ABSTRACT

Introdução: A reconstrução cutânea e de tecidos moles na região ao redor do joelho é frequentemente desafiadora para o cirurgião plástico e tem como objetivo fornecer uma boa função articular do joelho com aparência estética aceitável. O planejamento cirúrgico requer considerar a técnica mais simples que leve ao fechamento da ferida, com mínima morbidade na área doadora. Há poucos relatos do uso do retalho anterolateral (ALT) reverso na literatura, em se tratando de defeitos na fossa poplítea, joelho e porção proximal da perna. O objetivo é descrever uma serie de casos de pacientes submetidos à reconstrução de ferida em fossa poplítea, joelho e terço superior da perna com retalho ALT reverso. Métodos: Quatro pacientes, dos quais 3 eram reconstruções de fossa poplítea e 1 reconstrução de joelho e terço proximal da perna. Todos submetidos à ressecção ampla da ferida/ tumor, dissecção do retalho ALT reverso, e transposição para o defeito. Resultados: Follow-up de 2 a 18 meses, evidenciando-se morbidade mínima para área doadora, com cobertura total do defeito e ótimo resultado funcional do membro afetado, com bom resultado estético. Apenas em um dos casos evidenciou-se sofrimento e necrose parcial (15%) do retalho devido a hematoma e compressão do pedículo, nos demais não foi evidenciado sofrimento dos retalhos, deiscência, seroma ou infecção. Conclusão: O retalho ALT da coxa reverso mostrou-se uma opção viável, apresentando bom resultado funcional e estético para a reconstrução cutânea e de tecidos moles na região de fossa poplítea, joelho e terço superior da perna.


Introduction: Cutaneous and soft tissue reconstruction in the region around the knee is often challenging for the plastic surgeon and aimed at providing good knee joint function with acceptable aesthetic appearance. Surgical planning requires considering the simplest technique that leads to wound closure, with minimal morbidity in the donor area. The literature has reported only few cases of the use of the reverse anterolateral (ALT) flap for defects in the popliteal fossa, knee, and leg proximal portion. The objective is to describe a series of cases of patients who underwent reconstruction with a reverse ALT flap for wounds in the popliteal fossa, knee, and upper third of the leg. Methods: Among four patients, three received popliteal fossa reconstructions and one received knee and leg proximal third reconstructions. All the patients underwent wound/tumor extensive resection, dissection of the reverse ALT flap, and transposition to the defect. Results: During follow-up for 2 to 18 months, minimal morbidity was observed in the donor area, with a total coverage of the defect, optimal functional result of the affected limb, and good aesthetic result. Only one case had a partial necrosis (15%) of the flap due to hematoma and pedicle compression. In the other patients, no evidence of flap failure, dehiscence, seroma, or infection were found. Conclusion: The reverse ALT flap was a viable option, presenting good functional and aesthetic results for cutaneous and soft tissue reconstructions in the popliteal fossa, knee, and upper third of the leg.

ABSTRACT

A técnica da anastomose em Y de Roux pode ser utilizada em cirurgias gástrica, biliar, pancreática, oncológica e bariátrica. Visando diminuir o custo da cirurgia, foi desenvolvida uma técnica para confecção de uma alça exclusa utilizando apenas uma carga de grampeador linear, seccionando a alça e realizando a anastomose jejuno-jejunal látero-lateral ao mesmo tempo. Neste artigo de revisão os autores relatam a experiência da realização da técnica em 4 pacientes selecionados do Hospital Santa Casa de Curitiba. Foram descritos os tempos cirúrgicos da técnica, aplicada à cirurgia de gastrectomia parcial com derivação em Y de Roux e esvaziamento linfonodal retroperitoneal em D2.


The Roux-in-Y anastomosis technique may be used in gastric, biliar, pancreatic, oncologic and bariatric surgery. A technique for making an excluded loop using only a linear stapler load was developed, bisecting the handle and carrying out the latero-lateral jejunum-jejunal anastomosis simultaneously to decrease the surgery cost. In this review article the authors report the experience of performing the technique in 4 selected patients of the Hospital Santa Casa de Curitiba. The surgical steps of the technique have been described, applied to partial gastrectomy surgery with bypass Roux-in-Y and retroperitoneal lymph node dissection in D2.

ABSTRACT

PURPOSE: To analyze the viability of using Gelpoint® (single-port access) to make partial and total nephrectomy in pigs and to describe the technical difficulties found during these surgical procedures. METHODS: Ten pigs (Landrace specie) with 20kg in average were distributed in two groups. Group A: total right nephrectomy and Group B: partial left nephrectomy. The procedures were performed inside the Surgical Technique Room from Pontifícia Universidade Católica do Parana (PUCPR). RESULTS: In Group A, time to single-port insertion varied from one to two minutes and total time of the procedures were 20.4±8.2 minutes. Bleeding was under than 20 mL in 70% of animals. Time of instrument excision was 20.7±12 seconds and time of hilum dissection was 3.9±2.2 minutes. In Group B, after total contralateral nephrectomy two surgical procedures were not concluded due to bleeding. In this group, time of surgery was 6.8±4.2 minutes. With the exception of the second surgery, the highest blood volume loss was 50 mL. The mean excision time was 22.3 ± 22.3 seconds. CONCLUSION: Total and partial nephrectomy through umbilical single-access using GelPoint® was feasible and safe in pigs.
