Preoperative Use of a Magnetically Controlled Capsule Endoscopy in Patients Undergoing Bariatric Surgery (NAVICAM)

Preoperative Use of a Magnetically Controlled Capsule Endoscopy in Patients Undergoing Bariatric Surgery: A Feasibility Prospective Trial

The goal of this clinical trial is to test if a swallowable camera capsule can safely examine the upper digestive tract in people preparing for weight loss surgery. The camera capsule (called NaviCam® Xpress™ Stomach System) is controlled by magnets from outside the body and doesn't require sedation, unlike traditional endoscopy. The main questions it aims to answer are:

Can the camera capsule be safely used in people with a body mass index (BMI) greater than 38? Can doctors successfully control and move the camera capsule to see the necessary areas of the stomach and esophagus? Researchers will evaluate 30 participants who are preparing for weight loss surgery.

Participants will:

Swallow the camera capsule with water after not eating or drinking since midnight Have their upper digestive tract examined while the doctor controls the capsule from outside their body Complete a brief satisfaction survey about their experience Be followed up with a phone call 2-3 weeks after the procedure

This study could help determine if the camera capsule is a good alternative to traditional endoscopy for people preparing for weight loss surgery, potentially avoiding the need for sedation.

Przegląd badań

Szczegółowy opis

Detailed Description:

The NaviCam® Xpress™ Stomach System represents a novel approach to upper gastrointestinal visualization in the bariatric surgery population. This magnetically controlled capsule endoscopy (MCCE) system consists of a single-use wireless capsule that contains imaging components and magnetic materials that allow external control through a physician-operated magnet.

Technical Specifications and Procedure:

The capsule is equipped with cameras capable of capturing both still images and continuous video footage. After the patient swallows the capsule with 500ml of water, it initially descends the esophagus via natural peristalsis while continuously recording. The capsule is initially attached to a tether, which is released via a 15ml air injection mechanism once the capsule reaches the appropriate position. Once inside the stomach, the external magnetic control system allows the physician to systematically manipulate the capsule's position and orientation, enabling thorough visualization of the gastric mucosa.

Clinical Significance:

This study addresses a critical gap in pre-bariatric surgery evaluation. While traditional esophagogastroduodenoscopy (EGD) remains the gold standard, it presents unique challenges in the bariatric population due to:

Increased sedation risks associated with high BMI Higher technical complexity of the procedure Greater risk of respiratory complications during sedation

Innovation and Technological Advancement:

This represents one of the first applications of MCCE technology specifically targeted at the bariatric surgery population. The study's focus on patients with BMI >38 kg/m² will provide valuable data about the system's performance in body habitus previously considered challenging for magnetic control systems.

The feasibility assessment incorporates multiple technical parameters:

Magnetic control responsiveness across varying body habitus Quality of mucosal visualization in different anatomical regions System reliability and technical performance metrics Procedure duration and technical success rates

This study will help establish the potential role of MCCE in the standard pre-bariatric surgery evaluation pathway and may inform future technological refinements specific to this patient population.

Eksperymentalny: Magnetically Controlled Capsule Endoscopy (MCCE) Arm
Participants will undergo preoperative upper gastrointestinal tract evaluation using the NaviCam® Xpress™ Stomach System, a magnetically controlled capsule endoscopy device. After fasting overnight, participants will swallow the capsule with 500ml of water. The capsule will initially be tethered and will capture images as it descends the esophagus. Once positioned appropriately, the tether will be released via 15ml air injection, and the surgeon will control the capsule's movement in the stomach using an external magnetic control system. All participants will be followed for 14-21 days post-procedure.
The intervention consists of a wireless capsule containing cameras and magnetic materials that enable external control. After overnight fasting, participants swallow the capsule with 500ml of water. The capsule is initially tethered and captures images as it descends the esophagus. Once appropriately positioned, the tether is released by injecting 15ml of air. A trained surgeon then controls the capsule's movement within the stomach using an external magnetic control system, allowing systematic visualization of the upper gastrointestinal tract mucosa. The procedure is performed without sedation and takes place at the Main Campus M60 facility. The capsule naturally passes through the digestive system after the examination.
