Is religiosity/spirituality in patients with Crohn's disease important to their quality of life?

The authors aim to study Religiosity/Spirituality (R/S) and Quality of Life (QoL) in patients with Crohn's disease and their correlation with the disease phenotypes. METHODS: Prospective cross-sectional cohort study with 151 consecutive patients enrolled from March 2021 to October 2021 at the Colorectal IBD Outpatient of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). Sociodemographic, Religiosity/Spirituality (Duke University Religion Index - Durel) questionnaires and QoL (Inflammatory Bowel Disease Questionnaire - Short IBDQ-S) were applied. When necessary, qualitative variables were evaluated using the chi-square or Fisher's exact test. The Mann-Whitney and Kruskall-Wallis tests were used to analyze quantitative variables and compare more than two groups, both non-parametric statistical techniques. RESULTS: The most frequent location was Ileocolonic followed by Ileal and colonic (41.1 %, 27.2 %, and 25.2 %); only 6.6 % of subjects had a perianal presentation. Inflammatory, stenosing, and penetrating behaviors showed 36.4 %, 19.1 %, and 44.4 % respectively. The majority of the population is Catholic, Evangelical, or Spiritualist (92.4 %). QoL score showed no significant difference in the phenotypes. The scores for DUREL domains were 61.4 % for organizational religiosity, 75 % for non-organizational religiosity, 98.6 %, 93.6 % and 89.3 % for intrinsic spirituality, with high results in all disease phenotypes. CONCLUSIONS: The studied population presented homogeneous sociodemographic results and high religious and spiritual activity. R/S in a positive context were not associated with better QoL or phenotype. R/S is present in the patients' lives and could be seen as an important tool for adherence to treatment and the professional relationship between doctor and patient. The homogeneity of the sample difficult for an appropriate evaluation, which leads us to suggest new studies with more heterogeneous groups.

RISK FACTORS FOR EARLY POSTOPERATIVE COMPLICATIONS IN ACUTE COLITIS IN THE ERA OF BIOLOGIC THERAPY.

BACKGROUND: Despite major advances in the clinical treatment of inflammatory bowel disease, some patients still present with acute colitis and require emergency surgery. AIMS: To evaluate the risk factors for early postoperative complications in patients undergoing surgery for acute colitis in the era of biologic therapy. METHODS: Patients with inflammatory bowel disease admitted for acute colitis who underwent total colectomy at a single tertiary hospital from 2012 to 2022 were evaluated. Postoperative complications were graded according to Clavien-Dindo classification (CDC). Patients with more severe complications (CDC≥2) were compared with those with less severe complications (CDC<2). RESULTS: A total of 46 patients underwent surgery. The indications were: failure of clinical treatment (n=34), patients' or surgeon's preference (n=5), hemorrhage (n=3), toxic megacolon (n=2), and bowel perforation (n=2). There were eight reoperations, 60.9% of postoperative complications classified as CDC≥2, and three deaths. In univariate analyses, preoperative antibiotics use, ulcerative colitis diagnosis, lower albumin levels at admission, and preoperative hospital stay longer than seven days were associated with more severe postoperative complications. CONCLUSIONS: Emergency surgery for acute colitis was associated with a high incidence of postoperative complications. Preoperative use of antibiotics, ulcerative colitis, lower albumin levels at admission, and delaying surgery for more than seven days were associated with more severe early postoperative complications. The use of biologics was not associated with worse outcomes.

Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV in the anorectal fistula tract. A comparative study.

BACKGROUND & AIMS: Perianal fistulizing Crohn's disease is the main risk factor for anal cancer in patients with inflammatory bowel disease. Whether this occurs due to a higher frequency of human papillomavirus remains unclear. The authors aimed to evaluate the prevalence of HPV and high-risk HPV in patients with perianal Crohn's disease, compared with a control group. METHODS: The authors conducted a two-center cross-sectional study in which perianal fistulizing Crohn's disease patients were matched for age and sex with patients with anorectal fistula without Crohn's disease. Biopsy specimens were obtained from fistulous tracts during examination under anesthesia for both groups. The samples were sent for HPV detection and genotyping using the INNO-LiPA test. RESULTS: A total of 108 subjects (54 in each group) were recruited. The perianal fistulizing Crohn's disease group showed a statistically higher frequency of HPV in the fistulous tract than the control group (33.3% vs. 16.7%; p = 0.046). Separate analyses on high-risk types demonstrated that there was a numerically higher frequency of HPV in the perianal fistulizing Crohn's disease group. In multiple logistic regression, patients with perianal fistulizing Crohn's disease were found to have a chance of HPV 3.29 times higher than patients without Crohn's disease (OR = 3.29; 95% CI 1.20‒9.01), regardless of other variables. The types most frequently identified in the perianal fistulizing Crohn's disease group were HPV 11 (12.96%) and HPV 16 (9.26%). CONCLUSION: Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV than in patients with anorectal fistula without Crohn's disease.

Risk factors for early postoperative complications in acute colitis in the era of biologic therapy / Fatores de risco para complicações pós-operatórias precoces em colite aguda na era da terapia biológica

RESUMO RACIONAL: Apesar dos enormes avanços no tratamento das doenças inflamatórias intestinais (DII), alguns pacientes apresentam quadros de colite aguda refratária ao tratamento clínico, e necessitam de cirurgia de urgência. OBJETIVOS: Avaliar os fatores de risco associados com complicações pós-operatórias precoces nos pacientes com colite aguda submetidos a colectomia na era das terapias biológicas. MÉTODOS: Pacientes com DII admitidos com colite aguda grave submetidos a colectomia total em hospital terciário no período de 2012 a 2022 foram analisados. As complicações pós-operatórias foram graduadas de acordo com a classificação Clavien-Dindo (CCD). Pacientes com complicações mais graves (CCD≥2) foram comparados com os menos graves (CCD<2). RESULTADOS: Foram submetidos a cirurgia 46 pacientes. As indicações foram: falha do tratamento conservador (n=34), preferência do paciente ou do cirurgião (n=5), hemorragia (n=3), megacólon tóxico (n=2) e perfuração intestinal (n=2). Reoperação foi necessária em oito pacientes, 60,9% tiveram complicações classificadas como CCD≥2, e três pacientes foram a óbito. Análise univariada identificou que uso de antibióticos no pré-operatório, diagnóstico de colite ulcerativa, hipoalbuminemia na admissão e período de internação maior que sete dias foi associada à complicações pós-operatória mais graves. CONCLUSÕES: Pacientes com colite aguda submetidos a cirurgia de urgência apresentaram alta taxa de complicações pós-operatórias. Uso pré-operatório de antibióticos, diagnóstico de retocolite ulcerativa, hipoalbuminemia na admissão e retardo na operação por mais que sete dias, esteve associado a complicações pós-operatórias mais graves. Uso de biológicos não se associou a piores desfechos.

Case series of right colon diverticulitis in the west: a neglected disease?

Introduction: Right colon diverticulitis (RCD) is an uncommon condition in Western populations, but its incidence has increased over the last decades. Due to its rarity, many surgeons are unfamiliar with this disease, which is often mistakenly diagnosed as acute appendicitis. The lack of data about the diagnosis and management of RCD in Western populations makes it difficult to establish the optimal therapeutic strategy. Objective: To evaluate the outcomes of patients treated for acute RCD and to propose a therapeutic algorithm for the diagnosis and treatment. Methods: A retrospective analysis of the medical records of patients treated for acute RCD between 2008 and 2020 by a single experienced colorectal surgeon was performed. Results: In total, 12 patients were identified, 8 male and 4 female subjects, with a mean age of 49.6 years; 9 of these patients were of Western origin. The median follow-up time was of 49 months (range: 12 to 144 months). The most frequent symptoms were abdominal pain (100%) and fever (66%). Diagnostic errors in imaging exams occurred in four patients. A total of 6 patients were managed clinically, and the other 6 underwent surgical treatment with right colectomy (n = 5) and total colectomy (n = 1), 2 via laparoscopy and 4 through a laparotomy. The anatomopathological examination confirmed RCD in all operated patients. There was no incidental finding of neoplasia and there were no deaths during the study period. Conclusion: Uncomplicated RCD can be treated conservatively with a high success rate. Recurrent cases that impact quality of life or complicated forms of RCD should undergo surgical treatment, preferably through a right laparoscopic colectomy. The authors present a diagnostic and therapeutic algorithm to facilitate the diagnosis and to guide the management of this uncommon disease. (AU)

STAPLED HEMORRHOIDOPEXY: RESULTS, LATE COMPLICATIONS, AND DEGREE OF SATISFACTION AFTER 16 YEARS OF FOLLOW-UP.

BACKGROUND: Stapled hemorrhoidopexy has been widely used for the treatment of hemorrhoids, but concerns about complications and recurrences after prolonged follow-up are still under debate. AIMS: The aim of this study was to evaluate the very long-term results of the stapled hemorrhoidopexy technique. METHODS: Stapled hemorrhoidopexy was performed on 155 patients between 2000 and 2003, and the early results have already been published. In this study, we evaluated the same patients after a very long follow-up. Data were collected with regard to late complications, rate and timing of recurrences, and patients' degree of satisfaction. RESULTS: From a total of 155 patients, 98 patients were evaluated: 59 (60.2%) were interviewed by telephone and 39 (39.8%) were evaluated by outpatient consultation. The mean follow-up was 193 months (range: 184-231), 52 were female, 52 were grade III hemorrhoids, and 46 were grade IV. Recurrence was higher in grade IV (26.1%) than in grade III (7.7%) (p=0.014). Recurrence after prolonged follow-up was seen in 16 patients (16.3%) and 11 (11.2%) required reoperations. The complications were skin tags (3.1%), anal sub-stenosis (2.1%), and fecal incontinence (2.1%). After a prolonged follow-up, 82.5% of patients were either very satisfied or satisfied with the surgery. CONCLUSIONS: Stapled hemorrhoidopexy is a safe and effective treatment for hemorrhoidal disease grades III and IV. Recurrence is higher for grade IV hemorrhoids and may occur up to 9 years of follow-up. Reoperations were infrequent and there is a high patient's degree of satisfaction associated with this technique.

Fournier's Gangrene During Pregnancy in a Patient with Crohn's Disease.

BACKGROUND Fournier's gangrene (FG) is a rapidly progressive necrotizing infection of the perineum. Risk factors include male sex and immunosuppression. Inflammatory bowel disease and pregnancy may alter immune response by complex mechanisms but have rarely been associated with necrotizing infections of the perineum. To the best of our knowledge, only 5 cases of FG in association with IBD have been reported in the literature, and none of them occurred during pregnancy. CASE REPORT We report the case of a young woman with long-standing Crohn's disease in clinical remission with Infliximab monotherapy who developed FG in the third trimester of pregnancy. A cesarean section was undertaken at 35 weeks due to fetal distress, followed by debridement, diverting stoma, and vacuum-assisted therapy. The perineal defect was closed following 4 debridements and vacuum-therapy exchanges with a unilateral medial thigh advancement flap, and a draining seton was placed in the suprasphincteric fistula. The patient was discharged after 28 days and her recovery was unremarkable. The neonate also recovered well. CONCLUSIONS The treatment of FG is multidisciplinary and includes early debridement and intestinal diversion. Perianal pain should not be disregarded, as it may be the initial symptom of severe perianal sepsis in the immunosuppressed. To the best of our knowledge, this is the first case report of FG during pregnancy in a patient with Crohn's disease.

Anorectal Mucosal Melanoma: A Case Report and Literature Review.

BACKGROUND Anorectal mucosal melanoma (AMM) is a rare and aggressive neoplasm, with a 5-year survival rate of 10%. Due to its rarity and nonspecific symptoms, the diagnosis is often made late. Surgical resection remains the criterion standard for treatment of anorectal melanoma. CASE REPORT We present the case of an 81-year-old woman presenting with hematochezia, anal secretion, tenesmus, difficulty in defecation, and perianal pain. On physical examination, there was a prolapse of a 5-cm melanocytic nodule in the anal canal, hard on palpation. Biopsy confirmed anorectal melanoma. Staging revealed anal and metastatic disease, with adrenal, lymphatic, and hepatic involvement. As the patient continued to have bleeding, severe pain, and difficulty in defecation, she was submitted to a wide local excision. At 5-month follow-up, the anal lesion had relapsed, and the patient died 10 months after the procedure. CONCLUSIONS AMM is a rare and extremely aggressive tumor. Symptoms are nonspecific but early diagnosis should be pursued to allow curative treatment. Surgical resection with free margins is the goal of surgical treatment. New therapies are being studied, including immunotherapy, which can improve the dismal prognosis of this rare disease.

A NEW APPROACH FOR HEMORRHOID DISEASE: SELECTIVE DEARTERIALIZATION AND MUCOPEXY WITHOUT DOPPLER GUIDANCE.

BACKGROUND: The surgical procedure: three dearterializations and three mucopexies.Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. AIM: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. METHODS: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. RESULTS: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. CONCLUSION: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.

Abdominal Surgery in Crohn's Disease: Risk Factors for Complications.

INTRODUCTION: Abdominal surgery in patients with Crohn's disease (CD) is challenging, especially in the biologic era. The aim of this study was to evaluate factors associated with increased risk for postoperative complications in CD. METHODS: A retrospective study was conducted with consecutive patients who underwent abdominal surgery for CD from January 2012 to January 2018. RESULTS: Of 103 patients, 32% had postoperative complications. Gender, age, disease location and phenotype, hemoglobin and albumin levels, previous abdominal surgery, and preoperative optimization did not differ between the groups with or without complications. Thirty-five percent of the patients were under anti-TNF therapy, and this medication was not associated with increased risk for postoperative complications. Time since the onset of the disease was significantly higher in patients with complications (12.9 vs. 9.4, p = 0.04). In multivariate analysis, creation of ostomy and urgent surgery were the only variables independently associated with increased risk for complications (OR 3.2, 95% CI 1.12-9.46 and OR 2.94, 95% CI 0.98-9.09, respectively). CONCLUSION: Urgent surgery for CD should preferably be performed in specialized centers, and creation of stoma is not necessarily associated with lower rate of postoperative complications but rather less severe complications.

Coexistence of Takayasu's Arteritis in Patients with Inflammatory Bowel Diseases.

BACKGROUND: Takayasu's arteritis (TA) and inflammatory bowel disease (IBD) are chronic inflammatory granulomatous disorders that have rarely been concomitantly reported in case reports and small case series. OBJECTIVE: We report a series of seven cases of TA and IBD association in two referral centers with a comprehensive review of literature. METHODS: We analyzed retrospectively the electronic medical charts of TA-IBD patients at the University Hospital of São Paulo, Brazil, and at the Sheba Medical Center at Tel Aviv University, Israel. RESULTS: Overall, five patients had Crohn's disease (DC) and two had ulcerative colitis (UC), and they were mostly female and non-Asian. All patients developed IBD first and, subsequently, TA. Two underwent colectomy and one ileocecectomy due to IBD activity, while three required cardiovascular surgery due to TA activity. Most patients are currently in clinical remission of both diseases with conventional drug treatment. CONCLUSION: Although the coexistence of TA and IBD is uncommon, both seem to be strongly associated through pathophysiological pathways.

The novel BPRST classification for hemorrhoidal disease: A cohort study and an algorithm for treatment.

BACKGROUND: The classification for HD was developed by Goligher in 1980 and does not contemplate important aspects of this disease, which limits its use in guiding treatment. The aim of this study if to apply in clinical practice the new classification for hemorrhoids named BPRST (bleeding, prolapse, reduction, skin tags, thrombosis), to compare it with the original classification proposed by Goligher and to propose an algorithm for treatment. MATERIALS AND METHODS: This is a prospective study conducted at the University of São Paulo's teaching hospital and Hospital 9 de Julho. Patients with HD treated from March 2011 to July 2013 were included. Patients were classified according to BPRST and Goligher classifications and treated according to personal experience and most updated guidelines. The association between both classifications and the treatment adopted was compared and an algorithm for treatment was developed. RESULTS: 229 patients were included in this study and 28 patients were lost due to follow-up. According to Goligher, 29, 61, 85 and 26 were classified as grades I, II, III and IV, respectively. According to the BPRST, 23 were classified as stage I, 95 as stage II and 83 as stage III. Six patients classified as Goligher I were reclassified as BPRST stage III and required conventional hemorrhoidectomy, either due to thrombosis (n = 4) or intolerable skin tags (n = 2). The BPRST classification was more closely associated with the type of treatment employed and had few outliers than Goligher (p < 0.001). CONCLUSION: There are limitations to the use of Goligher's classification in clinical practice. The novel BPRST classification includes important aspects of HD that should be considered when deciding the best treatment option. Our algorithm for treatment contemplates the most commonly used techniques and can help to guide the treatment of this complex disease.

A new approach for hemorrhoid disease: selective dearterialization and mucopexy without doppler guidance / Uma nova opção para o tratamento da doença hemorroidária: desarterialização e mucopexia seletiva sem o ultrassom doppler

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.

RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.

CRITICAL ANALYSIS OF ANTI-TNF USE IN THE ERA OF NEW BIOLOGICAL AGENTS IN INFLAMMATORY BOWEL DISEASE.

BACKGROUND: Inflammatory bowel diseases (IBD), both Crohn's disease and ulcerative colitis, are chronic immune-mediated diseases that present a relapsing and remitting course and requires long-term treatment. Anti-tumor necrosis factor (anti-TNF) therapy has changed the management of the disease by reducing the need for hospitalizations, surgeries and improving patient´s quality of life. OBJECTIVE: The aim of this review is to discuss the role of anti-TNF agents in IBD, highlighting the situations where its use as first-line therapy would be appropriate. METHODS: Narrative review summarizing the best available evidence on the topic based on searches in databases such as MedLine and PubMed up to April 2020 using the following keywords: "inflammatory bowel disease'', "anti-TNF agents" and ''biologic therapy''. CONCLUSION: Biological therapy remains the cornerstone in the treatment of IBD. In the absence of head-to-head comparisons, the choice of the biological agent may be challenging and should take into account several variables. Anti-TNF agents should be considered as first line therapy in specific scenarios such as acute severe ulcerative colitis, fistulizing Crohn's disease and extra-intestinal manifestations of IBD, given the strong body of evidence supporting its efficacy and safety in these situations.

Análise crítica do uso dos anti-TNF na era dos novos agentes biológicos na doença inflamatória intestinal / Critical analysis of anti-tnf use in the era of new biological agents in inflammatory bowel disease

RESUMO CONTEXTO: As doenças inflamatórias intestinais (DII), tanto a doença de Crohn (DC) como a retocolite ulcerativa (RCU), são doenças crônicas imunomediadas que se apresentam com períodos de surto e remissão e requerem terapia a longo prazo. A terapia com anti-fator de necrose tumoral (anti-TNF) tem mudado o manejo da doença reduzindo a necessidade de hospitalizações, cirurgias e melhorando a qualidade de vida dos pacientes. OBJETIVO: O objetivo do presente trabalho é apresentar uma revisão sobre a importância dos agentes anti-TNF no contexto da DII, levando em consideração situações em que essas drogas são usadas como terapia de primeira linha. MÉTODOS: Revisão narrativa baseada nas melhores evidências disponíveis na literatura através de buscas feitas nas bases de dados MedLine e PubMed até abril de 2020, utilizando as seguintes palavras chaves: "doença inflamatória intestinal'', "agentes anti-TNF" e "terapia biológica". CONCLUSÃO: A terapia biológica permanece sendo fundamental no tratamento da DII. Na ausência de estudos "head-to-head'' comparando os biológicos entre si, a escolha do agente biológico pode ser um desafio na prática clínica e múltiplas variáveis devem ser levadas em consideração. Os agentes anti-TNF devem ser considerados terapia de primeira linha em situações específicas como na colite ulcerativa aguda grave, na doença de Crohn fistulizante e nas manifestações extra-intestinais da doença inflamatória intestinal, uma vez que há evidências científicas robustas que sustentam a sua eficácia e segurança nessas situações.
