About option 'd'
Increased risk of esophageal cancer —
Patients with achalasia are generally thought to be at increased risk of developing esophageal cancer, which is typically squamous cell type, although studies have also shown an increased risk of esophageal adenocarcinoma. (but some studies have shown no increased risk.)
The risk is not high enough to advice routine endoscopy in achalasia patients. A guideline issued by the American Society of Gastrointestinal Endoscopy suggests that there are insufficient data to support routine endoscopic surveillance for patients with achalasia. If surveillance were to be considered, it would be reasonable to initiate it 15 years after the onset of symptoms
