Die komplette Resektion mittels Pankreatoduodenektomie (Whipple-Operation) ist die einzig kurative Therapieoption bei periampullären Adenokarzinomen. Bei fortgeschrittenem Tumorleiden kann hierzu eine venöse Gefäßresektion mit anschließender Rekonstruktion notwendig sein. In dieser Arbeit erfolgte die retrospektive Auswertung der von Januar 2003 bis Februar 2013 am Universitätsklinikum Würzburg durchgeführten Eingriffe dieser Art. / Complete resection using pancreaticoduodenectomy (Whipple operation) is the only curative therapy option for periampullary adenocarcinoma. In advanced stages of the disease vascular resection and reconstruction can be required. In this dissertation we conducted a retrospective study at the Universitätsklinikum Würzburg and analyzed all patients who underwent the mentioned surgical procedure between January 2003 and February 2013.

Purpose Extended resections in hepatopancreatobiliary (HPB) surgery frequently require vascular resection to obtain tumor clearance. The use of alloplastic grafts may increase postoperative morbidity due to septic or thrombotic complications. The use of suitable autologous venous interponates (internal jugular vein, great saphenous vein) is frequently associated with additional incisions. The aim of this study was to report on our experience with venous reconstruction using the introperative easily available parietal peritoneum, focusing on key technical aspects. Methods All patients who underwent HPB resections with venous reconstruction using peritoneal patches at our department between January 2017 and November 2021 were included in this retrospective analysis with median follow-up of 2 months (IQR: 1–8 months). We focused on technical aspects of the procedure and evaluated vascular patency and perioperative morbidity. Results Parietal peritoneum patches (PPPs) were applied for reconstruction of the inferior vena cava (IVC) (13 patients) and portal vein (PV) (4 patients) during major hepatic (n = 14) or pancreatic (n = 2) resections. There were no cases of postoperative bleeding due to anastomotic leakage. Following PV reconstruction, two patients showed postoperative vascular stenosis after severe pancreatitis with postoperative pancreatic fistula and bile leakage, respectively. In patients with reconstruction of the IVC, no relevant perioperative vascular complications occurred. Conclusions The use of a peritoneal patch for reconstruction of the IVC in HPB surgery is a feasible, effective, and low-cost alternative to alloplastic, xenogenous, or venous grafts. The graft can be easily harvested and tailored to the required size. More evidence is still needed to confirm the safety of this procedure for the portal vein regarding long-term results.
