ABSTRACT
Since the first report of robotic surgical system in gastric cancer by Hashizume in 2002, the new generation of minimally invasive technology represented by robotic surgical system has developed rapidly in gastric cancer. The new generation of minimally invasive technology is cha-racterized by faster recovery of patients, better of clinical outcomes and long-term efficacy. In the past 20 years, robotic surgical system has made great progress in clinical application, which is expected to solve the disadvantages and problems of laparoscopic surgery. Experienced surgeon teams have accumulated lots of research experiences in clinical application of robotic surgical system. Robotic surgical system can provide a technologically superior surgical environment for minimally invasive surgery, which could be an effective and feasible alternative to conventional radical gastrectomy. The author investigates the hot issues of robotic radical gastrectomy including the feasibility, safety, short- and long-term outcome and current research status.
ABSTRACT
Introducción: Las lesiones quirúrgicas de las vías biliares (LQVB) se definen como la detención del flujo biliar por ligadura, clipado o estenosis cicatricial, sección parcial o completa de la vía biliar principal o de los conductos biliares aberrantes. Objetivo: Describir la experiencia en el manejo de la lesión quirúrgica de la vía biliar en el Servicio de Cirugía del Hospital Nacional de Itauguá. Pacientes y método: Estudio retrospectivo, descriptivo, observacional de corte transverso,fueron incluidos los pacientes con lesión quirúrgica de la vía biliar atendidos en el Servicio de Cirugía General del Hospital Nacional de Itauguá entre marzo del 2010 hasta noviembre del 2015. Resultados: De los 29 casos de lesión de vía biliar, 25 casos fueron del sexo femenino y 4 del sexo masculino. El promedio de edad fue de 43 años, con una mínima de 17 y una máxima de 74 años. 21 de las lesiones fueron remitidos de otros centros hospitalarios. 14 casos durante cirugías programadas, 21 vía convencional y 8 vía laparoscópica. El diagnóstico intraoperatorio fue en 10 casos. En 14 casos las lesiones fueron complejas (mayor a 50% de la luz o asociada a lesión vascular) donde la reparación en estos pacientes fue la derivación Hepático yeyuno anastomosis en Y de Roux tipo Hepp-Couinaud. La mortalidad fue en 1 caso (3,4%)...
Introduction: Surgical lesions of the bile ducts (LQVB) are defined as the arrest of bile flow by ligation, clipping or scar stenosis, partial or complete bile duct or bile ducts abhorrent section. Objective: To describe the experience in the management of the surgical lesion of the bile in the surgery service of the National Hospital of Itauguá. Patients and methods: study retrospective, descriptive, observational transverse cut, they were included patients with surgical bile duct injury treated in General Surgery from the National Hospital of Itauguá service between March 2010 until November 2015. Results: Of the 29 cases of injury biliary tract, 25 cases were female and 4 male. The average age was 43 years, with a minimum of 17 and maximum of 74 years. 21 lesions were referred from other hospitals. 14 cases during elective surgery, 21 conventional route and 8 laparoscopically. The intraoperative diagnosis was in 10 cases. In 14 cases the lesions were complex (greater than 50% of the light or associated with vascular injury) where repair in these patients was the jejunum Hepático bypass anastomosis Roux-Y Hepp-Couinaud type. Mortality was 1 case (3.4%)...

Objective To explore the correlation of tumor growth and endothelial progenitor cells (EPC) entering blood induced by surgical injury in tumor bearing nude mice. Methods Forty-two tumor bearing nude mice were randomly divided into seven groups (n=6): non-surgical injury groups (1 d and 30 d), anesthetic group, surgical injury groups (24 h, 48 h, 72 h and 30 d after surgery). Blood samples and xenograft tumor tissues were taken from anesthetic group 24 h after anaesthesia and surgical injury groups 24 h, 48 h, 72 h and 30 d after surgery. EPC levels in peripheral blood were measured by flow cytometry, serum VEGF levels were determined by ELISA, microvessel density (MVD) and expression of VEGF were detected by immunohistochemistry. Results The levels of EPC in 24 h post-surgery group, 48 h post-surgery group and 72 h post-surgery group were significantly higher than that in non-surgical injury 1 d group (P<0.05). The levels of VEGF in 24 h post-surgery group, 48 h post-surgery group, 72 h post-surgery group and anesthetic group were significantly higher than that in non-surgical injury 1 d group (P<0.05). There was no significant difference in MVD among groups (P>0.05). Pearson correlation analysis revealed that serum VEGF levels were related to EPC levels in peripheral blood (r=0.695 6, P<0.01), while EPC levels in peripheral blood were not related to MVD (r=0.221 4, P>0.05), and serum VEGF levels had no correlation with MVD (r=0.224 9, P>0.05). Conclusion Surgical injury has no obvious influence on xenograft tumor growth.
