Diagnostic value and clinical significance of MSCT in postoperative intestinal obstruction of rectal cancer patients / 中华普通外科杂志

ABSTRACT

Objective To evaluate the value of multi-slice spiral computed tomography (MSCT) in diagnosing postoperative intestinal obstruction of rectal cancer.Methods The CT imaging results and clinical manifestation of 50 patients with postoperative intestinal obstruction of rectal cancer confirmed by pathology were reviewed retrospectively.These cases including Miles (24 cases),Dixon (18 cases),Hartmann(8 cases) procedure were collected from Tianjin People's Hospital from 2011 to 2013.Conservative management was done in 10 cases and the remaining 40 patient underwent surgical intervention.Statistical difference between the three kinds of surgical causes of intestinal obstruction was analysed by x2 test.Results Most common cause after Miles and Hartmann postoperative intestinal obstruction was of adhesion,while anastomotic stenosis was the most common reason of intestinal obstruction after Dixon procedure.The difference of incidence of intestinal obstruction caused by hernia and anastomotic stenosis between the three kinds of operation method was statistically significant (x2 =5.382、20.486,P ＜ 0.05).Conclusions MSCT could identify the etiology and site of postoperative intestinal obstruction of rectal cancer,providing favorable imaging evidence for clinical treatment.
