    Objective To investigate and evaluate the clinical manifestation, classification, surgical management and postoperative adjuvant therapy of thymic carcinoid, so as to improve the knowledge of the disease. Methods From January 1980 to January 2006, the outcome of surgery and follow-up of 18 cases of thymic carcinoid surgically intervened were retrospectively analysed. In this series, there were 2? exploratory thoracotomy, 2 partial or incomplete resection and 14 complete resections, which included 2 superior vena cava removal and reconstruction. The survival probabilities were calculated by the life tables, and a multivariable analysis of prognosis factors for thymic carcinoid was carried out using Cox regression model. Results Two patients who underwent exploratory thoracotomy died within one year and two years postoperatively respectively, 2 with partial or incomplete resection obtained temporary symptomatic improvement, 1 of 14 performed complete resections associated with Cushing’s syndrome died of septicemia in two weeks postoperatively, and the other 13 cases were in good condition by follow-up of 5 months to 15 years. The survival rate of 3, 5 and 10 years were 72.6%, 60.5% and 40.3%, respectively. According to Cox regression analysis, the factors of influence upon prognosis included lymph node metastasis(P=0047), pathological type(P=0.000), mode of resection (P=0.000) and postoperative adjuvant treatment(P=0018). Conclusion The thymic carcinoid is different from thymoma or thymic carcinoma, and there exist some difficulty in differential diagnosis. It is divided into typical and atypical thymic carcinoid in pathology, There are obvious differences in clinical manifestation and prognosis between typical and atypical carcinoid. The atypical thymic carcinoid has higher malignancy, frequent recurrence or metastasis, and poor prognosis. Complete resection of tumor with the involved surroundings could improve the long-term survival. The adjuvant radiotheraphy and chemotheraphy postoperatively would be benefit to the patients.

  • Clinical features and prognosis analysis of acute isolated corpus callosum infarction

    Objective To investigate the clinical features and prognosis of acute isolated corpus callosum infarction. Methods The clinical and imaging data of patients with acute isolated corpus callosum infarction diagnosed in the Department of Neurology of Beijing Geriatric Hospital and the Department of Neurology of China-Japan Friendship Hospital from February 2017 to February 2021 were retrospectively selected. Patients were divided into groups according to infarction location, infarction size and prognosis. According to the infarction location, the patients were divided into single-site lesion group and multi-site lesions group. According to the infarction size, the patients were divided into large lesion group and small lesion group. According to the prognosis, the patients were divided into good prognosis group and poor prognosis group. The clinical characteristics, etiology and prognosis of these diseases were observed and analyzed. Results A total of 52 patients were included. Among them, there were 32 males (61.5%) and 20 females (38.5%), with an average age of (65.4±7.1) years. The most common risk factors were hypertension (44 cases, 84.6%), hyperlipidemia (32 cases, 61.5%), and diabetes (28 cases, 53.8%). The most common infarction site was splenium in the single-site lesion group (24 cases, 46.2%). The vast majority of patients (92.3%) had nonspecific clinical symptoms, and only 4 (7.7%) had corpus callosum disconnection syndrome. In the TOAST etiological classification, Large-artery atherosclerosis (LAA) was the most common (25 cases, 48.1%), followed by small-artery occlusion (14 cases, 26.9%), the responsible vascular lesions were the most common in the P1/P2 segment of posterior cerebral artery (10 cases) and the A1/A2 segment of anterior cerebral artery (9 cases). There was no significant difference in etiology between the groups with different infarction location and the groups with different infarction size (P>0.05). Forty-four cases (84.6%) had a good prognosis, and 8 cases (15.4%) had a poor prognosis. Combined with multiple risk factors, multiple involvement of lesions and large infarction size were associated with poor prognosis (P<0.05). Conclusions Acute isolated corpus callosum infarction is a rare type of ischemic stroke, with the most common involvement of splenium. Its clinical manifestations are mostly nonspecific, and a few may be manifested as disconnection syndrome. The etiology is mostly LAA, and the overall prognosis of such patients is good, and the poor prognosis may be related to the combination of multiple risk factors and the wide range of infarcts.

  • Surgical Treatment for Non-malignant Esophageal-tracheal/bronchial Fistula

    ObjectiveTo investigate clinical characteristics and surgical treatment of patients with non-malignant esophageal-tracheal/bronchial fistula.?Methods?We retrospectively analyzed clinical data of 12 patients with non-malignant esophageal-tracheal/bronchial fistula who underwent surgical repair in Peking Union Medical College Hospital from January 2002 to October 2011. There were 6 males and 6 females with a mean age of 49.8 years (ranging from 32 to 72 years). There were 7 patients with esophagotracheal fistula,1 patient with esophagobronchial fistula,2 patients with gastro-bronchial fistula after esophagectomy for esophageal cancer,and 2 patients with esophageal diverticulum bronchial fistula. Nine patients underwent surgical repair via right thoracotomy approach,and 3 patients via left thoracotomy approach. Seven patients underwent esophageal fistula and tracheal fistula repair,1 patient underwent esophageal fistula and bronchial fistula repair,2 patients underwent gastric fistula and bronchial fistula repair,1 patient underwent esophagectomy, gastroesophageal anastomosis and left lower lobectomy, and 1 patient underwent esophageal diverticulum repair and left lower lobectomy.?Results?All the patients recovered well from surgery with no perioperative complication or in-hospital death,and resumed oral intake 7-10 days after surgery. Three months to 1 year postoperatively, regular examinations including upper gastroenterography and fibrobronchoscopy found no sign of tracheal/bronchial stenosis or esophageal stenosis,and no patients needed stent implantation or dilatation treatment. All the patients were followed up from 3 months to 10 years and had a good quality of life during follow-up.?Conclusion?Excluding malignant etiology and determining the exact fistula location are key points of clinical diagnosis for esophageal-tracheal/bronchial fistula. Adequate preoperative nutritional support and 1-stage surgical repair can lead to satisfactory clinical outcomes.
