Computational fluid dynamic comparison between patch-based and primary closure techniques after carotid endarterectomy

Objective

The aim of the study was to provide, by means of computational fluid dynamics, a comparative analysis after carotid endarterectomy (CEA) between patch graft (PG) and primary closure (PC) techniques performed in real carotid geometries to identify disturbed flow conditions potentially involved in the development of restenosis.

Grouping of body areas affected in traffic accidents. A cohort study

Background

Traffic accidents are considered a public health problem and, according to the World Health Organization, currently is the eighth cause of death in the world. Specifically, pedestrians, cyclists and motorcyclists contribute half of the fatalities. Adequate clinical management in accordance with aggregation patterns of the body areas involved, as well as the characteristics of the accident, will help to reduce mortality and disability in this population.

Reversal of idiopathic hypogonadotropic hypogonadism: a cohort study in Chinese patients

Although idiopathic hypogonadotropic hypogonadism (IHH) has traditionally been viewed as a life-long disease caused by a deficiency of gonadotropin-releasing hormone neurons, a portion of patients may gradually regain normal reproductive axis function during hormonal replacement therapy. The predictive factors for potential IHH reversal are largely unknown. The aim of our study was to investigate the incidence and clinical features of IHH male patients who had reversed reproductive axis function. In this retrospective cohort study, male IHH patients were classified into a reversal group (n = 18) and a nonreversal group (n = 336). Concentration of gonadotropins and testosterone, as well as testicle sizes and sperm counts, were determined. Of 354 IHH patients, 18 (5.1%) acquired normal reproductive function during treatment. The median age for reversal was 24 years old (range 21–34 years). Compared with the nonreversal group, the reversible group had higher basal luteinizing hormone (LH) (1.0 ± 0.7 IU l^-1 vs 0.4 ± 0.4 IU l⁻¹, P < 0.05) and stimulated LH (28.3 ± 22.6 IU l⁻¹ vs 1.9 ± 1.1 IU l⁻¹, P < 0.01) levels, as well as larger testicle size (5.1 ± 2.6 ml vs 1.5 ± 0.3 ml, P < 0.01), at the initial visit. In summary, larger testicle size and higher stimulated LH concentrations are favorite parameters for reversal. Our finding suggests that reversible patients may retain partially active reproductive axis function at initial diagnosis.     

南山医院妇科近10年腹腔镜手术严重并发症的回顾性分析

目的探讨妇科腹腔镜手术的并发症及处理措施。方法对我院2005年1月~2014年5月9208例妇科腹腔镜手术的临床资料进行回顾性分析。结果发生并发症9例,发生率0.1%(9/9208)。3例大血管破裂术中发现,间断缝合修补,术后生命体征平稳;肠管损伤1例,术后第5天发现,经阴道行直肠阴道瘘修补术;输尿管损伤3例,1例术中发现,即行输尿管移植术,其余2例术后1~2周发现,术后2个月余行开腹输尿管膀胱植入术;膀胱损伤2例,均为术中发现,腹腔镜下行膀胱修补术。9例术后3个月随访恢复好。结论术中应仔细解剖,手术结束前常规查看输尿管蠕动及膀胱情况,检查导尿袋尿是否红色及有无气体,怀疑肠道损伤可肛门直肠充气看盆腔有无水泡产生。大血管损伤应保持镇定,一般可以在腹腔镜下行缝合术。     

腹腔镜右半结肠癌根治术解剖学基础与规范化手术

腹腔镜手术现已广泛应用于结肠癌的手术治疗,其中的腹腔镜右半结肠癌根治术是难度较大的术式,术中需结扎处理的血管较多,且相关血管存在较多变异。完成规范化的腹腔镜右半结肠切除术,还需对淋巴结清扫范围及完整结肠系膜切除术有充分认识。本文结合国内外文献及我科腹腔镜右半结肠癌根治术的多年经验,对腹腔镜右半结肠癌根治术所需掌握的相关外科解剖做简要综述,探讨淋巴结清扫范围,并介绍我科规范化的腹腔镜右半结肠切除术操作流程供同道参考。
