title: Haemoperitoneum post colonoscopy in a continuous ambulatory peritoneal dialysis patient.
abstract: We present the case of a patient on peritoneal dialysis (PD) who had an uneventful oesophagogastroduodenoscopy and colonoscopy. His peritoneal dialysis after colonoscopy had bright red peritoneal dialysate. The patient was completely asymptomatic and a CT scan was performed which did not reveal any retroperitoneal haematoma and showed no signs of perforation or splenic tear. His PD dialysate cleared up with time. We do not find any such case in the literature in which a patient has had haemoperitoneum after a colonoscopy without any obvious cause to account for it. Our patient was unique due to his CAPD in combination with his immunosuppression for his kidney transplant which may have predisposed him to the intraperitoneal bleed after colonoscopy or it may just have been a normal phenomenon after colonoscopy. More studies need to be done as the realisation of its pathology can prevent unnecessary testing and avoid patient and healthcare worker's anxiety.
