ObjectiveTo achieve radical resection of locally advanced pancreatic ductal adenocarcinoma (PDAC), and tested the safety and benefits of intestinal autotransplantation in pancreatic surgery.BackgroundPDAC has an extremely dismal prognosis. Radical resection was proved to improve the prognosis of patients with PDAC; however, the locally advanced disease had a very low resection rate currently. We explored and evaluated whether the combination of modern advances in systemic treatment and this macroinvasive surgery was feasible in clinical practice.MethodsPatients diagnosed as PDAC with superior mesenteric artery involvement and with or without celiac trunk involvement were included. Patients were treated with modified-FOLFIRINOX chemotherapy with or without anti-PD-1 antibodies and were applied to tumor resection combined with intestinal autotransplantation. Data on operative parameters, pathologic results, mortality, morbidity, and survival were analyzed.ResultsA total of 36 consecutive cases were applied to this strategy and underwent radical resection combined with intestinal autotransplantation. Among these patients, 24 of them received the Whipple procedure, 11 patients received total pancreatectomy, and the other 1 patient received distal pancreatectomy. The median operation time was 539 minutes. Postoperative pathology showed an R0 resection rate of 94.4%, and tumor invasion of a superior mesenteric artery or superior mesenteric vein was confirmed in 32 patients. The median number of dissected lymph nodes was 43, and 25 patients were positive for lymph node metastasis. The median time of intensive care unit stay was 4 days. Two patients died within 30 days after surgery due to multiorgan failure. The severe postoperative adverse events (equal to or higher than grade 3) were observed in 12 out of 36 patients, and diarrhea, gastroparesis, and abdominal infection were the most frequent adverse events. Postoperative hospital stay was averagely of 34 days. The recurrence-free survival is 13.6 months. The median overall survival of patients after diagnosis and after surgery was 21.4 months and 14.5 months, respectively.ConclusionsOur attempt suggests the safety of this modality and may be clinically beneficial for highly selected patients with PDAC. However, the experience in multidisciplinary pancreatic cancer care and intestinal transplantation is warranted.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
