Patient characteristics and procedural and safety outcomes of percutaneous transesophageal gastro-tubing: A nationwide database study in Japan

Abstract

BackgroundPercutaneous transesophageal gastro-tubing (PTEG) is an alternative interventional procedure in cases where gastrostomy is not feasible. However, the safety and complication rates of PTEG have not yet been evaluated. We aimed to describe the characteristics of patients who underwent PTEG and investigate complications using a nationwide Japanese inpatient database. MethodsIn this retrospective cohort study, we used the Diagnosis Procedure Combination database in Japan to identify patients who underwent PTEG from April 2012 to March 2020. The outcomes were the occurrence of complications, invasive treatment within 7 days after PTEG, and tube replacement within 14 days after PTEG. We statistically compared patient background, complication rates, and outcomes using PTEG indications. ResultsA total of 3,684 patients underwent PTEG, which was performed in 1,455 patients for decompression and 2,193 patients for feeding. The patients’ mean age was 73.1 years, and 62.1% were men. More patients in the decompression group had cancer than those in the feeding group. The overall number of complications was 47 cases (1.3%). The most common treatment administered after PTEG was red blood cell transfusion (3.9%), followed by early tube replacement (3.3%). As invasive treatments for PTEG complications, percutaneous drainage and transcatheter arterial embolization were required in 4 and 1 cases, respectively, and no cases required surgery. ConclusionWe performed a descriptive study on PTEG using a nationwide database in Japan. This study also showed a low complication rate after PTEG in the real world. Our findings provide practical information on the safety of PTEG in Japan.
