Abstract
BACKGROUND: In paediatric peritoneal dialysis patients, pre-emptive omentectomy is discussed controversially and literature provides only little data concerning this issue. Our aim was to evaluate the rate of omentum-majus-related problems in our patients, in whom omentectomy was generally not performed. Furthermore, we were interested in the success rates of laparoscopic adhesiolysis. PATIENTS AND METHODS: Between 09/2006 and 03/2008, we regularly saw 18 peritoneal dialysis patients in whom we retrospectively analysed medical records to determine the rate of catheter-related complications. In addition, we evaluated the success rates of laparoscopic adhesiolysis. RESULTS: During 355 dialysis months in 18 patients, we observed 7 omentum-majus-related obstructions in 6 patients (1/50.7 PM). The median age of the patients affected was 9 years, median filling volume at the time of the obstruction was 671 ml/m (2). Laparoscopic adhesiolysis was successful in 4 out of 7 episodes. In 3 cases, the catheter lumen was plugged by necrotic portions of the omentum and the catheters had to be replaced. CONCLUSION: Our data confirm omentum-majus-related catheter obstruction as a major cause of catheter dysfunction. However, in comparison to literature, it remains unclear to which extent omentectomy can reduce the incidence of catheter obstruction in general (including e. g. obstruction due to coagulation). Thus, the decision to perform an omentectomy should be taken individually after careful consideration. In case of omentum-majus-associated obstruction, early but not late laparoscopic intervention proved to be a successful, minimally invasive technique to restore catheter function.
