Abstract:Objective To explore and summarize the therapeutic effect of patients with gastric outlet obstruction (GOO) treated by endoscopic ultrasound-guided gastroenterostomy (EUS-GE).Method The clinical data of 77 patients who underwent EUS-GE due to GOO from March 2017 to June 2021 were retrospectively analyzed. Attention was paid to preoperative assessment and preparation for gastric emptying, the clinical treatment effect, complication rate and improvement of patients’ quality of life after EUS-GE were statistically analyzed.Result All the 77 patients underwent EUS-GE successfully. The score of postoperative GOO increased from 0 or 1 to 1 or 3; European Organization for Research and Treatment for Cancer quality of life questionnaire-core 30 (EORTC QLQ-C30) increased from (6.94 ± 1.04) to (10.39 ± 1.11) (P < 0.01); After operation, 2 patients had stent obstruction, 2 patients had stent displacement, 2 patients had gastrointestinal bleeding, 3 patients had mild acute pancreatitis, and 35 patients had intestinal fistula with fever due to active perforation during operation. After symptomatic treatment, all patients recovered well and were discharged smoothly.Conclusion EUS-GE has the advantages of good curative effect, less trauma and high success rate. It can effectively improve the GOO and improve the patients’ quality of life. However, there are many postoperative complications. Effective preoperative evaluation and postoperative observation can reduce the incidence of postoperative complication.
