Study Details

Study Description

Brief Summary

Objectives of the Study:

The primary objective of this study is to evaluate the relative merits, safety and effectiveness of the tailored TIF2 procedure in treating GERD patients who have persistent GERD symptoms despite PPI therapy.

The secondary objective of the study is to evaluate the effectiveness of the tailored TIF procedure in restoring the antireflux barrier and eliminating GE reflux.

Type of Study:

Prospective, non-randomized, uncontrolled Study Duration 12 months Number of Patients 20

Inclusion Criteria:

Age 18-70 years, on daily PPIs for > 6 months, persistent GERD symptoms despite PPI therapy, anatomic disruption of the gastroesophageal valve to a Hill Grade II-III, evidence of one of the following while on PPI therapy: (1) erosive esophagitis (erosions or ulcerations during endoscopy); (2) abnormal ambulatory pH study; or (3) biopsy confirmed changes characteristic of reflux esophagitis; acceptable esophageal motility (by either manometry or video esophagogram), hiatal hernia no larger than 2 cm, patient willing to cooperate with post-operative dietary recommendations and assessment tests, signed informed consent

Exclusion Criteria:

BMI > 40, hiatal hernia > 2 cm, esophagitis grade D, esophageal ulcer, fixed esophageal stricture, gastric motility disorders, previous splenectomy, pregnancy (female), immunosuppression, ASA > 2, portal hypertension and/or varices, history of previous resective gastric or esophageal surgery, cervical spine fusion, Zenker's diverticulum, esophageal epiphrenic diverticulum, achalasia, scleroderma or dermatomyositis, eosinophilic esophagitis, or cirrhosis, active gastro-duodenal ulcer disease, gastric outlet obstruction or stenosis, gastroparesis or delayed gastric emptying, coagulation disorders

Interventions:

Treatment: Tailored transoral incisionless fundoplication (TIF2) using EsophyX system with SerosaFuse fasteners (EndoGastric Solutions, Inc., Redmond, WA, USA)

Evaluation Criteria:

Primary Outcome Measure 24 hour pH impedance study: change in Johnson DeMeester scores; GERD-HRQOL scores Secondary Outcome Measures PPI usage, GERD symptoms at 6 and 12 months vs. baseline off PPI's, total number of reflux episodes, and Symptom Association Probability while off PPI.

Safety: Adverse events will be mapped to standard terms and reported.

Outcome Measures

Primary Outcome Measures

  1. 24 hour pH impedance study: change in Johnson DeMeester scores; GERD-HRQOL scores [1, 3, 6, 12 month]

Secondary Outcome Measures

  1. PPI usage, GERD symptoms at 6 and 12 months vs. baseline off PPI's, total number of reflux episodes, and Symptom Association Probability while off PPI. Safety: Adverse events will be mapped to standard terms and reported. [1 day; 1 week; 1, 3, 6, 12 month]
