Stomach Cancer

Reduced port robotic distal gastrectomy

Gastric cancer is one of the most common malignancy worldwide. Surgical resection of the tumor is the only curative treatment for gastric cancer. However, surgical procedure accompanies postoperative pain and prolonged hospitalization. To lessen the surgical trauma and stress, minimally invasive surgery were introduced. Laparoscopic gastrectomy was accepted as safe and effective alternative to open gastrectomy. Furthermore, reduced port and single port laparoscopic gastrectomy are considered to minimize the surgical trauma during gastrectomy. However, limitations of laparoscopic approach using reduced port includes unergonomic posture of surgeon, physiologic tremor and collision of instruments. To overcome these limitations, robot surgery using novel single-site technology enabled surgeons to perform the surgical procedure reducing the number of trocar from three to one for insertion of scope and two robotic arms. Previously, successful application of single-site technology for cholecystectomy and hysterectomy were reported. The aim of this study is to validate the safety and feasibility of reduced port robotic distal gastrectomy using single-site technology for the surgical treatment of gastric cancer.

First, apply 10 cmH2O positive endexpiratory pressure (PEEP) and measure the increase in central venous pressure (CVP) as well as other preload indexes (central venous pressure, mean arterial pressure, stroke volume variation).

Second, measure the increase in cardiac index after administration of volulyte 300 ml.

If cardiac index increase more than 10%, fluid responsiveness is confirmed.

In urologic robotic surgery with steep Trendelenburg position, maintenance of cardiac preload and cardiac output is important for clinical prognosis. Previous studies reported the positive end-expiratory pressure (PEEP)-induced increase in central venous pressure (CVP) could be a accurate predictor of fluid responsiveness in cardiac surgical patients. The authors attempt to evaluate the predictability of PEEP-induced increase in CVP as well as stroke volume variation in urologic robotic surgery with Steep Trendelenburg position.

In urologic robotic surgery with steep Trendelenburg position, maintenance of cardiac preload and cardiac output is important for clinical prognosis. As a preload index, the predictability of central venous pressure, pulse pressure variation and stroke volume variations may be impaired due to the impaired hemodynamics that result from the effect of increased abdominal pressure and decreased venous return. Previous studies reported the positive end-expiratory pressure (PEEP)-induced increase in central venous pressure (CVP) could be a accurate predictor of fluid responsiveness in cardiac surgical patients. Therefore, the authors attempt to evaluate the predictability of PEEP-induced increase in CVP as well as stroke volume variation in urologic robotic surgery with Steep Trendelenburg position.
