Roux-en-Y gastric bypass (RYGBP) offers a favorable balance of risks and benefits for bariatric surgery patients. This study of over 2400 RYGBPs shows a low complication rate and significant long-term weight loss.

Area of Science:

  • Bariatric Surgery
  • Surgical Outcomes
  • Obesity Management

Background:

  • Evolution of bariatric procedures since the 1950s, including jejuno-ileal bypass (JIB), Roux-en-Y gastric bypass (RYGBP), and gastroplasty (GP).
  • Introduction of biliopancreatic diversion (BPD) and biliopancreatic diversion-duodenal switch (BPD-DS) in the 1980s.
  • Advancements in laparoscopic techniques and adjustable gastric bands in the 1990s.

Purpose of the Study:

  • To evaluate the long-term outcomes of open Roux-en-Y gastric bypass (RYGBP) performed by a single surgeon.
  • To compare the efficacy and safety of RYGBP with other bariatric procedures.
  • To provide insights into the selection of appropriate bariatric surgical approaches for individual patients.

Main Methods:

  • Retrospective analysis of over 2400 primary open RYGBP procedures performed between 1986 and March 2003.

  • Inclusion of a 7-year preceding experience with various gastroplasty procedures.
  • Assessment of major complications, re-operations, mortality rates, and excess weight loss.

    • Main Results:

    • Major complications requiring re-operations occurred in less than 2% of patients.
    • The mortality rate was 0.3%.
    • Mean excess weight loss at 10 years averaged 62%, demonstrating sustained efficacy.

    Conclusions:

    • Open RYGBP presents a reasonable compromise, offering a favorable balance of risks, benefits, and outcomes for most bariatric surgery candidates.
    • Individualized patient needs should guide the choice of operative procedures.
    • Discussion of the pros and cons of various bariatric approaches supports the conclusion regarding RYGBP's efficacy.
