Upper GI for FRCS (Gen Surg)

Oesophago-gastric surgery spans benign disease, cancer and obesity. The domain covers reflux and hiatus hernia, achalasia and the motility disorders, oesophageal perforation, strictures and foreign bodies; Barrett’s oesophagus and early neoplasia, the staging and treatment of oesophageal, junctional and gastric cancer, GIST, lymphoma and gastroduodenal polyps; peptic ulcer disease and its complications, and reconstruction after gastrectomy; and obesity and metabolic surgery — selection, the operations, and their early and late complications, including the bariatric patient who presents to a general surgeon on call.

What the paper tends to test

  • Cancer questions ask for the next staging investigation, the operation for a given site and stage, or the role of neoadjuvant treatment.
  • Barrett’s questions test surveillance and the endoscopic treatment of dysplasia and early cancer.
  • Perforation questions turn on the cause, the delay and the patient’s physiology.
  • Bariatric questions test the complications that present as emergencies — internal hernia, leak, marginal ulcer — and the nutritional sequelae.
  • Reconstruction questions ask which anastomosis gives the best function after a given resection.

Classic traps and discriminators

  • Colicky pain after a Roux-en-Y gastric bypass is an internal hernia until proven otherwise, even with a normal CT.
  • A submucosal lesion with normal overlying mucosa needs endoscopic ultrasound, not repeated biopsy.
  • Neoadjuvant treatment for oesophago-gastric adenocarcinoma has changed in recent years; learn the current UK approach, not an older textbook’s.

medium

A 41-year-old man has had heartburn and regurgitation for six years. Symptoms are only partly controlled on twice-daily omeprazole and he asks about antireflux surgery. Endoscopy on treatment shows a 2 cm sliding hiatus hernia and normal mucosa. High-resolution manometry is arranged.

Which additional investigation is most important before offering fundoplication?

How sure are you?
medium

A 61-year-old man has a gastroscopy for reflux symptoms. There is a C4M6 segment of columnar-lined oesophagus above a 3 cm hiatus hernia, with no visible lesion. Quadrantic biopsies show intestinal metaplasia with no dysplasia. He is fit and wishes to have surveillance.

At what interval should his next surveillance endoscopy be planned?

Upper GI questions, answered

Is bariatric surgery in the FRCS (Gen Surg) syllabus?

Yes. Morbid obesity is in the oesophago-gastric section of the syllabus, and every general surgeon on call will see the complications of bariatric surgery.
