Background:
Overall few patients presenting with periampullary adenocarcinomas have resectable lesions. We postulated that rapid diagnosis and treatment would enhance the likelihood of successful resection, improving survival.
Methods:
A retrospective analysis of patients undergoing surgery for resection of a pancreatic or periampullary lesion was conducted. Resection rate, disease stage and survival were evaluated as a function of wait times.
Results:
Pancreatic resections were booked in 355 patients. Of 193 patients with periampullary adenocarcinomas, 119 patients (61.7%) had resectable disease. There was no difference in median time from initial physician consultation to surgery in patients with resectable and unresectable disease (61 days vs. 64 days, respectively). The likelihood of successful resection was virtually identical in patients with wait times ≤ 30 and > 30 days (from surgical consultation to procedure). There was a trend toward a higher T-stage in patients who waited >30 days for surgery (P = 0.055). However, there was no difference in survival as a function of wait time.
Conclusions:
This series does not demonstrate an advantage for rapid diagnosis and surgery, in terms of resection rate and survival. However, further study is required in a larger cohort of patients, to confirm these findings.
