Introduction:
A long-term intragastric feeding is the indication for percutaneous endoscopic gastrostomy (PEG) placement in a patient. The procedure is performed in children with central nervous system (CNS) disorders, congenital heart defects and neoplastic or metabolic diseases. The PEG placement procedure is most commonly performed by a gastroscopy procedure.

Aim:
The study aimed to retrospectively analyse the methods applied and complications following PEG tube insertion in patients of the Regional Specialist Children's Hospital in Olsztyn, Poland, in the years 2000–2019.

Material and methods:
A retrospective analysis was conducted of medical histories and records of children qualified for PEG placement procedure. PEG procedure was performed on 48 children: 24 boys and 24 girls. The mean age was 7 years. PEG was inserted in cerebral plasy in 30 patients, congenital defects in 11 and genetic disorders in 7.

Results and discussion:
The reasons for PEG insertion included dysphagia in 30 children, no weight gain in 7, aspiration of gastric contents to the bronchial tree in 6, and feeding difficulties in 10. Two methods for performing PEG insertion procedure were employed: a gastroscopy alone (31 cases) and a laparoscopic-assisted gastroscopy (17). The following complications were: local complications at the incision site (28), PEG dysfunction (13), vomiting (9), sepsis (2), buried bumper syndrome (1), oesophagitis (1), and gastrointestinal fistula (1).

Conclusions:
The PEG placement procedure is burdened with a significant number of complications, however, they are mainly related to local inflammation or PEG dysfunction.
