Long-Term Outcomes of Magnetic Sphincter Augmentation: A Comparative Study to Nissen Fundoplication.

Background: Magnetic sphincter augmentation (MSA) demonstrates improvement in gastroesophageal reflux disease (GERD) across multiple short-term studies. Long-term, single-arm studies show durable outcomes, but there is limited comparative data to Nissen fundoplication (NF).

Methods: We performed a retrospective propensity-matched cohort study of patients with GERD undergoing MSA or NF between 2012 and 2018.

Laparoscopic revisional antireflux and hiatal hernia surgery results in a higher rate of complications and severity at 90 days than primary surgery.

Objective: Data on graded complications and their frequency after laparoscopic revisional antireflux and hiatal hernia surgery compared with primary surgery are lacking. We describe 30- and 90-day morbidity using the Clavien-Dindo classification.

Methods: A total of 298 patients underwent revision surgery between 2003 and 2020 and were propensity matched to primary surgeries (1:2 ratio) based on age, sex, body mass index, American Society of Anesthesiology classification, Los Angeles grade esophagitis, presence of Barrett's, and indication for surgery.

The classification of hiatal shapes and their use as a marker for complexity, operative interventions, and recurrence.

Background: Diaphragmatic reconstruction is a vital, but challenging component of hiatal hernia and antireflux surgery. Results are optimized by minimizing axial tension along the esophagus, assessed with intra-abdominal length, and radial tension across the hiatus, which has not been standardized. We categorized hiatal openings into 4 shapes, as a surrogate for radial tension, to correlate their association with operative interventions and recurrence.

Morbidity and mortality after antireflux and hiatal hernia surgery across a spectrum of ages.

Background: Antireflux surgery (ARS) and hiatal hernia repair (HHR) are common surgical procedures with modest morbidity. Increasing age is a risk factor for complications; however, details regarding acute morbidity are lacking. This study aimed to describe the incidence rates and types of morbidities across the spectrum of ages.
