Suturas mecânicas

The authors review the use of staplers in General Surgery, mainly in Gastroenterological Surgery highlighting safety and effectiveness. They emphasize that the mechanic anastomosis are a viable technique and in some conditions, the best way to perform the anastomosis. The use of staplers makes surgery faster and easier and complications are, generally related to surgeon's experience in using them. Although its costs are higher compared to handsewn suture, it can make the patient total cost lower.

Anastomose esôfago-jejunal látero-lateral com grampeador linear cortante complementada por sutura manual

One of the most difficult procedures in digestive-tract surgery is esophago-jejunal anastomosis following total gastrectomy. Cost/benefit analysis of this procedure justifies the use of mechanical staplers, in spite of their high cost. A technical variant of the side-to-side esophago-jejunal anastomosis is presented, which incorporates the use of a cutting linear stapler. Technical maneuvers are easy to perform, the cost of the cutting linear stapler is smaller than the circular ones, the amplitude of the anastomosis is wider and the likelihood of fistulae is smaller when compared to other techniques. The side-to-side esophago-jejunal anastomosis with the cutting linear stapler is always complemented by a manual suture.

Controle dos vasos renais usando clips vasculares e fio cirúrgico em nefrectomias vídeo-assistidas de doadores vivos

OBJETIVO: A nefrectomia laparoscópica em doadores vivos para transplante renal vem assumindo um papel importante na era das cirurgias minimamente invasivas, acarretando menor morbidade aos doadores, e resultados semelhantes à técnica aberta no que se refere ao enxerto renal. O objetivo do presente artigo é relatar a experiência do nosso serviço utilizando a técnica de controle dos vasos renais usando fio cirúrgico e clips vasculares. MÉTODO: Foram realizadas 45 nefrectomias utilizando a técnica vídeo-assistida, com ligadura dos vasos renais com clips de titânio (LT-300) e fio cirúrgico. As variáveis analisadas foram tempo cirúrgico, perda sangüínea, tempo de isquemia quente, permanência hospitalar, necessidade de conversão e complicações. RESULTADOS: O procedimento foi realizado com sucesso em todos os casos. O tempo cirúrgico médio foi de 118 minutos, com perda sangüínea estimada em 84ml e tempo de isquemia quente de 4,3 minutos. Dois casos de íleo prolongado, uma lesão de veia gonadal, um escape de artéria renal e uma necrose de ureter foram observados. A permanência hospitalar média foi de 3,7 dias. O uso de clips vasculares e fio cirúrgico reduziu a perda de tecido venoso comparado à técnica com staplers e gerou redução de custos. CONCLUSÕES: A nefrectomia vídeo-assistida com a técnica descrita é factível e mostrou ser efetiva na contenção de gastos e na redução de tecido venoso perdido.

Hepatectomia direita por videolaparoscopia

The first application of laparoscopic liver surgery consisted of wedge liver biopsies or resection of peripheral lesions, mostly benign. More recently, reports of anatomic left and right hepatectomy have been seen in the literature. Expertise in some centers has evolved to such an extent that even living related donor hepatectomy has been performed. The aim of this paper is to report a laparoscopic right hepatectomy and describe in detail the surgical technique employed. To our knowledge this is the first case performed in Brazil totally laparoscopically. The surgery followed four distinct phases: complete mobilization of the liver; hilum dissection with encircling of right portal vein and right hepatic artery, caval dissection using linear vascular stapler to divide right hepatic vein and parenchymal transection with harmonic shears and firings of linear staplers are used to divide segmental 5 and 8 branches of middle hepatic vein. The liver specimen was removed by Pfannenstiel incision. Intraoperative blood loss was estimated in 120 ml with no need for blood transfusion. Hospital stay was 5 days. Laparoscopic right hepatectomy is feasible, technically demanding but can be safely accomplished by surgeons who have experience in advanced laparoscopic procedures and open hepatic surgery. In Brazil laparoscopic liver surgery is still in its first years and there is a lack of technical description of this complex procedure.
