More than a mechanical problem: Dysphagia and new-onset ineffective esophageal motility after LINX® placement—a case report
Abstract
Introduction Magnetic sphincter augmentation (MSA) with the LINX® device is an effective surgical option for gastroesophageal reflux disease (GERD), offering benefits such as preservation of belching and reduced gas bloat syndrome compared to Nissen fundoplication. However, postoperative dysphagia is common complication, occurring in approximately 15–30 % of patients. Case presentation We report the case of a 66-year-old female who underwent laparoscopic hiatal hernia repair with concurrent LINX® device placement for GERD. Three weeks postoperatively, she developed progressive dysphagia that was initially responsive to corticosteroids but recurred. Barium swallow demonstrated mild narrowing at the gastroesophageal junction. Despite three serial endoscopic dilations, her symptoms persisted. High-resolution manometry (HRM) revealed new-onset ineffective esophageal motility (IEM), in contrast to her preoperative study, which showed normal esophageal peristalsis. The LINX device was surgically removed due to refractory symptoms. Post-removal, the patient experienced significant symptomatic improvement. Repeat HRM one year later showed improved motility findings. Discussion This case illustrates the potential for MSA to contribute to the development of esophageal dysmotility in patients with subtle or predisposing motility abnormalities. Early postoperative dysphagia should prompt repeat manometric evaluation and consideration of device removal in refractory cases. Conclusion MSA…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
