Mr. Jones HPI Mr. Jones is a 45 year old male who presents to your clinic with epigastric abdominal pain x 2 weeks. He describes it as a burning pain which is non-radiating and is worse after he eats. He has frequent belching with bloating sensation but denies nausea, vomiting, diarrhea, constipation, or weight loss. He has tried rolaids which do help a little. Which symptoms support the possible diagnosis of PUD?

Principles in Selecting H. pylori Test Based on the following: • Probability of previously eradicated infection • Probability of current active infection • Need to document active infection • Need for rapid result • Patient preferences • Cost (both of test and possible unnecessary treatment)

Mr. Jones Prior Ulcer History On further questioning Mr. Jones states he had similar abdominal pain three years ago and was told by his physician at that time that it was most likely due to an ulcer. He took “the purple pill” for a month and his symptoms resolved. He had no definitive diagnostic tests done at that time. What would you do at this time?

Final Recommendations Alarm symptoms = endoscopy. No alarm symptoms = medical management favored approach Studies still in progress to evaluate if medical management versus vs endoscopy is both medically and cost effective in long-term Lack of response or the recurrence of symptoms warrants endoscopy
