Using the experiences of the extraperitoneal (endoscopic pelvic lymphadenectomy and inguinal hernia repair) and the transperitoneal approach (laparoscopic radical prostatectomy), we developed a totally extraperitoneal approach to endoscopic radical prostatectomy. In view of the favourable short-term outcome, we describe the technique of totally extraperitoneal endoscopic radical prostatectomy (EERPE) as a now standardised procedure. After creating the preperitoneal space by balloon dissection, five trocars were placed in the hypogastrium, allowing immediate access to the space of Retzius. The surgical technique of EERPE replicates the steps of the classical retropubic descending radical prostatectomy with slight modifications. The procedure starts with exposing the Retzius space and pelvic lymph node dissection. After that, the endopelvic fascia and the puboprostatic ligaments are incised, followed by ligating the Santorini plexus. The actual prostate dissection is similar to the open descending approach: bladder neck dissection, freeing of the seminal vesicles, transsectioning of the prostatic vesicles (with or without preserving the neurovascular bundles) and, finally, apical dissection. A water-tight urethrovesical anastomosis is performed with interrupted sutures. There were 20 patients who underwent EERPE. Mean operating time was 170 min with no conversion. No major complications occurred. Only one patient required a blood transfusion. The catheter could be removed on postoperative day 6 (n = 17) or on postoperative day 12 (n = 3). Final pathologic evaluations were 4 stage pT2a, 10 stage pT2b, 5 stage pT3a, and 1 pT3b. Surgical margins were negative in 17 patients. By avoiding entry into the peritoneal cavity, therefore, obviating intra-abdominal complications, such as bowel injury, ileus, or intestinal adhesions, the extraperitoneal endoscopic access provides a safe and minimally invasive approach to the prostate, combining the advantages of minimally invasive laparoscopy and retropubic open prostatectomy.

The preliminary results of this series are promising. Operative and perioperative morbidity was low. Functional results and oncological control were similar to the results of laparoscopic radical prostatectomy. The data demonstrate that endoscopic extraperitoneal radical prostatectomy can be performed with efficacy and results equal to those of laparoscopic radical prostatectomy, while providing the benefits of a totally extraperitoneal approach. Therefore, totally endoscopic extraperitoneal radical prostatectomy represents a technical improvement of laparoscopic technique because it completely obviates intra-abdominal complications and combines the advantages of minimally invasive laparoscopy and the retropubic open approach.

SUMMARY:Are subdural hygromas the result of abusive head trauma? CT and MR imaging represent important tools for the diagnosis of abusive head trauma in living infants. In addition, in-depth understanding of the pathogenesis of subdural hygromas is increasingly required by neuroradiologists, pediatricians, and forensic physicians. Therefore, the current knowledge on subdural hygromas is summarized and forensic conclusions are drawn. The most important diagnostic pitfalls, benign enlargement of the subarachnoid space, and chronic subdural hematoma, are discussed in detail. Illustrative cases from forensic practice are presented. Literature analysis indicates that subdural hygromas can occur immediately or be delayed. If other infrequent reasons can be excluded, the presence of subdural hygromas strongly suggests a posttraumatic state and should prompt the physician to search for other signs of abuse. To differentiate subdural hygromas from other pathologies, additional MR imaging of the infant's head is indispensable after initial CT scan.

During the last decade, laparoscopy has become a standard technique in the armoury of the urologist due to constant technological advances and refinements. Laparoscopic radical prostatectomy (LRPE), although technically demanding and associated with a considerable learning curve, has become the surgical procedure of choice in selected and specialized urological centers around the globe for patients with clinically localized prostate cancer. However, a major drawback of LRPE is the transperitoneal route of access to the extraperitoneal prostate. The principal disadvantages of LRPE are potential intraperitoneal complications, such as bowel injury, ileus, intraperitoneal bleeding, intraperitoneal urinary leakage, intraperitoneal adhesion formation and concomitant small bowel obstruction. Endoscopic extraperitoneal radical prostatectomy (EERPE) is a further advancement of minimal invasive surgery as it overcomes the limitations of LRPE by the strictly extraperitoneal route of access combining the advantages of minimal invasive surgery with those of an extraperitoneal procedure. Based on our growing experience with this procedure, we have introduced several technical modifications, improvements and refinements including a nerve-sparing, potency-preserving approach (nEERPE) in an effort to further improve this minimally invasive procedure.

Life-threatening physical abuse of infants and toddlers is frequently correlated with head injuries. A common variant of the abusive head trauma is the shaken baby syndrome. The present review article sheds light on subdural collections in children with abusive head trauma and aims at providing a recent knowledge base for various medical disciplines involved in diagnostic procedures and legal proceedings. To this end, the different subdural collection entities are presented and illustrated. The pathophysiologic background is explained. Differential and age-diagnostic aspects are discussed and summarized by tabular and graphic overviews. Two problematic constellations frequently occurring during initial CT investigations are evaluated: A mixed-density subdural collection does not prove repeated trauma, and hypodense subdural collections are not synonymous with chronicity. The neuroradiologic analysis and assessment of subdural collections may decisively contribute to answering differential diagnostic and forensic questions. In addition to more reference data, a harmonization of terminology and methodology is urgently needed, especially with respect to age-diagnostic aspects.
