Estudio comparativo de la extracción de la pieza de nefrectomía laparoscópica mediante una incisión de tipo Pfannenstiel

Abstract

ObjectivesThe aim of our study is to demonstrate that the Pfannenstiel incision is a reliable option in terms of postoperative complications compared to other types of incisions usually performed for kidney extraction after laparoscopic nephrectomy. Materials and methodsRetrospective and comparative study of 256 patients who underwent laparoscopic nephrectomy or nephroureterectomy. Patients were divided into two groups: specimen extraction by Pfannenstiel incision (group 1) and specimen extraction by way of other incisions (group 2). Incisional hernia, surgical site infection, pain score, seroma, haematoma/bleeding, wound dehiscence and muscle paralysis were analyzed in each patient. ResultsPatients in Pfannenstiel group presented a rate of wound complications of 11.72% vs 27.34% with other incisions, p = 0.002, it was significantly inferior the rate of wound dehiscence (5.5% vs 12.5%, p = 0.047) and seroma (3.1% vs 7.8%, p = 0.022). Using multivariate logistic regression, Pfannenstiel incision was a significant protective predictor factor for wound complications (OR = 0.34, p = 0.005). ConclusionsThe Pfannenstiel incision allowed the extraction of bigger kidney masses with less incidence of dehiscence, seroma and in general wound complications. The hospital stay was lower in Pfannenstiel extraction group. These results present this incision as a reliable and safe option in the decision of which incision to select.
