Objective To assess the dagnostic value of computed tomography(CT) for recurrent carcinoma of larynx after operation. Methods 45 CT cases of recurrent carcinoma of larynx were analysed retrospective and were compared with pathology results.Results CT was capable of demonstrating the existence,border and range of the recurred tumor and showing the information about inetastasis in lymph node of neck,the involved throat space and the invaded blood vcsscls in cervical.Conclusion CT is an cxact,rcliable and convenient method to evaluate the recurrence of larynx carcinoma,and is helpful to make therapy planning.

The lungs are naturally irregular and asymmetrical organ in anatomy. The conducting bronchial trees in the lungs display complex self-similar structure. We have established the host mesh coordinates of the right lung on the basis of the anatomical data from the literature. A three-dimensional fractal model of the conducting airways was set up by calculating the coordinates of the mass centers of the divided blocks, searching the branch direction and determining branch lengths with the use of the drawing tool OpenGL. Specific data of the lengths at various grades, branching angles, and capillary diameters were obtained. As a result, the computed data were identical with those of the existing statistical data. The fractal covering dimensionality obtained in the computation of this model was 2.19, which is very close to the ideal dimensionality, 2.17, from the literature. The present model has laid the foundation for further research of the gas diffusion and transfer performance in the lungs using the fractal concept, and furthermore, it helps to save the computer memories and fastening the graphic transfer.

OBJECTIVE To discuss the therapeutic effect of one stage surgical treatment in the multiple primary hypopharyngeal and cervical thoracic esophageal carcinoma.METHODS The thoracoscopy group: dissecting the esophagus and mediastinal lymph node assisted with thoracoscope, and then opened abdominal cavity to make gastric tube. Head and neck group: doing the cervical lymph node dissection, total laryngectomy, total hypopharyngectomy and total esophagectomy, and then anastomosis of the pharynx with gastric tube. All cases were received conventional radiotherapy and chemotherapy after operation.RESULTS All the cases in this group were successfully underwent the one stage operation. The postoperative complications were pulmonary infection in 3 cases, pleural effusion in 2 cases and tracheal tear in one case. No anastomotic fistula or postoperative deaths occurred. The 3 and 5 year survival rates were 63.6% and 50.0% respectively.CONCLUSION It should take necessary examinations of cervical thoracic esophagus to prevent missing the multiple primary carcinoma of the hypopharyngeal carcinoma. The total laryngectomy, total hypopharyngectomy and total esophagectomy, and anastomosis of the pharynx with gastric tube for multiple primary hypopharyngeal and cervical thoracic esophageal carcinoma is a feasible and active treatment method.

BACKGROUND:
The aim of this study was to analyze the incidence of lower limb deep venous thrombosis (DVT) and the corresponding coagulation status in severe patients after thoracic surgery.
METHODS:
Severe patients after thoracic surgery who received mechanical prophylaxis of lower limb DVT between July 2016 and June 2018 were analysed retrospectively. Their general information, disease species, surgical treatment, and coagulation index were reviewed.
RESULTS:
Fifty patients were finally included. There were 34 male and 16 female, aging from 22 to 80 years. The incidence of DVT was 22.0%, all of them were isolated calf DVT. The incidence was 29.4% in male patients, while 6.3% in female; 23.5% in malignant diseases and 18.6% in benign. All coagulation index presented no statistical difference between patients with and without DVT, except activated partial thromboplastin time (APTT).
CONCLUSIONS
Even on the basis of adequate mechanical prophylaxis, lower limb DVT is common in severe patients after thoracic surgery. Meanwhile, male patients and malignant diseases are more suscepted.

BACKGROUND:
Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE).
METHODS:
This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE.
RESULTS:
This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively.
CONCLUSIONS
Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.
