Higher volume at teaching hospitals is a contributing factor to these differences in outcomes. The findings suggest that hospital structure and process variables play a role in variation in surgical outcomes.
A study of patients undergoing Roux-en-Y gastric bypass found significant complications and increased risk of obesity-related health issues. The procedure requires major lifestyle changes and can be fraught with complications, highlighting the importance of weighing risks and benefits before surgery.
A study of 335 patients found that gastric bypass surgery is associated with complications such as suture tears, pulmonary embolism, and pneumonia.

The new method minimizes blood loss and is well-tolerated by patients, making it an ideal approach for those too ill to undergo standard surgery.
A new study by Johns Hopkins researchers found that African Americans who undergo carotid endarterectomy (CEA) have worse outcomes than whites due to the operation being performed in less experienced hands. The study suggests that socioeconomic factors are influential in determining surgical outcome, rather than genetic differences.
A new Cornell University study found that surgeons performing carotid endarterectomies who got their licenses 20 or more years ago had the highest mortality rate among their patients. The study also found a relation between the mortality of endarterectomy patients and the number of times surgeons performed the procedure.
