Small Intestine Length Measurement Using 3D CT Volumetry and in Vivo Measurement Using Pre-marked Graspers in Revisional Bariatric Surgeries. a Comparative Study

Recruiting

• Conditions: Small Intestine Length

• Registration Number: NCT06696677
• Lead Sponsor: Kasr El Aini Hospital

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Accurate small bowel length	about 6 months	the aim of the study to assess if the CT scan with 3D reconstruction will give accurate measures for the bowel length compared to the marked graspers used in laparoscopic surgery

Secondary Outcome Measures

Name	Time	Method
Operative time	intraoperative	measuring the whole bowel length may increase the operative time according to the skills of the surgeon, the presence of adhesions, and short mesentery.
Intestinal Injury	up to 6 months	counting the whole bowel length is a tedious procedure, especially in patients with obesity, where the mesentery is dense and may cause injury to the bowel.; In this study, we will assess the incidence of intestinal injury of the small bowel, detected intra-operatively or post-operatively.
