About this trial

This is a spontaneous, prospective, monocentric, observational, cohort study, with the aim of evaluating the effect of ultrasound-guided endoscopic fundoplication using the Medigus Ultrasonic Surgical Endostapler (MUSESystem; MediGus, Ltd. Israel) in patients with esophageal or extra-esophageal gastro-oesophageal reflux disease (GERD)-related symptoms. The end of the study will be at the end of the 6-year follow-up of the last patient enrolled. The study proposes the following objectives:

* Primary objective: to evaluate the efficacy of endoscopic fundoplication with MUSE for the treatment of GERD, through clinical experience, in terms of:

* effect on GERD-Health Related Quality of Life (HRQL) and Reflux Symptom Index (RSI) questionnaire scores * effect on the use and dosage of proton pump inhibitors (PPI) * feasibility and safety of the endoluminal fundoplication procedure * Secondary objective: to characterize the treated patient population (demographic and objective data) and to identify the successful predictors of the procedure.

The study design includes the following phases:

\*Preliminary patient evaluation and verification of inclusion criteria through: Upper GI endoscopy Esophageal high-resolution manometry 24-hours esophageal pH-impedance OFF PPI PPI use GERD-HRQL and RSI questionnaires scores OFF PPI

* 6-month follow-up: Upper GI endoscopy Esophageal high-resolution manometry 24-hours esophageal pH-impedance OFF PPI PPI use GERD-HRQL and RSI questionnaires scores OFF PPI * 12-months follow-up: Upper GI endoscopy 24-hours esophageal pH-impedance OFF PPI PPI use GERD-HRQL and RSI questionnaires scores OFF PPI * Yearly clinical follow-up (up to 6 years):

PPI use GERD-HRQL and RSI questionnaires scores OFF PPI

Treatments tested in this trial

  • Endoscopic fundoplication

    Device

    Endoscopic fundoplication is a less invasive alternative to the traditional surgical fundoplication. The MUSE device is similar to an endoscope, so the whole procedure can be done by a single operator. The device is composed of a shaft with a distal rigid part which is placed in the esophagus 3 cm proximal to the esophago-gastric junction containing a cartridge holding five B-shaped titanium surgical Staples and a tip which is retroflexed and contains an ultrasonic transducer which defines the correct tissue thickness for stapling the fundus against the esophagus. The device must be extracted to be reloaded with 5 more staples at a time for creation of a 180° anterior fundoplication.

Trial outcomes

Primary outcomes

1

To evaluate clinical efficacy of endoscopic fundoplication with MUSE as assessed by change in GERD-HRQL (Gastro-esophageal Reflux Disease-Health Related quality of life) questionnaire score

GERD-HRQL is a validate questionnaire to evaluate GERD-related esophageal symptoms. The scale range is (0-50); the higher values represents worse outcomes.

Time frame
change from baseline GERD-HRQL at 6 months
2

To evaluate clinical efficacy of endoscopic fundoplication with MUSE as assessed by change in GERD-HRQL (Gastro-esophageal Reflux Disease-Health Related quality of life) questionnaire score

GERD-HRQL is a validate questionnaire to evaluate GERD-related esophageal symptoms. The scale range is (0-50); the higher values represents worse outcomes.

Time frame
change from baseline GERD-HRQL at 12 months
3

To evaluate clinical efficacy of endoscopic fundoplication with MUSE as assessed by change in GERD-HRQL (Gastro-esophageal Reflux Disease-Health Related quality of life) questionnaire score

GERD-HRQL is a validate questionnaire to evaluate GERD-related esophageal symptoms. The scale range is (0-50); the higher values represents worse outcomes.

Time frame
change from baseline GERD-HRQL at 24 months
4

To evaluate clinical efficacy of endoscopic fundoplication with MUSE as assessed by change in GERD-HRQL (Gastro-esophageal Reflux Disease-Health Related quality of life) questionnaire score

GERD-HRQL is a validate questionnaire to evaluate GERD-related esophageal symptoms. The scale range is (0-50); the higher values represents worse outcomes.

Time frame
change from baseline GERD-HRQL at 3 years

Secondary outcomes

1

To identify endoscopic factors predicting positive outcomes: changes in hiatal hernia size

Endoscopic fundoplication with MUSE modifies the anatomy of the esophago-gastric junction to reduce the reflux of gastric contents into the esophagus. The size of a hiatal hernia is a parameter describing the continence characteristics of the sphincter neo-valve.

Time frame
change from baseline hiatal hernia size at 6 months
2

To identify endoscopic factors predicting positive outcomes: changes in hiatal hernia size

Endoscopic fundoplication with MUSE modifies the anatomy of the esophago-gastric junction to reduce the reflux of gastric contents into the esophagus. The size of a hiatal hernia is a parameter describing the continence characteristics of the sphincter neo-valve.

Time frame
change from baseline hiatal hernia size at 12 months
3

To identify endoscopic factors predicting positive outcomes: changes in Hill's grade

Endoscopic fundoplication with MUSE modifies the anatomy of the esophago-gastric junction to reduce the reflux of gastric contents into the esophagus. The Hill's grade is a parameter describing the continence characteristics of the sphincter neo-valve. The Hill's grade range from I to IV; the higher grades represents worse outcomes (worse valve's continence).

Time frame
change from baseline Hill's grade at 6 months

Endoscopic fundoplication with MUSE modifies the anatomy of the esophago-gastric junction to reduce the reflux of gastric contents into the esophagus. The Hill's grade is a parameter describing the continence characteristics of the sphincter neo-valve. The Hill's grade range from I to IV; the higher grades represents worse outcomes (worse valve's continence).
