Objetivo:
Comparar resultados operatorios y oncológicos de la nefrectomía parcial realizada mediante abordaje laparoendoscópico a través de puerto único (LESS) reutilizable y laparoscópico multipuerto.
Material y método:
Estudio comparativo prospectivo pareado no aleatorizado de pacientes tratados con nefrectomía parcial mediante abordaje LESS híbrido con trocar auxiliar de 3,5 mm (n = 20) y con laparoscopia multipuerto convencional (n = 26).
Resultados:
La media de seguimiento fue 31 ± 18,6 meses. Un caso LESS (5%) se reconvirtió a laparoscopia. No hubo diferencias significativas entre grupos con respecto a edad, sexo, índice de masa corporal, lateralidad, localización, tamaño tumoral o empleo de doble-J; aunque hubo dominancia de ASA-I (p = 0,09) y de histología benigna (p = 0,05) en el grupo LESS. Tampoco hubo diferencias en tiempo operatorio, tiempo de isquemia, empleo de materiales hemostáticos, sangrado estimado, hemoglobina postoperatoria, transfusión u otras complicaciones. Ningún caso precisó ampliar herida cutánea para extracción de espécimen. Los pacientes LESS tuvieron menor tiempo de drenaje (p = 0,006) y menor estancia hospitalaria (p = 0,003). No hubo diferencias en número...
Objective:
To investigate the surgical and oncological outcomes of hybrid laparoendoscopic single-site (LESS) in partial nephrectomy with reusable components compared with multiport laparoscopy.
Material and method:
Hybrid LESS technique with auxiliary 3.5 mm trocar (n = 20) was compared with conventional multiport laparoscopy (n = 26) by a prospective, paired, nonrandomized, and comparative study in partially nephrectomized patients.
Results:
Follow-up average was 31 ± 18.6 months. In one case, LESS was converted to laparoscopy. No differences were found regarding age, sex, body mass index, laterality, localization, tumor size or use of double J stent. Dominance of Loop-I (P = 0.09) and benign histology (P = 0.05) were observed in the LESS group. Neither there were differences regarding operating time, ischemia time, use of hemostatic materials, estimated blood loss, postoperative hemoglobin levels, transfusion or other complications. In any case, to extend the skin incision for specimen extraction was not necessary. Drainage time (P = 0.006) and hospital stay (P = 0.003) were better in LESS patients. Concerning complications, no significant differences were observed according Clavien-D...
