PEG-J replacement for duodenal levodopa infusion in Parkinson's disease patients: a retrospective study.

Background: Reducing percutaneous endoscopic gastrostomies with jejunal extension tubes (PEG-J) related complications is vital to the long-term preservation of duodenal levodopa infusion (DLI) in advanced Parkinson's disease (APD). Here, we provide data on the frequency of complications for both the standard "pull" and the non-endoscopic, radiologic assisted, "push" replacement PEG-J techniques in APD.

Methods: We retrospectively identified all patients treated with DLI from October 2009 to January 2020 at the Movement Disorders Center. Patients features and demographics, PEG-J procedures, causes for any discontinuation, reported complications and mortality were collected. In this cohort, PEG-J replacements were performed using the standard "pull" procedure or the radiologic assisted "push" method. Descriptive statistical analysis, t-test and paired t-test with False Discovery Rate correction was performed.

Results: This retrospective study included 30 APD patients [median age 72 ± 5.6 years; mean disease duration 17.2 + 5.7 years]. Mean treatment duration was 35.6 (30.6) months. Overall, 156 PEG-J procedures were performed, and Nineteen patients (63.3%) had a total of 185 reported complications, 85 of which were peristomal complications. 17 (56.6%) underwent 100 replacement procedures due to complications. The most commonly reported complication for replacement was J-tube dislocation (36%). One patient discontinued treatment after 6 months, due to peripheral neuropathy. Six patients died for causes not related to DLI. PEG-J replacements performed with the "push" method had a higher turnover (5.6 vs. 7.6 mo.), but fewer reported complications (67 vs. 75%).

Conclusion: The overall rate of complications was lower for "push" technique. This result might have been due to a higher replacement turnover that acted as a protective factor.
