Long-Term Satisfaction and Medication Dependence After Antireflux Surgery

The Use of Standardized Measures to Predict and Assess Quality of Life after Laparoscopic Hiatal Hernia Repair

The literature regarding laparoscopic hiatal hernia repair is difficult to interpret because of inconsistencies in describing hernia characteristics and outcome measures. This study was performed to evaluate risk factors for an unsatisfactory outcome after repair using objective definitions of hernia size and a clinically relevant outcome instrument. A retrospective review of a prospectively maintained database was conducted over a seven-year period. Data collected included patient demographics and hernia-related variables. Outcomes were defined using a validated quality of life (QOL) instrument. Postoperatively, the mean total QOL score decreased from 22.9 to 5.8 (P < 0.001). In all, 13.8 per cent of patients had unsatisfactory QOL scores postoperatively. Multivariate analysis showed that high gastroesophageal (GE) junction position (P = 0.03) and female gender (P = 0.02) were the only significant factors associated with an unsatisfactory postoperative QOL. Laparoscopic hiatal hernia repair significantly improves QOL. With respect to predicting clinically relevant outcomes, hernias are best characterized by the position of the GE junction. Females with high GE junction position are at the highest risk for an unsatisfactory outcome.

Magnetic Sphincter Augmentation with the LINX Device for Gastroesophageal Reflux Disease after U.S. Food and Drug Administration Approval

Magnetic sphincter augmentation (MSA) of the gastroesophageal junction with the LINX Reflux Management System is an alternative to fundoplication for gastroesophageal reflux disease (GERD) that was approved by the U.S. Food and Drug Administration (FDA) in March 2012. This is a prospective observational study of all patients who underwent placement of the LINX at two institutions from April 2012 to December 2013 to evaluate our clinical experience with the LINX device after FDA approval. There were no intraoperative complications and only four mild postoperative morbidities: three urinary retentions and one readmission for dehydration. The mean operative time was 60 minutes (range, 31 to 159 minutes) and mean length of stay was 11 hours (range, 5 to 35 hours). GERD health-related quality-of-life scores were available for 83 per cent of patients with a median follow-up of five months (range, 3 to 14 months) and a median score of four (range, 0 to 26). A total of 76.9 per cent of patients were no longer taking proton pump inhibitors. The most common postoperative complaint was dysphagia, which resolved in 79.1 per cent of patients with a median time to resolution of eight weeks. There were eight patients with persistent dysphagia that required balloon dilation with improvement in symptoms. MSA with LINX is a safe and effective alternative to fundoplication for treatment of GERD. The most common postoperative complaint is mild to moderate dysphagia, which usually resolves within 12 weeks.
