BACKGROUND: Perianal abscess is a common condition among adults. The treatment of choice includes early and efficient drainage. The data regarding risk factors for abscess recurrence, fistula formation, and complications are limited as recent publications mainly focus on patients with inflammatory bowel disease. OBJECTIVES: To determine risk factors for abscess recurrence and fistula formation with regard to patient and surgical characteristics. METHODS: A retrospective analysis was performed on patients who presented to the emergency department and were diagnosed with perianal abscess between 2011-2020. RESULTS: We included 983 consecutive patients; 741 men, average age 43 years. Recurrence was documented in 434 cases. Crohn's disease was reported in 70, of which 50 had recurrent episodes (P < 0.0001); 121 of the 234 patients who smoked had recurrence (P = 0.0078); 8% had short symptomatic period (< 24 hours), which was a predisposing factor for recurrence, P < 0.0001. Patients in the non-recurrent group waited 2.53 hours less for surgical intervention (P < 0.0005(. The average time for recurrent episode was 18.95 ± 33.7 months. Fistula was diagnosed in 16.9% of all cases, while 11.6% were within the recurrent group. Surgical expertise of the physician did not significantly change the recurrence rate. CONCLUSIONS: Crohn's disease and smoking were the only significant risk factors for recurrence of perianal abscess. Timely intervention and drainage of sepsis should not be delayed. Involvement of more experienced surgeons did not seem to alter the natural history of the disease.

Background: Anorectal diseases and pelvic floor disorders are prevalent among the general population. Patients may present with overlapping symptoms, delaying diagnosis, and lowering quality of life. Treating physicians encounter numerous challenges attributed to the complex nature of pelvic anatomy, limitations of diagnostic techniques, and lack of available resources. This article is an overview of the current state of artificial intelligence (AI) in tackling the difficulties of managing benign anorectal disorders and pelvic floor disorders. Methods: A systematic literature review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched the PubMed database to identify all potentially relevant studies published from January 2000 to August 2023. Search queries were built using the following terms: AI, machine learning, deep learning, benign anorectal disease, pelvic floor disorder, fecal incontinence, obstructive defecation, anal fistula, rectal prolapse, and anorectal manometry. Malignant anorectal articles and abstracts were excluded. Data from selected articles were analyzed. Results: 139 articles were found, 15 of which met our inclusion and exclusion criteria. The most common AI module was convolutional neural network. researchers were able to develop AI modules to optimize imaging studies for pelvis, fistula, and abscess anatomy, facilitated anorectal manometry interpretation, and improved high-definition anoscope use. None of the modules were validated in an external cohort. Conclusion: There is potential for AI to enhance the management of pelvic floor and benign anorectal diseases. Ongoing research necessitates the use of multidisciplinary approaches and collaboration between physicians and AI programmers to tackle pressing challenges.

Anal pain can be acute (most commonly related to anal fissure, perianal abcess or fistula, perianal vein thrombosis) or chronic (functional or neuropathic) including levator ani syndrome, proctalgia fugax, pudendal nevralgia and coccygodynia. History and clinical examination are keys to diagnose acute causes. Diagnosis of chronic anal pain on the other hand is more challenging and based on thorough history and analysis of symptoms. The aim of this article is to discuss the main etiologies and treatments of acute and chronic anal pain, including an update on the management and treatment of hemorrhoidal disease and postoperative pain management.
La douleur anale peut être de survenue aiguë (le plus fréquemment en lien avec une fissure anale, un abcès ou fistule anale, ou une thrombose des veines périanales) ou chronique (fonctionnelle ou neuropathique), comportant le syndrome du releveur de l'anus, la proctalgia fugax, la névralgie du pudendal et les coccygodynies. Le diagnostic d'une douleur anale aiguë est rapidement posé grâce à l'anamnèse et surtout l'examen clinique. Les causes chroniques sont en revanche plus difficiles à diagnostiquer et nécessitent un interrogatoire détaillé avec une analyse approfondie des symptômes. Le but de cet article est d'explorer le traitement des étiologies de douleur anale aiguë, de pouvoir reconnaître une grande part des douleurs anales chroniques, sans oublier une mise à jour sur la maladie hémorroïdaire avec la prévention et gestion des douleurs postopératoires.

The ability to experience pleasurable sexual activity is important for human health. Receptive anal intercourse (RAI) is a common, though frequently stigmatized, pleasurable sexual activity. Little is known about how diseases of the colon, rectum, and anus and their treatments affect RAI. Engaging in RAI with gastrointestinal disease can be difficult due to the unpredictability of symptoms and treatment-related toxic effects. Patients might experience sphincter hypertonicity, gastrointestinal symptom-specific anxiety, altered pelvic blood flow from structural disorders, decreased sensation from cancer-directed therapies or body image issues from stoma creation. These can result in problematic RAI - encompassing anodyspareunia (painful RAI), arousal dysfunction, orgasm dysfunction and decreased sexual desire. Therapeutic strategies for problematic RAI in patients living with gastrointestinal diseases and/or treatment-related dysfunction include pelvic floor muscle strengthening and stretching, psychological interventions, and restorative devices. Providing health-care professionals with a framework to discuss pleasurable RAI and diagnose problematic RAI can help improve patient outcomes. Normalizing RAI, affirming pleasure from RAI and acknowledging that the gastrointestinal system is involved in sexual pleasure, sexual function and sexual health will help transform the scientific paradigm of sexual health to one that is more just and equitable.

Perianal complications are common and morbid in children with Crohn's disease. In this review, we describe the epidemiology, the presentation and diagnosis, evaluation and management. We focus on updates such as the increasing frequency of biologic medications and MRI for evaluation. We also highlight controversies on the timing and approaches to surgical techniques. Finally, perianal disease requires the coordination of multidisciplinary care with nursing, radiology, gastroenterology, and surgery to optimize outcomes - both medical and patient-centered.

Bowel transit disturbances favored by pregnancy and injuries during childbirth would be triggering or aggravating factors for anal pathologies. The objective of this work was to study the epidemiology, diagnosis, and treatment of anal pathologies during pregnancy and 6 weeks after delivery. We carried out a prospective, multi-centric, and analytical study in 10 obstetric units in Bamako from June 1st, 2019, to May 31st, 2020. After informed consent, we enrolled all first-trimester pregnant women admitted to the hospitals and who were followed up through the postpartum. We conducted a rectal examination in each participant and an anoscope in those with an anal symptom. Hemorrhoidal diseases were diagnosed in the case of external hemorrhoids (thrombosis or prolapse) or internal hemorrhoids. During the study period, we followed up 1,422 pregnant women and we found 38.4% (546) with anal pathologies (hemorrhoidal diseases in 13% (192), anal fissure in 10.5% (150) and anal incontinence in 8.6% (123). Risk factors for the hemorrhoidal disease were age of patient ≥30 years old aRR=5.77, 95% CI 4.57-7.34; p=0.000; a existence of chronic constipation aRR=2.61, 95% CI 1.98-3.44; p=0.000; newborn weight >3500 g aRR= 1.61, 95% CI 1.25-2.07; p=0.000 and fetal expulsion time >20 minutes aRR= 6.04, 95% CI 5.07-7.27; p=0.000. The clinical signs observed were constipation, anal pain, bleeding, and pruritus. The treatment was based on counseling on hygiene and diet, the use of laxatives, local topicals, and analgesics along perineal rehabilitation. Anal pathologies were common during pregnancy and 6 weeks after delivery. Pregnant women must be screened systematically for such pathologies. Early diagnostic and appropriate treatment would reduce serious complications.

En este reporte presentamos tres pacientes en quienes ocurrieron condiciones inflamatorias perianales tardías, luego de la administración de sustancias modeladoras no identificadas en los glúteos. El diagnóstico inicial y supuesto no fue correcto, ya que no se investigó durante la evaluación preliminar el antecedente de la administración de elementos modeladores. Recomendamos que los pacientes con patologías inflamatorias del ano, sobre todo aquellos cuyo curso es extraño, se les pregunte acerca de la administración de agentes modeladores en los glúteos. Esta práctica puede contribuir a la eficacia del diagnóstico de manifestaciones perianales caracterizadas por flogosis, que se presentan de forma inusual. (AU)
In this report we present three patients in which late perianal inflammatory conditions occurred after administration of unidentified modeling agents to the buttocks. The initial diagnosis was not correct because of the administration of modeling agents was not investigated during the initial eval-uation. We recommend inquiring patients with inflammatory pathologies of the anus, especially those whose course is unusual, about the adminis-tration of modeling agents to the buttocks. This approach can contribute to the efficiency of the diagnosis of perianal complaints characterized by inflammation, but rare in its appearance. (AU)

Anorectal emergencies are rare presentations of common anorectal disorders, and surgeons are often called on to assist in their diagnosis and management. Although most patients presenting with anorectal emergencies can be managed nonoperatively or with a bedside procedure, surgeons must also be able to identify surgical anorectal emergencies, such as gangrenous rectal prolapse. This article provides a review of pertinent anatomy; examination techniques; and workup, diagnosis, and management of common anorectal emergencies including thrombosed hemorrhoids, incarcerated hemorrhoids, anal fissure, anorectal abscess, rectal prolapse, and pilonidal abscess and unique situations including rectal foreign body and anorectal sexually transmitted infections.

OBJECTIVE: To study the influence of clinical characteristics and diagnosis and treatment methods of perianal abscess on postoperative recurrence or formation of anal fistula to provide a basis for selecting appropriate surgical and inspection methods for clinical treatment of perianal abscess in the future. METHODS: The clinical data of 394 patients with perianal abscesses were collected, the influencing factors were investigated, and univariate analysis and multivariate logistic regression analysis were performed to further determine the risk factors affecting the prognosis of perianal abscess. RESULTS: The results showed that the rate of preoperative blood routine results in the uncured group was higher (51.16%) than in the cured group (35.61%); the rate of high abscess space in the uncured group (23.26%) was higher than in the cured group (9.11%); the proportion of patients in the uncured group who underwent magnetic resonance imaging (MRI) before surgery (27.90%) was lower than in the cured group (45.30%); the proportion of patients in the uncured group who underwent simple drainage (51.16%) was higher than in the cured group (28.49%). The two groups had significant differences in perineal MRI examination, surgical method, preoperative blood routine, and abscess space (p = 0.030, p = 0.002, p = 0.047 and p = 0.010, respectively). Based on the results of univariate analysis and multivariate logistic regression analysis, the extent of the abscess cavity (OR = 2.544, 95%CI = 1.087-5.954, p = 0.031) and the surgical method (OR = 2.180, 95%CI = 1.091-4.357, p = 0.027) were independent influencing factors for postoperative recurrence of perianal abscess or anal fistula. CONCLUSION: Preoperative assessment of the abscess range and precise intraoperative methods to resolve the infection of the abscess glands in the internal mouth can effectively improve the cure rate.

The gold-standard procedure for anal canal examination is anoscopy. Nonetheless, patients are referred for a colonoscopy for many reasons, and a routine exam might provide an opportunity to diagnose anal pathologies, such as hemorrhoids, anal fissures, anal polyps, condylomas, and anal squamous cell carcinoma. It is important to know the main features of these conditions and relevant information to report in order to help guide patient treatment and follow-up.

Levator ani syndrome (LAS), also known as levator ani spasm, puborectalis syndrome, chronic proctalgia, pyriformis syndrome and pelvic tension myalgia, produces chronic anal pain. The levator ani muscle is susceptible to the development of myofascial pain syndrome, and trigger points may be elicited on physical examination. The pathophysiology remains to be fully delineated. The diagnosis of LAS is suggested primarily by the clinical history, physical examination and the exclusion of organic disease that can produce recurrent or chronic proctalgia. Digital massage, sitz bath, electrogalvanic stimulation and biofeedback are the treatment modalities most frequently described in the literature. Pharmacological management includes non-steroidal anti-inflammatory medications, diazepam, amitriptyline, gabapentin and botulinum toxin. The evaluation of these patients can be challenging due to a diversity of causative factors. The authors present the case of a nulliparous woman in her mid-30s presenting with acute onset of lower abdominal and rectal pain radiating to her vagina. There was no history of trauma, inflammatory bowel disease, anal fissure or altered bowel habit. Each pain episode lasted longer than 20 min and was exacerbated by sitting. Neurological examination showed no evidence of neurological dysfunction. Rectal examination was unremarkable. During vaginal examination, palpation of the levator ani muscles elicited pain indicating pelvic floor dysfunction. Laboratory investigations including a full blood count and C reactive protein were within normal range. Further investigation with a transabdominal ultrasound scan, CT of the abdomen and pelvis and MRI of the lumbar spine were unremarkable. She commenced treatment with amitriptyline 20 mg once daily. She was referred for pelvic floor physiotherapy. Functional pain syndromes, such as LAS, should be regarded as diagnoses of exclusion and considered only after a thorough evaluation has been performed to rule out structural causes of pain. Knowledge of the pelvic floor and pelvic wall muscles may enable the physician to identify LAS, a possible cause of chronic pelvic pain.

BACKGROUND: Men who have sex with men (MSM) without HIV are known to be at elevated relative risk for Human papillomavirus (HPV)-associated anal cancer in comparison to men who have sex with women (MSW), but are poorly characterized in terms of anal cancer incidence due to absence of reporting of sexual behavior/identity at a population-level. METHODS: By combining age-specific statistics from multiple data sources (anal cancer incidence among all males; anal cancer incidence among MSM and MSW with HIV; population size of men with HIV by sexual orientation), we developed a mathematical model to estimate anal cancer incidence, annual number of cases, and proportion by (a) sexual orientation (MSM versus MSW), (b) HIV status, and (c) age (<30, 30-44, 45-59, and ≥60 years). RESULTS: Anal cancer incidence (per 100 000) among MSM without HIV was 1.4 (95% uncertainty interval [UI], 0.6 to 2.3), 17.6 (95% UI = 13.8-23.5), and 33.9 (95% UI = 28.3-42.3), at ages 30-44, 45-59 and ≥60 years, respectively. 19.1% of all male anal cancer occurred in MSM without HIV, increasing from 4% of anal cancer diagnosed at 30-44 years to 24% at ≥60 years; 54.3% occurred in MSW without HIV (increasing from 13% at age 30-44 to 67% at >60 years), and the remaining 26.6% in men (MSM and MSW combined) with HIV (decreasing from 83% at age 30-44 to 9% at >60 years). CONCLUSIONS: These findings should inform anal cancer prevention recommendations in male risk groups, including, for the first time, for the important group of MSM without HIV.
