ABSTRACT
Performing endoscopic retrograde cholangiopancreatography (ERCP) in bariatric patients with gastric bypass is often challenging. Many techniques have been described. Recently, Endoscopic ultrasound (EUS) - direct transgastric ERCP (EDGE) by using lumen-apposing metal stent (LAMS) has shown efficacy to reach biliary orifice and perform conventional ERCP with good safety profile and low risk of adverse events.
La réalisation d'une cholangiographie rétrograde (CPRE) chez les patients avec un bypass gastrique a longtemps posé des difficultés. Durant les dernières années, quelques techniques ont été développées pour permettre l'extraction de lithiases cholédociennes chez ces patients. Récemment, une nouvelle technique consistant à créer une fistule gastro-gastrique avec la mise en place d'un stent permettant le passage du duodénoscope a montré un excellent taux de réussite, avec un bon profil de sécurité et un faible taux de complications.

Lynch syndrome is a hereditary predisposition to several cancers. The goals of our study were to know the different mutations in our Lynch population, to evaluate the prevalence of cancers in this population and to determine the mean age of onset of those cancers. This retrospective study includes proven carriers of a MMR mutation diagnosed either by the CHU of Liège or either by the CHC Saint-Joseph in Liège, Belgium. We noted a clear majority of MSH2 mutations (50 %) in the Lynch families recorded in Liège, which is different from the main literature. In our study population (106 subjects), 65 % of subjects were affected by at least one cancer. Prevalences for colorectal and endometrial cancers are, respectively, 50 % and 27.5 %. We found no difference in the mean age of onset of cancers compared to literature. We discuss the follow-up of Lynch patients and the interest of additional exams such as hysteroscopy and cystoscopy.
Le syndrome de Lynch est un syndrome de prédisposition héréditaire à un certain nombre de cancers. Les objectifs de notre étude sont de connaître la répartition des différentes mutations dans la population Lynch prise en charge dans nos centres, d'évaluer la prévalence des cancers présentés par les patients Lynch de cette population et de déterminer l'âge moyen d'apparition de ces cancers. Cette étude rétrospective inclut les porteurs confirmés d'une mutation MMR ayant été diagnostiqués, soit par le CHU de Liège, soit par le CHC Saint-Joseph à Liège. Nous avons constaté une nette majorité de mutations MSH2 (50 %) parmi les familles Lynch répertoriées à Liège, ce qui est différent de ce qui est décrit dans la littérature. Dans notre population d'étude (106 sujets), 65 % des sujets ont présenté au moins un cancer. Les prévalences du cancer colorectal et de l'endomètre sont, respectivement, de 50 % et 27.5 %. Nous n'avons pas trouvé de différence dans les âges moyens de présentation des cancers par rapport à la littérature existante. Nous discutons du suivi des patients porteurs d'un syndrome de Lynch et de la place d'examens supplémentaires comme l'hystéroscopie et la cystoscopie.

Colorectal cancer (CRC) is a leading cause of cancer related death in the western countries. It remains an important health problem, often under-diagnosed. The symptoms can appear very late and about 25% of the patients are diagnosed at metastatic stage. Familial adenomatous polyposis (FAP) is an inherited colorectal cancer syndrome, characterized by the early onset of hundred to thousands of adenomatous polyps in the colon and rectum. Left untreated, there is a nearly 100% cumulative risk of progression to CRC by the age of 35-40 years, as well as an increased risk of various other malignancies. CRC can be prevented by the identification of the high risk population and by the timely implementation of rigid screening programs which will lead to special medico-surgical interventions.

The authors review the actual position of medical treatment for human gastric cancer. Chemotherapy has been evaluated first in palliative situation, then as adjuvant post-surgical approach either through systemic or intraperitoneal route. Now chemotherapy may also be proposed as neoadjuvant (before surgery) treatment as part of an integrated global pluridisciplinary approach. New hopes to improve the prognosis come then from both neoadjuvant and adjuvant chemotherapy (+/- radiotherapy) and further from less toxic infusional therapies (chronomodulation), new schedules with proved active molecules (docetaxel, oxaliplatin, irinotecan, pemetrexed) as well as from new targeted treatments (against ie, EGF-receptor and angiogenesis).

A 66-year-old man, Ag HBs negative, suffering from glomerulonephritis was treated with prednisone. Hepatitis B reactivation was observed after increasing and regression of corticotherapy. Pathogenesis, efficient therapy and prevention of reactivation of hepatitis B will be reviewed.

Barrett's oesophagus (BE) is a segment of columnar lined epithelium in the distal oesophagus, above the gastrooesophageal junction. So it is important to localize this junction endoscopically; the proximal margin of the gastric folds is the anatomic landmark. Another important feature of BE is the specialized intestinal metaplasia. In the aetiology of this condition, acid reflux is a primary event but there is evidence that other factors are causal. As BE is a well known premalignant condition, detection of dysplastic epithelium and its severity is the crucial element. Practical guidelines are presented for endoscopic surveillance program. The purpose is the early detection of high grade dysplasia and carcinoma to advise oesophagectomy or endoscopic ablation therapy for patients unfit to undergo surgery.

In our institution, MRCP is actually replacing diagnostic ERCP. This study is addressing its accuracy in the diagnosis of symptomatic choledocholithiasis. 137 MRCP were performed in patients with upper abdominal pain and biological anomalies (n = 48), pain with cholelithiasis at sonography (n = 69) or non-alcoholic acute pancreatitis (n = 20) on a 1.5 T system with high gradients using a standardized combination of breath-hold HASTE and RARE sequences. We included in our study 74 patients who underwent as second test ERCP (n = 36), peroperative cholangiography (n = 13), or extensive follow-up with laboratory tests and/or sonography (n = 25). All examinations were judged as diagnostic, discrepancies between direct cholangiography and MRCP being noted in 4 patients (5.4%). Lithiasis was misinterpreted on MRCP as bubbles in 2 patients after sphincterotomy or surgery. We had two false positive diagnoses on MRCP: in one patient peroperative cholangiography was negative and in the other one ERCP was negative. With a sensitivity and PPV of 92%, a specificity and NPV of 96% MRCP in our experience is shown as an accurate diagnostic tool for the detection of stone in the common bile duct replacing ERCP.

The incidence of pancreatic cancer (PC) is increasing in developing countries. Smoking, reduced consumption of fruits and vegetables, chronic pancreatitis appear to be the best established risk factors. PC is often diagnosed at a late stage. We have to look for it when dyspepsia with weight loss, pancreatic pain or impaired glucose tolerance occurs. Tumor markers are briefly exposed and we discuss the place of endoscopic retrograde cholangiopancreatography (ERCP) after non invasive imaging techniques.
