The objective of this feasibility trial is to evaluate the Ethicon Endo-Surgery Endoscopic Suturing System (ESS) for tissue apposition and reduction of the size of a dilated GJ anastomosis in subjects who are regaining weight after successful weight loss following gastric bypass. Post-procedure weight will be followed to assess whether weight loss is resumed.

The ESS is an FDA-cleared (510(k)) sterile, single-use, disposable suturing system indicated for endoscopic placement of suture(s) and approximation of soft tissues. It is designed to facilitate endoscopic gastrointestinal procedures.

Accepts Healthy Volunteers:   Yes

Inclusion Criteria

Subjects must fulfill the following criteria to be entered in this study:

  • Review and sign informed consent;
  • Between 21 and 65 years of age (inclusive) at time of trial enrollment;
  • Documented Roux-en-Y Gastric Bypass (RYGB) surgery date
  • Documented baseline weight at the time of RYGB procedure;
  • > 12 months post RYGB);
  • Body mass Index (BMI) > 30 and at least 20 pounds in excess of post-RYGB weight nadir;
  • Patients initially achieved at least 50% excess weight loss (EWL) post RYGB;
  • Visible anastomotic junction (between gastric pouch and the Roux-limb);
  • Stoma size at screening > 15mm; and
  • Negative serum pregnancy test for women of childbearing potential.

Exclusion Criteria

Subjects will be excluded from the trial for any of the following:

  • Documented history of esophageal pathology (e.g., esophageal varices, Barrett's Esophagus);
  • American Anesthesia Association (ASA) Class IV or V and/or any contraindications to monitored anesthesia;
  • Documented history of GJ anastomosis stricture (within 6 months);
  • Documented history of previous RYGB revision;
  • Presence or documented presence of gastric/duodenal ulcers;
  • Presence of sepsis;
  • Medical or physical endoscopic contraindications, including esophageal varices or bleeding, laryngeal perforation, trauma to pharynx, aspiration pneumonia, acute peritonitis, and other conditions where general endoscopic techniques and/or placement of overtube are contraindicated;
  • Chronic Non-Steroidal Anti-Inflammatory Drug (NSAID) use (subjects taking a single aspirin tablet per day for cardioprotection are considered acceptable);
  • Uncontrolled diabetes;
  • Physical or psychological condition which would impair trial participation per investigator discretion;
  • Binge-eating or similar eating disorders;
  • Unable or unwilling to attend follow-up visits and examinations;
  • Concurrent surgical procedure (intra-operative exclusion during ESS procedure);
  • Participation in any other investigational device or drug trial within 30 days prior to enrollment; or
  • Any condition, which precludes compliance with the trial.
