ABSTRACT
Duodenal varices are detected infrequently, and their rupture is very rare. We encountered an 87-year-old man who developed duodenal varices rupture during chemotherapy with atezolizumab and bevacizumab (ATZ/BV) for hepatocellular carcinoma. We identified massive bleeding of a ruptured varix in the horizontal portion of the duodenum with emergency esophagogastroduodenoscopy (EGD). Successful hemostasis was achieved by endoscopic injection sclerotherapy with Histoacryl. Although ATZ/BV can cause esophageal varices rupture, there have been no cases of duodenal varices rupture. We should take care to check the duodenal varices as well as esophagogastric varices before ATZ/BV treatment.

BACKGROUND: Supragastric belching (SGB) may play a role in the pathophysiology of proton pump inhibitors (PPIs)-refractoriness in gastroesophageal reflux disease (GERD). SGB may be present in up to 40% of reflux symptoms in PPI-refractory GERD. Most reports on SGB have come from Western countries, and little is known about the prevalence and relevance of SGB in Asian refractory GERD patients. This study aimed at comparing the role of SGB in GERD patients in Japan and the UK. METHODS: We re-analyzed impedance-pH monitoring tracings from patients who were referred to tertiary centers in Japan and the UK due to PPI-refractory reflux symptoms. The prevalence of excessive SGB and the impact of SGB on reflux symptoms were compared between the two countries. RESULTS: Impedance-pH tracings from124 Japanese and 83 British patients were re-analyzed. Japanese patients were significantly younger and had smaller body mass index than the British (P < 0.001). Japanese patients had significantly lower prevalence of excessive SGB (18.5%) than the UK (36.1%) irrespective of reflux phenotype (P = 0.006). Logistic regression analysis showed that the geographical/cultural difference was the only factor associated with the different prevalence of SGB (odds ratio; 2.91, 95% CI 1.09-7.73, P = 0.032). SGB were related to typical reflux symptoms very rarely in Japan [0% (0-4.9)] compared to the UK [35% (0-54.1)] (P = 0.071). CONCLUSIONS: The prevalence of SGB and their impact on reflux symptoms is significantly lower in Japan compared to the UK. The difference is not related to reflux parameters but might come from ethnic/cultural factors to be further characterized.
