Hospitalization rates more than doubled after Roux-en-Y gastric bypass (RYGB) surgery. Post-RYGB admissions were often for complications, unlike pre-surgery admissions for obesity or elective procedures.
Area of Science:
- Bariatric surgery outcomes
- Gastrointestinal surgery research
- Obesity treatment effectiveness
Background:
- Roux-en-Y gastric bypass (RYGB) is effective for obesity and comorbidities.
- Inpatient service utilization post-RYGB requires further understanding.
Purpose of the Study:
- To determine rates and indications for inpatient hospital use before and after RYGB.
- To analyze trends in hospitalization following bariatric surgery.
Main Methods:
- Retrospective analysis of RYGB patients in California (1995-2004).
- Examined hospitalizations in the 1-3 years preceding and following RYGB.
- Utilized multivariate logistic regression to identify readmission predictors.
Main Results:
- Hospitalization rates more than doubled post-RYGB (19.3%) compared to pre-RYGB (7.9%).
- Common post-RYGB admissions included ventral hernia and gastric revisions, unlike pre-RYGB obesity-related issues.
- Higher Charlson Comorbidity Index and prior hospitalizations predicted 1-year readmission.
Conclusions:
- Increased hospital use post-RYGB appears directly related to the procedure.
- Significant rehospitalization rates necessitate consideration by payers, clinicians, and patients.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
