title: [Prognostic implication of common bile duct infiltration in adenocarcinoma of the ampulla of Vater after pancreaticoduodenectomy].
abstract: OBJECTIVE
  To investigate the prognostic implication of common bile duct infiltration in the adenocarcinoma of the ampulla of Vater after panreaticoduodenectomy.
  
  
  METHODS
  A retrospective study was conducted on clinical manifestation, pathological behavior and survival data in 102 patients with Vater's ampulla adenocarcinoma, who underwent pancreaticoduodenectomy from Jan 1980 to Dec 2003. The result of patients with the common bile duct infiltration were compared with that of those without.
  
  
  RESULTS
  There were 42 cases in stage I (41.2%), 32 in stage II (31.3%), 27 in stage III (26.5%), and 1 in stage IV (1.0%). As for T stage: 9 cases in stage T1 (8.8%), 40 in T2 (39.2%), 25 in T3 (24.5%), and 28 in T4 (27.5%). As regarding to N stage: 76 cases in stage N0 (74.5%) and 26 in N1 (25.5%). Of these 102 cases, microscopic infiltration in the common bile duct (25.0%) was identified in 26 cases. A significant difference was observed between the patients with bile duct infiltration and those without, in the proportion of pancreatic medullae infiltration: 84.6% (infiltration group) versus 34.2% (non-infiltration group, P < 0.001). Twenty-five cases (24.5%) had recurrence and/or metastases postoperatively, with a median survival of 20 months (range, 2 to 93 months). The overall median survival of the whole group was 46.0 months (2 approximately 192 months), with a significant difference between the common bile duct infiltration group (36 months) and the non-infiltration group (49 months, P = 0.0061). The median non-recurrence survival of the whole group was 43 months (2 approximately 192 months), and a significant difference was observed between the common bile duct infiltration group (35 months) and non-infiltration group (47 months, P = 0.0002).
  
  
  CONCLUSIONS
  If the adenocarcinoma of the Vater's ampulla infiltrated the common bile duct, the invasion to the pancreatic medulla is likely developed, and usually with a poor non-recurrence and overall survival. Therefore, postoperative chemotherapy/radiotherapy is suggested.
