Molecular detection of Helicobacter pylori in oral samples from patients suffering digestive pathologies
2010
Objective: to determine the simultaneous presence of H. pylori in both the oral cavity and gastric mucosal in patients suffering digestive pathologies and to establish the possible association between the presence of H. pylori in the oral cavity and the gingivoperiodontal pathology. Study design: Patients with gastric symptoms (case group) and asymptomatic patients (control group) seen at the Gastroenterology Department of Dr. Julio C. Perrando Hospital (Resistencia, Argentina) were selected. Dental plaque and saliva samples from both groups were obtained. In the case group, gastric biopsy samples were also taken. H. pylori was detected in gastric biopsies by histological stains, and Polyme…
Robotic Versus Laparoscopic Gastric Resection for Primary Gastrointestinal Stromal Tumors5 cm: A Size-Matched and Location-Matched Comparison.
2017
This study compared robotic (RR) and laparoscopic resection (LR) for primary gastrointestinal stromal tumors (GISTs) of the stomach >5 cm. Twelve consecutive patients who underwent RR from 2012 to 2015 were matched for tumor size and location with 24 patients who underwent LR from 2000 to 2012. The median tumor size was 7.1 cm (range, 5.5 to 11.5). GISTs were resected by wedge resection (91.7%) or distal gastrectomy. The median RR operative time was longer than that of LR (162.5 vs. 130 min, respectively; P=0.004). Only 1 LR patient required conversion. The time to flatus and hospital stay were similar between groups. Overall, 3 patients developed minor postoperative complications that w…
Predictors of Re‐bleeding and Mortality Among Patients with Refractory Variceal Bleeding Undergoing Salvage Transjugular Intrahepatic Portosystemic S…
2018
Abstract Background Transjugular intrahepatic portosystemic shunt (TIPS) has proven clinical efcacy as rescue therapy for cirrhotic patients with acute portal hypertensive bleeding who fail endoscopic treatment. Aims To investigate predictive factors of 6-week and 1-year mortality in patients undergoing salvage TIPS for refractory portal hypertensive bleeding. Methods A total of 144 consecutive patients were retrospectively evaluated. Three logistic regression multivariate models were estimated to individualize prognostic factors for 6-week and 12-month mortality. Log-rank test was used to evaluate survival according to Child–Pugh classes and Bureau’s criteria. Results Mean age 51±10 years,…
Whipple's pancreaticoduodenectomy: Surgical technique and perioperative clinical outcomes in a single center
2015
Abstract Introduction Pancreatic cancer is the fourth cause of death from cancer in Western countries. The radical surgical resection is the only curative option for this pathology. The prevalence of this disease increases with age in population. The causes of pancreatic cancer are unknown, but we consider risk factors like smoke and tobacco usage, alcohol consumption coffee, history of diabetes or chronic pancreatitis. In this study we report our experience in the treatment of resectable pancreatic cancer and periampullary neoplasms with particular attention to evaluate the evolution of surgical technique and the clinical postoperative outcomes. Methods In our Department between January 20…
Influence of identification and preservation of pelvic autonomic nerves in rectal cancer surgery on bladder dysfunction after total mesorectal excisi…
2003
PURPOSE: Given the improvement in oncologic outcome after the introduction of total mesorectal excision for the treatment of rectal cancer, the objective of the present study was to determine the frequency of identification and preservation of the pelvic autonomic nerves and to identify a possible link between postoperative micturition disturbances and the extent of the radical resection. METHODS: Between March 1997 and December 2001, 150 patients with adenocarcinoma of the rectum (≤16 cm from the anal verge) underwent surgery, with sphincter preservation in 112 cases (74.7 percent). Sixty-three patients (42 percent) were classified as American Society of Anesthesiologists Stage III and two…
Effect of intravenous application of esomeprazole 40???mg versus pantoprazole 40???mg on 24-hour intragastric pH in healthy adults
2007
BACKGROUND: It has been demonstrated that therapy with proton pump inhibitors reduces recurrence of bleeding following initial endoscopic treatment of bleeding peptic ulcers. AIM: This study compared the effects of esomeprazole 40 mg and pantoprazole 40 mg on intragastric acid control. Both substances were administered intravenously as 15-min infusion and as bolus injection. METHODS: Healthy men and women volunteers were enrolled in this single-center, open, randomized, three-way crossover study. After administration of esomeprazole 40 mg and pantoprazole 40 mg intravenously as 15-min infusion, and pantoprazole 40 mg intravenously as bolus injection, continuous 24-h intragastric pH monitori…
The effects of omeprazole 20 and 40 mg twice daily on intragastric acidity in duodenal ulcer patients.
1996
BACKGROUND: The combination of omeprazole with amoxycillin or clarithromycin is used as treatment against Helicobacter pylori. It seems likely that the antibacterial activity of the antibiotic may be improved by increasing gastric pH towards neutrality, and a twice daily regimen of omeprazole is probably needed. AIM: To assess the effects of twice daily administration of omeprazole 20 and 40 mg. METHODS: Twelve duodenal ulcer patients in remission were randomized to receive in single-blind fashion either placebo, omeprazole 20 mg or omeprazole 40 mg twice daily (08.00 and 20.00 h). On the sixth day of dosing they underwent 24-h gastric pH-metry. RESULTS: Omeprazole 20 and 40 mg b.d. produce…
Surgical treatment of gastric cancer in Latvia: Results of centralized experience
2009
Although the mortality for gastric cancer is decreasing in Western Europe and United States, it still remains high in Eastern Europe. This study was aimed at evaluating short- and long-term results of surgical treatment of gastric cancer performed in Latvia Oncology Center.Retrospectively collected data from 461 patients who underwent gastrectomy with curative intent in Latvia Oncology Center from January 2001 to December 2005 were analyzed statistically.An average (range) of 92.2 (81-102) R0-R1 gastrectomies was performed each year. Post-operative complications occurred in 75 patients (16.3%); in-hospital mortality was 3.3%. The overall 5-year survival was 50.8%. In 444 cases (96.3%) there…
Invisible gastric carcinoma detected by random biopsy: long-term results after photodynamic therapy
2008
Background and study aims Gastric cancer diagnosed from routine gastric biopsies without any evidence of a visible lesion and negative repeated biopsies is an infrequent but serious clinical problem for which gastrectomy has usually been recommended, even if operative specimens do not show cancer either. We report on a series of 22 such patients undergoing long-term follow-up after attempted treatment with photodynamic therapy (PDT). Patients and methods 22 patients with invisible gastric cancer (IGC) who presented during a 10-year period (10 men, mean age 56 +/- 15 years) were prospectively included. Initial histopathological findings confirmed by second opinion included 10 well-differenti…
Absence of tolerance in duodenal ulcer patients treated for 28 days with a bedtime dose of roxatidine or ranitidine
1996
There is much experimental work on the occurrence of tolerance to the antisecretory effect of H2-receptor antagonists in healthy subjects, while data on its development in patients with duodenal ulcer are poor and conflicting. Moreover, this phenomenon has not been studied previously with 24 h gastric pH-metry in patients with active duodenal ulcer. For these reasons, we carried out a prospective pharmacodynamic investigation in 48 patients with endoscopically proven duodenal ulcer using the well-established once daily dosing schedule of H2 blockers. They were studied by means of 24 h continuous endoluminal pH-metry which was performed before, on d1 and d28 after receiving an oral bedtime d…
