. The age between 2 to 17 years. 63% corresponds to the female sex. The most frequent cause of esophageal replacement is esophageal stricture due to caustic ingestion (92.59%). 70% presented some type of complication after surgery. The esophagocutaneous fistula is the main complication with 33.33%. The stay in the intensive care unit is less than 24 hours in 74% of children. The oral route is started in almost half of cases between 10-12 days after surgery; the hospital stay is on average 18.5 days. Mortality is 3.70%. Conclusión: The esophageal substitution by inverted gastric tube via retrosternal ascent is a technique comparable in results to the interposition of the colon. For the authors, the stomach is an ideal organ to perform esophageal reconstruction, and its complications are manageable.

Introduction: There has been conclusive evidence that defunctioning stoma with either transverse colostomy or ileostomy mitigates the serious consequences of anastomotic leakage. However,whether transverse colostomy or ileostomy is preferred for defunctioning a rectal anastomosis remains controversial. The present study was designed to identify the best defunctioning stoma for colorectal anastomosis. Objective: To improve the quality of life in patients with rectal resection and anastomosis and reduce the morbidity before and after closure of the stoma. Patients and Methods The present study included 48 patients with elective colorectal resection who were randomly arranged into 2 equal groups, with 24 patients each. Group I consisted of patients who underwent ileostomy, and group II consisted of patients who underwent colostomy as a defunctioning stoma for a low rectal anastomosis. All surviving patients were readmitted to have their stoma closed and were followed-up for 6 months after closure of their stomas. All data regarding local and general complications of construction and closure of the stoma of the two groups were recorded and blotted against each other to clarify the most safe and tolerable procedure. Results: We found that all nutritional deficiencies, dehydration, electrolytes imbalance, peristomal dermatitis, and frequent change of appliances are statistically more common in the ileostomy group, while stomal retraction and wound infection after closure of the stoma were statistically more common in the colostomy group. There were no statistically significant differences regarding the total hospital stay and mortality between the two groups. Conclusion and Recommendation: Ileostomy has much higher morbidities than colostomy and it also has a potential risk of mortality; therefore, we recommend colostomy as the ideal method for defunctioning a distal colorectal anastomosis.

Abstract Objective: To evaluate the patency of individual and sequential coronary artery bypass in patients with ischemic heart disease. Methods: We searched PubMed, Cochrane Library, Excerpta Medica Database, and ClinicalTrials.gov databases for controlled trials. Endpoints included graft patency, anastomosis patency, occluded rates in left anterior descending (LAD) system and right coronary artery (RCA) system, in-hospital mortality, and follow-up mortality. Pooled risk ratios (RRs) and standardized mean difference (SMD) were used to assess the relative data. Results: Nine cohorts, including 7100 patients and 1440 grafts under individual or sequential coronary artery bypass. There were no significant differences between individual and sequential coronary artery bypass in the graft patency (RR=0.96; 95% CI=0.91-1.02; P=0.16; I2=87%), anastomosis patency (RR=0.95; 95% CI=0.91-1.00; P=0.05; I2=70%), occluded rate in LAD system (RR=1.03; 95% CI=0.92-1.16; P=0.58; I2=37%), occluded rate in RCA system (RR=1.36; 95% CI=0.72-2.57; P=0.35; I2=95%), in-hospital mortality (RR=1.57; 95% CI=0.92-2.69; P=0.10; I2=0%), and follow-up mortality (RR=0.96; 95% CI=0.36-2.53; P=0.93; I2=0%). Conclusion: No significant differences on clinical data were observed regarding anastomosis patency, occluded rate in LAD system, occluded rate in RCA system, in-hospital mortality, and follow-up mortality, indicating that the patency of individual and the patency of sequential coronary artery bypass are similar to each other.

Background: Exclusive coronary revascularization with both mammary arteries could result in lower rates of adverse events in the long term. Aim: To describe the five-year evolution of a cohort of patients operated on with this technique. Material and Methods: Follow up analyzing survival of 73 patients aged 59 ± 9 years (82% men) who underwent exclusive coronary surgery with two mammary arteries between December 1,2010 and April 12,2017. We studied their clinical characteristics, surgical results, operative morbidity and mortality and adverse events up to June 30, 2018. Results: Six patients had two-vessel lesions and 67 three-vessel lesions. The operative risk calculated by additive and logistic EuroSCORE was 2.5 and 2.3%, respectively. A mean of 3.75 anastomoses /patient were performed, 116 with left mammary artery (73 to the anterior descending artery, 38 to a diagonal artery and 5 for other objectives) and 158 with right mammary artery (69 to a first marginal artery, 23 to a second marginal artery and 64 to posterior descending artery). There was one case of mediastinitis and one (1.5%) patient died. The mean follow-up was 64.6 ± 23.7 months. The 5-year survival was 90.4%. Conclusions: Coronary revascularization with two exclusive mammary arteries allowed a complete revascularization of the heart with a low rate of complications and adverse effects at five years.

ABSTRACT Objective: To present our technique of ureteroileal bypass to treat uretero-enteric stric- tures in urinary diversion. Materials and Methods: One hundred and forty-one medical records were reviewed from patients submitted to radical cystectomy to treat muscle-invasive bladder cancer between 2013 and 2015. Twelve (8.5%) patients developed uretero-enteric anastomotic stricture during follow-up. Five patients were treated with endoscopic dilatation and double J placement. Four were treated surgically with standard terminal-lateral im- plantation. Three patients with uretero-enteric anastomotic stricture were treated at our institution by "ureteroileal bypass", one of them was treated with robotic surgery. Results: All patients had the diagnosis of uretero-enteric anastomotic stricture via computerized tomography and DTPA renal scan. Time between cystectomy and diag- nosis of uretero-enteric anastomotic stricture varied from five months to three years. Mean operative time was 120±17.9 minutes (98 to 142 min) and hospital stay was 3.3±0.62 days (3 to 4 days). Mean follow-up was 24±39.5 months (6 to 72 months). During follow-up, all patients were asymptomatic and presented improvement in ure-terohydronephrosis. Serum creatinine of all patients had been stable. Conclusions: Latero-lateral ureter re-implantation is feasible by open or even robotic surgery with positive results, reasonable operation time, and without complications.

Objetivos: La incidencia de lesión uretral bulboprostática secundaria a fractura pelviana es del 5-10%. Una uretroplastia exitosa garantiza el comienzo de la rehabilitación de los pacientes. Presentamos nuestra experiencia en el manejo quirúrgico de la estenosis uretral secundaria a fractura pelviana y resultados funcionales: tasa de éxito, reestenosis, disfunción eréctil e incontinencia urinaria. Evaluamos si existe asociación entre la falta de erecciones postrauma y la reestenosis. Materiales y métodos: Cincuenta y tres pacientes fueron operados durante el período comprendido entre 2001 y 2015. Todos fueron estudiados con cistoscopia flexible, cistouretrografía retrógrada y miccional. La técnica quirúrgica empleada fue la resección y anastomosis primaria. Se utilizó siempre la sistemática del abordaje perineal progresivo para lograr una anastomosis sin tensión. Interrogamos sobre la calidad de las erecciones posterior al trauma y después de la cirugía, y su estado de continencia urinaria. Se realizó un análisis estadístico donde se evaluó si la falta de erecciones era un factor de riesgo para recaída. Resultados: La edad promedio de los pacientes fue de 34,5 (r=17-67) años. La longitud promedio de la estenosis fue de 2,28 cm, siendo la uretra bulbomembranosa la más afectada (89%). La tasa de éxito fue del 86% (46/53), que asciende al 94% (50/53) al asociar un procedimiento endoscópico. Un solo paciente refirió disfunción eréctil postcirugía (1/19; 5,3%). Dos (3,7%) pacientes evolucionaron con incontinencia de orina de esfuerzo. No se hallaron diferencias estadísticamente significativas entre el grupo de pacientes con erecciones y aquellos sin erecciones en cuanto a la posibilidad de reestenosis. Conclusiones: La anastomosis bulbomembranosa por vía perineal es el tratamiento de elección de la estenosis uretral postfractura pelviana. Los índices de incontinencia de orina y disfunción eréctil no aumentan significativamente luego de la uretroplastia. En nuestra experiencia, la falta de erecciones preoperatoria no predice mayor índice de recaídas(AU)
Objectives: Bulboprostatic urethral stricture after pelvic fracture occurs in about 5-10%. A successful urethroplasty guarantees the beginning of patient recovery. We present our experience in the surgical management of posterior urethral stricture after pelvic fracture and functional outcomes (success and failure rates, erectile dysfunction and urinary incontinence). The association between the lack of erections post-trauma and the incidence of restenosis was also evaluated. Materials and methods: 53 patients were operated between 2001- 2015. Preop workout included a flexible cystoscopy and a combination of retrograde and voiding cystourethrogram to define the site and length of urethral stricture. Resection and primary anastomosis was the technique always employed. In all cases the progressive perineal approach was followed in order to achieve a tension free anastomosis. Erectile function and urinary continence were evaluated before and after surgery. Statistical analysis was performed to evaluate if lack of erections was a failure predictor. Results: Median age was 34.5 (r=17-67) years. Median urethral stricture length was 2.28 cm. Bulbomembranous junction was the most affected portion (89%). Success rate was 86% (46/53) ascending to 94% (50/53) when an endoscopic procedure was associated. One patient referred erectile dysfunction after surgery (1/19; 5.3%). Two patients (3.7%) developed stress urinary incontinence. The restenosis rate did not show statiscally differences between the erectile dysfunction and non-erectile dysfunction group. Conclusions: Perineal bulbomembranous anastomosis is the elected procedure for urethral stricture after pelvic fracture. Incidence of urinary incontinence and erectile dysfunction are not significantly elevated after urethroplasty. In our experience, lack of erections before surgery does not predict a higher rate of restenosis(AU)

RESUMO Objetivo: avaliar os fatores associados ao não fechamento de ileostomia protetora após ressecção anterior do reto com excisão total do mesorreto por câncer retal, a morbidade associada ao fechamento destas ileostomias e a taxa de estomia permanente em pacientes com adenocarcinoma retal. Métodos: estudo retrospectivo de 174 pacientes consecutivos com diagnóstico de tumores retais, dos quais 92 foram submetidos à ressecção anterior do reto com intenção curativa, anastomose coloanal ou colorretal e ileostomia de proteção. Foi realizada análise multivariada visando a determinar os fatores associados à permanência definitiva da estomia, assim como o estudo da morbidade nos que se submeteram à reconstrução do trânsito. Resultados: no período de seguimento de 84 meses, 54 dos 92 pacientes avaliados (58,7%) tiveram a ileostomia fechada e 38 (41,3%) permaneceram com a estomia. Entre os 62 pacientes que tiveram a ileostomia fechada, 11 (17,7%) apresentaram algum tipo de complicação pós-operatória: três com deiscência de anastomose ileal, cinco com obstrução intestinal, dois com infecção de ferida operatória e um com pneumonia. Oito destes pacientes necessitaram de um novo estoma. Conclusão: de acordo com a análise multivariada, os fatores associados à permanência da estomia foram fístula de anastomose, presença de metástases e fechamento da ileostomia durante quimioterapia.
ABSTRACT Objective: to evaluate the factors associated with non-closure of protective ileostomy after anterior resection of the rectum with total mesorectum excision for rectal cancer, the morbidity associated with the closure of ileostomies and the rate of permanent ileostomy in patients with rectal adenocarcinoma. Methods: we conducted a retrospective study with 174 consecutive patients diagnosed with rectal tumors, of whom 92 underwent anterior resection of the rectum with coloanal or colorectal anastomosis and protective ileostomy, with curative intent. We carried out a multivariate analysis to determine the factors associated with definite permanence of the stoma, as well as studied the morbidity of patients who underwent bowel continuity restoration. Results: In the 84-month follow-up period, 54 of the 92 patients evaluated (58.7%) had the ileostomy closed and 38 (41.3%) remained with the stoma. Among the 62 patients who had the ileostomy closed, 11 (17.7%) presented some type of postoperative complication: three had ileal anastomosis dehiscence, five had intestinal obstruction, two had surgical wound infection, and one, pneumonia. Eight of these patients required a new stoma. Conclusion: according to the multivariate analysis, the factors associated with stoma permanence were anastomotic fistula, presence of metastases and closure of the ileostomy during chemotherapy.

ABSTRACT Purpose: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. Materials and Methods: We prospectively collected data from consecutive patients that underwent RARP. Patients with at least 6 months of follow-up were included in the analysis for the following outcomes: time to complete VUA, continence and complications related to anastomosis. Nerve-sparing status, age, BMI, EBL, pathological tumor staging, and prostate size were evaluated as possible factors predicting early and midterm continence. Results were compared with current literature. Results: Data from 60 patients was assessed. Mean time to complete VUA was 34 minutes, and console time was 247 minutes. Continence in 6 months was 90%. Incidence of urinary leakage was 3.3%, no patients developed bladder neck contracture or postoperative urinary retention. On multivariate analysis, age and pathological staging was associated to 3-month continence status. Conclusion: Our data show that, during early experience with RARP in a public university hospital, it is possible to achieve good results regarding continence and other outcomes related to VUA. We also found that age and pathological staging was associated to early continence status.

ABSTRACT Background Since Chagas disease has esophageal manifestations with different degrees of involvement, the best surgical option is controversial, especially for patients with advanced chagasic megaesophagus and recurrent symptoms after previous treatment. Objective To assess the early and late outcomes of esophagocardioplasty in a series of patients with advanced recurrent chagasic megaesophagus. Methods This descriptive study included 19 older patients with recurrent megaesophagus grade III/IV and positive immunofluorescence for Chagas disease. They had undergone cardiomyotomy with anterior fundoplication a mean of 16.5 years ago. Serra-Doria esophagocardioplasty was selected to treat the recurrence. The patients were followed to assess postoperative and late complications and the incidence of symptom recurrence. Results In early assessment, five (26.3%) patients presented clinical complications. One (5.2%) patient had a gastrointestinal fistula secondary to esophagogastric anastomotic leak, which responded well to conservative treatment. In the one-year follow-up, 18 (94.7%) patients could swallow normally and had no vomiting. Three years after surgery, 10 (62.5%) of 16 patients could swallow normally, and 3 (19.3%) patients complained of vomiting. Five years after surgery, only 5 (38.4%) of 13 patients could swallow normally and 7 (53.8%) had vomiting. Conclusion Serra-Doria esophagocardioplasty for the treatment of advanced recurrent megaesophagus had mild postoperative complications and good success rate in the short-term follow-up. In the long-term follow-up, it proved to be a poor surgery choice because of the high incidence of symptom recurrence, compromising quality of life. This procedure should be indicated only for patients with advanced recurrent megaesophagus without clinical conditions to undergo esophageal resection.
RESUMO Contexto A doença de Chagas, por apresentar manifestações esofágicas com diferentes graus de acometimento, faz com que haja controvérsias quanto a melhor opção cirúrgica; principalmente para pacientes com megaesôfago chagásico avançado e com recidiva de sintomas após tratamento prévio. Objetivo Avaliar o resultado precoce e tardio da esofagocardioplastia em uma série de pacientes com megaesôfago chagásico avançado e recidivado. Métodos Estudo descritivo, com 19 pacientes idosos com megaesôfago Grau III/IV recidivado e com imunoflorescência positiva para doença de Chagas. A cirurgia prévia foi a cardiomiotomia com fundoplicatura anterior, com tempo médio de realização de 16,5 anos. A cirurgia de eleição para o tratamento da recidiva foi a esofagocardioplastia de Serra-Dória. Realizou-se avaliação precoce para estudar as complicações pós-operatórias e tardias, para avaliar a incidência de recidiva de sintomas. Resultados Na avaliação precoce, 5 (26,3%) pacientes apresentaram complicações clínicas. Um (5,2%) paciente apresentou fístula digestiva consequente a deiscência da anastomose esofagogástrica, mas com boa evolução com o tratamento conservador. Na avaliação de 1 ano de pós-operatório, 18 (94,7%) pacientes apresentavam deglutição normal e sem regurgitação. Com 3 anos de pós-operatório, de 16 pacientes analisados; 10 (62,5%) pacientes apresentavam deglutição normal e 3 (19,3%) se queixavam de regurgitação. Com 5 anos de pós-operatório, de 13 pacientes analisados; somente 5 (38,4%) apresentavam deglutição normal e 7 (53.8%) com regurgitação. Conclusão A esofagocardioplastia de Serra-Dória, no tratamento cirúrgico do megaesôfago avançado recidivado, apresentou complicações pós-operatórias de baixa morbidade e com boa resolutividade, na avaliação precoce. Na avaliação de longo prazo, demonstrou não ser um procedimento cirúrgico adequado, pela alta incidência de recidiva de sintomas, com comprometimento da qualidade de vida. Deve ser indicada somente em pacientes com doença avançada recidivada, sem condições clínicas de serem submetidas à ressecção esofágica.

OBJECTIVES: This study aimed to evaluate the safety and efficacy of a new nickel-titanium shape memory alloy compression anastomosis ring, NiTi CAR 27, in constructing an anastomosis for colorectal cancer resection compared with conventional staples. METHODS: In total, 234 consecutive patients diagnosed with colorectal cancer receiving sigmoidectomy and anterior resection for end-to-end anastomosis from May 2010 to June 2012 were retrospectively analyzed. The postoperative clinical parameters, postoperative complications and 3-year overall survival in 77 patients using a NiTi CAR 27 compression ring (CAR group) and 157 patients with conventional circular staplers (STA group) were compared. RESULTS: There were no statistically significant differences between the patients in the two groups in terms of general demographics and tumor features. A clinically apparent anastomotic leak occurred in 2 patients (2.6%) in the CAR group and in 5 patients (3.2%) in the STA group (p=0.804). These eight patients received a temporary diverting ileostomy. One patient (1.3%) in the CAR group was diagnosed with anastomotic stricture through an electronic colonoscopy after 3 months postoperatively. The incidence of postoperative intestinal obstruction was comparable between the two groups (p=0.192). With a median follow-up duration of 39.6 months, the 3-year overall survival rate was 83.1% in the CAR group and 89.0% in the STA group (p=0.152). CONCLUSIONS: NiTi CAR 27 is safe and effective for colorectal end-to-end anastomosis. Its use is equivalent to that of the conventional circular staplers. This study suggests that NiTi CAR 27 may be a beneficial alternative in colorectal anastomosis in Chinese colorectal cancer patients.

La cirugía de revascularización mio-cárdica (CRM) exclusiva con arterias mamarias internas en Y (BIMA-Y) podría ofrecer los mejores injertos en términos de durabilidad y menores tasas de eventos adversos en el largo plazo. Objetivo: Analizar los resultados a corto plazo de esta técnica quirúrgica en un hospital universitario chileno. Métodos: Estudio prospectivo de los pacientes intervenidos de CRM con técnica de BIMA-Y entre diciembre 2010 a mayo 2014. Se incluyeron 67 pacientes, 59 hombres, con edad media 58,6±8,5 años. Cinco (5) tenían enfermedad de dos vasos y 62 de 3 vasos. El EuroSCORE aditivo fue 2.3 y el logístico 2,18%. Todas las cirugías se realizaron por esternotomía media con circulación extracorpórea. Ambas arterias mamarias internas se disecaron usando técnica esqueletizada. La arteria mamaria interna derecha (RIMA) se seccionó y anastomosó con la arteria mamaria interna izquierda (LIMA). La pared anterior se revascularizó con LIMA y las paredes lateral e inferior con RIMA. El seguimiento se extendió hasta Junio del 2015. Resultados: Se efectuaron 3,8 anastomosis/paciente: 109 LIMA (67 a arteria descendente anterior, 37 a una arteria diagonal y 5 para otros objetivos) y 145 RIMA (64 a una primera arteria marginal, 23 a una segunda marginal y 58 a descendente posterior). La revascularización fue completa en todos los casos Hubo 1 infarto perioperatorio, 6 fibrilaciones auriculares, 1 neumonía, 1 dehiscencia esternal y 5 infecciones superficiales. No hubo mortalidad operatoria ni reoperaciones por sangrado. El seguimiento medio fue 39,3±12,1 meses. Cuatro pacientes fallecieron y hubo 2 reintervenciones. Conclusiones: La técnica BIMA-Y permitió una revascularización completa con una baja tasa de complicaciones y efectos adversos en el corto plazo.
Myocardial revascularization with both mammary arteries in "Y" (Y-BIMA) might lead to longer graft duration and better clinical results. Aim: To analyze short term results of Y-BIMA in a series of patients operated on at a Chilean university hospital. Methods: Patients operated on using Y-BI-MA between December 2010 and May 2014 were analyzed. There were 67 patients (59 males) aged 58.6± 2.3 years old. Five patients had 2 vessel di-sease and 62 patients 3 vessel disease. The additi-ve Euroscore was 2.3 % and the logistic score was 2.18%. All operations were performed through a medial sternotomy using extracorporeal circulation. Both mammary arteries were dissected and skeleto-nized. The RIMA was divided and anastomosed to the LIMA. The anterior myocardial was revascularized through the LIMA while the lateral and inferior walls were revascularized through the RIMA. Results: An average 3.8 anastomosis per patient were performed: 67 LIMA to the LAD, 37 to the diagonal artery, and 5 to other targets (total 109 LIMA); RIMA was used in 145 arteries: 64 to a first marginal, 23 to a second marginal and 58 to a posterior descending artery. Revascularization was complete in all cases. One patient had a postoperative myocardial infarction, 6 developed atrial fibrillation, 1 a pneumonia, 1 a sternal dehiscence and 5 had superficial infections. There was no surgical mortality nor reoperations for bleeding. Patients were followed an average of 39.2±12.1 months. Four patients died and 2 were reoperated on during follow up.

Complete arterial revascularization for the right coronary artery is underused mainly due to technical issues. Herein we report on a new approach for complete arterial revascularization of arterial revascularization for the right coronary artery branches. Complete arterial revascularization for the right coronary artery revascularization was performed in 8 patients using a reverse T composite arterial graft. None of the patients suffered perioperative myocardial infarction. All patients underwent noninvasive coronary imaging, displaying an early patency rate of 100%. Complete arterial arterial revascularization for the right coronary artery revascularization using a reverse T graft offers a new paradigm with enhanced technical flexibility in performing all arterial myocardial complete revascularizations in selected patients.
Revascularização arterial completa para a artéria coronária direita é subutilizada, principalmente devido a problemas técnicos. Nós relatamos uma nova abordagem para a revascularização arterial completa para os ramos da artéria coronária direita. Revascularização arterial completa da artéria coronária direita foi realizada em 8 pacientes usando um enxerto T arterial composto inverso. Nenhum dos pacientes sofreu infarto do miocárdio perioperatório. Todos os pacientes foram submetidos a exame de imagem não invasivo coronária não invasiva, exibindo taxa de patência precoce de 100%. Revascularização arterial completa da artéria coronária direita com enxerto inversa T oferece um novo paradigma com maior flexibilidade técnica na execução todas as revascularizações arteriais completas do miocárdio em pacientes selecionados.

INTRODUCTION: The descending branch of the lateral femoral circumflex artery is an option for coronary artery bypass grafting. OBJECTIVE: To evaluate the early patency and adaptation of lumen diameter using multidetector computed angiotomography. METHODS: Thirty-two patients were selected to undergo coronary artery bypass grafting using the descending branch of the lateral circumflex artery, the internal thoracic artery, and other grafts. Evaluations were carried out through high resolution computed tomography performed on the 7th and 90th postoperative day. Diameters of the descending branch of the lateral circumflex artery and the left internal thoracic artery were measured 3 cm before the distal anastomosis, in the middle portion, and 3 cm after the proximal anastomosis. Diameters were compared using paired t-test (P<0.05). RESULTS: Descending branch of the lateral femoral circumflex artery wDescending branch of the lateral femoral circumflex artery was used in 26 patients, as its use was not viable in six patients (18%). It was used as composite graft in all cases. The anterior descending branch was revascularized by the left internal thoracic artery in all cases. Patency rates of the descending branch of the lateral femoral circumflex artery were 96% and 92%, respectively. No occlusions were observed in the left internal thoracic artery (LITA) and no ischemic events were observed in the descending branch of the lateral circumflex. Descending branch of the lateral femoral circumflex artery increased the lumen diameter in the middle (P=0.001) and distal portions (P=0.006); the left internal thoracic artery (LITA) increased in the middle portion (P=0.001). CONCLUSION: Similar to the left internal thoracic artery, the descending branch of the lateral femoral circumflex artery showed high patency rate and positive luminal adaptation. This early evaluation confirms the descending branch of the lateral femoral circumflex artery as a potential alternative for grafting. Due to anatomical variations, preoperative femoral angiographic evaluation appears to be mandatory.
INTRODUÇÃO: O ramo descendente da artéria circunflexa lateral é um enxerto pouco avaliado e pode ser uma opção para a revascularização do miocárdio. OBJETIVO: Avaliar a perviabilidade e o remodelamento arterial do ramo descendente da artéria circunflexa lateral, em três meses de seguimento, por meio de angiotomografia de artérias coronárias. MÉTODOS: Foram analisados 32 pacientes submetidos à revascularização do miocárdio com ramo descendente da artéria circunflexa lateral, artéria torácica interna esquerda e outros enxertos. A avaliação foi realizada por meio da tomografia computadorizada de alta resolução, realizada no 7º e 90º dias de pós-operatório. O diâmetro do ramo descendente da artéria circunflexa lateral foi medido 3 cm antes da anastomose distal, na porção média e 3 cm após a anastomose proximal. As mesmas medidas foram realizadas para a artéria torácica interna esquerda. Os diâmetros foram comparados pelo método t de Student pareado (significância P<0,05). RESULTADOS: O ramo descendente da artéria circunflexa lateral foi adequado para a utilização em 26 pacientes. Em seis (18%) pacientes, o ramo descendente da artéria circunflexa lateral era inviável. Em todos os casos, o ramo descendente da artéria circunflexa lateral foi empregado sob a forma de enxerto composto. Todos os pacientes receberam artéria torácica interna esquerda para o ramo descendente anterior. A perviabilidade do ramo descendente da artéria circunflexa lateral foi de 96% e 92%, em 7 e 90 dias de pós-operatório, respectivamente. Não foram detectadas oclusões da artéria torácica interna esquerda. Não foram detectados sinais de espasmo do ramo descendente da artéria circunflexa lateral. O ramo descendente da artéria circunflexa lateral apresentou aumento de diâmetro nas porções média (P=0,001) e distal (P=0,006) e a artéria torácica interna esquerda, aumento na porção média (P=0,001). CONCLUSÃO: O remodelamento positivo sugere que o ramo descendente da artéria circunflexa lateral tem comportamento semelhante à artéria torácica interna esquerda e pode ser uma excelente opção para a revascularização do miocárdio com enxertos arteriais. Em virtude das variações anatômicas, estudos de pré-operatório podem auxiliar na seleção de casos.

Background: The use of mechanical anastomoses reduce the length of gastrointestinal surgical procedures. Aim: To report the experience with mechanical functional terminal anastomoses in bowel surgery. Material and Methods: Prospective non randomized registry of all mechanical anastomoses carried out in a surgical service. Results: A total of 327 patients (193 women) were analyzed. Two hundred and one anastomoses were ileo-colonic and 126 were entero-enteral. Seventeen percent of patients experienced some complication. Fourteen required a new operation due to peritonitis or deep infection of the surgical site. The global rate of anastomotic dehiscence was 3.1 percent. No differences in the rate of complications between surgeons with experience and trainees were observed. Conclusions: Mechanical anastomoses in bowel surgery are safe and require a short learning period to be used.
Se presenta nuestra experiencia con la anastomosis terminal funcional con sutura mecánica en cirugía intestinal. La serie corresponde a 327 pacientes, un 59 por ciento de género femenino. Del total de anastomosis 201 fueron íleo colónicas y 126 entero enterales. El instrumento de sutura más utilizado fue de 75 u 80 mm de longitud y no se registran incidentes durante la confección de la anastomosis. La morbilidad específica se encuentra en el 17 por ciento de la serie, sin diferencias entre los dos tipos de anastomosis. Catorce paciente fueron reoperados por peritonitis o infección profunda del sitio quirúrgico La tasa global de dehiscencia anastomó-tica fue de un 3,1 por ciento ( 5 y 4 casos respectivamente) sin alcanzar significación estadística. Al comparar si la anastomosis fue realizada por un cirujano con experiencia o en formación, tampoco se encontraron diferencias estadísticamente significativas, por lo que nos parece una técnica segura y con una corta curva de aprendizaje.

PURPOSE: Issues related to body image and a permanent stoma after abdominoperineal resection may decrease quality of life in rectal cancer patients. However, specific problems associated with a low anastomosis may similarly affect quality of life for patients undergoing low anterior resection. The aim of this study was to compare quality of life of low rectal cancer patients after undergoing abdominoperineal resection versus low anterior resection. METHODS: Demographics, tumor and treatment characteristics, and prospectively collected preoperative quality-of-life data for patients undergoing low anterior resection or abdominoperineal resection for low rectal cancer between 1995 and 2009 were compared. Quality of life collected at specific time intervals was compared for the two groups, adjusting for age, body mass index, use of chemoradiation, and 30 days postoperative complications. The short-form-36 questionnaire was used to determine quality of life. RESULTS: The query returned 153 patients (abdominoperineal resection = 68, low anterior resection = 85) with a median follow-up of 24 (3-64) mo. The after abdominoperineal resection group had a higher mean age (63 + 12 vs. 54 + 12, p < 0.001) and more American Society of Anesthesiologists classification 3/4 patients (65 percent vs. 43 percent, p = 0.03) than low anterior resection. Other demographics, tumor stage, use of chemoradiation, overall postoperative complication rates, and quality-of-life follow-up time were not statistically different in both groups. Patients undergoing abdominoperineal resection had a lower baseline short-form-36 mental component score than those undergoing low anterior resection. However, 6 mo after surgery this difference was no longer statistically significant and essentially disappeared at 36 mo after surgery. CONCLUSION: Patients undergoing abdominoperineal resection for low rectal cancer have a similar long-term quality of life as those undergoing low anterior resection. These findings can help clinicians to better counsel patients with low rectal cancer who are being considered for abdominoperineal resection.

Context: Controversy regarding the best operative choice for familial adenomatous polyposis lays between the morbidity of restorative proctocolectomy and the supposed mortality due to rectal cancer after ileorectal anastomosis. OBJECTIVES: To evaluate operative complications and oncological outcome after ileorectal anastomosis and restorative proctocolectomy. Methods: Charts from patients treated between 1977 and 2006 were retrospectively analyzed. Clinical and endoscopic data, results of treatment, pathological reports and information regarding early and late outcome were recorded. Results: Eighty-eight patients - 41 men (46.6 percent) and 47 women (53.4 percent) - were assisted. At diagnosis, 53 patients (60.2 percent) already had associated colorectal cancer. Operative complications occurred in 25 patients (29.0 percent), being 17 (19.7 percent) early and 8 (9.3 percent) late complications. There were more complications after restorative proctocolectomy (48.1 percent) compared to proctocolectomy with ileostomy (26.6 percent) and ileorectal anastomosis (19.0 percent) (P = 0,03). There was no operative mortality. During the follow-up of 36 ileorectal anastomosis, cancer developed in the rectal cuff in six patients (16,6 percent). Cumulative cancer risk after ileorectal anastomosis was 17.2 percent at 5 years, 24.1 percent at 10 years and 43.1 percent at 15 years of follow-up. Age-dependent cumulative risk started at 30 years (4.3 percent), went to 9.6 percent at 40 years, 20.9 percent at 40 years and 52 percent at 60 years. Among the 26 patients followed after restorative proctocolectomy, it was found cancer in the ileal pouch in 1 (3.8 percent). Conclusions: 1. Operative complications occurred in about one third of the patients, being more frequently after the confection of ileal reservoir; 2. greater age and previous colonic carcinoma were associated with the development of rectal cancer after ileorectal anastomosis; 3. patients treated...
Contexto: As controvérsias quanto a melhor forma de tratamento da polipose adenomatosa familiar confrontam a morbidade da proctocolectomia restauradora contra a suposta mortalidade decorrente de câncer retal após íleo-reto anastomose. OBJETIVOS: Avaliar as complicações operatórias e a evolução oncológica dos pacientes submetidos a íleo-reto anastomose ou proctocolectomia restauradora. Métodos: Analisaram-se os dados dos doentes tratados entre 1977 e 2006, procedendo ao levantamento de dados clínicos gerais, endoscópicos, resultados do tratamento cirúrgico, dados anatomopatológicos e informações sobre a evolução precoce e tardia dos pacientes. Resultados: Foram tratados 88 pacientes, sendo 41 homens (46,6 por cento) e 47 mulheres (53,4 por cento). Por ocasião do diagnóstico, 53 pacientes (60,2 por cento) já tinham câncer colorretal associado à polipose. Registraram-se complicações operatórias em 25 doentes (29,0 por cento) dentre os 86 operados, sendo 17 (19,7 por cento) precoces e 8 (9,3 por cento) tardias. Houve mais complicações após proctocolectomia restauradora (48,1 por cento) em comparação às proctocolectomias com ileostomia (26,6 por cento) e íleo-reto anastomose (19,0 por cento) (P = 0,03). Não houve mortalidade operatória. O risco cumulativo de câncer retal após íleo-reto anastomose foi de 17,2 por cento após 5 anos, 24,1 por cento após 10 anos e 43,1 por cento após 15 anos de seguimento pós-operatório. Já o risco cumulativo idade-dependente começou a existir a partir de 30 anos (4,3 por cento), passando para 9,6 por cento aos 40 anos, 20,9 por cento aos 40 anos e 52 por cento aos 60 anos. Entre os pacientes submetidos a bolsa ileal com seguimento (26), apenas 1 doente (3,8 por cento) desenvolveu câncer na bolsa ileal. Conclusões: 1. Ocorreram complicações operatórias em cerca de 1/3 dos pacientes, sendo mais frequentes após a confecção de bolsa ileal; 2. idade maior, tempo de seguimento e câncer colônico prévio se associaram...

OBJECTIVE: To prospectively evaluate the outcome of using a two-suture technique for the vesicourethral anastomosis (VUA) during radical retropubic prostatectomy (RRP). MATERIAL AND METHODS: Two groups of 50 patients each underwent nerve-sparing RRP for localized prostate cancer by one surgeon. In one group, the vesicourethral anastomosis was performed using 2 Vicryl 2-0 stitches placed at the 3- and 9-o'clock positions and in the other group 6 Vicryl 2-0 stitches were placed at the 2-, 4-, 6-, 8-, 10- and 12-o'clock positions. The intraoperative and perioperative parameters analyzed were time to perform the VUA, time to remove the drain and hospitalization. The rate of incontinence, anastomotic stricture and erectile function were included in the outcome analysis. RESULTS: The anastomotic time differed statistically between the 2 groups (mean 3.3 minutes for the 2-suture group and 10.5 minutes for the 6-suture group, p < 0.0001) with similar periods of drain removal (mean 3.12 days for the 2-suture group and 3.45 days for the 6-suture group; p = 0.13) and hospitalization (mean 4.66 days for the 2-suture group and 5.3 days for the 6-suture group; p = 0.09). The functional outcome was excellent for the 2-suture group with no patient suffering from incontinence or anastomotic strictures 1 year postoperatively, while in the 6-suture group there were 2 patients (4 percent) suffering from incontinence (2 underwent sling procedure) and 1 patient suffered from anastomotic stricture. CONCLUSION: The low number of sutures in the 2-suture VUA technique reduces operating times, does not influence perioperative and intraoperative parameters and results in excellent functional outcome.

Background: Total colectomy with ileorectal anastomosis (IRA) is an alternative to the ileoanal pouch for the surgical treatment of ulcerative colitis in a selected group of patients. This technique leaves rectal mucosa Hable to develop persistent proctitis, dysplasia and cancer Aim: To describe short and long-term results of IRA and to assess the presence of dysplasia. Material and methods: Descriptive study of patients treated with IRA. The data were obtained from the clinical records, and the present status was evaluated with an interview. A proctoscopy and biopsy was offered free of cost to the contacted patients. Results: Between 1978 and 2005, 26 patients were operated. One patient presented an anastomotic leakage that was treated with a loop ileostomy There was no operative mortality. Twenty-three patients were followed for a períod of 1 to 23 years. Three patients evolved as Crohn 's disease and two of them needed a proctectomy. Three patients died of non-related diseases. In the remaining 17, the average evacuation rate was 3.7/24 h and all were continent. None developed a rectal cancer Only two patients had their planned annual endoscopic surveillance. In 2 of the 11 patients who accepted endoscopy and biopsy, a low-grade dysplasia was found. Conclusions: IRA has low morbidity and acceptable functional results in this selected group of patients. No patient present high-grade dysplasia or cancer; however, the adherence to the endoscopic follow-up ispoor.
