title: How to proceed in patients with carcinoma detected after laparoscopic cholecystectomy.
abstract: Carcinoma of the gallbladder is a rare disease. Gallbladder carcinoma is detected in less than 1% of all gallstone operations. With the introduction of laparoscopic surgery and the higher acceptance of this technique, gallbladders are now removed much earlier than they used to be. With the increase of cholecystectomies, the diagnosis of unexpected gallbladder carcinoma became more frequent. We report on how to proceed in patients with a diagnosis of gallbladder carcinoma and discuss the additional problems that have arisen since laparoscopic cholecystectomy became established. From June 1990 to December 1999, we performed 6230 cholecystectomies in the surgical department of Moabit Hospital in Berlin. Of these, 42 (0.6%) were identified as carcinoma. There were 37 women and five men, and the mean age was 69 years. In 16 patients (39%), there was a preoperative suspicion of malignancy. In 26 patients (61%), malignancy was suspected intraoperatively or diagnosed postoperatively after pathologic examination of the resected gallbladder. In these patients, an open repeat operation was necessary in seven cases to achieve an adequate curative resection and staging. This involved additional liver bed resection and lymph node dissection of the hepatoduodenal ligament. Abdominal wall (port site) recurrence in the absence of distant metastasis was present only in two patients. We recommend removal using a bag in all gallbladders with wall thickening, irregularities, or scleroatrophic calcified gallbladder area. In stage Tis or T1, laparoscopic cholecystectomy is sufficient. In stage T2 and T3, we perform a repeat operation with liver bed resection and lymphadenectomy.
