01
The evidence
What an upper GI surgery expert witness is asked to determine
Upper GI claims commonly concern the interval between a leak occurring and its recognition. Tachycardia, pain out of proportion and rising inflammatory markers are the signs the records are examined for, and the argument usually rests on how those observations were interpreted.
- Whether the operation chosen was appropriate to the pathology and the patient assessed.
- Whether bariatric selection, counselling and follow-up met the expected standard.
- Whether an anastomotic leak was suspected and investigated when the observations changed.
- Whether reoperation or drainage took place within an appropriate period.
- Whether nutritional and metabolic follow-up after surgery was adequate.
Practitioners are listed across the United Kingdom and Republic of Ireland. Location can be narrowed in the register’s location listings before an instruction is made.

Questions answered
Frequently asked questions
Will an Upper GI Surgery expert witness respond to Part 35 questions?
Yes - CPR 35.6 entitles the parties to put written questions on a report, and answering them is part of the expert's duty to the court. A Upper GI Surgery report prepared for proceedings in England and Wales carries the Part 35 statement of truth, with equivalent duties applying in the other UK jurisdictions.
Can an Upper GI Surgery expert act as a single joint expert?
Where the court directs a single joint expert under CPR 35.7, the instruction is agreed between the parties and put jointly - a routine basis of instruction in this field. Whether a particular practitioner accepts SJE appointments is confirmed with the practitioner at the enquiry stage.
Will the expert attend joint discussions or give evidence at trial?
Where the court directs discussions between experts under CPR 35.12, they meet and produce a joint statement of what is agreed and what is disputed; attendance at trial - in person or by video link - is likewise a matter of court direction. These commitments are confirmed with the practitioner at instruction.
Can I choose an Upper GI Surgery expert of a specific gender, or one who assesses remotely?
Yes on both counts. Every listing displays the practitioner's gender, consulting locations and assessment types - face to face, remote or both - so sensitive-instruction preferences can be applied at the shortlisting stage, before any contact is made.
