Intraoperative three-dimensional navigation for surgical treatment of osteoid osteoma in the foot and ankle – A series of 14 cases

BackgroundThe surgical treatment for osteoid osteoma (OO) in the foot and ankle is challenging. It is difficult to locate the lesion and the anatomy is crowded by sensitive structures. The purpose of this study was to describe the outcomes of navigated mini open-intralesional curettage (NMIC) or navigated minimally invasive radiofrequency ablation (NMRFA) in treating these lesions.MethodsAll patients who underwent surgery for OO in the foot and ankle between 2015 and 2020 were included. O-arm navigation was used in All procedures. The choice of NMIC versus NMRFA was made by the surgeon according to the location of the lesion and its proximity to sensitive anatomic structures.ResultsFourteen patients were included. Ten were operated by NMRFA and 4 by NMIC. All patients’ symptoms related to OO resolved following a single procedure. Average AOFAS score increased by 18.7 (P < .001). Three patients had the following complications: pathologic fracture, superficial infection and transient deep peroneal nerve sensory loss.ConclusionNavigated surgical treatment of OO in the foot and ankle is accurate, efficient and safe.     

腹腔镜下子宫双侧动脉阻断术联合清宫术治疗剖宫产瘢痕妊娠疗效分析

宫腔镜辅助下分段诊刮术与单纯分段诊刮术诊断子宫内膜癌的比较

为比较宫腔镜辅助下分段诊刮术与单纯分段诊刮术在诊断子宫内膜癌中的临床意义 ,将经手术后病理证实的子宫内膜癌患者分为 2组 :宫腔镜辅助下分段诊刮组 (A组 ) 3 1例 ;单纯分段诊刮组 (B组 ) 3 9例。比较 2组术前诊断子宫内膜癌的准确性及开腹手术时腹水细胞学的检查结果。 2组患者的年龄、临床病理分期、病理分级及组织学类型差异无显著性。A组诊断宫颈受累的准确率为 96.77% (3 0 / 3 1 ) ,假阳性率为 3 .2 3 % (1 / 3 1 ) ;B组分别为 79.49%(3 1 / 3 9) ,1 5 .3 8% (6/ 3 9)。 2组准确率比较 ,差异有显著性 (P <0 .0 5 )。取腹水或腹腔冲洗液行细胞学检查。A组细胞学阳性率为 6.45 % (2 / 3 1 ) ,B组为 1 4.2 9% (3 / 2 1 ) ,2组间差异无显著性 (P >0 .0 5 )。提示 :宫腔镜辅助下分段诊刮术可提高术前诊断子宫内膜癌的准确性 ,从而避免不必要地扩大手术范围 ,而且不增加腹腔内播散的危险。     

晚期产后出血问题的探讨(附52例临床分析)

本文对52例晚期产后出血病例进行了分析,结果认为晚期产后出血与感染密切有关;在处理上诊断性刮宫仍是重要措施之一,并提出对存在感染因素的产妇,术前、产前应用抗菌素预防感染.在剖宫产过程中,可用含抗生素的溶液冲洗宫腔,以达到预防感染的目的。

The relationship of placenta previa and history of induced abortion.

OBJECTIVES: We evaluated the risk of placenta previa being associated with a history of induced abortion by different surgical procedures. METHODS: Cases (n=192) were women who had a singleton delivery complicated by placenta previa at a major obstetric care hospital in western Washington state between April 1, 1990 and December 31, 1992. Controls (n=622) were women with singleton deliveries not complicated by placenta previa or abruption. Odds ratios, determined by logistic regression, approximate the relative risks. RESULTS: Vacuum aspiration abortion was not associated with an increased risk of placenta previa (OR 0.9, 95% CI 0.6-1.5). However, the risk of placenta previa increased with the number of sharp curettage abortions (OR 2.9, 95% CI 1.0-8.5 for > or =3). CONCLUSIONS: Risk of placenta previa may be increased in a dose response fashion by multiple sharp curettage abortions. However, vacuum aspiration does not confer an increased risk, and may be a better alternative.     

子宫内膜癌42例临床分析

目的了解子宫内膜癌发病的高危因素，探讨其早期诊断的手段。方法对42例子宫内膜癌的病史、临床表现、诊断技术及病理类型进行分析。结果子宫内膜癌占同期生殖系统恶性肿瘤病人的38．1％，不规则子宫出血是子宫内膜癌的主要症状，其次是阴道排液增多。不孕病人及更年期功能性子宫出血长期受无孕激素桔抗的雌激素刺激是本病的高危因素。结论诊断性刮宫及超声波探查对诊断及分期是必不可少的方法。
