Interventional procedure overview of laparoscopic insertion of a magnetic ring for gastro-oesophageal reflux disease

When reported, studies were done in various countries and data relating to the UK context (Bonavina 2020) were included

There was 1 RCT (low risk of bias) which compared laparoscopic MSA with PPIs.

When comparing laparoscopic insertion of a magnetic ring with fundoplication, Zhuang (2021) included Nissen fundoplication, and Guidozzi (2019), Aiolfi (2018) and Bonavina (2020) included both total and partial fundoplication.

The longest follow up was a median of 9 years (Ferrari 2020). Two studies reported outcomes at 5 years or more (Zhuang 2021; DeMarchi 2021) and the remaining studies reported outcomes between 6 and 50 months.

There was variation in the population included, such as hiatal hernia size, GORD severity, oesophagitis severity, and presence of Barrett's oesophagus. There was some patient overlap between the studies.

There was variation in the procedural technique depending on the presence of hiatal hernia, the size of the hiatal defect, and the degree of hiatus hernia.

Device has evolved over time and different generations of the LINX Reflux Management System were used.

Length of hospital stay might be affected by different healthcare systems, such as in Germany, patients had longer stay built into reimbursement as shown in Bonavina (2020).
