    Introduction. Intersigmoid hernia is a hernia of the small bowel into the intersigmoid fossa. It is well known to be a rare condition. Recent reports reveal that the preoperative differentiation of intersigmoid hernias is difficult and the diagnosis is often confirmed during the laparotomic exploration. Due to the vague clinical manifestation in most cases, the surgical treatment is frequently delayed. Materials and Methods. In this study, we systematically reviewed the literature up to 2019 covering 114 studies and 124 patients with an intersigmoid hernia. &e purpose of this work is to improve the understanding of the anatomical aspects, clinical presentation, diagnosis, and treatment of intersigmoid hernia so as to assist the preoperative differentiation of these hernias when presented as acute abdomen in the emergency department. Results. &e diameter of the intersigmoid recess was reported with mean 2.65 cm (range 1–10 cm, SD 1.15 cm) and the length of the incarcerated small intestine was between 3 cm (min) and 150 cm (max): mean 25.25 cm, SD 35.04 cm. &e diameter of the sigmoid recess was greater in patients who underwent resection due to strangulation (mean 3.31 cm, SD 1.53 cm) compared to those who underwent only reduction of the hernia (mean 2.35 cm, SD 0.74 cm). &e time from onset to operation was less in patients undergoing resection surgery due to throttling (mean 3.03 days, SD 3.01 days) compared to those who underwent only a reduction of hernia incarceration (mean 8.49 days, SD 6.83 days). Conclusion. Intersigmoid hernia is often a forgotten diagnosis and a clinical challange due to its anatomical characteristics

    Endocarditis of Native Valve due to Proteus mirabilis: Case Report and Literature Review

    Get PDF
    AbstractEndocarditis due to Proteus mirabilis is very uncommon and the optimal surgical and/or antibiotic treatment is not well defined. Guidelines from the AHA and ESC recommend prolonged courses of combined antibiotic therapy but information regarding the clinical presentation, the choice of treatment, the surgical management, and the duration of therapy can only be taken from clinical cases reported in literature. We describe a case of native valve endocarditis due to Proteus mirabilis, successfully treated with antibiotic therapy alone with a review of the relevant literature on this topic

    Background and Objectives: Surgical Site Infections (SSIs) are the most common healthcare-associated infections and represent a major clinical problem in terms of mortality, morbidity, length of stay and overall costs. The appropriateness of Surgical Antibiotic Prophylaxis (SAP) is a key component to reduce the SSIs while the inappropriateness is a major cause of some emerging infections and selection of antibiotic resistance, therefore increasing healthcare costs. For this reasons international and national guidelines have been developed to guide clinicians in the optimal use of SAP. The The overall compliance to these guidelines is poor, with a high heterogeneity and as a consequence there is no universally recognized intervention to improve the appropriateness of SAP. The antimicrobial stewardship program is a systematic approach to improve appropriateness of antimicrobial use, to optimize the treatment of infections and to minimize the adverse effects associated with antibiotic use, like antimicrobial resistance, toxicity and costs. We describe a successfully Antimicrobial Stewardship (AMS) intervention on SAP appropriateness. Material and Methods: The prospective study was conducted at “Santa Maria” tertiary hospital in Terni, Umbria, in 12 main surgical units and was organized in three subsequent phases . The hospital defined evidence-based guidelines for optimal use of SAP, approved a new workflow to optimize the process of ordering, dispensing, administering and documenting SAP and created a satellite pharmacy in the operative block . Phase 1: we analysed 2059 elective surgical cases from January to June 2018 for 3 SAP parameters of appropriateness: indication, choice, dose. Phase 2: in July 2018 an audit was performed to analyse the result ; we reviewed 1781 elective surgical procedures from July to December 2018 looking for the same 3 SAP parameters of appropriateness. Results: The comparative analysis between phase 1 and 2 has demonstrated that the correct indication has a significant improvement (p-value 0.00128), moving from 73.63% in phase 1 to 77.82% in phase 2. The choice of antibiotic has not shown any significant improvement (p-value 0.4863) . The correct dose significantly improved (p-value< 2.2 1016 ), rising from 71.75% in phase 1 to 86.19% in phase 2. The overall compliance had a significant improvement (p-value <5.6 1012) passing from 40.21% in tphase 1 to 51.15% in phase 2. Conclusions: Our prospective study demonstrated a model of succesfully antimicrobial stewardship intervention that improves appropriateness of SAP

    COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

    IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Background: A genetic origin of cerebrovascular accidents has long been suspected on the basis of epidemiologic evidence and familial aggregation. Nevertheless, the final phenotype is largely influenced by concomitant risk factors. We aimed to investigate whether impairment of endothelium-dependent vasodilation can be used as an informative intermediate vascular phenotype in hypertensive patients with familial history of stroke. Methods: Fourteen hypertensive individuals, seven with familial history of stroke (FH+), seven without familial history of stroke (FH-), and six normotensive volunteers (C) were included in the study. High-resolution ultrasound and Doppler were used to measure radial artery diameter and blood flow at rest, during reactive hyperemia, and after intra-arterial infusion of NG-monomethyl-l-arginine (L-NMMA) to inhibit NO synthase. Results: Basal blood flow and diameter were comparable in all groups. Flow-mediated dilation was impaired in FH+ (3.2% ± 2%), compared with FH- (9.6% ± 1%; P = . 01) and C (15.9% ± 3%; P = . 001). The L-NMMA decreased basal flow in FH- (16.0 ± 2 v 13.8 ± 1 mL/min; P = . 04), and C (23.3 ± 2 v 16.5 ± 2 mL/min, P = .003) but did not exert any significant effect in FH+ subjects (16.4 ± 3 v 15.8 ± 2 mL/min, P = .77). Conclusions: These findings demonstrate that NO bioavailability is reduced in hypertensive subjects with familial history of stroke. Such a phenotype may represent an early marker of susceptibility to cerebrovascular events in this population. © 2006 American Journal of Hypertension, Ltd
