Abstract
Anal suppurative processes are commonly encountered in surgical practice. While the initial therapeutic intervention is philosophically straightforward (incision and drainage), drainage of the appropriate space and treatment of the subsequent fistula in ano require a thorough understanding of perianal anatomy and nuanced decision making. Balancing the risk of fecal incontinence with simple fistulotomy versus the higher risk of fistula recurrence with all sphincter-sparing fistula treatments can be a challenge for surgeons and patients alike.

Abstract
BACKGROUND Timely incision and drainage (I&D) is first line management for anorectal abscesses. We aimed to define current practices in anorectal abscess management and identify factors associated with abscess recurrence and fistula formation. METHODS Index episodes of anorectal abscesses treated with I&D in 2014-2018 at a multi-hospital healthcare system were included. Association with one-year abscess recurrence or fistula formation was evaluated using Cox proportional hazard regression. Fistulae were captured only among patients without fistulae at the index operation. RESULTS A total of 458 patients met study criteria. One-year rate of abscess recurrence or fistula formation was 20.3%. When compared to bedside procedures, drainage in the operating room was associated with a reduced risk of either recurrence or fistula formation (aHR 0.20 [95%CI 0.114-0.367]). CONCLUSIONS Improved exposure and patient comfort in the operating room may allow more complete drainage contributing to decreased rates of abscess recurrence or fistula formation.

Abstract
There are many benign anorectal disorders, which can make patients seek care. In low-resource settings, the incidence of those pathologies is not different from the industrialized and western world. However, an interesting difference colorectal surgeons and gastroenterologists can face is the fact that many patients do not seek help or are not aware and have little opportunities to be helped. Latin America population is estimated to be around 8% of the world population, with Brazil having the largest percentage. Infectious diseases, which were previously under control or were steadily declining, have emerged. For example, we have seen resurgence of dengue, malaria, and syphilis in pregnancy, as well as other sexually transmitted diseases that can affect the anorectal region. In this article, we will address the most common benign anorectal disorders.

Recurrence and incidence of fistula after urgent drainage of an anal abscess. Long-term results. Cir Esp 2021; 100:25-32.

Abstract
INTRODUCTION Anal abscess is the most frequent urgent proctological problem. The recurrence rate and reported incidence of fistula after drainage and debridement of an anal abscess is widely variable. The objective of this study is to analyse the long-term recurrence rate and the incidence of fistula after drainage and urgent debridement of an anal abscess. METHODS Retrospective observational study of a prospective cohort with anal abscess of cryptoglandular origin. All patients (n = 303) were evaluated two months and one year after the intervention. At the 5th year, all the medical records were reviewed and a telephone call or appointment was made for an assessment if necessary. Specific antecedents of anal pathology, abscess characteristics, time and type of recurrence, presence of symptoms in the first revision and presence of clinical and/or ultrasound fistula were recorded. RESULTS Mean follow-up 119.7 months. Recurrence rate 48.2% (82.2% in the first year). Two hundred twenty-two ultrasounds performed. Incidence of ultrasound fistula: 70% symptomatic vs. 2.4% asymptomatic (p < 0.001). Global incidence of fistula 40.3%. The history of anal pathology and the presence of symptoms in the postoperative review significantly increase the possibility of recurrence (p < 0.001). The fistula is statistically more frequent if the abscess recurs (p < 0.001). CONCLUSION After drainage and debridement of an anal abscess, half of the patients relapse and 40% develop fistula especially in the first year, so longer follow-ups are not necessary. Endoanal ultrasound for the evaluation of the presence of fistula is highly questionable in the absence of signs or symptoms.

Abstract
Anorectal emergencies comprise a wide variety of diseases that share common symptoms, i.e., anorectal pain or bleeding and might require immediate management. While most of the underlying conditions do not need inpatient management, some of them could be life-threatening and need prompt recognition and treatment. It is well known that an incorrect diagnosis is frequent for anorectal diseases and that a delayed diagnosis is related to an impaired outcome. This paper aims to improve the knowledge and the awareness on this specific topic and to provide a useful tool for every physician dealing with anorectal emergencies.The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the boards of the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the WSES-AAST-WJES Consensus Conference on Anorectal Emergencies, and for each statement, a consensus among the WSES-AAST panel of experts was reached. We structured our work into seven main topics to cover the entire management of patients with anorectal emergencies and to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

Abstract
Abstract
Background Perianal fistula is among the most common anorectal diseases encountered in adults, men are more prone to be affected than women. There is a close relationship of abscess and fistula in etiology, anatomy, pathophysiology, therapy, complications and morbidity, it is appropriate to consider them as one entity.
Aim of study To determine the incidence of fistula formation and recurrent abscess in a sample of Iraqi patients in Baghdad and decide whether primary fistulotomy should be performed at the time of incision and drainage of perianal abscesses.
Patients and methods A retrospective study of 68 patients with perianal abscess operations conducted in Baghdad. They underwent incision and drainage under either local or general anesthesia at Al-Kindy Teaching Hospitals and private hospitals over a 15-year period from January 2000 to December 2015. Their ages ranged from 20 to 68 years (40.21 ± 1.34) males (63/68) (92.64%) were more than females (5/68) (7.35%). Patients were treated with incision over the abscess under anesthesia and drainage of the abscess was done. The patients were followed up for an average 18 months (range 12–24 months) after abscess drainage or until a fistula appeared and abscess recurrence.
Results The study group comprised of 68 (92.64%) patients with perianal abscess with a median age 39 years (range 20–68 years). The mean follow-up period was identified to be 18 months (range 12–24 months). Males (63/68) (92.64%) were more than females (5/68) (7.35%). The incidence of fistula formation after follow up, the patients with perianal abscess after incision and drainage was 31/68 (45.58%) and males (30/31) (44.11%) were more than females (1/31) (1.47%). The most common site was posterior then left lateral position. The percentage of patients with recurrent abscess n = 6 (8.82%)were lower than fistula formation n = 31 (45.58%). The percentage of males n = 4/6 (5.88%) were more than females 2/6 (2.94%).
Conclusions The incidence of anal fistula in a sample of Iraqi patients with perianal abscess was 45.58% and percentage of recurrence of perianal abscess was 8.82%. To avoid division of anal sphincter muscle, secondary fistulotomy is advised to be done later when anal fistula will be formed.

Abstract
INTRODUCTION Postoperative recurrence and related complications are common and related to poor outcomes in patients with anal fistula (AF). Due to being associated with short-term and long-term cure rates, perioperative complications have received widespread attention following AF surgery. This study aims to identify a set of predictive factors to develop risk prediction models for recurrence and related complications following AF surgery. We plan to develop and validate risk prediction models, using information collected through a WeChat patient-reported questionnaire system combined with clinical, laboratory and imaging findings from the perioperative period until 3-6 months following AF surgery. METHODS AND ANALYSIS This is a prospective hospital-based cohort study using a linked database of collected health data as well as the follow-up outcomes for all adult patients who suffered from AF at a tertiary referral hospital in Shanghai, China. We will perform logistic regression models to predict anal fistula recurrence (AFR) as well as related complications (eg, wound haemorrhage, faecal impaction, urinary retention, delayed wound healing and unplanned hospitalisation) during and after AF surgery, and machine learning approaches will also be applied to develop risk prediction models. This prospective study aims to develop the first risk prediction models for AFR and related complications using multidimensional variables. These tools can be used to warn, motivate and empower patients to avoid some modifiable risk factors to prevent postoperative complications early. This study will also provide alternative tools for the early screening of high-risk patients with AFR and related complications, helping surgeons better understand the aetiology and outcomes of AF in an earlier stage. ETHICS AND DISSEMINATION The study was approved by the Institutional Review Board of Shuguang Hospital affiliated with Shanghai University of Traditional Chinese Medicine (approval number: 2019-699-54-01). The results of this study will be submitted to international scientific peer-reviewed journals or conferences in surgery, anorectal surgery or anorectal diseases.

Abstract
BACKGROUND The association between body mass index (BMI) and recurrence of anorectal abscess remains controversial. This study investigated the exact relationship between BMI and anorectal abscess recurrence or anal fistula formation following initial surgery. MATERIAL AND METHODS This was a retrospective registry-based study conducted at the First Affiliated Hospital of Guizhou University of Chinese Medicine. Patients treated for anorectal abscess from 01/2015 to 03/2016 were included. Clinical data and time to recurrence were recorded. The Cox regression model was used to estimate the association between BMI and recurrence. RESULTS A total of 790 patients were operated on during the study period. The average age of the participants was 38.3±11.6 years, and 83.2% were male. Median follow-up was 27 (range, 1-38) months. Compared with the low BMI (range, 15.7-22.8 kg/m²) patients, the high BMI (range, 26.0-40.6 kg/m²) patients showed higher risk of recurrence (HR=1.75, 95% CI: 1.15-2.67). In the non-adjusted model, high BMI was found to be positively correlated with recurrence (HR=1.62, 95% CI: 1.10-2.40, P=0.02), and a stronger association was found in the fully adjusted model (HR=1.75, 95% CI: 1.15-2.67, P=0.01). BMI was also used as a continuous variable for sensitivity analysis, and a similar trend was observed (P=0.01 for trend). CONCLUSIONS Elevated BMI is an independent risk factor of anorectal abscess recurrence and for increased risk of abscess recurrence or anal fistula formation.

Abstract
BACKGROUND Despite a burgeoning literature during the last two decades regarding perioperative risk management of anal fistula, little is known about its risk factors that influence postoperative recurrence. We performed a meta-analysis to summarize and assess the credibility of evidence of potential risk factors for anal fistula recurrence (AFR) after surgery. METHODS Pubmed and EMBASE without language restriction were searched from inception to April 2018 that reported risk factors which predisposed recurrence after anal fistula surgery. We excluded studies that involved patients with anal fistula associated with Crohn's disease. MOOSE guidelines were followed when this meta-analysis was performed. We used random-effects models to pool relative risks (RRs) with 95% confidence intervals (CIs). Evidence from observational studies was graded into high-quality (Class I), moderate-quality (Class II/III) and low-quality (Class IV) based on Egger's P value, total sample size and between-study heterogeneity. RESULTS Of 3514 citations screened, 20 unique observational studies comprising 6168 patients were involved in data synthesis. High-quality evidence showed that AFR was associated with high transsphincteric fistula (RR, 4.77; 95% CI, 3.83 to 5.95), internal opening unidentified (RR, 8.54; 95% CI, 5.29 to 13.80), and horseshoe extensions (RR, 1.92; 95% CI, 1.43 to 2.59). Moderate-quality evidence suggested an association with prior anal surgery (RR, 1.52; 95% CI, 1.04 to 2.23), seton placement surgery (RR, 2.97; 95% CI, 1.10 to 8.06), and multiple fistula tract (RR, 4.77; 95% CI, 1.46 to 15.51). High-quality evidence demonstrated no significant association with gender or smoking; moderate-quality evidence also suggested no association with age, tertiary referral, alcohol use, diabetes mellitus, obesity, preoperative seton drainage, high internal opening, postoperative drainage, mucosal advancement flap surgery, supralevator extensions, location or type of anal fistula. CONCLUSION Several patient, surgery and fistula-related factors are significantly associated with postoperative AFR. These findings strengthen clinical awareness of early warning to identify patients with high-risk disease recurrence for AFR.

Abstract
Abstract
Background
Progression from anorectal abscess to fistula is poorly described and it remains unclear which patients develop a fistula following an abscess. The aim was to assess the burden of anorectal abscess and to identify risk factors for subsequent fistula formation.
Methods
The Hospital Episode Statistics database was used to identify all patients presenting with new anorectal abscesses. Cox regression analysis was undertaken to identify factors predictive of fistula formation.
Results
A total of 165 536 patients were identified in the database as having attended a hospital in England with an abscess for the first time between 1997 and 2012. Of these, 158 713 (95·9 per cent) had complete data for all variables and were included in this study, the remaining 6823 (4·1 per cent) with incomplete data were excluded from the study. The overall incidence rate of abscess was 20·2 per 100 000. The rate of subsequent fistula formation following an abscess was 15·5 per cent (23 012 of 148 286) in idiopathic cases and 41·6 per cent (4337 of 10 427 in patients with inflammatory bowel disease (IBD) (26·7 per cent coded concurrently as ulcerative colitis; 47·2 per cent coded as Crohn's disease). Of all patients who developed a fistula, 67·5 per cent did so within the first year. Independent predictors of fistula formation were: IBD, in particular Crohn's disease (hazard ratio (HR) 3·51; P < 0·001), ulcerative colitis (HR 1·82; P < 0·001), female sex (HR 1·18; P < 0·001), age at time of first abscess 41–60 years (HR 1·85 versus less than 20 years; P < 0·001), and intersphincteric (HR 1·53; P < 0·001) or ischiorectal (HR 1·48; P < 0·001) abscess location compared with perianal. Some 2·9 per cent of all patients presenting with a new abscess were subsequently diagnosed with Crohn's disease; the median time to diagnosis was 14 months.
Conclusion
The burden of anorectal sepsis is high, with subsequent fistula formation nearly three times more common in Crohn's disease than idiopathic disease, and female sex is an independent predictor of fistula formation following abscess drainage. Most fistulas form within the first year of presentation with an abscess.

Antibiotic therapy for prevention of fistula in-ano after incision and drainage of simple perianal abscess: A randomized single blind clinical trial. Surgery 2017; 162:1017-1025. [PMID: 28822559 DOI: 10.1016/j.surg.2017.07.001] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2016] [Revised: 07/03/2017] [Accepted: 07/04/2017] [Indexed: 01/26/2023]
Abstract
BACKGROUND Much controversy exists regarding the role of antibiotics in the development of fistula in-ano after incision and drainage. We evaluated the role of postoperative antibiotics in the prevention of fistula in-ano after incision and drainage of perianal abscess. METHODS In a randomized single blind clinical trial study, 307 patients were randomly selected from those referring for incision and drainage of perianal abscess at Shahid Faghihi Hospital, Shiraz, Iran, during September 2013 to September 2014. Patients were allocated randomly either to receive 7 days of oral metronidazole and ciprofloxacin in addition to their standard care or to only receive standard care without any antibiotics after they were discharged from the hospital. Patients were followed for 3 months and final results were evaluated. The study was registered at the clinical trial registry (www.irct.ir; Irct201311049936n7). RESULTS Seven patients were lost to follow-up. Those who used prophylactic antibiotics (n = 155) had significantly lower rates of fistula formation compared with those who did not use any medication (n = 144; P < .001). Men had higher rates of fistula formation (P = .002). Patients who used more cigarettes had higher rates of fistula development (P = .001). In the univariate analysis, only postoperative antibiotic use showed a protective role against fistula formation (odds ratio = 0.426; confidence interval, 0.206-0.881). In the regression analysis postoperative antibiotic use remained protective against fistula development (odds ratio = 0.371; confidence interval, 0.196-0.703), furthermore male sex presented as a risk factor for developing fistula in-ano (odds ratio = 3.11; confidence interval, 1.31-7.38). CONCLUSION Postoperative prophylactic antibiotic therapy including ciprofloxacin and metronidazole play an important role in preventing fistula in-ano formation. Considering the complications of fistula in-ano formation and the minor side effects of antibiotic therapy, based on our results, a 7-10 course of postoperative antibiotics is advised after incision and drainage of perianal abscess.

Abstract
BACKGROUND The incidence of anal abscess and fistula is relatively high, and the condition is most common in young men. METHODS This is a revised version of the German S3 guidelines first published in 2011. It is based on a systematic review of pertinent literature. RESULTS Cryptoglandular abscesses and fistulas usually originate in the proctodeal glands of the intersphincteric space. Classification depends on their relation to the anal sphincter. Patient history and clinical examination are diagnostically sufficient in order to establish the indication for surgery. Further examinations (endosonography, MRI) should be considered in complex abscesses or fistulas. The goal of surgery for an abscess is thorough drainage of the focus of infection while preserving the sphincter muscles. The risk of abscess recurrence or secondary fistula formation is low overall. However, they may result from insufficient drainage. Primary fistulotomy should only be performed in case of superficial fistulas. Moreover, it should be done by experienced surgeons. In case of unclear findings or high fistulas, repair should take place in a second procedure. Anal fistulas can be treated only by surgical intervention with one of the following operations: laying open, seton drainage, plastic surgical reconstruction with suturing of the sphincter (flap, sphincter repair, LIFT), and occlusion with biomaterials. Only superficial fistulas should be laid open. The risk of postoperative incontinence is directly related to the thickness of the sphincter muscle that is divided. All high anal fistulas should be treated with a sphincter-saving procedure. The various plastic surgical reconstructive procedures all yield roughly the same results. Occlusion with biomaterial results in lower cure rate. CONCLUSION In this revision of the German S3 guidelines, instructions for diagnosis and treatment of anal abscess and fistula are described based on a review of current literature.

Abstract
OBJECTIVE Anorectal abscess is a clinical condition frequently encountered in daily surgical practice and recurrences may occur despite treatment with adequate incision and drainage. The primary aim of this study was to analyze the variables that may have resulted in recurrent anorectal abscess, retrospectively. MATERIAL AND METHODS Ninety-three patients out of 149 patients who underwent surgery for anorectal abscess at our center between 2011-2012 were included in this study. Data regarding age, gender, presence of recurrence, time to recurrence, abscess type, presence of fistula, fistula type, drain usage, length of hospital stay and follow-up duration were retrospectively recorded. RESULTS Patients were divided into two groups: the recurrence group and the treatment group. Eleven patients (11.8%) had a recurrence and the median time to recurrence was 3 months. None of the variables evaluated were found to be significantly associated with the presence of recurrence. CONCLUSION Variables such as age, gender, type of abscess, presence of fistula or drain usage were not associated with the development of recurrence in patients who underwent incision and drainage of an anorectal abscess.

Abstract
Perianal abscess is a common disease. Due to the special anatomical position, management of perianal abscess is still controversial. Especially, the treatment of deep perianal abscess is very difficult, because it is difficult to confirm the relationship among internal opening, extent of deep anorectal abscess and anorectal sphincters. Correct treatment of the internal opening and extent of deep anorectal abscess is the key to success. Treating the fistula and the abscess at the same time by incision and drainage may reduce the likelihood of recurrent abscess and the need for repeat surgery. However, this could affect sphincter function in some patients who may not later develop a fistula-in-ano. The results of current treatments for perianal abscess are not very satisfactory. More studies are needed in future.

Abstract
Benign anorectal diseases, such as anal abscesses and fistula, are commonly seen by primary care physicians, gastroenterologists, emergency physicians, general surgeons, and colorectal surgeons. It is important to have a thorough understanding of the complexity of these 2 disease processes so as to provide appropriate and timely treatment. We review the pathophysiology, presentation, diagnosis, and treatment options for both anal abscesses and fistulas.

Abstract
Conventional treatment of anal abscess by a simple drainage continues to be routine in many centers despite retrospective and randomized data showing that primary fistulotomy at the time of abscess drainage is safe and efficient. The purpose of this study is to report the long-term results of fistulotomy in the treatment of anal abscesses. This is a prospective nonrandomized study of 165 consecutive patients treated for anal abscess in University Hospital Hassan II, Fez, Morocco, between January 2005 and December 2010. Altogether 102 patients were eligible to be included in the study. Among them, 52 were treated by a simple drainage and 50 by drainage with fistulotomy. The results were analyzed in terms of recurrence and incontinence after a median follow-up of 3.2 years (range 2-6 years). The groups were comparable in terms of age, gender distribution, type and size of abscess. The recurrence rate after surgery was significantly higher in the group treated by drainage alone (88 %) compared to other group treated by drainage and fistulotomy (4, 8 %) (p < 0.0001). However, there was a tendency to a higher risk of fecal incontinence in the fistulotomy group (5 % vs 1 %), although this difference was not significant (p = 0.27). In the group treated by drainage and fistulotomy, high fistula tract patients are more prone to develop incontinence and recurrence, mainly within the first year. A long-term follow-up seems not to influence the results of fistulotomy group. These findings confirm that fistulotomy is an efficient and safe treatment of anal abscess with good long-term results. An exception is a high fistula, where fistulotomy may be associated with a risk of recurrence and incontinence.

Abstract
BACKGROUND The incidence of anal abscess is relatively high, and the condition is most common in young men. METHODS A systematic review of the literature was undertaken. RESULTS This abscess usually originates in the proctodeal glands of the intersphincteric space. A distinction is made between subanodermal, intersphincteric, ischioanal, and supralevator abscesses. The patient history and clinical examination are diagnostically sufficient to establish the indication for surgery. Further examinations (endosonography, MRI) should be considered in recurrent abscesses or supralevator abscesses. The timing of the surgical intervention is primarily determined by the patient's symptoms, and acute abscess is generally an indication for emergency treatment. Anal abscesses are treated surgically. The type of access (transrectal or perianal) depends on the abscess location. The goal of surgery is thorough drainage of the focus of infection while preserving the sphincter muscles. The wound should be rinsed regularly (using tap water). The use of local antiseptics is associated with a risk of cytotoxicity. Antibiotic treatment is only necessary in exceptional cases. Intraoperative fistula exploration should be conducted with extreme care if at all; no requirement to detect fistula should be imposed. The risk of abscess recurrence or secondary fistula formation is low overall, but they can result from insufficient drainage. Primary fistulotomy should only be performed in case of superficial fistulas and by experienced surgeons. In case of unclear findings or high fistulas, repair should take place in a second procedure. CONCLUSION In this clinical S3 guideline, instructions for diagnosis and treatment of anal abscess are described for the first time in Germany.
