- Abstract:
- Abstract: Objective To evaluate the application value of the three-dimensional (3D) reconstruction of inferior mesenteric artery
(IMA) via Mimics software in laparoscopic D3 radical resection for rectal cancer. Methods Aretrospective analysis was performed
on the imaging data of 71 patients with rectal cancer who underwent abdominal contrast-enhanced CT examination during June 2016 to January 2018. The 3D reconstruction of IMA which was obtained with Mimics software based on the imaging data was
used to analyze the proportions of 4 different branch types of IMA, and measure the linear distance from IMA root to abdominal
aortic bifurcation and to the left colon artery (LCA). Thirty patients with rectal cancer admitted to hospital from January 2018
to August 2018 were randomly divided into control group (without the 3D reconstruction of IMAbefore surgery) and observation
group (before surgery, the surgical program was established according to the 3D reconstruction of IMA), with 15 patients in each
group. A prospective analysis was performed on the differences in intraoperative and postoperative related indicators, thereby
further evaluating the application of preoperative 3D reconstruction of IMAin laparoscopic D3 radical resection for rectal cancer.
The intraoperative related indicators included operation time, intraoperative blood loss, intraoperative localizations of IMA and
LCA, and the postoperative related indicators included postoperative exhaust time, postoperative drainage tube exudation and
the incidence of anastomotic leakage and intestinal obstruction. Results Among the 4 IMA subtypes, type I and type III were
relatively common, while type IV was rare. The branch type of IMA was related to the linear distance from IMA root to LCA.
In addition, compared with control group, the 3D reconstruction of IMA before surgery significantly shortened operation time
［(152.00±18.16) min vs (135.53±14.06) min, P=0.010］. Meanwhile, preoperative 3D reconstruction of IMA was conductive
to shortening the time for the localizations of IMA and LCA (P=0.004, 0.006), reducing postoperative exhaust time (P=0.029),
decreasing drainage tube exudation (P=0.001). Conclusion The 3D reconstruction of IMA with Mimics software make it easier
for the surgeon to accurately assess the branch types and anatomical localization of IMA and provide important decision-making
information during the radical resection for rectal cancer, which can significantly shorten operation time and improve operation
safety.
