PD peritonitis in patients undergoing capsule endoscopy: A descriptive study.

Abstract

Peritoneal dialysis (PD) patients who undergo gastroendoscopy and colonoscopy are at increased risk of peritoneal dialysis-associated peritonitis (PD peritonitis) following the procedure (defined as occurring within 7 days of intervention). As per current International Society for PD (ISPD) guidelines, antibiotic prophylaxis is currently recommended pre-colonoscopy in PD patients given the risk of post-colonoscopy PD peritonitis. The risk of PD peritonitis in patients undergoing capsule endoscopy (CE) is unknown. This binational data-linkage study between the Australia and New Zealand Dialysis and Transplant Registry and all hospital admission data sets in Australia and New Zealand evaluated all patients with PD who underwent CE between 2006 and 2015. The objective of the study was to assess the risk of PD peritonitis in patients undergoing CE. Descriptive statistics were used to describe patient characteristics and clinical outcomes. Overall, 23 patients with PD underwent CE. Twelve patients underwent CE alone (i.e. no other concomitant procedures) and none of these patients experienced an episode of PD peritonitis. The remaining 11 patients underwent CE and other invasive endoscopic/abdominal surgical procedures, of whom 2 suffered PD peritonitis. CE is likely a relatively safe procedure in PD patients. PD patients undergoing CE may not require prior antibiotic prophylaxis. Given their relative safety, CE may be an appealing diagnostic tool in a select group of PD patients for the investigation of gastrointestinal disease.
