Complications after tenckhoff catheter insertion: a single-centre experience using multiple operators over four years

OBJECTIVE: To analyze the complications after Tenckhoff catheter insertion among patients with renal failure needing dialysis. ♢

PATIENTS AND METHODS: The open, paramedian approach is the commonest technique to insert the 62-cm coiled double-cuffed Tenckhoff peritoneal catheter. All patients with catheters inserted between January 2004 and November 2007 were retrospectively analyzed for demographics and followed for up to 1 month for complications. We excluded patients whose catheters had been anchored to the bladder wall and who underwent concurrent omentectomy or readjustment without removal of a malfunctioning catheter (n = 7). Intravenous cloxacillin was the standard preoperative antibiotic prophylaxis. ♢

RESULTS: Over the 4-year study period, 384 catheters were inserted under local anesthetic into 319 patients [201 women (62.8%); mean age: 49.4 ± 16.7 years (range: 13 - 89 years); 167 (52.2%) with diabetes; 303 (95%) with end-stage renal disease] by 22 different operators. All Tenckhoff catheters were inserted by the general surgical (n = 223) or urology (n = 161) team. There were 29 cases (7.6%) of catheter migration, 22 (5.7%) of catheter obstruction without migration, 24 (6.3%) of exit-site infection, 12 (3.1%) of leak from the main incision, 14 (3.6%) of culture-proven wound infection, 11 (2.9%) post-insertion peritonitis, and 1 (0.3%) hemoperitoneum. No deaths were attributed to surgical mishap. ♢

CONCLUSIONS: The most common complication was catheter migration. The paramedian insertion technique was safe, with low complication rates.
