Abstract Objective: To explore the clinical significance of quantitative CT measurement of abdominal fat distribution in the laparoscopic of total surgery of rectal cancer. Methods: The clinical data of 106 patients with rectal cancer admitted to our hospital from Jan. 2018 to Jan. 2019 were retrospectively analyzed. All patients were given laparoscopic radical resection of rectal cancer and given CT examination before surgery. According to the CT quantitative measurement results, patients with visceral fat area (VFA) > 100 cm2 were defined as VFA-L group (54 cases), and patients with VFA≦100 cm2 were defined as VFA-S group (52 cases). The intraoperative indicators (intraoperative blood loss, incision length, operative time, number of cases of conversion to laparotomy, lymph node dissection quantity) and postoperative indicators (postoperative feeding time, postoperative exhaust time, oxygen inhalation time, postoperative hospital stay, incidence rate of complications) indicators and mesangial integrity were compared between the two groups. Results: There were no significant differences in incision length, postoperative feeding time, postoperative exhaust time and oxygen inhalation time between the two groups (P>0.05), and the intraoperative blood loss in VFA-L group was greater than that in VFA-S group, and the operative time and postoperative hospital stay were longer than those in VFA-S group, and the lymph node dissection quantity was less than that in VFA-S group, and the number of cases of conversion to laparotomy was higher than that in VFA-S group, and the incidence rate of postoperative complications was higher than that in VFA-S group, and the mesangial integrity rate was lower than that in VFA-S group (P<0.05). Conclusions: High VFA in patients will increase the operation difficulty and risk of laparoscopic radical resection of rectal cancer, increase the possibility of postoperative complications and prolong hospital stay. Quantitative CT measurement of abdominal fat distribution can evaluate the operation difficulty and risk and provide a basis for surgical procedures and preoperative preparation.
