OBJECTIVESTo summarize the clinical results in the treatment of spinal tuberculosis with debridement, bone grafting and anterior fixation and to evaluate the safety and the value of this procedure.

METHODSFrom June 1997 to May 2001, 18 patients with spinal tuberculosis were treated using anterior debridement, autograft of bone and primary internal instrumentation. They were 8 men and 10 women, aged from 25 to 59 years (mean 41 years). The degree of kyphosis before surgery was 27.0 degrees to 75.5 degrees (mean 47.5 degrees +/- 11.4 degrees ). The involved spines included cervical spine (1 patient), thoracic spine (10), thoracic-lumbar spine (2), and lumbar spine (5). Average 2.8 intervertebral bodies in each patient were afflicted with tuberculosis disease. Spinal fusions were done with iliac bone grafts.

RESULTSAll patients were followed up for an average of 25 months. No deep wound infection and sinus were observed after surgery. The grafted bones were fused in all patients with an average time of 3.6 months. The degree of spine kyphosis correction was 32.7 degrees +/- 8.3 degrees, and 3.2 degrees +/- 2.8 degrees was lost on average in the late stage.

CONCLUSIONAnterior instrumentation for spinal tuberculosis could stabilize the spine, correct kyphosis and fuse the grafted bone.

Objective     To evaluate the influence of resection status, pathological type, pathological stage and postoperative adjuvant therapy on prognosis of surgically treated thymic carcinoma. Methods     In this retrospective study, 56 patients with surgically treated thymic carcinoma in the Department of Thoracic Surgery, Peking Union Medical College Hospital from January 2005 to December 2015 were enrolled. There were 30 males and 26 females aged 52.1±11.5 years ranging from 22 to 81 years. The survival curve was performed by Kaplan-Meier method. The prognostic factors affecting overall survival (OS) and disease-free survival (DFS) were analyzed by one-way analysis of variance (ANOVA). Results     R0 resection was performed in 37 patients (67.9%), and other resections in 19 (32.1%); 13 patients suffered thymic carcinoma with Masaoka stage Ⅰ-Ⅱ, 26 Ⅲ, and 17 Ⅳ. Low-grade thymic carcinoma was found in 42 patients, and high-grade in 14. Postoperative radiotherapy, chemotherapy and chemoradiotherapy were performed on 17, 12 and 18 patients respectively and 9 patients were untreated. Forty-one patients was followed up for 1 to 10 years, and the follow-up rate was 73%. The 1-, 3- and 5-year OS rates were 93%, 74% and 61%, respectively. Resection status and pathological stage affected OS. Postoperative radiotherapy after R0 resection affected DFS, but did not affect OS. Conclusion     Most patients with thymic carcinoma after surgery can survive for a long period, and R0 resection is the most important prognostic factor of thymic carcinoma. Postoperative radiotherapy after R0 resection in patients with Masaoka stage Ⅱ-Ⅲ is recommended.

（正）食管癌是我国高发的消化道恶性肿瘤，目前食管癌的治疗仍然以手术方式为主，化疗、放疗等方法为辅[1]。食管癌手术切除术式经过多年的演变，从开放左胸一切口、二切口，发展到开放右侧进胸二切口、三切口。随着高清晰度胸腔镜、高科技内镜手术器械和先进麻醉技术的应用，微创食管切除手术技术得到迅猛的发展并趋于成熟。胸腔镜手术具有创伤小、恢复快等优势，已经在胸外科手术中得到了充分肯定[2-3]。本视频旨在展示胸腹腔镜联合食管癌手术的手术入路和操作要点。

ObjectiveTo investigate the association between spontaneous portosystemic shunt （SPSS） and hepatorenal syndrome （HRS） in patients with liver cirrhosis. MethodsA retrospective analysis was performed for 93 patients with SPSS from Dezhou Hospital， Qilu Hospital of Shandong University， from January 2015 to January 2022， and the patients were followed up for 12 months with the onset of HRS as the observation endpoint. According to the presence or absence of HRS， the 93 patients with SPSS were divided into HRS group with 38 patients （40.86%） and non-HRS group with 55 patients （59.14%）， and the two groups were compared in terms of clinical data， laboratory data， complication， and shunt diameter. Based on the maximum shunt vein diameter of 1.5 cm， the 93 patients with SPSS were divided into high shunt group with 52 patients （55.91%） and low shunt group with 41 patients （44.09%）， and with the onset of HRS as the observation endpoint， the two groups were compared in terms of the incidence rate of HRS and survival time curve. The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance between two groups， and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic （ROC） curve was used to predict cut-off values， the Kaplan-Meier curve was used for comparison of survival time， and the Log-rank test was used to compare the differences in survival curves. The multivariate Cox regression analysis was used to investigate risk factors. ResultsCompared with the non-HRS group， the HRS group had significant increases in Child-Pugh score， Child-Pugh class， MELD score， serum creatinine， blood urea nitrogen， alanine aminotransferase， aspartate aminotransferase， maximum shunt vein diameter， the incidence rates of hepatic encephalopathy and spontaneous bacterial peritonitis， and the degree of ascites， as well as significant reductions in main portal vein diameter， serum sodium and albumin （all P<0.05）. Compared with the low shunt group， the high shunt group had a significant increase in the incidence rate of HRS （51.92% vs 26.83%， χ²=5.974， P=0.015） and a significant reduction in the time to the onset of HRS （Log-rank P=0.033）. A maximum shunt vein diameter of >1.5 cm （hazard ratio ［HR］=1.123， 95% confidence interval ［CI］： 1.041‍ ‍—‍ ‍1.211， P=0.003）， an increase in MELD score （HR=1.205， 95%CI： 1.076‍ ‍—‍ ‍1.437， P=0.039）， a reduction in serum albumin （HR=0.890， 95%CI： 0.814‍ ‍—‍ ‍0.974， P=0.011）， an increase in the degree of ascites （HR=2.099， 95%CI： 1.066‍ ‍—‍ ‍4.130， P=0.032）， and spontaneous bacterial peritonitis （HR=2.259， 95%CI： 1.020‍ ‍—‍ ‍5.003， P=0.045） were independent risk factors for the onset of HRS in SPSS patients. ConclusionThere is an association between SPSS and HRS， and shunt diameter >1.5 cm was an independent risk factor for HRS in SPSS patients， which should be taken seriously and require early intervention in clinical practice.
