An open cholecystotomy or cholecystostomy is a surgical procedure performed to address issues related to the gallbladder, specifically for exploration, drainage, or removal of gallstones (calculi). This procedure is particularly indicated for patients suffering from acute cholecystitis, a condition characterized by inflammation of the gallbladder, often due to the presence of gallstones. Patients who are critically ill and unable to tolerate more definitive surgical interventions, such as a cholecystectomy, may require this procedure as a temporary measure to alleviate symptoms and prevent further complications. During the procedure, a surgical incision is made in the gallbladder to access its contents. If gallstones are identified, they are extracted to restore normal function. The surgeon inspects the gallbladder to ensure that bile can flow freely; if any obstruction is detected, the cystic duct is explored to remove any additional stones. In cases where multiple stones are present, a cholecystostomy tube may be inserted to facilitate drainage. This tube allows for the continuous removal of bile and any remaining stones, and the gallbladder is then closed around the tube, with additional drains placed in the abdominal cavity to manage any excess fluid before the surgical site is closed.
