Clinical Scorecard: Long-term Objective Assessment of Hiatal Hernia Recurrence Following Magnetic Sphincter Augmentation Versus Laparoscopic Fundoplication

At a Glance

Key Highlights

• The study compared objective hiatal hernia recurrence after MSA and laparoscopic fundoplication for moderate (3–5 cm) or large (>5 cm or paraesophageal) hernias.
• Objective recurrence was defined as more than 2 cm of the stomach, fundoplication wrap, or MSA device above the diaphragm on contrast esophagram or upper endoscopy.
• Eligibility required objective postoperative assessment at 3 years; contrast esophagram was used for assessment at approximately 3 or 5 years, with endoscopy used when esophagram was unavailable.
• Secondary outcomes included GERD-related quality of life, proton pump inhibitor use, patient satisfaction, and revision surgery for recurrent hernia.
• Procedure choice was not protocolized and was guided by anatomy, esophageal physiology, operative era, and surgeon preference.

Guideline-Based Recommendations

Diagnosis

• For this study, recurrence was assessed objectively using contrast esophagram or upper endoscopy.
• Baseline hernia size was classified from intraoperative findings as moderate (3–5 cm) or large (>5 cm or paraesophageal).

Management

• Both study procedures included laparoscopic hernia reduction and crural repair.
• Fundoplication consisted of complete (360°) or partial (180° or 270°) wraps; MSA was implanted using previously described sizing and placement methods.

Monitoring & Follow-up

• Eligibility required objective postoperative assessment at 3 years. Contrast esophagram assessed hiatal repair at approximately 3 or 5 years; when esophagram was unavailable, the operating surgeon assessed recurrence by upper endoscopy.
• Secondary outcomes included GERD-HRQL, proton pump inhibitor use, patient satisfaction, and revision surgery for recurrent hernia.

Risks

• The article identifies recurrent hiatal hernia as a major mechanism underlying procedural failure and a predominant indication for revisional antireflux surgery.
• The article notes that objective anatomical recurrence can occur even when patient-reported outcomes remain favorable.

Patient & Prescribing Data

The cohort screened adults undergoing primary laparoscopic hiatal hernia repair with MSA or fundoplication for hernias of at least 3 cm; exclusions included revisional procedures, hernias under 3 cm, and absent objective follow-up at 3 years.

MSA and fundoplication were compared in an observational cohort. Procedure selection was based on patient anatomy and esophageal physiology, operative era, and surgeon preference rather than a study protocol.

Clinical Best Practices

• The study defined objective recurrence as more than 2 cm of stomach, wrap, or MSA device above the diaphragm on esophagram or endoscopy.
• Interpret comparative findings in light of the observational design and non-protocolized procedure selection.
• The study assessed objective anatomical recurrence separately from symptom-based outcomes.
