| Abstract: | BACKGROUND: Evaluation of peritoneal cytology provides valuable staging information in patients with gastric and pancreatic adenocarcinoma, but its usefulness in patients with extrahepatic cholangiocarcinoma is unclear. The aim of this study was to evaluate the predictive value of peritoneal cytology in patients with potentially resectable hilar cholangiocarcinoma. This study evaluated a possible association between positive peritoneal cytology and percutaneous transhepatic biliary drainage, which is commonly used in these patients and may result in peritoneal biliary leakage and peritoneal seeding. STUDY DESIGN: From October 1997 through June 2000 26 patients with hilar cholangiocarcinoma underwent staging laparoscopy immediately before planned open exploration and resection. Peritoneal washings were obtained during laparoscopic examination before any biopsies were taken. Cytologic analysis was performed using the Papanicolau technique. RESULTS: There were 18 men and 8 women, with a median age of 69 years (range 42 to 81 years). The most common presenting symptom was jaundice (n = 19). Previous biliary drainage was performed in 23 patients: 9 percutaneous and 14 endoscopic. Metastatic disease was suspected preoperatively in six patients, three to the liver, two to the peritoneum, and one to regional lymph nodes, all of which were confirmed at laparoscopy. Laparoscopy identified five additional patients with metastatic disease. Peritoneal cytology was positive for malignant cells in two patients, both of whom had gross peritoneal metastases. Nine other patients had metastatic disease to distant sites within the abdomen, but none had positive cytology. Overall, six patients had metastatic disease to the peritoneal cavity, only one of whom had undergone earlier percutaneous biliary drainage. CONCLUSIONS: Peritoneal cytology was not predictive of occult metastatic disease. Laparoscopic staging identified some patients with unresectable hilar cholangiocarcinoma, but analysis of peritoneal cytology provided no additional information. There was no association between percutaneous transhepatic biliary drainage and peritoneal tumor seeding. © 2001 by the American College of Surgeons. |
