Objective To evaluate the efficacy and safety of X-ray guided endoscopic gastrojejunostomy using stent in treatment of malignant gastric outlet obstruction (GOO). Methods Six hospitalized patients with malignant GOO underwent X-ray guided endoscopic gastrojejunostomy using stent in the department of gastroenterology, Shandong Provincial Hospital Affiliated to Shandong University between March 2017 and June 2017. The technical success rate, clinical success rate, procedure time, adverse events and follow-up were recorded and analyzed in this retrospective study. Results The stent was successfully placed in the 6 patients with 100% (6/6) technical success rate. The mean procedure time was 917±518 min. After the procedure, all patients were fed liquid or semi-liquid diet, and the GOO score system was increased from 0-1 before operation to 2-3 after operation. The clinical success rate was 100% (6/6). Peritonitis was observed in 2 patients during operation, and resolved by abdominal drainage. Gastrointestinal bleeding occurred in 1 patient after operation, which was resolved with conservative treatment. During a mean follow-up period of 786 days (range 32-100 days), there was no recurrence of obstruction symptoms except that 1 patient died because of tumor progress 60 days after procedure. Conclusion The X-ray guided endoscopic gastrojejunostomy using stent is feasible and safe to treat malignant GOO with a reliable short-term efficacy.
