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.

Outcome Measures

Primary Outcomes (1)

  • Accurate small bowel length

    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

    about 6 months

Secondary Outcomes (2)

  • Operative time

    intraoperative

  • Intestinal Injury

    up to 6 months

Study Arms (2)

Marked Laparoscopic graspers group

ACTIVE COMPARATOR

in this arm, the graspers will be marked by a sterile tape, 5 cm in length. This will help for accurate measuring of the whole intestine.

Procedure: Measuring the small instestine length using pre-marked laparoscopic graspers

3D CT scan group

ACTIVE COMPARATOR

In this arm, all patients involved in the study will have a pre-operative CT scan, for which a 3D reconstruction will be done and measure the whole small intestinal length.

Diagnostic Test: CT

Interventions

CTDIAGNOSTIC_TEST

CT measurment of small bowel

3D CT scan group

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.

SINGLE GROUP
Model Details: This is a prospective cross-sectional analytic study designed to compare two methods of small bowel length measurement: preoperative 3D CT volumetry and intraoperative laparoscopic measurement using pre-marked graspers. The study will include adult patients undergoing revisional bariatric surgeries at Kasr AlAiny Hospitals. All participants will undergo preoperative imaging and intraoperative measurements, with results analyzed to determine the accuracy and correlation between the two methods.
