Outcomes Following Intrasphincteric Injection of Botulinum Toxin for Treatment of Anal Fissures.

Background Intrasphincteric injection of botulinum toxin is an alternative treatment for anal fissures, which may present less risk of fecal incontinence than more invasive procedures, such as lateral internal sphincterotomy. The aim is to compare cure and complication rates between these two treatments. Methods We conducted a retrospective audit of patients who underwent treatment of anal fissures with intrasphincteric botulinum toxin or lateral internal sphincterotomy from 2016 to 2020 at the Colorectal Surgery Unit of Monash Health, Melbourne, Australia, excluding those who had previously had either procedure. Results Fifty-one patients received intrasphincteric botulinum toxin, and 40 patients underwent lateral internal sphincterotomy. Most patients in the botulinum group had a total dose of either 80 (53%; n=27) or 100 units (37%; n=19) and had the dose administered bilaterally at the 3 o'clock and 9 o'clock positions (n=41; 80%). Thirty-one patients in the botulinum group (61%) had complete resolution of symptoms, with a mean time to cure of two months, compared to 36 patients (90%) in the sphincterotomy group with a mean time to cure of 1.5 months. In most cases, postoperative incontinence was transient, although one patient in the botulinum group had persistent incontinence of flatus, and two patients in the sphincterotomy group had persistent fecal incontinence. Conclusion Intrasphincteric botulinum injection is an effective, less-invasive alternative to sphincterotomy for the treatment of anal fissures, with incontinence usually temporary when it occurs. Further research is needed to optimize the dose and location of injection and guide future recommendations.

[Current guidelines for the management of anogenital diseases]. / Aktuelle Leitlinien zur Diagnostik und Therapie von Erkrankungen im Anogenitalbereich.

BACKGROUND: Anogenital disorders encompass a broad spectrum of conditions with diverse pathogenetic origins, often presenting with nonspecific symptoms and overlapping causative factors, thereby posing diagnostic and therapeutic challenges. Effective management requires interdisciplinary knowledge and the use of medical guidelines. Guidelines can play an important role in translating current knowledge into clinical practice and ensuring consistent care, minimizing complications, and optimizing patient outcomes. OBJECTIVE: The dermatologically relevant guidelines for anogenital disorders, categorized by etiological groups, are reviewed. MATERIALS AND METHODS: A selective literature review was conducted, incorporating data from the guideline repository of the Association of the Scientific Medical Societies in Germany (AWMF). RESULTS: A broad range of current guidelines pertinent to the management of anogenital disorders with relevance for dermatologists is available. These encompass guidelines for the management of chronic inflammatory dermatoses with (potential) involvement of the anogenital region, such as anal eczema, psoriasis, lichen sclerosus, or lichen ruber, as well as sexually transmitted infections and associated conditions, involving a broad range of pathogens, including gonorrhea, chlamydia, syphilis, or human papillomaviruses (HPV)-associated disorders. In this article, we provide an overview of the available guidelines. CONCLUSION: The present article does not claim to be exhaustive. The validity of the mentioned guidelines and the availability of updates needs to be verified in each case.

Infantile perianal pyramidal protrusion: A retrospective review of 27 patients.

BACKGROUND: Infantile perianal pyramidal protrusion (IPPP) is a rare benign skin condition that is typically seen in infant girls. This condition is often mistaken for other skin lesions such as acrochordons, condyloma acuminatum, and sequelae of sexual abuse. Many clinicians are unfamiliar with IPPP which can lead to aggressive workup and treatment. The purpose of this study was to elucidate demographic data, clinical features, diagnostic workup, and management of IPPP in a large cohort of patients seen at an academic medical center. METHODS: A retrospective review of patients diagnosed with IPPP at Mayo Clinic, Rochester, MN was conducted. Demographic data, examination findings, diagnostic workup, and treatments were noted. RESULTS: Twenty-seven patients with IPPP, 24 of which were girls and 3 were boys from the ages of 1 day to 4 years (mean 10.8 months, median 8.6 months) were identified. Symptoms were reported in 63% (17/27) of patients. Four patients received treatment with topical corticosteroid or local anesthetic. No patient underwent skin biopsy. CONCLUSION: IPPP is commonly observed in healthy prepubertal girls. Constipation is a common symptom. Awareness of this entity may prevent overtreatment and unnecessary evaluation.

Impact of Sarcopenia on Clinical Course of Inflammatory Bowel Disease in Korea.

BACKGROUND AND AIMS: Reduced body muscle mass is a poor prognostic factor for inflammatory bowel disease (IBD). In this study, we investigated the prevalence of sarcopenia at diagnosis and its clinical significance in Korean patients with IBD. METHODS: The prevalence of sarcopenia in IBD patients between June 1989 and December 2016 was investigated using a well-characterized referral center-based cohort. Abdominopelvic computed tomography within six months from IBD diagnosis was used for the evaluation. Sarcopenia was defined as an L3 skeletal muscle index of < 49 cm2/m2 for male and < 31 cm2/m2 for female. The clinical characteristics and outcomes were evaluated with respect to sarcopenia. RESULTS: A total of 1,027 patients (854 Crohn's disease [CD]; 173 ulcerative colitis [UC]) were evaluated. Sarcopenia was found in 56.8% of the population (CD, 57.5%; UC, 53.2%), and male were more likely to be sarcopenic (CD, 94.3%; UC, 91.6%). There were no significant differences in the cumulative risk of using steroids, immunomodulators, biologics, and bowel resections (or colectomy) with or without sarcopenia during follow-up (median: CD, 5.8 years; UC, 3.7 years). In sarcopenic patients with CD, there was a significantly higher cumulative risk of perianal surgeries than in non-sarcopenic patients with CD (Log-rank test; P = 0.001). However, the risk of perianal surgeries was not significant in multivariate analysis (Odds ratio 1.368; 95% confidence interval 0.782-2.391; P = 0.272). CONCLUSION: Sarcopenia at diagnosis may have no significant prognostic value for medical treatment and bowel resection, but it may be associated with perianal CD.

Objective:To explore the effects of Compound Huangbai Liquid coating combined with Xiaochuang Mixture on wound healing, clinical symptoms and inflammatory response in patients with perianal abscess surgery; To evaluate the clinical efficacy.Methods:Randomized controlled trial. 120 patients after perianal abscess surgery in the hospital from August 2021 to August 2022 were selected as the observation subjects, and they were divided into three groups by the random number table method, with 40 cases in each group. On the basis of routine anti-infection therapy, external TCM application group was given Compound Huangbai Liquid coating, oral TCM administration group was given oral Xiaochuang Mixture, and combined treatment group was treated with Compound Huangbai Liquid coating + Xiaochuang Mixture. The three groups were continuously treated for 15 days. TCM symptoms scores and VAS score were performed on the 2nd day, 7th day and 15th day after surgery, and the levels of IL-6 and TNF-α were detected by ELISA. The wound healing time and carrion shedding time of patients were observed and recorded, and the clinical efficacy was evaluated.Results:The scores of perianal secretions, granulation morphology and surrounding tissue edema and score of VAS decreased in the three groups at 7 days and 15 days after surgery compared with those at 2 days after surgery ( P<0.01), and with the extension of time, the scores of perianal secretions, granulation morphology and surrounding tissue edema and VAS score from the aspects of time-point effect ( F=21.69, 134.65, 19.27, 73.15) and between-group effect ( F=7.99, 98.79, 8.68, 10.71) were declined ( P<0.01), and there was an interaction effect between the decline degree and the treatment method ( F=9.78, 59.52, 11.29, 22.48, P<0.01). The carrion shedding time [(4.63±1.31) d vs. (6.22±2.14) d, (6.17±2.09) d, F=9.16] and healing time [(27.76±3.46) d vs. (30.27±4.11) d, (31.48±4.23) d, F=9.24] were earlier in combined treatment group than those in the external TCM application group and oral TCM administration group ( P<0.01). Serum levels of IL-6 and TNF-α in the three groups at 7 and 15 days after surgery were reduced compared with those at 2 days after surgery ( P<0.01), and with the extension of time, the levels of serum IL-6 and TNF-α in the three groups decreased from the aspects of time-point effect ( F=69.36, 38.76) and between-group effect ( F=21.81, 13.50) ( P<0.01), and there was an interaction effect between the decrease degree and treatment method ( F=28.46, 23.34, P<0.01). The total effective rate was 100.0% (40/40) in combined treatment group, 80.0% (32/40) in external TCM application group and 87.2% (34/39) in oral TCM administration group ( H=8.44, P=0.015). Conclusion:The combination of Compound Huangbai Liquid coating and Xiaochuang Mixture can reduce perianal secretions, improve granulation morphology, alleviate surrounding tissue edema and wound pain, promote wound healing, and reduce inflammatory response of patients with perianal abscess surgery.

Sarcoma de Kaposi anoperineal: uma rara apresentação / Perineal Kaposi's Sarcoma: a rare presentation

O sarcoma de Kaposi é uma neoplasia maligna associada à infecção pelo herpes vírus humano 8 em doentes imunossupressos. O sarcoma de Kaposi Epidêmico é o tipo epidemiológico mais frequente e afeta indivíduos VIH-positivos. A região anoperineal é raramente envolvida e as lesões suspeitas devem ser biopsiadas para confirmação histológica. A base do tratamento é a restauração imune do doente. Relatamos o caso de um jovem, com diagnóstico recente de infeção pelo VIH, sem tratamento, que foi admitido no serviço de infectologia apresentando sintomas constitucionais, adenomegalias inguinais e extensa lesão verrucosa e ulcerada na região anoperineal. As biópsias confirmaram o diagnóstico de sarcoma de Kaposi e o doente iniciou terapia antirretroviral e quimioterapia. Houve recuperação clínica, regressão das lesões e desaparecimento das adenomegalias. Este relato objetiva alertar as equipes médicas no sentido de se incluir o sarcoma de Kaposi no diagnóstico diferencial das lesões que afetam a região anoperineal.

Kaposi's sarcoma is a malignant neoplasm associated with human herpesvirus 8 infection in immunocompromised patients. Epidemic Kaposi's sarcoma is the most common epidemiological type and affects HIV-positive patients. Perineal involvement is rare, and suspicious lesions should be biopsied to confirm histological diagnosis. Treatment consists of restoring the patient's immune system. We report the case of a young patient recently diagnosed with HIV, without treatment, who was admitted to the Department of Infectious Diseases with nonspecific symptoms, inguinal lymphadenopathy, and an extensive verrucous ulcerated lesion in the perineal region. Biopsy confirmed the diagnosis of Kaposi's sarcoma, and the patient was started on antiretroviral therapy and chemotherapy. Clinical recovery was achieved, with lesion reduction and inguinal adenopathy resolution. This case report aims to encourage physicians to include Kaposi's sarcoma in the differential diagnosis of perineal lesions.

Effect of modified incision drainage combined with thread-drawing and precise minimally invasive surgery in the treatment of anal fistula on anal defecation function and complications / 中国医师进修杂志

Objective:To compare the effects of modified incision drainage combined with thread-drawing and precise minimally invasive surgery in the treatment of anal fistula on anal defecation function and complications.Methods:A total of 105 patients with anal fistula who were diagnosed and treated in Xin′an International Hospital from December 2018 to December 2020 were collected. The patients were divided into the observation group (58 cases) and the control group (47 cases) according to surgical methods. The observation group received modified incision drainage combined with thread-drawing surgery. The control group received precise minimally invasive anal fistula surgery. The treatment outcome, anal defecation function and complications were compared between the two groups.Results:The operation time, intraoperative blood loss, first defecation time after operation, normal eating time after operation in the two groups had no significant differences ( P>0.05). The hospital stay in the observation group was significantly longer than that in the control group: (5.29 ± 1.53) d vs. (4.02 ± 1.16) d, there was statistical differences ( P<0.05). After operation, the resting pressure of the anal canal, resting rectal pressure, length of the tube high pressure belt, the maximum systolic pressure of the anal canal between the two groups had no significant differences ( P>0.05). The excellent and good rate of anal defecation function and complication rate between the two groups had no significant differences ( P>0.05). Conclusions:Modified incision drainage combined with thread-hanging surgery in the treatment of anal fistula is equivalent with precision minimally invasive surgery. Both can effectively improve the anal defecation function. The postoperative safety is good and there is no recurrence. However, the hospital stay of patients with precision minimally invasive surgery for anal fistula is relatively shorter.

Behcet's Syndrome resembling complex perianal Crohn's Disease.

Behcet's syndrome is a systemic inflammatory disorder that involves several organ systems and is exceptionally rare in the Western world. The diagnosis is frequently difficult as it resembles several other disease processes. A 23-year-old male with a previous presumptive diagnosis of Crohn's disease presented to our unit with genital ulceration. This is on a background of recurrent perianal abscesses requiring surgical drainage and seton placement. He subsequently developed a complex perianal fistula extending from the rectum to the perineum and left groin. After drainage and an unsuccessful trial of biologic immunosuppressive therapy, he developed several papulopustular cutaneous lesions and oral ulcerations. The diagnostic criteria for Behcet's syndrome was met and he was referred to a rheumatologist for ongoing management.

Ligasure Hemorrhoidectomy: Updates on Complications After an 18-Year Experience.

BACKGROUND: Hemorrhoidal disease represents one of the most common anorectal disorders in the general population. Energy devices, such as LigaSureTM scalpel, have reshaped the concept of hemorrhoid surgery and in turn, have improved patient outcomes and simplified the work of surgeon. OBJECTIVE: The study aims to evaluate the outcomes of LigaSureTM hemorrhoidectomy (LH) analyzing main post-operative complications rate, length of stay, operating time, and time to return to work. METHODS: In this monocentric descriptive study, from June 2001 to February 2019, 1454 consecutive patients, treated with LH for grade III and IV hemorrhoids, were analyzed. Complications were classified in early, late, and long-term if they occurred within 1 month, between 1 and 2 months or after 2 months, respectively. RESULTS: 90.2% of patients were treated in day surgery regimen and the mean operating time was 14.3 minutes. The post-operative pain decreased from 3.7 mean VAS on the 1st postoperative day to 0.1 mean VAS on 30th post-operative day. Early complications rate was 2.1%: urinary retention accounted for 1.8% of patients. 0.3%-of patients experienced postoperative bleeding and only one required reoperation. Late complications rate was 5.8%: anal stenosis, incomplete healing, and anal fissure were detected in 3.6%, 1.2%, and 1% of patients, respectively. The long term complications rate was 5.3%: anal fistula, soiling, perianal abscess, and recurrence were identified in 0.2%, 0.1%, 0.3%, and 4.8% of patients, respectively. CONCLUSION: LH is a safe and fast procedure with a proven minimal complication rate.

Effect of Zhitong-Rusheng Decoction on wound healing and serum fibronectin and epidermal growth factor levels after anal fistula operation / 国际中医中药杂志

Objective:To investigate the effect of Zhitong-Rusheng Decoction on wound healing and serum fibronectin (FN) and epidermal growth factor (EGF) levels after anal fistula operation. Methods:A total of 102 patients after anal fistula operation in our hospital from March 2018 to March 2020 were randomly divided into control group (51 cases) and observation group (51 cases) according to the random number table method. The control group was treated with conventional western treatment, while the observation group was treated with Zhitong-Rusheng Decoction on the basis of control group. The two groups were treated for 3 weeks. The clinical symptoms were scored before and after treatment, and the levels of serum FN and EGF were detected by ELISA. The wound healing time, hematochezia disappearance time, wound longitudinal diameter and wound area before and after treatment were observed. The clinical efficacy was evaluated after treatment. Results:The total effective rate was 98.0% (50/51) in the observation group and 72.6% (37/51) in the control group, with significant difference between the two groups ( χ2=13.209, P<0.01). After treatment, the pain degree score, wound exudation score and granulation morphology score of the observation group were significantly lower than those in the control group ( t=15.448, 21.424, 28.641, P<0.001). After treatment, the wound healing time [(6. 04 ± 1.20) d vs. (9.42 ± 1.58) d, t=12.166] and the disappearance time of hematochezia [(15.72 ± 2.86) d vs. (19.95 ± 4.33) d, t=6.862] of the observation group were significantly shorter than thosse of the control group( P<0.01). After treatment, the wound longitudinal diameter [(1.89 ± 0.31) cm vs. (2.82 ± 0.54) cm, t=10.666] and wound area [(3.26 ± 0.54) cm 2vs. (4.98 ± 1.10) cm 2, t=10. 024] of the observation group were significantly less than those in the control group ( P<0.01). The serum FN [(2.92 ± 0.50) mg/L vs. (2.45 ± 0.39) mg/L, t=5.293], EGF [(7.03 ± 1.44) μg/L vs. (5.47 ± 1.03) μg/L, t=6.293] of the observation group were significantly higher than those in the control group ( P<0.01). Conclusion:Zhitong-Rusheng Decoction on the basis of conventional treatment on patients after anal fistula operation has a good efficacy, which is conducive to wound healing, reducing clinical symptoms, and improving serum levels of FN and EGF.

Anorectal diseases in patients with Antiphospholipid syndrome: a cross-sectional study.

BACKGROUND: Hemorrhoid disease (HD) is one of the most common gastrointestinal complaints worldwide, affecting 4.4% of the general population in the United States. Since antiphospholipid syndrome (APS) may lead to intra-abdominal thrombosis, one may expect that this condition can impact the risk for HD development. Additionally, as APS patients are more prone to thrombosis and treatment with anticoagulants may increase risk of bleeding, one may also infer that rates of HD complications may be higher in this scenario. Nevertheless, no data in these regards have been published until now. The objective of the present study is to evaluate frequency of HD and describe its complications rates in antiphospholipid syndrome APS patients. METHODS: We consecutively invited patients who fulfilled APS criteria to undergo proctological examination. After examination, patients were divided in two groups, based on the presence of HD, and compared regarding different clinical manifestations and antiphospholipid profile. We performed the analysis of the data, using chi-square and Mann Whitney U when applicable and considering a significance level of 0.05. Multivariate regression analysis included age and variables with p < 0.10 in the bivariate analysis. RESULTS: Forty-one APS patients agreed to undergo proctological examination. All were female and overall median age was 43 (36-49). Seventeen (41.4%) patients were diagnosed with HD, with the following frequency distribution: 7 internal (41.2%), 4 external (23.5%) and 5 mixed hemorrhoids (29.4%). Of the internal hemorrhoids, 5 patients were classified as grade I (71.4%), 1 grade II (14.3%), and 1 grade IV (14.3%). Prior gestation (p = 0.067) and constipation (p = 0.067) correlated with a higher frequency of HD. In multivariate analysis, constipation remained as an important risk factor (OR 3.92,CI95% 1.03-14.2,p = 0.037). Five out of 17 patients (29.4%) reported anal bleeding, but it did not correlate with warfarin dose (p = 0.949). Surgical treatment was indicated for 10 patients (58.8%). Other anorectal findings were anal fissure, plicoma, condyloma and one chlamydial retitis. CONCLUSION: We found an unexpected high frequency of hemorrhoids in APS patients, with a great proportion requiring surgical treatment.

ESGAR consensus statement on the imaging of fistula-in-ano and other causes of anal sepsis.

OBJECTIVES: To develop imaging guidelines for patients with fistula-in-ano and other causes of anal sepsis. METHODS: An expert group of 13 members of the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) used a modified Delphi process to vote on a series of consensus statements relating to the imaging of patients with potential anal sepsis. Participants first completed a questionnaire to gather practice information and to help frame the statements posed. RESULTS: In the first round of voting, the expert group scored 51 statements of which 45 (88%) achieved immediate consensus. The remaining 6 statements were redrafted following input from the expert group and consensus achieved for all during a second round of voting, including an additional statement drafted. No statement was rejected due to a lack of consensus. After redrafting to improve clarity, 53 individual statements were presented. CONCLUSION: These expert consensus statements can be used to guide appropriate indication, acquisition, interpretation and reporting of medical imaging for patients with potential fistula-in-ano and other causes of anal sepsis. KEY POINTS: • Medical imaging, notably magnetic resonance imaging, is used widely for the diagnosis and monitoring of fistula-in-ano and other causes of anal and perianal sepsis. • While the indexed medical literature is clear that diagnostic accuracy is potentially excellent, this depends on competent image acquisition and interpretation. • In order to facilitate this, the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) has produced expert consensus guidelines regarding the imaging of fistula-in-ano and related conditions.

Anogenital Dermatitis in Men Who Have Sex with Men.

Evaluation of anogenital dermatitis requires a detailed history, including a sexual history. Men who have sex with men have different risk of certain infectious causes compared with men who have sex with women. Infectious causes of balanitis and anal dermatitis are easily treatable once identified. Irritant contact dermatitis is a common cause of balanitis, and avoidance of irritants, including decreased soap washing, helps many patients improve. Detailed histories of the personal products used by the patient and partner(s), including soaps, lotions, perfumes, lubricants, condoms, topical medications, hygiene sprays, personal wipes, and laundry detergent, may reveal possible irritants or contact allergens.

Perianal sepsis in neutropaenic patients with haematological malignancies: the role of magnetic resonance imaging and surgery.

BACKGROUND: Perianal sepsis occurs in up to 10% of neutropaenic patients with haematological malignancy and is associated with significant morbidity and mortality. The management of this condition is challenging in neutropaenic patients due to its atypical pathophysiology. The aim of this study is to assess the role of magnetic resonance imaging (MRI) and surgery in neutropaenic patients with perianal sepsis. METHODS: A retrospective chart review was performed on all neutropenic patients with a haematological malignancy who had a diagnosis of perianal sepsis during the inpatient admission between 2008 and 2017. Patient characteristics, symptoms, haematological data, MRI result, surgical intervention, intraoperative findings and outcomes including recurrence and mortality were collected. RESULTS: Nineteen neutropaenic patients with haematological malignancy were treated for perianal sepsis, eight (42%) patients were managed conservatively and 11 (58%) were managed surgically. Nine patients underwent MRI, which identified a collection in 88% of cases despite severe neutropaenia. In patients with a collection identified on MRI prior to surgery, 80% had a drainable collection confirmed intraoperatively. Post-operative complications included two cases of sepsis from a presumed perianal source and one death. A total of 82% of patients experienced symptom resolution after surgery compared to 88% of patients managed conservatively. CONCLUSION: This study has demonstrated that MRI is a useful diagnostic tool in evaluating perianal sepsis in patients with haematological malignancy, even during periods of severe neutropenia. We found that both conservative and surgical management strategies lead to resolution of symptoms.

Incidence and clinical impact of perianal disease in patients with ulcerative colitis: A nationwide population-based study.

BACKGROUND AND AIM: The risk and clinical impact of perianal disease (PAD) in ulcerative colitis (UC) patients have not been fully evaluated. We investigated the incidence of PAD in UC patients and compared clinical characteristics and outcomes of UC according to the presence of PAD. METHODS: We performed a nationwide population-based cohort study and a hospital-based cohort study. Using the 2010-2014 data from the Korean National Health Insurance claims database, we calculated incidence rates and standardized incidence ratios of PAD in UC patients compared with the general population. We evaluated the clinical characteristics and outcomes of UC patients with PAD in both population-based and hospital-based cohorts. To reduce clinically meaningful confounding factors, we also conducted matched analyses. RESULTS: In the population-based cohort, the incidence rate and standardized incidence ratio of PAD in UC patients were 3.74/1000 person-years (95% confidence interval, 3.25-4.31) and 2.88 (95% confidence interval, 2.50-3.32), respectively. In the hospital-based cohort, the cumulative probabilities of PAD at 1, 5, 10, and 20 years after diagnosis were 1.0%, 2.3%, 4.0%, and 6.3%, respectively. In both population-based and hospital-based cohorts, UC patients with PAD showed higher proportions of corticosteroid use and extensive colitis at diagnosis. The requirements for anti-tumor necrosis factor agents and colectomy were significantly higher in UC patients with PAD before and after matched analysis. CONCLUSIONS: The risk of PAD is higher in UC patients than in the general population. UC patients with PAD have distinct clinical features and poor outcomes, as indicated by the greater need for UC-related medications and colectomy.

Relationship between MRI findings after laparoscopic?assisted anorectal pull?through for anorectal malformations and the functional outcomes / 中华放射学杂志

Objective To explore the relationship between MRI findings and defecation function after laparoscopic?assisted anorectal pull?through for anorectal malformations. Methods A retrospective cohort study focused on the findings of MRI performed after laparoscopic?assisted anorectal pull?through for anorectal malformations and no spinal deformity was present in all patients who are currently older than 3 years. Forty?two patients aged from 3 to 16 years (median age was 4 years), whom accepted operation at 3 months to 13 years old(median age was 5 months), and MRI was carried out in 2 to 5 months after operation (median time was 3 months). The MRI manifestations including the relationship between the anorect and the high muscle complex(RAHMC), anorectal angle(AA); the relationship between the anorect and the low muscle complex(RALMC), the rectal maximum diameter(RMD), the fat tissue interposition(FTI) and the development of pelvic floor muscle(PFM) were reviewed and summarized. Statistically, the differences of MRI manifestations in different defecation function index, including the degree of voluntary bowel movements, soiling, constipation and Krickenbeck score were evaluated respectively with Chi?square test or rank sum test. Results statistically, There was significant differences among the groups with different degree of voluntary bowel movements, soiling and Krickenbeck score in the RAHMC (P<0.05), and AA was correlated with the degree of voluntary bowel movements, soiling, constipation and Krickenbeck score(P<0.05), but no significant differences was found among the groups with different defecation function index in the RALMC, the RMD, the FTI and the development of PFM(P>0.05). Conclusions The deviation of the anorect from the high muscle complex which showed in the postoperative MRI pictures suggested the poor prognosis, and well?developed pelvic floor muscles which indicated in the MRI was not the sufficient predictor for good outcome. Postoperative anorectal angle obtained in the MRI can be used as an objective indicator of prognosis.

Application value of MR sequence imaging in the diagnosis and classification of perianal abscess and anal fistula / 中国基层医药

Objective To explore the clinical value of magnetic resonance imaging( MRI) in the diagnosis and classification of perianal abscess and anal fistula.Methods Eighty patients with suspected perianal abscess and anal fistula were selected in Yuyao People＇s Hospital from May 2016 to December 2017.They were divided into general examination group and MRI group by random number table,with 40 cases in each group. The general examination group underwent ultrasound examination,and the MRI group underwent MRI examination.The detection rate of MRI examination for various types of perianal abscess and anal fistula was analyzed based on the results of operation. Results In the general examination group, the diagnostic accuracy of anal fistula supervisor, anal fistula internal orifice,perianal abscess and anal fistula branch were 65.0% (26/40),70.0% (28/40),57.5% (23/40) and 52.5% (21/40),respectively,which in the MRI group were 92.5% (37/40),77.5% (31/40),87.5% (35/40) and 95.0% (38/40),respectively.There were statistically significant differences in diagnostic accuracy of anal fistula supervisor, perianal abscess and anal fistula branch between the two groups ( χ2 =9.054,7.116,8.865, all P <0.05). The effective rate of operation in the MRI group was 67.5% (27/40),which was significantly higher than that in the general examination group [67.5% (27/40)],the difference was statistically significant(χ2 =9.935,P<0.01). Conclusion Using MRI to diagnose perianal abscess and anal fistula can accurately judge the number,involvement range,specific location and surrounding structure of the abscess and anal fistula,and has important value for clinical treatment and prognosis.
