Complications After Paraesophageal Hernia Repair.

Paraesophageal hernia repair (PEHR) is a challenging operation both technically and because the affected patient population is typically older with more comorbidities. As a result, PEHR is associated with substantial morbidity. Morbidity and mortality following PEHR vary significantly depending on the acuity of the operation and size of the hernia.

Efficacy of gastric stimulator as an adjunct to pyloroplasty for gastroparesis: characterizing patients suitable for single procedure vs dual procedure approach.

Background: Pyloroplasty is an effective surgery for gastroparesis. However, some patients fail to improve after pyloric drainage and may require subsequent gastric electric stimulation. There is a paucity of data on the efficacy of gastric stimulator as an adjunct to failed pyloroplasty.

Magnetic Sphincter Augmentation for Laryngopharyngeal Reflux: An Assessment of Efficacy and Predictors of Outcome.

Introduction: Magnetic sphincter augmentation (MSA) is an effective treatment for typical reflux symptoms, but data on its impact on laryngopharyngeal reflux (LPR) is limited. This study aimed to determine the efficacy of MSA for LPR and to identify predictors of outcome.

Methods: This was a retrospective review of 775 patients who underwent MSA between 2013 and 2021.

Impact of Change in Sizing Protocol on Outcome of Magnetic Sphincter Augmentation.

Objective: To evaluate and compare magnetic sphincter augmentation (MSA) device sizing protocols on postoperative outcomes and dysphagia.

Summary Background Data: Among predictors of dysphagia after MSA, device size is the only factor that may be modified. Many centers have adopted protocols to increase device size.

Esophageal body adaptation to Nissen fundoplication: Increased esophagogastric outflow resistance yields delayed and sustained peristaltic contractions without increased amplitude.

Background: Improvement in lower esophageal sphincter (LES) competency after laparoscopic Nissen fundoplication (LNF) is well established, yet esophageal body physiology data are limited. We aimed to describe the impact of LNF on whole esophagus physiology using standard and novel manometric characteristics.

Methods: A cohort of patients with an intact fundoplication without herniation and no postoperative dysphagia were selected and underwent esophageal manometry at one-year after surgery.
