[Complications and troubleshooting at the initial introduction of Levodopa-carbidopa continuous infusion gel therapy: A single-center study].

Levodopa-carbidopa intestinal gel (LCIG) therapy has been established as a device-aided treatment for advanced Parkinson's disease. We retrospectively investigated the issues related to LCIG therapy in patients with Parkinson's disease at our hospital from March 2014 to July 2018. The subjects were 18 patients including nine men and nine women. The mean duration of PD symptoms and motor fluctuation was 14.5 ± 5.9 and 7.2 ± 4.5 years, respectively. The mean age at initiation of LCIG was 60.1 ± 9.4 years and the mean treatment period was 21.1 ± 19.5 months. One hundred and sixteen LCIG-associated issues were observed, including pain at the gastrostomy site (23 cases), hypergranulation tissue (14 cases), skin redness and/or erosions (11 cases), cutaneous infections at the gastrostomy site (eight cases), percutaneous endoscopic gastrojejunostomy (PEG-J) tube occlusion in the gastrointestinal tract (19 cases), irremovable PEG-J tube (13 cases), dislocation of the PEG-J tube (six cases), and breakage of the connector (eight cases). The majority of these issues were easily diagnosed and could be managed by neurologists who are familiar with LCIG therapy.
