Abstract
BACKGROUND: Omental wrapping (OW) is the leading cause of obstruction of the peritoneal dialysis (PD) catheter, which interferes with dialysis treatment. Routinely or selectively performing omentopexy during laparoscopic PD catheter placement has been suggested to prevent OW. However, most of the published techniques for performing this adjunctive procedure require additional incisions and suturing. Herein, we aimed to report our experience in performing omentopexy with a sutureless technique during dual-incision PD catheter insertion. We also performed a comparative analysis to assess the benefit/risk profile of routine omentopexy in these patients. METHODS: This retrospective study enrolled 469 patients who underwent laparoscopic PD catheter insertion. Their demographic characteristics and operative details were collected from the database of our institution. Omentopexy was performed by fixing the inferior edge of the omentum to the round ligament of the liver using titanium clips. For analysis, the patients were divided into the omentopexy group and the non-omentopexy group. We also reviewed the salvage management and outcomes of patients who experienced OW. RESULTS: The patients were categorized into the omentopexy (n = 81) and non-omentopexy (n = 388) groups. The patients in the non-omentopexy group had a higher incidence of OW, whereas no patient in the omentopexy group experienced this complication (5.2% vs. 0.0%, p = 0.033). The median operative time was 27 min longer in patients who underwent omentopexy than in those who did not [100 (82-118) min vs. 73 (63-84) min, p < 0.001]. One patient had an intra-abdominal hematoma after omentopexy and required salvage surgery to restore catheter function. The complication rate of omentopexy was 1.2% (1/81). CONCLUSION: Sutureless omentopexy during laparoscopic PD catheter insertion is a safe and reliable technique that does not require additional incisions and suturing. Routinely performing omentopexy provides clinical benefits by reducing the risk of catheter dysfunction due to OW.
