Retrograde jejunogastric intussusception due to suture concretion

Area of Science:

• Gastroenterology
• Surgical Complications
• Medical Imaging

Background:

• Roux-en-Y gastric bypass is a common bariatric procedure.
• Complications can arise years after surgery.
• Small bowel obstruction is a potential adverse event.

Observation:

• A patient presented with acute small bowel obstruction five years after Roux-en-Y reconstruction.
• Computed tomography revealed retrograde intussusception at the gastrojejunostomy.
• Intraluminal suture concretion was identified as the cause.

Findings:

• Preoperative imaging accurately identified the intussusception.
• Endoscopic and intraoperative findings confirmed the diagnosis.
• Literature review indicates this is a rare but significant complication.

Implications:

• Delayed diagnosis and treatment can lead to severe outcomes.
• Awareness of such delayed complications is crucial for clinicians.
• Further research into preventing suture-related complications is warranted.
