Gastric obstruction from the Angelchik prosthesis

Area of Science:

• Gastroenterology
• Surgical Devices
• Gastroesophageal Reflux Disease

Background:

• Gastroesophageal reflux disease (GERD) is a common condition requiring medical or surgical intervention.
• The Angelchik antireflux prosthesis was designed to treat GERD by creating a valve around the esophagus.
• Surgical placement of antireflux devices carries inherent risks and potential complications.

Observation:

• A 47-year-old female patient underwent implantation of an Angelchik antireflux prosthesis for GERD.
• Postoperative monitoring revealed a critical complication within five days of the initial surgery.
• The prosthesis was observed to have migrated from its intended position.

Findings:

• The slipped Angelchik prosthesis led to significant gastric outlet obstruction.
• The mechanical failure of the device compromised its antireflux function.
• Immediate reoperation was required to address the obstruction and device malposition.

Implications:

• This case highlights the potential for Angelchik prosthesis migration and subsequent gastric obstruction.
• Surgeons should be vigilant for early signs of device displacement after antireflux surgery.
• Alternative or improved antireflux surgical techniques may be considered to mitigate such risks.
