Fallopian Tube Entrapment as a Cause of Catheter Dysfunction in Peritoneal Dialysis: An Unusual Case

Peritoneal dialysis (PD) catheter dysfunction is a common complication, usually related to mechanical factors such as catheter displacement, intraluminal obstruction, or omental wrapping.Fallopian tube entrapment is an exceptionally rare cause of PD catheter dysfunction.We report the case of a 29-year-old woman with end-stage kidney disease (ESKD) secondary to diabetic nephropathy, undergoing continuous ambulatory PD.One month after laparoscopic catheter insertion, she developed complete dialysate flow obstruction associated with hemorrhagic effluent.Abdominal radiography showed no evidence of catheter migration or kinking, and laboratory findings were unremarkable.Conservative measures, including patient mobilization, laxatives, and intraluminal heparin instillation, failed to restore catheter patency.Exploratory laparoscopy revealed tight wrapping of the catheter by the fallopian tube, resulting in obstruction of the drainage holes.The catheter was successfully released and repositioned in the Douglas pouch.Patency was confirmed intraoperatively, and PD was resumed without further complications.This case highlights fallopian tube entrapment as a rare but clinically significant cause of PD catheter dysfunction.Because clinical and radiological findings may be nonspecific, surgical exploration may be required to establish the diagnosis.Laparoscopic intervention allows simultaneous diagnosis and treatment while preserving the PD modality.This unusual cause should be considered in female patients presenting with unexplained catheter dysfunction after common mechanical causes have been excluded.
