Complications of lipoabdominoplasty without Scarpa fascia preservation versus classic abdominoplasty : a prospective blind study

Introdução: Abdominoplastia é um dos procedimentos cirúrgicos estéticos mais realizados. Seroma é a complicação local mais comum associada com abdominoplastia, com uma incidência média de 10%. A maior incidência de seroma pósoperatório (PO) ocorre no décimo primeiro dia PO. Ecografia abdominal é o método de escolha para o diagnóstico de seroma após abdominoplastia. Novas técnicas surgiram ao longo dos anos na tentativa de trazer melhores resultados estéticos com menos complicações, como lipoabdominoplastia descrita por Saldanha. Porém, estudos anatômicos recentes questionam a necessidade da manutenção da fáscia de Scarpa descrita na técnica de lipoabdominoplastia, descrevendo que em torno de 90% do sistema linfático abdominal está no plano subdérmico e 10% em um sistema linfático profundo justaaponeurose abdominal. O objetivo é comparar a incidência de seroma na lipoabdominoplastia sem preservação da fáscia de Scarpa com a abdominoplastia clássica. Métodos: Coorte prospectiva, cega na qual serão analisados 40 pacientes consecutivos que realizaram abdominoplastia sem lipoaspiração associada (n = 20) ou lipoabdominoplastia (n = 20) no Hospital de Clínicas de Porto Alegre entre abril de 2016 e maio de 2017. Todos foram submetidos à ecografia de parede abdominal no 10o dia PO. Resultados: A incidência de seroma foi de 5% (n = 1) no grupo de abdominoplastia clássica e de 10% (n = 2) no grupo de lipoabdominoplastia, sem diferença estatística. Conclusão: Estes resultados, neste grupo de pacientes, mostram que não houve diferença estatística entre os dois grupos.Introduction: Abdominoplasty is among the most commonly performed surgical procedures. Seroma is the most common local complication associated with abdominoplasty, with an average incidence of 10%. The highest incidence of postoperative (PO) seroma occurs on the eleventh postoperative day (POD). Abdominal ultrasound is the method of choice for diagnosing seroma after abdominoplasty. New techniques have emerged aiming to improve aesthetic results with fewer complications, such as lipoabdominoplasty described by Saldanha. However, recent anatomical studies have questioned the need for Scarpa fascia preservation recommended in the lipoabdominoplasty technique, describing that around 90% of the abdominal lymphatic system is in the subdermal plane, while the other 10% is in a deep lymphatic system near the abdominal aponeurosis. The objective is to compare the incidence of seroma in lipoabdominoplasty without Scarpa fascia preservation to that in classic abdominoplasty. Methods: Prospective blinded cohort in which 40 consecutive patients who underwent abdominoplasty without associated liposuction (n = 20) or lipoabdominoplasty (n = 20) at the Hospital de Clínicas of Porto Alegre between April 2016 and May 2017 were analyzed. All patients underwent abdominal wall ultrasonography on the tenth POD. Results: The incidence of seroma was 5% (n = 1) in the classic abdominoplasty group and 10% (n = 2) in the lipoabdominoplasty group, with no statistical difference. Conclusion: These results showed no statistically significant intergroup difference in seroma development

Liver transplantation utilizing mixed biologic and synthetic arterial conduits

Arterial conduits are necessary in nearly 5% of all liver transplants and are usually constructed utilizing segments of donor iliac artery. However, available segments of donor iliac artery may not be lengthy enough or may not possess enough quality to enable its inclusion in the conduit. Although there are few reports of arterial conduits constructed solely utilizing prosthetic material, no previous reports of conduits composed of a segment of donor iliac artery and prosthetic material (mixed biologic and synthetic arterial conduits) were found in the medial literature to date. Two cases reporting successful outcomes after creation of mixed biologic and prosthetic arterial conduits are outlined in this report. Reason for creation of conduits was complete intimal dissection of the recipient’s hepatic artery in both cases. In both cases, available segments of donor iliac artery were not lengthy enough to bridge infrarenal aorta to porta hepatis. Both patients have patent conduits and normally functioning liver allografts, respectively, at 4 and 31 months after transplant.Mixed biologic and synthetic arterial conduits constitute a viable technical option and may offer potential advantages over fully prosthetic arterial conduits

Transarterial embolization and percutaneous ethanol injection as an effective bridge therapy before liver transplantation for hepatitis C : related hepatocellular carcinoma

Background. Transarterial chemoembolization alone or in association with radiofrequency ablation is an effective bridging strategy for patients with hepatocellular carcinoma awaiting for a liver transplant.However, cost of this therapymay limit its utilization. This study was designed to evaluate the outcomes of a protocol involving transarterial embolization, percutaneous ethanol injection, or both methods for bridging hepatocellular carcinomas prior to liver transplantation. Methods. Retrospective review of all consecutive adult patients who underwent a first liver transplant as a treatment to hepatitis C-related hepatocellular carcinoma at our institution between 2002 and 2012. Primary endpoint was patient survival. Secondary endpoint was complete tumor necrosis. Results. Forty patients were analyzed, age 58 ± 7 years.There were 23 males (57.5%). Thirty-six (90%) out of the total 40 patients were within Milan criteria. Complete necrosis was achieved in 19 patients (47.5%). One-, 3-, and 5-year patient survival were, respectively, 87.5%, 75%, and 69.4%.Univariate analysis did not reveal any variable to impact on overall patient survival. Conclusions. Transarterial embolization, ethanol injection, or the association of both methods followed by liver transplantation comprises effective treatment strategy for hepatitis C-related hepatocellular carcinoma. This strategy should be adoptedwhenever transarterial chemoembolization and/or radiofrequency ablation are not available options
