肛瘘是因多种病理因素形成的肛管直肠与肛周皮肤相通的一种异常通道,手术是治疗肛瘘的主要手段。肛瘘的手术治疗既要保护肛门的功能,减少肛门括约肌的损伤,同时又要彻底清除内口,达到根治肛瘘的目的。因此,术前明确内口的位置和瘘管走行及其与周围肌肉组织的关系,对肛瘘手术方法的选择和保护肛门的生理功能具有重要意义[1]。随着现代影像学的进展,肛瘘X线造影、超声检查、CT、MRI等技术广泛应用于肛瘘的诊断,为手术提供了客观的影像学资料,对肛瘘的治疗具有重要价值。本文就肛瘘的影像学诊断现状作一综述。  相似文献

Objective This prospective study was designed to assess the accuracy of hydrogen peroxide‐enhanced ultrasound in the identification of internal openings of anal fistulas, with surgical findings as the golden standard. Patients and methods A total of 143 consecutive patients (102 men; mean age, 45 years) with fistula‐in‐ano were assessed by hydrogen peroxide‐enhanced ultrasound before surgery involving one radiologist. Ultrasound was performed using a B & K Diagnostic Ultrasound System? with a 10‐MHz rotating endoprobe. Hydrogen peroxide (3%) was infused into the fistula. All operations were perfomed by the same surgeon who was unaware of results of anal endosonography. Results In 128 (89.5%) patients, an internal opening was identified at surgery. Correct identification of an internal opening endosonographically was recorded in 80 (62.5%) patients. The internal opening was correctly identified by ultrasound in 32% (8/25) of patients with intersphincteric fistulas, in 77% (70/91) with transsphincteric fistulas, and in 17% (2/12) with suprasphincteric fistulas. Conclusion The accuracy of hydrogen peroxide‐enhanced anal endosonography for the identification of internal openings was still insufficient to justify pre‐operative endosonography as a diagnostic method for routine use in patients with fistula‐in‐ano.  相似文献

AIM: The purpose of the present study was to define the diagnostic value of anal endosonography in the diagnostic work-up of fistula-in-ano. METHODS: A retrospective study was carried out on 191 consecutive patients (m: 121; f: 70; mean age: 44.0 +/- 12.5 years; range: 0.5-77 years) who were diagnosed to suffer from fistula-in-ano by performing anal endosonography in an outpatient setting. All images were obtained with a Combison 310A ultrasound scanner (Kretz GmbH, Zipf, Osterreich) and 5-Mhz and 7.5-MHz transducer. 131 patients underwent surgery. According to the endosonographic findings fistulas were classified as transsphincteric in 44 %, intersphincteric in 22 %, subanodermal in 16 %, anovaginal in 8 %, suprasphincteric in 5 %, extrasphincteric in 1 % and others in 4 %. RESULTS: In 125 patients (95 %) the preoperative diagnosis was confirmed intraoperatively. This cohort included 12 patients with a complex fistula system. In only 6 patients the preoperative ultrasound finding was misinterpreted. CONCLUSION: In conclusion this study has shown that anal endosonography is a useful and reliable tool in the preoperative evaluation of uncomplicated and complicated anorectal fistulas.  相似文献

Background : Identification of the internal opening is an essential step in the management of fistula‐in‐ano. The predictive accuracy of Goodsall’s rule is compared with instillation of hydrogen peroxide for fistulas‐in‐ano. Methods : Thirty‐five patients (32 male, three female; median age 42 years; range: 6 months–70 years) were studied. Hydrogen peroxide solution was injected into the external opening of the fistula track and effervescence was observed at the internal opening within the anal canal. A fistula track was either excised or incised. Setons were placed within high fistulas. Results : There were 24 simple fistulas, compared to 11 complex fistulas (horseshoe, n = 4; abscess, n = 4). Eighteen external openings were anterior and 17 were posterior. Thirty‐four of 35 (97%) internal openings were identified. Only 20 internal openings were in accordance with Goodsall’s rule (positive predictive value: 59%). Predictive accuracy was greater for anterior external openings (13 of 18 (72%)) versus posterior external openings (six of 17 (41%); P = 0.016). For recurrent fistulas, seven of 17 fistula tracks had an internal opening in accordance with Goodsall’s rule, resulting in a positive predictive value of 41%. (Positive predictive value: anterior 67%vs posterior 12.5%; P = 0.0009.) Conclusion : The overall predictive accuracy of Goodsall’s rule was poor chiefly because of poor predictive accuracy in posterior and recurrent fistulas. The use of Goodsall’s rule alone in decision‐making before surgical intervention is not recommended.  相似文献

Pre-operative assessment of anal fistulas using endoanal ultrasound   总被引:1,自引:0,他引:1  
Objective To study the accuracy of endoanal ultrasound in pre‐operative assessment of cryptoglandular anal fistulas, with respect to the site of the internal opening, type and depth of the fistula tract. Patients and methods A consecutive series of 151 patients with anal sepsis underwent pre‐operative endoanal ultrasound assessment of a suspected anal fistula. Hydrogen peroxide was used to define the tract when there was doubt as to the course of the fistula. All patients subsequently had surgical exploration under anaesthesia, irrespective of findings at sonography. The site of the internal opening, depth and type of fistula were recorded at surgery, and concordance with the ultrasound was assessed. Results One hundred and forty‐five patients were subsequently shown to have a fistula at surgical exploration. Type of fistula: Two thirds were transsphincteric (63%) and one third were inter sphincteric (32%), with a few submucosal, and supra sphincteric fistulas. Ultrasound correctly predicted surgical findings in 82% of patients (124/151). Concordance was highest for transsphincteric fistulas (87%). Internal opening: Accuracy of predicting the site of the internal opening was 93% (140/151). The commonest site for the internal opening was the midline posteriorly (49%), followed by the midline anteriorly (25%), the rest lay laterally. Fistula depth: Ultrasound and surgical assessment of the depth of fistulas was concordant in 120 of 145 patients (83%). Conclusions Endoanal ultrasound has a high accuracy of predicting the site of internal opening of an anal fistula. Endoanal ultrasound is able to assess the type and depth of a fistula. This information is useful for pre‐operative planning of fistula treatment.  相似文献

The main purpose of a radiologist’s expertise in evaluation of anal fistula magnetic resonance imaging (MRI) is to benefit patients by decreasing the incontinence rate and increasing the healing rate. Any loss of vital information during the transfer of this data from the radiologist to the operating surgeon is unwarranted and is best prevented. In this regard, two methods are suggested. First, a short video to be attached with the standardized written report highlighting the vital parameters of the fistula. This would ensure minimum loss of information when it is conveyed from the radiologist to the operating surgeon. Second, inclusion of a new parameter, the amount of external sphincter involvement by the anal fistula. This parameter is usually not included in the MRI report. This can be evaluated as the height of penetration of the external anal sphincter (HOPE) by the fistula. The external anal sphincter plays a pivotal role in maintaining continence. This parameter (HOPE) is distinct from the ‘height of internal opening’ and assumes immense importance as its knowledge is paramount to prevent damage to the external anal sphincter by the surgeon during surgery.  相似文献

Purpose This prospective study was done to analyze the efficacy of commercial fibrin glue application in the healing of patients with fistulas-in-ano. Methods This clinical trial of 36 patients was performed during the period from November 2003 to May 2004. Thirty men and six women were treated for a fistula-in-ano with commercial fibrin glue application. None of the patients had undergone prior attempts to correct fistulas-in-ano surgically. All patients received preoperative mechanical bowel preparation and prophylactic intravenous antibiotics. In the operating room, the patients underwent an anorectal examination under spinal anesthesia. The external and internal fistula tract openings were then identified. The fistula tract was curetted. Fibrin glue was injected into the external fistula opening until fibrin glue could be seen coming from the internal opening. No dressing was applied over the external opening. Thereafter, the patient was discharged. A 1-week course of oral antibiotics was prescribed. The patients were followed up for 70 weeks with a mean of 54 weeks (range 40–70 weeks). Results The cause of the fistula-in-ano was cryptoglandular in all patients. The overall initial success rate was 77.8% (28/36). No complications were encountered related to the application. Two patients underwent a reapplication with fibrin glue and the fistulas of these patients were all closed. The overall success rate was 83.3% (30/36). Conclusion Fibrin glue application was thus found to be an easy, safe, effective, and useful alternative treatment in the management of fistulas-in-ano. However, our findings need substantiation by increasing the number of patients and prolonging the follow-up duration, as well as carrying out comparative studies.  相似文献

Background: Anal fistula plug was recently introduced as an alternative treatment for anal fistula. However, there is, so far, no published data on the use of the anal fistula plug both locally and in the Chinese population. Methods: From January 2007 to July 2008, consecutive Chinese patients with transphincteric or suprasphincteric anal fistula scheduled for elective surgery were enrolled. Anal fistula plug was used if examination under anaesthesia reviewed an internal opening. Baseline manometry pressure study was carried out for patients with recurrent fistulae. The operative technique was standardized. Measured outcomes included healing and recurrence rates, operating time, length of stay, and time for patients to return to work or normal activity. Results: Eleven patients underwent anal fistula plug placement, with a median follow up of 19 months. Five had completely healed fistulae, including three patients with recurrent fistulae. The success rate was 45 per cent. In the three patients with recurrent fistulae, no significant difference was demonstrated in the resting pressure between preoperative and postoperative values. There is an observable trend that proportionally more recurrent fistulae were healed by anal fistulae plug placement when compared to primary fistulae (100% vs 25%); the difference, however, did not reach statistical significance (P = 0.06, Fisher's exact test). At the conclusion of this study, no recurrence was noted in the five patients with confirmed healing. Conclusions: Our preliminary experience indicates anal fistula plug placement is safe and non-invasive. However, the efficacy appears lower than initially reported. Based on our data the routine use of an anal fistula plug cannot be recommended. In our opinion, anal fistula plug placement can be considered in patients with more complex, high fistulae and in those who have recurrent fistulae despite previous surgery. It provides a non-invasive alternative in these patients, in whom postoperative incontinence is a real concern.  相似文献

Aim Anography is a radiological investigation for fistula‐in‐ano that identifies the primary fistula track through the internal opening. The efficacy of anography as a radiological method of identifying the location of the internal opening was investigated. Method A retrospective study of 50 patients with a clinical diagnosis of fistula‐in‐ano of criptoglandular aetiology was performed. During anography, the location of the internal opening was recorded with respect to the quadrant of anal canal and distance from the anal verge. These data were compared with the findings during examination under anaesthesia (EUA), which was used as the gold standard for the identification of the internal opening. Results The sensitivity of anography for identifying a patent internal opening was 91% and specificity 100%. There was complete agreement between anography reports and findings at EUA regarding the quadrant of anal canal in which the internal opening was located. In more than 90% of patients, the internal opening was found at EUA within 1 cm from the site described on anography. Conclusion Anography is an accurate test for predicting the exact quadrant of the anal canal in which the internal opening is located, as well as the distance of the internal opening from the anal verge. This inexpensive and simple radiological investigation should be the test of first choice in the evaluation of patients with fistula‐in‐ano when difficulty is anticipated in identifying the internal opening.  相似文献
