ABSTRACT
Objective To explore the factors affecting diagnosis accuracy on T stage of oral ultrasonic contrast agent examination on ulcerative gastric neoplasms.Methods Data from 82 patients were analyzed who were pathologically diagnosed as ulcerative gastric neoplasms ultrasounds data of oral ultrasonic contrast agent before surgery were compared to postoperative pathology,analysis had been done on influence of the lesion site,size of the T staging on ulcerative gastric neoplasms.Results The diagnosis accuracy rate of T stage on lesser curvature of stomach and gastric antrum were 91.3 ％ (21/23) and 85.7 ％ (24/28),compared with the pathological results were in good concordancy (Kappa =0.763,0.68,P ＜ 0.05).The accuracy rate of T stage on cardiac lesions was 68.0 ％ (17/25),compared with the pathological results consistency in general (Kappa =0.446,P ＜ 0.05).Further research on the effects of T stage accuracy would be necessary.The accuracy rate ofT staging on tumor size ≤ 5.0 cm group and ＞ 5.0 cm were 92.3 ％ (36/39) and 72.1％ (31/43),the difference was significant in two groups (x2 =5.591,P ＜ 0.05).Conclusion Oral ultrasonic contrast agent application is more accurate on lesser curvature of stomach,gastric antrum and lesions size ≤ 5.0 cm.
ABSTRACT
Objective To explore the value of oral ultrasonic contrast agent on preoperative T staging of gastric cancer.Methods 62 patients diagnosed with gastric neoplasms by operation and pathology were analyzed retrospectively.Patients were treated by oral ultrasonic contrast agent and conventional ultrasonography before surgery,two methods were compared with postoperative pathology.Results Oral ultrasonic contrast agent and conventional ultrasound detection rates of gastric neoplasms were 100.0 ％(62/62)and 64.5 ％ (40/62),The difference was significant between the two examination methods(x2 =24.369,P ＜ 0.05).The oral ultrasonic contrast agent and conventional ultrasound with T1,T4 staging accuracy rates were 85.7 ％(6/7),0,92.3 ％(36/39),59.0 ％(23/39),there were significant differences(both P ＜ 0.05).T2,T3 staging accuracy rate were 75.0 ％(3/4),0,83.3 ％(5/6),33.3 ％(2/6),the differences were not significant(P =0.143,P =0.242).Conclusion Oral ultrasonic contrast agent in preoperative T staging diagnosis has higher accuracy rate in gastric neoplasms,it could guide clinical rational therapy.It is worth promoting non-invasive,convenient means of stomach diseases census.
ABSTRACT
OBJECTIVE@#To explore the curative effect of pediatric chronic sinusitis and analyze its relative factors, so that the best treatment plan and operation time can be choose.@*METHOD@#Two hundred and twenty cases of pediatric chronic sinusitis were divided into 4 groups: group A with only simple chronic sinusitis, group B accompanied adenoid hypertrophy. Among group B, group B1 with no nasal cavity structural abnormalities but group B2 on the contrary. Group C accompanied only nasal cavity structural abnormalities. According to the documents, all patients were administered with standard and systematical three-stage treatment. The curative effect of each group was calculated and analyzed in each treated stage.@*RESULT@#After the first stage treated in 220 pediatric chronic sinusitis, a statistical significance of curative effect could be observed between group A and B, A and B1, A and B2, A and C (P 0.01). Ninety-four patients in group B were accepted the second stage treated: adenoidectomy after first treatment failed. There was a statistical significance of curative effect between group B1 and B2 (P < 0.01). Once the above management both failed, endoscopic sinus surgery (FESS) was carried out. The total effective rate of FESS was 89.65%.@*CONCLUSION@#The systemic, disciplinary medical management has some referred value in the treatment for children with chronic sinusitis. Adenoid hypertrophy and nasal cavity structural abnormalities are two relative factors of the curative effect in pediatric chronic sinusitis. The time and cost of therapy can be saved if adenoidectomy and FESS are done for cases with adenoid hypertrophy or (and) nasal cavity structural abnormalities with the systemic, disciplinary medical management simultaneously.
