Overview
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.
Interventions
- Diagnostic test CT
CT measurment of small bowel - Procedure Measuring the small instestine length using pre-marked laparoscopic graspers
Intra-operatively, the surgeon will assess the length of the small intestine using a 5-cm marked laparoscopic graspers to accurately assess the whole small intestine length.
Primary outcome measures
- Accurate small bowel length [Time frame: about 6 months]
Secondary outcome measures (2)
- Operative time [Time frame: intraoperative]
- Intestinal Injury [Time frame: up to 6 months]
