Measuring bowel length during hypo-absorptive surgeries like Roux-en-Y gastric bypass (RYGB) and Single Anastomosis Duodeno-ileal Sleeve (SADI-s) is controversial and usually abandoned due to the high risk of intestinal injury. However, some surgeons, especially in revisional surgery, prefer to count the whole bowel length to avoid leaving very short segments and severe malnutrition afterwards.
3D reconstructed CT scan can be useful in such conditions, avoiding the risk of intestinal injury, but accurate measures might be doubtful.
