Abstract

Resume Le bilan preoperatoire du cancer colique non metastatique comprend la coloscopie optique (CO) et le scanner thoraco-abdomino-pelvien avec injection de produit de contraste iode. Avec la CO preoperatoire, le siege anatomique de la tumeur peut etre errone en particulier dans les dolichocolons et la recherche de lesions coliques synchrones est limitee lorsque la tumeur est infranchissable. Le scanner permet d’obtenir le bilan d’extension a distance de la tumeur mais reste limite pour le bilan d’extension locoregionale. L’angiocoloscanner 3D (ACS 3D) necessite une preparation colique specifique, une insufflation colique automatique au CO2, et une injection de produit de contraste. L’ACS offre une vision 3D de la morphologie globale du colon et situe precisement le siege de la tumeur colique. La fusion des images du colon avec celles des vaisseaux mesenteriques et coliques permet d’obtenir une representation des variations anatomiques vasculaires. Ces informations pourraient aider le chirurgien a mieux planifier la colectomie. Le recours aux images bidimensionnelles de l’ACS 3D avec des coupes perpendiculaires au grand axe du segment colique ou siege la tumeur permet d’apporter des informations precises sur son extension parietale et etre utile pour discuter de l’interet d’une chimiotherapie neoadjuvante.

Abstract

Background The estimated increase in prevalence of radiation enteropathy associated with a current scarcity of effective treatment options underline the need for the development of new therapies. Extracellular vesicles (EV), which are membrane-bound particles secreted by cells containing proteins, lipids and nucleic acids, have yielded promising preclinical results in various applications in regenerative medicine. Here, we aimed to investigate whether EV from adipose-derived stromal cells (ADSC) may present a therapeutic potential in the context of radiation colitis. Methods EV were produced from primary rat ADSC by exposure to a turbulent flow. Radiation colitis was induced by fractionated irradiation at a dose of 3x10Gy on a colorectal window (3x2cm) in male Sprague-Dawley rats (311-386g) at days 0, 2 and 4; following a pre-established protocol. Treatment was administered at days 11 and 15 through submucosal endoscopic injections of rat ADSC (n=9 rats, 2x106cells per dose), EV (n=9 rats, 1.06x1011 particles per dose), or an equivalent volume of saline (n=10 rats). The rats were sacrificed at day 17. Our primary endpoint was the extent of colonic epithelial injury at histological analysis (Table 1). Secondary endpoints included an endoscopic assessment of the severity of lesions at day 15 (Table 2) and an evaluation of macrophage infiltration in the colonic mucosa by CD68 immunohistochemistry. Comparisons of proportions were performed by the Chi-squared test followed by Fisher’s exact test. Results In the ADSC group, 1 rat died from anaesthesia complications. No other adverse effects were observed. No differences in total body weight evolution were observed between the groups. At day 15, a statistically significant decrease of the proportion of animals with moderate to severe lesions was evidenced by endoscopy in the EV group compared to the saline group (p=0.0031; Figure 1). No differences were observed between the other groups. Histological analysis of the colonic epithelial injury score evidenced a non-significant tendency towards a decreased length of high-grade lesions in the EV group (mean±standard deviation: 9180±3684µm; Figure 2) compared with the saline (11536±2711µm) and ADSC (11636±2815) groups. Similarly, CD68+ macrophage infiltration at the site of colonic mucosal lesions tended to be lower in the EV and ADSC groups compared to the saline group. Conclusion This proof-of-concept study seemed to demonstrate a beneficial effect of locally administered extracellular vesicles for the treatment of radiation colitis in the acute setting. A confirmation study in a larger animal cohort is underway, and further investigations focusing on dose effects or long-term effects on fibrosis are required to complete these preliminary results.

Abstract

Summary The pre-operative work-up for non-metastatic colon cancer includes colonoscopy and thoraco-abdomino-pelvic computed tomography (CT) with intravenous (IV) contrast. Colonoscopic determination of the anatomical location of the tumor may be erroneous, particularly with a long redundant colon (dolichocolon), and the search for synchronous colon neoplasms is limited when the endoscope cannot traverse the tumor-bearing segment. While computed tomography colonography angiography (CTC-A) makes it possible to assess distant tumor metastasis, it remains limited for the assessment of loco-regional extension. CTC-A requires specific colonic preparation, controlled colonic insufflation with CO2, and an injection of IV contrast. CTC-A provides a 3-D view of the overall morphology of the colon and precisely localizes the site of the colonic tumor. Merging the images of the colon with those of mesenteric and colonic vessels provides a representation of anatomical vascular variations. This information could help the surgeon to better plan the colectomy. The use of two-dimensional images of CTC-A with sections perpendicular to the major axis of the tumor-bearing colonic segment can provide precise information on the degree of parietal extension and be useful in evaluating the value of neo-adjuvant chemotherapy.

Abstract

Les tumeurs sous-muqueuses (TSM) de l’estomac sont des lesions frequentes de decouverte souvent fortuite. La plupart des TSM sont asymptomatiques et d’evolution benigne, telles que les lipomes, les leiomyomes, les schwannomes, les pancreas aberrants. Certaines TSM gastriques ont un potentiel de malignite, notamment celles developpees a partir de la musculeuse comme les gastrointestinal stromal tumor et les tumeurs neuroendocrines. Le diagnostic de certitude de ces lesions peut etre difficile, meme apres la realisation d’une echoendoscopique et/ou de biopsies. La resection chirurgicale des tumeurs de plus de 2 cm est justifiee car elle permet une analyse histologique et un traitement carcinologique. Concernant les TSM gastriques de petite taille (

Abstract

Les progres de l’endoscopie interventionnelle oesophagienne permettent de proposer de plus en plus frequemment des techniques de traitement endoscopique pour des pathologies oesophagiennes, aussi bien dans le domaine des lesions superficielles neoplasiques ou preneoplasiques que des troubles moteurs ou des stenoses malignes ou benignes. L’hemorragie immediate ou retardee et la perforation restent les complications les plus frequemment observees au cours de ces procedures. Certaines techniques ont des complications plus specifiques qui doivent etre parfaitement connues avant la procedure. Les patients doivent etre informes de facon claire de ces risques. Ces risques doivent etre anticipes, et surtout l’endoscopiste doit connaitre leurs moyens de prise en charge. Plusieurs de ces complications peuvent etre actuellement maitrisees par des moyens medicaux et endoscopiques. Il faut neanmoins aussi connaitre les situations necessitant un recours a la chirurgie.

Abstract

La radiofrequence (RF) est un traitement valide de l’endobrachyoesophage dysplasique. Cette revue de la litterature a pour objectif d’evaluer les techniques, l’efficacite et les effets indesirables de la RF endoscopique dans d’autres indications, emergentes. Quatre etudes prospectives (total 69 patients) ont montre que la RF permettait d’obtenir une remission complete de neoplasies intraepitheliales oesophagiennes malpighiennes en dysplasie de haut grade ou avec carcinome epidermoide in situ dans 80 % des cas, avec cependant un risque substantiel de stenoses oesophagiennes proximales. Dans l’indication des ectasies vasculaires antrales de l’estomac, une etude pilote prospective (six patients), une etude prospective monocentrique ouverte (21 patients) et une etude retrospective multicentrique (24 patients) montrent que la RF semble un traitement efficace en termes de diminution du recours aux transfusions. Une etude prospective ouverte monocentrique (39 patients) et une etude retrospective multicentrique (17 patients) suggerent que la RF est un traitement efficace de la rectopathie radique hemorragique chronique. Une etude retrospective comparative (64 patients) montre que la radiofrequence ameliore la duree de permeabilite des protheses dans les situations de stenoses biliaires malignes. Une etude pilote suggere que la RF endobiliaire peut egalement etre une option interessante dans les stenoses biliaires benignes refractaires. Les donnees sont encore limitees concernant la radiofrequence lors de ponction sous echoendoscopie pour des cancers du pancreas localement avances non resequables et pour les traitements des adenopathies mediastinales. La radiofrequence endoscopique est une modalite therapeutique qui ouvre de nouvelles perspectives dans la destruction des neoplasies intraepitheliales oesophagiennes malpighiennes a un stade precoce, dans le traitement hemostatique de lesions vasculaires digestives (ectasies vasculaires antrales de l’estomac et rectopathie radique hemorragique) et dans les maladies biliaires.
