twenty years, from 1989 to 2010. For this purpose, we retrospectively studied the

complications and the survival of the peritoneal catheters placed in our PD patients
with end stage renal disease (ESRD). Catheter survival was assessed by Kaplan-Meier
method and the causes of catheter loss were also recorded.

Results: A total of 360 Tenckhoff peritoneal catheters were placed in 322 patients
(177 men, 145 women) with a mean age of 63±13 years old. Of the 360 catheters,

337 were inserted by a nephrologist with the percutaneous- trocar method and 23
catheters were inserted by a surgeon with the small-laparotomy technique. There

was not any serious early or late complication related to the insertion technique. The
survival of catheters placed with a trocar was 86% at the first year, 71% at 3 years,

61% at 5 years and 49% at 8 years respectively. Causes of catheter loss were the
following: infection (peritonitis, exit site infection, subcutaneous tunnel infection) in

71 cases (19,7%), technique failure (ultrafiltration failure, dialysis inadequacy) in 61
patients (16,9%), mechanical causes (dysfunction, obstruction, leakage, hernias) in
38 cases (10,5%), transplantation in 19 patients (5,4%), while in 171 cases (47,5%)

catheter loss occurred due to patients' death.

Conclusions: We conclude that the percutaneously insertion of peritoneal catheters

by expertise in the method nephrologists remains a safe and effective method,
without the need of an operating room as used by surgical methods, while providing

an equivalent catheter survival.

Abstract

Aim: Thyroid cancer comprises the most common endocrine malignancy and a

variety of studies have examined the incidence of microcarcinomas in benign thyroid
disorders. Objective of the present retrospective study was the assessment of the
