CAPD Removal

CAPD removal

CAPD removal is a small surgical operation that occurs when the catheter is not necessary anymore- usually related to transplantation, to the use of hemodialysis, periodic infections, malfunctions, or the catheter related complications.

Reasons behind CAPD Catheter Removal

• Transition to hemodialysis
• Kidney transplant successful.
• Frequent catheter or peritoneal infections.
• Malfunctioning or blockage of catheters.
• Tunnel or exit-site infection.
• Catheter has ceased to operate or has leaked.

CAPD catheter removal

Extraction of the CAPD catheter is in general a minor surgical procedure and is carried out under local anaesthesia, unless specific reasons require sedation or general anaesthesia.

Preparation 

• Medical history and dialysis status review.
• Physical exam to determine signs of infection.
• Blood tests in case of necessity (CBC, coagulation profile)
• Prophylactic antibiotics can also be administered particularly in the case of past exit-site/tunnel infection.
• Abdomen debrided and covered in sterile.
• Local anaesthesia in place of exit site (typically lignocaine) and the catheter tunnel.

Procedural Steps

Step 1: Incision at Exit Site

• A minor cut (12cm) is done around the catheter exit point.
• Extrinsic cuff (when it is available in terms of exit site is exposed).

Step 2: Dissection of Tunnel

• The surgeon freed the catheter of the subcutaneous tunnel using blunt dissection.
• The deep cuff (which is located close to the rectus sheath) is meticulously divided with the surrounding tissues.

Step 3: Extraction of Peritoneal Cavity.

• The catheter is slowly removed out of the peritoneal cavity.
• When the deep cuff is highly adherent then a little larger incision can be made right over it.

Step 4: Inspection

• The catheter removed is inspected to ensure that it is not tipped or cuff.
• The peritoneal incision heals without the need to stitch internally.

Step 5: Wound Closure

• The tunnel tract is irrigated in case of previous infection.
• The wound on the skin is stitched with absorbable or non-absorbable sutures.
• It is covered with a sterile dressing.

Duration of Procedure

• Simple removal: 15–25 minutes
• In case adhesions/infection is present: 30-45 minutes.

Recovery Strategy

• Same day (outpatient) patient can go home.
• It is usually associated with mild pain or discomfort of 24-48 hours.
• Dressing should be clean and dry.

Aftercare

• Limit heavy lifting during 1-2 weeks.
• Keep the site dry; sponge bath is better during 48 hours.
• Observation of infection (color, pus, fever)
• Suture removal follow-up (where necessary)

CAPD catheter removal infection

Among the most reasons to remove a CAPD catheter is infection. In cases of infection of exit site, tunnel or recurrent or severe peritonitis, catheter removal is crucial in avert complications.

Categories of Infections that result in Removal

Exit-Site Infection

• Swelling, pus, or redness at the exit site.
• Antibiotics are normally administered but may need removal in case:
• Infection is not responsive to treatment.
• The infections continue to happen regularly.

Tunnel Infection

• The catheter transmits infection beneath the skin.
• Characteristic of pain, swelling and tenderness along the tunnel.
• Risks of developing peritonitis are high, thus catheter removal is frequently advised.

Peritonitis

• Serious infection within the peritoneal cavity.
• Bacterial or fungal cause.
• Signs: pain in the abdomen, fever, hazy effluent.

Removal of CAPD Catheter in the presence of Infection

The procedures are analogous to regular removal but with extra precautions:

Pre-Procedure

• Wide-spectrum or narrow-spectrum antibiotics are administered.
• In case of fungal infection → antifungal treatment.
• Tunnel abscess can be evaluated on ultrasound.
• Surgical procedure--localized anaesthesia or under sedation.

Surgical Steps

• Infected tissue may require larger dissection or greater care.
• Pus/abscess drainage along the tunnel.
• Complete catheter with both cuffs taken out.
• Any contaminated or necrotic area is washed.
• Tunnel tract can be sprayed with antiseptic solution (at the discretion of the surgeon).

After Removal

• Wound not healed up, especially when badly infected (to allow drainage)
• Daily dressing changes
• Take 7-14 days (or more days based on type of infection) of antibiotics.
• Antifungals in fungal peritonitis were usually prolonged to 2-3 weeks.

CAPD catheter removal recovery

The post-CAPD catheter removal is generally uneventful particularly in the absence of infection. The duration of healing will also determine the case of whether it was a routine removal or an infection-related case.

Short-term Recovery

Right after removal

• You can normally go home on the same day.
• Slight abdominal or exit-site pain is usual.
• Dressing is used, and should be clean and dry.
• Light exercises are allowed and should not be straining.

Pain

• Mild to moderate for 1–2 days
• Managed using paracetamol or painkillers prescribed by the doctor.
• Should not use NSAIDs without nephrologist authorization.

Wound Care After Removal

First 48 hours

• Keep dressing dry
• Sponges are better; no showers.
• Do not take the dressing off unless ordered.

After 48 hours

• You can have a shower, but you should not press water directly on the wound.
• Change dressing every day or when necessary.

Sutures

• If non-absorbable: removed in 7-10 days. 
• And, in case absorbable: no debridement required but site must remain clean.

Activity Restrictions

Avoid for 7–14 days

• Lifting heavy objects
• Bending sharply at the waist
• Strenuous exercise
• Tub baths, swimming or soaking up the wound.
• Light walking is encouraged.

CAPD catheter removal complications

Removal of CAPD catheters is usually safe but they may result in complications particularly where the catheter was removed because of infection, adhesions or prior peritonitis. The number of complications is mostly minor and can be treated, whereas severe complications are not common.

Wound-Related Complications

• Infection
• Bleeding / Hematoma
• Delayed Wound Healing

Abdominal Complications

• Persistent Fluid Leakage
• Peritoneal Infection / Peritonitis
• Injury to Surrounding Structures

Other Complications

• Pain or Discomfort
• Recurrence of Infection
• Adhesion Formation

Conclusion

CAPD catheter removal is a procedure that is relatively simple and safe and is conducted when the catheter is unnecessary or malfunctioning or with infection. The recovery is generally rapid, and the pain is slight and the lifestyle limitations are few. A smooth recovery is characterized by proper surgical technique, aseptic care, and wound management of the post-procedure. Infection-related removal can take longer to heal and close monitoring is necessary to patients when compared to those subjects to routine removals, which normally takes 1 to 2 weeks to recover fully.
