Roux-en-Y Gastric Bypass Procedure: A Bariatric Surgical Procedure for Gastric Resectioning in Murine Model05:18

Roux-en-Y Gastric Bypass Procedure: A Bariatric Surgical Procedure for Gastric Resectioning in Murine Model

3.1K
This video describes a bariatric surgery-Roux-en-Y procedure. This involves the cutting of the jejunum- the middle portion of the intestine- to generate two intestinal limbs. The biliary limb is attached to the existing intestinal loop and the alimentary limb is attached to the stomach, creating a gastric bypass. The gastric bypass created here helps to decrease the nutrient uptake and efficiently reduces body...

Roux-en-Y gastric bypass (RYGB) is performed to treat obesity and diabetes. However, the mechanisms underlying RYGB's efficacy are not fully understood, and studies are limited by technical difficulty leading to high mortality in animal models. This article provides instructions on how to perform RYGB in rats with high success...

Bariatric surgery is the most efficient way to reduce body weight and the deadly metabolic complications (diabetes, obesity, and dyslipidemia) frequently associated with morbid obesity. Mouse models of bariatric surgery represent a unique asset for deciphering molecular mechanisms behind the beneficial effects of these surgeries on diabetes, hypertension, and...

One-anastomosis Gastric Bypass (OAGB) in Rats

11.4K
This protocol is for the performance of one-anastomosis gastric bypass (OAGB) on rat. The operator performs a long and tubular-stapled gastric pouch followed by hand-sewn anastomosis. For this model, the operator reproduces the same ratio between biliopancreatic and common limb in humans; therefore, the biliopancreatic limb measures 35 cm.

Summary
This summary is machine-generated.

Pancreatic head resections after Roux-en-Y gastric bypass (RYGB) are complex but do not increase patient morbidity. Surgeons can confidently manage these cases, as various reconstruction techniques show similar outcomes.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Bariatric Surgery

Background:

  • Pancreatic head resection is challenging in patients with altered anatomy post-Roux-en-Y gastric bypass (RYGB).
  • Optimal surgical management strategies for these unique cases require further investigation.

Purpose of the Study:

  • To identify optimal management decisions for pancreatic head resection in patients with prior RYGB.
  • To compare outcomes of pancreatic head resection in patients with and without prior RYGB.

Main Methods:

  • A multi-national, multi-center collaborative of 55 surgeons analyzed data from 96 patients who underwent pancreatic head resection after RYGB.
  • Propensity-score matched analysis compared these patients with 5533 patients without prior RYGB.
  • Operative details, reconstructive techniques, and perioperative outcomes were evaluated.

Main Results:

  • No significant differences in major postoperative outcomes were observed between RYGB and non-RYGB cohorts.
  • Twenty distinct reconstruction methods were used; the top three accounted for 52.1% without superior outcomes.
  • Remnant stomach management and the use of jejunostomy or gastrostomy tubes did not impact outcomes.

Conclusions:

  • Pancreatic head resection following RYGB presents unique challenges but does not lead to increased patient morbidity.
  • Current reconstructive techniques do not appear to offer distinct advantages in this patient population.
