Ano-rectal

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...

BACKGROUND: Positron emission tomography-magnetic resonance (PET-MR) attenuation correction is challenging because the MR signal does not represent tissue density and conventional MR sequences cannot image bone. A novel zero echo time (ZTE) MR sequence has been previously developed which generates signal from cortical bone with images acquired in 65 s. This has been combined with a deep learning model to generate a synthetic computed tomography (sCT) for MR-only radiotherapy. This study aimed to evaluate this algorithm for PET-MR attenuation correction in the pelvis...

Anal and rectal cancers were some of the first disease sites treated with brachytherapy due to the anatomic ease of implantation. As external beam radiotherapy grew in popularity the use of ano-rectal brachytherapy declined. However, the past few years have seen a steady resurgence in the use of brachytherapy in the ano-rectum supported by the use of large clinical series and randomized trials. The increasing acceptance by the surgical community of organ preservation as a valid treatment strategy for rectal cancer has encouraged the use of nonsurgical approaches and brachytherapy has shown itself to be a valuable tool for this...

BACKGROUND: The aim of this study was to evaluate pelvic MRI accuracy for measurement of anatomical land marks in severe fecal incontinent (FI) children with high imperforate anus (IA). MATERIALS AND METHODS: A total of 80 children (40 cases and 40 controls) aged more than 4 years with severe FI were assessed. Magnetic resonance imaging was performed by a radiologist with the same device. For pelvic anatomical land marks measurement, we measured the ano-rectal angel and hiatal/pc ratio...

BACKGROUND: Positron Emission Tomography-Magnetic Resonance (PET-MR) scanners could improve ano-rectal radiotherapy planning through improved Gross Tumour Volume (GTV) delineation and enabling dose painting strategies using metabolic measurements. This requires accurate quantitative PET images acquired in the radiotherapy treatment position. PURPOSE: This study aimed to evaluate the impact on GTV delineation and metabolic parameter measurement of using novel Attenuation Correction (AC) maps that included the radiotherapy flat couch, coil bridge and anterior coil to see if they were necessary...

A term neonate weighing 2900 g was referred in the first week of life with complaints of abdominal distension since birth. New onset respiratory distress was noted 36 hours prior to referral. Baby required non-invasive respiratory support and intravenous antibiotics as chest X-ray was suggestive of pneumonia. Ultrasound abdomen confirmed low ano-rectal malformation treated with cut-back anoplasty. Blood culture on admission grew a rare organism Delftia acidovorans The antibiotics were tailored as per the sensitivity pattern and continued for a duration of 14 days...

We present the case of a 63-year-old male with long-term anal pain. A pelvic MRI was performed showing a tumor arising from the intersphincteric extending into the submucosal layer of the posterior rectal wall. The image was compatible with a cT4N0 ano-rectal carcinoma without any distant metastasis on the CT scan. Histopathology showed neoplastic proliferation cells arranged in nodules and nidus consistent with anal glands adenocarcinoma with a positive immunohistostaining for CK7 and MUC5+ .

BACKGROUND: A large proportion of patients with preoperative enterocolitis still have enterocolitis persisting even after surgery while others resolve thereafter. Some researchers have studied Calprotectin, C-reactive protein (CRP), Blood and Plasma viscosity as markers of inflammation, hence, the choice of their use. The aim of the study is to determine the sensitivity and reliability of Calprotectin, C-reactive protein (CRP), Blood and Plasma viscosity as biochemical predictors of enterocolitis in children with colorectal anomaly post-surgery at University College Hospital Ibadan...

Ano rectal manometry is one of the motility test in children performed by Pediatric gastroenterologist. It evaluates the motility function of anorectal tract. It is helpful for diagnosing children with constipation, rectal hypersensitivity, fecal incontinence, Hirschsprung's disease, anal achalasia and anorectal malformations. The most common indication to perform ano rectal manometry is to diagnose Hirschsprung's disease. It is a safe procedure. This paper discusses recent advances and reviews on anorectal motility disorders in children...

KEY CLINICAL MESSAGE: The reckless or ridiculous usage of high pressure compressed air could lead to disastrous consequences as demonstrated in this case. Injuries from a barotrauma can vary from a simple mucosal laceration to tension pneumoperitoneum causing abdominal compartment syndrome. Decompression by a wide-bore needle can be done as depicted in our patient to provide immediate relief. ABSTRACT: Rectal perforation most commonly occurs due to trauma, but rarely due to a high pressure compressed air passing through the anus as a part of playful joke...

OBJECTIVES: Monkeypox, a zoonotic orthopoxvirus, has spread to many countries in recent months, involving mostly men who have sex with men (MSM) with multiple partners. Clinical presentation includes skin lesions, systemic signs, and less frequently skin superinfections, or ano-rectal and ophthalmic involvements. We aim to detail cases of myocarditis attributable to monkeypox, an entity that has been poorly described. METHODS: This is a descriptive case series reporting three cases of myocarditis that occurred in monkeypox-infected patients in France in 2022...

AIMS: The aim of this study is to investigate (i) whether pelvic floor muscle (PFM) shortening can be enhanced by provision of training focused on striated urethral sphincter (SUS) with feedback before prostatectomy, (ii) whether PFM shortening during voluntary efforts and coughing before and after prostatectomy differs between men who do and do not report symptoms of urinary incontinence 1 month after prostatectomy, and (iii) the relationship between severity of incontinence after prostatectomy and features of pelvic floor function (muscle shortening) and urethral length before and after prostatectomy...

INTRODUCTION: Peripheral or central neurological deseases are providers of anorectal disorders of variable clinical expression (constipation, dyschezia, faecal incontinence (FI)…). Anorectal manometry (ARM) participates in their exploration to determine the underlying mechanisms, guide and optimize treatments. The objective of this work was to determine if there is a pattern of ARM data in neurological populations. MATERIALS ET METHODS: Literature review from PubMed, Cochrane and Google scholar databases, using the following keywords: parkinsonian disorders; parkinson's disease; multiple slcerosis; neurolog*; spinal cord injury; spina bifida occulta; stroke; pudendal; endometriosis; peripheral nervous system diseases...

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...

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...

Background: Double incontinence (DI) is the concomitant presence of incontinence for urine and stool. Aim of this study is to assess prevalence of DI in patients with fecal incontinence (FI) undergoing Ano-Rectal Manometry (ARM) in a tertiary care center and to identify factors discriminating between both. Methods: Medical records of consecutive patients referred for ARM for FI during 2 years at University Hospital Brussels were retrospectively reviewed. Results from ARM, presence of diarrhea, diseases from recto-anal or peri-anal region, prior abdominal, proctological or urological surgery and neurological comorbidities were recorded...

Men who have sex with men (MSM) living with HIV are at increased risk of anal cancer and annual screening via digital ano-rectal examination (DARE) is recommended. Baseline audit (Cycle 1) was undertaken of the medical records of MSM living with HIV aged ≥50years (n =85) from 1 January 2017 to 31 December 2018, in line with guidelines at the time. Data collection included whether DARE was discussed and offered, and whether DARE was accepted or declined. We provided staff training and altered clinic proformas aiming to increase DARE...

Background: Prolonged mechanical ventilation (MV) should be avoided in neonates. Noninvasive ventilation (NIV) can facilitate weaning from MV but has risks for patients immediately following foregut surgery due to the potential risk of anastomotic leak. We evaluated the risk factors for prolonged MV following intestinal surgery in neonates. Methods: We retrospectively reviewed 253 neonates undergoing intestinal surgery in 2017-2018 to identify risk factors for prolonged MV, and determine the correlation between NIV and anastomotic leak in a tertiary neonatal intensive care unit that performs the greatest number of neonatal surgeries in Ontario...
