Including 150 randomised patient, the studies aim is to determine whether an economisation and/or improvement in terms of operating time, drainage fluid, blood loss, time of hospitalisation can be found using an ultrasonic dissection device versus traditional surgical methods such as stitches an ligations.The study is performed for patients undergoing partial pancreatoduodenectomy.

Patients Planned for Partial Pancreatoduodenectomy for Pancreatic Head Carcinoma, Periampullary Carcinoma, Chronic Pancreatitis and Other Benign Lesions.

Primary Outcome Measures:
  • Total operation time [ Time Frame: end of operation ] [ Designated as safety issue: No ]
    Measurement of time regarding incision-closure-time

Secondary Outcome Measures:
  • intraoperative blood loss [ Time Frame: end of operation ] [ Designated as safety issue: No ]
  • number of transfusions [ Time Frame: within the first 24 hours perioperatively ] [ Designated as safety issue: No ]
  • hospitalization time [ Time Frame: end of hospitalization ] [ Designated as safety issue: No ]
  • resulting cost reduction [ Time Frame: end of hospitalization ] [ Designated as safety issue: No ]
  • pancreatic fistula [ Time Frame: within the first 5 days postoperatively ] [ Designated as safety issue: No ]
  • postoperative intervention [ Time Frame: end of hospitalization ] [ Designated as safety issue: No ]
    Postoperative interventions due complications, e.g. pancreatic fistula
