Abstract BACKGROUND: The necessity to obtain a tissue diagnosis of cancer prior to pancreatic surgery still remains an open debate. In fact, a non-negligible percentage of patients undergoing pancreaticoduodenectomy (PD) for suspected cancer has a benign lesion at final histology. We describe an approach for patients with diagnostic uncertainty between cancer and chronic pancreatitis, with the aim of minimizing the incidence of PD for suspicious malignancy finally diagnosed as benign disease.
METHODS: Eighty-eight patients (85.4%) with a clinicoradiological picture highly suggestive for malignancy received formal PD (group 1). Fifteen patients (14.6%) in whom preoperative diagnosis was uncertain between pancreatic cancer and chronic pancreatitis underwent pancreatic head excavation (PHEX) for intraoperative tissue diagnosis (group 2): those diagnosed as having cancer received PD, whereas those with chronic pancreatitis received pancreaticojejunostomy (PJ).
RESULTS: No patient received PD for benign disease. All patients in group 1 had adenocarcinoma on final histology. Eight patients of group 2 (53.3%) received PD after intraoperative diagnosis of cancer, whereas 7 (46.7%) received PJ because no malignancy was found at introperative frozen sections. No signs of cancer were encountered in patients receiving PHEX and PJ after a median follow-up of 42 months. Overall survival did not differ between patients receiving PD for cancer in the group 1 and those receiving PD for cancer after PHEX in the group 2 (P=0.509).
CONCLUSION: Although the described technique has been used in a very selected group of patients, our results suggest that PHEX for tissue diagnosis may reduce rates of unnecessary PD, when the preoperative diagnosis is uncertain between cancer and chronic pancreatitis.
