Anti-Reflux Surgery (Magnetic Sphincter Augmentation)
Definition- Non-anatomical altering, life style anti-reflux surgery with or without synchronous hiatus hernia repair with the use of magnetic bead prosthetic implant
LINX is a valid alternative to fundoplication in selected patients with symptomatic reflux with equivalent outcomes and safety
Anti-Reflux surgeons should be aware of LINX outcomes and limitations compared to fundoplication and advise patients if asked LINX providers should have received appropriate training and mentorship
Completion of 2-day industry In-Hospital Training program (Virtual) with expert LINX surgeons
Criteria for course
Performing anti-reflux and foregut surgeries regularly.
Performing a minimum of 10 laparoscopic fundoplication procedures (over the last 12 months).
Access & experience in pre-operative diagnostic work-up including OGD, pH monitoring, Manometry & Barium contrast study.
Works in collaboration with GI physician and multi-disciplinary team
Observe procedure where possible (COVID compliant)
Offer of proctorship to support first 2 cases using virtual technology to remote support during pandemic where face to face is not possible.
LINX providers should be performing >10 procedures per year
LINX should be offered as an alternative option to fundoplication surgery in eligible patients
- patients in whom the primary symptom is volume reflux/regurgitation
- a confirmed diagnosis of acid reflux and adequate symptom control with medical therapy but do not wish to continue with long term therapy
- patient with breakthrough symptoms despite maximum medical therapy
- a confirmed diagnosis of acid reflux and symptoms that respond to medical therapy but who are intolerant of medication side effects
- atypical symptoms such as aspiration, cough or hoarse voice and confirmed evidence of GORD (these patients as a group have less successful outcomes than patients with typical symptoms)
As minimum pass complex/equivocal patients through a hiatal MDT* prior to surgery, best practice to discuss all patients prior to surgery.

Minimum investigation set
High Resolution Manometry- Mean contractile amplitude of >30 mm Hg in 70% of swallows is recommended prior to magnetic sphincter augmentation
Other investigations to consider in patients with additional upper gastrointestinal symptoms such as bloating, nausea, vomiting, and early satiety: Contrast swallow/gastric emptying study
Atypical symptoms: ENT or respiratory opinion sort pre-operatively
