Three-row versus two-row circular staplers for left-sided colorectal anastomosis: a propensity score-matched analysis of the iCral 2 and 3 prospective cohorts

Background: Since most anastomoses after left-sided colorectal resections are performed with a circular stapler, any technological change in stapling devices may influence the incidence of anastomotic adverse events. The aim of the present study was to analyze the effect of a three-row circular stapler on anastomotic leakage and related morbidity after left-sided colorectal resections. Materials and methods: A circular stapled anastomosis was performed in 4255 (50.9%) out of 8359 patients enrolled in two prospective multicenter studies in Italy, and, after exclusion criteria to reduce heterogeneity, 2799 (65.8%) cases were retrospectively analyzed through a 1:1 propensity score-matching model including 20 covariates relative to patient characteristics, to surgery and to perioperative management. Two well-balanced groups of 425 patients each were obtained: group (A) – true population of interest, anastomosis performed with a three-row circular stapler; group (B) – control population, anastomosis performed with a two-row circular stapler. The target of inferences was the average treatment effect in the treated (ATT). The primary endpoints were overall and major anastomotic leakage and overall anastomotic bleeding; the secondary endpoints were overall and major morbidity and mortality rates. The results of multiple logistic regression analyses for the outcomes, including the 20 covariates selected for matching, were presented as odds ratios (OR) and 95% confidence intervals (95% CI). Results: Group A versus group B showed a significantly lower risk of overall anastomotic leakage (2.1 vs. 6.1%; OR 0.33; 95% CI 0.15–0.73; P = 0.006), major anastomotic leakage (2.1 vs. 5.2%; OR 0.39; 95% CI 0.17–0.87; P = 0.022), and major morbidity (3.5 vs. 6.6% events; OR 0.47; 95% CI 0.24–0.91; P = 0.026). Conclusion: The use of three-row circular staplers independently reduced the risk of anastomotic leakage and related morbidity after left-sided colorectal resection. Twenty-five patients were required to avoid one leakage

The impact of synchronous liver resection on the risk of anastomotic leakage following elective colorectal resection. A propensity score match analysis on behalf of the iCral study group

Introduction: how best to manage patients with colorectal cancer and synchronous liver metastasis is still controversial, with specific concerns of increased risk of postoperative complications following combined resection. We aimed at analyzing the influence of combined liver resection on the risk of anastomotic leak (AL) following colorectal resection. Methods: we reviewed the iCral prospectively maintained database to compare the relative risk of AL of patients undergoing colorectal resection for cancer to that of patients receiving simultaneous liver and colorectal resection for cancer with isolated hepatic metastases. The incidence of AL was the primary outcome of the analysis. Perioperative details and postoperative complications were also appraised. Results: out of a total of 996 patients who underwent colorectal resection for cancer, 206 receiving isolated colorectal resection were compared with a matched group of 53 patients undergoing simultaneous liver and colorectal resection. Combined surgery had greater operative time and resulted in longer postoperative hospitalization compared to colorectal resection alone. The proportion of overall morbidity following combined resection was significantly higher than after isolated colorectal resection (56.6% vs. 37.9%, p = 0.021). Overall, the two groups of patients did not differ neither on the rate of major postoperative complications, nor in terms of AL (9.4% vs. 6.3%, p = 0.381). At specific multivariate analysis, the duration of surgery was the only risk factor independently associated with the likelihood of AL. Conclusions: combining hepatic with colorectal resection for the treatment of synchronous liver metastasis from colorectal cancer does not increase significantly the incidence of AL

Non-bullous Impetigo: Incidence, Prevalence, and Treatment in the Pediatric Primary Care Setting in Italy

Impetigo is a common skin infection in children. The worldwide prevalence in children is estimated to be 12%, but this may be lower since high-income countries are under-represented. This research aims to evaluate the incidence, prevalence, and management of children with non-bullous impetigo (NBI) residing in Italy. This retrospective cohort study included children up to 14 years of age enrolled in the Pedianet database from January 2004 to June 2018. Events were identified searching ICD9-CM codes (684 and 694.3) and free text fields for a diagnosis of NBI reported during a primary care visit. Diagnoses were manually validated, and events registered within 30-days after the index date were considered follow-ups. Incidence (IR) and prevalence (PR) rates of NBI were stratified by sex, age group, and calendar year. Topical and systemic antibiotic treatments were grouped based on ATC codes. 15,136 NBI episodes occurred in a total cohort of 225,979 children. The overall IR of NBI was 9.5 per 1,000 person-years, and children aged 1–4 years had the highest IR (13.2 per 1,000 person-years). A significant decrease in NBI IR from 13 per 1,000 person-years in 2004 to 7.46 per 1,000 person-years in 2018 (p < 0.0001) was noted. Most of the episodes were treated; systemic antibiotics were preferred over topical. Conclusion: The prevalence of NBI in children in Italy is less than one third than the global estimate and the trend in time is decreasing. Over prescriptions of systemic antibiotics pose a threat to the diffusion of antimicrobial resistance

Reduction of risk factors for cardiovascular diseases in morbid-obese patients following biliary-intestinal bypass: 3 years' follow-up

BACKGROUND: Obese patients are often affected by hypertension, dyslipidaemia, impaired glucose metabolism, and suffer from cardiovascular disease (CVD), related to the characteristic metabolic alterations. AIM OF THE STUDY: To evaluate reduction of risk factors for CVDs in morbid-obese patients ( body mass index (BMI) 440 kg/m(2)) after weight loss upon bariatric surgery intervention of biliary-intestinal bypass. SUBJECTS: 45 (17 men, 28 women) morbid-obese patients (age: 19-49 y, BMI>40 kg/m(2)). All patients were selected on the basis of medical history, physical and biochemical evaluation and of psychiatric tests, which were performed on all individuals admitted to our Day Hospital to verify the safety of surgical intervention. MEASUREMENTS: Body weight, body composition (by dual X-ray absorptiometry, DXA), blood pressure, lipid profile, fibrinogen and glucose metabolism were monitored at baseline and 1, 3, 6, 9, 12, 24 and 36 months after surgery. RESULTS: A significant and persistent weight loss was present in all patients at the end of the 3 y follow-up period (P<0.001), with a progressive reduction of total and trunk fat mass as evaluated by means of DXA. Additionally, a parallel significant reduction in systolic (P<0.001) and diastolic (P<0.001) blood pressure was observed. Total and LDL cholesterol were significantly reduced (P<0.001), while HDL showed no modifications; triglycerides declined progressively during the 3 y follow-up (P<0.001). Fibrinogen decreased from 364.5&PLUSMN;82.4 to 266.4&PLUSMN;45.7 mg/dl at the end of the period (P<0.001). Fasting glucose levels and glucose levels 120 min after an oral glucose tolerance test were reduced from 95.1720.3 to 78.679.1 mg/dl (P<0.001) and from 116.9&PLUSMN;34.7 to 77.6&PLUSMN;15.5 mg/dl (P<0.001), respectively, at baseline and at the end of the study. Moreover, fasting insulin decreased from 30.0720.4 to 8.672.9 muUI/ml (P<0.001) after 3 y, while insulin levels after ( 120 min) oral glucose load decreased from 105.5761.5 to 12.076.0 &mu;UI/ml (P<0.001). CONCLUSION: Our results show that biliary-intestinal bypass may represent a valid and alternative therapeutic approach in patients with morbid obesity since it induces a significant and stable reduction of body weight and obesity-related risk factors for CVD
