Hydrogen sulfide (H₂S) is an endogenous mediator, synthesized from l-cysteine by cystathionine γ-lyase (CSE), cystathionine β-synthase (CBS) or 3-mercaptopyruvate sulfurtransferase (3-MST). The mechanism(s) involved in H₂S-gastroprotection against ischemia/reperfusion (I/R) lesions and their time-dependent progression into deeper gastric ulcerations have been little studied. We determined the effect of l-cysteine, H₂S-releasing NaHS or slow H₂S releasing compound GYY4137 on gastric blood flow (GBF) and gastric lesions induced by 30 min of I followed by 3, 6, 24 and 48 h of R...

Primary gastrointestinal (GI) lymphoma is a heterogeneous disease with varied clinical presentations. The stomach is the most common GI site and accounts for 70% to 75% of GI lymphomas. We present a patient with gastric diffuse large B cell lymphoma (DLBCL) who presented with significant weight loss, early satiety, and multifocal ulcerated gastric lesions. Esophagoduodenoscopy should be performed in patients presenting with warning symptoms as in our case. Diagnosis is usually made by endoscopic biopsies. Multiple treatment modalities including surgery, radiotherapy, and chemotherapy have been used...

Granulomas are rarely seen in gastric biopsies mostly as an involvement of granulomatous diseases like sarcoidosis, Crohn's disease, infections, neoplasms, and vasculitis. Here, we claim cyanoacrylate as a foreign body type granuloma-causing agent in the stomach after vascular embolisation. We present cyanoacrylate associated gastric changes of three cases: two endoscopic biopsies and one gastric resection. In two cases, cyanoacrylate associated ulcers and granulomatous inflammation were observed in gastric mucosal biopsies following endoscopic examination after 7 months and 6 years of the glue injections, respectively...

REVIEW
P V Valli, C Gubler
The worldwide number of performed bariatric surgeries is increasing continuously, whereas laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy are conducted most frequently. Alongside with the usual post-operative and metabolic complications, luminal complications such as anastomotic bleeding, ulceration, leakage, fistula formation, enlargement and stenosis of the anastomosis may occur. Evolution of interventional endoscopy frequently allows endoscopic management of complications, avoiding surgical interventions in most cases...

Background The German S3 guideline "H. pylori and gastroduodenal ulcer disease" clearly recommends how to diagnose H. pylori infection. It also states when and how eradication therapy should be done. However, there are only few data available on the management of these patients in daily routine. With this survey, we wanted to gather information on how primary care physicians are involved in the management of H. pylori infection and how they follow the guideline recommendations. From this, consequences for the update of the new S2k guideline 2016 and their communication should be derived...

Corticosteroids are used to treat variety of diseases like bronchial asthma. However, long term corticosteroids have a gastric ulcerogenic potential. Montelukast (MTK) and nigella sativa oil (NSO) are used in treatment of bronchial asthma. Previous studies showed that MTK and NSO had gastroprotective effects in other models of gastric ulcer. The present study assesses synergistic gastroprotective effects of both drugs in dexamethasone (DXM)-induced gastric damage. 50 male rats were divided into 5 groups; normal control (I), DXM group (II), MTK+DXM group (III), NSO+DXM group (IV), MTK+NSO+DXM group (V)...
