A 22-month-old male child was brought to the emergency department by the parents due to protrusion of peritoneal dialysis (PD) catheter from anus for last 3 days. The PD catheter was inserted in another center soon after birth for congenital hypolpastic kidneys, first on the left side and later revised and reinserted on the right due to blockage. The catheter was in continuous use until about 3 months back when PD was discontinued as his renal functions normalized. He was planned for catheter removal but could not go due to COVID-19 lockdown.
He was feeding well, passing stool normally, had no history of fever or vomiting. His abdomen was soft and nontender with the PD catheter in place. Curled end of the catheter was seen protruding from the anus [Figure 1]a and [Figure 1]b. His blood investigations including renal functions were within normal limits. He was started on intravenous antibiotics. X-ray abdomen showed the catheter in place without dilated bowel loops and no free air. Ultrasound showed bilateral echogenic kidneys with poor corticomedullary differentiation and catheter within rectal lumen without any pelvic collection.

Next day under general anesthesia the catheter was flushed with iodine-saline solution. Catheter entry site into the peritoneum was opened. The preperitoneal cuff was dissected, and the catheter was transected below the cuff. The lower segment was pulled out from the rectum to avoid contaminating the tunnel with fecal matter. Abdomen was not explored. Upper end was removed, and main wound was cleaned and closed. Exit site wound was left open. The patient remained well and started feeding next day. He passed normal stools and his abdomen remained soft and nontender. He was discharged 72 h after the procedure with oral antibiotics.
In the pediatric age group, delayed perforation of bowel is not seen even in some of the large series reporting on PD catheter-related complication in children. During the search of English language literature, we came across only 4 previously reported cases of delayed bowel erosion by PD.,,, Exact mechanism of PD catheters eroding the bowel is unknown. Lack of fluid around the catheter leading to dry rubbing of the catheter against bowel has been suggested mechanism of delayed erosion of bowel. This usually occurs when a PD catheter is left unused for a prolonged period following recovery of renal function or post-transplant. Catheter removal only without exploration has been reported in only 5 patients in adult series. Among the reported pediatric cases, only one case with delayed perforation of small bowel underwent removal of catheter only. Ours is the second pediatric case with delayed perforation who was treated with simple removal of catheter and first one with rectal perforation and anal protrusion of catheter treated in such manner.
Following the diagnosis of bowel perforation if the patient is asymptomatic and radiological studies do not show any evidence of leak or collection inside the peritoneal cavity it is recommended that the catheter can be simply removed without exploration or attempt to close the perforation. The patient should be observed closely for any post removal leak especially if the patient is on immunosuppression. Removal of catheter without exploration is contraindicated in a patient showing any signs of peritonitis.
