To determine the incidence of incisional hernia (IH) in the extraction incision (EI) in colorectal resection for cancer. To analyze whether the location of the incision has any relationship with the incidence of hernias and whether mesh could be useful for prevention in high-risk patients.

不同手术方法治疗复杂胫骨平台骨折临床疗效观察

目的探讨不同手术方法治疗复杂胫骨平台骨折临床疗效。方法选择2016年1月—2018年12月84例复杂胫骨平台骨折患者,随机分组。单侧锁定钢板内固定组选择单侧锁定钢板内固定手术,双侧切口双侧解剖钢板内固定组选择双侧切口双侧解剖钢板内固定。分析手术操作时间、手术失血、平均住院天数以及复杂胫骨平台骨折愈合时间;治疗前后患者视觉模拟评分和Rasmussen膝关节功能评分;膝关节僵硬发生率。结果双侧切口双侧解剖钢板内固定组视觉模拟评分和Rasmussen膝关节功能评分、手术操作时间、手术失血、平均住院天数以及复杂胫骨平台骨折愈合时间、膝关节僵硬发生率和单侧锁定钢板内固定组比较有优势,P<0.05。结论复杂胫骨平台骨折患者实施双侧切口双侧解剖钢板内固定可获得较好效果。     

Tumor-to-tumor metastases: Latent renal cell carcinoma discovered after elective surgical resection of a convexity meningioma

BackgroundTumor-to-tumor metastases are extremely rarely reported lesions, which usually involve an indolent lesion hosting a more aggressive neoplasm. We present an unusual initial manifestation of a previously unknown clear cell renal cell carcinoma as a tumor-to-tumor metastasis in a typical meningothelial meningioma.Case reportA 73-year old patient with transient left slight monoparesis was addressed to our Neurosurgical Department after being evaluated by his general practitioner and passing a cerebral MRI which revealed a right frontotemporal mass attached to the meninge. At presentation, no deficits were identified; therefore an elective surgery was proposed. Histological analysis revealed a typical meningothelial meningioma containing a metastatic clear cell renal cell carcinoma. Additional thoraco-abdominal computer tomography identified a 6 cm diameter lesion within the right kidney with radiological features highly suggestive of a primary clear cell renal cell carcinoma.ConclusionOur case highlights the need for a specialized neuropathological approach to clinical and imagistic indolent meningiomas, as they may require important differential diagnosis that can highly impact the treatment and follow-up of brain tumor patients.     

两例 SMILE 术中特殊情况更改 SBK 手术的疗效观察

目的：通过对同一患者双眼不同手术方式的自身对比，了解飞秒扫描后改SBK手术的疗效差异，为不同患者屈光手术方式的选择提供临床指导依据。方法回顾分析2例右眼行飞秒激光小切口透镜取出术（ SMILE），左眼SMILE术中负压环脱失和激光扫描不良透镜分离困难而改行机械刀制瓣准分子激光手术（ SBK）的患者，比较术后视力、等效球镜（ SE）、对比敏感度（ CSF）、波前像差（ HAOS）以及泪膜破裂时间（ BUT）、泪液分泌功能试验（ Schimer I）和SPEED、OSDI干眼症状问卷调查分析差异。结果（1）术后个月，均能达到最佳矫正视力（BSCVA），等效球镜均在±0．75 D以内，双眼比较无显著性差异。（2）CSF的比较，左右眼无显著性差异，略低于正常水平。（3）术后3个月，BUT和Schimer检查中，双眼无显著性差异。（4）HAOS比较中，总像差RMS和高阶像差这两项， SMILE眼低于SBK眼；球差（S）的比较，SMILE眼高于SBK眼。（5）SPEED和OSDI问卷评分双眼无显著差异。结论 SMILE失败眼改SBK后视觉质量与SMILE眼无显著差异，其视觉质量、疗效不受影响。     

Adult Renal Cell Carcinoma: A Review of Established Entities from Morphology to Molecular Genetics

According to the current World Health Organization (WHO), renal cell carcinomas (RCCs) that primarily affect adults are classified into 8 major subtypes. Additional emerging entities in renal neoplasia have also been recently recognized and these are discussed in further detail by Mehra et al (Emerging Entities in Renal Neoplasia, Surgical Pathology Clinics, 2015, Volume 8, Issue 4). In most cases, the diagnosis of a RCC subtype can be based on morphologic criteria, but in some circumstances the use of ancillary studies can aid in the diagnosis. This review discusses the morphologic, genetic, and molecular findings in RCCs previously recognized by the WHO, and provides clues to distinction from each other and some of the newer subtypes of RCC. As prognosis and therapeutic options vary for the different subtypes of RCC, accurate pathologic distinction is critical for patient care.     

结膜入路整形术治疗下眼袋

自１９９３年以来，对５２岁以下较为严重下眼袋患者施术２２例，共计４４只眼，应用结膜入路下眼袋整形术，这一手术方法既克服了皮肤入路手术皮肤遗留痕迹的缺点，且有手术过程操作简单，出血少，不损伤重要组织及血管等特点，满意率达９７．７３％，取得了满意的临床效果。作者阐述了手术适应证、手术设计、方法以及注意事项，同时认为严格手术适应证和精湛外科技术是手术成功的关键。     

下腹部Joel—Cohen切口术后切口愈合临床观察

目的探讨肥胖患者下腹部手术采用Joel—Cohen切口对预防非感染性切口裂开的临床效果。方法选择切口部位皮下脂肪层厚达4—5cm的妇产科手术患者90例，随机分为观察组44例，采用Joel—Cohen切口；对照组46例，采用下腹正中直切口。观察切口愈合和脂肪液化情况。结果观察组切口甲级愈合率显著高于对照组（P〈0．01）；脂肪液化切口裂开率显著低于对照组（P〈0．05）。结论脂肪组织厚达4—5cm以上下腹部手术切口，采用Joel—Cohen切口可以减少脂肪液化，切口愈合显著优于下腹直切口，值得临床推广应用。     

经颞部骨膜下剥离面中部提紧术

目的探讨一种经颞部矫正面中部老化征象的简单而有效的方法。方法经颞部头皮切口在颞浅筋膜和颞深筋膜间剥离,下达颧弓,内达眶外侧缘。在颧弓上约2cm,平行颧弓切开颞深筋膜浅层约3cm,在颞深筋膜浅层下剥离至颧弓上缘进入骨膜下剥离。松解面中部。将已充分活动的面中部全层组织上提,缝合固定于颞深筋膜表面。结果自2000年以来,临床应用21例,术后效果满意,外观自然,无并发症发生。结论本方法具有手术时间短,剥离层次深,耳前无切口,术后恢复快,效果自然,维持时间长的优点。选择合适的病例,能获得满意的效果。
