Objective To analyze the outcome in advanced age patients with obstruction of the left colonrectal cancer treated by intraoperative cavage method.Methods From 1998 and 2004,37 senile patients with acute obstruction for cancer underwent surgery.The patients were treated with intraoperative lavage,resection and primary anastomosis.Results All patients,no anastomotic leakage occurred.The patients got a well recovery post-operation.Conclusion One-stage emergency surgery for left obstructing colonic cancers is safe with the regard of intraoperative lavagation methods.

Objective To explore the feasibility and clinical efficacy of entirely mastoscopic axillary lymph node dissection for patients with breast cancer. Methods To analyze the clinical data and the procedure of the Breast cancer cases with entirely mastescopic axillary lymph node dissection. Results All the operations of those cases re-ceived entirely mastoseopic axillary lymph nodes dissection were successful, the average operating duration was 97min,and average of 5 ~ 14 lymph nodes were removed;2 cases had the positive lymph node. The procedure of those operations went well ,and there was no operation complication. After the operation the shoulder mobilization had unlim-ited, and no cancer cell was transplanted in operations holes. Conclusion Entirely mastoscopic axillary lymph node dissection can be carried out in grass-root hospitals and can be taken as one of the usual operation methods.

Prominent problems of clinical teaching in Tibet University school of medicine were analyzed and countermeasures were proposed from aspects of management system construction, facul-ty construction, curriculum construction, base construction and quality evaluation system construction. The aim was to increase students' opportunity, enhance students' learning interest and improve stu-dents' ability of analysis and problem solving so as to improve the practical effects of clinical teaching. All countermeasures taken above laid the foundation for future clinical work and provided help for clinical medical personnel in Tibetan border areas.

Objective:To develop a grading system for necrosis of pedicled flaps in reconstruction of foot and ankle, and to verify its effectiveness and repeatability.Methods:A retrospective observational study was conducted. A total of 40 necroses of foot and ankle pedicled flaps were selected by 2 senior surgeons based on the flap surgery performed by the same surgical group in Department of Orthopaedic Surgery, the 920 Hospital of Joint Logistic Support Force of PLA from January 2010 to January 2022. A grading system for pedicled flap necrosis was proposed by a working group and the 40 necrotic flaps were graded. The coincidence rate was calculated to evaluate the effectiveness of the grading system through correlation studies between grading and clinical treatment. One photo of a typical postoperative necrotic flap was collected from each of the 40 flaps. Then 5 extramural surgeons were asked to grade the necroses shown on the photos according to the proposed grading system. Moreover, weighted Kappa analysis was performed on the results of proposed grading system and also on the standard grading currently in use, to evaluate the repeatability of the proposed grading system. Evaluated data were expressed by Mean±SD, and the coincidence rate was expressed by percentage. The reproducibility was studied by weighted Kappa analysis.Results:Of the 40 necrotic flaps, 7 flaps were classified in Grade I, 16 in Grade Ⅱ, 12 in Grade Ⅲ and 5 in Grade IV. In comparison with the actual treatment methods, the overall coincidence rate of the grading system was 92.5%. It indicated that the proposed grading system could effectively guide the selection of a treatment procedure. The average weighted Kappa coefficient of surgeons was at 0.628 with a 95% confidence interval (95%CI) between 0.460-0.796, which was strongly consistent with the standard of the grading system currently in use.Conclusion:The grading system for necrosis of pedicled flap in reconstruction of foot and ankle proposed in this study is simple and clear. It is able to effectively guide the treatment of flap necrosis. The preliminary validation shows that the classification system has good repeatability.
