Gastric Ultrasound After Bariatric Surgery

This study is looking at how to best use ultrasound to see the stomach in people who have had weight-loss surgery (bariatric surgery). The goal is to learn how bariatric surgery changes the stomach's position and how to get clear ultrasound images. This is important for doctors, especially anesthesiologists, to check stomach fullness and reduce the risk of food or liquid going into the lungs (aspiration) during surgery. You might be able to join if you are between 18 and 85 years old, are scheduled for bariatric surgery, and haven't had previous abdominal surgery. The study will measure the distance from the stomach to the abdominal wall and the size of a part of the stomach (gastric antrum Cross-sectional area or CSA) right after your surgery and two hours later. The study is currently unclear on its status and plans to enroll 10 participants.

Study design
This is a non-randomized study that will look at 10 participants. It aims to describe how to image the stomach after bariatric surgery.
What's involved
You would have your stomach imaged with an ultrasound while you are under general anesthesia for your bariatric procedure, both before and after the surgery.
Compensation
Not stated in the trial record.
Follow-up
Measurements will be taken at the end of your procedure and two hours after the procedure starts on the day of surgery.

What this trial measures

  • Change in distance from peritoneal wallend of the individual's procedure, at 2 hrs after procedure start on postoperative day 0

    Range: 3-5 cm. Higher score indicates greater displacement and less utility of gastric point-of-care ultrasound in these patients.

  • Gastric antrum Cross-sectional area (CSA)end of the individual's procedure, at 2 hrs after procedure start

    Range: 1-10 centimeters squared. Gastric antrum Cross-sectional area (CSA) is a calculated product of Anteroposterior (AP) Diameter and Craniocaudal (CC) diameter. (CSA = AP x CC) Higher score means that patient has a larger gastric volume and is at a higher aspiration risk.
