Objective To evaluate the curative effectiveness and safety of transanal endoscopic microsurgery (TEM) vs. radical surgery (RS) for the patients with rectal malignant tumor, and to provide information for clinical research and practice. Methods Through computer searching The Cochrane Central Register of Controlled Trials, PubMed, OVID, CBM and CNKI from inception to April 2010, and hand searching relevant journals including Chinese Journal of Surgery and Chinese Journal of Evidence-Based Medicine, the randomized controlled trails (RCTs) and non-randomized controlled trails (NRCTs) comparing TEM with RS for rectal malignant tumor were collected. Data were extracted and evaluated by two reviewers independently according to the Cochrane Handbook for Systematic Reviews. Meta-analyses were conducted using the Cochrane collaboration’s software RevMan 5.0. Results One RCT and four NRCTs met the selection criteria, involving 929 patients. The methodological quality of all trials was low with possibility of bias. The meta-analyses showed that: a) Three studies reported local recurrence in T1 stage patients. There was a significant difference in local recurrence between the two groups (OR=12.61, 95%CI 2.59 to 61.29, P=0.002); b) Two studies reported disease-free survival in T1 stage patients. There was no significant difference between the two groups in disease-free survival (OR=1.12, 95%CI 0.31 to 4.12, P=0.86); c) Three studies reported overall survival in T1 stage patients. There was no significant difference between the two groups (OR=1.09, 95%CI 0.57 to 2.08, P=0.80); and d) Three studies reported postoperative complications in T1 stage patients. There was a significant difference between the two groups in terms of complications (OR=0.05, 95%CI 0.02 to 0.10, Plt;0.00001). Conclusion For T1 stage patients, TEM is associated with less injury of tissue, less operative bleeding, short duration of hospital stay, and low incidence of postoperative complications. The disease-free and overall survivals are comparable to those of RS, but the local recurrence rate is higher. The role of TEM in T2 stage patients is still under discussion. However, the trails available for this systematic review are of lower methodological quality, and bias may exist due to NRCTs. Therefore, more high quality RCTs are required.
目的：探讨难治性鼻出血临床治疗的选择。方法:回顾性分析本科2005年11月～2006年11月收治的难治性鼻出血82例的临床资料。结果:均治愈。其中73例在鼻窦内窥镜下行局部填塞;4例行鼻中隔矫正术;3例鼻腔血管瘤中1例行下鼻甲部分切除术,另2例行双极电凝术。2例因鼻出血严重,经反复前鼻孔或前后鼻孔填塞都无效后,采用颈外动脉血管结扎术。结论:针对难治性鼻出血的不同原因、不同出血部位，应选择不同的治疗方法。
目的：探讨鼻前庭囊肿的最佳治疗方法。方法:在鼻内镜下辅以鼻窦电动切割器，对32例患者行鼻前庭囊肿揭盖术。结果:32例均获治愈，无1例并发症，随访1年以上，均未见囊肿复发和并发症。结论:鼻内镜下辅以鼻窦电动切割器行鼻前庭囊肿揭盖术，具有手术精确、时间短、创伤小、愈合快等微创手术优点，值得推广。
Objective To investigate the best management in treating relapsed biliary calculi after endoscopic sphincterotomy (EST).Methods The clinical data of 96 patients with relapsed biliary calculi after EST in our hospital from February 1999 to February 2009 were retrospectively analysed. The patients were grouped into two groups by the size of calculi under magnetic resonance cholangiopancreatography: surgical group (the size of calculi was bigger than 1.0 cm) in 79 cases and non-surgical group (the size of stone was smaller than 1.0 cm and the patients were performed EST again) in 17 cases. The relapsed biliary calculi rate between two groups were compared. Results In the surgical group, the 79 patients (82.29%) were performed common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis. In the non-surgical group, the 17 patients (17.17%) were performed EST again. The relapsed biliary calculi rate was 2.63% in the surgical group, 70.59% in the non-surgical group. There was marked difference in the relapsed biliary calculi rate between surgical group and non-surgical group (Plt;0.05). Conclusion The operation treatment is the best way for relapsed biliary calculi after EST, and has good curative effect. The best manner of operation treatment is common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis.
目的 探讨经胸骨前径路内镜甲状腺手术的方法及其临床效果。 方法 采用经胸骨前径路内镜甲状腺手术治疗24例甲状腺良性肿瘤患者，并进行定期随访。 结果 23例手术顺利完成，1例因术中快速冰冻病理诊断为乳头状甲状腺癌而追加常规甲状腺癌根治术。平均手术时间为150 min，术中平均出血量30 ml。2例出现皮下气肿，4例出现胸部皮肤麻木。无喉返神经及甲状旁腺损伤,无术后出血、甲状腺危象等并发症出现。随访1~6个月，所有患者对美容效果非常满意，无近期肿瘤复发者。 结论 经胸骨前径路内镜甲状腺手术是一种美容效果较好的手术方法，手术操作空间的建立和术中控制出血是该术式的两大关键技术。
ObjectiveTo discuss the indication, therapeutic effect, complication of endoscopic surgery for pancreatic pseudocyst and its defect and merit.MethodsThe pertinent literatures about pancreatic pseudocyst treated by endoscopic technique were summarized. ResultsEndoscopic technique possessed the peculiarities of less trauma, convenience to operate and could be repeatedly used. The number of patients with pancreatic pseudocyst suitable for endoscopic therapy was increasing. When pancreatic pseudocyst was accompanied with complication, polycystic or failed in endoscopic treatment, surgical intervention was the only choice. Endoscopic technique would be considered firstly in other conditions.ConclusionIndividual scheme should be advocated according to the size, number location and complication of the pancreatic pseudocyst.
Objective To compare vein graft patency after endoscopic great saphenous vein harvesting (EVH) and conventional open saphenous veinharvesting (OVH) in coronary artery bypass grafting (CABG), and to identify risk factors for vein graft stenosis. Methods The great saphenous vein was harvested using an EVH method in 60 patients, 34 males and 26 females, who underwent CABG in the General Hospital of PLA between May 2006 and May 2009. The mean patient age was 66.6±9.2 years in the EVH group.The OVH group had 60 patients (40 males and 20 females with a mean age of 65.7±10.6 years), chosen to match the clinical characteristics of the EVH group. 64multislice computed tomography (64MSCT) was used to evaluate vein graft patency at six months and two years postoperatively. We also collected and analyzeddata on possible risk factors for vein graft stenosis. Results The harvesting time was longer in the EVH group than in the OVH group (52.5±13.3 minutes vs. 36.1±18.0 minutes, t=2.13, P＜0.05). The EVH group requireda greater number of repairs to veins than did the OVH group (2.2±13 vs. 0.9±0.6,t=2.60, P＜0.05). There were no statistically significant differences invein length, number of vein grafts, or vein graft flow between the two groups. There was also no significant difference in vein graft patency between the EVH and OVH groups at six months postoperatively (96.2% vs. 94.5%) or at two years postoperatively (90.2% vs. 91.5%). The average of vein graft blood flow was a riskfactor for vein graft stenosis(t=2.61, P=001). Conclusion The EVH vein graft had a good patency rate at six months and two years after the surgery.
