Pleasurable and problematic receptive anal intercourse and diseases of the colon, rectum and anus.

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.

[Implementation of fluorescent imaging technology in endovideosurgical treatment of colorectal endometriosis]. / Vnedrenie tekhnologii fluorestsentnoi vizualizatsii v endovideokhirurgicheskoe lechenie kolorektal'nogo endometrioza.

The article includes a clinical case of a patient with deep infiltrating endometriosis with rectum involving and using intraoperative controlled fluorescence in order to increase the radicality of surgery and improve the prognosis of the disease. Surgical excision of the endometrioitic nodules is the only effective way of treating patients with colorectal endometriosis in terms of relieving pain, improving quality of life and restoring reproductive function. The possible types of surgical interventions can be performed: endometrioid lesion shaving, discoid or circular intestinal resection with anastomosis. The extent of the operation is determined by the following morphological parameters: the number of endometrioid infiltrates of the intestinal wall, the size of each of them, the degree of involvement of the intestine circumference, the depth of the intestinal wall lesion, the distance from the level of anus to the endometriotic nodule and lymphatic dissemination.

London Protocol under water-perfused HRM in a healthy population, towards novel 3D manometric parameters in an evaluation of anorectal functional disorders.

BACKGROUND/AIM: London Protocol (LP) and Classification allied to high-resolution manometry (HRM) technological evolution has updated and enhanced the diagnostic armamentarium in anorectal disorders. This study aims to evaluate LP reproducibility under water-perfused HRM, provide normal data and new parameters based on 3D and healthy comparison studies under perfusional HRM. METHODS: Fifty healthy (25 F) underwent water-perfused 36 channel HRM based on LP at resting, squeeze, cough, push, and rectal sensory. Additional 3D manometric parameters were: pressure-volume (PV) 104mmHg2.cm (resting, short and long squeeze, cough); highest and lowest pressure asymmetry (resting, short squeeze, and cough). Complementary parameters (CP) were: resting (mean pressure, functional anal canal length); short squeeze (mean and maximum absolute squeeze pressure), endurance (fatigue rate, fatigue rate index, capacity to sustain); cough (anorectal gradient pressure); push (rectum-anal gradient pressure, anal canal relaxation percent); recto-anal inhibitory reflex (anal canal relaxation percent). RESULTS: No difference to genders: resting (LP, CP, and 3D); short squeeze (highest pressure asymmetry); endurance (CP); cough (CP, highest and lowest pressure asymmetry); push (gradient pressure); rectal sensory. Higher pressure in men: short squeeze (maximum incremental, absolute, and mean pressure, PV, lowest pressure asymmetry); long squeeze (PV); cough (anal canal and rectum maximum pressure, anal canal PV); push (anal canal and rectum maximum pressure). Anal canal relaxation was higher in women (push). CONCLUSIONS: LP reproducibility is feasible under water-perfused HRM, and comparative studies could bring similarity to dataset expansion. Novel 3D parameters need further studies with healthy and larger data to be validated and for disease comparisons. KEY POINTS: • London Protocol and Classification allied with the technological evolution of HRM (software and probes) has refined the diagnostic armamentarium in anorectal disorders. • Novel 3D and deepening the analysis of manometric parameters before the London Classification as a contributory diagnostic tool. • Comparison of healthy volunteers according to the London Protocol under a perfusional high-resolution system could establish equivalence points.

Presentaciones de la sífilis anorrectal: la gran simuladora / Anorectal syphilis presentations: the great pretender

Antecedentes: La sífilis es una infección sexualmente transmisible sistémica crónica que afecta a docenas de millones de personas al año. A nivel anorrectal, su manifestación polimórfica obliga al diagnóstico diferencial con enfermedades anorrectales benignas y malignas. Objetivo: Describir las diferentes presentaciones de la sífilis anorrectal a propósito de 5 casos clínicos. Método: Estudio observacional, retrospectivo, descriptivo. Resultados: La mayoría de los pacientes fueron VIH positivos en edad sexual activa. Las manifestaciones registradas, al igual que las reportadas en la bibliografía fueron las fisuras, úlceras perianales y pseudotumores. Conclusiones: La sífilis es considerada "la gran simuladora". En la localización anorrectal se requiere una alta sospecha diagnóstica para diferenciarla de presentaciones similares de otras enfermedades anales benignas, la enfermedad inflamatoria intestinal y el cáncer anorrectal, con el fin de evitar el consiguiente riesgo de sobretratamiento.

Background: Syphilis is a chronic systemic sexually transmitted infection that affects tens of millions of people annually. At the anorectal level, its polymorphic manifestation requires differential diagnosis with benign and malignant anorectal diseases. Objective: To review the presentation of anorectal syphilis from 5 clinical cases. Methods: Observational, retrospective, descriptive study. Results: Most of the patients were HIV positive in sexually active age. The manifestations recorded and reported in the literature were fissures, perianal ulcers, and pseudotumors. Conclusions: Syphilis is considered "the great pretender". In anorectal syphilis, a high diagnostic suspicion is needed to differentiate it from similar presentations due to other anal conditions, inflammatory bowel disease, and anorectal cancer, to avoid the consequent risk of overtreatment.

Argon plasma coagulation: an effective treatment for solitary rectal ulcer syndrome.

BACKGROUND: Solitary rectal ulcer syndrome (SRUS) is a very rare benign defecation disorder characterized by distinct clinical features and histological findings. Conventional measures are often shown to be ineffective for the treatment of ulcers. Argon plasma coagulation (APC) has recently been shown to be an effective treatment method for SRUS that is refractory to conventional therapy. OBJECTIVES: Determine the efficacy of APC treatment for patients suffering from SRUS. DESIGN: Prospective, single center. SETTINGS: Gastroenterology department at a military hospital in Pakistan. PATIENTS AND METHODS: This prospective study included patients with symptoms of rectal bleeding diagnosed with SRUS. Patients were recruited on the basis of clinical, sigmoidoscopic, and histological findings from September 2022 to March 2023. All patients had received conventional treatment initially and were assessed for persistence of symptoms. APC was performed only for those patients who were refractory to standard treatment. MAIN OUTCOME MEASURES: Effectiveness of APC for resistant SRUS. SAMPLE SIZE: 99 patients. RESULTS: The 99 patients diagnosed with SRUS had a median (minimum-maximum) age of patients was 20 (9-41) years. All the patients had undergone conventional treatment, which included the use of laxatives, drinking plenty of water and practicing biofeedback. After this standard treatment, 19 patients (19.19%) recovered fully. However, the remaining 80 patients did not show improvement and underwent APC sessions, out of which 61 patients (76.3%) achieved complete healing of ulcers, while the remaining 19 (23.8%) had no improvement at all. None of the patients reported post session complications. CONCLUSION: APC is an effective therapy with very promising results for rectal ulcer hemorrhage. It also helps with ulcer healing and alleviates clinical symptoms. However, further controlled investigations are required to consolidate the use of APC in SRUS patients. LIMITATIONS: Single centered.

Using Self-Reported Sexual Positioning as an Indicator for Rectal Chlamydia and Gonorrhea Screening Among Men Who Have Sex With Men in China: A Missed Opportunity.

BACKGROUND: Rectal Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections among men who have sex with men (MSM) are escalating public health concerns. This study aimed to explore (1) the reliability of self-reported sexual positioning as an indicator for rectal CT and NG screening, and (2) factors associated with rectal CT and NG infections in Shenzhen, China. METHODS: A cross-sectional study was conducted in 2 settings in Shenzhen, China, from April 1, 2021, to March 31, 2022. Data on sociodemographic characteristics, sexual behaviors, and basic CT knowledge were collected. Urine and self-collected rectal swabs were collected for CT and NG testing. RESULTS: In total, 195 MSM participated in the study, and 5.1% tested positive for urogenital CT, 29.2% for rectal CT, 1.0% for urogenital NG, and 8.2% for rectal NG. Among those who reported exclusively insertive anal sex, 69.2% of CT infections and 85.7% of NG infections would have remained undetected with urine testing alone. Risk factors for rectal CT infection included engaging in both insertive and receptive anal sex, with a significant association found for coinfection with rectal NG. CONCLUSIONS: Self-reported sexual positioning was found to be an unreliable indicator for CT and NG screening, as a substantial proportion of infections would have remained undetected. The findings suggest that CT and NG screening in China should be offered to all MSM regardless of self-reported sexual positioning, and that the dual CT/NG testing is recommended.

Effective Treatment of Solitary Rectal Ulcer Syndrome by Using Photobiomodulation Therapy: A Case Report.

Objective: To investigate the efficacy of Photobiomodulation therapy (PBMT) for the treatment of solitary rectal ulcer syndrome (SRUS). Background: SRUS is a benign disease, diagnosed by symptoms, clinical, and histological findings. PBMT has been reported for the treatment of various inflammation-based diseases including aphthous ulcer, but still no such study on the treatment of SRUS is published. Materials and methods: A 29-year Asian women, diagnosed for SRUS of 0.57 cm diameter, was treated by a laser at 635 nm through seven sessions. Laser fluence of 85 J/cm2 was delivered to ulcer lesion during each session for 10 min. Clinical results were valued by physician with sigmoid probe throughout PBMT sessions and no medicines were prescribed to the patient. Results: After seven sessions, the lesion was completely healed with 100% clinical response. In follow-up, patient did not respond to any additional/recurring abnormality, and no side effects were observed. Conclusions: In conclusion, PBMT by using laser at 635 nm is an effective treatment for SRUS without any side effects and patient remained comfortable throughout treatment sessions. Patient registration No. H-744/23.

Anorectal Emergencies.

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.

A Case Report of Profuse Bleeding in the Lower Gastrointestinal Tract due to Dieulafoy Lesion in the Rectum.

Dieulafoy lesion is a rare condition that usually occurs in cases of gastric bleeding in the upper gastrointestinal tract. However, this condition can also occur in the lower gastrointestinal tract but less frequently. The lesion is an arteriolar malformation that extends to the submucosa, causing erosion and bleeding. Meanwhile, this is a case of a 67-year-old woman presenting with a bright red bloody stool prior to admission, as well as a history of constipation which was relieved by digital stool evacuation two weeks earlier. The medical history of the patient reveals episodes of  repeated ischaemic stroke for over seven years and three months, which has led to other conditions such as right-sided paralysis, transcortical motor aphasia, and neurogenic dysphagia. The patient was routinely on antithrombotic medications, which was stopped during hospitalisation where repeated packed cell transfusion was done in order to avoid hematochezia. The patient needed the support of her caregiver most of the time since she was bedridden. Furthermore, the haemostasis and platelet function of the patient were normal. On colonoscopy, there was the discovery of a small lesion of about 3mm in her rectum, protruding into the lumen and pulsated, which was discovered to be Dieulafoy's lesion. Subsequently, this lesion was closed using rubber band ligation, and after a month, there was no recurrence of the lower gastrointestinal bleeding.

Optimizing the Utility of Anorectal Manometry for Diagnosis and Therapy: A Roundtable Review and Recommendations.

BACKGROUND & AIMS: Anorectal manometry (ARM) is a comprehensive diagnostic tool for evaluating patients with constipation, fecal incontinence, or anorectal pain; however, it is not widely utilized for reasons that remain unclear. The aim of this roundtable discussion was to critically examine the current clinical practices of ARM and biofeedback therapy by physicians and surgeons in both academic and community settings. METHODS: Leaders in medical and surgical gastroenterology and physical therapy with interest in anorectal disorders were surveyed regarding practice patterns and utilization of these technologies. Subsequently, a roundtable was held to discuss survey results, explore current diagnostic and therapeutic challenges with these technologies, review the literature, and generate consensus-based recommendations. RESULTS: ARM identifies key pathophysiological abnormalities such as dyssynergic defecation, anal sphincter weakness, or rectal sensory dysfunction, and is a critical component of biofeedback therapy, an evidence-based treatment for patients with dyssynergic defecation and fecal incontinence. Additionally, ARM has the potential to enhance health-related quality of life and reduce healthcare costs. However, it has significant barriers that include a lack of education and training of healthcare providers regarding the utility and availability of ARM and biofeedback procedures, as well as challenges with condition-specific testing protocols and interpretation. Additional barriers include understanding when to perform, where to refer, and how to use these technologies, and confusion over billing practices. CONCLUSIONS: Overcoming these challenges with appropriate education, training, collaborative research, and evidence-based guidelines for ARM testing and biofeedback therapy could significantly enhance patient care of anorectal disorders.

Síndrome de úlcera rectal solitaria en un centro hospitalario de tercer nivel entre los años 2010-2020: ¿estamos haciendo bien las cosas? / Solitary rectal ulcer syndrome in a tertiary care hospital between 2010-2020: are we doing things right?

Introduction: Solitary rectal ulcer syndrome is a poorly studied pathology. Its diagnosis is established by the combination of clinical, endoscopic, histopathological and microbiological findings. The objective of this work is to describe the main clinical characteristics and characteristics of patients with solitary rectal ulcer treated at the Salamanca University Assistance Complex (CAUSA). Material and methods: Retrospective observational descriptive study, between 2010 and 2020. Results: Of the 157 patients studied, 52.9% (83) were men, with a mean age of 68.8 ± 18.2 years. The diagnostic delay was 6.85±16.56 months (1-84). Non-infectious etiology was described in 93.6% of cases, with nonspecific rectal ulcer (36%), solitary rectalulcer (14.9%) and actinic proctitis (14.2%) being the most frequent. Infections were studied in 56 patients, objectifying an infectious agent in 10 patients, the most frequent pathogens were Clostridoides difficile (40%), Cytomegalovirus (20%), Chlamydia trachomatis (10%) and Epstein Barr Virus (10%). The most frequent symptom was rectal bleeding (43.3%), followed by anemia (15.3%), constipation (10.8%), and diarrhea (6.37%). Symptom resolution occurred in 30.6% (48) of the patients and symptom recurrence was present in 10.2% (16). Conclusions: In most cases, the study of rectal ulcer syndrome is not carried out exhaustively, which determines a low rate of etiological diagnosis. In our series, adult males without etiological diagnosis predominate. It is essential to coordinate the different services involved and protocolize their management to optimize their diagnosis and treatment. (AU)

Introducción: El síndrome de úlcera rectal solitaria es una patología poco estudiada puede presentarse con sangrado rectal, y una sensación de evacuación incompleta. Su diagnóstico se establece por la combinación de hallazgos clínicos, endoscópicos, histopatológicos y microbiológicos. El objetivo de este trabajo es describir las principales características clínicas y de los pacientes con úlcera rectal solitaria atendidos en el Complejo Asistencial Universitario de Salamanca (CAUSA). Material y métodos: Estudio descriptivo observacional retrospectivo,entre los años 2010 y 2020. Resultados: De los 157 pacientes estudiados, 52,9 % (83) fueron hombres, con edad media de 68,8 ±18,2 años. El retraso diagnóstico fue de 6,85± 16,56 meses (1-84). La etiología no infecciosa se describió en el 93,6% de los casos, siendo más frecuente la úlcera rectal inespecífica (36%), úlcera rectal solitaria (14,9%) y proctitis actínica(14,2%). Se estudiaron infecciones en 56 pacientes, objetivándose un agente infeccioso en 10 pacientes, los patógenos más frecuentes fueron Clostridoides difficile (40%), Citomegalovirus (20%), Chlamydia trachomatis (10%) y Virus de Epstein Barr (10%). El síntoma más frecuente fue rectorragia (43,3%), seguido de anemia (15,3%), estreñimiento (10,8%), y diarrea (6,37%). La resolución de los síntomas tuvo lugar un 30,6% (48) de los pacientes y la recurrencia de la sintomatología estuvo presente en 10,2% (16). Conclusiones: En la mayoría de las ocasiones no se realiza de forma exhaustiva el estudio del síndrome de úlcera rectal solitaria, lo que condiciona una baja tasa del diagnóstico etiológico. En nuestra serie predominan varones adultos sin diagnóstico etiológico. Es imprescindible coordinar a los diferentes servicios implicados y protocolizar su manejo para optimizar su diagnóstico y tratamiento. (AU)

Long-term risk of repeated surgeries in women managed for endometriosis: a 1,092 patient-series.

OBJECTIVE: To assess the long-term risk of repeated surgery in women undergoing complete excision of endometriosis by an experienced surgeon and to identify circumstances leading up to repeat surgery. DESIGN: Retrospective study based on data recorded in a large prospective database. SETTING: University Hospital. PATIENT(S): A total of 1,092 patients managed for endometriosis, from June 2009 to June 2018, by one surgeon. INTERVENTION(S): Complete excision of endometriosis lesions. MAIN OUTCOME MEASURE(S): The recording of a repeated surgery linked to endometriosis performed during follow-up. RESULT(S): Endometriosis was exclusively superficial in 122 patients (11.2%) and 54 women (5%) had endometriomas without associated deep endometriosis nodules. Deep endometriosis was managed in 916 women (83.9%), leading to infiltration or not of the bowel in 688 (63%) and 228 (20.9%) patients, respectively. A majority of patients were managed for severe endometriosis infiltrating the rectum (58.4%). Mean and median follow-up was 60 months. A total of 155 patients underwent a repeated surgery relating to endometriosis; 108 procedures were required because of recurrences (9.9%), 39 surgeries were related to the management of infertility by assisted reproductive techniques (3.6%), and in 8 surgeries, a direct relationship between surgery and endometriosis was probable but not certain (0.8%). The majority of procedures involved hysterectomy for adenomyosis (n=45, 4.1%). The probability of requiring repeated surgery at 1, 3, 5, 7, and 10 years was 3%, 11%, 18%, 23%, and 28%, respectively. Cox's multivariate model identified postoperative pregnancy and hysterectomy as being statistically significant independent predictors for a reduction in the probability of having a repeated surgery, after adjustment on continuous postoperative amenorrhea, the main localization of the disease, and management for endometriosis infiltrating the rectum during the first surgery. CONCLUSION(S): Up to 28% of patients may require a repeated surgical procedure during the 10 years after complete excision of endometriosis. Conservation of the uterus is followed by an increased risk of repeated surgery. The study is based on outcomes resulting from a single surgeon, which limits the generalizability of results.

High Prevalence of Rectal Chlamydia and Gonorrhea Among Men Who Have Sex With Men Who Do Not Engage in Receptive Anal Sex.

BACKGROUND: In the United States, annual screening for rectal gonorrhea and chlamydia is only recommended for men who report receptive anal sex (RAS), but other behaviors (e.g., rimming) may lead to rectal Chlamydia trachomatis and Neisseria gonorrhoeae acquisition. METHODS: We enrolled individuals assigned male sex at birth who reported sex with men and denied RAS in the past 2 years or reported RAS 1 to 2 years ago but were tested and treated since last RAS. Participants enrolled in-person at the Sexual Health Clinic in Seattle, Washington (December 2019-July 2022), or online (July 2021-March 2022). Participants completed a survey that asked about 13 non-RAS behaviors and self-collected a rectal swab for gonorrhea/chlamydia nucleic acid amplification testing. We used log binomial regression to estimate the prevalence of rectal gonorrhea/chlamydia (adjusted prevalence ratio [aPR]) by behavior, adjusting for all other behaviors. RESULTS: We enrolled 292 participants (247 in-person and 45 online); 277 (95%) had nucleic acid amplification testing results. Rectal gonorrhea/chlamydia test positivity was 14.1% overall: 10.5% for rectal chlamydia and 4.3% for rectal gonorrhea. Most participants (70%) reported ≥1 behavior that involved direct contact with their anus. We observed a higher risk of rectal chlamydia for those who did versus did not report perianal play at 12 months (aPR, 2.39; 95% confidence interval, 1.10-5.22) and 2 months (aPR, 2.21; 95% confidence interval, 1.02-4.79). This was the only behavior significantly associated with testing positive. CONCLUSIONS: Rectal C. trachomatis and N. gonorrhoeae prevalence was high among men who deny RAS, suggesting other possible routes of acquisition. Rectal screening for those who deny RAS should be made with careful consideration of individual- and population-level effects.

Vaseline gauze packing for the treatment of acute hemorrhagic rectal ulcer: Two case reports.

RATIONALE: Acute hemorrhagic rectal ulcer (AHRU) is a relatively rare condition characterized by sudden onset, painlessness, and massive hematochezia in patients with severe underlying conditions. When AHRU is encountered, they can often be successfully controlled endoscopically, though recurrent bleeding is common and an alternative treatment must be sought if initial endoscopic treatment fails. We report 2 cases of AHRU which were successfully treated with Vaseline gauze packing after the failure of endoscopic hemostasis. PATIENT CONCERNS: The first patient was an 88-year-old female that visited our emergency department with hematochezia. She was immobilized because of a left pelvic bone fracture resulting from a slip-down. The initial endoscopy showed fresh blood in her rectum with diffuse ulceration near the dentate line but no active bleeding. However, Massive hematochezia has recurred during conservation. A second patient, an 86-year-old female, debilitated because of schizophrenia, dementia, and past subdural hemorrhage, visited our emergency department, also with massive hematochezia. Her initial endoscopy showed deep ulceration near the dentate line. After admission, she experienced massive hematochezia from an AHRU with an exposed vessel but endoscopic hemostasis failed to control bleeding. DIAGNOSES: Both patients were diagnosed as AHRU based on the endoscopic findings. INTERVENTIONS: In both cases, Vaseline gauze packing was performed for bleeding control. OUTCOMES: After Vaseline gauze packing, no further bleeding occurred and follow-up endoscopy showed definitive improvement of ulcers. LESSONS: Based on these cases, we suggest that Vaseline gauze packing may be the alternative treatment for the AHRU which is located near the dentate line when endoscopic hemostasis is difficult or failed. Although further research is needed, Vaseline gauze packing has several potential advantages for the treatment of AHRU, especially in cases involving critically ill elderly patients.
