Abstract
Observational studies have reported an association between inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), and hemorrhoids (HEM). However, the presence of a causal relationship within this observed association remains to be confirmed. Consequently, we utilized the Mendelian randomization (MR) method to assess the causal effects of IBD on hemorrhoids. We validated the association between IBD and hemorrhoids in humans based on genome-wide association studies (GWAS) data. To investigate the causal relationship between IBD and hemorrhoids, we performed a two-sample Mendelian randomization study using training and validation sets. The genetic variation data for IBD, CD, UC, and hemorrhoids were derived from published genome-wide association studies (GWAS) of individuals of European. Two-sample Mendelian randomization and Multivariable Mendelian randomization (MVMR) were employed to determine the causal relationship between IBD (CD or UC) and hemorrhoids. Genetically predicted overall IBD was positively associated with hemorrhoids risk, with ORs of 1.02 (95% CIs 1.01-1.03, P = 4.39 × 10-4) and 1.02 (95% CIs 1.01-1.03, P = 4.99 × 10-5) in the training and validation sets, respectively. Furthermore, we found that CD was positively associated with hemorrhoids risk, with ORs of 1.02 (95% CIs 1.01-1.03, P = 4.12 × 10-6) and 1.02 (95% CIs 1.01-1.02, P = 3.78 × 10-5) for CD in the training and validation sets, respectively. In addition, we found that UC in the training set was positively associated with hemorrhoids risk (ORs 1.02, 95% CIs 1.01-1.03, P = 4.65 × 10-3), while no significant causal relationship between UC and hemorrhoids was shown in the validation set (P > 0.05). However, after MVMR adjustment, UC in the training set was not associated with an increased risk of hemorrhoids. Our study showed that there is a causal relationship between CD and hemorrhoids, which may suggest that clinicians need to prevent the occurrence of hemorrhoids in CD patients.

Abstract
BACKGROUND Perianal abscess is a clinical infective and/or inflammatory collection in the perianal region, one entity of a large group of anal and perianal disorders. Perianal abscesses are often seen as a complication of grade 2 and grade 4 perianal fistulas from St. James's University Hospital classification. Several imaging modalities have been tried in the past for adequate assessment of perianal abscess with contrast-enhanced magnetic resonance imaging (CE-MRI) providing the most accurate results. Diffusion-weighted imaging (DWI) is an emerging sequence that can provide comparable results to CE-MRI in diagnosing and characterizing perianal abscess. The main objective of this study is to assess the role of DWI in adequate identification and assessment of perianal abscess and compare the final results with contrast-enhanced images. METHODS Twenty patients with complicated perianal fistula with clinically suspected perianal abscess were evaluated with DWI and CE-MRI. This study was a comparative cross-sectional study conducted in the Department of Radiodiagnosis and Imaging, All India Institute of Medical Sciences, Bhopal, India. Chi-square test was done to find the association between categorical variables. Kappa test was used to find the agreement between two different tests. Receiver operating characteristics (ROC) analysis was done to estimate the area under the curve in predicting the outcome. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were used to measure the validity of the tests. RESULTS DWI is a very sensitive MRI sequence and is equivalent to CE-MRI to detect the location and analyzing the loco-regional extent of abscess in complicated perianal fistula cases. DWI is also very sensitive and superior to T2 short tau inversion recovery (STIR) in differentiating perianal abscess from perianal inflammation without abscess. CONCLUSION DWI can be used as an alternative to post-contrast fat-suppressed MRI in precisely defining the location and extent of anal and perianal abscesses and disease activity in complicated fistula cases.

Abstract
Cayratia japonica ointment has been used for many years to promote wound healing after perianal abscess surgery. This study aimed to determine the skin-permeable and skin-retainable components of Cayratia japonica ointment after topical application to intact or broken skin via UPLC-Q-TOF-MS/MS analysis and in vitro transdermal assay. Moreover, a combination of semi-quantitative and molecular docking analyses was performed to identify the main active components of the Cayratia japonica ointment and the probable phases of the wound healing process that they act on. Modified vertical Franz diffusion cells and abdominal skin of rats were selected for the in vitro transdermal study. Mass spectrometry data were collected in both positive and negative ion modes. A total of 7 flavonoids (schaftoside, luteolin-7-O-glucuronide, luteolin-7-O-glucoside, apigenin-7-O-glucuronide, luteolin, apigenin, and chrysin) and 1 coumarin (esculetin), were found to permeate and/or retained by intact or broken skin. Among them, the flavonoids were more permeable through intact/broken skin and exhibited stronger binding affinities for targets related to the inflammatory and proliferative phases of wound healing. This study suggests that the flavonoids in Cayratia japonica ointment are most likely the main active components and are crucial at the inflammatory and proliferative phases of wound healing.

Abstract
Ulcerative colitis is a lifelong inflammatory disease affecting the rectum and colon to a variable extent. In 2023, the prevalence of ulcerative colitis was estimated to be 5 million cases around the world, and the incidence is increasing worldwide. Ulcerative colitis is thought to occur in people with a genetic predisposition following environmental exposures; gut epithelial barrier defects, the microbiota, and a dysregulated immune response are strongly implicated. Patients usually present with bloody diarrhoea, and the diagnosis is based on a combination of clinical, biological, endoscopic, and histological findings. The aim of medical management is, first, to induce a rapid clinical response and normalise biomarkers and, second, to maintain clinical remission and reach endoscopic normalisation to prevent long-term disability. Treatments for inducing remission include 5-aminosalicylic acid drugs and corticosteroids. Maintenance treatments include 5-aminosalicylic acid drugs, thiopurines, biologics (eg, anti-cytokines and anti-integrins), and small molecules (Janus kinase inhibitors and sphingosine-1-phosphate receptor modulators). Although the therapeutic options are expanding, 10-20% of patients still require proctocolectomy for medically refractory disease. The keys to breaking through this therapeutic ceiling might be the combination of therapeutics with precision and personalised medicine.

Abstract
BACKGROUND Previous observational studies have found that fistulas are common in Crohn's disease (CD) and less common in ulcerative colitis (UC). However, some patients have a fistula before diagnosis. Based on retrospective analysis, it was not possible to determine whether there was a bi-directional causal relationship between inflammatory bowel disease (IBD) and fistulas. METHODS Data were extracted from the open GWAS database; 25,042 cases and 34,915 controls were included for IBD, and 6926 cases and 30,228 controls were included for fistula. Two-sample Mendelian randomization and multivariable Mendelian randomization were used in combination to determine the causal relationship between IBD and fistula. RESULTS Forward MR showed that IBD increased the risk of colonic or urogenital fistula (FISTULA) (OR: 1.09, 95% CI: 1.05 to 1.13, p = 1.22 × 10-6), mainly associated with fissure and fistula of the anal and rectal regions (FISSANAL) (OR:1.10, 95% CI:1.06 to 1.14, p = 6.12 × 10-8), but not with fistulas involving the female genital tract (FEMGENFISTUL) (OR:0.97, 95% CI: 0.85 to 1.11, p = 0.669). Furthermore, both UC and CD increased the risk of FISTULA. However, after adjusting by MVMR, only CD increased the risk of FISTULA (OR: 1.06, 95% CI: 1.02 to 1.11, p = 0.004), and UC did not increase the risk of FISTULA (OR: 1.01, 95% CI: 0.95 to 1.06, p = 0.838). Reverse MR showed that fistulas did not increase the risk of IBD. CONCLUSION Our study confirms it is CD, rather than UC, that casually leads to an increased risk of fistula, but fistulas do not increase the risk of IBD.

Abstract
Surgery is the most important treatment for perianal abscesses. However, the gut microbiota of patients with perianal abscess and the effects of perianal abscess on the gut microbiota after surgery are unknown. In this study, significant changes in interleukin 6 and tumor necrosis factor-α in the blood of healthy subjects, patients with perianal abscesses, and patients after perianal abscess surgery were identified. 16S rRNA gene sequencing technology was used to detect the changes in the gut microbiota among 30 healthy individuals and 30 patients with perianal abscess before and after surgery. Venn diagrams and alpha diversity analyses indicated differences in the abundance and uniformity of gut microbiota between the healthy individuals and patients with perianal abscesses before and after surgery. Beta diversity analysis indicated that the grouping effects among the control, abscess, and surgery groups were good. The classification and compositional analysis showed significant differences in the gut microbiota between healthy individuals and patients with perianal abscesses before and after surgery. LEfSe analysis, random forest analysis, and ROC curve analysis showed that Klebsiella (AUC = 0.7467) and Bilophila (AUC = 0.72) could be potential biomarkers for the diagnosis of perianal abscess. The functional prediction results showed that the differential microbiota is significantly enriched in the pathways related to nutrition and drug metabolism. This study may have important implications for the clinical management and prognostic assessment of patients with perianal abscesses.

Abstract
Interventional inflammatory bowel disease (IBD) or endoscopic therapy for IBD or IBD surgery-associated complications has emerged as a main treatment modality bridging medical and surgical treatment. It delivers therapy more definitive than medical therapy and less invasive than surgical treatment. The main applications of interventional IBD are strictures, fistulas, abscesses, bleeding, foreign bodies, postoperative complications, and colitis-associated neoplasia. The major endoscopic treatment modalities are balloon dilation, stricturotomy, strictureplasty, fistulotomy, sinusotomy, septectomy, banding ligation, incision and drainage, polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection.

Abstract
BACKGROUND AND AIM Ulcerative colitis (UC) is usually detected by clinical symptoms, such as bleeding and diarrhea; however, it is rather difficult to assess during asymptomatic clinical remission (CR). Hence, there is a need for a biomarker that can reliably detect UC during remission. We previously reported on the utility of the prostaglandin E-major urinary metabolite (PGE-MUM) as a biomarker reflecting UC activity. In this study, we evaluated the effectiveness of the PGE-MUM in the diagnosis of endoscopic, histological, and histo-endoscopic mucosal remission of UC, comparing with fecal tests. METHODS This prospective study was conducted at the Jikei University Hospital between August 2017 and January 2021. Patients with UC in CR scheduled to undergo colonoscopy were included. The association between the PGE-MUM with endoscopic remission (ER), histological remission (HR), and complete mucosal healing (CMH, defined as histo-endoscopic remission) was analyzed. We also compared the area under the curve (AUC) for the receiver operating characteristic curves between PGE-MUM, fecal calprotectin (FC), and fecal immunochemical test (FIT). RESULTS In total, 128 patients were analyzed. PGE-MUM differed significantly in ER versus non-ER (14.5 vs 16.7, P = 0.028), HR versus non-HR (14.2 vs 17.4, P = 0.004), and CMH versus non-CMH (14.3 vs 16.7, P = 0.021). There were no significant differences between the AUCs for PGE-MUM, FC, and FIT for ER, HR, or CMH. CONCLUSIONS The PGE-MUM can determine CMH in UC even during CR, regardless of the disease phenotype, indicating its clinical benefit for non-invasive monitoring.

Abstract
PURPOSE The aim of this study was to explore potential correlation of the MR imaging features and clinical characteristics with formation of perianal abscess in children with Crohn's perianal fistulas (CPF). METHODS From 2010 to 2020, pediatric patients with CPF diagnosis on their first pelvic MRI were identified retrospectively. All patients were divided into two groups based on the presence or absence of perianal abscess. Baseline clinical and MRI characteristics were recorded for each patient. All the statistical calculations were performed using R (version 3.6.3). RESULTS A total of 60 patients [F:M 17:43, median age 14 years (IQR 10-15), ranging 3-18 years] were included in this study. Forty-four abscesses were identified in 36/60 children (mean volume 3 ± 8.6 ml, median 0.3 ml). In 24/60 patients with perianal disease, no abscess was detected on the MRI. Ten patients (28%) showed perianal abscess on pelvic MRI at the initial diagnosis. The rate of active disease on colonoscopy (visible ulcerations/aphthous ulcers) was similar in both groups (95% vs. 94%). With regards to disease location, the majority of patients (40/60, 66.6%) in both groups had ileocolonic CD. All patients without abscess had a single perianal fistula (n = 24; 3 simple and 21 complex fistulae), however, patients with perianal abscess tended to have >1 fistulous tracts (n = 50 fistulas; all complex, 27 single, 10 double and 1 triple). Intersphincteric fistula was the most common fistula type in both groups (79% and 66%, p = 0.1). The total length of fistula (3.8 ± 1.7 vs. 2.8 ± 0.8 cm, p = 0.006) and presence of multiple external openings (n = 25 vs. 7, p = 0.019) were significantly higher in patients with abscesses, and fistula length >3.3 cm showed 80% specificity and 83% PPV for the presence of perianal abscess. Fistulas were symptomatic (pain, bleeding or drainage) at similar rates in both groups (68% and 70%, p = 0.1). CONCLUSION Pediatric patients with CPF who develop perianal abscess have a distinct imaging phenotype defined by longer fistula length (>3.3 cm), multiple skin openings and multiple fistulous tracts (≥2) on MRI. Patients who have these features but does not have an abscess on imaging may merit more aggressive treatment (and close monitoring) to prevent the development of an abscess.

Abstract
BACKGROUND Ileoanal pouch anastomosis is the surgical treatment of choice for patients with intractable ulcerative colitis. Perianal disease is a feature that is often present in Crohn's disease and infrequently in ulcerative colitis. OBJECTIVE The aim of this study is to identify the incidence and factors associated with the development of postoperative perianal fistula in patients undergoing ileoanal pouch anastomosis for ulcerative colitis. DESIGN A prospectively collected database at the time of surgery with subsequent follow-up was utilized. SETTING The study was conducted at a high-volume single institution. PATIENTS We studied a series of 475 consecutive patients with preoperative diagnosis of ulcerative colitis who underwent ileoanal pouch anastomosis. MAIN OUTCOME MEASURES The incidence of postoperative perianal fistula and the factors correlating with its development were primary outcome measures of the study. RESULTS The overall number of patients developing perianal fistulas was 44 of 475 (9%). Eleven patients with perianal fistula (25%) required return to ileostomy, of which 7 had pouch excision. Patients who developed a postoperative perianal fistula had a younger age at the onset of disease, had a lower age at index surgery, and were more likely to be subsequently classified as indeterminate colitis or Crohn's disease. Patients developing perianal fistulas were also more likely to develop partial dehiscence or stricture of the ileoanal anastomosis. LIMITATIONS This study spans nearly 40 years during which the surgical procedure evolved. CONCLUSIONS Young age at the onset of disease, lower age at surgery, and postoperative diagnosis of Crohn's disease and indeterminate colitis were the factors correlating with perianal fistulas. Delayed healing of the ileoanal anastomosis with partial separation and/or stricture also correlated with the onset of perianal fistulas. The severity of rectal inflammation at the time of surgery or the presence of stapled versus handsewn anastomosis did not correlate with the development of perianal fistulas.

FSTULA PERIANAL POSTERIOR A RESERVORIO ILEOANAL EN PACIENTES CON COLITIS ULCERATIVA UNA REVISIN DE PACIENTES OPERADOS EN UN CENTRO PRINCIPAL DE EII ANTECEDENTES:El reservorio ileoanal es el tratamiento quirúrgico de elección para los pacientes con colitis ulcerativa intratable. La enfermedad perianal es una característica que a menudo está presente en la enfermedad de Crohn y con poca frecuencia en la colitis ulcerativa.OBJETIVO:El objetivo del estudio es identificar la incidencia y los factores asociados con el desarrollo de fístula perianal posoperatoria en pacientes sometidos a reservorio ileoanal por colitis ulcerativa.DISEÑO:Base de datos recopilada prospectivamente en el momento de la cirugía con seguimiento subsecuente.ENTORNO CLÍNICO:El estudio se llevó a cabo en una única institución de gran volumen.PACIENTES:Estudiamos una serie de 475 pacientes consecutivos con diagnóstico preoperatorio de colitis ulcerativa a los que se les realizó reservorio ileoanal.PRINCIPALES MEDIDAS DE VALORACIÓN:La incidencia de fístula perianal posoperatoria y los factores que se correlacionan con su desarrollo fueron las principales medidas de resultado del estudio.RESULTADOS:El número total de pacientes que desarrollaron fístulas perianales fue 44 de 475 (9%). Once pacientes con fístula perianal (25%) requirieron volver a la ileostomía, de los cuales 7 tuvieron resección del reservorio. Los pacientes que desarrollaron fístula perianal posoperatoria tenían edad más temprana al inicio de la enfermedad, menor edad en el momento de la cirugía inicial y tenían más probabilidades de ser clasificados posteriormente como colitis indeterminada o enfermedad de Crohn. Los pacientes que desarrollaron fístulas perianales también fueron más propensos a desarrollar dehiscencia parcial o estenosis de la anastomosis ileoanal.LIMITACIONES:Este estudio abarca casi 40 años durante los cuales ha evolucionado el procedimiento quirúrgico.CONCLUSIONES:Edad temprana al inicio de la enfermedad, menor edad al momento de la cirugía, diagnóstico postoperatorio de enfermedad de Crohn y colitis indeterminada fueron los factores que se correlacionaron con las fístulas perianales. El retraso en la cicatrización de la anastomosis ileoanal con separación parcial y/o estenosis también se correlacionó con la aparición de fístulas perianales. La gravedad de la inflamación rectal en el momento de la cirugía o la presencia de anastomosis con grapas versus anastomosis manual no se correlacionó con el desarrollo de fístulas perianales.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is increasingly diagnosed in South Asia. This survey by the Tamil Nadu Chapter of the Indian Society of Gastroenterology (TNISG) documents the demography, clinical profile, and therapeutic practices related to IBD in Tamil Nadu. METHODS TNISG members from 32 institutions completed an online cross-sectional questionnaire on IBD patients from March 2020 to January 2021. RESULTS Of 1295 adult IBD patients, 654 had Crohn's disease (CD), 499 ulcerative colitis (UC), and 42 IBD-unclassified (IBD-U). CD and UC showed a unimodal age distribution. A total of 55% were graduates or postgraduates. A positive family history was noted in 30, other risk factors were uncommon. In CD, the pattern of involvement was ileocolonic (42.8%), ileal (34.7%), colonic (18.9%), and upper gastrointestinal (3.5%); while in UC, disease was characterized as extensive (44.9%), left-sided (41.7%), or proctitis (13.4%). Perineal disease, perianal fistulae, and bowel obstruction were noted in 4.3, 14.0, and 23.5%, respectively, of CD. The most widely used drugs were mesalamine, azathioprine, and corticosteroids. Surgery was undertaken in 141 patients with CD and 23 patients with UC. Of the 138 patients with pediatric IBD (≤16 years), 23 were characterized as very early onset IBD (VEO-IBD), 27 as early-onset, and 88 as adolescent IBD. VEO-IBD were more likely to have a positive family history of IBD and were more likely to have perineal disease and to have the IBD-U phenotype. Among pediatric IBD patients, corticosteroids, mesalamine, and azathioprine were the most commonly used medications, while 25 pediatric patients received biologics. CONCLUSION This study provides important information on demography, clinical profile, and treatment practices of IBD in India.

Abstract
AIM Excisional haemorrhoidectomy in patients with ulcerative colitis (UC), especially those undergoing an ileal pouch-anal anastomosis (IPAA), remains controversial. The aim of our study was to determine the safety of excisional haemorrhoidectomy in UC patients with and without an IPAA. METHOD A retrospective review of all adult UC patients undergoing excisional haemorrhoidectomy between 1 January 1995 and 1 January 2019 at a tertiary inflammatory bowel disease referral centre was performed. Data collected included patient demographics, clinical characteristics of UC, prior surgical intervention for UC (colectomy, IPAA) and complications after haemorrhoidectomy. RESULTS Forty-one adult patients [50% male; median age 52 (range 25-79) years] with UC underwent excisional haemorrhoidectomy between 1 January 1995 and 1 January 2019. The majority (n = 23) had not previously undergone surgery for UC. However, eight had already undergone construction of an IPAA at the time of haemorrhoidectomy, seven had IPAA at the time of haemorrhoidectomy and three had an IPAA constructed subsequent to haemorrhoidectomy. Two (4.9%) patients need to go back to theatre for postoperative bleeding. There were no further 30-day complications or long-term nonhealing of the surgical site. There were no pouch complications in those who had haemorrhoidectomy at the time of IPAA construction or in the presence of an IPAA. CONCLUSION Our data suggest that excisional haemorrhoidectomy may be performed safely in carefully selected UC patients with symptomatic haemorrhoids with or without IPAA and even at the time of IPAA construction.

Hemorrhoidectomy and Excision of Skin Tags in IBD: Harbinger of Doom or Simply a Disease Running Its Course? Dis Colon Rectum 2019; 62:1505-1511.

Abstract
BACKGROUND Controversy in performing hemorrhoidectomy and anal skin tag excision in patients with IBD stems from dated reports of nonhealing wounds resulting in proctectomy. OBJECTIVE This study aimed to determine the safety of interventional management of hemorrhoids or anal skin tags in patients with Crohn's disease or ulcerative colitis. DESIGN This study is a retrospective review of patient records from 2000 to 2017. SETTING The patient records were retrieved from a multistate health system. PATIENTS Adult patients with IBD undergoing interventional management of hemorrhoids or skin tags were included. MAIN OUTCOME MEASURE The primary outcome measured was the long-term requirement of proctectomy. RESULTS Ninety-seven patients (n = 49 Crohn's disease, 48 ulcerative colitis) underwent interventional management of hemorrhoids or anal skin tags (n =35 rubber band ligation, 27 anal skin tag excision, 21 hemorrhoidectomy, 14 excision/incision of thrombosed hemorrhoid). Thirty-day complications were observed in 5 patients (n = 4 urinary retention, 1 perianal abscess). Five patients with Crohn's disease eventually required proctectomy at a median of 7 years after skin tag excision (range, 6 months to 10 years), but none were secondary to impaired wound healing. Two patients with ulcerative colitis who had previously undergone IPAA were subsequently diagnosed with Crohn's disease of the pouch after skin tag excision. No other long-term complications were seen in patients with ulcerative colitis. LIMITATIONS The study's retrospective design does not allow identification of patients with IBD who underwent only medical management of their hemorrhoids. There is also selection bias in which patients were selected for interventional management of their disease. CONCLUSIONS The requirement for proctectomy after hemorrhoidectomy/skin tag excision appears to be secondary to the natural disease course of perianal Crohn's disease rather than perianal intervention. Selective hemorrhoidectomy and skin tag excision in patients with well-controlled luminal disease should be considered. See Video Abstract at http://links.lww.com/DCR/B55.

Cinco pacientes con enfermedad de Crohn requirieron proctectomía en una media de 7 años después de la excisión de los plicomas ano-cutáneos (rango, 6 meses a 10 años), pero ninguno fue secundario a la mala cicatrización de la herida. Dos pacientes con colitis ulcerosa que previamente se habían sometido a una anastomosis colo-anal protegia por ilestomía fueron diagnosticados posteriormente con enfermedad de Crohn localizada en la ostomía después de la excisión de plicomas ano-cutáneos. No se observaron complicaciones a largo plazo en pacientes con colitis ulcerosa.El diseño retrospectivo del estudio no permite la identificación de pacientes con enfermedad inflamatoria intestinal que se sometieron únicamente al tratamiento médico de las hemorroides. También existe un sesgo de selección de pacientes escogidos para tratamiento instrumental de la enfermedad hemorroidaria.El requisito de proctectomía después de la hemorroidectomía / excisión de plicomas anocutáneos parece ser secundario al curso de la enfermedad natural de la enfermedad de Crohn perianal en el sitio de la intervención perianal. Se debe considerar la hemorroidectomía selectiva y la excisión de plicomas ano-cutáneos solo en pacientes con enfermedad endoluminal controlada.

Abstract
Anal fistula, or fistula-in-ano, is a condition involving the anal region that is common yet debilitating. Surgery is the mainstay of treatment for an anal fistula and the chances of recurrence are quite high even after corrective surgical procedures. The risk factors for recurrence can be broadly classified into four categories: 1) risk factors related to the fundamental anatomy of the fistula and presence of comorbidities, 2) lack of proper preoperative assessment of the fistula, which includes failure to recognize the internal opening and overall structure of the fistula and not supplementing the proctologic examination with sufficient imaging, 3) intraoperative loopholes that include improper procedure selection, inexperience of the surgeon, and failure to get rid of the entire tract along with its ramifications, and 4) lack of proper postoperative care in the early and late periods following the surgery. The aim of this paper, therefore, is to highlight the factors that could increase the risk of recurrence in different types of anal fistulae. Once surgeons know these risk factors, they can anticipate any complication and detect recurrence early.
