Crossing barriers: the burden of inflammatory bowel disease across Western Europe

Disease burden; Healthcare; Inflammatory bowel diseaseCàrrega de la malaltia; Atenció sanitària; Malaltia inflamatòria de l'intestíCarga de la enfermedad; Atención sanitaria; Enfermedad inflamatoria intestinalAn estimated 2.5–3 million individuals (0.4%) in Europe are affected by inflammatory bowel disease (IBD). Whilst incidence rates for IBD are stabilising across Europe, the prevalence is rising and subsequently resulting in a significant cost to the healthcare system of an estimated 4.6–5.6 billion euros per year. Hospitalisation and surgical resection rates are generally on a downward trend, which is contrary to the rising cost of novel medication. This signifies a large part of healthcare cost and burden. Despite publicly funded healthcare systems in most European countries, there is still wide variation in how patients receive and/or pay for biologic medication. This review will provide an overview and discuss the different healthcare systems within Western Europe and the barriers that affect overall management of a changing IBD landscape, including differences to hospitalisation and surgical rates, access to medication and clinical trial participation and recruitment. This review will also discuss the importance of standardising IBD management to attain high-quality care for all patients with IBD

Macrophages produce and functionally respond to interleukin-34 in colon cancer

In colorectal cancer (CRC), macrophages represent a major component of the tumor mass and exert mostly functions promoting tumor cell survival, proliferation, and dissemination. Interleukin-34 (IL-34) is a cytokine overproduced by colon cancer (CRC) cells and supposed to make a valid contribution to the growth and diffusion of CRC cells. The biological functions of IL-34 are mediated by the macrophage colony-stimulating factor receptor (M-CSFR-1), which controls monocyte/macrophage differentiation, growth, and survival. We here investigated whether, in CRC, tumor-associated macrophages (TAMs) express M-CSFR-1 and functionally respond to IL-34. By flow-cytometry analysis of tumor-infiltrating cells (TICs) and lamina propria mononuclear cells (LPMCs) isolated from normal, adjacent mucosa of CRC patients, we showed that CD68/HLA-DRII-expressing TICs and LPMCs expressed M-CSFR-1. Both these cell types produced IL-34 even though the expression of the cytokine was more pronounced in TICs as compared to normal LPMCs. Moreover, in CRC samples, there was a positive correlation between IL-34-producing cells and CD68-positive cells. Stimulation of LPMCs and TICs with IL-34 resulted in enhanced expression of CD163 and CD206, two markers of type II-polarized macrophages, and this was evident at both RNA and protein level. In the same cell cultures, IL-34 stimulated expression and production of IL-6, a cytokine known to promote CRC cell growth and diffusion. Finally, knockdown of IL-34 in TICs with specific antisense oligonucleotides with: a specific antisesne oligonucleotide decreased IL-6 production and the number of TAMs producing this cytokine. This is the first to show a positive role of IL-34 in the control of TAMs in CRC, further supporting the notion that IL-34 sustains colon tumorigenesis

A narrative on diversity, equity, and inclusion in surgery: insights from the European Society of Coloproctology and identification of points for action

Diversity; Equity; InterviewDiversidad; Equidad; EntrevistaDiversitat; Equitat; EntrevistaThe focus of the 2022 European Society of Coloproctology (ESCP) annual campaign was diversity, equity, and inclusion (DEI) in surgery. The ESCP “Operation Equal Access” campaign sought to interview key-opinion leaders and trainees, to raise awareness on inequalities, inform the community of the status of the topic, and to identify future areas for improvement. The ESCP Social Media Working Group interviewed experts who have made significant contributions to DEI in colorectal surgery and were acknowledged opinion leaders in the field. The interviews focused on their career, professional life, experiences, and opportunities during their training, and their views on DEI in colorectal surgery. DEI principles, education, and values need further promotion to reduce and address bias within the profession and overall improve the experience of minority community including health professionals and patients. International Societies are working to facilitate training opportunities and overcome DEI, and networking have contributed to that. Collaborations between societies will be pivotal to contribute to offering research and leadership opportunities equally. Access to advanced workshops including cadaveric training and simulation can be consistently promoted and provided globally via societies through telemonitoring. Involving patients in research should be encouraged, as it brings the perspective of a living experience.Open access funding provided by Università degli Studi della Campania Luigi Vanvitelli within the CRUI-CARE Agreement

Definition and reporting of lymphadenectomy and complete mesocolic excision for radical right colectomy: a systematic review

Background: Several procedures have been proposed to reduce the rates of recurrence in patients with right-sided colon cancer. Different procedures for a radical right colectomy (RRC), including extended D3 lymphadenectomy, complete mesocolic excision and central vascular ligation have been associated with survival benefits by some authors, but results are inconsistent. The aim of this study was to assess the variability in definition and reporting of RRC, which might be responsible for significant differences in outcome evaluation. Methods: PRISMA-compliant systematic literature review to identify the definitions of RRC. Primary aims were to identify surgical steps and different nomenclature for RRC. Secondary aims were description of heterogeneity and overlap among different RRC techniques. Results: Ninety-nine articles satisfied inclusion criteria. Eight surgical steps were identified and recorded as specific to RRC: Central arterial ligation was described in 100% of the included studies; preservation of mesocolic integrity in 73% and dissection along the SMV plane in 67%. Other surgical steps were inconstantly reported. Six differently named techniques for RRC have been identified. There were 35 definitions for the 6 techniques and 40% of these were used to identify more than one technique. Conclusions: The only universally adopted surgical step for RRC is central arterial ligation. There is great heterogeneity and consistent overlap among definitions of all RRC techniques. This is likely to jeopardise the interpretation of the outcomes of studies on the topic. Consistent use of definitions and reporting of procedures are needed to obtain reliable conclusions in future trials. PROSPERO CRD42021241650.

Preoperative Immunonutrition vs. Standard Dietary Advice in Normo-Nourished Patients Undergoing Fast-Track Laparoscopic Colorectal Surgery

Immunonutrition (IN) appears to reduce infective complications and in-hospital length of stay (LOS) after major gastrointestinal surgery, but its use in normo-nourished patients is still controversial. The primary aim of this comparative observational study was to evaluate if pre-operative IN reduces in-hospital stay in patients undergoing laparoscopic colorectal resection for cancer under an enhanced recovery after surgery (ERAS) program. The influence of IN on time to first bowel movements, time to full oral diet tolerance, number and type of complications, reasons of prolonged LOS and readmission rate was evaluated as secondary outcome. Patients undergoing ERAS laparoscopic colorectal resection between December 2016 and December 2019 were reviewed. Patients who have received preoperative IN (group A) were compared to those receiving standard dietary advice (group B). Mean in-hospital LOS was significantly shorter in patients receiving preoperative IN than standard dietary advice (4.85 ± 2.25 days vs. 6.06 ± 3.95 days; p < 0.0492). No differences in secondary outcomes were observed. Preoperative IN associated with ERAS protocol in normo-nourished patients undergoing laparoscopic colorectal cancer resection seems to reduce LOS

Management of Low Rectal Cancer Complicating Ulcerative Colitis: Proposal of a Treatment Algorithm

Simple SummaryThis article expresses the viewpoint of the authors' management of low rectal cancer in ulcerative colitis (UC). This subject suffers from a paucity of literature and therefore management decision is very difficult to take. The aim of this paper is to provide a structured approach to a challenging situation. It is subdivided into two parts: a first part where the existing literature is reviewed critically, and a second part in which, on the basis of the literature review and their extensive clinical experience, a management algorithm is proposed by the authors to offer guidance to surgical and oncological practices. This text adds to the literature a useful guide for the treatment of these complex clinical scenarios.Low rectal Carcinoma arising at the background of Ulcerative Colitis poses significant management challenges to the clinicians. The complex decision-making requires discussion at the multidisciplinary team meeting. The published literature is scarce, and there are significant variations in the management of such patients. We reviewed treatment protocols and operative strategies; with the aim of providing a practical framework for the management of low rectal cancer complicating UC. A practical treatment algorithm is proposed

Metastatic renal cell carcinoma invading liver, duodenum and ivc, surgical treatment and literature review. A case report

Renal Cell Carcinoma has a biologic predisposition for direct vascular invasion: intravascular tumor thrombus is found in 5% to 20% of the cases inside the renal vein or the inferior vena cava. Despite new and effective conservative therapy such as targeted therapy and immunotherapy, cytoreductive nephrectomy and palliative nephrectomy continues to have an important role in T4 patient. The patient selection for cytoreductive nephrectomy should be done carefully. This report present an unique case of metastatic RCC with invasion of the duodenum, liver and retrohepatic IVC, the adopted surgical approach and a review of the literature. Complete surgical extirpation is possible in cases of RCC invading other organs such as pancreas, duodenum, liver, retroperitoneum and IVC. In this scenario, to narrow the possible intraoperative complication, a multidisciplinary approach and equipe is recommended
