[目的]探讨在关节镜下膝关节后侧腔室联合手术入路的重要性和可操作性。[方法]经过前内侧、前外侧和股骨髁切迹以及后内侧、后外侧和后纵隔内切口联合入路分别入镜、入器械，进行膝关节后侧腔室的探查和手术操作。[结果]216例（239膝）应用联合入路探查和治疗，其中5例膝因关节僵硬操作失败；175例膝用于治疗后侧腔室疾病，膝关节后侧腔室手术视野显著改善，探查和手术操作完善，均达到手术目的。1例膝内侧隐神经不全损伤，没有腘后神经、腓总神经、腘后血管、交叉韧带等重要组织损伤。[结论]膝关节后侧腔室病变较多，是检查和治疗的重要部位，并非“技术盲区”。这种联合手术入路，手术风险低，具备可操作性，可以提高手术效率和质量，可作为膝关节镜下常规手术入路。     

Total pancreatectomy with islet autotransplantation: an overview

Pain control is one of the most challenging aspects in the management of chronic pancreatitis. Total pancreatectomy can successfully relieve the intractable abdominal pain in these patients but will inevitably result in insulin-dependent diabetes. Islet autotransplantation aims to preserve, as far as possible, the insulin secretory function of the islet cell mass thereby reducing (or even removing) the requirement for exogenous insulin administration after a total pancreactomy. Despite the relatively small number of centres able to perform these procedures, there are important technical variations in the details of their approaches. The aim of this review is to provide details of the current surgical practice for total pancreatectomy combined with islet autotransplantation, and outline the potential advantages and disadvantages of the variations adopted in each centre.     

Quality of life after total mesorectal excision for rectal cancer

BACKGROUND: After total mesorectal excision for rectal cancer, many surgeons try to avoid an abdominoperineal resection (APR) by performing a transanally double stapled low colo-rectal anastomosis (LRA), frequently without a pouch. This policy is mainly based on the assumption that the quality of life after such LRA is higher than after APR. It has been suggested that a better functional outcome and therefore a higher quality of life might be achieved by a colo-anal J-pouch anastomosis (CPA). The aim of this study was to assess quality of life among disease-free survivors after APR, LRA and CPA. METHODS: The charts of 301 consecutive patients who had undergone surgery for cancer in the middle or lower third of the rectum were analysed. Two hundred four patients were eligible for inclusion. The quality of life among these patients was assessed using one generic (EQ-5D) and two disease-specific questionnaires (EORTC QLQ-C30 and EORTC QLQ-CR38). RESULTS: The response rate was 82%. The median follow-up was 31 months. Overall, quality of life was good but CPA patients had better quality of life scores than APR and LRA patients. This difference was not only due to the better functional outcome but also to the lower incidence of disturbed micturition and sexual problems in the CPA group. CONCLUSION: The quality of life after colo-anal J-pouch anastomosis is better than after abdominoperineal resection (APR) and low colo-rectal anastomosis (LRA). The quality of life after APR is similar to that after LRA.     

A comparison of segmental vs subtotal/total colectomy for colonic Crohn''s disease: a meta-analysis

OBJECTIVE: Using meta-analytical techniques the present study evaluated differences in short-term and long-term outcomes of adult patients with colonic Crohn's disease who underwent either colectomy with ileorectal anastomosis (IRA) or segmental colectomy (SC). METHODS: Comparative studies published between 1988 and 2002, of subtotal/total colectomy and ileorectal anastomosis vs segmental colectomy, were used. The study end points included were surgical and overall recurrence, time to recurrence, postoperative morbidity and incidence of permanent stoma. Random and fixed-effect meta-analytical models were used to evaluate the study outcomes. Sensitivity analysis, funnel plot and meta-regressive techniques were carried out to explain the heterogeneity and selection bias between the studies. RESULTS: Six studies, consisting of a total of 488 patients (223 IRA and 265 SC) were included. Analysis of the data suggested that there was no significant difference between IRA and SC in recurrence of Crohn's disease. Time to recurrence was longer in the IRA group by 4.4 years (95% CI: 3.1-5.8), P < 0.001. There was no difference between the incidence of postoperative complications (OR = 1.4., 95% CI 0.16-12.74) or the need for a permanent stoma between the two groups (OR = 2.75, 95% CI 0.78-9.71). Patients with two or more colonic segments involved were associated with lower re-operation rate in the IRA group, a difference which did not reach statistical significance (P = 0.177). CONCLUSIONS: Both procedures were equally effective as treatment options for colonic Crohn's disease however, patients in the SC group exhibited recurrence earlier than those in the IRA group. The choice of operation is dependent on the extent of colonic disease, with a trend towards better outcomes with IRA for two or more colonic segments involved. Since no prospective randomised study has been undertaken, a clear view about which approach is more suitable for localised colonic Crohn's disease cannot be obtained.

中药熏洗治疗膝关节骨性关节炎的Meta分析

为运用循证医学方法对中药熏洗治疗膝骨性关节炎（OA）的临床疗效及安全性进行系统评价和Meta分析。全面收集了中药熏洗治疗OA的文献资料。在严格质量评价基础上，对研究结果进行定性分析。合并各篇优、良为阳性结果，中、差为阴性结果。利用RevMan4．1软件对多个研究结果的总体疗效进行固定效应模型的Meta分析，并进行敏感性分析。用漏斗图表示发表性偏倚。结果显示，中药熏洗治疗OA的效应值OR=2．68.95％可信区间为[1．82，3．95]；敏感性分析显示效应值稳定；漏斗图图形不对称；无中药熏洗不良反应的报道。表明中药熏洗治疗OA有一定的疗效，由于漏斗图提示存在发表性偏倚，加上现有临床研究存在的方法学问题，现在的研究结论有一定的局限性，欲得出公认的结论，尚有待进行设计严谨的多中心、随机对照试验。
