UNLABELLED: Over the past two decades, chronic peritoneal dialysis (PD) has emerged as the first choice pediatric dialysis modality. A recent study visually identified the cause of malfunction of PD catheters at the Red Cross Children's Hospital in Cape Town. The reasons that could be found, lead to changed Tenckhoff insertion-techniques from open to laparoscopic. This included suturing of the tip, omentectomy and ovarian-pexy by laparoscopy. In the present paper we prospectively analyzed, if changed insertion technique lead to an improved outcome.

PATIENTS AND METHODS: 26 Patients required 36 laparoscopic Tenckhoff insertions during the period August of 2003 and July of 2006. Overall a total number of 222.5 catheter-months have been observed. Laparoscopic insertion technique required 3 port placements. The tip of the catheter was sutured to pelvic peritoneum, omentectomy performed through a port site and ovariopexy done when required.

RESULTS: The mean lifespan of all Tenckhoff's was 6.4 +/- 6.3 months. The tip of the catheter was sutured 20 times, omentectomy done in 9 cases and 6 patients underwent ovarian pexy. In the group where the tip was sutured to the pelvic peritoneum catheter life was 8.4 months compared to the non-sutured group which was only 4.1. Omentectomy lead to an overall catheter survival of 8.0 months compared to the no omentectomy group, which had a survival of 5.8 months. The complication-rate concerning early problems and malfunctions in the sutured and omentectomy groups was also lower. Patients who underwent both, suturing of the tip and omentectomy had no malfunctions at all.

CONCLUSION: Omentectomy and suturing the tip can lower the complication-rate and prolong catheter survival. Using these procedures could decrease costs and morbidity and prevent patients from having further operations.
