quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth -

"The most frequent complication in the first month is outflow failure, which is usually caused by omentum or remnant portions of the omentum obstructing the catheter. If there are inflow problems as well, the trouble may be due to malposition. Laparoscopic exploration, repositioning, and cleaning out of the catheter can be successful, but replacement is necessary in most cases. Leakage is also common immediately after placement. It can be treated by decreasing the amount of dialysate and increasing the number of exchanges. Nearly all of these leaks will seal with conservative management unless the inner cuff has been dislodged."
