Weight regain after gastric bypass can be reversed using the Bariatric Anastomotic Reduction System (BARS). This endoscopic system safely reduces enlarged gastrojejunal anastomosis, aiding in weight management.

Area of Science:

Bariatric surgery and endoscopic interventions.
Gastroenterology and weight management.

Background:

Roux-en-Y gastric bypass (RYGB) is effective but prone to significant weight regain (up to 63%).
Enlarged gastrojejunal anastomosis is a key factor contributing to post-RYGB weight regain.
The Bariatric Anastomotic Reduction System (BARS) is a novel endoscopic device for anastomotic reduction.

Purpose of the Study:

To evaluate the feasibility and effectiveness of the Bariatric Anastomotic Reduction System (BARS) for reducing enlarged gastrojejunal anastomosis.
To assess BARS as a treatment for weight regain after RYGB.

Main Methods:

The BARS device uses an endoscopic over-the-scope-clip system to reduce anastomosis size.
Six patients with >15% weight regain and enlarged gastrojejunostomy (>20mm) underwent the BARS procedure.

Keywords:

Bariatric reduction system anastomotic dilation

Procedures were performed using a single-channel endoscope with an external working channel.

Main Results:

All BARS procedures were completed safely without complications.
The mean procedure time was 52 minutes.
A mean weight loss of 6 kg was observed at 3-month follow-up.

Conclusions:

The Bariatric Anastomotic Reduction System (BARS) shows promise as an endoscopic solution for weight regain post-gastric bypass.
BARS effectively addresses enlarged gastrojejunal anastomosis, a common cause of weight regain.
