Kasr El Aini Hospital

Status: Enrolling

Conditions: Small Intestine Length

Treatments: Diagnostic Test: CT; Procedure: Measuring the small instestine length using pre-marked laparoscopic graspers

About

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.

Enrollment: 30 estimated patients

Sex: All

Ages: 16 to 70 years old

Inclusion criteria

• Patients who are candidates for revisional bariatric surgery
• Patients consenting to participate in the study.

Exclusion criteria

• Patients with severe adhesions where measuring the small bowel may expose them to unnecessary injuries.
• Patients refusing to participate in the study.
• Patient refusing CT scan to be done pre-operatively.

Trial design

Primary purpose: Diagnostic

Allocation: Non-Randomized

Interventional model: Single Group Assignment

Masking: Single Blind

---

30 participants in 2 patient groups

Marked Laparoscopic graspers group

Active Comparator group

Description:

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.

Treatment:

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

3D CT scan group

Active Comparator group

Description:

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.

Treatment:

Diagnostic Test: CT
