PURPOSE Laparoscopic radiofrequency ablation is safe, practicable, and combines minimally invasive surgery with the advantages of laparotomy. However, application of the laparoscopic freehand puncture is restricted because of capnoperitoneum and the consequent fixation of the needle on two different points. The use of a laparoscopic ultrasound probe with a(More)
BACKGROUND Neuroendocrine tumours (NET) are rare and heterogeneous neoplasia. To obtain valid data on epidemiology, diagnostics, therapy, prognosis and risk factors is the aim of the German NET registry. PATIENTS AND METHODS Data from 2009 histologically proven NET were collected from 35 NET centres between 1999 and 2010. Data collection has been(More)
PURPOSE Presently, no markers exist to predict metachronous metastasis at the time a primary colorectal cancer is diagnosed. While aneuploidy indicates poor survival prognosis and elevated carcinoembryonic antigen (CEA) levels the presence of recurrent disease, the predictive value of both markers regarding imminent metachronous metastases is unclear.

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)
AIMS Radiofrequency ablation is gaining popularity as the interventional therapy of choice for unresectable hepatic malignancies. However, little attention has been paid to the importance of operator experience in this therapy. This study aims to evaluate the results of RFA treatment dependent on operator experience and learning curve. PATIENTS AND(More)
BACKGROUND Fournier's gangrene is a necrotizing fasciitis involving the perineal and genital regions. Even today, this often polymicrobial infection still carries a high mortality rate and continues to be a major challenge to the medical community. The purpose of this study was to report our experience with this condition and to compare it with those(More)
BACKGROUND Neuroendocrine neoplasia (NEN) are a rare and heterogenous tumour entity. The subgroup with unknown primary tumour (N-CUP) seems to have a worse prognosis as resection of the primary is necessary for cure. The diagnostics and therapeutic algorithms for N-CUP in a German single centre are presented. PATIENTS/METHODS Analysis of the surgical(More)
PURPOSE The current study was designed to identify prognostic factors for long-term survival in patients with advanced colorectal cancer in a consecutive cohort. METHODS A total of 123 patients were operated because of T4 colorectal cancer between 1 January 2002 and 31 December 2008 in the Clinic of Surgery, UK-SH Campus Luebeck. RESULTS A total of 78(More)
BACKGROUND/AIMS Laparoscopic Radiofrequency-ablation is a safe and effective method for tumor destruction in patients with unresectable liver tumors. However, accurate probe placement using laparoscopic ultrasound guidance is required to achieve complete tumor ablation. After development and evaluation of laparoscopic navigation tools for radiofrequency(More)
Anorectal outlet obstruction constitutes one form of chronic constipation. Combinations of morphological alterations of the pelvis, the pelvic floor and the colorectum are nearly always evident. The goal of the diagnostic work-up is to identify those patients who will profit from a surgical intervention. Resection rectopexy aims at restoring the(More)
