282 Cholecystoappendicular Fistula- 1st Ever Reported Case
Abstract A 30-year-old male presented with a history of recurrent episodes of acute cholecystitis; first acute attack associated with fever and nausea was 18 months prior to this presentation, for which he was managed conservatively for acute cholecystitis with antibiotics and analgesia following an ultrasound that showed features of acute cholecystitis with no obvious gallstones. The patient had further episodes of acute cholecystitis with no signs of obstructive jaundice and subsequent ultrasound showed multiple small gallstones. Due to the severity of his symptoms, he was scheduled for a planned cholecystectomy. During surgery (right subcostal incision)- findings were that of a contracted gall bladder with dense adhesions, after careful dissection a fistulous tract between the appendix and gallbladder was identified along with a cholecystoduodenal fistula. An en-bloc cholecystectomy plus appendicectomy was performed with the duodenotomy repaired. On the first day post op there was approximately 300 ml of bilious effluent in drain, a white cell count-8.1 x 109 and hemoglobin -12.1 g/dL, Serum bilirubin-1.4mg/dL, ALP-104mg/dL. The second and third post-operative days were uneventful with minimal bile mixed serous fluid in drain respectively with no other complains, following which the drains were removed and patient discharged home. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is a cholecystoduodenal (70%), followed by cholecystocolic (10–20%), and the least common is the cholecystogastric fistula accounting for the remainder of cases. No case of cholecystoappendicular fistula has been reported so far.
