Method Between March 2003 and October 2008, 89 patients (89 ears) underwent mastoidectomy in Department of Otolaryngology Head and Neck Surgery, West China Hospital of Sichuan University and in Department of Otolaryngology, Nuclear Industry 416 Hospital of Chengdu. The patients were randomly divided into two groups by simple randomization (trial group and control group). Forty-five patients in the trial group underwent the dressing change under otoendoscope, while 44 patients in the control group under the routine method. The ear drying rate and the ear drying time in the two groups were observed. Results The ear drying rate was 93.3% (42 dry ears)in the trial group, and was 90.9% (40 dry ears) in the control group; the difference between the two groups was not significant (Pgt;0.01). The ear drying time was (50.8±13.4) days in the trial group and was (60.7±12.2) days in the control groups; the difference between the two groups was significant (Plt;0.001). Conclusion Dressing change under the otoendoscope after mastoidectomy may not improve the ear drying rate but can shorten the ear drying time.
【摘要】 目的 了解原发性良性阵发性位置性眩晕（benign paroxysmal positional vertigo，BPPV）的双温试验及纯音测听结果临床特点。 方法 2009年6月—2010年6月诊断为原发性BPPV患者54例，于手法复位前行双温试验及纯音听阈测试，分析原发性BPPV患者的双温试验、纯音测听结果的临床特点。 结果 40例患耳无半规管轻瘫，其病程为（4.25±2.75）周，14例患耳半规管轻瘫，其病程为（9.21±5.85）周，两组间平均病程差异具有统计学意义（t=4.235，Plt;0.05）；39例后半规管BPPV中11例患耳半规管轻瘫，15例水平半规管BPPV中3例患耳半规管轻瘫，两组患耳半规管轻瘫发生率无统计学意义（χ2=2.679，Pgt;0.05）；39例后半规管BPPV中16例患耳听力下降，15例水平半规管BPPV中7例患耳听力下降，两组患耳纯音测听异常率无明显统计学差异（χ2=0.141，Pgt;0.05）。 结论 原发性后半规管BPPV与水平半规管BPPV半规管轻瘫及纯音听阈异常发生率相近，病程长者更易出现半规管轻瘫。【Abstract】 Objective To investigate the clinical features of results of bithermal test and pure tone test for patients with idiopathic benign paroxysmal positional vertigo (BPPV), and discuss strategies for prevention. Methods A total of 54 patients diagnosed to have BPPV during June 2009 to June 2010 underwent bithermal caloric test and pure tone test before particle repositioning maneuver. Then, we analyzed the clinical features of the test results. Results The course of 40 patients with canal paresis (CP) was (4.25±2.75) weeks, which had a significant difference from the course of 14 patients with CP in the abnormal side, which was (9.21±5.85) weeks (t=4.235, Plt;0.05). Among the 39 patients with posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV), 11 cases of canal paresis were found in the abnormal ear, and of the 15 patients with horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV), 3 cases of canal paresis were found. There was no statistical difference in the rate of canal paresis between the two groups of patients mentioned above (χ2=2.679,Pgt;0.05). Sixteen out of the 39 PSC-BPPV patients and seven out of the 15 HSC-BPPV patients had hearing loss (HL) in the abnormal ear with no statistical difference between the two groups of patients in the incidence of hearing loss (χ2=0.141,Pgt;0.05). Conclusion The incidence of CP and HL in the abnormal ear of patients with HSC-BPPV and PSC-BPPV is similar, and patients with long course of disease are more likely to have CP.
ObjectiveTo investigate the clinical manifestations, diagnosis, treatment and prognosis of Rosai-Dorfman disease (RDD) in nasal cavity and nasopharynx. MethodsWe retrospectively analyzed the clinical data of 4 patients with extranodal RDD admitted to the Department of Otolaryngology, Head and Neck Surgery of our hospital between November 2009 and August 2013. ResultsAll patients received complete surgical removal of the lesions. Histopathological examination showed that large histocytes had an abundant foamy cytoplasm containing ingested lymphocytes as a result of emperipolesis, and were strongly positive for S-100 and CD68 on immunohistochemical analysis, but negative for CD1a. All patients were followed up for 28 to 45 months (averaging 35 months), and no recurrence was observed during the follow-up period. ConclusionRDD is a rare disease, and the exact etiology and pathogenesis of RDD are not fully understood. There is no unified treatment plan recommended, and complete surgical removal of the lesions is an effective method. Minimally invasive surgery may be a good choice for treatment of this disease.
Objective To evaluate the diagnosis value of temporal Done high-resolution computed tornography (HRCT) in cholesteatoma. Methods There were 30 causes that had received the mastoid surgery because of cholesteatoma. Each patient’s mastoid plain films (Schuller’s and Mayer’s ) and HRCT had been taken and compared with each other and surgical findings and evaluated with health economic evaluation methods. Results The sensitivity rate in diagnosing cholesteatoma with HRCF was much higher than that with mastoid film (Plt;0.005). The more important benefit with HRCT was that it can afford the detail information in ear such as the ossicular chain, facial nerve canal, tympanic sinus, etc. which were basis for otologist in surgery to remove the focus thoroughly and reconstruct the middle ear function at the same time. In the view of health economic evaluation, HRCT is also much better than mastoid X-ray film. Conclusion HRCT should replace masloid Schuller’s and Mayer’s film in diagnosis cholesteatoma and HRCT should use as ordinary examination in chronic otitis media.
Objective To report our experience in living donor liver harvesting of right lobe grafts. MethodsThe data of 76 living donors of right lobe grafts hepatectomy between August 2007 and December 2008 were studied. Before operation, the graft size, remnant liver volume rate, fatty liver, middle hepatic vein type, and the level of portal hypertension of recipient were comprehensive assessed to determine whether harvested middle hepatic vein. The graft was harvested depending on the port vein and hepatic artery ischemia-line. B-ultrasound was used to definite the structure and branch of middle hepatic vein, and intraoperative cholangiography was performed to definite the structure and variation of bile duct. Donor operative time, intraoperative blood loss, postoperative hospital stay, levels of bilirubin, international normalized ratio （INR）, and ALT, and complications after operation were recorded. Results All the operations were successful. The operative time was (8.3±1.3) h, the blood loss was (325±127) ml without blood transfusion in operation. The ALT, INR, and bilirubin recovered on the 12th day. The most common complication in early post-operation was wound infection in 5 cases, 4 cases had cholestasis, 4 cases occurred cross-section bile leakage, and 11 cases occurred varying degrees of delayed gastric emptying in 4～7 d after operation, who were all alleviated by corresponding treatments. The hospital stay was 9～21 d (median: 14 d) after operation. Conclusion Preoperative evaluation of the hepatic anatomy and precise surgical procedure are crucial, which will help the development of graft harvesting and rehabilitation of donor.
Objective To explore the causes and prognosis of liver retransplantation. Methods The clinical data of 215 cases who had underwent liver retransplantation in Tianjin First Central Hospital between Nov. 26th 2003 and May. 26th 2012 were analyzed retrospectively for its causes and prognosis. Results Two hundreds and fifteen cases were enrolled， including 200 cases of 2 times liver transplantation， 14 cases of 3 times liver transplantation， and 1 case of 4 times liver transplantation. The major causes of the second liver transplantation were biliary complication （53.5%， 115/215） and primary non-function or dysfunction of liver graft （8.4%， 18/215）， and the major causes of the third liver transplantation were biliary complication （5/14） and hepatocellular carcinoma recurrence （2/14）. The liver graft survival rate of late liver retransplantation （at least 1 month after operation） was significantly higher than that of early liver retrans-plantation （less than 1 month after operation） for the second liver transplantation （P=0.005）. The liver graft survival rate of the second liver transplantation was significantly higher than that of the third liver transplantation （P=0.043）. Compared with biliary complication， cases of hepatocellular carcinoma recurrence （P=0.001） and primary non-function or dysfunction of liver graft （P=0.033） had lower graft survival rates， while cases of chronic failure of liver graft had a higher survival rate （P=0.037）. Conclusions Biliary complication is the main cause of liver retransplantation. The liver retransplantations which are performed less than 1 month after prior liver transplantation result in a relative low survival rate in reason of the increase of perioperative death. The prognosis of liver retransplantation for hepatocellular carcinoma recurrence is unacceptable， while cases of chronic failure of liver graft have optimal prognosis.
【摘要】目的 探讨肝移植术后肝动脉血栓的防治方法，以降低其发生率。方法 对52例（53例次）肝移植手术后发生肝动脉血栓的2例患者的临床资料进行回顾性总结。结果 该2例患者均为乙肝肝硬变合并巨块型肝癌，术中发现受体肝动脉内膜及外膜管壁硬化，血管弹性差，内外膜间隙较大，供、受体肝动脉直径稍有差距，致血管内膜对合不好，造成吻合口扭曲、皱折等，从而导致术后肝动脉血栓形成，2例患者术后均经彩超检查确诊。结论 对肝移植术后肝动脉血栓的形成应以预防为主，肝移植术后应常规用彩超监测肝动脉血流，一旦发现肝动脉血栓，应立即行肝动脉溶栓、取栓和重新吻合术。
With the widespread adoption of antiretroviral therapy, vast improvements in the life expectancy of individuals infected with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) were seen, and the liver disease of this population has become a leading cause of mortality. Although liver transplantation is as an effective treatment for end-stage liver disease, it remains in its nascent stage for the patients with HIV/AIDS in China, lacking standardized protocols and substantial clinical experience. Therefore, a “Multicenter expert consensus on perioperative management of liver transplantation in patients with human immunodeficiency virus infection” was formulated. This expert consensus aims to standardize and optimize the diagnosis and treatment process for liver transplantation in HIV-infected patients, providing systematic guidance for this procedure in China and fostering multidisciplinary collaboration and development in the field. This expert consensus clearly delineates the indications and contraindications for liver transplantation in HIV-infected patients, emphasizing comprehensive preoperative evaluations of both donors and recipients. These evaluations include infection control measures, immune function monitoring, and management of comorbidities. In terms of surgical procedures, strategies to prevent occupational exposure and intraoperative guidelines are outlined. Postoperatively, the focus is on antiviral therapy, individualized immunosuppression management, and vigilant monitoring of complications to ensure patient recovery and long-term survival. The long-term follow-up management prioritizes regular assessments of liver function, immune status, and HIV-related indicators to adjust treatment plans and enhance patient survival rates and quality of life. With the continuous enrichment of clinical experience and the progress of clinical research, this consensus will be continuously updated.
