American Board of Surgery Qualifying Exam (ABS QE) Practice Test

Laparoscopic sleeve gastrectomy is a bariatric surgical procedure that involves the removal of a large portion of the stomach, which limits food intake and promotes weight loss. Typically, patients can expect a significant amount of weight loss post-surgery.

The correct answer typically reflects the fact that patients often lose between 55-69% of their excess body weight within 12–18 months after the procedure. This range is supported by numerous studies that indicate the effectiveness of the sleeve gastrectomy in achieving substantial and sustained weight loss.

This procedure not only leads to physical changes but also contributes to hormonal changes that enhance metabolic responses which can facilitate weight loss. The outcomes may vary based on individual factors such as initial weight, adherence to dietary recommendations, and lifestyle changes.

Other ranges in the options do not accurately capture the average weight loss experienced by the majority of patients, as they either understate or overstate typical post-operative weight loss results seen in clinical practice.
