[Spontaneous cholecysto-cutaneous fistula]

Area of Science:

• Gastroenterology and Hepatobiliary Surgery

Background:

• Spontaneous cholecystoduodenal fistula is a rare complication of gallbladder disease.
• Its incidence has decreased due to earlier diagnosis and treatment of cholelithiasis.

Observation:

• A unique case of spontaneous cholecystoduodenal fistula is reported.
• The fistula's orifice was unusually located in the epigastrium.
• This was the first such case observed in approximately 1000 bile duct operations.

Findings:

• The case underscores the varied presentations of spontaneous biliary fistulas.
• Diagnosis and management strategies for this rare condition are discussed.

Implications:

• Highlights the importance of considering rare diagnoses even with advancements in surgical care.
• The unusual orifice location offers insights into fistula formation pathways.
