Abstract

Aim: Data on the pathogenesis and symptoms of enterocele are limited. The objectives of this study were to determine the clinical phenotype of patients with enterocele, to highlight the main functional and/or anatomical associations and to improve the accuracy of the preoperative assessment of pelvic floor disorders. Method: A total of 588 patients who were referred to a tertiary unit for an anorectal complaint completed a self‐administered questionnaire and underwent physical examination, anorectal manometry and defaecography. Using defaecography, enterocele was defined as a radiological hernia of the small bowel into an enlarged rectovaginal space. One hundred and thirty‐five patients with enterocele were age‐ and gender‐matched with 270 patients without enterocele. Factors associated with enterocele were assessed using univariate and multivariate analysis models. Results: Patients with enterocele were less frequently obese than patients without enterocele (8/135 vs 36/270; P = 0.02) and more frequently had a past history of pelvic surgery (51/135 vs 75/270; P = 0.04). They complained more frequently of pelvic pain on bearing down (29/135 vs 24/270; P = 0.003), anal procidentia (37/135 vs 46/270; P = 0.01) and more frequently had irritable bowel syndrome (83/135 vs 131/270; P = 0.01) and severe constipation according to the Kess score (104/135 vs 182/270; P = 0.04). Anorectal function was comparable between the two groups. Patients with enterocele had more frequent rectoceles and overt rectal prolapses than patients without enterocele. Conclusions: Enterocele should be investigated in patients with chronic pelvic pain, overt rectal prolapse and/or a past history of pelvic surgery. [ABSTRACT FROM AUTHOR]

Abstract

Background: Recent studies have shown that pyloric distensibility is altered in 30-50% of gastroparetic patients but the number of diabetic patients included in prior reports has been small. The aim of the present study was to assess pyloric sphincter measurements in diabetic patients with gastroparesis and to determine whether diabetes characteristics were correlated to pyloric disfunction., Methods: Pyloric distensibility and pressure were measured using EndoFLIP ® system in 46 patients with diabetic gastroparesis (DGP) and compared with 21 healthy volunteers (HV), and 33 patients with idiopathic gastroparesis (IGP). Altered pyloric distensibility was defined as the measurement below 10 mm 2 /mmHg at 40 ml of inflation. In diabetic patients, blood glucose, glycated hemoglobin, duration, complications, and treatments were collected., Key Results: Mean pyloric distensibility at 40 ml of inflation was lower in DGP and IGP groups with, respectively, 10.8 ± 0.9 mm 2 /mmHg and 14.8 ± 2.2 mm 2 /mmHg in comparison with the HV group (25.2 ± 2.3 mm 2 /mmHg; p < 0.005). 56.5% of patients had a decreased pyloric distensibility in the DGP group, 51.5% of patients in the IGP group, and 10% of patients in the HV group. No correlation was found between pyloric sphincter measurements and diabetes characteristics, including blood glucose, glycated hemoglobin, diabetes mellitus type, neuropathy, or GLP1 agonists intake., Conclusion and Interferences: Pyloric sphincter distensibility and pressure were altered both in diabetic and idiopathic gastroparesis. Pyloric sphincter distensibility was not correlated to diabetes parameters., (© 2020 John Wiley & Sons Ltd.)

Abstract

Background: Little is known about the pathophysiological mechanisms of solitary rectal ulcer syndrome (SRUS)., Aims: We aim to identify the different phenotypes, taking into account complaints, anatomy and anorectal physiology., Methods: Complaints, endoscopy results, and physiology data of patients with histologically proven SRUS were collected and analysed. The associated anorectal diseases were faecal incontinence and obstructed defecation. The clinical aspects of SRUS were compared, and factors associated with anorectal diseases were identified., Results: Overall, 102 consecutive patients were included. The predominant lesion was a rectal ulcer (66%), and inflammation of the rectal wall was present in 42% of patients. Abnormal rectal capacities and/or rectal perception was observed in more than half. Nearly half (52%) of the patients met the criteria for obstructed defecation and they tended to more frequently have psychiatric disease (66.7% vs 33.3%; p=0.07). Patients with faecal incontinence (17%) reported more self-perception of anal procidentia (p=0.01) and were more likely to have inflammation of the rectal wall (p=0.02), high-grade internal rectal procidentia (p=0.06) and anal hypotonia (p=0.004); their maximum tolerable volume was lower (p=0.004)., Conclusion: The characteristics of patients with SRUS suggest different phenotypes. This may be a way to develop a comprehensive treatment strategy., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Editrice Gastroenterologica Italiana S.r.l.

Abstract

Objective: To investigate whether assessment of tissue oxygenation could help personalizing the mean arterial pressure (MAP) target in patients with septic shock., Methods: We prospectively measured near-infrared spectroscopy variables in 22 patients with septic shock receiving norepinephrine with a MAP>75 mmHg within the first six hours of intensive care unit (ICU) stay for patients with community-acquired septic shock and within the first six hours of resuscitation for patients with ICU-acquired septic shock. All measurements were performed at MAP>75 mmHg ("high-MAP") and at MAP 65-70 mmHg ("low-MAP") after decreasing the norepinephrine dose. Relative changes in StO 2 recovery slope (RS) >8% were considered clinically relevant., Results: After decreasing the norepinephrine dose by 45 ± 24%, MAP significantly decreased from 81[78;84] to 68[67;69]mmHg, whereas cardiac index did not change. On average, the StO 2 -RS significantly decreased between high and low-MAP from 2.86[1.87;4.32] to 2.41[1.14;3.72]%/sec with a large interindividual variability: the StO 2 -RS decreased by >8% in 14 patients, increased by >8% in 4 patients and changes were < 8% in 4 patients. These changes in StO 2 -RS were correlated with the StO 2 -RS at low-MAP (r = 0.57,p = 0.006). At high-MAP, there was no difference between patients exhibiting a relevant decrease or increase in StO 2 -RS., Conclusions: A unique MAP target may not be suitable for all patients with septic shock as its impact on peripheral oxygenation may widely differ among patients. It could make sense to personalize MAP target through a multimodal assessment including peripheral oxygenation., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: JLT and XM are members of the medical advisory board of Pulsion Medical Systems.

Abstract

There is no consensus on the treatment for solitary rectal ulcer syndrome (SRUS). This study aimed to obtain information from physicians treating patients with SRUS in a French medical surgical society to facilitate management plans and to develop a support algorithm. Members of the French National Society of Coloproctology (SNFCP) were invited to complete a survey that included twenty items about therapeutic management and healing criteria. Overall, 91 practitioners (median age: 52 [42-59] years) responded to the questionnaire; 64/91 (70.3%) were proctologists, and 27/91 (29.7%) were colorectal surgeons. Only 15 members (16.5%) followed more than 5 patients with SRUS per year. The therapeutic objectives were to improve both patient symptoms (100%) and quality of life (98.9%). Laxative treatment and first-line rehabilitation were agreed upon by 83.5% and 73% of the respondents, respectively. Surgery, mainly rectopexy, was offered after failed medical treatment by 81.1% of the practitioners (79.1%). The first-line strategy preferred by the professionals included laxatives and biofeedback rehabilitation. Surgical treatment, preferably rectopexy, was proposed as a second intervention. No consensus was reached regarding other therapeutic alternatives, and additional studies are required to clarify their indications., (Copyright © 2020 Editrice Gastroenterologica Italiana S.r.l.

Abstract

Background: 22q11.2 Deletion Syndrome (22q11DS) confers strongly increased genetic risk for multiple psychiatric disorders. Similarly to the general population, rates of psychiatric comorbidity suggest that common disease mechanisms are shared across dimensions of psychopathology. Such pleiotropic disease mechanisms remain however currently unknown. We hypothesized that pituitary dysmaturation, indicative of HPA-axis dysregulation, could correlate to reduced tolerance to daily life stressors and reflect pleiotropic risk factor for psychopathology. Moreover HPA-axis dysregulation could affect atypical cortical and hippocampal development previously described in 22q11DS., Methods: Pituitary volume, hippocampal volume and cortical thickness measures were obtained from T1-weighted MRI images in a large longitudinal cohort of youth with 22q11DS (115 subjects, 260 scans, age-range = 5.4-31.6) and healthy controls (151 subjects, 280 scans, age-range = 5.1-32.3). We explored effects of pituitary dysmaturation on tolerance to stress, psychopathology and neurodevelopment employing mixed-models linear regression. Associations of pituitary and cortical development were correlated with the expression pattern of glucocorticoid receptor gene NR3C1 obtained from the Allen-Human-Brain-Atlas., Results: We observed aberrant pituitary developmental trajectories in 22q11DS, with volumetric reductions emerging by young-adulthood (P = 0.0006). Longitudinal pituitary decline was associated with to reduced tolerance to stress (P = 0.04), higher overall psychopathology (P = 0.0003) and increased risk of psychiatric comorbidity (P = 0.02). Moreover, pituitary decline correlated with blunted growth of the right hippocampus (P = 0.03) and to increased cortical thinning of mostly temporal and orbitofrontal regions mediated by NR3C1 gene expression., Conclusion: Atypical pituitary development could reflect progressive extinction of HPAA due to chronic hyper-activation, in agreement with existing biochemical evidence in 22q11DS. HPAA dysregulation could represent and endophenotype that confers pleiotropic vulnerability to psychopathology and atypical neurodevelopment in 22q11DS., Competing Interests: Declaration of Competing Interest The authors report no conflict of interest., (Copyright © 2019 Elsevier Ltd.

Abstract

Background: Quality of life is increasingly seen as important, but remains difficult to assess in patients with functional anorectal complaints., Objective: We aimed to quantify quality of life and to analyse the symptomatic descriptors associated with a poor outcome in patients with faecal incontinence (FI) and/or constipation., Methods: The characteristics of the patients, data from self-administered questionnaires and from physical examinations were evaluated prospectively for all cases of functional anorectal disease over a period of thirteen years. Functional anorectal disease included faecal incontinence (FI) and/or constipation. Patients with scores in the lowest quartile of the Gastrointestinal Quality of Life Index (GIQLI) were considered to have suffered severe alterations to their quality of life, and were compared with the other patients., Results: In total, 1870 patients with functional anorectal disease were included (470 with a severely altered quality of life (GIQLI < 70)). Constipation predominated (1212/1870; 65.1%) and severe FI was frequent (761/1870; 40.9%). Severely altered quality of life was significantly associated with constipation (P = 0.0001), urinary urgency and incontinence (P = 0.0001), depression (P = 0.001), diabetes (P = 0.0224), severe FI (P = 0.0001), neurological disease (P = 0.0138) and liquid stools (P = 0.0002) in multivariate analysis., Conclusion: Several treatable factors are associated to an impaired quality of life in patients with functional anorectal disorders. Intervention studies are mandatory (stool consistency and frequency)., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Abstract

Background: The long-term management of perianal Crohn's disease for patients on anti-TNF-α therapy remains challenging., Aim: To evaluate the long-term course and complications of patients with perianal fistulas treated with anti-TNF-α based on their clinical remission and healing on MRI., Methods: Patients were evaluated clinically and by MRI. Deep remission was defined as clinical remission associated with the absence of contrast enhancement and T2 hyperintensity on MRI. Flare-free survival, surgery and hospitalizations were compared based on the presence or not of deep remission., Results: Forty-eight consecutive patients were included with a median follow-up of 62 months after anti-TNF-α first administration. Deep remission was observed in 16 patients (33.4%). For patients in deep remission, the median time to any perianal event was 116 months (95-130) versus 42 months (8-72) in patients with pathological MRI (p < 0.001). Sixteen patients (50%) with pathological MRI had perianal surgery versus 2 (12.5%) in the deep remission group (p < 0.05). The mean duration of cumulative hospital stays was 0.75 ± 0.52 days in the deep remission group versus 19.7 ± 7.4 in the pathological group (p < 0.05)., Conclusions: Higher flare-free survival and lower rates of surgery and hospitalization were found in patients achieving deep remission., (Copyright © 2018.

Abstract

Purpose: To screen all treatments tested for solitary rectal ulcer syndrome (SRUS) without rectal prolapse and to assess their efficacy., Method: A systematic review was performed according to the PRISMA guidelines, focusing on the treatment of SRUS without rectal prolapse. The types of treatment and their efficacy were collected and critically assessed., Results: A selection of 20 studies among the 470 publications focusing on SRUS provided suitable data for a total of 516 patients. Only 2 studies were randomised prospective trials that focused on argon plasma treatment. The mean follow-up was 21.8 months and ranged from 0.25 to 90 months. Most of the studies focused on surgery, including rectopexy, stapled transanal rectal resection, excision of the ulcer, the Delorme procedure, proctectomy, low anterior resection, and ostomy. Populations of the studies were heterogeneous and selected outcomes were specific (failure of medical or surgical treatment). Conservative treatment (high-fibre diet, laxatives, change of defecatory habits, and biofeedback treatment) induced a symptomatic improvement in 71/91 patients (63.6%) and healing of mucosal lesion in 17/51 patients (33.3%). Surgeries (all types) improved SRUS in 77% (54-100%) of patients. Argon plasma coagulation is a promising technique but longer follow-up is necessary., Conclusions: The general quality of the studies focusing on the treatment of SRUS was poor due to the heterogeneity of the population, the sample size of the cohorts, and the heterogeneity of efficacy assessments. The therapeutic approach appears to be multimodal and multidisciplinary and validated in centres of expertise. Further studies evaluating multimodal strategies are needed.

Abstract

Converging evidence suggests that psychosis emerges from the complex interaction of genetic and environmental factors. Stressful life events (SLEs) play a prominent role in combination with coping strategies and with a dysfunctional hypothalamus-pituitary-adrenal axis (HPAA). It has been proposed that the framework of schizotypy might help disentangle the interaction between genetic and environmental factors in the pathogenesis of psychosis. Similarly, 22q11.2 deletion syndrome (22q11DS) is considered as a genetic model of psychosis vulnerability. However, SLE and coping strategies remain largely unexplored in 22q11DS. Moreover, the HPAA has not been systematically investigated in this population. Here, we explored the correlation between SLE, emotional coping strategies, schizotypal personality traits, subthreshold psychotic symptoms in a sample of 43 healthy controls (HCs) compared with 59 individuals with 22q11DS. In the latter, we also explored the correlation with pituitary volume as estimated from structural magnetic resonance imaging. We found that SLE and negative coping strategies were correlated with schizotypal personality traits in both HCs and 22q11DS, and with psychotic symptoms in the 22q11DS group only, whereas reduced pituitary volume correlated with general psychopathology. Moreover, dysfunctional coping mediated the effect of SLE on schizotypal personality traits and psychotic symptoms in 22q11DS. Our findings recapitulate evidence in nonsyndromic patients and confirm the central role of stress and coping in the pathogenesis of psychosis. More broadly, they highlight the importance of environmental factors in the pathway to psychosis in 22q11DS, suggesting a strong rationale for the implementation of stress and particularly coping-oriented interventions in this population.
