[Upper gastro-intestinal tumour stenosis treated by a new endoscopic approach]. / Sténose digestive tumorale haute traitée par une nouvelle approche endoscopique.

Gastric outlet obstruction (GOO) is a mechanical obstruction of the distal stomach or proximal duodenum. Surgical gastro-jejunostomy and self-expanding metal duodenal stents were the conventional treatments for GOO. In recent years, a new treatment option emerged using echo-guided endoscopic gastroenterostomy (EUS-GE). It appears to be a safe and effective technique with a clinical success rate of 85-90 % and a side effect rate of less than 18 %. Compared to metal duodenal prostheses, the risk of recurrence of GOO and of re-intervention is lower with EUS-GE. The rate of side effects also appears to be lower than with the surgical technique, with a shorter length of hospital stay. Randomised studies comparing these different techniques are still needed to determine a new treatment algorithm for GOO. We report a case of successful EUS-GE performed at our institution.

La «gastric outlet obstruction¼ (GOO) est une obstruction mécanique de l'estomac distal ou du duodénum proximal. La gastro-jéjunostomie chirurgicale et les endoprothèses métalliques auto-expansibles duodénales étaient les traitements conventionnels de la GOO. Ces dernières années, une nouvelle option thérapeutique est apparue utilisant la gastro-entéro-anastomose par voie endoscopique écho-guidée (GE-EEG). Elle semble être une technique sûre et efficace avec un taux de succès clinique de 85 à 90 % et un taux d'effets secondaires de moins de 18 %. Comparé aux prothèses duodénales métalliques, le risque de récidive de la GOO et de réintervention est plus faible avec la GE-EEG. Le taux de manifestations indésirables semble également être plus faible qu'avec la technique chirurgicale, avec une durée de séjour hospitalier plus courte. Des études randomisées comparant ces différentes techniques sont encore nécessaires pour déterminer un nouvel algorithme de traitement pour la GOO. Nous rapportons un cas de GE-EEG réalisée avec succès dans notre institution.

Alcohol intake increases the risk of HCC in hepatitis C virus-related compensated cirrhosis: A prospective study.

BACKGROUND & AIMS: Whether alcohol intake increases the risk of complications in patients with HCV-related cirrhosis remains unclear. The aim of this study was to determine the impact of alcohol intake and viral eradication on the risk of hepatocellular carcinoma (HCC), decompensation of cirrhosis and death. METHODS: Data on alcohol intake and viral eradication were prospectively collected in 192 patients with compensated HCV-related cirrhosis. RESULTS: 74 patients consumed alcohol (median alcohol intake: 15g/day); 68 reached viral eradication. During a median follow-up of 58months, 33 patients developed HCC, 53 experienced at least one decompensation event, and 39 died. The 5-year cumulative incidence rate of HCC was 10.6% (95% CI: 4.6-16.6) in abstainers vs. 23.8% (95% CI: 13.5-34.1) in consumers (p=0.087), and 2.0% (95% CI: 0-5.8) vs. 21.7% (95% CI: 14.2-29.2) in patients with and without viral eradication (p=0.002), respectively. The lowest risk of HCC was observed for patients without alcohol intake and with viral eradication (0%) followed by patients with alcohol intake and viral eradication (6.2% [95% CI: 0-18.4]), patients without alcohol intake and no viral eradication (15.9% [95% CI: 7.1-24.7]), and patients with alcohol intake and no viral eradication (29.2% [95% CI: 16.5-41.9]) (p=0.009). In multivariate analysis, lack of viral eradication and alcohol consumption were associated with the risk of HCC (hazard ratio for alcohol consumption: 3.43, 95% CI: 1.49-7.92, p=0.004). Alcohol intake did not influence the risk of decompensation or death. CONCLUSIONS: Light-to-moderate alcohol intake increases the risk of HCC in patients with HCV-related cirrhosis. Patient care should include measures to ensure abstinence. LAY SUMMARY: Whether alcohol intake increases the risk of complications in patients with HCV-related cirrhosis remains unclear. In this prospective study, light-to-moderate alcohol intake was associated with the risk of hepatocellular carcinoma in multivariate analysis. No patients who did not use alcohol and who reached viral eradication developed hepatocellular carcinoma during follow-up. The risk of hepatocellular carcinoma increased with alcohol intake or in patients without viral eradication and was highest when alcohol intake was present in the absence of viral eradication. Patients with HCV-related cirrhosis should be strongly advised against any alcohol intake. Patient care should include measures to ensure abstinence.

Crohn's Disease treated with azathioprine and basal cell carcinoma : three cases and literature review.

Three cases of basal cell carcinoma in Crohn's disease patients treated with azathioprine are described. A review of the literature is conducted concerning this association between the occurrence of basal cell carcinoma and the use of azathioprine. Recently, practical advice on screening and follow-up of these situations have been proposed but there are no validated dermatological recommendations.
