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.     

腹腔镜胆囊切除术患者围术期多项血清应激状态相关指标变化观察

目的:分析腹腔镜胆囊切除术的临床疗效,分析其对血清应激指标的影响。方法:将160例来我院行胆囊切除术的患者随机分为两组,对照组和观察组各80例。对照组采用开腹胆囊切除术,观察组则采用腹腔镜胆囊切除术。比较两组间手术时间、术中出血量、肠功能恢复时间以及住院天数差异,比较治疗前后两组患者间血清应激相关指标皮质醇(COR)、去甲肾上腺素(NE)、促肾上腺皮质激素(ACTH)、多巴胺(DA)以及胰岛素(INS)、三碘甲状腺原氨酸(T3)、甲状腺素(T4)、促甲状腺激素释放激素(TSH)水平差异。结果:观察组患者手术时间、术中出血量、肠功能恢复时间以及住院天数均显著少于对照组(P<0.05)。血清COR、NE、ACTH、DA和INS、T3水平在围手术期均发生了显著变化,各项指标均在胆囊分离时就明显升高,术后24 h开始下降(P<0.05);术后观察组上述指标均显著低于对照组(P<0.05)。结论:腹腔镜胆囊切除术对机体应激反应影响小于开腹手术,更利于患者术后康复。

保留足趾的自体复合第2足趾关节移植治疗手指关节炎

目的 探讨保留足趾的自体复合第2足趾关节移植治疗手指关节炎的临床疗效.方法 2016年2月至2018年6月,共收治创伤性手指关节炎9例,其中男7例,女2例;年龄19~53岁,平均31.7岁;示指3例,中指6例;掌指关节(MP)关节炎4例,近侧指骨间关节(PIP)关节炎5例;均为创伤后继发的手指关节炎.采用游离带血供的自体复合第2足趾跖趾或趾骨间关节移植进行治疗,同时将受区废弃关节(7例)或切取自体髂骨移植(2例)修复供区骨缺损保留足趾长度,供区创面均直接关闭.术后观察手指和足趾骨折愈合情况、外形、移植关节活动度(ROM)、术后供区愈合情况和行走功能及相关并发症.结果 本组术后9例移植关节全部成活,1例足部供区行髂骨植骨微型钢板固定,术后1周伤口不愈合,考虑为内固定物排异反应,予拆除钢板改克氏针交叉固定,2周后创口顺利愈合.术后随访6~30个月,平均16.3个月.手指骨折平均愈合时间7~10周,平均8.3周,手指外观及功能良好.移植后的MP活动度为50°~75°,平均65.3°,PIP活动度为10°~85°,平均60.6°.根据中华医学会手外科学分会上肢部分功能评定试用标准评价手指功能:优5例,良3例,可1例,优良率为88.9%.足趾骨折平均愈合时间9~12周,平均10.2周,所有患者足趾外形良好,行走功能正常.2例取髂骨患者供区仅残留一条线形瘢痕,无疼痛、麻木等不适.结论 游离带血供的自体复合第2足趾关节移植治疗手指关节炎,同时应用受区废弃关节或切取自体髂骨移植修复供区骨缺损保留足趾,不仅能恢复手指关节的正常结构,使关节具有良好的功能,而且能保留足趾外形与功能,减少供区损伤,具有良好的治疗效果.     

500 Cases of High-intensity Focused Ultrasound (HIFU) Ablated Uterine Fibroids and Adenomyosis

ObjectiveClinical outcomes of 500 high-intensity focused ultrasound (HIFU)-treated uterine fibroids and adenomyosis are analyzed and presented.Materials and methodsThis is a retrospective cross-sectional analysis from a single tertiary medical center. From April 2015 to October 2018, 546 cases were enrolled for the study. After excluding 46 patients with less than 3 months of follow-up period, there were 404 fibroids, 149 adenomyosis and 53 mixed conditions entered for analysis. The patients’ uterine fibroids and adenomyosis were treated by HIFU according to Chongqing Haifu protocol, with 12 cm diameter transducer of focal length 10–16  cm at 0.8 or 1.6 MHz T2-weight MRI imaging was rendered prior to and 3 month post treatment to assess lesion volume change using non-perfusion volume, which was the primary outcome. Secondary outcomes including quality of life, subjective satisfaction, adverse events and pregnancy rate were determined using self-reported questionnaires. The mean follow up period ranged from 3 to 38 months with an average of 21 months.ResultsThree months after HIFU-treated uterine fibroids and adenomyosis, the lesion size reduced 40.2% and 46.3%, respectively. Symptoms all improved with better quality of life for the fibroid group, while those with adenomyosis or combined diseases benefit the most from pain control. Serum CA125 decreased significantly for all studied groups, and LDH only showed improvement for fibroids group. Number of adverse events is comparable to Chongqing data (approximately 10.2%), with mostly mild and self-resolving conditions. No permanent sequelae or death was documented. Twelve pregnancies are reported in this cohort.ConclusionHIFU is safe and effective in treating uterine fibroids and adenomyosis. The results are reproducible if standardized treatment schedules are followed. It is a promising treatment alternative with the advantages of precision, non-invasiveness, rapid recovery and readiness for pregnancy.     

腹腔镜"蘑菇状"剜除术治疗外生性肾血管平滑肌脂肪瘤的临床应用

目的对比研究腹腔镜下外生性肾血管平滑肌脂肪瘤"蘑菇状"剜除与标准肾部分切除术的安全性及有效性，为肾血管平滑肌脂肪瘤腹腔镜下"蘑菇状"剜除术术式的建立提供临床依据。 方法选取海南医学院第二附属医院与解放军总医院2018年1月至2019年5月期间，接受腹腔镜手术的肾血管平滑肌脂肪瘤患者53例，其中25例沿肿瘤假包膜行"蘑菇状"剜除术(A组)、28例行肾部分切除术(B组)。比较两组手术患者的肾动脉阻断时间、手术时间、术中出血量、术后24 h血红蛋白、术后eGFR(estimated glomerular filtration rate,估计肾小球率过滤)的变化、术后住院时间和术后肿瘤复发率。 结果53例手术无术中转开放，无死亡病例。肾动脉阻断时间：A组(11.9±2.2)min、B组(21.5±6.5) min(P<0.001)。手术时间：A组(87.9±24.8)min、B组(114.3±38.9) min(P<0.001)。术中出血量：A组20 ml(20～40)ml、B组50 ml(50～100)ml(P<0.001)。术后24 h血红蛋白变化：A组(7.4±4.3) g/L、B组(12.4±8.8) g/L(P＝0.013)。术后24 h eGFR变化：A组(6.2±7.2 )ml(min·1.73 m²)，B组(12.7±12.8)ml(min·1.73 m²)(P＝0.027)。术后6个月eGFR变化：A组(1.5±3.7)ml(min·1.73 m²)、B组(6.5±5.6)ml(min·1.73 m²)(P<0.001)。术后住院时间：A组4.0 d(3～4)d、B组4.5 d(3～6)d(P＝0.023)。术后随访两组术后肿瘤均无复发。 结论采用腹腔镜"蘑菇状"剜除术治疗外生性肾血管平滑肌脂肪瘤在肾动脉阻断时间、术中出血量、术后24 h血红蛋白、术后eGFR变化、术后住院时间等方面均优于传统肾部分切除术，两组术后肿瘤均无复发；该方法安全、有效，适于临床推广。
