    • Value of Endorectal Ultrasonography in Preoperative Staging of Rectal Cancer

      Objective To determine the accuracy of endorectal ultrasonography (ERUS) in preoperative staging of rectal cancer and investigate the limitations and pitfalls of ERUS. Methods Ninety-four patients with rectal cancer were examined preoperatively by ERUS between September 2008 and November 2009 in this hospital. The size, shape, echo pattern, infiltration depth, and extra-rectal invasion of lesions were observed. The results of ERUS staging were compared with histopathology findings of the resected specimens. Results The overall accuracy of ERUS in T staging was 63.8% (60/94). The accuracies of ERUS for pT1, pT2, pT3, and pT4 tumor were 87.2% (82/94), 76.6% (72/94), 76.6% (72/94), and 97.9% (92/94), respectively. The sensitivity, specificity, and accuracy of ERUS for advanced rectal cancer (pT3+pT4) were 70.8% (34/48), 78.3% (36/46), and 74.5% (70/94), respectively. The sensitivity, specificity, and accuracy of ERUS in lymph node metastasis were 75.0% (42/56), 42.1% (16/38), and 61.7% (58/94), respectively. There was no significant difference of accuracy among various tumor locations above anocutaneous line (P=0.495). The accuracy of ERUS for T staging improved with experience, the T staging accuracy improved from 40.0% after assessment of 30 cases to 81.3% after 94 cases were examined (P=0.026). Conclusions The ERUS provides a good accuracy rate for assessment of the depth of tumor invasion and lymph node metastasis of rectal cancer, and has become an important imaging tool for preoperative staging rectal cancer.

      Objective To assess the cl inical significance of transpedicular screw insertion in lower cervical vertebra assisted by multi-spiral CT (MSCT) three dimentional (3D) image reconstruction techniques. Methods Eight cervical vertebra specimens were examined by MSCT, and the messages were sent to SGI02 Workstation; according to the parameter requirements of lower cervical pedicle fixation, by using post-process of volume rendering (VR) the condition was judged and multi-plannar reformation (MPR) was used to do individual analysis; and the ideal path of screw insertion was obtained andthe related parameters were measured. After preoperative plan being finished, referring to these measured parameters, 3.5 mm screws were inserted into C3-7 pedicles of these 8 specimens. After insertion of screws, MSCT scanning and 3D reconstruction were performed again to evaluate the accuracy of lower cervical pedicle screw inserting. From May 2007 to November 2009, 28 patients who received screw insertion in lower cervical spines were given MSCT scanning and 3D reconstruction to evaluate the illness situation, to confirm shortest fixation volumes, and to collect the parameters of aim pedicle screw insertion. Results The time of insertion for each screw was (392 ± 62) seconds. It was found that one pedicle was clausura (1.25%, 1/80) and five pedicle diameters in coronal view were less than 3 mm (6.25%, 5/80), which all were not fit for screw insertion. A total of 74 screws were placed successfully. One-time success rate of screw insertion was 95.95% (71/74). The total accuracy rate was 91.89% (68/74). Six screws penetrated (8.11%). According to the Richter penetrating classification: grade one was 6.76% (5/74) and grade two was 1.35% (1/74). There were significant differences (P lt; 0.05) in penetrated rate between our study and anatomic landmark local ization (47.37%), Miller methods (25.00%), and there was no significant difference (P gt; 0.05) when compared with Abumi method (6.70%), hopper method (7.10%), pipel ine deoppilation method (5.20%) and navigation technique (11.30%). In cl inical 28 cases, 121 screws were inserted; one pedicle was clausura and one was fissure fracture, which all were unfit for insert screw in preoperative plan, the surgery project was adjusted. After operation, 17 patients (76 screws) were given MSCT scanning again. A total of 67 screws (88.16%) were placed successfully. Nine screws (11.84%) penetrated, grade one was 7.89% (6/76) and grade two was 3.95% (3/76). Conclusion It is accurate to apply MSCT 3D reconstruction techniques to measure the ideal screw canal in preoperative individual ized plan. Strictly following individual quantitative data, the safety and accuracy of the surgery can be improved.
