Abstract
IntroductionTo report the clinical results of patients with malignant pancreatic lesions who underwent oncological surgery with vascular resection. The type of intervention performed, the types of vascular reconstruction, the pathological anatomy results, postoperative morbidity and mortality, and survival at 3 and 5 years were analysed. MethodsRetrospective, cross-sectional and comparative analysis. We include 41 patients with malignant pancreatic lesions who underwent surgery with vascular resection due to vascular involvement, from 2013 to 2021. ResultsThe most performed surgery was the cephalic pancreaticoduodenectomy (Whipple procedure) using median laparotomy, in 35 of the 41 patients (85%). One of the cases in the series was performed laparoscopically. Type 1 reconstruction (simple suture) was performed in 11 (27%) patients, type 2 in 4 (10%) cases, type 3 (T–T suture) in 23 (56%) cases, and type 4 reconstruction by autologous graft in 3 (7%) cases. The mean length of the resected venous segment was 21 (11–46)mm and the mean surgical time was 290 (220–360)min. 90% (37/41) were pancreatic adenocarcinoma. 83% were considered R0 and there was involvement in the resected vascular section in 41% of the cases. Four patients had Clavien-Dindo morbidity>3 and there were no cases of postoperative mortality. Survival at 3 years was 48% and at 5 years was 20%. ConclusionsThe aggressive surgical treatment with venous resection in pancreatic malignant lesions to ensure R0 and its vascular reconstruction is a feasible technique, with an acceptable morbid-mortality rate and overall survival.
