Tarrant v Monkhouse
[2025] EWHC 2576 (KB)·2025·Liability decided at trial
After a sleeve gastrectomy the claimant had trouble swallowing; the surgeon performed a gastroscopy and balloon dilatation, after which the sleeve leaked. The judge found no breach of duty in the post-operative care or the dilatation and dismissed the claim despite the very serious consequences.
A bad outcome after a recognised complication is not enough; the claimant must show the treatment decision fell outside what a responsible body of surgeons would do. Sympathy for the patient does not change the legal test.
