[Massive bleeding from the upper digestive tract in patients with pseudoaneurysm of splenic artery]. / Masywne krwawienie z górnego odcinka przewodu pokarmowego u chorego z tetniakiem rzekomym tetnicy sledzionowej--opis przypadku.

Pancreatic pseudocysts are common complication of both chronic and acute pancreatitis. Sanguination from damaged peripancreatic vessels into the lumen of pseudocyst results in pseudoaneurysm. The rupture of pancreatic pseudoaneurysm into the lumen of digestive tract causes massive bleeding witch source is often difficult to find during endoscopic examination. We present a case of patient with chronic alcohol pancreatitis, with pancreatic pseudocyst and of acute bleeding from upper digestive tract. In the endoscopy we found gastric ulcer with visible vessel. During hospitalization we observed increase the diameter of pseudocyst and circulation of it's liquid contence. Second-look endoscopy showed gastric fundic varices. Surgical operation revealed pseudoaneurysm of splenic artery inserting pressure on gastric wall.

[Endoscopic treatment of gastroesophageal reflux disease--new possibilities]. / Leczenie endoskopowe choroby refluksowej przelyku--nowe mozliwosci.

Gastro-esophageal reflux disease (GERD) is one of the most important problems of gastroenterology at present. The symptoms of GERD have negative influence of patients' life on a daily basis. The principal aim of reflux disease treatment is to eliminate or alleviate the symptoms, to heal tissue damages and to reduce the frequency and duration of recurrences. Lifestyle and dietary modification are of only limited value in GERD treatment. Proton pump inhibitors (PPI) are the mainstay of GERD pharmacotherapy for both initial episode and long-term management. Surgical treatment is indicated in: complicated GERD, in patients who need high effective dose of medication, young patients who need lifelong PPI, patients with big hiatus hernia. Laparoscopic Nissen fundoplication has become the operation of choice. Nevertheless patients who have undergone fundoplication may experience adverse post operative complication. The useful alternatives in the management of GERD may indeed eventually prove the new endoscopic methods of minimally invasive treatment which are currently under thorough evaluation. The most promising methods of endoscopic treatment of GERD have been discussed: radiofrequency ablation (the Streett's procedure), endoscopic gastroplasty, endoscopic implantation of biopolymer hydrogel prosthesis.

The impact of Helicobacter pylori on EGF, EGF receptor, and the c-erb-B2 expression.

PURPOSE: Increased expression of epidermal growth factor (EGF), its receptor (EGFR), and c-erb-B2 protein, which is homological with the EGF receptor, in gastric mucosa, may play a role in gastric carcinogenesis. We assessed if the infection and eradication of Helicobacter pylori (H. pylori) affects the gastric expression of growth factors and serum gastrin concentrations. PATIENTS/METHODS: We examined immunohistochemically gastric EGF and both receptors' expression in: gastric cancer (GC; n=29), chronic gastritis with H. pylori infection (GHp+; n=40) before and after eradication and in patients without H. pylori infection (GHp-; n=42). RESULTS: Before the eradication therapy, gastric mucosal EGF and both receptor's expressions in GHp+ patients were increased compared to GHp- (p<0.05), but were similar to GC. After eradication, EGF and the receptor's expression significantly decreased in the gastric body. Both EGFR and c-erb-B2 expression in the antrum were still higher than in GHp- (p<0.05), and remained comparable to GC. CONCLUSIONS: In patients with H. pylori infection the gastric mucosal EGF, EGFR, and c-erb-B2 expressions are similar to those observed in gastric cancer. The persistence of the antral expression of receptors after eradication, at a level comparable to the gastric cancer group, suggests their eventual role in the progression of changes initiated by H. pylori toward carcinogenesis.
