Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Comparison of adjustable continence therapy periurethral balloons and artificial urinary sphincter in female patients with stress urinary incontinence due to intrinsic sphincter deficiency

International audienceIntroduction and hypothesis - The objective was to compare the outcomes of the ACT® device with those of the artificial urinary sphincter (AUS) AMS 800 in the treatment of stress urinary incontinence (SUI) due to sphincter deficiency in women.Methods - All the women who underwent surgical treatment for SUI due to intrinsic sphincter deficiency from 2007 to 2017 were included in a single-center retrospective study. The primary endpoint was the functional outcome. Perioperative functional parameters of the two groups were compared.Results - Twenty-five patients underwent an ACT® implantation and 36 an AUS implantation. Patients in the AUS group were younger (62.9 vs 70.4 years; p = 0.03) with less comorbidity (ASA Score = 3 in 12.1% vs 33.3%; p = 0.005). Operative time and hospital stay were shorter in the ACT® group (45.7 vs 206.1 min; p Conclusions - In the present series, keeping in mind the significantly different baseline characteristics, AUS implantation was associated with better functional outcomes than the ACT® in female patients with SUI due to intrinsic sphincter deficiency, but with a higher intraoperative complications rate, longer operative time, and a longer stay.<br

The Changing Face of Artificial Urinary Sphincter Use in France The Future is Female

International audienceAnalyzing concurrently data from the manufacturer and from a national comprehensive administrative claim database (PMSI)we found that, overall, the total number of AUS implanted (male+female) increased from 2012 to 2017 (+8.8%). This growth was driven by a strong increase in the number of female implants from 2015 to 2017 (+28.9%). Meanwhile, the number of AUS implanted in male patients remained roughly stable and the total number of anti-incontinence surgery in men (slings+AUS) decreased steadily over the period studied

A piglet model of iatrogenic rectosigmoid hypoganglionosis reveals the impact of the enteric nervous system on gut barrier function and microbiota postnatal development

International audienceBackground - Hirschsprung-associated enterocolitis physiopathology likely involves disturbed interactions between gut microbes and the host during the early neonatal period. Our objective was to create a neonatal porcine model of iatrogenic aganglionosis to evaluate the impact of the enteric nervous system (ENS) on microbiota and intestinal barrier postnatal development. Methods - Under general anesthesia, the rectosigmoid serosa of 5-day-old suckling piglets was exposed to 0.5% benzalkonium chloride solution (BAC, n = 7) or saline (SHAM, n = 5) for 1 h. After surgery, animals returned to their home-cage with the sow and littermates and were studied 21 days later. Results - BAC treatment induced partial aganglionosis with absence of myenteric plexus and reduced surface area of submucosal plexus ganglia (-58%, P < 0.05) in one third of the rectosigmoid circumference. Epithelial permeability of this zone was increased (conductance +63%, FITC-dextran flux +386%, horseradish-peroxidase flux +563%, P < 0.05). Tight junction protein remodeling was observed with decreased ZO-1 (-95%, P < 0.05) and increased claudin-3 and e-cadherin expressions (+197% and 61%, P < 0.05 and P = 0.06, respectively). BAC piglets harbored greater abundance of proinflammatory bacteria (Bilophila, Fusobacterium) compared to SHAM in the rectosigmoid lumen. Conclusions - This large animal model demonstrates that hypoganglionosis is associated with dramatic defects of gut barrier function and establishment of proinflammatory bacteria. Level of evidence

Defecation disorders in Spina Bifida Realistic goals and best therapeutic approaches

International audienceAims - Spina Bifida (SB) is a rare congenital condition that frequently impairs the neurological control of both fecal continence and defecation. Several therapeutic strategies have been proposed but impact assessment is lacking. Our objectives were to quantify the symptomatic improvement and to determine the optimal strategy in this rare condition where randomized controlled trials are difficult to conduct. Methods - Data were extracted from a prospective database. The present analysis focused on patients having undergone at least two gastroenterological assessments. A standardized therapeutic approach was used from the first visit. Improvement was quantified by the variation of quantified symptomatic scores. Results - The data of of 57 adults with SB (gender F/M: 30/27 [52.6/47.4%]; mean age: 33.8 [18.5] years) were extracted. After a mean follow-up of 46 months, 23/57 patients (40.4%) had at least improvement of one point of the Cleveland Clinic Incontinence score (CCIS); 13/57 (22.8%) reported a significant improvement of continence (delta score >50%). Five of the twelve patients (41.6%) with CCIS < 5 at baseline became incontinent over time. The neurological level was not associated with a worse continence outcome. Work on stool consistency and transanal irrigation were the most useful strategies in those with significant improvement of continence. Conclusions - Using conventional strategies, a benefit on fecal continence occurs in only one out of five patients suffering from Spina Bifida and continent patients at baseline can develop fecal incontinence over time. A strategy targeting improved control of defecation (transanal irrigation) and a standardization of follow-up protocol might be beneficial

Risk factors for stress urinary incontinence recurrence after midurethral sling revision

International audienceObjectivesThe purpose of this study was to report the rate of stress urinary incontinence (SUI) recurrence after sling revision, and to determine predictive factors of SUI recurrence.MethodsWe conducted a retrospective cohort study in a single academic center between 2005 and 2022, of patients who underwent sling revision. Four surgical techniques were used for sling revision (loosening, section, partial, and total excision). The primary endpoint was recurrence of SUI at 3 months postoperatively, and the other outcome of interest was the rate of subsequent anti-incontinence surgical procedure.ResultsSixty-nine patients were included for analysis. SUI recurred in 46.4% of patients. Fifteen patients underwent a subsequent anti-incontinence procedure (21.8%). The time to revision was significantly longer in the group with recurrent SUI (median: 84.5 vs. 44.8 months; p = 0.004). The recurrence rate differed significantly depending on the revision technique: 7.7% after sling loosening, 22.2% after sling section, 60% after partial excision, and 66.7% after complete sling removal (p = 0.001). The risk of SUI recurrence was lower for those whose indication of reoperation was voiding dysfunction (27.3% vs. 66.7%; p = 0.002), and was higher for those who underwent a trans-obturator tap rather than a tension-free vaginal tape revision (68.4% vs. 35.7%; p = 0.02). In multivariate analysis, only the revision technique remained significantly associated with the risk of recurrence of SUI (complete excision vs. section: odds ratio = 4.66; p = 0.04).ConclusionThe risk of SUI recurrence may differ widely according to the techniques used, and it seems that the less extensive the surgical procedure is, the lower the risk is
