Emphysematous cholecystitis following routine colonoscopy.

Cholecystitis is a rare sequela of colonoscopy, the relationship between which has not yet been defined. This case study reviews a rural elderly patient who developed right upper quadrant pain following routine colonoscopy. He developed emphysematous cholecystitis, which required laparoscopy with conversion to open via Kocher's incision and underwent a subtotal cholecystectomy due to the severity of necrosis and inflammation. He had an uncomplicated recovery. Colonoscopy is an important diagnostic procedure, the most common complications of which are haemorrhage and perforation. There are less than 10 cases of associated cholecystitis and no reports of emphysematous cholecystitis. The hypothesized pathogenesis is dehydration and lithogenesis associated with traumatic translocation of organisms, however, no definitive correlation has been determined. Due to the potential health impact, cholecystitis cannot be excluded regarding post-colonoscopy abdominal pain, however, the correlation between procedure and pathology remains unclear.
