Plain English Summary

Background and study aims
Oesophagectomy is the surgical removal of the oesophagus (food pipe), for example to remove oesophageal cancer. Sometimes following oesophagectomy the lungs become inflamed - a condition that is called acute lung injury. This happens about 28% of the time following oesophagectomy and the causes for it are poorly understood. The condition can range in severity from causing mild breathlessness to more severe breathlessness that can require assistance from a ventilator (breathing machine) to help with breathing in intensive care. We believe that people who are severely vitamin D deficient may be more at risk of acute lung injury following the operation than those who are not. We have previously done research which suggests that people who need an oesophagectomy are usually vitamin D deficient with about half being very deficient. We have evidence from our previous studies that those with the lowest levels of vitamin D may be at increased risk of inflammation and acute lung injury. The aim of this study is to determine whether we can restore vitamin D levels rapidly in the week or so prior to surgery using a single dose of liquid vitamin D taken by mouth.

Who can participate?
Patients aged over 16 undergoing oesophagectomy for oesophageal cancer.

What does the study involve?
Participants are given one of three doses of liquid vitamin D about 7 days before their oesophagectomy. We then measure their blood vitamin D levels after 7, 10 and 14 days.

What are the possible benefits and risks of participating?

Oesophageal cancer/acute lung injury/oesophagecetomy


Patients will be given a single dose of oral Vigantol® liquid approximately 7 days preoperatively.

Doses will be 100,000 units, 200,000 units or 300,000 units of vitamin D.

Intervention type



Phase II

Drug names

Vitamin D (Vigantol®)

Primary outcome measure

The dose of Vigantol® that successfully increases serum vitamin D levels above 75 nmol/l in all cases

Secondary outcome measures

1. Safety and tolerability data - blood biochemistry, medication related side effects
2. Plasma 25D3 levels at 7, 10 and 14 days post dose
3. Plasma LL-37 (a downstream vitamin D target) at baseline and on the day of operation
4. Change in Plasma 1, 25 D3 (the biologically active hormone) from baseline on the day of operation
