Inflammatory myofibroblastic tumor (IMT) involving stomach, liver, biliary tract, and peritoneal mesentery was very rare, nonspecific clinical manifestations and laboratory examination were the main reasons for the difficult preoperative diagnosis of IMT. An IMT case involving multiple systems and multiple sites of the abdomen was presented, the CT and MRI imaging signs and pathological basis of IMT were illustrated, so as to strengthen the understanding of IMT for clinicians and radiologists.
Schwannoma originating from the common bile duct is rare. We presented a patient who was diagnosed with biliary cystadenoma preoperatively and pathologically confirmed as a choledochal Schwannoma, analyzed the CT and MRI imaging manifestations, and illustrated its anatomical and pathological basis, and to improve the understanding of clinicians and radiologists for choledochal Schwannoma.
目的 探讨二级医院神经内外科整合的可行性及优越性，观察组织化医疗模式的临床效果。 方法 将神经内、外科整合为一个一级临床科室——脑系科，建立完善的多学科一体化治疗的组织化医疗网络体系。入选重型颅脑外伤和脑出血患者共289例，其中2004年8月-2008年12月在脑系科住院的重型颅脑外伤、脑出血患者共147例接受组织化医疗模式治疗，作为治疗组；2001年1月-2004年8月分散在我院内科、外科住院的重型颅脑外伤、脑出血患者共142例接受传统常规治疗，作为对照组。比较观察两组患者的治疗效果。 结果 治疗组神经功能缺损评分、日常生活活动能力评分和GCS分别为7.47±5.24、59.74±15.56和13.72±1.06；对照组分别为16.18±9.89、34.00±10.54和10.84±1.58。两组比较，差异有统计学意义(Plt;0.05)。治疗组与对照组比较，临床治愈率提高55.64%，平均住院日缩短10.34 d，病死率降低21.26%，并发症降低20.15%，致残率降低20.24%。 结论 采用组织化医疗模式能明显改善患者预后，缩短住院时间，提高患者的生活质量，是适合我国基层医院神经内、外科危急重症的治疗模式，具有其可行性及优越性。
Objective To compare the intraoperative effects of computer navigation-assisted versus simple arthroscopic reconstruction of posterior cruciate ligament (PCL) tibial tunnel. Methods The clinical data of 73 patients with PCL tears who were admitted between June 2021 and June 2022 and met the selection criteria were retrospectively analysed, of whom 34 cases underwent PCL tibial tunnel reconstruction with navigation-assisted arthroscopy (navigation group) and 39 cases underwent PCL tibial tunnel reconstruction with arthroscopy alone (control group). There was no significant difference in baseline data between the two groups, including gender, age, body mass index, side of injury, time from injury to surgery, preoperative posterior drawer test, knee range of motion (ROM), Tegner score, Lysholm score, and International Knee Documentation Committee (IKDC) score between the two groups (P>0.05). The perioperative indicators (operation time and number of guide wire drillings) were recorded and compared between the two groups. The angle between the graft and the tibial tunnel and the exit positions of the tibial tunnel in the coronal, sagittal, and transverse planes respectively were measured on MRI at 1 day after operation. The knee ROM, Tegner score, Lysholm score, and IKDC score were evaluated before operation and at last follow-up. Results The operation time in the navigation group was shorter than that in the control group, and the number of intraoperative guide wire drillings was less than that in the control group, the differences were significant (P<0.05). Patients in both groups were followed up 12-17 months, with an average of 12.8 months. There was no perioperative complications such as vascular and nerve damage, deep venous thrombosis and infection of lower extremity. During the follow-up, there was no re-injuries in either group and no revision was required. The results showed that there was no significant difference in the exit positions of the tibial tunnel in the coronal, sagittal, and transverse planes between the two groups (P>0.05), but the angle between the graft and the tibial tunnel was significantly greater in the navigation group than in the control group (P<0.05). At last follow-up, 30, 3, 1 and 0 cases were rated as negative, 1+, 2+, and 3+ of posterior drawer test in the navigation group and 33, 5, 1, and 0 cases in the control group, respectively, which significantly improved when compared with the preoperative values (P<0.05), but there was no significant difference between the two groups (P>0.05). At last follow-up, ROM, Tegner score, Lysholm score, and IKDC score of the knee joint significantly improved in both groups when compared with preoperative values (P<0.05), but there was no significant difference in the difference in preoperative and postoperative indicators between the two groups (P>0.05). ConclusionComputer-navigated arthroscopic PCL tibial tunnel reconstruction can quickly and accurately prepare tunnels with good location and orientation, with postoperative functional scores comparable to arthroscopic PCL tibial tunnel reconstruction alone.
