Introduction) After adopting preoperative assessment of the perigastric vessels using 3D-CT and standardization of the procedures, obesity still influences smooth laparoscopy assisted gastrectomy (LAG). We evaluated the impact of body mass index (BMI) and area of intraperitoneal fat tissue on the risks of LAG.
Patients and methods) The 51 patients who performed LAG for gastric cancer were included. The patients were divided two groups by BMI(25 BMI H group: n=11) and area of intraperitoneal fat tissue (100cm2 AF H group:n=24), respectively. Fat scan, which was computer software operating on abdominal CT, was used to measure the area of intraperitoneal fat tissue. The incidence of postoperative complications, operation time, intraoperative blood loss and number of dissected lymph nodes were compared between each two groups.
Reslults) BMI; The Incidences of postoperative complications of BMI L and H group were 12.5%, 36.4%, respectively (p=0.08). The mean blood loss were 85g and 144g, respectively (p=0.08). There were no significant differences in operation time and the number of dissected LNs. Area of intraperitoneal fat tissue; The incidence postoperative complications (29.2%) and the mean blood loss (139g) of AF H group were significantly higher than those of AF L group (8%, 62g), respectively. The number of dissected LNs of AF H group (25) was significantly lower than that of AF L group (34). There was no significant difference in operation time.
Conclusions) In AF H group, the incidence of postoperative complications and intraoperative blood loss were increased, the dissected number of LNs were decreased. The area of intraperitoneal fat tissue was useful to predict risks of LAG and postoperative complications with higher precision compared with BMI.
