Managing medical and surgical disorders after divided Roux-en-Y gastric bypass surgery.

Authors:
Bikram Bal Timothy R Koch Frederick C Finelli Michael G Sarr

Nat Rev Gastroenterol Hepatol 2010 Jun 11;7(6):320-34. Epub 2010 May 11.

Section of Gastroenterology, Washington Hospital Center and Georgetown University School of Medicine, Washington, DC 20010, USA.

The National Longitudinal Study of Adolescent Health and the National Health and Nutrition Examination Survey reported that over 40% of the US population is overweight. The average weight loss attained by medical management programs is neither sufficient nor durable enough to treat medically complicated obesity. An estimated 220,000 bariatric procedures are performed yearly in the USA and Canada. The divided Roux-en-Y gastric bypass (RYGB) is performed most commonly in these countries and is considered the gold standard bariatric surgical procedure. The complexity of RYGB means that serious and potentially preventable perioperative complications can occur. RYGB alters the normal anatomy and physiology of the upper gut, which has predictable adverse effects and potential complications. Patients seek advice and care for symptoms that develop or persist after RYGB; although some symptoms are expected and predictable, others are complications that may or may not require active medical or surgical intervention. Physicians should be able to predict and manage most postoperative medical and nutritional disorders related to RYGB and should be prepared to assess patients for potential referral for surgical intervention or revision.

Three-Year Outcomes of Sleeve Gastrectomy Plus Jejunojejunal Bypass: a Retrospective Case-Matched Study with Sleeve Gastrectomy and Gastric Bypass in Chinese Patients with BMI ≥35 kg/m.

Authors:
Shibo Lin Cong Li Wei Guan Hui Liang

Obes Surg 2021 Apr 16. Epub 2021 Apr 16.

Department of General surgery, the First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing, 210029, Jiangsu, China.

Background: Sleeve gastrectomy plus jejunojejunal bypass (SG+JJB) is a novel bariatric procedure. In this study, we compared the 3-year outcomes of SG+JJB to those of sleeve gastrectomy (SG) and gastric bypass (RYGB).

Methods: This retrospective study included 113 patients (SG, N=31; RYGB, N=33; SG+JJB, N=49) with a preoperative BMI≥35 kg/m. Read More

Impact of bariatric surgery on gastroesophageal reflux disease and esophageal motility.

Authors:
Anh D Nguyen

Curr Opin Gastroenterol 2021 Apr 14. Epub 2021 Apr 14.

Division of Gastroenterology and Center for Esophageal Diseases, Baylor University Medical Center, and the Center for Esophageal Research, Baylor Scott & White Research Institute, Dallas, Texas, USA.

Purpose Of Review: Obesity is rapidly increasing in prevalence, and bariatric surgery has become a popular treatment option that can improve all-cause mortality in obese individuals. Gastroesophageal reflux disease (GERD) and esophageal motility disorders are common in the obese population, and the effects of bariatric surgery on these conditions differ depending on the type of bariatric surgery performed.

Recent Findings: Laparoscopic adjustable gastric banding has declined in popularity due to its contributions to worsening GERD symptoms and the development of esophageal dysmotility. Read More

Mauricio Gonzalez-Urquijo Mario Zambrano-Lara Jose Andres Patiño-Gallegos Mario Rodarte-Shade Adolfo Leyva-Alvizo Javier Rojas-Mendez

Surg Obes Relat Dis 2021 Mar 9. Epub 2021 Mar 9.

Tecnologico de Monterrey, School of Medicine and Health Sciences, Monterrey, México. Electronic address:

Background: Bariatric surgery has been a popular way for many women to reach a healthy body mass index, and as a consequence, a decreased body mass, which causes a greater chance of fertility, with improved pregnancy and better maternal outcomes.

Objective: Describe a single-center experience of pregnancies complicated by internal hernias after gastric bypass.

Setting: Academic Medical Center. Read More

RYGB Is More Effective than VSG at Protecting Mice from Prolonged High-Fat Diet Exposure: An Occasion to Roll Up Our Sleeves?

Authors:
Matthew Stevenson Ankita Srivastava Jenny Lee Christopher Hall Thomas Palaia Raymond Lau Collin Brathwaite Louis Ragolia

Obes Surg 2021 Apr 15. Epub 2021 Apr 15.

Department of Biomedical Research, NYU Long Island School of Medicine, NYU Langone Hospital-Long Island, 101 Mineola Blvd. Suite 4-003, Mineola, NY, 11501, USA.

Purpose: Understanding the effects of Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) on adipose tissue physiology is important for the treatment of obesity-related metabolic disorders. By using robust mouse models of bariatric surgery that closely resemble those performed in humans, we can compare the effects of RYGB and VSG on adipose physiology in the absence of post-operative confounds such as diet and lifestyle changes.

Materials And Methods: RYGB and VSG were compared using a diet-induced mouse model of obesity. Read More
