目的观察中药坐浴联合太宁栓治疗慢性肛周湿疹的疗效。方法将83例慢性肛周湿疹患者随机分为治疗组和对照组,分别采用中药坐浴联合太宁栓和派瑞松软膏局部外搽联合太宁栓治疗;治疗2周,观察两组临床疗效和症状改善情况。结果治疗组总有效率为92.50%,对照组为88.37%;两组临床疗效比较有显著性差异(P〈0.05)。治疗后,两组瘙痒程度、皮疹面积、皮损形态积分较治疗前明显降低(P〈0.05),且治疗组低于对照组(P〈0.05)。治疗组复发率(5.00%)低于对照组(11.62%)(P〈0.05)。结论中药坐浴联合太宁栓可提高慢性肛周湿疹临床疗效。  相似文献

Introduction

Anal pain is defined as pain originating from the anal canal or the perianal area that can be attributed to a variety of medical problems. The current study's aim was to evaluate the role of combined endoanal, transperineal, and in married women, transvaginal ultrasound in clarifying the etiology of anal pain among our patient study group.

Methodology

A total of 180 patients presented to our radiology department complaining of anal pain and were examined using transperineal, endoanal, and in women, transvaginal ultrasound aided with three-dimensional capability. The final diagnosis was reached, according to the surgical results and the histopathology reports in cases diagnosed with anorectal neoplasms and perianal masses.

Results

A total of 100 patients were diagnosed with perianal fistulas. Twenty-five cases presented with anal abscesses. In four cases, pilonidal sinus extended to the perianal spaces. Three cases had hiradenitis suppurativa, 13 cases showed occult anal sphincter defects, two cases had anorectal neoplasms, and one case was diagnosed with soft tissue ependymoma overlying the coccyx. Three cases were diagnosed with perianal soft tissue masses. One case was detected with recto vaginal fistulas, 10 cases showed thick internal anal sphincter, two cases had perianal cysts, and one case had perianal hematoma. Two cases showed hemorrhage in Douglas' pouch, and one case had pelvic collection sequelae of perforated pelvic appendicitis. Three cases had pelvic endometriosis; one case was detected with missed contraceptive device in the rectum. Three cases were diagnosed with prostatitis and two cases with prostatic abscesses. Two cases had prostatic carcinoma and one case had prostatic sarcoma.

Conclusion

The combined approaches of endoanal, transperineal, and in women, transvaginal ultrasound aided with three-dimensional capability proved highly valuable in clarifying the etiology of anal pain in our study group.  相似文献

肛周脓肿的彩超诊断   总被引:1,自引:0,他引:1  
目的探讨经肛高频彩色超声波检查肛周脓肿的声像学特点及术前定位的应用价值。方法应用经肛高频彩色超声波检查肛周脓肿30例,并与常规专科检查结果相比较。作声像图描述及术前定位。结果经肛高频彩色超声波检查肛周脓肿声像图表现为低回声,无回声或混和回声区,病灶区域未测及明显血流信号。结论经肛高频彩色超声波用于肛周脓肿的诊断在显示病灶位置、形态、保存图像作对照研究等方面具有明显的优点,可为肛周脓肿的研究提供客观依据。  相似文献

A case of perianal Paget's disease associated with a cloacogenic carcinoma is presented. There was no clinical evidence of the Paget's disease, which was confined to a very small area. The points of particular interest were (1) the association of Paget's disease with a cloacogenic carcinoma, and (2) the dissimilarity between the pagetoid cells and the carcinoma cells. The histologic differences between the two cell types support the view that perianal Paget's disease and underlying carcinomas represent a multicentric reaction to an unknown stimulus  相似文献

MRI in Crohn's disease   总被引:9,自引:0,他引:9  
Technological developments have extended the role of MRI in the evaluation of the gastrointestinal tract. The potential of MRI to evaluate disease activity in Crohn's disease has been investigated extensively, as MRI has intrinsic advantages over other techniques, including noninvasiveness and the absence of ionizing radiation. For perianal fistulizing disease MRI has become a mainstay in evaluation of disease, as localization and extent of disease can be very well appreciated using both T2-weighted and T1-weighted sequences, fat suppression, and intravenous contrast medium. Imaging of the small bowel and colon in Crohn's disease is more complicated due to bowel peristalsis and respiratory movement. However, using fast breathhold sequences and intravenous spasmolytic medication, images of good diagnostic quality can be acquired. To obtain sufficiently distended bowel, which in our estimation is a prerequisite for evaluation of the bowel, MR enteroclysis can be performed. However, applicability of different oral contrast media has been studied, as a noninvasive method for bowel distension would be preferable. Abdominal MRI is a valuable imaging technique for evaluation of luminal, transmural, and extraintestinal manifestations of Crohn's disease as degree of disease activity, presence of luminal pathology (e.g., stenoses), and extraintestinal manifestations of disease (e.g., abscesses, fistulas) can be accurately assessed.  相似文献

ABSTRACT:  Infants and children have special issues with regard to genital disease. Infants are incontinent, and have an increase in local irritation and infection risk. In addition, the adult sex hormones which enhance the health of genital skin are deficient. Also, the choice of therapy must be modified to take into account the more fragile nature of prepubertal skin, the tolerance of children to painful treatments, and the lack of experience of some medications in children.  相似文献
