Straight or oblique: which approach holds up over time

Not all rib remodeling is performed the same way. This study compares two approaches — straight and oblique — in 240 patients, measuring not only how much the waist reduces but how long the reduction lasts. The oblique approach was associated with lower recurrence and a shorter operative time.

The question few studies ask: and afterwards?

Most studies measure outcomes at 3 or 6 months. This one introduces a different variable: recurrence, defined as an increase in abdominal circumference during follow-up.

It is the question that matters to a patient: not how much the waist drops in a month, but whether it holds at a year.

Age, weight, body mass index and abdominal circumference were recorded before surgery. Circumference was measured again immediately after and at 3, 6 and 12 months. Baseline characteristics were comparable between groups.

The result

The oblique approach was associated with a shorter operative time, and the authors conclude it provides «more durable waist circumference reduction with lower recurrence rates».

This is a retrospective study: existing records were analysed, with no random assignment. That limits the comparison, since there may be unmeasured differences between those who received one approach or the other. At 240 patients with 12-month follow-up, it is among the larger series comparing variants of the technique.

The technique's creator is first author. This is not an independent study.
