Complications of Percutaneous and Surgical Gastrostomy Placements in Children: a Single-Centre Series

Gastrostomy placement is a standard procedure for children requiring enteral feeding for more than 3–6 weeks. Various techniques have been described (percutaneous endoscopic, laparoscopy, and laparotomy), and many complications have been reported. In our center, gastrostomy placement is performed either percutaneously by pediatric gastroenterologists, by laparoscopy/laparotomy by the visceral surgery team, or jointly, that is laparoscopic-assisted percutaneous endoscopic gastrostomy. This study aims to report all complications and identify risk factors and ways to prevent them. METHODS: This is a monocentric retrospective study including children younger than 18 years who underwent gastrostomy placement (percutaneous or surgical) between January 2012 and December 2020. Complications that occurred up to 1 year after placement were collected and classified according to their time of onset, degree of severity, and management. A univariate analysis was conducted to compare the groups and the occurrence of complications. RESULTS: We established a cohort of 124 children. Sixty-three (50.8%) presented a concomitant neurological disease. Fifty-nine patients (47.6%) underwent endoscopic placement, 59 (47.6%) surgical placement, and 6 (4.8%) laparoscopic-assisted percutaneous endoscopic gastrostomy. Two hundred and two complications were described, including 29 (14.4%) major and 173 (85.6%) minor. Abdominal wall abscess and cellulitis were reported 13 times. Patients who underwent surgical placement presented more complications (major and minor combined) with a statistically significant difference compared with the endoscopic technique. Patients with a concomitant neurological disease had significantly more early complications in the percutaneous group. Patients with malnutrition had significantly more major complications requiring endoscopic or surgical management. CONCLUSION: This study highlights a significant number of major complications or complications requiring additional management under general anesthesia. Children with a concomitant neurological disease or malnutrition are at greater risk of severe and early complications. Infections remain a frequent complication, and prevention strategies should be reviewed.
