Surgical clip migration in the biliary tract

Area of Science:

• Gastroenterology
• Surgical Pathology
• Biliary Tract Surgery

Background:

• Surgical clip migration into the biliary tract is an uncommon complication.
• Diagnosis of this condition presents significant challenges.
• Previous hepatobiliary surgery is a common predisposing factor.

Purpose of the Study:

• To report three cases of surgical clip migration in the common bile duct (CBD).
• To discuss the diagnostic challenges and potential causes of clip migration.
• To highlight successful surgical intervention for clip removal.

Main Methods:

• Case series reporting three female adults with CBD dilation and migrating surgical clips.
• Pre-operative diagnosis of clip migration.
• Surgical exploration and removal of migrated clips.

Main Results:

• All three patients had a history of hepatobiliary surgery.
• Migrated surgical clips (Hem-o-lok or absorbable) were successfully removed.
• Common bile duct dilation and CBD tumors were noted in the cases.

Conclusions:

• Foreign body reactions to surgical clips can cause migration into the bile duct.
• Continuous compression between the clip and the CBD may also lead to migration.
• Prompt diagnosis and surgical intervention are crucial for successful management.
