Complication rate after gastrostomy placement in children can be reduced by simple surgical steps

AIM: To evaluate if the incidence of postoperative complications after gastrostomy placement is correlated to perioperative parameters or patient characteristics.METHODS: In this prospective observational study, children <18 years of age planned to receive a gastrostomy at partaking clinics between 2014 and 2019 were invited. Pre-, peri- and postoperative variables were collected and followed up 3 months postoperatively.RESULTS: Five hundred and eighty-two patients were included (median age: 26 months, median weight: 10.8 kg), mainly laparoscopic (52.0%) and push-PEG (30.2%) technique used. The incidence of complications was lower in the group of patients receiving a gastrostomy tube that was 2 mm longer than the gastrostomy canal (p < 0.001-0.025), and a thickness of 12 Fr (p < 0.001-0.009). These findings were confirmed by multivariate analysis also including operative technique, age and weight. Patients with oncological disease had significantly higher incidence of pain and infection but the lowest incidence of granulomas (p < 0.001-0.01).CONCLUSION: This study indicates that a 12 Fr gastrostomy tube that is 2 mm longer than the gastrostomy canal is correlated with the lowest incidence of postoperative complications the first 3 months after surgery. Oncological patients had the lowest incidence of granulomas which probably is related to chemotherapy.
