Dysphagia and Reflux Case: Solid Food Only, Steadily Worse Over Four Months, Felt at the Lower Breastbone, With Twelve Years of Heartburn and a 4 kg Weight Loss in N.R.
The Case as Given
Four months after the gallbladder visit, N.R. returned with food sticking. N.R. described meat and bread "stopping behind the bottom of my breastbone" and having to drink water or stand up to get it down. Liquids pass without trouble. It started four months ago, maybe once a week, and now happens with most dinners. N.R. has lost 4 kg without trying. Heartburn for about twelve years, treated with over-the-counter antacids and, for the past two years, omeprazole 20 mg taken when needed rather than daily. Former smoker, 25 pack-years. Two or three beers on weekends.
Reading the Swallow in Stages
Swallowing has two broad stages that fail in different ways. Oropharyngeal dysphagia is trouble starting the swallow: coughing, choking or food going into the nose within a second of swallowing, often from a neurological or muscular cause. Esophageal dysphagia is a feeling of food sticking after the swallow has started, felt in the chest or at the lower neck. N.R. starts swallows without trouble and feels the food stop low in the chest several seconds later. This is esophageal dysphagia.
Solids, Liquids or Both
Trouble with solids only points to a mechanical narrowing: a ring, a stricture or a tumor, which a liquid can pass but a bolus cannot. Trouble with both solids and liquids from the start points to a problem with esophageal muscle or its nerve control, such as achalasia. N.R. has trouble with solids only.
The Shape of the Onset
A narrowing that comes and goes, with long spells of normal swallowing, fits a ring at the lower esophagus. A narrowing that worsens steadily over months, from occasional to nearly every meal, fits a growing lesion, either a peptic stricture from years of acid damage or a tumor. N.R.'s course is steady worsening over four months, with weight loss. That shape, in a 58-year-old former smoker with long-standing reflux, makes esophageal adenocarcinoma a possibility that must be excluded, along with a peptic stricture.
What Position and Timing Carry
N.R. stands up to help food pass, which suggests gravity is helping a bolus past a fixed narrowing. Food sticks with the evening meal, when N.R. eats most and fastest. There is no regurgitation of undigested food hours later, which argues against a large pouch or achalasia.
Reflux as a Description
The reflux guideline describes heartburn as a burning feeling behind the breastbone and regurgitation as the return of stomach contents into the mouth, and treats them as typical reflux symptoms (Katz et al., 2022). N.R. has heartburn most nights and regurgitation of sour fluid when bending. Reflux here is a description of symptoms, not yet a diagnosis of damage; whether acid has scarred or changed the esophageal lining can only be seen at endoscopy. Taking omeprazole only when needed means the lining may have been exposed to acid for years with little healing.
The Differential, Ranked
First: peptic stricture from long-standing reflux, the commonest cause of this pattern. Second: esophageal adenocarcinoma arising in Barrett's esophagus, less common but serious and supported by the steady course, weight loss and smoking. Third: a lower esophageal ring, less likely given the steady worsening. Fourth: eosinophilic esophagitis, which usually affects younger adults with food impactions and allergies; N.R. has neither. Achalasia is unlikely because liquids pass.
What Would Change the Ranking
Food that sticks higher, at the neck, would raise the chance of a ring or a web in the upper esophagus. Liquids becoming difficult would move achalasia up the list. A history of food allergies, asthma or repeated impactions since young adulthood would raise eosinophilic esophagitis. Blood in vomit or black stools would make an ulcer or a bleeding tumor more urgent. None of these is present today, and the ranking holds until endoscopy shows the lining.
How the Case Closes
Dysphagia with weight loss is an alarm feature at any age, and the dyspepsia guideline's age threshold does not apply to it (Moayyedi et al., 2017). The plan is an upper endoscopy within two weeks, with biopsies of any narrowing or abnormal lining, and dilation if a benign stricture is found. Omeprazole was changed to 20 mg daily before breakfast in the meantime, and N.R. was advised to cut food into small pieces, eat slowly and sit upright for meals. N.R. was told to come in the same day if food lodged and would not pass, or if drooling or inability to swallow saliva developed.

The Chamberlain PA 526 Week 4 instructions
In week four the case is difficulty swallowing alongside reflux. Start by placing the problem in the right stage of swallowing, oropharyngeal or esophageal, and say why. Separate trouble with solids from trouble with liquids early, since they point to different mechanisms. Describe the shape of the onset, intermittent or steadily worsening, and what that suggests. Note what position and timing add. Describe reflux in the guideline's terms, as symptoms, without assuming damage. Then rank the differential with reasons, including any serious diagnosis that must be excluded. Say what new findings would change the ranking. Close with a plan matched to the risk, including interim advice and instructions for a complete blockage. Cite the reflux and dyspepsia guidance you rely on.
Inside the PA 526 Week 4 example
The case gives N.R.'s account of meat and bread stopping behind the lower breastbone, liquids passing easily, weekly episodes growing to most dinners, a 4 kg loss, twelve years of heartburn and as-needed omeprazole, plus smoking history. A section places the complaint in the esophageal stage. Solids-only trouble is linked to a mechanical narrowing. The onset is described as steady, raising peptic stricture and adenocarcinoma. Standing to help food pass is read as gravity at a fixed narrowing. Reflux is described using the ACG terms for heartburn and regurgitation, citing Katz and colleagues. A ranked list places peptic stricture first and adenocarcinoma second, with a ring, eosinophilic esophagitis and achalasia lower. A section lists what would change the ranking, and the close cites the dyspepsia guideline and plans endoscopy.
PA 526 Week 4 rubric: what full points look like
Grading here follows the sequence of distinctions. Failing to place the complaint in the right stage of swallowing, or blending solids and liquids, loses the most because the differential depends on both. Faculty then look for the shape of the onset and what it implies, since a steadily worsening course changes urgency. Credit goes to describing reflux as symptoms rather than assuming esophagitis, and to a ranked differential with reasons rather than a list. Missing a serious diagnosis that must be excluded, such as cancer in an older smoker with weight loss, is a heavy deduction. A section on what would change the ranking earns marks. The plan is graded on whether its urgency matches the risk, and guidelines should be cited for alarm features and reflux.
Common PA 526 Week 4 mistakes, and how to avoid them
Many students lose marks on this case by treating dysphagia as one complaint and jumping to a reflux diagnosis. Send the case your section assigned, and the analysis drafted for you would place the problem in the correct swallowing stage, separate solids from liquids and describe the onset's shape before reaching a differential. Reflux is described in guideline terms, and the differential is ranked with reasons drawn from your case. A section lists the findings that would reorder it. The plan is matched to the risk in your patient, with interim advice. If your case points to the oropharyngeal stage instead, the analysis follows that route. Check each detail of history against your own case before adapting the reasoning.

PA 526 Week 4 questions, answered
My case describes heartburn only, with no swallowing trouble.
Then the paper is written on that, and the swallowing material becomes the contrast rather than the subject. The example still separates the described symptom from any label, and it uses the absence of swallowing difficulty as evidence in its own right, which is a move most drafts miss. Send the case as written and the emphasis follows it.
Does the paper need a diagnostic testing section?
Some sections require one and some stop at the reasoning. Where testing is wanted, the example ties each item to the specific question it would answer rather than listing what is available, and it says what result would change the argument. Where the assignment stops earlier, the example stops at the same place rather than showing a version your rubric does not reward.
How much of the history should be quoted back?
Less than most drafts use. The example quotes the two or three phrases that are doing the work and paraphrases the rest, which leaves room for analysis inside the word limit. A paper that reproduces the case in full before starting reads as padding, and markers on this module tend to say so directly in feedback.
