Summary

Roux-en-Y gastric bypass (RGB) revisions for complications or poor results lead to frequent major complications. These revisions offer negligible additional weight loss, making them not recommended for morbidly obese patients.

Aberrant expression and activation of insulin-like growth factor-1 receptor (IGF-1R) are mediated by an induction of IGF-1R promoter activity and stabilization of IGF-1R mRNA and contributes to growth factor independence and increased survival of the pancreatic cancer cell line MIA PaCa-2.

Area of Science:

  • Bariatric Surgery
  • Surgical Complications
  • Obesity Management

Background:

  • Roux-en-Y gastric bypass (RGB) is a common bariatric procedure for morbid obesity.
  • Technical issues and insufficient weight loss can necessitate reoperation after RGB.

Purpose of the Study:

  • To evaluate the outcomes of reoperation in patients who underwent Roux-en-Y gastric bypass.
  • To assess the complication rates and weight loss efficacy following RGB revisions.

Main Methods:

  • Retrospective analysis of 920 patients who underwent RGB over 10 years.
  • Detailed review of indications for reoperation, surgical procedures, and postoperative complications.

Main Results:

  • 42 patients (4.6%) required reoperation for reasons including dilated gastrojejunal anastomosis and inadequate weight loss.

  • Major complications occurred in 61.9% of patients after initial RGB and 50% after revision.
  • RGB revision was associated with high complication rates and minimal additional weight loss.

    • Conclusions:

    • Major postoperative complications can contribute to RGB failure.
    • Reoperation for technical failure or inadequate weight loss after RGB has a high complication rate and limited efficacy.
    • Repair of RGB for technical failure or complications is generally not recommended.
