Problem 11 Reflux in a 35-year-old man

The patient is given some counselling on lifestyle measures and encouraged to use over-the-counter medications as required. He returns for a follow-up visit 3 months later. He has stopped smoking and has reduced his alcohol intake. He has also managed to lose 5 kg in weight. He feels healthier than ever before but many of his dyspeptic symptoms persist.

You adopt a ‘test and treat’ management strategy. You refer the patient for a breath test which comes back positive. You prescribe a 10 day course of triple therapy (esomeprazole, amoxicillin and metronidazole) and arrange to see him back for review in 6 weeks. At his review you find that after an initial improvement his symptoms have recurred in the preceding week.

A repeat breath test is positive and the patient is given a further course of triple therapy which gives him good symptomatic relief. Two years later the patient returns. His dyspepsia-type symptoms have settled, but his main complaint now is heartburn. Also, when he bends over he can reflux gastric content into his mouth, making him cough. Six months previously he was started on pantoprazole but every time he stops the medication his symptoms worsen. He does not like the idea of taking tablets long term and wishes to discuss other treatment options. He has heard about endoscopic methods for ‘fixing the valve’.

The patient has already tried increasing the dosage of his PPI, but to no effect.

Your patient decides not to opt for surgery and he continues on his PPI therapy. A few years later he returns. Despite deciding to continue on medical therapy his compliance with acid suppression has been poor. For the past few months his reflux symptoms have worsened and he had been feeling increasingly tired. You think he looks pale and you perform some blood tests.

His haemoglobin is 102 g/L, white cell count 6.7 × 109/L, platelet count 275 × 109/L and mean cell volume 72 fL.

You are concerned by his anaemia and arrange for him to undergo an urgent upper GI endoscopy. (Remember, in iron deficient anaemia, if the upper GI endoscopy is normal, a colonoscopy may be indicated.) The view in Figure 11.1 shows the lower oesophagus.

Biopsies are reported as showing Barrett’s metaplasia with features of high-grade dysplasia. There are no features of malignancy on the samples analysed. You commence the patient on high-dose PPI and reinforce the importance of compliance. Another endoscopy is arranged for 6 weeks’ time with repeat biopsies.

Despite good compliance with drug therapy, the repeat endoscopy identifies a small area of raised Barrett’s mucosa which is biopsied, along with multiple other sites. These repeat biopsies now show low-grade dysplasia, except for the biopsies from the raised area, which identify localized high-grade dysplasia with features of carcinoma in situ.

Endoscopic ultrasound confirms a small nodular area which is staged as T1 disease at most. No other mucosal abnormality is identified and the surrounding lymph nodes are not suspicious of metastatic disease. The staging CT scan is reported as normal.

Your patient is treated by endoscopic mucosal resection (EMR) and the abnormal area is completely excised. He will need to continue on lifelong PPI therapy and he will need regular endoscopic surveillance to monitor his Barrett’s segment.
