Peptic ulcers

Alexandra K Eicher, H Matthew Berns, James M Wells
Gastric diseases, including peptic ulcer disease and gastric cancer, are highly prevalent in human beings. Despite this, the cellular biology of the stomach remains poorly understood relative to other gastrointestinal organs such as the liver, intestine, and colon. In particular, little is known about the molecular basis of stomach development and the differentiation of gastric lineages. Although animal models are useful for studying gastric development, function, and disease, there are major structural and physiological differences in human stomachs that render these models insufficient...

The mucosal response to injury can best be understood as a complex layering of different responses that may be invoked depending upon the size and nature of the injury, the persistence of the injurious stimulus, and the availability of various trophic host factors that stimulate repair. There is a hierarchy of responses that ranges from small rapid resealing of acute apical membrane or single cell wounds through the long term attempt to heal a giant peptic ulcer or respond to inflammatory bowel disease. Although much previous attention has been paid to the local factors that regulate these pathways and responses, there is increasing interest in systemic factors that may act either by the production of cytokines and trophic factors or by the direct migration of bone marrow derived stem cells into the mucosal wound...

BACKGROUND: Helicobacter pylori (H pylori) infection has been implicated in a number of malignancies and non-malignant conditions including peptic ulcers, non-ulcer dyspepsia, recurrent peptic ulcer bleeding, unexplained iron deficiency anaemia, idiopathic thrombocytopaenia purpura, and colorectal adenomas. The confirmatory diagnosis of H pylori is by endoscopic biopsy, followed by histopathological examination using haemotoxylin and eosin (H & E) stain or special stains such as Giemsa stain and Warthin-Starry stain...

Backgrounds/Aims: Postcholecystectomy syndrome represents a heterogeneous group of symptoms and findings in patients who have previously undergone cholecystectomy. It is rare and under-reported in Saudi Arabia. It can be attributed to many complications such as bile duct injury, biliary leak, retained common bile duct stones, recurrent bile duct stones, and bile duct strictures. In this study, we aimed to analyze the causes and evaluate the approach to postcholecystectomy syndrome in our local Saudi Arabian community because of the vast number of cases encountered in our hospital for gallbladder clinical conditions and its related complications...

Proton pump inhibitors (PPIs) have been widely used in the treatment of gastroesophageal reflux disease and peptic ulcer disease. Although they have a potent acid suppressive effect and excellent efficacy in acid-related diseases, PPI-induced rhabdomyolysis has been reported. Here, we report the case of a patient with reflux esophagitis who developed rhabdomyolysis after esomeprazole treatment. A 67-year-old man with reflux esophagitis who had started esomeprazole treatment for the preceding 10 months complained of back and limb fatigue and myalgia...

Non-variceal upper gastrointestinal bleeding continues to be an important cause of morbidity and mortality. The most common causes include peptic ulcer disease, Mallory-Weiss syndrome, erosive gastritis, duodenitis, esophagitis, malignancy, angiodysplasias and Dieulafoy's lesion. Initial assessment and early aggressive resuscitation significantly improves outcomes. Upper gastrointestinal endoscopy continues to be the gold standard for diagnosis and treatment. We present a comprehensive review of literature for the evaluation and management of non-variceal upper gastrointestinal bleeding...

AIMS: Most gastric carcinomas develop in association with mucosal atrophy and hypochlorhydria, whereas benign peptic ulcers are acid-related. Given that acid sterilizes gastric contents, we hypothesized that ulcerated gastric cancers may be associated with increased luminal microbes compared with peptic ulcers, and that this feature may represent a helpful diagnostic clue to the presence of malignancy. We performed this study to determine whether features of luminal debris, including microorganisms, from ulcerated gastric cancers were significantly different from those of debris associated with benign ulcers...

BACKGROUND: With the worldwide epidemic of obesity, an increasing number of bariatric operations and antireflux fundoplications are being performed. Despite low morbidity of the primary foregut surgery, completion gastrectomy may be necessary as a definitive procedure for complications of prior foregut surgery; however, the literature evaluating outcomes after completion gastrectomy with esophagojejunostomy (EJ) for benign diseases is limited. We present our experience of completion gastrectomy with Roux-en-Y EJ in the setting of benign disease at a single tertiary center...

BACKGROUND: Upper gastrointestinal disorders are common in clinical practice, for example, gastritis, peptic ulcer disease, and gastroesophageal reflux disease. Panendoscopy or upper gastrointestinal endoscopy is viewed as the primary tool for examining the upper gastrointestinal mucosa, and permitting biopsy and endoscopic therapy. Although panendoscopy is considered to be a safe procedure with minimal complications, there are still some adverse effects, and patients are often anxious about undergoing invasive procedures...

BACKGROUND: Consensus on the necessity of esophagogastroduodenoscopy (EGD) before bariatric surgery is lacking. Recommendations and practices vary by country and unit. Several reports have expressed concerns on gastroesophageal reflux disease (GERD) and its consequences after sleeve gastrectomy (SG) and the risk of leaving a premalignant lesion in the excluded stomach after Roux-en-Y gastric bypass (RYGB). OBJECTIVES: We explored the number and types of clinically significant findings in preoperative EGDs and how they associate with preexisting GERD-symptoms (SG) and premalignant lesions (RYGB)...
