老年人桡骨远端C型骨折的手术治疗与非手术治疗的疗效对比

目的：探讨老年人桡骨远端C型骨折的手术治疗与非手术治疗的疗效差异，评价两种方法的优缺点。方法回顾性分析2009-12—2011-12收治的老年桡骨远端C型骨折68例，按照治疗方法分为A组(手术组)及B组(非手术组)，统计分析两组患者的临床资料。结果 A组33例， B组35例，平均随访21.5个月。两组患者的年龄、骨折类型均无差异(P＞0.05)；术后影像学指标A组优于B组，骨折愈合时间B组优于A组，治疗成本A组大于B组(P＜0.05)；Cooney评分早期A组优于B组，1年后两组无差异，两组的并发症无差异(P＞0.05)。结论老年人桡骨远端C型骨折手术治疗较非手术治疗可获得更好的复位及早期功能，但远期功能恢复无差异。     

Distal biceps rupture: Evaluation and management

Injury to the distal biceps occurs in certain high risk groups. Anatomical continuity of the lacertus fibrosus has bearing on the extent of retraction of the torn tendon stump. The objective of clinical and imaging evaluation is to discriminate between tendinosis, partial tear, acute complete tear and chronic complete tear. A complete tear of the distal biceps tendon can be diagnosed clinically with the Hook test. The traditional Hook test and the resisted Hook test are useful clinical tests. Though x-rays are routinely done, MRI remains the investigation of choice. Non-operative treatment has a role in selected patients with partial tear or patients with complete tear who have low functional demands. Operative treatment is the recommended treatment for complete tear of the distal biceps and is associated with good functional outcome and patient satisfaction.     

Short- to medium-term results of single-anastomosis duodeno-ileal bypass compared with one-anastomosis gastric bypass for weight recidivism after laparoscopic sleeve gastrectomy

BackgroundSingle-anastomosis duodeno-ileal bypass (SADI) and the one-anastomosis gastric bypass (OAGB) are 2 revisional procedures to address the problem of weight recidivism after laparoscopic sleeve gastrectomy (LSG).ObjectivesTo evaluate the efficacy and safety of SADI and OAGB as revisional bariatric surgery (RBS) in initially super-obese patients (body mass index [BMI] >50 kg/m²).SettingAcademic hospital, bariatric center of excellence, Germany.MethodsObservational study of outcomes in 84 initially super-obese patients who had undergone RBS after LSG (SADI n = 42, OAGB n = 42) between July 2013 and April 2018. Follow-up examinations were performed at 1, 6, 12, 24, and 36 months after RBS. The variables analyzed included time between LSG and RBS, BMI, excess weight loss, total weight loss, operation time, and complications.ResultsThe time interval between LSG and RBS was 45.5 ± 22.8 and 43.5 ± 24.2 months for SADI and OAGB, respectively. At the time of RBS, the mean BMI was 42.8 ± 7.9 kg/m² for SADI and 43.4 ± 9.2 kg/m² for OAGB. The follow-up examinations rates (%) after SADI were 97.6, 92.8, 90.5, 78.6, 57.1, and 100, 97.6, 95.2, 85.7, and 59.5 after OAGB. The BMI at the follow-up examinations were 39.1 ± 7.2, 34.2 ± 6.9, 31.2 ± 5.8, 30.2 ± 5.3, 29.3 ± 5.1 for SADI, and 39.5 ± 8.1, 36.6 ± 7.4, 34.7 ± 7.9, 32.9 ± 6.3, and 31.6 ± 5.9 for OAGB. The mean operating times for SADI and OAGB were 138 ± 40 and 123 ± 39 minutes, respectively. Three patients in the SADI group and 1 patient in the OAGB group developed a major complication within the first 30 postoperative days.ConclusionSADI and OAGB were effective second-step procedures for further weight reduction after LSG in initially super-obese patients after short to medium follow-up. There was a trend toward higher weight loss for SADI though this did not reach statistical significance. Substantial differences concerning surgery time and complications between the 2 procedures were not observed.     

经关节入路微创钢板固定技术治疗股骨远端C型骨折

目的探讨经关节入路微创钢板固定(MIPPO)技术治疗股骨远端C型骨折的临床疗效。方法2002年4月～2005年2月,应用MIPPO技术治疗股骨远端C型骨折14例,按AO/ASIF分类：C1型3例,C2型6例,C3型5例。先行关节内骨折切开复位、松质骨螺钉固定,再行髁上部分骨折间接复位、经关节内切口插入髁支撑钢板或LISS钢板桥接固定骨折。结果12例患者获得10～32个月(平均18．4个月)随访,骨折均获愈合,愈合时间10周～12个月,平均4．6个月。按Kolmert和Wulff的评价标准：优4例,良5例,可2例,差1例,优良率为75%。结论应用MIPPO技术治疗股骨远端C型骨折实现了微创操作,具有创伤小、软组织干扰少、骨折愈合快等优点,疗效满意。     

进展期胃癌的淋巴结转移特点及其临床意义

目的探讨进展期胃癌的淋巴结转移特点及临床意义。方法对2002年4月至2003年7月期间进行胃癌根治淋巴结清扫手术的91例患者的手术切除标本进行解剖，收集切除的淋巴结，逐枚进行病理组织学和免疫组织化学检查，判断淋巴结是否转移并计算淋巴结转移率。分析淋巴结转移率与肿瘤大小、TNM分期、Borrmann分型、肿瘤部位和淋巴结清扫范围等方面的关系。结果91例胃癌患者中淋巴结转移阳性63例（69．2％）。共收获3149枚淋巴结，平均每例34．6枚。肿瘤直径小于3cm者淋巴结转移率较3cm以上者低（P〈0．05）。TNM分期中Ⅲa和Ⅳ期患者淋巴结转移率均为100％，其转移度在30．3％～58．4％之间，较Ⅰ、Ⅱ期者高（P〈0．001）；Borrmann分型中Ⅲ型病例的淋巴结转移率（79．6％）较其他型患者高，而Ⅳ型患者淋巴结转移度（35．3％）最高（P〈0．05）。施行D3淋巴结清扫手术患者的淋巴结转移率和转移度（88．2％、38．0％）均高于D1、D2术患者（P〈0．05）。17例（18．7％）患者常规病理检查发现有183枚淋巴结微转移，肿瘤各部位与淋巴结微转移的关系差异无统计学意义（P〉0．05）。近端胃癌淋巴结转移主要在第1、2、3、5、7、8、9、12、13和16组，以8组转移度为最高（68．1％）；中部胃癌淋巴结转移主要在第1、3、7、12、13和16组，其中最高转移度为第3组（47．6％）；远侧胃癌淋巴结转移主要见于1、2．3、5、6、12、13和16组，其中第16组转移度为最高（83．3％）。结论淋巴结转移率和转移度与胃癌的恶性程度密切相关，因此D3淋巴结清扫手术对某些进展期胃癌患者值得考虑使用。     

Laparoscopic subtotal gastric resection for chronic gastric ulcers.

OBJECTIVES: We analyzed our experience with the laparoscopic approach for treating benign gastric lesions. METHODS: Between June 1998 and June 2002, we performed 18 gastric resections with the laparoscopic approach for 7 pyloric stenoses, 8 recurrent duodenal ulcers, and 3 chronic gastric ulcers. RESULTS: In our series, we performed Billroth II laparoscopic distal gastrectomy with no morbidity and mortality. CONCLUSIONS: Billroth II laparoscopic distal gastrectomy is safe in cases of benign gastric or duodenal lesions.
