ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the preoperative diagnosis value of 64-slice spiral CT three dimensional angiography (3D CTA) for the vascular invasion in gastric cancer.</p><p><b>METHODS</b>CT images of 40 patients diagnosed as gastric cancer by endoscope,who proceeded to surgical exploration from August 2006 to December 2007,were collected. These images were rebuilt by 3D CTA to judge vascular invasion by gastric cancer in comparison with the surgical finding as standard reference.</p><p><b>RESULTS</b>Successful 3D CTA reconstructions were performed for all these 40 patient images. Out of 40 cases, 14 cases presented vascular invasion in the 3D CTA, and 12 of 14 cases were proved to have vascular invasion in the surgery. For assessing vascular invasion with CTA, the sensitivity was 98.1% and the specificity was 96.4% respectively (Chi Square chi(2)=0.0099,P>0.05). There was no significant differences regarding vascular invasion in gastric cancer between preoperative 3D CTA assessment and surgical finding.</p><p><b>CONCLUSION</b>Sixty-four-slice spiral CT 3D angiography is effective in assessing vascular invasion in gastric cancer and is also valuable in clinical application.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the impact on sexual function, local recurrence and survival after total mesorectal excision (TME) with autonomic nerve preservation (PANP) of rectal cancer.</p><p><b>METHODS</b>One hundred and five patients after TME with PANP were followed by means of questionnaire on postoperative genital function [TME + PANP(+) group], and the results of 110 patients after TME without PANP [TME + PANP(-) group] were compared with, also their local recurrence and 5-year survival were retrospectively analyzed.</p><p><b>RESULTS</b>TME + PANP(+) group was compared to TME + PANP(-) group: the erection dysfunction, 33.3% vs 63.2%; the ejaculation dysfunction, 43.8% vs 70.0% (P < 0.01), there were significant differences between two groups, but no difference in local recurrent rate and 5-year survival rate (7.6% vs 5.5%; 63.4% vs 59.7%, P > 0.05).</p><p><b>CONCLUSION</b>The TME with PANP of rectal surgery ensure the radical cure of rectal cancer, at the same time reasonably save the postoperative sexual function and obtain satisfactory postoperative survival.</p>
