| Abstract|| |
Tenckhoff catheter placement is a well established procedure to facilitate continuous ambulatory peritoneal dialysis (CAPD) in end-stage renal disease (ESRD) management. The removal and replacement of the catheter following complications adds morbidity in an already immunocompromised patient of ESRD. A salvage procedure with partial replacement was undertaken in four patients on CAPD. By catheter repositioning, the complications of catheter removal (like wound hematoma, abscess, need of break-in period hemodialysis) and of reinsertion (like leak, obstruction, migration, infection and failure) are avoided. It also reduced the economic burden of insertion in a new catheter.

| Introduction|| |
Tenckhoff catheter placement is well established to facilitate continuous ambulatory peritoneal dialysis (CAPD) in the treatment of end-stage renal disease (ESRD). Complications of these catheters, while in situ, are well documented.  The removal and replacement of Tenckhoff catheter for these complications adds morbidity in an already immunocompromised patient of ESRD. We present details of the catheter problems encountered in 4 patients on CAPD over a span of 13 years and describe the salvage procedure of partial re-implantation undertaken in them. Four patients.
| Case Reports|| |
A 60-year-old female, who was on CAPD for 7 years, presented with channel perforation of the Tenckhoff catheter. She had no mechanical or infective complication earlier. At presentation, she complained of leak from a perforation of Tenckhoff catheter. She was afebrile with stable vitals. On examination, there was a 2 mm longitudinal crack, 2 cm distal to the skin exit site of the catheter with stenosed distal channel. Peritoneal fluid leak was easily discernible at the site of the crack. There was no pericatheter leakage, edema, or induration at the exit site. Leukocyte count of catheter fluid was within normal limits and culture was sterile. Based on the clinical diagnosis of Tenckhoff catheter's crack, we planned for partial reimplantation. The surgical procedure was performed under local anesthetic 1% lignocaine. We placed the skin incision over the previous scar of catheter insertion. Dissection was carried out along the proximal normal portion of catheter so as to gain adequate length from the looped internal part, which was then exteriorized along with outer Teflon cuff superior to the incision line. This partial replantation was accomplished by excision of catheter proximal to the crack site and fitting the tungsten adapter at the cut end [Figure 1]. Immediately following the procedure, CAPD was re-started and she is undergoing regular dialysis for last 6 months without any complications.

The second case was a 41-year-old male patient who was on CAPD for 2 years. He presented with perforation in the catheter due to accidental injury by a surgical blade while removing the dressing. This was managed in a similar manner to that mentioned earlier. He was on regular dialysis for next 3 years without any catheter-related complication.
The third case was a 45-year-old male, who presented after 15 months of CAPD catheter insertion, with perforation in the Tenckhoff catheter. The cause of the perforation was frequent cleaning of catheter with spirit. Partial reimplantation was performed. He was advised to avoid any alcoholic antiseptic for catheter care and he continued dialysis from the same catheter for the next 4 years.
The fourth case was a 50-year-old female patient who reported with aneurysmal dilatation and kinking of the Tenckhoff catheter at the exit site after 3 years of CAPD insertion [Figure 2]. The cause of the problem was not known. Due to very short length of the normal proximal part of the catheter, it required not only partial reimplantation but also attachment of the extension channel to the catheter in situ. In the follow-up at 6 months, she was not suffering from any CAPD-related problems.

| Discussion|| |
Tenckhoff catheter insertion for CAPD is a procedure associated with significant surgical morbidity. It is associated with both early and late complications like catheter migration, catheter obstruction, exit-site/tunnel infection (ESTI), leak from the main incision, wound infection, post-insertion peritonitis, and hemoperitoneum. ,
Removing a catheter because of intractable ESTI seems to be justified by the fact that presence of foreign bodies, such as the catheter, usually makes complete eradication of infective pathogens difficult. The cuff and the catheter, once invaded by infective pathogens, are apt to provide a milieu of persistent colonization. In such situation, removal of the whole catheter may be mandatory if the tunnel infection has extended to the inner cuff area (usually diagnosed by the presence of tender swelling in the proximal tunnel region or by sonographic finding of fluid accumulation in that region); otherwise, removal of a part of the catheter is sufficient to treat ESTI. Total replantation and even partial replantation have been the established treatment modalities for ESTI. ,
However, partial replantation of Tenckhoff catheters is indicated for patients who meet the criteria like positive culture of exit-site discharge with negative culture of ascites, erythema, or tenderness localized over the exit site or the distal part of the tunnel, relapse or no response after antibiotic therapy for 3 weeks, and no sign of infection over the internal cuff area but near-cuff perforation of the catheter which is a troublesome problem. High risk of ascending infection, irritation of exit site, and painful sensation are noted after repairing the perforation with glue.  Wu et al. performed partial reimplantation in 26 cases out of which 24 cases had ESTI and 2 cases were due to channel perforation. They used extension channel as a new double-cuffed catheter connected to the native one by a segment of siliconized tube and always removed the native cuffed channel.  On the other hand, in our series of four cases, the cause of intervention was perforation and channel aneurysm instead of ESTI. We preserved the proximal normal portion of catheter, exteriorizing it with the outer cuff, and there was no need of extension channel except for the fourth case where there was an inadequate length of proximal normal catheter. Hence, the added economic burden of using extension channel for every replantation is unwarranted.
By repositioning the catheter, we avoided not only the complications of catheter removal like wound hematoma and abscess, but also the need of break-in period hemodialysis and its complications.  Besides psychological benefits, it also reduced the economic burden of reinsertion without compromising the outcome. Partial reimplantation of a Tenckhoff catheter is a simple and effective procedure for patients with near-cuff perforation of the catheter.
