Abstract
This study included 945 patients with periampullary tumors as evidenced by clinical findings and imaging studies. It was designed to evaluate the results of resection. surgical and endoscopic palliative procedures. Patients were classified into the following groups:
Group (A): Resection group, included 216 patients.
Group (B): Surgical palliation group; included 1 00 patients.
Group (C): Endoscopic palliation group; included 629 patients.
Pancreaticoduodenectomy was the standard procedure of resection for the 216 (22.9%) patients With resectable disease 183 (84.7%) patients were subjected to PG and 33 (15.3%) patients were subjected to PJ Pathological examination revealed periampullary tumor in 204(94.4%), chronic pancreatitis in 9(4.2%) and others in 3(1 A%) patients. Hospital mortality rate was 3.2% (71216) and postoperative complications developed in 71(33%) of patients: pancreatic leak (10.6%). DGE (8.8%), bleeding pancreatic anastomosis (2.3%), internal hemorrhage (2.3%), collection (11.6%) and bile leak (5. 1%).
Factors that influenced the development of postoperative complications included type of pancmatico-enteric anastomosis. Pancreatic texture and intraoperative blood transfusion of 4 or more blood units.
Patients with resected periampullary carcinomas had a median survival of 19 months. However. survival data are not disease specific being longest with ampullary tumors and shortest with pancreatic adenocarcinoma. Other factors that influenced survival included tumor diameter, tumor differentiation and margin status.
