Long-term objective hiatal hernia recurrence after magnetic sphincter augmentation versus laparoscopic fundoplication: a multicenter cohort study of moderate and large hiatal hernias.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRecurrent hiatal hernia is a leading cause of long-term failure after antireflux surgery and the most common indication for revisional surgery. Although magnetic sphincter augmentation (MSA) has demonstrated favorable outcomes following repair of moderate and large hiatal hernias, its long-term anatomical durability compared with laparoscopic fundoplication remains unclear. We compared the durability of hiatal hernia repair following MSA versus fundoplication in patients with moderate and large hiatal hernias using objective assessment of postoperative hiatal hernia recurrence.
methodsThis multicenter observational cohort study analyzed prospectively maintained registries from six high-volume foregut centers. Adult patients undergoing primary repair of moderate (3-5 cm) or large (> 5 cm or paraesophageal) hiatal hernias with MSA or laparoscopic fundoplication who underwent protocol-directed objective follow-up 3 years after surgery were included. The primary outcome was objective hiatal hernia recurrence. Secondary outcomes included GERD-HRQL, proton pump inhibitor use, patient satisfaction, and revisional surgery.
resultsA total of 258 patients underwent antireflux surgery, including 196 (76.0%) treated with MSA and 62 (24.0%) with fundoplication. At 3 years, objective hiatal hernia recurrence was significantly lower following MSA than fundoplication (6.1% vs 21.0%; P = 0.002). On multivariable analysis, fundoplication was significantly associated with 3-year objective hiatal hernia recurrence (OR, 4.67; 95% CI, 1.11-19.59; P = 0.035). Despite lower recurrence after MSA, GERD-HRQL, dysphagia, bloating, patient satisfaction, and revisional surgery rates were similar between groups, whereas postoperative proton pump inhibitor use was lower following MSA (11.5% vs 27.5%; P = 0.022).
conclusionsMSA was associated with lower objective hiatal hernia recurrence than laparoscopic fundoplication, but patient-reported outcomes were similar between procedure groups. Long-term anatomical durability should be considered alongside patient-reported outcomes when selecting the optimal antireflux procedure.
