Patients undergoing bariatric surgery for GERD may very often require revision surgery
Gastroesophageal reflux disease (GERD) is a recognized possible outcome of bariatric surgery and may necessitate revisional surgery.
In a recent study published in Surgical Endoscopy, researchers said GERD is the second most common reason for revisional surgery after bariatric surgery, primarily affecting sleeve gastrectomy (SG) patients who mainly underwent Roux-en-Y gastric bypass (RYGB) revision. They mentioned further investigation is needed to optimize these patients' pre-operative approaches and surgical strategies.
Our understanding of the population needing revision needs to be improved. This study aims to characterize GERD patients requiring revisional surgery, understand their perioperative risks, and identify strategies for improved outcomes.
In 2020, a retrospective cohort of GERD patients needing revisional surgery was identified using the MBSAQIP registry. Multivariable logistic regression was used to examine correlations between baseline characteristics and morbidity.
Key findings from this study are:
· 4412 patients required revisional surgery for GERD, encompassing 24% of all conversion procedures.
· Most patients underwent SG as their original surgery, constituting 80.1%.
· The revisional surgery for most patients was RYGB, constituting 84.4%.
· 527 patients experienced major complications.
· Ten patients died within 30 days of revisional surgery.
· Major complications included anastomotic leak (0.70%) and gastrointestinal bleeding (0.86%).
· Operative length, pre-operative antacid use, and RYGB were predictors of major complications.
This study is the largest to date on patients undergoing revisional surgery for GERD. The pathophysiology of GERD in bariatric surgery patients is still debated, but a better understanding could reduce the need for revisional procedures. They said that novel endoscopic techniques raise new questions as potential alternatives for primary and revisional bariatric procedures.
