The patient recently underwent an ultrasound showing a filling defect in the gallbladder, thought to represent cholelithiasis. It was concluded that the symptoms were suggestive of cholecystitis and that cholecystectomy was in order. On admission, a laparoscopic cholecystectomy with lysis of adhesions around the gallbladder was performed, followed by a contrast intraoperative cholangiogram. Persistent rectal pain was present in the patient, and a proctologist on the floor was consulted. A mild anal fissure was identified on flexible sigmoidoscopy. An excisional needle biopsy of the liver was performed due to an abnormal liver function study 3 times. The pathology report indicated normal liver tissue. Diagnoses present at discharge were chronic cholecystitis and cholelithiasis, anal fissure, and abnormal liver function studies.
