Perianal Paget’s disease: case report and review of the literature

A peri-anal skin lesion, often eczema-like and with symptoms of pruritus, that does not resolve after classical local therapy should be biopsied. We present a case of peri-anal extramammary Paget’s disease (EMDP) and associated anal adenocarcinoma. Reviewing the literature, more than 30% of patients with EMDP present a second primary tumour in their past, present or future history. In Europe, the risk of developing a new primary tumour in patients with this condition is increased compared with the standard population. In cases of peri-anal Paget’s disease (PPD), specific histochemical markers allow us to differentiate between a primary and a secondary form, the secondary one is strongly associated with colorectal and anal tumours. We provide information about the most commonly suggested therapy for PPD with or without associated malignancy and about the recommended follow-up.     

等离子射频辅助双侧声带后端切断术治疗双侧声带麻痹导致的上气道梗阻患者13例

目的 评估内镜下等离子射频辅助双侧声带后端切断术治疗双侧声带麻痹导致上气道梗阻患者的疗效。 方法 回顾性分析13例双侧声带麻痹导致的上气道梗阻患者的病例资料,其中男6例、女7例,27~73岁,所有患者均接受等离子射频辅助双侧声带后端切断术。总结评估该手术的临床疗效。 结果 13例随访时间1年1个月~2年11个月,所有患者无严重并发症发生。一次拔管率为84.44%(10/13),二次手术拔管率为88.89%(11/13),拔管时间1~3个月,中位数1个月,上气道梗阻均未复发。 结论 内镜下等离子射频辅助双侧声带切断术操作简单、手术风险小,同时治疗双侧声带麻痹效果可靠,是双侧声带麻痹导致上气道梗阻的有效治疗方法之一,也可作为其他治疗失败的补救治疗措施。     

高频超声对女性肛门括约肌完整性评估的可行性研究

目的 利用高频超声对女性肛门括约肌进行显像与评价,验证高频超声运用于女性肛门括约肌完整性评估的可行性。方法 2020年1月-2021年3月期间行盆底超声检查的110例女性受检者,通过高频线阵探头分别从横断面及矢状面对其肛门括约肌进行连续性扫查,而后两位经验不同的研究人员在互盲情况下独立对肛门括约肌的影像进行完整性评价,记录肛门括约肌损伤情况并进行统计分析。结果 在全部受检者中,高频超声均可从横断面及矢状面清晰地显示各水平肛管特征性的解剖结构,从而当出现异常的超声表现时,可以实现对肛门括约肌损伤的检出。通过Kappa一致性检验可得高频超声对肛门括约肌的完整性评价在不同经验的研究人员间也具有较强的一致性(Kappa=0.888,P<0.05)。结论 高频超声通过对各水平肛管的清晰成像,可以实现对肛门括约肌的完整性评价,为肛门括约肌的评估提供一种新的影像学手段。     

瘘管切除合并内口结扎治疗肛瘘临床疗效分析(附74例报告)

目的观察瘘管切除合并内口结扎治疗肛瘘的临床疗效。方法选择74例内口在肛管齿线附近的肛瘘患者,采用将瘘管完全剥离切除,内口盲端结扎的方法手术的临床资料作回顾性分析。结果 74例患者全部一次性治愈,住院时间为12~23d,完全愈合时间为22~47d。痊愈后肛门外观无缺损、移位等改变,生理功能正常。3例患者早期有少许黏液泄漏,8~10周后症状消失,肛门无失禁。结论采用瘘管切除合并内口结扎的手术方法治疗肛瘘彻底,治愈率高,疗效确切,无肛瘘再次复发。     

磁共振成像（MRI）评价肛瘘与手术的相关性

目的：探讨磁共振成像（MRI）评价肛瘘与手术的相关性,为临床诊断提供参考。方法：选取2012年2月-2014年5月本院疑似肛瘘的58例患者为研究对象,平均年龄（43.35±12.21）岁。所有患者均采用PHILIPS Achieva 1.5 T超导型磁共振扫描仪扫描进行MRI检查,相控阵列线圈,层厚4 mm,无间隔,分别作横轴位、横截面及矢状面扫描,记录扫描所得数据。结果：MRI能够正确识别内口56例,脓腔54例,主管55例,支管51例。T2-weighted快速自旋回波脂肪饱和图像和增强后的T1-weighted快速自旋回波脂肪饱和图像进行对比检测支管和内口情况,除3例患者的支管出现在T1-weighted image TSE TRA FS却在T2-weighted image TSE TRA FS上消失,这两个序列检查支管的准确方面比较差异无统计学意义（X^2=1.037,P=0.387）。除7例患者的内口出现在T2-weighted image TSE TRA FS却在T1-weighted image TSE TRA FS上消失,这两个序列检查内口的准确方面比较差异有统计学意义（X^2=5.02,P=0.04）。结论：T2-weighted image TSE TRA FS在检查内口方面效果更佳,MRI检查可以为临床提供准确的术前信息,是一种无创、准确、可靠的肛瘘检查方法,具有重要的临床实用和推广价值。     

Anal cancer – What is the optimum chemoradiotherapy?

Radical concurrent chemoradiotherapy with 5FU and Mitomycin C is the standard-of-care for squamous-cell carcinoma of the anus (SCCA). Phase III trials combined radiation doses of 50–60 Gy with concurrent Fluoropyrimidines, Mitomycin C and Cisplatin in various doses and schedules. CRT is highly successful for early T1/T2 cancers, but results in appreciable late morbidities and still fails to control larger and node-positive tumours.Compliance to chemotherapy is important for local control. Modern radiotherapy techniques such as intensity-modulated radiotherapy (IMRT), rotational IMRT, image-guided radiotherapy (IGRT) have enabled smaller margins and highly conformal plans, resulting in decreased radiation doses to the organs at risk and ensuring a shorter overall treatment time. These advances offer the potential for integrating higher doses of radiation, escalation of the currently used drugs and the safe use of other more novel agents with acceptable toxicity. In this chapter potential novel approaches are discussed in the context of SCCA.
