The aim of this study was to evaluate the efficacy of heparin-bonded vascular grafts to offer improved outcomes compared with standard prosthetic grafts in access surgery. A systematic review and meta-analysis was performed and eight studies (seven observational studies and one randomized controlled trial) were included. The pooled 6-month and 1-year primary patency was not significantly different between heparin-bonded arteriovenous (AV) grafts and standard prosthetic AV grafts in seven studies reporting on 1,209 access procedures. The assisted primary patency and secondary patency at 1-year was not significantly different either. Heparin-bonded AV grafts offer no distinct advantage over standard prosthetic AV grafts and their preferential use in access surgery cannot be recommended based on the available evidence.

Roux-en-Y Intussusception: A Case Report.
Cureus
January 2025
General Surgery, Tampa General Hospital Brooksville, Brooksville, USA.
Roux-en-Y gastric bypass (RYGB) is a bariatric surgical procedure commonly performed in adults to treat severe obesity. While RYGB is generally safe, it occasionally leads to rare but significant complications, including intussusception, a form of bowel obstruction caused by the invagination of an intestine segment from the proximal to the adjacent distal portion. We report a case of intussusception in a 74-year-old female patient who underwent RYGB 12 years prior.
