This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether the size of a calibration tube used during laparoscopic sleeve gastrectomy — a weight-loss surgery that removes part of the stomach — affects how often patients develop leaks along the surgical seams after surgery. Researchers will compare two tube sizes: a larger 48-Fr tube versus the standard smaller tubes (34, 36, or 38-Fr) that surgeons typically use. The goal is to see if the larger tube reduces complications while still helping patients lose weight long-term.
Sleeve gastrectomy is an increasingly common weight-loss surgery, but one serious complication is a leak along the staple line where the stomach is sealed — this happens in about 3 out of 100 patients and can require long and difficult treatment. Early research suggests that using a larger calibration tube might lower the risk of these leaks, so this trial will test whether that's true.

If you join this trial, you will be randomly assigned to receive laparoscopic sleeve gastrectomy using either the larger 48-Fr calibration tube or the standard-size tube. The surgery itself is performed the same way — the only difference is the tube size used to shape and measure your new, smaller stomach. After surgery, your surgical team will monitor you for any complications, particularly leaks along the staple line, and will track your weight loss over the following months to compare outcomes between the two groups.
