Characterization of obstructive defecation from a structural and a functional perspective.

BACKGROUND/AIMS: Defecation disorders can occur as a consequence of functional or structural anorectal dysfunctions during voiding. The aims of this study is to assess the prevalence of structural (SDD) vs functional (FDD) defecation disorders among patients with clinical complaints of obstructive defecation (OD) and their relationship with patients' expulsive capacity. PATIENTS AND METHODS: Retrospective study of 588 patients with OD studied between 2012 and 2020 with evacuation defecography (ED), and anorectal manometry (ARM) in a subgroup of 294. RESULTS: 90.3% patients were women, age was 58.5±12.4 years. Most (83.7%) had SDD (43.7% rectocele, 45.3% prolapse, 19.3% enterocele, and 8.5% megarectum), all SDD being more prevalent in women except for megarectum. Functional assessments showed: (a) absence of rectification of anorectal angle in 51% of patients and poor pelvic descent in 31.6% at ED and (b) dyssynergic defecation in 89.9%, hypertonic IAS in 44%, and 33.3% rectal hyposensitivity, at ARM. Overall, 46.4% of patients were categorized as pure SDD, 37.3% a combination of SDD+FDD, and 16.3% as having pure FDD. Rectal emptying was impaired in 66.2% of SDD, 71.3% of FDD and in 78% of patients with both (p=0.017). CONCLUSIONS: There was a high prevalence of SDD in middle-aged women with complaints of OD. Incomplete rectal emptying was more prevalent in FDD than in SDD although FDD and SDD frequently coexist. We recommend a stepwise therapeutic approach always starting with therapy directed to improve FDD and relaxation of striated pelvic floor muscles.

Catheter-directed hemorrhoidal embolization for rectal bleeding due to hemorrhoids (Goligher grade I-III): prospective outcomes from a Spanish emborrhoid registry.

OBJECTIVES: To evaluate the safety and efficacy of catheter-directed hemorrhoidal embolization (CDHE) by microcoil embolization for rectal bleeding due to hemorrhoids classified as Goligher grade I-III. METHODS: Eighty patients (62.5% males) with a mean age of 48 ± 9 years were recruited prospectively. All patients had symptomatic bleeding hemorrhoids. All patients were classified according to Goligher classification: grade I (13.7%), grade II (71.1%), grade III (15%), and no grade IV were recruited in this study. In all cases, microcoils were used to embolize the superior rectal artery(SRA), and microspheres if recurrence of bleeding occurred. Follow-up evaluation (1, 3, 6, and 12 months) included clinical examination and anoscopy. A questionnaire was conducted to determine improvement regarding bleeding, quality of life before, and the degree of patient satisfaction of each participant. RESULTS: Technical success was achieved in 100% of the cases. Fifty-five (68.7%) participants had the absence of rectal bleeding after 12 months of embolization. VAS and QL improved 4 points and 1.5 respectively after embolization. A total of 25/80 (31.3%) had a recurrence in rectal bleeding. Seventeen (21.3%) patients underwent a second embolization, and four patients (5%) were treated with open hemorrhoidectomy. No major complications were observed. Sixteen participants had minor complications. Subjective post-treatment symptom and QL surveys showed significant differences from the baseline survey. Likewise, the degree of satisfaction in the telephone survey at 12 months revealed a high degree of patient satisfaction (8.3±1.1). CONCLUSIONS: The present study demonstrates that CDHE is a feasible, well-tolerated, ambulatory, anal sphincter-sparing procedure for the treatment of internal hemorrhoids. CLINICAL RELEVANCE STATEMENT: CDHE is a simple procedure, well tolerated and accepted by patients, that preserves the anal sphincter and presents few complications when metal devices or microspheres are used as embolic agents. KEY POINTS: • The technical success rate of CDHE, defined as the closure of all the SRA in their distal segment, was achieved 100% of all patients. However, a second embolization treatment was required since 21.25% of the patients experienced rectal bleeding. • Overall, CDHE's safety profile is acceptable. After the procedure and 1 year of follow-up, no significant complications were observed. • Encouraging clinical outcomes have demonstrated CDHE in individuals with hemorrhoids and mild prolapse Goligher grades I-III with persistent rectal bleeding.

State-of-the-art surgery for Crohn's disease: part III-perianal Crohn's disease.

PURPOSE: Diagnosis and treatment of perianal Crohn's disease is challenging and requires its own domain of therapy. Different types of perianal disease require a spectrum of treatment strategies. Treatment options range from conservative therapy, including immunosuppressives, biologics, or stem cell therapy, to surgical treatment with specific indications depending on the underlying lesion. This is part III of the series "state-of-the-art surgery for Crohn's disease," focusing on the management of perianal disease. We discuss the definition and diagnosis of perianal Crohn's disease, the treatment of perianal lesions, and specific surgical indications and techniques. RESULTS AND CONCLUSION: Pitfalls and complications play a substantial role in the treatment of perianal Crohn's disease, and surgical therapy may fail. Realistic treatment goals and an individual patient-oriented treatment approach are crucial in the treatment of perianal Crohn's disease.

Rectal Bezoar: A Rare Cause of Intestinal Obstruction.

Bezoars are conglomerates of undigested contents that accumulate in the gastrointestinal tract. They can have different compositions, such as fibers, seeds, vegetables (phytobezoars), hair (trichobezoars), and medication (pharmacobezoars). Bezoars are typically caused by an impaired grinding mechanism of the stomach or interdigestive migrating motor complex, but the composition of ingested material can also play a role in their formation. Gastric dysmotility, previous gastric surgery, and gastroparesis are some of the risk factors that can increase the likelihood of developing bezoars. While bezoars are usually asymptomatic and found in the stomach, they can sometimes migrate to the small intestine or colon and cause complications such as intestinal obstruction or perforation. Endoscopy is essential for diagnosis and etiology, and treatment depends on the composition, which can include chemical dissolution or surgical intervention. We present a case of an 86-year-old woman, who had a bezoar located in an unusual location (rectum), most likely due to migration. This condition led to symptoms of intermittent intestinal obstruction and rectal bleeding. However, due to anal stenosis, the patient was unable to expel the bezoar. Its removal was not possible through various endoscopic techniques. Therefore, it was removed via fragmentation, using an anoscope and forceps, due to its hard/stone-like consistency. This case highlights the importance of considering bezoars in the differential diagnosis of gastrointestinal bleeding and illustrates the importance of prompt diagnosis and appropriate techniques for the removal of bezoars.

Uso de stent en estenosis colorrectal benigna / Stent utilization in benign colorectal stenosis

Introducción. La estenosis colorrectal benigna hace referencia a una condición anatómica caracterizada por una disminución del diámetro de la luz intestinal distal a la válvula ileocecal, ocasionando una serie de signos y síntomas de tipo obstructivo. Es una entidad poco frecuente, secundaria en la gran mayoría de veces a la realización de anastomosis intestinales al nivel descrito. El objetivo de esta investigación fue determinar la utilidad del stentcolónico en estenosis secundaria a patología colorrectal no neoplásica. Métodos. Estudio descriptivo de una cohorte de pacientes que desarrolló estenosis colorrectal de origen benigna confirmada por colonoscopía, en 3 hospitales de alta complejidad de la ciudad de Medellín, Colombia, entre los años 2007 y 2021. Resultados. Se incluyeron 34 pacientes con diagnóstico de estenosis colorrectal de origen benigno, manejados con stents metálicos autoexpandibles. La mediana de seguimiento fue de 19 meses y se obtuvo éxito clínico en el 73,5 % de los casos. La tasa de complicación fue del 41,2 %, dada principalmente por reobstrucción y migración del stent, y en menor medida por perforación secundaria a la colocación del dispositivo. Conclusión. Los stents metálicos autoexpandibles representan una opción terapéutica en pacientes con obstrucción colorrectal, con altas tasas de mejoría clínica en pacientes con patología estenosante no maligna. Cuando la derivación por medio de estoma no es una opción, este tipo de dispositivos están asociados a altas tasas de éxito clínico y mejoría de la calidad de vida de los pacientes

Introduction. Benign colorectal stenosis refers to an anatomical condition characterized by a decrease in the diameter of the intestinal lumen distal to the ileocecal valve, which might cause a series of obstructive signs and symptoms. It is a rare entity, caused in the vast majority of cases due to intestinal anastomosis at the described level. The purpose of this study is to determine the performance of colonic stents in the management of non-malignant colorectal strictures. Methods. Descriptive study of a cohort of patients who developed a benign colorectal stenosis confirmed by colonoscopy in three high-complexity hospitals in the city of Medellín, Colombia, between 2007 and 2021. Results. Thirty-four patients diagnosed with benign colorectal stenosis managed with self-expanding metal stents were included in the study. Median follow-up was 19 months, obtaining clinical success in 73.5% of cases, with a complication rate of 41.2%, mainly due to reobstruction and migration of the stent, and to a lesser extent due to perforation secondary to device placement.Conclusion. Self-expanding metallic stents represent a therapeutic option in patients with colorectal obstruction caused by non-malignant stenosing pathology. When diversion through a stoma is not an option, this type of device is associated with high rates of clinical success and improvement in the patients' quality of life

Experiencing multiple concurrent functional gastrointestinal disorders is associated with greater symptom severity and worse quality of life in chronic constipation and defecation disorders.

BACKGROUND: Recent community-based studies have demonstrated that experiencing multiple concurrent functional gastrointestinal disorders (FGIDs) is associated with increased somatization, worse quality of life (QoL), and greater health care utilization. However, the presence of multiple overlapping FGIDs is unstudied specifically in chronic constipation and functional defecation disorders (FDD). We investigated the prevalence and impact of additional nonconstipation FGIDs on constipation severity, anorectal physiology, anxiety and depression, and QoL, in patients with chronic constipation and FDD. METHODS: One-hundred and forty-six consecutive patients with functional constipation or irritable bowel syndrome (IBS-C/IBS-M) presenting to a tertiary referral Neurogastroenterology Clinic were studied. In addition, 90/146 (62%) qualified for FDD due to abnormal defecatory physiology. Patients underwent comprehensive baseline assessment comprising anorectal physiology, Bristol Stool Chart, Rome questionnaire, Knowles-Eccersley-Scott-Symptom (KESS) constipation score, Hospital Anxiety, and Depression Scale, and modified 36-Item Short Form Health Survey (SF-36) for QoL. Additional FGIDs were diagnosed using Rome III criteria. KEY RESULTS: Additional nonconstipation FGIDs occurred in 85% of patients, with a mean of 2.1 (SD 1.6) additional FGIDs. Patients with four or more additional FGIDs experienced greater constipation severity compared to those with no additional FGIDs (p = 0.004). Comorbid FGIDs were associated with worse SF-36 scores for physical functioning (p < 0.001), role-physical (p = 0.005), bodily pain (p < 0.001), vitality (p = 0.008), social functioning (p = 0.004), and mental health index (p = 0.031). CONCLUSIONS AND INFERENCES: Functional gastrointestinal disorders comorbidity is highly prevalent in chronic constipation and defecatory disorders, and this is associated with greater symptom severity and worse QoL. Multimodal treatments targeting comorbid FGIDs may lead to superior outcomes.

Evaluation and comparison of the accuracy of transvaginal ultrasound and MRI for the diagnosis of deep rectal endometriosis: A cross-sectional study.

OBJECTIVE: To determine and compare the value of magnetic resonance imaging (MRI) and transvaginal sonography (TVS) in the diagnosis of rectal endometriosis. METHODS: In this cross-sectional study, 555 patients with rectal endometriosis, who had undergone MRI and TVS before laparoscopic operation, were included. The sensitivity, specificity, and accuracy of these two imaging modalities were evaluated and compared based on histopathologic reports and three different kinds of rectal endometriosis surgeries (shaving as a first group and disk and segmental resection methods combined as a second group). RESULTS: Sensitivity, specificity, accuracy, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of ultrasound in the diagnosis of rectal endometriosis were, respectively, 69.55% (65.4%-73.4%), 91.30% (72%-98.9%), 70.4% (66.4%-74.17%), 11.48% (9.77%-13.43%), 99.46% (98%-99.86%), 8.0 (2.12-30.1), and 0.3 (0.28-0.4). These values were 51.37% (47.1%-55.6%), 79.17% (57.8%-92.9%), 52.53% (48.3%-56.6%), 6.64% (5.39%-8.16%), 98.26% (96.26%-99.2%), 2.47 (1.13-5.4), and 0.6 (0.49-077) for MRI. Even though ultrasound had better accuracy for detection of superficial rectal endometriosis (Group 1) (P < 0.001), the sensitivity, specificity, and accuracy of both imaging modalities in diagnosis of deep rectal lesions (Group 2) were almost identical. CONCLUSION: TVS should be considered as a first-line modality for diagnosis of rectal endometriosis, mainly because of its greater availability, lower cost, and higher accuracy.

[The rôle of MRI in exploration anorectal pathologies]. / Place de l'IRM pour explorer les pathologies anorectales.

PLACE DE L'IRM POUR EXPLORER LES PATHOLOGIES ANORECTALES. L'imagerie par résonance magnétique (IRM) est l'un des examens d'imagerie les plus utiles à l'exploration des pathologies ano rectales. Elle est complémentaire de l'examen clinique et de l'endo scopie. Elle permet de fournir des données indispensables à une prise en charge optimale du patient par le proctologue, le chirurgien ou l'oncologue en fonction de la nature de l'atteinte anale ou rectale. Il est nécessaire de respecter les différentes indications de cet examen, qui ont été bien définies pour chaque pathologie par les différentes sociétés savantes. Le protocole de l'IRM varie en fonction de la zone explorée et de la pathologie suspectée. C'est pourquoi il est indispensable de fournir au radiologue les informations nécessaires telles que la suspicion diagnostique, les données cliniques, ainsi que les résultats des examens complémentaires déjà réalisés. Les indications les plus fréquentes de l'IRM en proctologie sont les tumeurs anales et rectales. L'IRM permet le bilan initial de l'extension locorégionale de la tumeur ainsi que le suivi oncologique précoce et tardif grâce à l'étude comparative des examens de surveillance par rapport au bilan initial. L'IRM est indispensable pour l'exploration des suppurations anopérinéales complexes, en particulier liées à la maladie de Crohn. Elle permet la réalisation du bilan lésionnel initial ainsi que le contrôle post-drainage. En cas de suspicion de maladie de Verneuil ou de sinus pilonidal infecté, l'IRM participe à l'orientation vers le diagnostic étiologique. La déféco-IRM est une variante particulière de l'IRM pelvienne et périnéale. Elle fait partie du bilan des dysfonctions du plancher pelvien, car elle permet l'étude du comportement des différents organes pelviens au cours des efforts de poussée et de défécation. Les fissures anales et les thromboses hémorroïdaires sont les causes les plus fréquentes de douleurs anales. Leur diagnostic est purement clinique. En cas d'examen proctologique normal, l'IRM sert à chercher une autre cause à ces douleurs.

THE ROLE OF MRI IN EXPLORATION ANORECTAL PATHOLOGIES. Magnetic resonance imaging (MRI) is one of the most useful imaging modalities for the exploration of anorectal pathologies. It is complementary to the clinical examination and endoscopy. It provides essential elements for optimal care of the patient by the proctologist, the surgeon or the oncologist depending on the nature of the anal or rectal condition. It is necessary to respect the different indications of this exam which have been well defined for each pathology by the different scientific societies. The MRI protocol varies depending on the site to be investigated and the pathology suspected. Therefore, it is essential to provide the radiologist with the necessary information such as the diagnostic suspicion, clinical findings, and the results of previous paraclinical examinations. MRI ensures the initial assessment of the locoregional extension of the tumor as well as the early and late oncological follow-up thanks to the comparative study of the surveillance examinations with the initial exam. MRI is essential for the assessment of complex anoperineal suppurations, in particular those related to Crohn's disease. It is necessary for the initial lesional assessment and for the post-drainage control. In case of suspicion of Verneuil's (hidradenitis suppurativa) disease or infected pilonidal sinus, MRI helps to orientate towards the right etiological diagnosis. MR defecating proctography is a particular variant of pelvic and perineal MRI. It is performed as part of the assessment of pelvic floor dysfunctions because it allows the study of the dynamics of the different pelvic organs during straining and defecation. Anal fissures and hemorrhoidal thrombosis are the most frequent etiologies of anal pain. Their diagnosis is purely clinical. If the proctological examination is normal, MRI is used to search for other causes of anal pain.

Correlation of endoscopic findings with suspected intestinal endometriosis in the distal sigmoid and rectum as observed on transrectal ultrasonography

Introduction: Colonoscopy enables detailed endoscopic evaluation of the interior of the colon. Changes observed via colonoscopy may be subtle or pronounced and can sometimes mimic those of other diseases, such as deep intestinal endometriosis. The diagnosis of endometriosis in the distal sigmoid and rectum by colonoscopy has been described in previous case reports. Objective: We aimed to correlate the endoscopic changes found in the distal sigmoid and rectum with the presence of endometrial deposits confirmed by transrectal ultrasound (TRUS). Methods: We included 50 female patients referred to the endoscopy department at our institution for colonoscopy, rectosigmoidoscopy, or TRUS, who exhibited one or more symptoms associated with endometriosis. Results: The colonoscopic findings were normal in 36 patients but showed alterations in 14 patients. Among the latter, TRUS revealed involvement of the sigmoid and/or rectal wall in 11 patients. Conclusions: The endoscopic changes in the distal sigmoid or rectum described in this study were strongly associated with endometrial deposits confirmed using TRUS. (AU)

Advancements in Rectal Drug Delivery Systems: Clinical Trials, and Patents Perspective.

The rectal route is an effective route for the local and systemic delivery of active pharmaceutical ingredients. The environment of the rectum is relatively constant with low enzymatic activity and is favorable for drugs having poor oral absorption, extensive first-pass metabolism, gastric irritation, stability issues in the gastric environment, localized activity, and for drugs that cannot be administered by other routes. The present review addresses the rectal physiology, rectal diseases, and pharmaceutical factors influencing rectal delivery of drugs and discusses different rectal drug delivery systems including suppositories, suspensions, microspheres, nanoparticles, liposomes, tablets, and hydrogels. Clinical trials on various rectal drug delivery systems are presented in tabular form. Applications of different novel drug delivery carriers viz. nanoparticles, liposomes, solid lipid nanoparticles, microspheres, transferosomes, nano-niosomes, and nanomicelles have been discussed and demonstrated for their potential use in rectal administration. Various opportunities and challenges for rectal delivery including recent advancements and patented formulations for rectal drug delivery have also been included.

Acute Hemorrhagic Rectal Ulcer Syndrome: A Known Yet Often Overlooked Etiology of Gastrointestinal Bleeding in Chronically Ill Patients.

Acute Hemorrhagic Rectal Ulcer Syndrome (AHRUS) is a known and potentially overlooked cause of severe gastrointestinal bleeding in patients with critical illness. It presents as a sudden and brisk painless bleed. It is common among elderly patients who have chronic conditions such as coronary artery diseases associated with the use of anti-platelets, diabetes mellitus, hypoalbuminemia, liver diseases, sepsis, stroke, and chronic renal failure on hemodialysis. AHRUS could result in fatal gastrointestinal hemorrhage. Here, we report a case of acute hemorrhagic rectal ulcer with the above-mentioned risk factors and make the argument that AHRUS should be an important differential in a similar population presenting with a gastrointestinal bleed.

Type-specific concurrent anogenital HPV detection among young women and MSM attending Dutch sexual health clinics.

OBJECTIVES: This study aimed to investigate type-specific concurrent anogenital human papillomavirus (HPV) detection and examine associations with concurrent detection. METHODS: Data from a Dutch repeated cross-sectional study among young sexual health clinic visitors (Papillomavirus Surveillance among STI clinic Youngsters in the Netherlands) between 2009 and 2019 were used. Cohen's kappa was used to assess the degree of type-specific concordance of HPV detection between anal and genital sites for 25 HPV genotypes for women and men who have sex with men (MSM) separately. Associations with type-specific concurrent HPV were identified. Receptive anal intercourse (RAI) was forced into the model to investigate its influence. RESULTS: Among women (n=1492), type-specific concurrent anogenital detection was common; kappa was above 0.4 for 20 genotypes. Among MSM (n=614), kappa was <0.4 for all genotypes. The only significant association with type-specific concurrent anogenital detection among women was genital chlamydia (adjusted OR 1.5, 95% CI 1.1 to 2.2). RAI was not associated. CONCLUSIONS: Type-specific concurrent anogenital HPV detection was common among young women, and uncommon among MSM. For women, concurrent HPV detection was associated with genital chlamydia. Our results are suggestive of autoinoculation of HPV among women.

Early Diagnosis of Anal Canal Duplication: The Importance of a Physical Examination.

Anal canal duplication (ACD) is an extremely rare congenital anomaly of the intestinal tract that presents as an extra opening of the anal canal without communication with the anorectum. We present the case of a five-year-old male presenting to the pediatrician without symptoms and upon physical examination, a duplicated anal canal along the midline was discovered. The patient was admitted for surgery and the canal was removed via mucosal stripping. Postoperatively, the patient recovered well. The present study aims to expand on our knowledge of a very rare pathological entity and emphasize the importance of a complete pediatric physical examination.

Universal lymphogranuloma venereum (LGV) testing of rectal chlamydia in men who have sex with men and detection of asymptomatic LGV.

BACKGROUND: Lymphogranuloma venereum (LGV) is caused by Chlamydia trachomatis serovars L1-L3. This study determined the positivity for LGV testing before and after introduction of universal LGV testing of positive rectal Chlamydia trachomatis samples in men who have sex with men (MSM). METHODS: From March 2015 to February 2018, MSM with rectal C. trachomatis were not routinely tested for LGV at the Melbourne Sexual Health Centre unless they had HIV or symptoms of proctitis. From February 2018, universal testing for LGV of all positive rectal C. trachomatis specimens in men over the age of 25 years, regardless of symptoms was undertaken. LGV positivity was defined as the detection of LGV-associated C. trachomatis serovars. RESULTS: There were 3429 and 4020 MSM who tested positive for rectal chlamydia in the selective and universal LGV-testing periods, respectively. Of the total 3027 assessable specimens in both periods, 97 (3.2%; 95% CI 2.6% to 3.9%) specimens tested positive for LGV. LGV positivity in the selective testing period was higher than in the universal testing period (6.6% (33/502) vs 2.5% (64/2525), p<0.001). The proportion of LGV cases that were asymptomatic increased from 15.2% (5/33) in the selective testing period to 34.4% (22/64) in the universal testing period (p=0.045). Of the 70 symptomatic LGV cases symptoms included rectal discharge (71.4%, n=45) and rectal pain (60.0%, n=42). CONCLUSION: Universal LGV testing of all positive rectal chlamydia samples in MSM compared with selective testing led to the detection of asymptomatic rectal LGV, which constituted 34% of rectal LGV cases.

Solitary rectal ulcer syndrome (SRUS): observational case series findings on MR defecography.

OBJECTIVE: Radiological findings in solitary rectal ulcer syndrome (SRUS) are well described for evacuation proctography (EP) but sparse for magnetic resonance defecography (MRD). In order to rectify this, we describe the spectrum of MRD findings in patients with histologically proven SRUS. MATERIALS AND METHODS: MRD from twenty-eight patients (18 female; 10 males) with histologically confirmed SRUS were identified. MRD employed a 1.5-T magnet and a standardized technique with the rectal lumen filled with gel and imaged sagittally in the supine position, before, during, and after attempted rectal evacuation. A single radiologist observer with 5 years' experience in pelvic floor imaging made the anatomical and functional measurements. RESULTS: Sixteen patients (10 female) demonstrated internal rectal intussusception and 3 patients (11%) demonstrated complete external rectal prolapse. Anterior rectoceles were noted in 12 female patients (43%). Associated anterior and middle compartment weakness (evidenced by excessive descent) was observed in 18 patients (64%). Cystocele was found in 14 patients (50%) and uterine prolapse was noted in 7 patients (25%). Enterocoeles were detected in 5 patients (18%) and peritoneocoele in 5 patients (18%). None had sigmoidocoele. Sixteen patients (57%) demonstrated delayed voiding and 13 patients (46%) incomplete voiding, suggesting defecatory dyssynergia. CONCLUSION: MRD can identify and grade both rectal intussusception and dyssynergia in SRUS, and also depict associated anterior and/or middle compartment descent. Distinction between structural and functional findings has important therapeutic implications. KEY POINTS: MRD can identify and grade both rectal intussusception and dyssynergia in patients with SRUS. MRD is an acceptable substitute to evacuation proctography in assessing anorectal dysfunctions when attempting to avoid ionizing radiation. SRUS influences the pelvic floor globally. MRD depicts associated anterior and/or middle compartment prolapse.

Úlcera rectal solitaria como simulador de cáncer colorrectal y enfermedad de Crohn: reporte de caso / Solitary rectal ulcer simulating colorectal cancer and Crohn's disease: Case report

Abstract Solitary rectal ulcer is a rare condition of benign nature that must be differentiated from other disorders with defined pathophysiological mechanisms and varied symptoms. The following is the case of a 31-year-old female patient with no relevant history, who consulted our institution due to symptoms of rectal bleeding associated with episodes of diarrhea for three years, who received multiple diagnoses.

Cytomegalovirus proctitis as a complication of COVID-19 with immunosuppressive treatments.

We report a case of reactivated biopsy-proven cytomegalovirus proctitis complicating the course of severe COVID-19 pneumonia treated with dexamethasone, anakinra and lopinavir/ritonavir. No other contributing factor was found than iatrogenic immunosuppression and COVID-19 immune dysregulation. We draw attention to the immunosuppressive risk when treating severe COVID-19 pneumonia with immunomodulators.
