Merit of the cuff-shaving procedure in children with tunnel infection

Abstract

Catheter replacement and cuff-shaving are performed as a surgical treatment against tunnel infection (TI) in patients on chronic peritoneal dialysis. The efficacy of catheter replacement is well established, but that of cuff-shaving is not. For the purpose of evaluating the efficacy of cuff-shaving, we compared the time interval between each procedure and subsequent TI. In order to perform this comparison, we reviewed data from 32 cuff-shaving procedures and 29 catheter replacement procedures at Tokyo Metropolitan Kiyose Children’s Hospital in the period from 1 March 1991 to 1 May 2001, retrospectively. There was no significant difference in the time interval between each procedure and subsequent TI ( P =0.284). The incidence of recurrence was no more than 12.5% for the cuff-shaving procedures. The incidence of peritonitis due to post-surgery TI with the cuff-shaving procedures was 9.3% and 6.8% with the replacement procedure ( P =0.725). There was no significant variation in time interval to post-cuff-shaving TI according to the reason for the cuff-shaving procedure. In conclusion, cuff-shaving may be worth considering for TI in adequately selected patients.
