Routine nasogastric tube placement in patients with small esophageal perforation after endoscopic foreign body removal may be unnecessary: a propensity score matching analysis

Abstract

Background Nasogastric tube (NGT) placement is part of the post-operative management of upper gastrointestinal perforation, but its routine use in esophageal perforation (EP) caused by foreign bodies remains unclear. The purpose of this research was to investigate the necessity for routine NGT placement in patients with EP after endoscopic foreign body removal. Methods A total of 323 patients diagnosed with EP caused by foreign bodies at the First Affiliated Hospital of Nanchang University between January 2012 and December 2021 were included in this retrospective study. Patients were divided into the NGT group and the non-NGT group according to whether or not NGT placement was performed. The perforation healing rate, post-operative adverse events, hospital stay, and death rate were analysed using a 1:1 propensity score matching model. Results Before matching, there were 263 patients in the NGT group and 60 patients in the non-NGT group. There were significant differences in the time to treatment, infection, albumin, and types of endoscopy between the two groups, while the length of hospital stay in the NGT group was significantly longer than that in the non-NGT group. After 1:1 propensity score matching, 48 pairs of patients were matched between the two groups. The perforation healing rate, post-operative adverse events, length of hospital stay, and death rate did not show significant differences between the two groups. Conclusions For patients with small EP caused by foreign bodies, routine NGT placement after endoscopic foreign body removal may be unnecessary.
