A retrospective study of 65 cases of huge sacrococcygcal teratomas were surveyed. The long term functional prospect of the benign tumor was excellent. The characteristics of the normal and pathological anatomy of the pelvic floor were mentioncd. Based on these, the authors described some personal experiences of the procedures, and discussed some problems of the reconstruction of the pelvic floor.
目的探讨磁共振成像(MRI)检查对骶前囊肿术前诊断的价值。方法回顾性分析2010年2～9月期间南京市中医院收治的12例骶前囊肿患者的临床资料。患者术前均行肛门指检、腔内B超及MRI检查，以术后病理检查结果为标准，比较术前MRI检查与肛门指检及腔内B超检查的结果。结果术前MRI检查结果中10例与病理检查结果相符，2例与病理结果基本相符； 而肛门指检及腔内B超检查结果中与病理检查结果相符者为6例。结论MRI检查能多方位显示骶前囊肿本身特点及其周围的解剖结构，对提高手术的成功率有重要指导意义。
ObjectiveTo explore the related factors for postoperative fever in patients with ovarian mature teratoma. MethodsA case-control study was conducted, and the subjects were patients with ovarian mature teratoma who had undergone surgical treatment in the hospital where the author works during September 2010 to August 2013. Eighty-eight cases diagnosed as ovarian mature teratoma with postoperative fever were included in the case group and 100 cases diagnosed as ovarian mature teratoma without postoperative fever were included in the control group. The medical records of the two groups were analyzed retrospectively. ResultsHospital stay of the case group and the control group was (5.68±1.53) and (3.28±1.18) days, respectively. The laparotomy ratio was 38.64% (34/88) and 20.00% (20/100); the tumor diameter was (6.65±3.07) cm and (5.33±1.87) cm, respectively. The difference in the above indicators between the two groups was significant (P<0.05). There was no significant difference in age, body mass index, body temperature before surgery, preoperative CA199, preoperative tumor torsion, preoperative antibiotics, tumor characteristics (bone, multi-room, bilateral), operative time, blood loss, pelvic adhesions, placing drainage tubes between the two groups (P>0.05). ConclusionPostoperative fever of ovarian mature teratoma is related to surgical approach and tumor size. Hospital stay is associated with postoperative fever. We should strengthen the gynecological examination. Early detection and reasonable choice of surgical procedures can reduce the incidence of postoperative fever, thus shorten the hospital stay and save medical resources.
ObjectiveTo explore the differences in ultrasonographic features of testicular teratoma and yolk sac tumor (YST) in children.MethodsA total of 44 patients were selected, including 30 with testicular teratoma and 14 with YST, whose diagnoses were confirmed by surgery and pathology in West China Second University Hospital, Sichuan University from January 2015 to June 2019. The differences in ultrasonograhic characteristics of the two groups were compared, such as the size, location, internal echo, composition, and blood supply of the tumors.ResultsThe mean value of maximum diameters of testicular teratomas was (24.25±12.13) mm and that of YSTs was (29.71±18.75) mm, with no statistically significant difference between the two groups (F=0.531, P=0.383). In terms of the compositions of the tumors, cystic-solid lesions were the most common in testicular teratomas (17/30), followed by solid lesions (8/30) and cystic lesions (5/30); while solid lesions were the most common in YSTs (12/14), followed by cystic-solid lesions, and cystic lesions did not appear. The difference in the compositions of tumors was statistically significant between children’s testicular teratomas and YSTs (P=0.001), especially in the proportion of solid lesions. In terms of Adler grade of blood flow, there were 9 cases of Adler 0, 10 cases of Adler 1, 10 cases of Adler 2, and 1 case of Adler 3 in testicular teratomas, while there were 0 case of Adler 0, 1 case of Adler 1, 4 cases of Adler 2, and 9 cases of Adler 3 in YSTs. The difference in the blood supply was statistically significant between children’s testicular teratomas and YSTs (P<0.001). Testicular teratomas tended less to behave as Adler 3, while Adler 3 was the most common in YSTs. There was no statistically significant difference in other ultrasonic features, like the location, internal echo, or the existence of calcification (P>0.05).ConclusionsUltrasound has a certain meaning for the differential diagnosis of testicular teratoma and YST in children. By comparing the solid component and the blood supply of the tumor, it is helpful for enhancing the diagnostic confidence of sonographer.
