Objective Recent surgical planning software provides valuable tools for evaluating different resection strategies preoperatively. With such virtual resections, predictions and quantitative analyses may be carried out to assess the resec-tion feasibility with respect to tumors and risk structures. In oncologic liver surgery, additional tumors that were not… (More)
In robotic radiosurgery, the compensation of motion of internal organs is vital. This is currently done in two phases: an external surrogate signal (usually active optical markers placed on the patient's chest) is recorded and subsequently correlated to an internal motion signal obtained using stereoscopic X-ray imaging. This internal signal is sampled very… (More)
BACKGROUND Lymphadenectomy is performed to assess patient prognosis and to prevent metastasizing. Recently, it was questioned whether lymph node metastases were capable of metastasizing and therefore, if lymphadenectomy was still adequate. We evaluated whether the nodal status impacts on the occurrence of distant metastases by analyzing a highly selected… (More)
BACKGROUND Since the beginning of the new millennium gender medicine has become more and more relevant. The goal has been to unveil differences in presentation, treatment response, and prognosis of men and women with regard to various diseases. METHODS This study encompassed 1,061 patients who underwent surgery for rectal cancer at the Department of… (More)
BACKGROUND/AIM In contrast to diverticulosis of the colon, jejunal diverticulosis is a rare entity that often becomes clinically relevant only after exacerbations occur. The variety of symptoms and low incidence make this disease a difficult differential diagnosis. PATIENTS AND METHODS Data from all patients who were treated in our surgical department for… (More)
Laparoscopic liver resection has been performed mostly in centers with an extended expertise in both hepatobiliary and laparoscopic surgery and only in highly selected patients. In order to overcome the obstacles of this technique through improved intraoperative visualization we developed a laparoscopic navigation system (LapAssistent) to register… (More)
