The definitive closure of the abdominal wall, i.e., a closure of the fascial layer and skin may not be favorable in the treatment of numerous surgical conditions, e.g., peritonitis, trauma, or mesenteric ischemia. In these cases, the abdominal wall is temporarily closed, and a laparostomy is created to facilitate re-exploration or to prevent abdominal(More)
Mortality in mesenteric ischaemia can be reduced by an optimised extent of resection. Up to now, no technique supplementing a surgeon's experience has achieved clinical acceptance. Besides a qualitative interpretation, the new technique of computer-assisted laser-fluorescence videography affords quantification of staining intensities. The aim of this study(More)
The aim of the study was to determine whether the induction of HSP70 by Zn2+ is able to protect the small bowel of rats against ischemia. Twenty-four male Wistar rats (weight 200–300 g) were divided into four groups: (1) saline treatment for 24 h (n=4); (2) Zn2+ treatment for 24 h (n=4); (3) Saline pretreatment for 24 h and ischemia (n=8); (4) Zn2+(More)
Background. Laparostomy is frequently performed in the surgical therapy of mechanical obstruction, peritonitis, or trauma to prevent abdominal compartment syndrome (ACS). Extended incisional hernia is inevitable when fascial closure is missed (up to 90% of cases). Intra-abdominal pressure (IAP) has not yet been evaluated as a criterion for the feasibility(More)
Laparotomy closure relies on the incisional edges as anchor for the suture material. The results of these techniques are not satisfying, with failure rates of up to 20%. To investigate the effect of different conventional closure techniques and a novel "bridging technique" on abdominal wall perfusion an animal study was performed in rabbits. Abdominal wall(More)
Introduction: Preservation of sexual function and voiding capacity after rectal cancer surgery has increased after adopting the technique of nerve-sparing dissection and total mesorectal excision. Still the rate of sexual and urinary dysfunction ranges between 25 and 67 %. The precise locations where nerve damage occurs have not been looked at(More)
Als abdominelles Kompartmentsyndrom ist eine intraabdominelle Druckerhöhung über 20 mmHg mit Anstieg des Beatmungsdrucks und Oligurie definiert. Bei dem primären abdominellen Kompartmentsyndrom bedingt eine Akuterkrankung (Peritonitis, Ileus, Abdominal- oder Beckentrauma) direkt die intraabdominelle Druckzunahme. Das sekundäre abdominelle Kompartmentsyndrom(More)
Since February 1992 local anaesthesia has been routinely used for repair of inguinal hernias at the Surgical Department of the RWTU Aachen. All 607 patients undergoing Shouldice repair of primary inguinal hernia between January 1990 and March 1993 were retrospectively analysed with reference to need for analgesics, length of stay in hospital, and rate of(More)
Every suture technique in surgery aims at connecting tissue structures until stable scar formation has developed. Although the negative effects of high suture tension on the mechanical properties of the developing scar are well known, the applied suture tension has not been standardized and depends on the surgeon's experience. In this study the effects of(More)
Diverticulitis of the vermiform appendix is an often disregarded disease. Diagnosis follows after appendectomy due to inflammatory complications in the form of diverticulitis and appendicitis. Diverticula can also be found as a reason for complaints in histologically unaltered appendix or as an incidental finding. Diverticula of the vermiform appendix are(More)
