BACKGROUND: The interest of laparoscopy in the preoperative staging of pancreatic head adenocarcinoma before curative pancreaticoduodenectomy is a matter of controversy and depends on the accuracy of preoperative imaging techniques. AIM: To assess the potential value of laparoscopy when a standardised and optimal preoperative staging is performed, including spiral computed tomography (CT) and endoscopic ultrasonography (EUS). METHODS: All consecutive patients operated on with a view to curative pancreaticoduodenectomy for pancreatic head or ampullary adenocarcinoma in our centre from January 1998 to August 2000 were retrospectively studied. All of them had preoperative spiral CT and EUS. Tumour resectability was considered as highly probable (HP) or uncertain (U) according to well-defined criteria. Operative records of patients were reviewed to indirectly assess the effective resectability rate and the criteria responsible for unresectability and which of them would have been identified by laparoscopy if initially performed. RESULTS: 69 consecutive patients were studied. Resectability was HP (n = 56) or U (n = 13) after preoperative staging. Curative pancreatoduodenectomy was performed in 53 patients (77%) (48 HP, 5 U). Positive predictive value of preoperative imaging for highly probable resectability was 86% (48/56). Among the 16 unresectable tumours (8 HP, 8 U), the cause of non-resection would have been found at laparoscopy in 9 patients (56%) (6 HP, 3 U). Finally, if initially performed, laparoscopy would have avoided laparotomy in 9/69 patients (13%) (6/56 HP (11%); 3/13 U (23%)). CONCLUSIONS: With accurate preoperative staging using spiral CT and EUS, laparoscopy would detect tumours which were unresectable in 13% of patients with pancreatic head cancer. Laparoscopy remains useful in selected patients, such as those with preoperative uncertain resectability, in whom it can prevent unnecessary laparotomy in one fourth of patients. Copyright 2004 S.
