Objective To investigate the influence of preoperative assessment by transrectal ultrasound (TRUS) on the development of operative procedures for rectal cancer. Methods A total of 110 patients with pathologically proven rectal cancer and distance between tumor to dentate line ≤10 cm were enrolled and randomized into group A (n=55) and group B (n=55) according to a computer-generated random sequence. Both TRUS staging and Clinical Staging System (CS staging) were performed preoperatively in group A, while only CS staging was conducted in group B. Preoperative TRUS stage, CS stage, and proposed operative procedures were recorded to compare with the postoperative pathological stage and practical operative procedures. Results A total of 99 patients were assessed. They were randomized into group A (n=49) and B (n=50), and there were no significant differences in baseline characteristics between the two groups. The difference in staging accuracy was statistically significant (P=0.000) between group A (91.8%) and group B (48.0%). Statistically significant improvement (P=0.013) in the accuracy of proposing operative procedures for rectal cancer was observed in group A (93.9%) compared with group B (76.0%). Conclusion TRUS is evidently superior to CS staging in preoperative assessment for rectal cancer, and may remarkably enhance the accuracy of proposing operative procedures. Therefore, TRUS is valuable in preoperative assessment which may help to guide the selection of operative procedures for rectal cancer surgery.
Objective To determine the influence of combinative assessment of 64 multi-slice spiral computer tomography (MSCT) and serum amyloid A protein (SAA ) on the selection of operative procedures in lower rectal cancer.MethodsProspectively enrolled 130 patients diagnosed definitely as lower rectal cancer (distance of tumor to the dentate line ≤7 cm) at West China Hospital of Sichuan University from July 2007 to September 2008 were randomly assigned into two groups with 65 participants, respectively. In one group named MSCT+SAAgroup, both 64 MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT group, only the preoperative MSCT was made. Furthermore, the preoperative staging and predicted operation procedures were compared with postoperative pathologic staging and practical operation program, respectively.ResultsAccording to the criteria, 119 patients with colorectal cancer were actually included into MSCT+SAA group (n=58) and MSCT group (n=61). The baselines characteristics of two groups were basically identical. For MSCT+SAAgroup, the accuracies of preoperative staging T, N, M and TNM were 89.66%, 79.31%, 100% and 77.59%, respectively; For MSCT group, the corresponding rates were 86.89%, 70.49%, 100% and 65.57%, respectively. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups (93.10% vs. 80.33%, P=0.041). The clinical staging (P=0.001), preoperative T staging (P=0.000), M staging (P=0.016), TNM staging (P=0.013) and serum level of SAA (P=0.029) were related to the selection of operative procedures when analyzing the relationship between the operative procedures and multiple clinicopathologic factors in lower rectal cancer. ConclusionCombinative assessment of 64 MSCT and SAA could improve the accuracy of preoperative staging, thus provide higher predictive coincidence rate to operative procedures for surgeon.
Objective To determine the influence of combinative assessment of transrectal ultrasound (TRUS) and serum amyloid A protein (SAA) on the assessment of preoperative staging selection of operative procedures in the middle and lower rectal cancer. Methods Prospectively enrolled 130 patients, who diagnosed definitely as middle and lower rectal cancer at West China Hospital of Sichuan University from June 2008 to February 2009 were randomly assigned into two groups with 65 participants, respectively. In one group named TRUS combined SAA group, both TRUS and SAA combinative assessment were made for the preoperative evaluation. In another group named TRUS group, only the preoperative TRUS was made. The preoperative staging and predicted operative procedures were compared with postoperative pathologic staging and practical operation program, respectively.Results Of 118 patients with rectal cancer were actually included into TRUS combined SAA group (n=59) and TRUS group (n=59). The baselines of characteristics of two groups were basically identical. For TRUS combined SAA group， the accuracies of preoperative T and N staging were 79.7% (47/59) and 77.8% (42/54) respectively; For TRUS group the corresponding rates were 86.4% (51/59) and 57.7% (30/52), respectively. There was no statistically significant difference of the accuracy of preoperative T staging （P=0.609） while preoperative N staging had statistical difference (P=0.027) between two groups. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups 〔96.6% (57/59) vs. 83.1% (49/59), P=0.015〕. The preoperative T staging was related to the selection of operative procedures (P=0.037) when analyzing the relationship between the operative procedures and the multiple clinicopathological factors in middle and lower rectal cancer. ConclusionCombinative assessment of TRUS and SAA could improve the accuracy of preoperative staging in middle and lower rectal cancer, thus provide higher predictive coincidence rate to operative procedures for surgeon.
Objective To determine the influence of combinative assessment of 64 multi-slice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) on the selection of operative procedures of upper rectal cancer in multi-disciplinary team. Methods Prospectively enrolled 110 patients, who were diagnosed definitely as upper rectal cancer (distance of tumor to the dentate line gt;7 cm) at West China Hospital of Sichuan University from August 2007 to October 2008, randomly assigned into two groups. In one group named MSCT+SAA group, both MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT group, only MSCT was made preoperatively. Then, the pooled data were analyzed for the correlative relationship between the choice of surgery strategy and clinicopathologic factors. Furthermore, the preoperative staging and predicted operative procedures were compared with postoperative pathologic staging and practical operative procedures, respectively. Results According to the criteria, 106 patients with upper rectal cancer were randomly assigned into MSCT+SAA group (n=52) and MSCT group (n=54). The baseline characteristics of two groups were statistically identical. When analyzing the proportion of multiple clinicopathologic factors in different operative procedures of upper rectal cancer, there were statistical differences in the preoperative N staging (P=0.003), M staging (P=0.022), TNM staging (P=0.003), serum level of SAA (P=0.005) and general category of tumor (P=0.027). For MSCT+SAA group the accuracies of preoperative staging T, N, M and TNM were 84.6%, 86.5%, 100% and 86.5%, respectively; For MSCT group the corresponding rates were 83.3%, 2.9%, 100% and 64.8%, respectively. There were statistically significant differences accuracies of preoperative N staging and TNM staging (P=0.005, P=0.009, respectively) in two groups. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups (96.2% vs. 81.5%, P=0.017). Conclusion Combinative assessment of 64 MSCT and SAA could improve the accuracy of preoperative staging, and thus provide higher predictive coincidence rate to operative procedures for surgeon.

Methods Ｔhe examination data of 110 patients diagnosed definitely as colon cancer in the West China Hospital of Sichuan University from Nov. 2007 to Nov. 2008 were studied prospectively, and randomly assigned into the MSCT+SAA group and MSCT group, respectively. Both MSCT and SAA combinative assessment were made for preoperative evaluation in MSCT+SAA group, while only MSCT was made preoperatively in MSCT group. Furthermore, the preoperative staging and prediction of operative procedures were compared with postoperative pathologic staging and practical of operative procedures, respectively. Results According to the inclusion criteria, 99 colon cancer patients were actually included into MSCT+SAA group (n=49) and MSCT group (n=50). The baseline characteristics of two groups were statistically identical. For MSCT+SAA group, The accuracies of preoperative staging T, N, M and TNM were 81.6%, 79.6%, 100% and 77.6%, respectively. For MSCT group, the corresponding rates were 82.0%, 60.0%, 98.0% and 62.0%, respectively. The difference of accuracies on staging N between two groups was observed statistically (χ2=4.498, P=0.034). There was also a statistically significant difference of the accuracy of prediction of operative procedures in MSCT+SAA group and MSCT group (95.9% vs. 82.0%, χ2=4.854, P=0.028). The preoperative staging N (P=0.008), M (P=0.010), TNM (P=0.009) and level of SAA (P=0.004) were related to the selection of operative procedures when analyzed the relationship between the operative procedures and multiple clinicopathologic factors in colon cancer. Conclusion The strategy of the combinative assessment of MSCT and SAA could advance the accuracy of preoperative staging, thus serve surgeon the more accurate prediction to surgery strategy in colon cancer.
ObjectivesTo explore the preoperative assessment method, operative approach and post-operative effect of intractable epilepsy.MethodsOne hundred and twenty five intractable epilepsy patients (85 males and 40 females) from Wuhan Brain Hospital during June 2009 to June 2017 were collected in this study. Their age ranged from 1 to 70 years old, with disease course of 1 ~ 32 years. All the patients underwent VEEG monitoring and MRI examination before operation, and MRS was performed when necessary. Some patients also received psychological assessment. According to the result of VEEG and MRI results, all the patients underwent operations under ECoG monitoring . The surgery effect was followed-up for more than 1 year.ResultsThe post-operative follow-up showed that satisfactory result was achieved in 50 cases, remarkable improvement in 29 cases, good effect in 23 cases, bad effect in 19 cases, and no improvement in 4 cases. The total effective rate of epilepsy surgery was 81.6%, and excellent rate was 41.6%. The effective rate was 81.3% in 80 cases of epileptogenic focus epileptic lesion resection, 87.5% in 40 cases of anterior temporal lobectomy (ATL), and 100% in 3 cases of functional hemispherectomy was, and good effect in the cases of pure cortical coagulation and VNS.ConclusionsThe surgical effects of ATL, epileptogenic focus resection and functional hemispherectomy are better than that of pure corpus callosotomy, multiple subpial transaction (MST), multiple subdural transversely fibrinectomy, VNS or cortical coagulation. So epileptogenic focus should be accurately located preoperatively, and it is better to choose resection operation in order to increase the surgical effect of intractable epilepsy.
