AIM： To evaluate the usefulness of three-dimensional computed tomography （3DCT） in laparoscopic surgery for colorectal carcinoma. METHODS： Seventy-two patients with colorectal cancer who underwent curative operation at our hospital were enrolled in this study. They were classified into two groups by operative procedures. Sixteen patients underwent laparoscopic surgery, laparoscopic group （LG）, while 56 patients underwent conventional open surgery, open group （og）. At our institution, contrast-enhanced CT is routinely performed as part of intra-abdominal screening and the 3D images of the major regional vessels are described. We have previously described about the preoperative visualization of the inferior mesenteric artery （IMA） by 3DCT. This time we newly acquired 3D images of the superior mesenteric artery （SMA）/superior mesenteric vein （SMV）, ileocecal artery （ICA）, middle colic artery （MCA）, and inferior mesenteric vein （IMV）. We have compared our two study groups with regard to five items, including clinical anastomotic leakage. We have discussed here the role of 3DCT in laparoscopic surgery for colorectal carcinoma. RESULTS： The mean length of the incision in LG was 4.6254-0.89 cm, which was significantly shorter than that in og （P〈0.001）. The association between ICA and SMV and SMA was described in the right-sided colectomy. The preoperative imaging of IMA and IMV was created in the rectosigmoidectomy. There was no significant difference in anastomotic leakage between the two groups, but no patients in LG experienced anastomotic leakage.CONCLUSION： Most of the patients are satisfied with the shorter incisional length following laparoscopic surgery. Preoperative visualization of the major regional vessels may be helpful for the secure treatment of the anastomosis in laparoscopic surgery for colorectal carcinoma.
