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.

Sexual Function After Surgical Treatment for Benign Anorectal Disorders.

Benign anorectal diseases such as hemorrhoidal disease, anal fissure, anal pruritus, perianal abscess, and fistula are the most common ones. The aim of this study was to assess sexual function in patients after surgery for benign anorectal diseases. Sixty-one male patients with perianal fistulas, operated on at Department of General Surgery, Faculty of Medicine, completed a self-administered questionnaire including the International Index of Erectile Function (IIEF) score. The median IIEF score of the postoperative patients was significantly higher (24, range [10-25]) than that of preoperative patients (22, range [5-25]), p < .0001. Sexual function is significantly influenced by surgery for benign anorectal diseases.

[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.

Transvaginal ultrasound with bowel preparation versus transvaginal ultrasound with bowel preparation and water contrast for diagnosing Recto-Sigmoid endometriosis. A systematic review and Meta-Analysis.

Transvaginal ultrasound is effective in diagnosing endometriosis involving the rectosigmoid bowel. Some authors suggest enhanced detection of rectosigmoid involvement with bowel preparation. Conversely, conflicting views argue that bowel preparation may not improve diagnostic precision, yielding similar results to rectal water contrast. No existing meta-analysis compares these approaches. Our study aims to conduct a meta-analysis to evaluate the diagnostic performance of transvaginal ultrasound with bowel preparation, with and without rectal water contrast. Studies published between 2000 and 2023 were searched in PubMed, Scopus, Cochrane and Web of Science. From 561 citations, we selected nine studies to include in this meta-analysis. The study quality was assessed using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2). The mean prevalence of endometriosis rectosigmoid was 43.6% (range 17,56-76,66%) in the group with bowel preparation and 64,80% (50,0-83,60%) for the group with bowel preparation and rectal water contrast. Pooled sensitivity and specificity were 93% and 94% for bowel preparation and 92% and 95% and for bowel preparation with water contrast. We conclude that, there was no significant difference between performing transvaginal ultrasound with intestinal preparation with and without water contrast. In clinical practice, the absence of a significant difference between these methods should be taken into account when making recommendations.

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.

Functional outcomes of bowel resection versus shaving or disc excision of colorectal endometriosis: a systematic review protocol.

INTRODUCTION: Endometriosis is a prevalent gynaecological condition for women of reproductive age worldwide. While endometriosis primarily involves the reproductive system, it can also infiltrate additional viscera such as the gastrointestinal tract. Patients with colorectal endometriosis can have severe symptoms that require surgical intervention. There are limited data available to guide the choice of resection technique based on the functional outcomes of bowel resection versus shaving or disc excision in treating colorectal endometriosis. This protocol aims to outline the methods that will be used in a systematic review of the literature comparing the functional outcomes of bowel resection to shaving and disc excision when surgically treating colorectal endometriosis. METHODS AND ANALYSIS: Papers will be identified through database searches, scanning reference lists of relevant studies and citation searching of key papers. Two independent reviewers will screen studies against eligibility criteria and extract data using standardised forms. Databases including MEDLINE, EMBASE and Cochrane will be searched from the beginning of each database until February 2024. The primary outcome is comparing the functional bowel outcomes between the different methods of surgical treatment. Secondary outcome will be quality of life, based on the Low Anterior Resection Syndrome score and the incidence of postoperative pain. A meta-analysis will be performed if the data are homogenous. ETHICS AND DISSEMINATION: This study does not require ethics approval. The results of the systematic review described within this protocol will be disseminated through presentations at relevant conferences and publication in a peer-reviewed journal. The methods will be used to inform future reviews. PROSPERO REGISTRATION NUMBER: CRD42023461711.

Intrarectal formalin treatment for haemorrhagic radiation-induced proctopathy: efficacy and safety.

AIM: Pelvic radiotherapy is limited by dose-dependent toxicity to surrounding organs. The aim of this prospective study was to evaluate the efficacy and safety of intrarectal formalin treatment for radiotherapy-induced haemorrhagic proctopathy (RHP) at the Royal Marsden Hospital. METHOD: Adult patients were enrolled. Haemoglobin was evaluated before and after formalin treatment. Antiplatelet and/or anticoagulation treatment and administration of transfusion were recorded. The interval between completion of radiotherapy and the first intrarectal 5% formalin treatment was assessed and the dose of radiotherapy was evaluated. Clinical assessment of the frequency and amount of rectal bleeding (rectal bleeding score 1-6) and endoscopic appearance (grade 0-3) were classified. Complications were recorded. RESULTS: Nineteen patients were enrolled, comprising 13 men (68%) and 6 women. The mean age was 75 ± 9 years. The median time between completion of radiotherapy and the first treatment was 20 months [interquartile range (IQR) 15 months] and the median dose of radiotherapy was 68 Gy (IQR 14 Gy). Thirty-two procedures were performed (average 1.7 per patient). In total, 9/19 (47%) patients were receiving anticoagulation and/or antiplatelet medication and 5/19 (26%) received transfusion prior to treatment. The mean value of serum haemoglobin before the first treatment was 110 ± 18 g/L and afterwards it was 123 ± 16 g/L (p = 0.022). The median rectal bleeding score before the first treatment was 6 (IQR 0) and afterwards 2 (IQR 1-4; p < 0.001), while the median endoscopy score on the day of first treatment was 3 (IQR 0) compared with 1 (IQR 1-2) on the day of the last treatment 1 (p < 0.001). One female patient with a persistent rectal ulcer that eventually healed (18 months of healing) subsequently developed rectovaginal fistula (complication rate 1/19, 5%). CONCLUSIONS: Treatment with intrarectal formalin in RHP is effective and safe.

Calcium polystyrene sulfonate-induced rectal ulcer causing E. coli native-valve infective endocarditis.

Escherichia coli-associated native-valve infective endocarditis is a rare disease that affects elderly patients with underlying risk factors such as diabetes mellitus, malignancy, and renal failure. Long-term use of calcium polystyrene sulfonate is a potential risk factor for gastrointestinal mucosal damage or even colorectal ulcers. Herein, we describe a fatal case of a 66-year-old Japanese man with diabetes mellitus and renal failure who was prescribed calcium polystyrene sulfonate (CPS) for 11 years and developed a CPS-induced rectal ulcer, leading to E. coli native-valve infective endocarditis. The patient was admitted to our hospital due to acute-onset impaired consciousness. As a result of the systemic investigation, he was diagnosed with E. coli bacteremia accompanied by multiple cerebral infarctions and an acute hemorrhagic rectal ulcer. Transesophageal echocardiography revealed a 20-mm vegetative structure on the mitral valve, resulting in a final diagnosis of E. coli-associated infective endocarditis. After rectal resection, mitral valve replacement surgery was performed; however, the patient died shortly after surgery. Pathological findings of the resected rectum showed deposition of a basophilic crystalline material suggesting the presence of CPS. Our case highlights the potential risk of colorectal ulcers in a long-term CPS user, which can trigger bacterial translocation and endocarditis as fatal complications.

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.

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.

Pain and opioid use after colorectal resection for benign versus malignant disease: A single institution analysis.

BACKGROUND: Studies comparing opioid needs between benign and malignant colorectal diseases are inconclusive. METHODS: Single institution analysis of prospectively maintained colorectal surgery database. Multiple regression analyses done on perioperative numeric pain scores (NPS) and opioids prescribed at discharge. RESULTS: 641 patients in Benign and 276 patients in the Malignant group. Unadjusted comparison revealed significantly higher NPS for the Benign than the Malignant group preoperative and postoperative day 0 (after surgery), 1, 2, and 3 (all p â€‹≤ â€‹0.001). Opioids prescribed at discharge were significantly higher in the Benign group (60.0% vs 51.1%, p â€‹= â€‹0.018). After regression analysis, there was no longer a significant difference in NPS (B â€‹= â€‹0.703, p â€‹= â€‹0.095) and opioids prescribed between groups [OR â€‹= â€‹0.803 (95%CI 0.586, 1.1), p â€‹= â€‹0.173]. CONCLUSIONS: Pain and opioids prescribed at discharge are not significantly different between benign and malignant diseases in an enhanced recovery pain management pathway that maximizes non-opioid multimodal analgesic strategies.

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.

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.

High-resolution rectoscopy using MHz optical coherence tomography: a step towards real time 3D endoscopy.

Colonoscopy and endoscopic ultrasound play pivotal roles in the assessment of rectal diseases, especially rectal cancer and inflammatory bowel diseases. Optical coherence tomography (OCT) offers a superior depth resolution, which is a critical factor for individualizing the therapeutic concept and evaluating the therapy response. We developed two distinct rectoscope prototypes, which were integrated into a 1300 nm MHz-OCT system constructed at our facility. The rapid rotation of the distal scanning probe at 40,000 revolutions per minute facilitates a 667 Hz OCT frame rate, enabling real-time endoscopic imaging of large areas. The performance of these OCT-rectoscopes was assessed in an ex vivo porcine colon and a post mortem human in-situ colon. The OCT-rectoscope consistently distinguished various layers of the intestinal wall, identified gut-associated lymphatic tissue, and visualized a rectal polyp during the imaging procedure with 3D-reconstruction in real time. Subsequent histological examination confirmed these findings. The body donor was preserved using an ethanol-glycerol-lysoformin-based technique for true-to-life tissue consistency. We could demonstrate that the novel MHZ-OCT-rectoscope effectively discriminates rectal wall layers and crucial tissue characteristics in a post mortem human colon in-situ. This real-time-3D-OCT holds promise as a valuable future diagnostic tool for assessing disease state and therapy response on-site in rectal diseases.

Combined Cystoscopic-Abdominal Versus Abdominal-Only Route for Complete Excision of Large Deep Endometriosis Nodules Infiltrating the Supratrigonal Area of the Bladder: A Comparative Study.

STUDY OBJECTIVE: Surgical excision of large deep endometriosis nodules infiltrating the bladder may be challenging, particularly when the nodule limits are close to the trigone and ureteral orifice. Bladder nodules have classically been approached abdominally. However, combining a cystoscopic with an abdominal approach may help to better identify the mucosal borders of the lesion to ensure complete excision without unnecessary resection of healthy bladder. This study aimed to compare classical excision of large bladder nodules by abdominal route with a combined cystoscopic-abdominal approach. DESIGN: Retrospective comparative study on data prospectively recorded in a database. Patients were managed from September 2009 to June 2022. SETTING: Two tertiary referral endometriosis centers. PATIENTS: A total of 175 patients with deep endometriosis infiltrating the bladder more than 2 cm undergoing surgical excision of bladder nodules. INTERVENTIONS: Excision of bladder nodules by either abdominal or combined cystoscopic-abdominal approaches. MEASUREMENTS AND MAIN RESULTS: A total of 141 women (80.6%) were managed by abdominal route and 34 women (19.4%) underwent a combined cystoscopic-abdominal approach. In 99.4% of patients, the approach was minimally invasive. Patients with nodules requiring the combined approach had a lower American Fertility Society revised score and endometriosis stage and less associated digestive tract nodules, but larger bladder nodules. They were less frequently associated with colorectal resection and preventive stoma. Operative time was comparable. The rate of early postoperative complications was comparable (8.8% vs 22%), as were the rates of ureteral fistula (2.2% vs 2.9%), bladder fistula (2.2% vs 0), and vesicovaginal fistula (0.7% vs 2.9%). CONCLUSION: In our opinion, the combined cystoscopic-abdominal approach is useful in patients with large bladder nodules with limits close to the trigone and ureteral orifice. These large deep bladder nodules seemed paradoxically associated to less nodules on the digestive tract, resulting in an overall comparable total operative time and complication rate.

Discoid excision for colorectal endometriosis associated infertility: A balance between fertility outcomes and complication rates.

OBJECTIVE: The objective of our study was to study the impact of discoid excision for deep endometriosis (DE) with colorectal involvement on fertility outcomes. METHODS: 49 patients with a desire for pregnancy treated with discoid excision for colorectal endometriosis in our endometriosis expert center between January 2015 and August 2020 were selected from our prospectively maintained database. Indications for surgery were either infertility and / or pelvic pain. Postoperative complications were graded according to the Clavien-Dindo classification. Fertility outcomes, both spontaneous and post-ART pregnancies, were analyzed. RESULTS: Among the 49 patients who underwent discoid excision exclusively (no other digestive resection) with a desire to conceive, 25 had a pregnancy after surgery and 24 did not. Double discoid excision was performed in 6.1 % of the cases (3/49). A colpectomy was performed in 12.2 % of the patients (6/49), and a protective stoma in 12.2 % (6/49). Fenestration of endometriomas was performed in 28.6 % of the patients (14/49), and parametrectomy in 40.8 % (20/49). The postoperative complication rate was 24.5 % (12/49) including 10.2 % (5/49) grade I, 12.2 % (6/49) grade II, and 2 % (1/49) grade III. Prior to surgery, 28 (57.1 %) patients had infertility including 13 (52 %) that successfully conceived following surgery and 15 (62.5 %) that remain infertile. Spontaneous pregnancy was achieved in 60 % (15/25) of infertile patients' prior surgery. The live-birth rate in patients conceiving spontaneously was 75 % (12/16). CONCLUSION: Our results support that discoid excision is safe and associated with good fertility outcomes. Whether first-line surgery using discoid excision is superior to first-line ART remains to be determined.
