RESUMO
The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of inflammatory bowel disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the general principles of surgical treatment of inflammatory bowel disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

INTRODUCTION: Patient safety and quality in healthcare are inseparable. Examining patient safety culture in staff members contributes to further develop quality in healthcare. In Italy there has been some experience in assessing patient safety culture in staff working in hospital. In this pilot study we explored patient safety culture in public health staff working in Italian Local Health Authorities. METHODS: We carried out a descriptive cross sectional study in four Italian territorial Prevention facilities in Northern Italy. We administrated an adapted Italian version of the US Hospital Survey of Patient Safety Culture to all the staff within these facilities. The survey consisted of 10 dimensions based on 33 items, according to the results of a previous psychometric validation. RESULTS: Seventy per cent of the staff responded to the survey (N = 479). Overall, six out of the 10 dimensions exhibited composite scores of positive response frequency for patient safety culture below 50%. While "communication openness" (65%) was the most developed factor, "teamwork across Units" (37%) was the least developed. The work areas with the highest composite scores were Management and the Public Health Laboratory, while in terms of professional categories, Physicians had the highest scores. Patient safety culture in the staff participating in this study was lower than in hospital staff. DISCUSSION: Our descriptive cross sectional study is the first to be carried out in Preventive medicine settings in Italy. It has clearly indicated the need of improvement. Consequently, several interventions with this aim have been implemented.

BACKGROUND: The number and projections of cancer survivors are necessary to meet the healthcare needs of patients, while data on cure prevalence, that is, the percentage of patients who will not die of cancer by time since diagnosis, are lacking. MATERIALS AND METHODS: Data from Italian cancer registries (duration of registration ranged from 9 to 40 years, with a median of 22 years) covering 47% of the population were used to calculate the limited-duration prevalence, the complete prevalence in 2018, projections to 2030, and cure prevalence, by cancer type, sex, age, and time since diagnosis. RESULTS: A total of 3 347 809 people were alive in Italy in 2018 after a cancer diagnosis, corresponding to 5.6% of the resident population. They will increase by 1.5% per year to 4 012 376 in 2030, corresponding to 6.9% of the resident population, 7.6% of women and â¼22% after age 75 years. In 2030, more than one-half of all prevalent cases (2 million) will have been diagnosed by ≥10 years. Those with breast (1.05 million), prostate (0.56 million), or colorectal cancers (0.47 million) will be 52% of all prevalent patients. Cure prevalence was 86% for all patients alive in 2018 (87% for patients with breast cancer and 99% for patients with thyroid or testicular cancer), increasing with time since diagnosis to 93% for patients alive after 5 years and 96% after 10 years. Among patients who survived at least 5 years, the excess risk of death (1 - cure prevalence) was <5% for patients with most cancer types except for those with cancers of the breast (8.3%), lung (11.1%), kidney (13.2%), and bladder (15.5%). CONCLUSIONS: Study findings encourage the implementation of evidence-based policies aimed at improving long-term clinical follow-up and rehabilitation of people living after cancer diagnosis throughout the course of the disease. Updated estimates of complete prevalence are important to enhance data-driven cancer control planning.

BACKGROUND: PCB carcinogenicity to humans is still controversial. Cohort mortality studies in PCB-exposed workers reported elevated risks for the following causes of death: liver, stomach, digestive, brain, prostate cancers and non-Hodgkin lymphoma. OBJECTIVES: The purpose of this study was to update as of December 2006 the mortality experience of two Italian cohorts of workers employed in the manufacture of capacitors impregnated with PCBs. METHODS: Age-gender-and calendar period adjusted Standardized Mortality Ratios (SMRs) and 95% Confidence Intervals (CI) were calculated using regional rates. Analyses by duration of employment and time since first employment were performed Results: Vital status was ascertained for 98.9% of the study subjects. Mortality from biliary tract cancer among males (SMR 3.91; 95%CI 1.47-10.41), digestive cancer "not otherwise specified" in the whole cohort (SMR 2.54; 95%CI 1.21-5.34), and brain cancer in Plant I (SMR 2.13; 95%CI 1.02-4.48), were significantly increased. Increased risks were also observed for Hodgkin's and non-Hodgkin lymphoma. No linear associations between mortality and duration of employment or latency were observed for these cancers. Mortality from stomach cancer did not differ from expectation in the whole cohort, however an increasing risk with increasing duration of employment was detected (p for trend=0.02). CONCLUSIONS: The current update suggests possibly increased cancer risks in PCB-exposed workers, affecting in particular the digestive system, brain, and lymphohemopoietic tissue. However the limited sample size, the lack of clear trends with duration of employment or with latency period, preclude to derive definite conclusions about PCB exposure and the increased cancer risks.

BACKGROUND: In patients with active Crohn's disease (CD), treatment of intra-abdominal abscess usually comprises antibiotics and radiologically guided percutaneous drainage (PD) preceding surgery. The aim of this study was to investigate the risk of postoperative complications and identify the optimal time interval for surgical intervention after PD. METHODS: A multicentre, international, retrospective cohort study was carried out. Details of patients with diagnosis of CD who underwent ultrasonography- or CT-guided PD were retrieved from hospital records using international classification of disease (ICD-10) diagnosis code for CD combined with procedure code for PD. Clinical variables were retrieved and the following outcomes were measured: 30-day postoperative overall complications, intra-abdominal septic complications, unplanned intraoperative adverse events, surgical-site infections, sepsis and pathological postoperative ileus, in addition to abscess recurrence. Patients were categorized into three groups according to the length of the interval from PD to surgery (1-14 days, 15-30 days and more than 30 days) for comparison of outcomes. RESULTS: The cohort comprised 335 CD patients with PD followed by surgery. Median age was 33 (i.q.r. 24-44) years, 152 (45.4 per cent) were females, and median disease duration was 9 (i.q.r. 3.6-15) years. Overall, the 30-day postoperative complications rate was 32.2 per cent and the mortality rate was 1.5 per cent. After adjustment for co-variables, older age (odds ratio 1.03 (95 per cent c.i. 1.01 to 1.06), P < 0.012), residual abscess after PD (odds ratio 0.374 (95 per cent c.i. 0.19 to 0.74), P < 0.014), smoking (odds ratio 1.89 (95 per cent c.i. 1.01 to 3.53), P = 0.049) and low serum albumin concentration (odds ratio 0.921 (95 per cent c.i. 0.89 to 0.96), P < 0.001) were associated with higher rates of postoperative complications. A short waiting interval, less than 2 weeks after PD, was associated with a high incidence of abscess recurrence (odds ratio 0.59 (95 per cent c.i. 0.36 to 0.96), P = 0.042). CONCLUSION: Smoking, low serum albumin concentration and older age were significantly associated with postoperative complications. An interval of at least 2 weeks after successful PD correlated with reduced risk of abscess recurrence.

OBJECTIVE: In mice, a subpopulation of gut dendritic cells (DCs) expressing CD103 drives the development of regulatory T (T(reg)) cells. Further, it was recently described that the cross-talk between human intestinal epithelial cells (IECs) and DCs helps in maintaining gut immune homeostasis via the induction of non-inflammatory DCs. In this study, an analysis was carried out to determine whether IECs could promote the differentiation of CD103+ tolerogenic DCs, and the function of primary CD103+ DCs isolated from human mesenteric lymph nodes (MLNs) was evaluated. METHODS: Monocyte-derived DCs (MoDCs) and circulating CD1c+ DCs were conditioned or not with supernatants from Caco-2 cells or IECs isolated from healthy donors or donors with Crohn's disease and analysed for their ability to induce T(reg) cell differentiation. In some cases, transforming growth factor beta (TGFbeta), retinoic acid (RA) or thymic stromal lymphopoietin (TSLP) were neutralised before conditioning. CD103+ and CD103- DCs were sorted by fluorescence-activated cell sorting (FACS) from MLNs and used in T(reg) cell differentiation experiments. RESULTS: It was found that human IECs promoted the differentiation of tolerogenic DCs able to drive the development of adaptive Foxp3+ T(reg) cells. This control was lost in patients with Crohn's disease and paralleled a reduced expression of tolerogenic factors by primary IECs. MoDCs differentiated with RA or IEC supernatant upregulated the expression of CD103. Consistently, human primary CD103+ DCs isolated from MLNs were endowed with the ability to drive T(reg) cell differentiation. This subset of DCs expressed CCR7 and probably represents a lamina propria-derived migratory population. CONCLUSIONS: A population of tolerogenic CD103+ DCs was identified in the human gut that probably differentiate in response to IEC-derived factors and drive T(reg) cell development.

BACKGROUND AND AIMS: The aim of this study was to report a multicentric experience of segmental colectomy [SC] in ulcerative colitis [UC] patients without active colitis, in order to assess if SC can or cannot represent an alternative to ileal pouch-anal anastomosis [IPAA]. METHODS: All UC patients undergoing SC were included. Postoperative complications according to ClavienDindo's classification, long term results, and risk factors for postoperative colitis and reoperation for colitis on the remnant colon, were assessed. RESULTS: A TOTAL OF: 72 UC patients underwent: sigmoidectomy [n = 28], right colectomy [n = 24], proctectomy [n = 11], or left colectomy [n = 9] for colonic cancer [n = 27], 'diverticulitis' [n = 17], colonic stenosis [n = 5], dysplasia or polyps [n = 8], and miscellaneous [n = 15]. Three patients died postoperatively and 5/69 patients [7%] developed early flare of UC within 3 months after SC. After a median followup of 40 months, 24/69 patients [35%] were reoperated after a median delay after SC of 19 months [range, 2-158 months]: 22/24 [92%] underwent total colectomy and ileorectal anastomosis [n = 9] or total coloproctectomy [TCP] [n = 13] and 2/24 [8%] an additional SC. Reasons for reoperation were: colitis [n = 14; 20%], cancer [n = 3] or dysplasia [n = 3], colonic stenosis [n = 1], and unknown reasons [n = 3]. Endoscopic score of colitis before SC was Mayo 23 in 5/5 [100%] patients with early flare vs 15/42 without early flare [36%; p = 0.0101] and in 9/12 [75%] patients with reoperation for colitis vs 11/35 without reoperation [31%; p = 0.016]. CONCLUSIONS: After segmental colectomy in UC patients, postoperative early colitis is rare [7%]. Segmental colectomy could possibly represent an alternative to IPAA in selected UC patients without active colitis.

BACKGROUND AND AIM: Mucosal healing (MH) after short-term medical treatment is being considered as an important step in the therapeutic work-up of inflammatory bowel disorder (IBD) patients due to the potential prognostic role of MH in predicting disease outcome. However, IBD patients are reluctant to be re-endoscoped during follow-up; therefore, there is a need for non-invasive alternative index of MH which can replace endoscopy in clinical practice. We evaluated bowel ultrasound (US) as a surrogate of colonoscopy in a series of consecutive patients with active ulcerative colitis (UC). PATIENTS AND METHODS: 83 patients with moderate to severe UC requiring high-dose steroids were initially recruited; endoscopic severity of UC was graded 0-3 according to Baron score, and US severity was also graded 0-3 according to the colonic wall thickening and the presence of vascular signal at power Doppler. 74 patients responsive to steroids and then maintained on 5-ASA compounds were followed up with repeated colonoscopy and bowel US at 3, 9 and 15 months from entry. Concordance between clinical, endoscopic and US scores at various visits was determined by kappa statistics. Multiple unconditional logistic regression models were used to assess the predictivity of Truelove, Baron and US scores measured at 3 and 9 months on the development of a UC relapse (Baron score 2-3) at 15 months. RESULTS: An inconsistent concordance was found over time between 0 and I Baron scores and Truelove score (weighted kappa between 0.38 and 0.94), with high and consistent concordance between 0 and I Baron scores and US scores (weighted kappa between 0.76 and 0.90). On logistic regression analysis, a moderate/severe Baron score, regardless of their Truelove score, at 3 months was associated with a high risk of endoscopic activity at 15 months (OR 5.2; 95% CI: 1.6-17.6); similarly, patients with severe US scores (2-3) at 3 months had a high risk of severe endoscopic activity at 15 months (OR 9.1; 95% CI: 2.5-33.5). DISCUSSION: In expert hands bowel US may be used as a surrogate of colonoscopy in evaluating the response to high-dose steroids in severe forms of UC. US score after 3 months of steroid therapy accurately predicts clinical outcome of disease at 15 months.

BACKGROUND AND AIMS: Although laparoscopy is associated with a reduction in adhesions, no data are available about the risk factors for small bowel obstruction [SBO] after laparoscopic ileal pouch-anal anastomosis [IPAA]. Our aims here were to identify the risk factors for SBO after laparoscopic IPAA for inflammatory bowel disease [IBD]. METHODS: All consecutive patients undergoing laparoscopic IPAA for IBD in four European expert centres were included and divided into Groups A [SBO during follow-up] and B [no SBO]. RESULTS: From 2005 to 2015, SBO occurred in 41/521 patients [Group A; 8%]. Two-stage IPAA was more frequently complicated by SBO than 3- and modified 2-stage IPAA [12% vs 7% and 4%, p = 0.04]. After multivariate analysis, postoperative morbidity (odds ratio [OR] = 3, 95% confidence interval [CI] = 1.5-7, p = 0.002), stoma-related complications [OR = 3, 95% CI = 1-6, p = 0.03] and long-term incisional hernia [OR = 6, 95% CI = 2-18, p = 0.003] were predictive factors for SBO, while subtotal colectomy as first surgery was an independent protective factor [OR = 0.4, 95% CI = 0.2-0.8, p = 0.002]. In the subgroup of patients receiving restorative proctocolectomy as first operation, stoma-related or other surgical complications and long-term incisional hernia were predictive of SBO. In the patient subgroup of subtotal colectomy as first operation, postoperative morbidity and long-term incisional hernia were predictive of SBO, whereas ulcerative colitis and a laparoscopic approach during the second surgical stage were protective factors. CONCLUSIONS: We found that SBO occurred in less than 10% of patients after laparoscopic IPAA. The study also suggested that modified 2-stage IPAA could potentially be safer than procedures with temporary ileostomy [2- and 3-stage IPAA] in terms of SBO occurrence.

Purpose To explore patient safety culture among Romanian staff, using the U.S. Hospital Survey on Patient Safety Culture (HSOPSC). MATERIAL AND METHODS: A cross-sectional study was carried out in six hospitals, located in four Romanian regions (Craiova, Cluj-Napoca, Bucharest and Brasov), based on staff census in the Units/hospitals which volunteered to participate in the study (N=1,184). The response rate was 84%. The original questionnaire designed by the American Agency for Healthcare Research and Quality was translated into Romanian (with back translation), pre-tested before application and psychometrically checked. It consists of 42 questions grouped in 12categories, covering multiple aspects of patient safety culture (dimensions). Percentages of positive responses (PPRs) by question and category were analyzed overall and by staff profession. RESULTS: Most respondents were nurses (69%). The main work areas were surgery (24%) and medicine (22%). The highest PPRs were for Supervisor/Manager Expectations & Actions Promoting Safety (88%), Teamwork Within Units (86%), Handoffs and Transitions (84%), Organizational Learning-Continuous Improvement (81%), Overall Perceptions of Safety (80%), Feedback & Communication About Error (75%). The lowest PPRs were for: Staffing (39%), Frequency of Events Reported (59%) and Non-punitive Response to Errors (61%). Nurses exhibited significantly higher PPRs than doctors. CONCLUSIONS: This small-scale study of staff's attitude towards patient safety in Romanian hospitals suggests that there is room for future improvement, especially within the doctor category. Further research should assess the relationship between patient safety culture and frequency of adverse events.
RESUMO
OBJECTIVE: To determine the prevalence of cytomegalovirus infection in patients with steroid-refractory ulcerative colitis who required colonic resection, and to assess its possible association with the use of immunosuppressive and steroid treatment and outcome after colectomy. PATIENTS AND METHODS: The study included surgical specimens and related pre-operative endoscopic biopsy specimens of 77 consecutive ulcerative colitis patients (34 females) who underwent colectomy because of intractable steroid-refractory ulcerative colitis (55 patients), toxic megacolon (6 patients), dysplasia or cancer (7 patients) or loss of function of the colon (9 patients). Clinical features and current and past treatments were analysed. Haematoxylin and eosin and specific immunohistochemical staining for cytomegalovirus were used to detect inclusion bodies in all specimens. RESULTS: Cytomegalovirus infection was found in 15 of 55 steroid-refractory ulcerative colitis patients (27.3%) and in 2 of 22 non-refractory patients (9.1%) (p=0.123). Only six patients had positive staining for cytomegalovirus in pre-operative endoscopic biopsy specimens. Detection of cytomegalovirus inclusion in biopsy specimens was not related to the number of biopsies or to time that had elapsed since colonoscopy and index surgery. Cytomegalovirus-positive patients were more likely to be on systemic corticosteroids (p=0.03). In contrast, current use and duration of immunosuppressive treatment, number of steroid cycles since diagnosis and in the last year, as well as chronic use of steroid in the last year were not significantly related to cytomegalovirus infection. Cytomegalovirus-positive patients did not receive antiviral therapy following proctocolectomy but did not show endoscopic or histological cytomegalovirus reactivation in the ileo-anal pouch and in the remaining bowel. CONCLUSIONS: Cytomegalovirus infection is frequently found in surgical specimens of patients with steroid-refractory ulcerative colitis and is more likely in patients on corticosteroid treatment. Cytomegalovirus infection is frequently unrecognised in pre-operative biopsy specimens, thus raising concerns about the accuracy of the available diagnostic tools. Unrecognised and untreated cytomegalovirus infection does not affect the outcome of ulcerative colitis patients following proctocolectomy.

This study concerned a group of ex-workers (372 males and 99 females) from a firm situated in Bergamo (Italy) that ceased its activity at the beginning of the Nineties. From an introductory analysis of the results, we found out that there isn't excess in the death-rate for liver and bile ducts cancers among the males of this group. Among them, for what concerns the other tumoral pathologies, such as leukaemia and stomach tumors, the information allowed to verify an excess of mortality. However, this increase hasn't result statistically significant. On the contrary, it came out that there is an excess of risk for intestine tumors: standardized death-rate of 2.58. In accordance with the information collected, for the future it will be necessary to carefully examine the research in order to verify the existence of a direct connection to the exposure at PCB and study the incidence (not only for mortality) of these neoplasms.

BACKGROUND: Although bowel ultrasound is a widely accepted diagnostic tool in bowel diseases, its value as the primary imaging procedure in patients with symptoms/signs suggestive of inflammatory bowel disorders is still unclear. AIM: To investigate the accuracy of bowel ultrasound compared with barium X-ray studies, computed tomography, endoscopy and bowel surgery in the initial assessment of inflammatory bowel disorders. METHODS: Four hundred and eighty-seven patients hospitalized consecutively for symptoms or signs suggestive of a bowel disorder between December 1999 and March 2002 were initially enrolled in the study. All patients underwent bowel ultrasound as the first imaging procedure within 36 h of admission; radiographic evaluations, endoscopy and/or surgery were then performed as appropriate and the results of these investigations were used as the gold standard. RESULTS: Three hundred and thirty-six patients had pathological findings of the bowel detectable at ultrasound as the final diagnosis. The main organic disorders found were Crohn's disease (56%), ulcerative/indeterminate colitis (30%), bowel tumours (5%), appendicitis/diverticulitis (2%) and other inflammatory conditions (8%). The overall sensitivity and specificity of bowel ultrasound were 85% and 95%, respectively, whereas the positive and negative predictive values were 98% and 75%, respectively. Comparisons of ultrasound with X-ray or endoscopic results by disease localization showed that the diagnostic performance of ultrasound was higher for inflammatory conditions of the ileum and sigmoid/descending colon (sensitivity of 92% and 87%, respectively), whereas abnormalities localized in the rectum, duodenum and proximal jejunum were often missed by ultrasound. CONCLUSIONS: In expert hands, bowel ultrasound is highly predictive of inflammatory disease localized in the ileum or colon, and may well be used as the primary imaging method when Crohn's disease or ulcerative colitis is suspected on a clinical basis.

AIM: To establish whether intestinal ultrasound, clinical or biochemical indices of activity can assess histological features of ileal stenosis in Crohn's disease. METHODS: In 43 patients undergoing surgery for a single ileal stenosis, clinical and biochemical parameters, as well as intestinal ultrasound, were assessed prior to surgery. The echo pattern of thickened bowel segments at the site of stenosis was classified as hypoechoic, stratified or mixed (segments with/without stratification). During surgery, stenoses were identified, resected and then histologically examined using standardized criteria. RESULTS: Clinical and biochemical indices of activity showed an overall weak positive correlation with histological inflammatory parameters and a negative correlation with fibrosis. The intestinal ultrasound echo pattern at the stenosis site was stratified in 25 patients, hypoechoic in 14 and mixed in four. Stenoses characterized by a stratified echo pattern showed a significantly higher degree of fibrosis, those characterized by hypoechoic echo pattern showed a higher degree of inflammation, while stenoses with a mixed echo pattern showed high degrees of both fibrosis and inflammation. CONCLUSION: Ultrasound and, to a lesser degree, clinical and laboratory indices discriminate between inflammatory and fibrotic ileal stenoses complicating Crohn's disease, thus allowing appropriate medical and/or surgical treatment to be defined.
