BACKGROUND Secondary hyperparathyroidism (sHPT) is common in patients with chronic renal failure. Despite the initiation of new therapeutic agents, several patients will require parathyroidectomy (PTX). Total PTX with autotransplantation of parathyroid tissue (TPTX+AT) and subtotal parathyroidectomy (SPTX) are currently considered as standard surgical(More)
The aim of the present study was to evaluate the outcome of different surgical procedures for patients on permanent dialysis who underwent initial parathyroidectomy for renal hyperparathyroidism (rHPT). Out of a prospective database of patients who underwent parathyroid surgery for rHPT between 1976 and 2009, patients on permanent dialysis who underwent(More)
BACKGROUND The aim of this study was to validate computed virtual reality simulation as a tool to assess laparoscopic skills and to establish whether the simulator allows differentiating between surgeons with different laparoscopic experience. METHODS 27 physicians at the surgical department of the University of Marburg, Germany, with different experience(More)
The improvement of surgical skills of trainees in Germany often occurs solely in the operating room. In recent years, several countries have established surgical skills labs as an essential part of surgical education, with the goal of improving and refining surgical skills before clinical application. Several years ago, training units were established by(More)
BACKGROUND Preoperative and postoperative laryngoscopy has been recommended for diagnostic and forensic reasons as a standard procedure in all patients who undergo thyroid surgery. The aim of this study was to find a more selective approach by defining patients at risk of developing vocal fold palsy (VFP). METHODS The history of neck explorations, results(More)
Prevention and treatment of secondary hyperparathyroidism (SHPT) in patients on chronic maintenance hemodialysis and of tertiary hyperparathyroidism (THPT) in patients after kidney transplantation is a challenge for the nephrologist and for the surgeon. Indication and results of medical and surgical therapy for SHPT and THPT have remained under discussion(More)
BACKGROUND To investigate the appearance of multiple primary malignancies in patients with sporadic neuroendocrine pancreatic tumors (NEPTs). METHODS One hundred forty-five patients with NEPTs were treated at the Department of Surgery, Philipps-University Marburg. Multiple primary malignancies included tumors that were not considered to be a metastasis,(More)
BACKGROUND Hyperparathyroidism (HPT) is an essential contributor to bone disease and cardiovascular calcifications in children with chronic kidney disease (CKD). Pharmacological and dietary interventions are of limited efficacy; calcimimetics are not yet recommended in children. Parathyroidectomy (PTX) is ultimately performed if HPT becomes refractory to(More)
The frequency of intrathymic parathyroid glands (IPGs) in patients undergoing parathyroidectomy for renal hyperparathyroidism (rHPT) varies considerably between 14.8% and 45.3%. Total parathyroidectomy with autotransplantation and subtotal parathyroidectomy are the most accepted surgical procedures to treat patients with rHPT. However, routine bilateral(More)
Cure of parathyroid carcinoma (PC) requires initial en bloc resection, including resection of all tumor-bearing tissue, with hemithyroidectomy and dissection of the central lymph node compartment. Unfortunately, no reliable preoperative criteria have yet been assessed to indicate a high likelihood of PC. Thus, the aim of the present study was to develop a(More)
