Gastroscopy-related peritonitis in peritoneal dialysis patients

ISPD peritonitis guideline recommendations: 2022 update on prevention and treatment

Peritoneal dialysis (PD)-associated peritonitis is a serious complication of PD and prevention and treatment of such is important in reducing patient morbidity and mortality. The ISPD 2022 updated recommendations have revised and clarified definitions for refractory peritonitis, relapsing peritonitis, peritonitis-associated catheter removal, PD-associated haemodialysis transfer, peritonitis-associated death and peritonitis-associated hospitalisation. New peritonitis categories and outcomes including pre-PD peritonitis, enteric peritonitis, catheter-related peritonitis and medical cure are defined. The new targets recommended for overall peritonitis rate should be no more than 0.40 episodes per year at risk and the percentage of patients free of peritonitis per unit time should be targeted at >80% per year. Revised recommendations regarding management of contamination of PD systems, antibiotic prophylaxis for invasive procedures and PD training and reassessment are included. New recommendations regarding management of modifiable peritonitis risk factors like domestic pets, hypokalaemia and histamine-2 receptor antagonists are highlighted. Updated recommendations regarding empirical antibiotic selection and dosage of antibiotics and also treatment of peritonitis due to specific microorganisms are made with new recommendation regarding adjunctive oral N-acetylcysteine therapy for mitigating aminoglycoside ototoxicity. Areas for future research in prevention and treatment of PD-related peritonitis are suggested.

Safety of Endoscopy in Peritoneal Dialysis Patients

INTRODUCTION

Endoscopic procedures can provoke peritonitis in patients receiving peritoneal dialysis (PD). The aim of this study was to assess the development of peritonitis after endoscopic procedures in PD patients.

METHODS

We retrospectively reviewed the data from PD patients who underwent endoscopies in 3 tertiary hospitals between 2008 and 2018. The patients were grouped into nonprophylactic, prophylactic, and prior antibiotic therapy groups. The incidence of peritonitis within 7 days of endoscopy was assessed. We also examined the factors associated with peritonitis.

RESULTS

There were 1,316 endoscopies performed in 570 PD patients. The peritonitis rate after endoscopy was 3.0%. Specifically, the peritonitis rate was 1.8% for esophagogastroduodenoscopies, 4.2% for the colonoscopy group, and 5.3% for the sigmoidoscopy group. The prior antibiotic therapy group showed a significantly higher risk of peritonitis (odds ratio = 4.6; 95% confidence interval: 2.2-9.6; P < 0.01). Prophylactic antibiotics were not associated with reducing peritonitis. Therapeutic colonoscopies such as polypectomy were associated with an increased risk of developing peritonitis (odds ratio = 6.5; 95% confidence interval: 1.6-25.9). However, biopsies were not associated with an increased risk of peritonitis.

DISCUSSION

Prophylactic antibiotics did not reduce the risk of peritonitis after endoscopy in PD patients. Therapeutic colonoscopies such as polypectomy and prior antibiotic therapy before endoscopy were associated with an increased risk of peritonitis.

Risk of peritonitis after gastroscopy in peritoneal dialysis patients

BACKGROUND

Peritonitis is a common and serious complication of peritoneal dialysis (PD). Translocation of gut bacteria to peritoneum is an important mechanism, which may be enhanced by gastrointestinal endoscopy.

METHODS

In this retrospective observational cohort study, we identified 450 gastroscopies performed in PD patients within a single centre between 2014 and 2019. Gastroscopy-related peritonitis was defined by peritonitis within 1 week after endoscopy.

RESULTS

A total of 408 endoscopic episodes in 216 patients were analysed after excluding 42 cases with either pre-existing peritonitis before endoscopy, or concomitant biliary, small bowel or large bowel endoscopy. There were 16 episodes of peritonitis within 1 week of endoscopy (3.9%). One-quarter of cases were polymicrobial (four episodes, 25.0%). Logistic regression model showed that patient's age, number of endoscopic biopsies, and histamine-2 receptor blocker use were independently associated with peritonitis, while prior antibiotics exposure was associated with lower risk of peritonitis, odds ratio 0.23 (95% confidence interval 0.06-0.95; p = 0.04).

CONCLUSION

Peritonitis can complicate gastroscopy in PD patients and occurs more often in elderly or after repeated biopsy procedures.

Successful use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) on a pancreatic lesion in a peritoneal dialysis patient without interrupting treatment

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), a well-established minimally invasive gastrointestinal procedure, has been used to diagnose and stage cancers of the pancreas. We describe the successful use of EUS-FNA in a peritoneal dialysis (PD) patient to evaluate a pancreatic cyst. The patient continued on PD immediately after the procedure without using hemodialysis. The patient did not experience any complication such as infection, bleeding, or peritoneal fluid leakage.

Don't Interrupt! A Case Report of Continuing Peritoneal Dialysis After Endoscopic Gastric Tumor Resection

Rationale:

The evidence supporting the safety of restarting peritoneal dialysis (PD) immediately after abdominal surgery and interventions is scant. In particular, there are no reported cases characterizing periprocedural management of PD for patients undergoing endoscopic submucosal dissection for gastric intramucosal tumor removal.

Presenting concerns of the patient:

A 66-year-old female with end-stage kidney disease secondary to diabetic nephropathy, currently on nocturnal automatic PD, presented with new iron-deficiency anemia. Workup revealed an intramucosal gastric lesion proximal to the pylorus, without surrounding lymph node involvement. Endoscopic submucosal dissection was performed with en bloc endoscopic resection of a 5-cm, partially flat, partially sessile mass along the posterior wall and lesser curvature of the gastric antrum. Pathology revealed low-grade dysplasia without features of malignancy. There was no evidence of hemorrhage or leak post-dissection.

Diagnoses:

The clinical presentation was consistent with an uncomplicated endoscopic submucosal dissection.

Interventions:

Peritoneal dialysis was held for 48 hours and restarted thereafter with no complications. The patient did not require bridging with hemodialysis.

Outcomes:

The patient had an uncomplicated post-endoscopic course, with no subsequent episodes of PD-associated peritonitis after at least 6-month follow-up.

Novel finding:

This is the first reported case of PD reinitiation after endoscopic submucosal dissection of a gastric tumor.
